Okay i only started looking at multirom around 4hours before releasing this, so i am aware we already have a multiROM thread, however i do believe it's outdated, and perhaps unsupported now, so i am merging a supported multirom with my TWRP thread where i will be keeping both updated, thanks to @Tasssadar for bringing multiROM to the android community. I failed hard with outdated sources from adam so i have written my own stuff, but i think iodak is using his .diff
Taken and modified from official thread at Flo
Introduction
MultiROM is one-of-a-kind multi-boot mod for Nexus 7. It can boot any Android ROM as well as other systems like Ubuntu Touch, once they are ported to that device. Besides booting from device's internal memory, MultiROM can boot from USB drive connected to the device via OTG cable. The main part of MultiROM is a boot manager, which appears every time your device starts and lets you choose ROM to boot. You can see how it looks on the left image below and in gallery. ROMs are installed and managed via modified TWRP recovery. You can use standard ZIP files to install secondary Android ROMs and MultiROM even has its own installer system, which can be used to ship other Linux-based systems.
Features:
* Multiboot any number of Android ROMs
* Restore nandroid backup as secondary ROM
* Boot from USB drive attached via OTG cable
You can also watch a video which shows it in action.
Warning!
It _is_ dangerous. This whole thing is basically one giant hack - none of these systems are made with multibooting in mind. It is no longer messing with data partition or boot sector, but it is possible that something goes wrong and you will have to flash factory images again. Make backups. Always.
Installation
Manual installation
Find all needed files here: MOD Edit: Links removed
I think Iodak has the kexec patch so use his Rom, i'm not too sure on how to add a kexec so i'll look into it, this does support KK roms as i tried it, and so has dan.
MultiROM has 3 parts you need to install:
MultiROM multirom.zip - download the ZIP file from second post and flash it in recovery.
Modified recovery (TWRP_Mrom.zip) - download and flash in recovery.
Patched kernel - Iodaks kernel i believe is kexec patched, worked for me, have a play, i use share kernel for KK roms of the same type. I suggest this.
You current rom will not be erased by the installation.
Download links are somewhere below
Adding ROMs
Android
Go to recovery, select Advanced -> MultiROM -> Add ROM. Select the ROM's zip file and confirm.
Updating/changing ROMs
Primary ROM (Internal)
Flash ROM's ZIP file as usual, do factory reset if needed (it won't erase secondary ROMs)
Go to Advanced -> MultiROM in recovery and do Inject curr. boot sector.
Secondary Android ROMs
If you want to change the ROM, delete it and add new one. To update ROM, follow these steps:
Go to Advanced -> MultiROM -> List ROMs and select the ROM you want to update.
Select "Flash ZIP" and flash ROM's ZIP file.

FAQ and other notes
About security
In order to make multi-booting possible, MultiROM has to sacrifice some security measures. Firstly, on secondary Android ROMs, /system is not mounted read-only. While there are other things preventing malicious software from messing with /system, this might potentialy make it easier for such software to attack that system.
Next, MultiROM doesn't work with /data encryption. Not many people who use custom ROMs also use encryption anyway, so that isn't much of a concern.
What do the ROMs share?
All ROMs are separate, except /sdcard, which is shared between all Android ROMs.
How many ROMs can I have?/Where are the ROMs stored?
You can have as many ROMs as you can fit in your /sdcard. All the ROMs are stored in /sdcard/multirom/roms or on an USB drive. This folder is unaccessible in Android, to prevent mediascanner from scanning it. You can either in recovery, or obtain root and go to /data/media/0/multirom/roms.
Can I have different versions of Android working alongside
Yes. As long as you select "Don't shere kernel" when installing the secondary ROM, the systems are separated.
MultiROM recovery says it's 2.6.3.0. Why isn't it updated to 2.6.3.*highernumber*?
It is, it just shows wrong version.
The menu with all the ROMs won't show up during boot, how to fix it?
Either re-flash the MultiROM zip or go to recovery, Advanced -> MultiROM -> Inject curr. boot sector.
The reason for this is that something rewrote your boot.img, which happens for example when you flash a kernel. MultiROM's boot menu is part of the boot image, so it has to be added into it again.
Will you port MultiROM to device X?
No, probably. I won't port MultiROM to any device I don't own, because it is very difficult to provide the level of support I want to provide if I can't test things myself, as proven by the Nexus 4 port. I'll probably keep buying Nexus devices and keep porting MultiROM to those myself, but I can't buy every single device - I'm still a student, all my existing devices were bought using some kind of money grant or donations from users.
But, you can port it yourself, the wiki should give you at least some idea how to do that: https://github.com/Tasssadar/multirom/wiki/Porting-MultiROM
Message from Fluoxetine
I spend a lot of time trying to bring new roms/mods to this and many other devices, this doesn't really cost me anything so i will not ask for money, however i am open to other donations, if you can supply me with a donated spot on a build server that would be great! Otherwise, you can supply me with Drink and Food to snack on whilst i work away, just PM me with an amount and i'll choose a product from amazon and send you my address and info for it to be shipped directly to me Thanks for your time guys.

Ha, it's working... Somtimes it's a bit tricky to install secondary ROMs. To get Zaiben RC8 booting I installed it from a backup.
Pure CM11 (20140220 nightly) without gapps is booting, after flashing gapps in MultiROM it dosn't boot. Only using a backup to create it as secondary works for me...
But no way to install AnyKernels like Iodak9.95 om secondary. For CM/ASOP you can try sharing option, for stock-based the only way is using backup with installed custom kernel...
Since AnyKernel there are no boot images for different roms, so there is nothing to inject...
One downer for me is missing ADB in recovery. I've tried mounting USB-Device first, no way. Device manager in Windows shows nothing.
In bootmenue ADB is working, but it's useless without mounted system, data etc. When I use "adb shell mount -o remount,rw system" I got "mount: can't find system in /proc/mounts"
And I noticed after booting any secondary ROM, primary needs wiping cach/dalvikcache to prevent a bootloop...
EDIT: Got system access from ADB...
Code:
adb shell mount /dev/block/platform/sdhci-tegra.3/by-name/APP /system
Nice work man! Does ADB work in MultiROM? Did you check new hardboot patches? It doesn't need target kernel to be patched anymore.

I don't think ADB works in multiROM, i saw in your patch a few ADB related stuff but in all honesty i think i left them and am still using all the same ones as grouper :') But i will be looking into this.
Also i haven't checked out any of the new hardboot patches, because in all honesty i have no clue what they are :highfive: but i can learn, i'll look into it now I just threw myself at multirom and looked at whatever the other devices had, and then just made it for p880 :3 Touch was an asshole Till i realized all i had to do was change b to an a.
Edit 1: This was the device specific mrom stuff i needed to add https://github.com/Fluoxetine/android_device_lge_p880/blob/TWRP/mr_init_devices.c
Edit 2: Added https://github.com/Tasssadar/androi...mmit/005cf387c1404eac862cc35153d7641d18faef4c this commit manualy, well for the files we had i added, we didn't have lge_devices or reboot.c and reset.c was different :s
Compiling stock CM11 kernel with this patch and see if i can dual boot stock with stock kernel that isnt patched, or cm10.1 with stock cm10.1 selecting "don't share"
Edit 3: Getting Errors with the changes i made, so gonna need some more time to amend them for the p880, i think i might have to call on some other devs to help out with this, i have no idea what i'm doing..
Nice work, could I ask you to prepare multirom uninstaller also?
It is working very well, thanks for this. All I do was I installed a CM-based Kitkat rom (Mokee) in the internal, and for the secondary, I installed stock rom (Zaiben) with kernel sharing enabled. Both roms are working flawlessly.
Thanks man I love your work!!
We can install FirefoxOS and Ubuntu too? MultiRom Manager working?

Can't seem to get anything to boot as secondary, I've tried zaiben and nameless. From backup and from zip, with and without kernel sharing.
Most times device just shuts down, once I got to boot animation and then it froze.
All backups normally boot as primary.
Primary uses latest iodak.
Probably I'm doing something wrong since others report it working.

Try having your device connected to ac power while rebooting to secondary. If that works, then its the same problem as with adams multiboot, but it has two workarounds
Will you keep the non-dualboot twrp ?

You can use this recovery witout flashing the multiboot binarys... And the N7 multirom uninstaller works after editing the updater-script.

When you see in listeted roms with shared boot "remove boot.img" ,you can do this.
When I klicked "share boot" on ROM installation and after flashing it have its own boot.img. Don't know why, those ROMs will not boot on my device...
I lose signal on Miui 4.2.2 and CM10.1.3 dosen't boot.
I use Omnirom 4.4 and Iodak 9.95 as default.
Dual boot would be intresting if Android/data/ of secondary rom was on the external sdcard. I'm not very confident of using a secondary rom sharing that same folder as the primary rom. IMO that could cause some issues. Example: if I uninstall a game I'm secondary ROM the obb file of that ROM will be deleted on primary ROM and vice versa.

love you guy! i like the idea of having multiple roms, but I never got this stuff running not on my Lg 4X either on my nexus 7 - hope to get it working now with this release
Kexec for stock Cm11 kernel?
Can someone patch stock Cm11 kernel with kexec-hardboot ?
Okay so, i have uploaded CM11 stock kernel with a kexec patch, although this is not the same patch as used in iodak or stock patched kernel, i have taken the commits from groupers kernel with kexec and have implemented them into our stock cm11 kernel (took ages, had to do it manually).
This should mean that the target kernels do not need to be patched, only the host kernel needs the patch, i tried this with carbon-kk with my kernel flashed and added Carbon-KK WITHOUT SHARING kernel, then when i selected it to boot, as soon as the screen goes black HOLD THE POWER BUTTON, and then it will boot into the secondary Rom with the stock kernel that comes with it!
Well i think so anyway, Danny is testing for me now, maybe some of you could test it too? I'm not sure what will happen, i only tried it with carbon and my kexec as host, and stock carbon as target.
Link is here for the kernel http://d-h.st/j9Z or just check my folder in OP for the MultiROM stuff
For those who are having signal problems or no mobile internet connection from secondary ROM(s) with kernel sharing, you have to copy the kernel modules (baseband_usb_chr.ko, raw_ip_net.ko, scsi_wait_scan.ko) from internal ROM module folder (/system/lib/modules) to your secondary ROM. Make sure to change the permissions as well.
Just my 20 cents .
not able to flash kernel in secondary roms
hi, i have Enox rom as default rom and i installed omni 4.4.2 kk rom as secondary, and no kernel sharing.
now it boots my Enox rom but doesn't boot omni with error to have kernel with patch
so i go in advance > multirom > select omni > flash zip > and flash iodak kernel 9.95, but it fails every time, i tried iodak 9.5 too, but same,
am i doing something wrong or its not possible to flash kernels in secondary roms?
then what am i supposed to do now?
i really don't wanna change kernel of my default rom, it's working perfect with amazing battery life that i want, but i want secondary roms with different kernels ?
This guide is for the Sprint Galaxy S4 only and as of now it is only compatible with two kernels: KToonsez S4 Kernel 4.4 AOSP (4/17 or later) and PoKernel 1.7 F2FS ONLY Build. This guide CANNOT be used on Touchwiz or Android 4.3 yet. I will update it when and if that becomes possible
*Disclaimer: You are doing this to your phone under your own consent. This is an experimental procedure and may not work on some hardware revisions or on devices where certain conditions are not met. You assume all the risk by flashing any of the software below or changing your filesystems. I am not responsible if your phone does not work based on the method I am describing below. Modify at your own risk.
This guide had to be updated in order to correct misinformation. The guide will follow KT's instructions explicitly until it gets to the formatting of the system partition
***If you want to format your /system partition to F2FS please read that section first as it requires steps to be taken from your currently working AOSP rom!***
First, go this link download the file:TWRP-KT.ALL-IN-1.zip
http://goo.gl/HLz4al
Formatting Data and Cache to F2FS
NOTE: Follow these steps EXACTLY, do NOT add or remove any steps, period!!!!
1. Backup everything from your internal SD to your PC or external SD, since the entire internal SD is going to get wiped out with format!!!!!!!!!!
2. Download the files from the folder that you got these instructions from (Ignore the OLD WAY folder) and SAVE TO THE EXTERNAL SD!!!
3. ONLY DO THIS STEP IF YOU ARE ON AN OLD VERSION OF MY TWRP. Flash TWRP-KT.ALL-IN-1.zip (this is what gives us the ability to format using F2FS)
4. Reboot recovery
5. Go to "Settings" and check the box to force F2FS for data and cache (you can also check the box to include /system partition if you want to convert your ROM's zip to use that too)
6. Go to "Wipe->Advanced" option and wipe the "Cache" partiton
7. Go to "Wipe->Format Data" option (THIS WIPES YOUR ENTIRE INTERNAL SD CARD, all files and folders, all gone so make a backup to your external SD or PC!!!!!!!!!!!!!)
8. This step you have 2 choices:
A. Flash your ROM/gapps to start completely fresh
B. Go to restore option and ONLY restore your "Data" (you can also restore /system if you are doing the f2fs conversion on /system partition too)
9. ONLY DO THIS STEP IF YOU INSTALLED A NEW ROM. Flash my newest kernel (needs to be a kernel dated 05.05.2014 or newer)
10. DONE!!!!!!!!!!!!!
11. KTweaker has a new option under "Tools" screen to "Get Partition info" to double check your work.
Formatting System Partition with F2FS (Required: KT SGS4 Kernel 4/28 or later!)
Steps:
1.) Before doing any F2FS conversion with the above instructions, use your currently working AOSP ROM to grab the AOSP 4.4 Kernel from HERE (4/28 or later only!) and save it to your external memory card
2.) Once it is saved reboot to recovery and install it (Flashing a kernel in TWRP is Install -> Folder where kernel is -> Click KT 4/28 kernel -> Swipe to install -> Clear cache/dalvik -> Main menu -> click advanced -> Fix Permissions -> Reboot to system)
3.) After you are back in your working AOSP ROM with KT 4/28 kernel installed, download the AOSP rom you want to use and save it to your external sd card (You can leave the filename as it is, the program will rename it for you)
4.) Open KTweaker and click "Tools" and at the very bottom choose "F2FS: Convert ROM ZIP"
5.) It will ask you to locate the file, ask if you're sure, and then it will do the conversion; upon completion the zip file that was created will have "-F2FS.zip" at the end of it
6.) Now you can follow the steps above, but when you get to step 9A you will use the "-F2FS.zip" file instead of the standard ROM file
This procedure is necessary because KTweaker changes your favorite ROM to pass the command mkfs.f2fs so that your system partition is formatted to F2FS before the files are installed. I did this myself to verify and it works a treat. One crucial step to remember though is that after you install your F2FS converted ROM you absolutely must install KT's kernel so your phone will boot.
Returning to EXT4
NOTE: Follow these steps EXACTLY, do NOT add or remove any steps, period!!!!
1. Backup everything from your internal SD to your PC or external SD, since the entire internal SD is going to get wiped out with format!!!!!!!!!!
2. Download the files from the folder that you got these instructions from (Ignore the OLD WAY folder) and SAVE TO THE EXTERNAL SD!!!
3. ONLY DO THIS STEP IF YOU ARE ON AN OLD VERSION OF MY TWRP. Flash TWRP-KT.ALL-IN-1.zip (this is what gives us the ability to format using F2FS)
4. Reboot recovery
5. Go to "Settings" and uncheck the box to force F2FS for data and cache (If you checked the box to include /system partition uncheck it first)
6. Go to "Wipe->Advanced" option and wipe the "Cache" partiton
7. Go to "Wipe->Format Data" option (THIS WIPES YOUR ENTIRE INTERNAL SD CARD, all files and folders, all gone so make a backup to your external SD or PC!!!!!!!!!!!!!)
8. This step you have 2 choices:
A. Flash your ROM/gapps to start completely fresh

9. ONLY DO THIS STEP IF YOU INSTALLED A NEW ROM. Flash my newest kernel (needs to be a kernel dated 05.05.2014 or newer)
10. DONE!!!!!!!!!!!!!
11. KTweaker has a new option under "Tools" screen to "Get Partition info" to double check your work.
FAQ
Q: Why can't I use this on Touchwiz?
A: It has been developed for the most recent Linux kernel 3.8 and has been implemented in kernels built for 4.4.x OSP builds. This isn't to say it cannot be used on Touchwiz, it is a filesystem and as long as there is a kernel that offers support for reading it installed on your device it should theoretically work on your hardware. However, this can be proven/disproven by the devs here and I will update this answer if it cannot be implemented in a backwards fashion.
Q: Are there advantages to using F2FS?
A: It is built and intended for use on flash filesystems which our devices run exclusively. So since it was developed for flash memory there will be a benefit to using it as it matures. However, this does not imply that benchmarks will increase or your whole phone will become more responsive, its intent is to have files be accessed and written more efficiently. It is supposedly also built for the long-term user who does not constantly reformat their devices because it is supposed to handle large amounts of old files and cleaning more effectively that EXT4. Source: https://www.kernel.org/doc/Documentation/filesystems/f2fs.txt
Q: Will this trip Knox?
A: No more than installing a custom recovery would. So if you already had a custom recovery (Read: TWRP, PhilZ, CWM) in place you are safe following this guide. For now of course; I do not know if there will be another iteration of Samsung software that locks down the device futher.
Q: Can I clear Cache and Dalvik to troubleshoot after changing my filesystem?
A: I tried this myself and the answer is yes. As long as you are using the F2FS custom recovery made by KToonsez you can wipe Cache and Dalvik from recovery and it will rebuild your system. Something I did notice is that first boot will stay on the splash screen longer with F2FS than with EXT4. I saw it hang on the splash screen of my Liquid rom for an extra minute before actually booting and showing cache rebuild. **Your Mileage May Vary**
Q: Why isn't the System Partition formatted into F2FS?
A: This can be done now with KTweaker. See section above.
Q: What ROMs can I use with this filesystem?
A: Any 4.4.x rom (most are 4.4.2 now) that is compatible with either KToonsez S4 AOSP kernel or Pokernel 1.7 F2FS Only.
Q: In Advanced Wipe, Preload has been added to the options of things to wipe. Should I?
A: Ktoonsez answer found HERE was that he has never wiped preload. So I suggest against it unless you know what you are doing.

Great guide OP! Always nice to have a thread to link to.
I'm sure it's been talked about but your posts doesn't mention the ramdisk files. They're listed but not talked about. Now I'm somewhat limited myself in understanding everything there is to know about these things but are those files to do with eventually formatting the system partition to f2fs?
May be worth putting a little note in there regarding those files... You know how some folks go flash crazy once in recovery lol

Hello again.. Lol
The ramdisk mod is now obsolete as it's already included in the kernel zip, which will automatically determine whether you're still on EXT4 or F2FS and make the required changes to the ramdisk accordingly. So no need to flash anything but the kernel as usual after following the steps.
OK yea I figured it was either to do with what I said or to do with the kernel obviously. Just figured I'd ask anyways
Sent from my SCH-I545 using Tapatalk
I'll be the first to admit that I wasn't entirely sure what the ramdisk files were for. I knew they might have been for advanced users considering they were offered, but not listed in the instructions. I didn't know for sure and I didn't want to use the word "obsolete" because, well, I was so wrong before
I am glad LuigiBull23 jumped in and answered that for us. I'll get it added into the the guide so future users know what they are or are not used for. Keep the questions coming, I love learning about this stuff!

I understand. A lot of people were and still are confused about these files..
In short, during the testing phases of F2FS, KT compiled a separate zip for changes to the ramdisk that in turn would reflect the EXT4/F2FS mount points as a means to avoid possible bootloops and such. It was indeed a success and as a result was included in his kernel.
Now, upon flashing the kernel it is able to determine which partitions are formatted as EXT4 or F2FS and mod the ramdisk accordingly. He only left the files on his server in case he ever needed them again. So they are most definitely OBSOLETE. You certainly wouldn't have gone wrong using the term in this case.
Updated the guide for KT's new all-in-one TWRP recovery that will allow you to switch back and forth between F2FS and EXT4. I used his exact instructions from his guide in all areas except for the system formatting section which I wrote. If you are using his custom TWRP recovery go ahead and grab the new one so you can use it in the future!
F2FS with CM11 Nightly
When I used KTweaker to convert my latest CM 11 nightly, it came back and said that it was done but could not find all the lines to modify. Is this ok?

I know it has been forever since you posted this and I apologize for the late answer, but I imagine that if you received that error you got a bad download of CM11. I've personally converted the snapshot and several nightlies of CM11 and they all passed nicely.
So for anyone getting this, if you get a similar error message: Re-download the ROM you are converting
to bad its still not possible with touchwiz, love to use f2fs on a stock rom for my sgs4-lte.
is it possible in the near future that we can use f2fs on those devices with a Samsung stock rom, using another kernel is no problem.
or is this hard to tell ?
Hello, I've been trying to use this to change my filesystem because I'm coming from CM12 and I'm trying to flash a GPE rom on my S4. But after flashing I am rebooting straight to recovery. Also I'm using the latest TWRP.

Make sure you are using a version of TWRP that support F2FS. I don't think the standard issue TWRP does. @AntaresOne has one that does support F2FS and is based on the latest version (2.8.3.0). That's the one I use. Of course, I'm hooked on his CM12 ROM as well. He does really good work!!

Alright guys, as most of you most likely already noticed, we are preparing our device to run completely on F2FS. This task, however, needs some information and tools, which I will try to provide in this thread. It is WIP, so don't expect too much yet
First of all, we need a F2FS capable recovery. I have compiled both, CWM and TWRP, but CWM seems to have some issues, so please use TWRP for now
The only ROM running on F2FS for now is our unofficial CM11, but I will update the following list as soon as I get to know about another ROM
Unofficial CM11
To install a F2FS ROM coming from an ext4 filesystem (default), you have to do the following steps:
0) make backups (including titanium backup)
1) flash the F2FS TWRP recovery image
2) manually format /system /data and /cache to F2FS (WARNING: internal sdcard will be wiped as well)
3) flash the F2FS ROM
4) flash GAPPS
5) boot
Regarding custom kernels, if you don't use the default kernel, please don't make bug reports. If we know that the ROM and kernel are working properly, then we can go on. But for now, if you run into problems using a custom kernel, please keep it to yourself.
I assume you will want to restore your data after formatting to F2FS, but keep in mind that if you restore your /data partition via recovery, the old filesystem will be restored as well (ext4). This means, you cannot restore your old backup via recovery. However, if you have a Titanium Backup backup, you sure can restore this.
ROM devs
In order to compile a flashable zip, the updater-script has to be altered. But don't worry, you don't have to do this manually I edited the script creating the updater-script and made a patch, which can be found in the 2nd post

Updater-script patch:
The patch in the attachment patches the updater-script (generator) to be compatible with F2FS partitions (proper mounting and formatting).
Save it inside the build dir, then open a shell and cd to the correct path. Now run "git apply <patchname>.patch" and you're good to go
Example:
Code:
cd /path/to/ROM_sources/CM11/build
git apply F2FS_updater-script.patch
cd ..
@laufersteppenwolf Ok, I'm a bit confused: according to what I'm reading here, and on your unofficial CM11 thread, I assume that /system should be formatted with F2FS using the new twrp recovery you uploaded..but reading what @Demetris and @iodak are saying on iodak kernel's thread, it seems like only /data and /cache partitions will be turned to F2FS, while /system will stay on ext4..the same has been said by @Demetris in the official CM11 thread..so, my question is: are you thinking to try developing in different ways? Just to understand where you are pointing to, and to acquire a clear knowledge about the status of your work Thank you guys!

I didn't follow iodak's kernel thread, and lately neither the official CM thread, which is why I can't say anything about those discussions. However, all the above info is still correct, as the /system partition still has to be F2FS (you can take a look into our fstab), at least up til now.
And no, I will not go a different was, as my main goal is to keep our device as unified as possible (hence also all various ROM sources on our p880-dev github for slim, gummy,...). All this F2FS stuff is still in a pretty early stage, which is why there can always be changes.

Mmm, yes, it's clear, reading fstab..thank you. The strange thing which took me asking for that question was the discussion between Demetris and iodak in iodak kernel's thread (about using f2fs only for /cache and /data) Anyway, you are the devs, so let's wait

What is a patch? Can i use a brush to apply it? :silly:
Can you make a cwm flashable zip for us? :silly:
Btw because i have a screen protector this can be applied over it or i need to remove it?

Well, TBH, I don't know how else to describe
as anothe example, let's say we want to compile CM11, and all sources are in ~/CM11 (you ran the repo init command in ~/CM11)
DL the patch and save it under ~/CM11/build, named F2FS_updater-script.patch
then run the following commands in your terminal:
Code:
cd ~/CM11/build
git apply F2FS_updater-script.patch
then you can compile the ROM as usual, but make sure to run repo sync before applying the patch

Hi Revered Developer:
Two questions into one: Is it really worth formating F2Fs, which seems to be yes with a lot of buts, and should we choose Art selected runtime. The ART problem is theoretically ok, better than Dalvik, pratically every time I turn Art on, benchmarks ans subjective feeling od the device got worst: Nexus7Flo and t0lte Note II. We need Xposed installer and surround environment...
http://www.xda-developers.com/search/Art+compilers
using twrp where can i find the option to format /data and /cache to f2fs?
edit: found it, under andvanced wipe
Roms with data and cache f2fs while system ext4
If I have non all-f2fs rom. Can I install it with only data and cache f2fs
Because CM11 is all-f2fs and other roms are not, but @iodak released kernel that is compatible with different f2fs and ext4 combinations.
So what roms I can install with data and cache f2f2 while system is ext4
I'm really confused with this :silly: :silly:
Every normal rom (ext4) can be installed with data or/and cache on f2fs. And you able to update or change rom without problems.

Hey want to ask... I don't have external SD, so if I format to F2FS my internal memory will be wiped right? So, must I push ROM zip to internal memory through ADB to install ROM? or there is any other method?
Thanks.

TWRP 2.7.1.0 multi-mode recovery. 2.7.1.0 v3 was the first release for p500, (thanks to @HardLight for advising, testing, and posting it. And for making a p500 OS2SD ROM to justify it.)
v1 and up are for thunderc (Optimus V/S), there's a separate thread over there in the appropriate forum.
Now with f2fs! Thanks @HardLight
OS2SD/Internal All-In-One. Switch modes under Advanced. It tells you on the title bar which mode it's in.
It'll flash gapps or PurePerformances or what have you to either the p2/p4 sdcard partitions for OS2SD or the internal partitions.
This has a special partitioner to set up your card for OS2SD. In OS2SD mode, go to Advanced then Partition. Set your sizes, it isn't aware yet of the whole card size (yet) so it'll just tell you if you go over and refuse to format it.
Whatever is left after your system/swap/data is your /sdcard size.
If it's in Internal mode the partitioner does sd-ext and swap instead. same deal, the leftover space is your /sdcard size.
Under the Wipe -> advanced menu, you can now select either system or data and press the 'repair or change filesystem' bar at the bottom, select change filesystem, select f2fs.
TLS enabled, system/data MTD swap on internal mode to match post-7/12/2014 androidarmv6 builds. Won't flash older ROMS or ones without the MTD swap correctly.
I am working on making it compatible with older builds too... but not yet. You may have to use a new update-binary to flash older zips. Or grab the older one from this zip file.

I suspect I'll need more than one extra post to cover important stuff that won't fit in the OP.
On the portal today was announced a recovery-switcher app. One could have the mtd swapped and not-mtd swapped recoveries, or a cwm and a twrp recovery on the sdcard and use the app to switch between them. Do not know if this baby would work on a P500, though.
Would rather have a decent all-in-one, but that 5meg limitation may make this impractical (for example, the cwm has lost its sdcard partitioning functions).

that specific mod, you'd have to fix the updater-script to use it for os2sd, because it specifies MTD mounts.
mount("yaffs2", "MTD", "system", "/system");
pa_gapps and CrossBreeder and other more generic zips use
busybox mount /system
//edit: proper syntax:
run_program("/sbin/busybox","mount","/system");
instead of trying to call out the filesystem type.

i'll check the updater script, thanks for the pureperformance thinks, i discover a another method to speed up the p500 :fingers-crossed:
bump
f2fs enabled for OS2SD.
uses updater script like so:
mount("f2fs", "EMMC", "/dev/block/mmcblk0p4", "/data");
to use f2fs /data go into Wipe menu, advanced, select data checkbox, press 'repair or change filesystem' bar, change filesystem, f2fs. accept.
you only have to do that once to change from the default ext4 partition type.
it handles /system f2fs as well.
mount("f2fs", "EMMC", "/dev/block/mmcblk0p2", "/system");
change the filesystem the same way as data.
new 3.0.101 kernel but I noticed no differences in recovery except the working f2fs. Thanks @HardLight.
for now, attached .img for you who really have to experiment. I haven't tested this one very much on thunderg, just thunderc. basics tested on thunderg.
flashable zip added to shared folder linked in OP.
there's a little something extra in the shared folder...
I'm also uploading ROMs for the adventurous.
f2fs-system and f2fs-data os2sd builds if you're brave enough to try them. change both system and data to f2fs in recovery before flashing the rom unless you've already done that with an earlier version.
I don't have cell service to test but it's basically an androidarmv6 build plus 3.0.101 kernel and f2fs os2sd. everything else looks like it works to me.
I added Email, Apollo, Speech Recorder (which tunes up voice search I think), emojii in messaging and aosp keyboard, and extra wallpapers. Including Grass live wallpaper (which does actually work on armv6, it just looks for some network function and errors out ... I patched it,) and it reverts to building libcamera. Plus hackers keyboard because I like arrow and tab in terminal. No voice search in hackers keyboard though.
...
bump for twrp 2.8.0.0
no other fixes or anything, just a rev up for twrp.
I'll upload in an hour or so. //edit: well, maybe not so soon. I can't test at the moment since my o1 went into a no-boot loop. perfectly good running rom on it too. bah.
take me the evening to fix it.

could you say to me if it's normal this:
i make the wipe of the /system in twrp, then if i go to "repair or change fs" it show size 390mb, used 110mb
but if i make a wipe or a "change fs", used space shouldn't be 0mb?
is the same for /data.
i un/mounted the partitions before, but have always some mb used in both.
hum minitool show me that the two f2fs partitions are fully used, maybe it can't read the f2fs, however i've formatted the partitions again in ext4 and now retry the f2fs format via twrp
edit: however, after 2nd format in the end /data have 144 mb used, /system 110mb. so i suspect it's normal

looks normal to me, ext4 uses "only" about 16MB after format but f2fs uses a lot more.
minitool will only work right if your kernel supports f2fs and I doubt m$ware does right now.
and the fix din't get migrated from the overrides in thunderc to p500 yet, sorry, was a 'for fun' build to share after a recent repo sync.
this one probably has a built libcamera instead of the froyo as well. (reversion)

I meant that I can use. HardLight pointed me to the method to enable it... if I hadn't completely fried my firmware. no backlight even, much less lg logo or emergency mode.
eventually I'll find another p500 for development (I can't use gsm phone on my service) but the going rate on ebay is $50 and I can't justify that for a hobby.
unfortunately it's too tweaky and time consuming for me to remotely develop by having someone else debug, so any more p500 stuff will be untested and slightly sketchy because of that.

Hi folks,
finally we compiled a(n un-)tethered TWRP package for our ZenFone 2 (confirmed on ZE551ML and ZE500ML)!
!!! NOTE: If you want to apply a new OTA update, please flash stock recovery first !!!
Also, if you encounter any errors with the official recovery by TeamWin, please don't ask for support here as this is an unofficial build (done with the hard work of many people collaborating in a great manner!)
If you don't want to unlock your Bootloader, you can use the tethered recovery.
Tethered (=after a reboot everything is back to normal)
Features:
- Compiled with CM12 sources (although CM12 and TWRP are not liking each other very much :silly: )
- Optimized for x86 (smooth UI now)
- internal and external storages are mounted correctly
- Backup of boot, system, cache and data possible
- Full Crypto and SELINUX support
Bugs:
- Sometimes Backup and Restore hang. Fortunately it doesn't begin these operations so you don't brick your device (any hints on this are welcome!)
- USB Storage mount doesn't appear to work at all (pretty sure I took the correct path to the LUN file)
How to use:
- Download the tethered CWM package from here (method 2): http://forum.xda-developers.com/zenfone2/general/root-newbie-root-instructions-zenfone-2-t3114063
- replace the recovery.zip in "CWM_Zenfone_2_IntelFB_RecoveryLauncher" with the one you can find in the download section
- start the procedure by using cai_dat_CWM.bat
- type ACCEPT (case sensitive!) and enter
- type T4 and enter
- Set your timezone when booting the first time into the Recovery, maybe this fixes the backup and restore bug (needs to be done just once)
- Unplug your USB cable from the device, too, before flashing, backing up and/or restoring
Untethered (=permanent recovery)
Features:
- Compiled with CM12 sources
- Optimized for x86 (smooth UI now)
- internal and external storages are mounted correctly
- Backup of boot, system, cache and data possible
- Full Crypto and SELINUX support
- kernel compiled dynamically (thanks to @crpalmer and @jrior001 and all involved for their fantastic work) with permissive Selinux
- USB-OTG support added (Beta supports NTFS file systems)
- Splashscreen can be backed up (to fiddle around and create your own)
- img files flashable now via recovery (thanks to @cangcan, @yakub234go and @vampirefo)
- F2FS support on kernel side
Drawbacks:
- MTP doesn't work
How to use:
Method 1
Get root rights
Unlock your bootloader
Download twrp.img from the download section and put on sd card (or pick the beta version for NTFS support)
Fire up adb or install a terminal emulator and type:
Code:
su
dd if=/sdcard/twrp.img of=/dev/block/by-name/recovery
reboot recovery
Method 2
Download twrp.img from the download section and put in your adb/fastboot directory
Unlock your bootloader
Boot into bootloader (turn off, keep Vol+ pressed and press the power button until it vibrates - then release ONLY the power button and keep volume up pressed until you see the fastboot GUI
Open up fastboot on your PC and type:
Code:
fastboot flash recovery twrp.img
Then press vol down 2 times until "Reboot recovery" shows up and press power 1 time to boot into recovery
Method 3 (if you have an older version of TWRP already installed)
Place img on your internal sdcard, then reboot to recovery, click install zip, then select "Images..." in bottom right, then you see the img. Tick "Recovery" afterwards and then on OK.
Download folder:
Gone
Cheers!

Hi,
yes, after rebooting no trace of TWRP is left
I have updated the zip now. It is a little stabler after I removed the CPU temperature, but still I have the feeling there are 2 GUIs sharing the same screen. Weird - I have to do more research - maybe I have to write my own UI updater...
Cheers
the gears are slowly moving! i hope BL gets unlocked by the time my ZF2 arrives..
is this for any ZF2 variant or just 551ML (4gb ram/2gb ram versions)?
thanks for taking the time with this (hopefully) awesome device!
This is awesome..thanks for your contribution! I am hoping for some custom roms..the stock ZenUI isn't the greatest :/

Do you have a link to your device repo?
Are there specific instructions for using it to build a tethered recovery (I'm familiar with building twrp, including within CM, but I haven't looked much into what the tethered exploit does to boot the recovery).
It seems I have successfully completed a Backup! As mentioned, the interface is painfully slow at times, but this is serious progress. Has anybody tried restoring a backup yet?
Could you please develop twrp or cwm for asus 450cg
NOTE:
1 backup successfully
2 Use Very lag
3 flash zip not work

Hi,
unfortunately I don't have any. Basically I wrote a BoardConfig.mk based on the data provided by the Nexus Player (Asus Fugu, which is also Intel based). Then I took 2 modules (one for the display and one for the support of exfat partitions) and compiled a normal TWRP. The output folder holds the compiled img as well as the ramdisk in a simple folder. I put the ramdisk content into a simple zip file and included an update-script to have it unpacked properly. What the recovery-trigger exactly does is not clear to me. It seems it temporarily overwrites the logcat binary with itself and then gets executed at a reboot directly. The recovery trigger just unpacks the zip and executes the recovery binary if I understood correctly.
If you want I can upload my device configuration, it's better if there are more ppl looking at this

Thanks for the feedback!
2. Yeah, the lags are a pain, also because it seems to execute every touch twice and I don't know how to fix this at the moment (maybe it is sufficient to increase the time to determine when a longpress is executed and when a normal touch is done, but this is strongly theoretical.
3. I tested flashing a zip and it does work, which error message do you get?
Anyways, today is a new day, so I will get to work on this (I am on vacation right now fortunately).
Cheers!

If you can upload the device config to github I can try to take a look tonight or tomorrow and see if I can see anything wrong that would explain your "double ui".
Either way, it is good to upload it as you'll have a history saved of when it last worked if you screw it all up!

Is your problems due to recovery or modules you added? My tethered twrp doesn't have the problems yours does, so I wonder if it's the modules, your packaging perhaps and not the recovery?

- Slow graphics, according to @Dees_Troy: "The graphics are a bit laggy because pixelflinger is not very well optimized for x86"

Dees_Troy is lying. TWRP graphic engine isn't optimized for any architecture. Even on my SGS4 (ARM) it's slow as snail. Higher resolution - more slower. I see, they've added some code for Qualcomm overlay support. I didn't try it yet, but support only for one CPU manufacturer is nothing. Especially, there is another way to accelerate at around 1000% by SIMD instuctions. Although i've liked TWRP originally, i see developers have no intentions to improve graphics which is the key feature. So, i've decided to throw away TWRP and look at Aroma File Manager.
It has very fast graphics engine with ARM NEON optimization (and with some effort it become SSE4.2 optimized). The only feature missing is backup/restore, but i'm working on that. Actually, Backup/Restore works now. Just thinking about better backup format.

I know. The problem is how to split the archive. Currently i split by size. In this case you cannot use parts independently. For example, if you want to extract some file, you have to concatenate whole backup first and then extract.
The better way is to split tar at header boundary but so far in many decades of years nobody created such split tool. Also, if there is a file bigger than desired part size, it won't be split and may even produce error if target disk (where backup is saving to) is FAT and file size is bigger than 4GB (extreme case).

@Dees_Troy actually is not lying pixelflinger_static isn't optimize for x86 and Intel used to add libenc to speed up pixelflinger a little, intel later decided to use the more recent version of libminui cause it doesn't use pixelflinger_static and from what i read it a whole lot faster. i imagine @Dees_Troy and team-win are looking into moving away from pixelflinger because of it's draw backs but that is a very big task.
i plan to build against the windriver android-5.0.0_r2.0.1 source this evening cause it includes the icc tool chain when i built the new recovery.launcher against it , it was much much much much much faster hope it has the same affect on twrp

I assume maybe I am missing some modules. There is a .ko file named fps_throttle...this led me to the conclusion that maybe the framerate is awefully high (or awefully low ), which could explain this flickering text maybe...
I will include all of the modules in my next build to see if it works better, thanks for the tip!

I think, you've missed the point. I've said current TWRP graphics isn't optimized for ALL platforms (besides very specific Qualcomm overlay which i had no chance to try). Nothing to do with x86. Even on ARM device it's very slow. In several years of TWRP existence, i didn't see any progress in GUI, so i don't hope it will be changed anytime soon.
From other side, Aroma File Manager uses NEON(which can be translated to SSE) optimization making interface very fast. Thus, you don't need any special compiler. But due to very different internal GUI engines, it's hard to port TWRP to Aroma GUI. Using 3rd party compiler give you other problems if you try to compile something requiring Android NDK.
Anyway, let me know if your approach with different compiler will make rocket from snail TWRP GUI
