[GUIDE] Unpack system.new.dat - Nexus 7 General

I've been struggling with these system.new.dat block images since lollipop came out. I searched high and low for a way to mount that image outside of twrp with no luck. So I just used twrp instead... These are the steps I take:
Clean flash a lollipop rom that has a system.new.dat image in twrp.
Reboot system.
When device finishes booting use hardware power button to power down without messing with the rom itself yet so it stays fresh. (It's ok to confirm power down on touch screen.)
In twrp make a backup of only the system partition.
Boot back to system and use the method you prefer to move the file system.ext4.win from:
/TWRP/BACKUPS/-ur-device-serial/-ur-backup-date
to your pc and rename it system.tar so you can unpack it. (Of course make sure you have the proper decompression tools, which every OS usually does now.)
Now you have the complete fresh contents of /system as you would in a traditional rom zip. You can do with that as you please, or just throw it into a rom kitchen. :silly:

There is also another solution to allow you to unpack and repack the system.new.dat file. See the link below.

Auto-Modify Boot Image [New! Ported to Windows, 23 Aug 2012]

I ported my automatic boot image modifier from Linux/Ubuntu to Windows. As with the Ubuntu version, my auto-modifier redirects ROM filesystem mounts from emmc (internal memory) to SD card (external memory) in the boot image to more quickly boot a ROM hosted on SD.
Features
Simple, lightweight install. No need to separately install Cygwin and required packages.
As with the Ubuntu version, the boot image ramdisk directory is automatically modified to redirect filesystem mounts for /system, /cache and /data from emmc to SD card so you can quickly boot a ROM hosted on SD. No other changes are made, though the Perl code can be altered as necessary to further modify ramdisk.
Tested working on XP using NottachTrix 1.3.1 AT&T boot image file. For Win 7, you may need to tweak User Access Control (UAC) to launch Cygwin.
Note: The unpacker script is just a copy of “split_bootimg.pl“ found here: http://www.enck.org/tools.html (Thanks Bill.)
Instructions
1. Download cygwin-auto-modify-boot.zip (50MB) here: http://www.mediafire.com/?kz9fqzwznzizb1z
2. Unzip files to Windows c:\ . OR, if you already have a fully functioning c:\cygwin build that contains the Perl v5.14.2, cpio and gunzip binaries, you should only need to extract the directory: cygwin\home\modify-boot to c:\. In any event, you should backup your existing c:\cygwin directory prior to unzipping.
3. Copy the original boot image file (boot.img in this example) to c:\cygwin\home\modify-boot
4. Navigate to c:\cygwin and launch c:\cygwin\cygwin.bat . This opens a cygwin command window, and also generates a set of user configuration files if opened for the first time.
5. In the Cygwin command window, enter: cd ../modify-boot . Here is my directory listing after Cygwin configured my system:
6. In the Cygwin command window, enter the command: ./modify-boot.sh boot.img and press Enter at the prompts. For me, the entire process took ~30 seconds to modify a NottachTrix boot image.
If everything goes right, the system creates a “boot-repack.img” file based on the modified ramdisk and stores it in the modify-boot directory. Various log/debug data are presented on screen and stored in the modify-boot directory.
That’s all! From here you can “fastboot flash boot boot-repack.img” to boot your SD-based ROM, or store the modified image in a boot configuration directory. See http://forum.xda-developers.com/showthread.php?t=1645344
Please note: The size of my dev team has never exceeded one (me); yet I will try to field requests for help as I am able.

Many have studied this excellent tutorial on how to unpack, modify and repack Android ROM boot images: http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images. Its contents form a solid baseline for customizing ROM boot images and ROMs in general. Here I attempt to automate the process of modifying boot images.
Results thus far provide an efficient means of booting ROMs that are cloned to SD card (see my clone thread: http://forum.xda-developers.com/showthread.php?t=1764680 ), as shown in the example below.
modify-boot zip: http://www.mediafire.com/?luobv279pcv827k contains five files: three Perl scripts to unpack, modify and repack a boot image, the “mkbootimg” executable, and an executive batch file to run the three Perl scripts in sequence.
Boot image modifier script: modify-bootimg-atrix.pl features a useful example of how customizations can be pre-programmed by including code to redirect ROM filesystem mounts to SD card, thus enabling us to boot SD card-based ROMs --- almost on the fly.
Of course there are many references to customizing boot images, but to my knowledge this is the first published attempt to automate the process. And since there are some interesting projects related to hosting Perl on Android (see References below), I think it would be fun to develop a CWM-flashable zip (or similar tool) that loads a Perl script interpreter and then runs a pre-programmed boot image modifier --- all on phone, without computer aiding.
Preliminaries
Linux-based OS (Ubuntu 12.04 preferred --- it's still free)
Android SDK Platform Tools (includes adb and fastboot)
Perl (Ubuntu 12.04 includes Perl 5.14.2)
Example: Boot Neutrino V2.8 GT cloned to SD card
Suppose we have already cloned Neutrino V2.8 GT ROM (/system, /cache and /data) to SD card. To boot it:
1. Download modify-boot.zip: http://www.mediafire.com/?luobv279pcv827k to Desktop and extract directory: /modify-boot to ~/Desktop
2. Extract boot.img from Neutrino V2.8 GT ROM.zip and drop it in ./modify-boot
3. Open a terminal, get root and cd ~/Desktop/modify-boot
4. Enter: “sh ./modify-boot.sh boot.img” and follow prompts (Output file: boot-repack.img)
5. Boot to fastboot and connect phone to computer
6. fastboot flash boot boot-repack.img
7. fastboot reboot
Once phone is booted, we can run a sanity check by entering:
adb shell (access Android filesystems)
# mount
Results should include the highlighted device names for filesystem mounts:
Code:
[COLOR="Blue"]/dev/block/mmcblk1p2 on /system[/COLOR] type ext4 (rw,noatime,nodiratime,errors=continue,barrier=0,nobh,data=writeback,noauto_da_alloc,discard)
[COLOR="Blue"]/dev/block/mmcblk1p4 on /data[/COLOR] type ext4 (rw,nosuid,nodev,noatime,nodiratime,barrier=0,nobh,data=writeback,noauto_da_alloc,discard)
[COLOR="Blue"]/dev/block/mmcblk1p3 on /cache[/COLOR] type ext4 (rw,nosuid,nodev,noatime,nodiratime,errors=continue,barrier=0,nobh,data=writeback,noauto_da_alloc,discard)
We can now boot a cloned Neutrino V2.8 GT ROM from SD card, and/or save the modified boot image in a safe, visible location on SD card to configure dual boot (please see: http://forum.xda-developers.com/showthread.php?t=1645344 ). Or, we can roll the modified image into a flashable zip for a standalone boot push.
Standard disclaimers apply. In short, I am not responsible for any harm you or your phone may incur by using any or all of this material.

Many thanks to the Android Community Effort ( http://android-dls.com/wiki/index.php?title=Main_Page ), and to my friend and xda member ghost_og for his “mkbootimg” command-line fix that made boot image repacking work for Atrix.
Boot modifier script: modify-bootimg-atrix.pl includes logic to search both init.rc (Blur) and init.olympus.rc (CM) in ramdisk for ROM filesystem mounts.
Hi,
If you look at my Gobstopper for 2.3.6 I do exactly this kind of thing. I unpack the boot image into kernel and initramfs, modify init.rc, package it up again and flash back to boot. The binaries and source are included if you want to take a look.
Cheers!
Is it possible to modify partitions numbers? because i use different partitions because of webtop2sd and swap partition?

There is nothing Bell specific to it, static linked binaries so no rom dependence. It doesn't do anything about multiple command lines, no, the normal boot/recovery images have any at all, let alone multiple ones.
Cheers!
Is that right?
"5. Boot to fastboot and connect phone to computer
6. fastboot flash boot-repack.img
7. fastboot reboot"
Because my output is like this:
[email protected]:/home/gtmoraes/AtrixCM9/android-sdk-linux/platform-tools# ./fastboot flash boot-repack.img
unknown partition 'boot-repack.img'
error: cannot determine image filename for 'boot-repack.img'

and, of course, the boot-repack.img is in the same folder of fastboot

I've tried fastboot flash boot boot-repack.img. It softbricked
Reflashing the original boot.img de-bricked it without a hassle. Guess your solution is not compatible with Morrisoft CM7 ROM

Soft-brick is usually caused by one or more of the following:
1. The three ext partitions required to host ROM on SD card either do not exist, are not big enough or are corrupt.
2. The three ext partitions exist but no ROM is installed
3. ROM is not compatible with phone
4. User does not wait long enough for phone to boot after installing ROM. First boot usually takes 3 to 5 minutes as the phone is building cache. Subsequent boots should not take longer than a minute with a Class 4 or higher SD card.
And yes, the boot command should be: fastboot flash boot {boot-image}

hi, the size from my original boot is 8 megas, after unpack and repack the size is 4.8 megas, and does not work, my boot is from motorola xt928, did you know why change the size,,thanks
Using CM10 from SD Card (Nottachtrix on internal)
For anyone looking to run Nottachtrix (or other rom) from internal memory and CM10 from external. You'll run into the same problem I did. The init.rc and init.olympus.rc files don't contain the partition information. You need to update the fstab.olympus file in the boot.img. I've attached mine for comparison. (note, after repartitioning my SD Card several times I ended up with a phantom partition (mmcblk1p4) therefore my data is actually on mmcblk1p5.
SD card partition sizes:
System: 340mb
Cache: 700mb
Data: 1.25gb
Additional notes about my partitioning experience:
The DD command in linux (and ADB) copies the entire partition exactly to the SD card's partition, therefore you lose space if you leave it this way. I used DD, but then used fsarchiver to backup all of the sd card's partitions, repartitioned the card again, and restored the partition info with fsarchiver. This made my SD card a lot cleaner and avoided wasting any space.
Everything's running great now. Thank you everyone who made dual booting possible!
Would this tool work on Desire HD?
Need some help. I pulled the boot.img created from ROM1 using copy-boot.img (until step 5 here) and when I ran modify-boot.sh on it, I got the below message:
Unpacking boot image...
Found a secondary file after the ramdisk image. According to the spec (mkbootimg.h) this file can exist, but this script is not designed to deal with this scenario.​
So, I got the boot-NottachTrix-1.3.1-att-sd-ext.img file from this thread and fastboot flashed it, thinking it is already modified, but my phone didn't boot. Then I tried running modify-boot.sh on it and then realized that it has a binary that won't run on mac.
Could someone tell me if I am on the right track with the 2nd steps above so that I can get hold of a ubuntu machine? I tried running it on a puppy linux livecd and it didn't work.
Why didn't the first step work? Is the boot.img created by the copy-boot.sh not in the right format?
Update: I forgot to mention this, but I have NottachTrix 1.3.1 installed on emmc but the size of the boot.img extracted by copy-boot.sh doesn't match that of the one attached to the above link. The one linked is size 3440640 while the one copy-boot.sh created is of size 8388608. For now, I fastboot flashed the later and got back into ROM1. I meanwhile got a livecd boot of ubuntu and ran modify-boot.sh on the one I downloaded and it created boot-repack.img successfully, but I had no success booting with it either.

I have a newer thread: Dual Boot Atrix: Simplified and Standalone: http://forum.xda-developers.com/showthread.php?t=2124668
which presents my own custom standalone tools to do the following:
Partition SD card
Copy ROM from EMMC to SD
Flash boot image via Atrix Boot Emporium
Flash another ROM of choice to EMMC
No computer required.
On first boot, elapsed time from power-up to welcome screen can be several minutes --- especially for larger ROMs --- as the system is building cache.
Hope this helps

Thank you very much! I was able to directly go to the step 4, since I manually copied the partitions already and after verifying that I could boot into the sdcard, used the steps in the "Configuring Dual Boot" thread to get it switch between the two.
It looks like my sdcard is too slow to run android from it, so I will have to find another faster card

[GUIDE] Downgrade Zenfone 2 Laser to any official firmware

I have discovered multiple ways of downgrading ZenFone 2 Laser out of which two methods proved out to be easy and reliable. Both methods have been tested and are working.
Method 2 doesn't require root while method 1 needs root access.
Pre-requisite: Stock firmware zip file. You can find download links from index thread for all variants.
WHILE THIS GUIDE HAS VERY LESS CHANCES OF MESSING UP YOUR DEVICE, HUMAN ERROR CAN ANYWAY HARM THE DEVICE. I AM NOT RESPONSIBLE FOR ANYTHING YOU DO TO ANY DEVICE. YOU ARE DOING THIS AT YOUR OWN RISK
METHOD 1: Requires ROOT-
Short instruction:
Some users say you can downgrade by renaming the OTA zip to correspond to a higher version but that will NEVER work because the update script has this line
(!less_than_int(1457089250, getprop("ro.build.date.utc"))) || abort("Can't install this package (Fri Mar 4 19:00:50 CST 2016) over newer build (" + getprop("ro.build.date") + ").");
Click to expand...
Click to collapse
The recovery reads ro.buid.date.utc value from buid.prop. If the value is less than the value in updater-script (like the value highligted in above quote) any recovery will not flash it, neither stock nor custom. Just increaase the value of ro.build.date.utc (in build.prop) to any value higher than the value in updater-script and then flash the zip via recovery.
Detailed Instructions:
1. Open updater-script from the firmware zip. It will be found in /META-INF/com/google/android inside the .zip
2. look at the first line (!less_than_int(1457089250, getprop("ro.bui....
3. The value 1457089250 is taken as an example, your updater-script may have a different value. Keep a note of this value.
4. Install any root file manager like ES file explorer (if you dont have already)
5. Goto /system (the system folder) using the root file manager. Grant root access if prompted
6. Open buid.prop file as text and look for the line "ro.build.date.utc=1446585430"
1446585430 is taken as example, your phone will have a different value.
7. Now increase this value in build.prop to any number greater than the value you noted from updater-script
for example, if my updater-script has 1457089250 this value and buil.prop has 1446585430 this value, I will simply change the value in build.prop to 1546585430 or 1448585430 or 1457089251. Any number greater than 1457089250 will work in my case.
8. Now reboot to recovery (vol down + power)
9. Select "apply update from external sd card" select your firmware zip file, and then select yes to flash. It will take 5-10 min
10. (optional but recommended) Wipe factory/data . If you don't do this, you will see the annoying "Android is upgrading.." screen which takes around 30-40 mins to reach home screen.
Method 2: Without root, requires computer
Short instructions:
As I mentioned earlier, recovery reads "ro.build.date.utc" But you can bypass this check by erasing system partition.
Just do
Code:
fastboot erase system
from fastboot mode and then flash the zip from recovery
Detailed Instructions:
1. Install Asus drivers to your computer. (link in index thread)
2. Download adb_fastboot.zip and extract its contents
3. Reboot your phone to 'bootloader mode'. To do this turn of your phone completely. Hold "volume down Up" button and then press and hold power button. Release power button after Asus logo appears and then release volume down button. Your phone is now in bootloader mode.
4. Connect your phone to pc via a reliable usb cable. Look at your phone screen. It should display "Fastboot mode!"
5. Now go to the folder where you have extracted all the files. Holding down shift key, Right click on any point on white screen. Then click on 'open command window here' from the menu that appears. Command Prompt will open now
6. On command prompt type
Code:
fastboot devices
and hit enter
and check if it is detecting your device.
7. Then type
Code:
fastboot erase system
(this will erase your current OS, you are warned!)
8. After it is done type
Code:
fastboot oem reboot-recovery
to boot into recovery mode
9. Select "apply update from external sd card" select your firmware zip file, and then select yes to flash. It will take 5-10 min
10. (optional but recommended) Wipe factory/data . If you don't do this, you will see the annoying "Android is upgrading.." screen which takes around 30-40 mins to reach home screen.
Successfully downgraded to 1.16.40.763 from 1.17.40.1234 without root

Failed to mount/asdf.
So i like to flash the lolipop recovery while iam on the marshmallow and then do apply update from sd card. I like to go back to the 1.13 lolipop firmware
Is it possible to to flash the lolipop recovery while iam on marshmallow. If possible. Help me how to do that

"Failed to mount /asdf" error is harmless you will get that error even on latest twrp. You can ignore the error and use the MM stock recovery like normal. Recovery will do its job it can format, install updates, clear cache and everything, you just need to ignore that /asdf error
But you can use any stock recovery from any firmware version lower than or equal to your current firmware version. Drawbacks: You cannot apply update to MM OTAs if your recovery version doesn't match the current firmware version.
Going back to stock 1.13 is a bad idea. I would recommend you to stay on MM since it has many performance improvements.
But still if you want to go back to lollipop, consider downgrading to the last lollipop update i.e. v1.17.40.1531

Going back to stock 1.13 is a bad idea. I would recommend you to stay on MM since it has many performance improvements.
But still if you want to go back to lollipop, consider downgrading to the last lollipop update i.e. v1.17.40.1531

I got a 412 mb ota update some days before. I downloaded it. Apply it for proceed. Then it start checking system as usual phone restarted. But update did not happened. Instead this same error show up. Then i can only reboot system. Got an update failed message.since that when i check for updates iam not even getting any. May be it will be solved by a factory reset .but even if i get an ota. The update wont proceed .because the recovery wont allow me to do that
And also that wipe cache partition also results the same error .so without solving this error i cant update to the latest MM too :/ .
In my experience, the most reliable method is to
extract the recovery from the version of stock ROM you want to upgrade or downgrade to
Flash that recovery with fastboot
Wipe /system in fastboot
Reboot to recovery and update with the stock ROM .zip
Or
Even easier, use Sziraqui's fastboot ready .IMG files and just flash them via fastboot.:good:

The recovery is included in the stock ROM zip file. Extract the zip and you will find it inside.
Presumably if you want to flash the stock ROM you have already downloaded it?

I found out that recovery for each firmware is available here. You should use a desktop browser to use this website.

Thank you.
Can ZE551KL use the recovery.img from ZE550KL? My ZE551KL has the extra 1700(AWS) band.
Please where are you guys downloading your stock rom from?
The stock zip is NOT flash-able like a custom ROM .zip. That's not how it works. If the Roms you have are custom recovery flash-able, they are not the OEM rom, they have been modified.
All the Roms I have come with a recovery.img file...
Then again if I have to explain how to use fast boot to flash the recovery, there is a good chance you shouldn't be messing around with fast boot.......

Can anyone explain me detail. How to flash recovery only. My bootloader is not unlocked. Someone said that i need to unlock bootloader to flash the stock recovery

You don't need to unlock bootloader for flashing stock recovery that you downloaded from the above mega drive.
To flash the recovery.img (or any .img) You need to have Adb and fastboot files in your pc as well as Asus Zenfone drivers installed
All info and downloads for adb and fastboot can be found here
Search and download Asus ZenFone 2 laser drivers.
Once you have your pc setup with these tools,
With Administrator priveleges, locate the folder where adb.exe and fastboot.exe files are present. Hold down shift key and right click on that folder and select "open command window here". Then reboot your phone to fastboot mode [power off, hold vol up +power, release power when logo appears]
Connect your device to pc.
Type the following command on cmd
Code:
fastboot devices
Output should be something like this
Code:
FCAHSJSJJAKAK fastboot
This command will check if your device is connected or not
If output is blank, device is not being detected.
To flash recovery.img, copy the recovery.img file to the same folder where fastboot.exe exists and then type
Code:
fastboot flash recovery recovery.img
Output is easy to understand, if it says [OKAY] then flashing succeeded
Tried downgrading ze551kl by fastboot erase system then installing .zip from Asus website (via sdcard). All of the Asus updates except the earliest fail with 'fota return code 403'.
1.14.40.550 installs ok but then boots (gets as far as displaying the wallpaper), gives an error message in german (looks like 'android media process stopped') and goes into boot loop. Anyone seen this before?
Also, any way to build a recovery.img from the Asus update files?
invalid boot image whenever i flashed stock recovery,any one know why ?
What i do is flash the stock recovery and flash relock bootloader.

I think OP needs a small correction to enter into FASTBOOT you need to press volume up and power instead of volume down and power buttons

There are many ways to bring your phone to life. But I can suggest this;
- Extract boot(if necessary) and recovery .imgs from a full rom(which one you want) via http://forum.xda-developers.com/showthread.php?t=2433454
- Flash them by adb commands
- Put the update.app file in your sd card and start the update by 3 button way
Another suggestion is more simple; use Multi-Tool to flash the stock recovery and that's it.

I don't know actually but md5 errors are usually harmless. But if your recovery is working, just do fresh installation.

Status phone rom I'm wrong. logo only lead to hang on is TWRP, connect PC and Fastboot. but when I rom stock (PLK-L01 C432B270) is successful but unable to reboot the operating system. H7 is due to the security, it's hard to be rescued. I also put it into the service center (not the local machine), they also confused with my H7. I need to find ways to revive it, no matter how well!

Install stock rom via fastboot - what files to install?

Hi all, I want to clean install stock rom via fastboot. I used to do this on my oneplus one a while back. I think that I need to install img files to five partitions (boot.img, recovery.img, system.img, userdata.img and cache.img). Are there any other files that need to installed (eg bin or mbn files)?
I think I should be able to get the img files by unzipping the stock rom files. Has anyone tried to get the img files from unzipped stock rom and install via fastboot?
Any help is greatly appreciated.
Thanks
Don't know exactly, but also interested to learn about this!
OnePlus does not provide fastboot flashable roms, the only way to get them would be to update uusing the recovery first and extracting the .img files afterwards, but then you don't need them anymore since you are already upgraded.

The system.new.dat format is not unique to oneplus, but the standard for flashable android zips since version 6 (aka marshmellow). The system.new.dat, system.patch.dat and system.transfare.list are build from system.img while building a rom (aka compile rom from source). This process is NOT unidirectional; you can easily revert it. I'm on linux, so you have to google, how this is accomblished on win or darwin. For linux users:

I was assited with a dev on here named pizzaboy192
He had me for load oem.img through the terminal commands.
He uploaded the oem.zip and he has a special recovery.img file to use to do a proper oem backup.
Here is a quote of our converstation.
After all that i am still not perfect. I used a twrp backup of oreo I found. It is the only way I can load anything on my phone is though a backup/restore.
I can't flash anything, and I can't adbside load anything either.
You can download the twrprecovery file from his post.
"Visit my XDA profile (I'm on mobile right now) and find my post about TWRP for stock. It's a special version I threw together to backup the OEM partition properly since TWRP normally doesn't.
What we're going to do is fastboot boot TWRP (not flash it) and then restore a backup of the Oreo OEM partition using TWRP.
Then fastboot flash all other Oreo partitions. Any Oreo ROM will work just to get you running, and it should take otas too."
next message:
"OK we're going to force OEM onto it.
https://drive.google.com/file/d/1WUw...ew?usp=sharing
That is the OEM partition but compressed. It should extract to a 768MB file (roughly that size)
copy it somewhere on the phone (TWRP should allow you to mount the internal storage as a USB drive, if that doesn't work, try ADB Push and push it to somewhere like \tmp
Then you will need to use adb to do the following (TWRP is broken for ADB and the stuff it spits out to your computer is garbled. I wasn't ever able to fix it.)
type adb shell and it should dump you down into some garbled mess
hit enter a few times to make sure you're at the shell (it's a root user)
load up notepad, paste the following into it and edit it so it shows the right path for the extracted .img file on your phone
dd if=/tmp/oemoreoaug.img of=/dev/block/bootdevice/by-name/oem
Copy that string and paste it into the adb window on your computer and hit enter. It will take a while to process it and then return an error about it running out of space before you hit the end of the file. that is OK (since your partition is too small)
Once it's finished, copy that result and send it to me just so I can have a clear idea what is going on.
Reboot into fastboot, reflash the oreo firmware but skip the line for OEM (it's kinda global, but not 100% but since moto hasn't released any updates since the oreo one and they don't seem to care, who cares as long as it works, right?) and then see if it boots. "
so if you get that to work,
then I was only able to do a restore using this file
MotoG5sPlus_Sanders_Android8.1Oreficial(ByYoungRockTech).rar
after that I did a full backup using Pizzaboys recovery, and now I am able to restore it at anytime.
