CF ext4 Manager - all choices are greyed

Hi, I tried to apply ext4 lagfix via CF ext4 Manager (CF-Root-ext4-v1.3-Addon.apk) , data was converted successfuly, system was not converted due not enough free space, which is normal as Chainfire said.
Please note that when first using the tool to convert, you will probably notice /system is not converted. If this happens, it is because /system does not have enough free space for the extra space overhead of ext4. You will need to free up some space on /system before the conversion will succeed.

Running 2.3.4 JVQ stock firmware with CF root.
But after reboot ext4 app have all choices grayed, so I cannot convert system or any other partion to ext4 or back.
It show "No rfs/ext4 partions found" and "unknow ,0.0MB, 0.0MB total"
Any tips appreciated. Thanks in advance
Roman

Which kernel are you running? Try changing kernel eg: Semaphore or galaxian. Then do a wipe cache and dalvik cache

Runnig CF-Root-XX_UNK_JVQ-v3.7-CWM3RFS on stock JVQ without other changes.
Thanks for advice
Problem is, that many kernels have logging disabled, I need logcat, ddms for developing
EDIT: Flashed semaphore, there is greenscreen while lock/unlock screen(minor issue),but other things seems fine, thanks!

semaphore has logging enable script
Quote :
"In order to control voodoo sound and BLN you have to download Voodoo Control and BLN control applications respectively from android market.
The max CPU frequency is by default 1Ghz.
You may use applications like Voltage Control or Pimp my CPU to control OC/UV.
In order to load various modules of the kernel copy the respective script from /res/scripts to /system/etc/init.d directory and give the script executable permissions. This is optional. It is needed only if you want to use this functionality. The scripts:
- enable_conservative (load conservative governor module)
- enable_cifs (load cifs module)
- enable_netfilter (load netfilter modules for firewall or WiFi, USB tethering)
- enable_tun (load tun module)
- enable_deadline (load the deadline I/O scheduler module)
- enable_binfmt_misc
- S05_enable_oc replaces enable_ocuv since 1.6.0 (enable overclocking)
Other scripts:
- enable_sm_cold script for SpeedMod cold preset
- enable_sm_warm script for SpeedMod warm preset
- enable_sm_neutral script for SpeedMod neutral preset (please note that this is enabled by default)
To enable logcat run the enable_logger script in res/scritps and reboot your phone."

Hope this helps.

Tips
How to change sleep/wake options:
The options for sweep2sleep, sweep2wake and doubletap2wake:
sweep2sleep: 0 - disabled, 1 - enabled, both directions, 2 - enabled, left->right only, 3 - enabled, right->left only
sweep2wake: 0 - disabled, 1 - enabled, both directions, 2 - enabled, left->right only, 3 - enabled, right->left only
doubletap2wake: 0 - disabled, 1 - enabled, full screen, 2 - enabled, bottom half screen, 3 - enabled, center down of the screen (hope you get it)
To change the options, put a script in /system/etc/init.d:
Code:
#!/bin/sh
echo "0" > /sys/android_touch/sweep2sleep
echo "0" > /sys/android_touch/sweep2wake
echo "0" > /sys/android_touch/doubletap2wake
This setting disables all the sweep/wake options
Code:
#!/bin/sh
echo "1" > /sys/android_touch/sweep2sleep
echo "1" > /sys/android_touch/sweep2wake
echo "2" > /sys/android_touch/doubletap2wake
This setting enables sweep2sleep and sweep2wake, and enables doubletap2wake bottom half of the screen

How to use fastcharge:
If you charge your phone via usb (from your computer) then it will only charge at 500mA even while most usb ports are capable of supplying 1000mA. Enabling fastcharge will allow your phone to charge at 1000mA via usb.
!!! Warning: you must be sure your usb can supply 1000mA !!!
Fastcharge is disabled by default. You can enable it in 2 different ways:
1. Writing a 1 to /sys/kernel/fast_charge/force_fast_charge. You can do this with a text editor, or with a script in init.d (see above)
2. Or you can simply install an app. I tested Fast Charge by Mathew Winters and Fast Charge by Chris Conley, both worked.

To hard? Use this app by Ufonek: Kernel Settings
A word about governors:
Some governors lower the frequencies to fast. For example, when I play angry birds when using lulzactive, the phone laggs a lot. This is, however, not the fault of the kernel, but the fault of the way the governor is tweaked. It is the price you pay for the better battery life you have. If you want to do something about it, tweak your governor, there are a lot of tutorials about this.
Don't come here complaining the phone laggs, and that I should fix it, I won't, because I can't. Everyone has his own preferences, and if you can't live with this, then I recommend you use the ondemand governor.

Compilation instructions
Instructions for compiling the kernel yourself.
Prerequisites:
1. A linux computer
2. Basic bash knowledge
3. ~120 MB free space
4. The android-eabi toolchain:
git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6 for 4.6
(use darwin-x86 instead of linux-x86 for mac)
And then add it to your $PATH (You need to have the arm-eabi-4.6/bin folder in your path)
Instructions:
1. Download the kernel source
2. Open the cmdline and cd to the directory with all the files (Documentation, arch, block etc.)
3. type: make dummie_z4u_defconfig
4. type: make menuconfig
........A menu will open, and you can change some settings. If you want everything to be the way I built it, then skip this step.
5. type: make
The actual building will begin.
Troubleshoot:
If you run into a python problem, you might want to change, in android_kernel_htc_z4u/scripts/gcc-wrapper.py this:
"#! /usr/bin/env python" into "#! /usr/bin/env python2", credits @svalo
If the building succeeds, then you will find the file zImage in arch/arm/boot.
Next step: turn the zImage into a boot.img
1. Download imgtools, and add it to you $PATH
2. Download my boot.img
3. Open cmdline, cd to the directory containing boot.img and type: unpack boot.img
........You will end up with: ramdisk.cpio.gz, ramdisk and zImage (and the boot.img that was already there)
4. Replace the zImage with the zImage you build earlier (arch/arm/boot)
5. Rebuild the kernel:
Code:
repack_ramdisk ramdisk initramfs.cpio.gz
mkbootimg --kernel zImage --ramdisk initramfs.cpio.gz --base 0x3b00000 --cmdline 'no_console_suspend=1 console=null' -o new_boot.img
You will now see a file called new_boot.img, containing your own kernel, which you can install the very same way
Good luck:good:

Note that -O3 does not work for the kernel, at all, and never has. You can set it but it won't do anything. The compiler will still use -O2, because all the parts where performance matters are written in assembly or through GCC-specific extensions already. There is nothing that automatic code optimisation would improve. Meanwhile -O3 enables non-safe options that can result in imprecise calculations, which can lead to disasters in things that are as important as the kernel. So you should disable that.

No, you don't need to flash the kangbang kernel. This is a replacement of the kangbang kernel, for 1.32

Replacement?? That means if i flash the boot image i'll have the kernel installed?

Dual SIM doesn't have the 1.32 update, so i don't think this kernel would work on the dual sim version.

[KERNEL][G800F][exynos][G800FXXU1*][TW Only][MM Only]Custom Kernel

hennymcc:
Important notice:
- You flash this image at your own responsibility. I am not responsible for any damage that might be caused by flashing this image (bricked device, lost data, ...)
- Flashing this kernel image will trigger the KNOX counter, so your warranty will be void.
- The image is only for S5 Mini SM-G800F (Exynos)
- The kernel is not tested well. It might be instable, crash your device, drain your battery, or even might damage your smartphone (e.g. if an OTG device drains too much power)
- Backup your data before flashing and check if the original firmware is present (e.g. at SamMobile)
Click to expand...
Click to collapse
Side note: Tripping KNOX counter might break some Samsung applications even after a factory reset. This might be due to secure storage(which is fixable), but for now be cautious if you depend on these features! This image will likley damage the Qualcomm variant of the S5 Mini, do not flash if you have a G800H!
Hello! :laugh:
I've been working on a custom kernel for a while for personal use but I thought some of you might like it.
Current feature list:
Patched to Linux 3.4.113
Fading LED notification (default disabled)
Added row I/O Scheduler
Added zzmoove CPU Governor(with temperature export)
Added PIE network scheduler(supposed to reduce latency, default disabled)
DriveDroid support
Universal Control Interface[UCI] (use the Synapse app to configure)
USB OTG
Boeffla sound engine (Only configurable via Synapse! default disabled)
Powersuspend with LCD panel hooks
1.5GHZ clock speed on processors with revision 2 and above
Double Tap 2 Wake
Voltage Control
MDNIE Hijack
F2FS Support
Haptic Feedback for soft keys
Compiled with Self built Linaro 5.3 toolchain
This kernel is currently only designed to work with the corresponding TouchWiz ROM and likely won't be able to boot custom ROMs. KitKat/Lollipop TouchWiz is also not supported!
If you have any questions about the included features (how to enable, what they do) you may ask in the Q&A until I update the thread.
About 1.5GHZ clock speed
So, as it turns out, Samsung had already done the work to push the 3470 to 1.5GHZ. The frequency tables were already there and all that needed to be done was to remove a soft limit set on it and voila! 1.5GHZ! The catch is that these tables only applied to the second revision of the SoC and above.
Possible reasons why Samsung set the limit:
The S5 mini comes out with both the older and newer revisions of the 3470 and Samsung wanted to avoid getting in legal trouble for selling a higher clocked phone as the same product
The higher clock speeds legitimately can damage the phone
As I don't have multiple S5 Mini's at hand I can't prove the first point, but the second point is more likely true. If you don't feel comfortable with the higher clock speeds you may lower the maximum to 1.4GHZ via Synapse, but the default clock is always 1.5GHZ due to the way in which the frequency controller works.

OTG switching
Credit to tobigun for the original code (I actually attempted it at some point but failed miserably).
Execute the commands in a terminal:
Turn on OTG
Code:
su -c echo OTG > /sys/class/sec/switch/otg_cable_type
Turn off OTG
Code:
su -c echo USB > /sys/class/sec/switch/otg_cable_type
(Haven't touched Synapse in forever, cannot make sense of it anymore, so no Synapse switch soz)
Synapse Issues
I had some trouble with colour choosers crashing Synapse under specific conditions. If Synapse keeps crashing when picking colours for MDNIE, please try the custom build available in the downloads section of this project.
IF THE DEVICE IS CRASHING WHEN USING SYNAPSE, THEN YOU HAVE LIKELY SET UNSTABLE SETTINGS! SYNAPSE WILL NOT PREVENT THIS, SO PLEASE BE CAREFUL WHEN CHANGING SETTINGS!
There are two ways to recover:
- Use your recovery to delete Synapse's data folder
- Factory Reset your device (Only in extreme cases)
Using PIE netsched:(likely not working with Android at this point in time)
Run following in root terminal or as init.d script
Code:
tc qdisc replace dev wlan0 root pie
tc qdisc replace dev p2p0 root pie
tc qdisc replace dev rmnet0 root pie
ZZMoove and profiles:
The zzmoove governor is highly recommended. It can be set to various profiles to mimic the benefits of various other governors. It'll even ensure the device doesn't overheat!
The profile can be set by setting the "profile number" tunable in Synapse to one of the number values mentioned here. Setting it will change a bunch of other tunables. You'll need to restart Synapse after setting it and save the changes for future application.
Notes on DVFS
Samsung's DVFS feature in their TouchWiz ROMs seems to get a bit shouty when anything other than the "interactive" CPU governor is active. It could also be the cause of rare kernel panics relating to CPU frequency tables(frequency controller expects something from the governor, governor doesn't deliver, panic). Since it also seems to cause a couple other unrelated issues, I'd recommended simply disabling it altogether(the easiest way being via Xposed)
Double Tap 2 Wake
This feature allows you to wake the device by double tapping on the screen while it is off. NOTE:Deep sleep is near totally inhibited while this feature is active, this means extra battery may be consumed. On a tweaked ROM you'll get 2-3%/hr on full standby, on non tweaked you'll get about 4-5%/hr, please keep this in mind while using the feature! Android OS suspension should be unaffected. The feature disables itself when a Samsung branded flip cover is closed, including S-View covers(no double tapping on the window). The feature makes use of the light and proximity sensors in order to detect whether the device is in a dark enclosed place (eg. A pocket) and disables itself in these situations as well in order to prevent accidental wakes (though that may still happen...)
MDNIE Hijack Example
Profile based of iPhone 6+ screen:
R: FF 00 00 - G: 12 FC 12 - Bu: 00 00 FF - C: 12 FF FF
M: FF 00 FF - Y: FF FF 00 - W: FF FF FF - Bl: 00 00 00
Feel free to post any other nice looking profiles you find
Init.d in Lollipop
I did not add Init.d support when building the Lollipop variant's ramdisk. Instead, /su/su.d should be used to run boot scripts. The functionality is exactly the same as the old Init.d.
Haptic feedback on soft keys
In order to avoid conflict with ROM side solutions, haptic feedback is disabled by default. It can be enabled via the following command which can be run as a boot script (eg. in /su/su.d). Command must run as root.
Code:
echo 1 > /sys/class/misc/abov_touckey/vibrate
NOTE: Above "touchkey" was misspelled in code. It should be fixed in a future update. Sorry for any inconvenience
still not fixed lol

Awesome, thanks !
Installed it and testing now

After a few days of testing !!! All I can say is, Great Kernel :good:
Good performance, great battery life
No issues so far.:highfive:

Working fine on G800FXXU1AOE3

And works great on G800FXXU1AOG2 too.

Again big Thanks Curtis ! :angel:
kernel is damn good.
Games running very fast for me with the new updated kernel
The 1.5Ghz CPU overclock is .. awesome
For additional gaming performance you can lock the GPU Frequency like this:
Shell command:
cd sys/module/mali/parameters
echo 533 > mali_dvfs_control
thats it, gpu locked to 533 mhz. Thanks to hennymcc for this commands
for example:
GTA San Andreas running now with maximum resolution+visibility graphical settings
Solid 30+ FPS :cyclops:

Sorry for noob question - can someone show me the exact syntax to enter in Terminal (or procedure) to activate OTG ? I don't seem to figure it out .

Thanks Curtis , but something is wrong in my case . It doesn't work and I don't understand why . After running the script , I granted the root access
, everything seemed to be ok , but nothing happens when I connect and USB key which is recognized in my S4 phone .

Does anything else work? OTG also gets reset on boot, maybe it needs to be in an init.d script. I'll admit, I don't have an OTG cable to test, perhaps I should get hold of one, but the code definitely creates the right behavior (exactly the same as the other OTG kernel around here actually). Maybe switchable isn't the right way to go about it and OTG must be enabled permanently. I'll have to look into this, but in the meantime could you perhaps test with the other OTG kernel and see if it works? Also, the stick maybe might not be automatically mounting. Run "mount" in a terminal and see if it pops up. Apologies for the inconvenience.

Attached is a build of the kernel with OTG enabled on a permanent basis. If you would not mind, could you test to see if it works? If so it will be done this way in future release, if not I will have to have a good look at any related code...
(P.S, sorry for the wait, my dual-boot was giving me issues)

Yes , OTG works with this kernel . Great !
Note that after flashing, another reboot is needed to have the usb key properly mounting and poping up the file explorer with the key's content on connection .
Thanks !

New Version!
New version of my custom kernel released. Now includes Double Tap 2 Wake.

Is it possible to add voltage control to your kernel ? thanks .

CPU Voltage control is now implemented. Will work on a Synapse interface and the int and mif buses later today.

New Version!
Voltage control, Linux patches and fixes for DT2W waking up the screen while a call is in progress(sorry 'bout that)

Working great - I achieved good undervolting . Thanks
Hope to see a modified kernel for Lollipop too .

Frequently Asked Questions and Other notes:
Can I upgrade / dirty-flash from Lollipop to Marshmallow?
- You cannot. It must be a clean install.
Can I dirty flash over a previous Marshmallow build?
- Yes.
I thought you said Marshmallow wouldn't work.
- The problem with ART is not solved. The Optimizing compiler backend is producing binaries that crash on the Tegra 2. The Optimizing backend is the new default dex2oat compiler in Marshmallow. The Quick compiler is default backend in Lollipop. It is still in the Marshmallow source so this ROM is using the Quick compiler backend.
SELinux enforcing mode
- The default SELinux mode is permissive mode. The Set_SELinux_enforcing.zip will not work with Marshmallow. That script was setting a system property to toggle SELinux early on in boot. Google has removed the use of this system prop so that method won't work anymore.
- For now you can find some app on F-Droid to set the SELinux mode after boot. It's not ideal but it will do until some better solution arises.
Doze
- This device does not meet the hardware requirement to support Doze.
Themes
- Marshmallow supports RRO (Layers) themes. I will not add CM-12 themes, CM-13 themes, or any other theme engine.
HD video playback issues and Camera issues.
- The video and camera stack are proprietary NVidia software. This means there is no chance of fixing bugs within.
Browser crash when downloading files
- Settings > Apps > Browser > Permissions > Enable Storage permission
Google App force close
- Install GApps Pico.
- Google App now uses the NEON instruction set which the CPU on this device does not support. The pico package does not include the parts of GApps which use the NEON instruction set.

Problem reporting steps:
Got an error? Is something not working for you?
I cannot see what your problem is from here. Save and upload the system logs from your device so that I can see what happening on your device.
How to save system logs:
Root the device by installing SuperSU.
Install SysLog.
Reboot the system.
Reproduce the problem.
Open Syslog app and save the Kernel Log and Main Log.
Send me the log files stored in /sdcard/Syslog.
Share the files on Dropbox or another similar site.
Then PM me a link to the files. Please describe exactly what the issue is.

Some comments to start off.
The ICS audio HAL is not working right in Marshmallow and I think I'd rather try another run at getting the rest of the stuff in the open souce HAL working rather than keep trying to find hacks to keep the old blob alive. Recall that only voice calls and dock audio are not working with the open source audio HAL.
- Voice calls are just passing off audio to the Samsung cellular blobs so I don't think it's that much of a stretch to get working. But this will have to wait until cellular stuff is working in the first place.
- I found some patch for Samsung dock audio. It looks like it might apply to this device as well seeing as it seems to have a similar dock implementation. The patch is in the ROM already so that needs testing.
Cellular probably won't work for at least the first few builds. Other devices on M with a similar cellular radio needed a few new patches to get it working on M. I have put in the patches from L but we will have to trial and error what is needed for M based on other devices as a reference.

Thank you!

I know it's early on, but do you have any expectations as to how well it will run compared to previous Android version?
I appreciate all you've done, but mine never ran that great on the newest roms. It is passable and I appreciate it though.

thank you very much for betting on this tablet , and download and I'll try ... I'm sure you will be able to tune it as we did with lp...

The OS appears to perform the same as Lollipop. It's a four year old device. There is nothing that will make it run as well as a modern Android device. You could try setting animation times to zero and set ro.config.low_ram=true.
For Marshmallow I have added L2 cache improvements in the kernel that improves RAM speed benchmarks. That's around 1k score in Antutu.

I understand that. And again I appreciate it. I was just curious what the performance level was. I expected at best it might be similar, but more likely it would, as is typical, use more resources.
I never expected much from my Tab. Finding your ROM was an unexpected surprise. I will try those tweaks. From all of the posts I read, I got the impression that many other tablets ran better than mine. I know fully well that each tablet is different and I don't blame you or the ROM, just my tablet.

Thank you for keeping this Mastodont alive. I will be doing the switch soon enough... I have been following and installing your Lollipop releases for quite a while now and appreciate very much all the time and effort you have put into these projects...

Definitely wasn't expecting this tbh. You're doing a damn great job at keeping this tab alive decatf. Thank you for that.

Mmmh, I just did the following steps (coming from your version of 5.1.1) :
1) Installed TWRP-2710 from previously installed TWRP-2610
2) Rebooted into 2710 Recovery
3) Full Wipe
4) Install Android 6.0 ROM
5) Install OpenGapps (nano)
6) Install SuperSU 2.52
7) Reboot
Now the P4 is stuck at the Samsung boot logo, so it does not boot up.
Any ideas what I did wrong?
Regards, mistersixt.

Me too, ive installed twrp 2.8.7.0. Full wipe, install android 6 rom (P4) and use openGapps (pico), install superSU beta 2.52.
My P4 is stuck at samsung boot logo

Anyone able to install the rom successfully?
Anyways thanks decatf for all u have done for our device!

maybe don't use OpenGapps Pico?
on different devices, had issues with OpenGapps Pico versions;
especially on 5.1 and 6.0, pico may be -too- light?
I've had success with slim gapps zero on different devices;
size is similar to OpenGapps nano.
- maybe try WITHOUT any gapps?
- assuming it works, try Open nano, or slim zero?
i'll try myself and report later if I can
cheers

I haven't read -too- thoroughly,
but in addition to the 'regular' supersu beta (currently 2.52),
chainfire has a separate "WIP" thread where, at least check,
2.61.. for Marshmallow+.. systemless?.. discussion is still in the 2.52 / beta thread
a) link to the WIP thread: http://forum.xda-developers.com/apps/supersu/wip-android-6-0-marshmellow-t3219344
b) that said, maybe for our system , 2.52 may be more appropriate?
can anyone compare?
c) hmm.. more reading.. may want to stick with 2.52 for now,
until 2.62 is ready (currently 2.61, but with planned features/fixes for 2.62)
cheer

Same thing, just did another full wipe and installed the p4 ROM only (no gapps, no supersu), and it is still stuck at the Samsung boot logo.

It works on my p4wifi. Somebody with an actual p4 needs to try booting it then reboot directly into TWRP and grab the last_kmsg.

more info..
before the error message (in red), a message about mount/symlink:
mount: failed to mount /dev/block/platform/sdhci-tegra.3/by-num/p4 at /system: Device or resource busy
symlink: some symlinks failed
?

It might just be some kernel cmdline options I missed. The reason it boots on my p4wifi is because I'm testing it on multirom which passes off some cmdline options from the host ROM so the problem was not apparent due to that.
Just install the ROM then the kernel. And the rest of the stuff as usual.

Any KVM enable kernel??

Is it possible to enable KVM on this powerful device?
I can't enable kvm There is a patch Here: https://github.com/sleirsgoevy/exynos-kvm-patch
But I can't apply the patches since every time I boot with kvm There is no /dev/kvm
Thanks
