[Kernel] SEtweak - insecure ADB, ext4, NTFS, overclock, USB OTG - updated 24th July

[Blagus]

First custom kernel for Xperia Play, built from SE's sources.

SEtweak is based on Sony Ericsson 3.0.1.A.0.145 sources. You need 3.0.1.A.0.145 FW to eliminate problems!

Donation thread.

Features: NTFS support - still buggy, ext4 support, insecure adb shell, USB OTG, bcm4329 driver included in kernel image (separate module not required).

Future plans:
* USB HID driver to use phone as USB game controller.
* add su binary and Superuser.apk for auto-rooting

Version: RC0 - hopefully all bugs are fixed. If tests show everything is OK, I can move to gamepad HID

Instructions:
* Unlock bootloader
* fastboot flash boot /path/to/boot.img
* To return to stock kernel, use this: http://forum.xda-developers.com/showpost.php?p=14821537&postcount=17

Erm... count me in!

 

[thomassafca]

I wouldn't mind helping at all
It's completly save isn't?

 

[Blagus]

To restore back, make loader.sin+kernel.sin flash bundle and flash it... I think I'll make one just in case...

 

[Logseman]

While you do it, make a tutorial so that we can do that package too, and relay the instructions

Simple... take flash bundle for 3.0.1.A.0.145 FW. Open with zip archiver. Take loader.sin and kernel.sin, open FlashTool, Bundle creation, navigate to extraction folder, take loader and kernel sin images and upload ftf bundle here.

i would love to test this and anything else that won't brick my phone

 

[Blagus]

Uploaded first release... in "stock" folder you have kernel unbrick package - make flash bundle and flash it. I couldn't because in Linux I can't run FlashTool...

 

[Logseman]

I've been able to "run" it through Wine, but it wasn't usable.

 

[Blagus]

Leave that. I'll switch to Windows, now flash this and test it

After reboot in the notification screen it gives the message it's safe to remove the sd card and I can't copy anything to it. Rebooting and trying again.

After reboot it still tries to have you remove the SDcard and it's still not accessible. Also the last_ksmg file seems gone after this second reboot

But kernel works? Can you go to system info and say what does it say under kernel version? Test BT, Wi-Fi, calls, etc.

 

[svenk919]

Was about to flash back the standard stuff. Boot time is impressive btw, from the start of the bootanimation it takes 8 seconds to get to the lock screen (I have a minimal of bloatware, removed most of that but this seems faster then before).

3g data Does work.
calling over gsm does work.
Camera doesn't. (directly gives error in pop-up screen)
When trying to turn on wi-fi it just says error in the button (no pop-up screen)
Bluetooth seems stuck on turning on.

Will test some more in service menu.

Kernel version: 2.6.32.9-Blagus
[email protected] #1



Edit: Service menu says that the camera is not connected when testing the back camera, when testing the front camera it just gives a black screen.

Service menu seems to get stuck when turning on bluetooth to... reboot needed.

SD card status in service menu is unmounted.

 

[Blagus]

Thanks a lot! Exactly as expected, Wi-Fi and BT problems... luckily, basic phone functionality works... I'm really happy about this, plus the satisfaction of seeing "[email protected] #1" in kernel build

Edit: after full test, reboot the phone and cat /proc/last_kmsg > /data/local/tmp/log.txt, then adb pull /data/local/tmp/log.txt and put here.

Flashing files back but it seems to be stuck at flashing kernel.sin:

For like 4 minutes now

 

[Blagus]

Hmm... I think I've packed some wrong kernel image... do you have 2.3.3 flash files on your PC - either in ftf bundle, or you upgraded via SEUS?

 

[svenk919]

Took the kernel.sin and loader.sin from the UK .145 firmware and made a new tft with that. All seems to be working now

Attached the working stock kernel and loader ftf for others.

Edit: after flashing back I could copy the file to my SD card. Will PM it.

 

[Blagus]

Did you get last_kmsg from my kernel?

 

[Logseman]

cat /proc/last_kmsg > /data/local/tmp/log.txt

Before I flash, where should I execute this? On a terminal emulator in the phone?

Rebooting in Windows to try. Svenk, you're the man!!

 

[svenk919]

Flashed your kernel again but now there is no last_ksmg after first boot. Also adb can't find my device, usb debugging is enabled :/

Root explorer works though. Will try another reboot.

Edit: still not there after reboot is the normal ksmg of any use?
