Bravia Engine 2 BRING BACK after unlock bootloader

subha7082 · Apr 23, 2014

After unlocking the bootloader bravia engine 2 on albums did not work.only if there is a TA backup then you can recover DRM keys and make BE2 working again.

This mod is for them who has forgot to backup TA before unlock BL and desperated when remembering the real fact.

Now here is the way to revert to stock fully without DRM keys. :cowboy:

:angel::angel:

Instruction

1) Flash 4.1.2 , 4.2.2, 4.3 stock FTF.
2) then flash the boot.img via flashtool.
3) root by flashing update su.
4) flash stock kernel.
5) reboot device.
6) install a root browser.
7) Delete Credential Manager Service.odex from System/app (do not delete Credential manager service.apk)
8) reflash boot.img
9) reboot to CWM
10) flash Bravia_Engine_no_DRM.
11) pull the battery out.wait 10seconds.
12) now relock bootloader.
13) switch on and cheers BE2 working again. :cowboy:

:victory::victory:
14) unroot phone from SuperSU. :laugh:

You can also update your phone via Sony PC companion or from FOTA.Do not use SUS update.then you have to follow instuuctions again for BE2.

NOTE: Get a backup of your sms contacts and DATA stored in phone memory before installation
Please report back if it does not work.

For stock kernel you have to get the FTF of the version you want to flash (4.3 ftf is better).then exclude everything except kernel on flashtool.

this is the link to stock kernel.
if this help hit thanks.

Hey there subha7082 I did flash the stock kernel but after all that when I relocked the boot loader the phone wouldn't start. It would vibrate when I pressed the power power button like usual but the screen wouldn't turn on.I do not get step 8 where it says reflash the boot.img because we already flashed it and it didn't go away after flashing the kernel.

subha7082 · May 23, 2014

okay. i think you didnt use power off after flashing from cwm.you have pressed reboot to system and then pull out battery.

you have to do whole prossess again.

and this time after flashing directly pull out battery and put after 15 seconds or better to go advance>power off

then flash stock kernel

Yes this works! I am currently running stock kitkat as well
With bravia engine 2. I was also able to root using towelroot although you need to install SuperSU separately.
