[GUIDE] Get Bravia and Music Info working again on ICS with ReLock bootloader

[revan17]

The credit goes to nhoc_huhu for posting this fix and jemju_xps-user for giving more detailed instructions and confirming it works. Please leave thanks for them, I'm just posting detailed, easier to follow instructions.

Things you will gain:
- working Bravia on ICS
- working Download Music Info for Walkman
- root will stick if you had it before

Things you will loose:
- ability to flash custom ROM's requiring unlocked boot loader. Duh.
- CWM recovery. You can get it back using this guide

Steps:

1. Download Walkman_port_few_fixes.zip
2. Clear data for Download Music Info and all Walkman apps, under settings>apps>all
3. With Root Explorer or any root manager; copy CredentialManagerService.apk from the attached zip and paste it to system>app and set permissions. Delete .odex file for CredentialManagerService if you're on a odexed stock ROM.
4. Copy file system>lib>libdrmtestengine.so from the zip and paste it to system>lib and set permissions.
5. Copy file system>lib>DRM\libdrmtestengine.so from the zip and paste it to system>lib>DRM and set permissions.
6. Shutdown and flash stock kernel with Flashtool.

- either use the kernel from the FTF file of the Firmware you are currently using, be sure to not wipe Data(you will loose apps) and System(you will loose root). Uncheck wipe data and check Exclude System.

- OR flash this with fastboot; fastboot flash boot 55.sin. The attached kernel is for .55 firmware. Here is the JB .200 kernel.

7. Relock your bootloader using these instructions.
8. Reboot and it should be working!! It does for me(stock .55) and jemju(XTX v7) :good: :good:

Optional: When I relocked bootloader, my WiFi was broken. Download this and paste it to /system/lib/modules with correct permissions. Reboot and WiFi will be back.

Because it works. Check the pictures mate. The difference is clearly visible. Look at the skin color, the first is BE off, the second BE on.


Sorry if you guys are non-smokers, this pic was the best I had to show BE working.

You can try. Though my personal opinion is that BE2 over BE1 is just placebo..it's hard to tell difference between BE1 on and off, let alone between BE2 and BE1.

I can confirm Bravia Engine Working with this method :good:

I use Bravia Engine 2


Open attachment screen shots in new tabs and compare them

 

[Nepythys]

At long last! It truly works! Using BE2 here. Thank you so much! Really appreciate it!

 

[jemju_xps-user]

anyone can confirm again that b.e. is not working on xtx..because i read this post - http://forum.xda-developers.com/showthread.php?t=2010673&page=8

 

[Nepythys]

I'm on XTX7 and I can confirm it works, both BE1 and BE2

I think it will work, Because, I flash stock .55 , UB to root then I relock and copy DRM ,next i flash BE2....And i can see the diffirence beetween BE1 BE2..., Here image:No Be, BE1, BE2

 

[nhoc_huhu]

I think the rom base on stock will work.....i tried the other rom (skudo v3) base on Stock and it still work..

Yeah, a slight delay was always there, from what I remember. But that's OK, the delay makes it easier to see which parts of the image are enhanced.
