[QUESTION](P) Bravia Engine unlocked Bootloader. - Sony Xperia P, U, Sola, Go

Hello Today comparete my Xperia P with other Xperia P, with 6.1.1.B.1.75 and see a big difference with Bravia Engine. My phone have ulocked bootloader and the other locked, my Xperia dont work Bravia Engine, i try with Relock Bootloader and nothing, i flash Gingerbread in my phone and works good (relock bootloader) and update to ICS with Update Service and still with problem, Bravia Engine doesnt work. Any solution? It´s normal? I dont know what can i do, i'm sad HELP ME PLEASE

Bravia engine is corrupted on ICS with unlocked bootloader due to removing some DRM. I think, this never will be officialy repaired, because Xperia T has this issue too and it isn't repaired in Jelly Bean .

What about sola?

Bravia Engine won't work on unlocked bl. Also TrackID and downloading music info in Walkman won't work on unlocked bl. You lost your DRM keys forever.

1) there is a relocking bootloader. Tft file which relocks your bootloader only { DRM KEYS WONT RETURN}which will help you to bypass Sonys altered software error while updating it through SEUS or PC Companion n you can update your device without any problem to latest firmware....
2) No performance change is noticed rather the performance wil increase if you using custom roms...
3)it works only for Xperia 2011 device

Hi for now, there are no known ways of rooting the locked Sola bootloader.
There are successful methods for this on ICS but not gingerbread, for now. I have tried so many.
Thanks for replies. Thread moved to the Q & A.
so we w8 ICS or FXP its like a race! xD
I got tired of waiting and crazy rumours so I did it, unlocked myself. I wanted root that much. Plus, I read B4anry explain in a comment exactly how Sony treats locked/unlocked bootloader, depending on what you've done, and I think I'm safe. He knows his stuff obviously!

[Q] Will Zelly Cream rom work on Neo?

Hi, I have a Live With walkman and i use the zelly cream rom (http://forum.xda-developers.com/showthread.php?t=2155803) and a friend of mine saw it and wanted it. The question is since in the post says that is available to all the 2011 Xperias it should work, but it was posted in the Live with walkman section.
So anyone knows if it will work or not?
So, you asked without searching? Cause if you have searched you would have seen that both neo and Neo v is supported(and all 2011 hdpi devices as you already said)

Downgrading your phone it's possible, just get the desired ftf file with the version you want and flash it with flash tool. Now to install this rom YOU MUST be on ics .587
About the second question, i didn't understand what you meant.
what would be the best display settings on zelly cream to get a good battery backup?

Nope nothing related to drm
Flashtool works on locked or unlocked both without any partiality
You might have messed it up yourself accidentally

[Q] disadvantages of Unlocking bootloader?

hi guys... as i was thinking to unlock the bootloader of my XGO, I wanted to know that are there any disadvantages of doing it?
like i read somewhere that after unlocking BL the bravia engine doesnt works... so is it true or just myth? also if there any known downsides of unlocking the BL then plz tell me...
And 1 more thing i wanted to ask that as im using POWER JB rom right now, so do i need to be on stock rom to unlock the BL or can i continue with the power jb rom ?
thanks in adv.

1) The disadvantages are that you will loose bravia engine and you will void your warranty. The only reason you should unlock your bootloader is for installing custom kernels.
You can relock your bootloader via flashtool.This way you will have your warrranty back but you will not get back bravia engine as far as i know because you will loose DRM keys.
2) The rom you are using if for all bootloaders. Otherwise you wouldn't be able to boot system
3) You can unlock your bootloader even if you are on a custom rom but i suggest you to take a backup and install the stock firmware.
4) My opinion is that if you don't want to install custom kernels, cm10 or cm9.1, just leave the device as it is now mate.
5) Don't mess with things that you don't know because you may regret. Unlock bootloader only if you want to install the custom kernel or cm9.1 or cm10.
6) Here you will find a tutorial on how to unlock your bootloader: http://forum.xda-developers.com/showthread.php?t=1527159

I am using Xperia sola , rooted with stock ICS.
I want to eventually use a stable JB ROM.
I am not worried about losing warranty.
I want to know about the DRM keys.
Is there a way to backup or save "DRM keys"?
And then restore them when I want to relock bootloader?
