I think what you want to do is:
Downgrade to .532 (see my downgrade sticky thread)
Root using Bin4ry's or [NUT]'s tool - If you dont want to unlock the bootloader then use [NUT]'s tool as it will install recoveries as well
[install recovery]
As it looks like you want to keep a locked BL then look for [NUT]'s .290 rom thread and install
Then look for [NUT]'s .136 rom thread and instal

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
Should work on xperia go also.
Didn't make a separate thread as I got the same doubts.
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?

I don't think there's a kernel repository yet, but it's pretty important so when I get some time I'll set one up unless someone beats me to it.
Check in original android development section, @krabappel2548 has done a 523 dual recovery kernel, not sure about 290 though.

Will this work on stock 4.4 with Locked BL and no recovery? Will this disable X-Reality?

this is for 4.4.2 (in correct image on youtube)
It will require an unlocked bootloader. But with 4.4.2 unlocking bootloader doesn't break the x-reality.

This doesn"t work for me. Flashtool refuses to recognize that my Ultra is in fastboot mode. I downloaded the drivers, uninstalled and re-installed Flashtool but I get the same result. I can't install the kernel. My LED is blue on my Z Ultra but Flashtool gives a message saying that I must be in Fastbboot mode which, I am in Fastboot mode as far as I can tell. Not sure what to do now. BL is unlocked and I am on the the KitKat 4.4.2 .681 firmware. C6802.
Try to reinstall all drivers by connecting your phone and install Sony pc compagnon... Maybe it'll work !
Just give it a try !

Thanks. I was able to get into fastboot mode and install the kernel, finally! Now I have root on my Ultra with the new KitKat .681 firmware. Still not sure what the problem was. I suspect it was my desktop PC. It runs Windows XP. I switched to my laptop that runs Windows Vista and just re-installed PC companion and reinstalled Flashtool and the drivers from scratch and everything worked like a charm. Happy to be rooted on KitKat 4.4.2!
Device: Sony Xperia Z Ultra C6802 Android 4.4.2 firmware .681.
That's awesome ! It was a pleasure !

I have a Bell Z Ultra
When I check online apparently Z Ultra is on 4.4 and when I use the PC Companion app it says my device is up to date. Anyone know what's up?
You have to relock bootloader first if unlocked

You have a Bell Z Ultra
Using the *#*#7378423#*#* to get into the Service Info it displays ""Bootloader unlocked allowed: No" so I'm assuming it is indeed locked.

Dont you need a unlocked bootloader to do so?
If not, which would be the best one for my model, it's LTE.

Not to flash a FTF (pure stock sony firmware) just find a c6806 .757 FTF and download the latest flashtool, see the stickied guides

Yes works perfectly.:good:
I too updated through ota recently ..

You don't need ftf.
Just download those three files.
What I did for my D6502 was :
I put the .291 into card and start!
>>Flashed the .575.ftf through flashtool
>>used that recovery tool provided
>>again flashed the .291 through recovery
Nothing changed all I get was root and I'm happy!!:laugh:
Thanks for all i rooted my phone

I'm a newbie and haven't rooted any phones yet. could you please tell when to install TWRP in simple words?
You need not unlock your bootloader.
1. You need to root your phone with appropriate tools taking consideration to your firmware version.
2.Then you can install twrp. It's easy as just double clicking the installation files.
PS: I hope you are already rooted!
