Debrand Sony Xperia P (O2) - Sony Xperia P, U, Sola, Go

Does anyone know how to debrand Sony Xperia P from O2 in UK (or just in general) ?
I have done some searching and there is some question about boot loader locks on some providers' firmware. Is this the case for O2 UK ? Does the boot loader need to be unlocked to put on generic firmware or change model id ?
Here is a procedure I found for debranding Sony Xperia S:
http://www.xperiablog.net/2012/03/26/debrand-your-xperia-s-tutorial/
This seems to be just changing the id of the phone, which then allows the Sony update service to put on latest generic ROM
Can the same one be used for Xperia P ?
This is FINE for me, I don't need custom firmware I just want generic stock firmware
Sorry for newbie questions but this is my first Sony Android phone (and a beautiful one it is too - no idea why this phone is not more popular)
thanks in adavance!

Unlock your bootloader and flash the generic ics image... I think it will be the best possibillity

Flash the generic firmware with Flashtool ..,
No need to Unlock your BL ..,some devices have unlockable Bootloader..,
But Flashing firmwares with Flashtool doesn't require an unlocked Or locked BL ..
It's easy as it sounds.. =)

[Q] Rooting and Unlocking the boot loader on NEO MT15i

Hi every one, my brother has an Xperia NEO MT15i, android version is 2.3.4, and the build number is 4.0.2.A.0.62
Anyway, he wants to root it and unlock the boot loader and he also wants to overclock (which will need a custom kernel)
My brother is a noob in android so he seeked for my help because I've rooted and S-off my HTC wildfire. But of course, HTC devices are different from Sony devices so actually I got lost while browsing the Neo forum.
I've found a way to root but its for build number 4.0.2.A.0.42
So if 62 is unrootable I'll need to downgrade to 42 first which also I don't know how to do it.
So I need a way to successfully root build 62 or downgrade to 42
Thanks in advance.

well my friend if you want to start testing custom rom's and making OC with your phone here is the official tool from sony to unlock your bootloader http://unlockbootloader.sonymobile.com/
then with the BL unlocked you can easily downgrade but for downgrade I recommend that you use this program "Flashtool" you can get it here http://forum.xda-developers.com/showthread.php?t=1351317
this program is very user friendly just hit the lightning and there are all the options but you have to know some hardware combinations like if you want to change the build you have to turn off the phone keep press back button and plug your phone to the pc with this you can put your phone en flashmode and for changing kernel's again phone off you press menu button and plug your phone your notification led should be blue and this is the fastboot mode, for the recovery mode when you flash an OC kernel with recovery just turn on your phone keep your eyes on the notification LED and when you see that turns on hit volume (-) in there you can install all custom rom's and stock rom's
i warn you that when you unlock your BL you can't upgrade your phone via OTA (over the air) because it will brick your phone

here you can find all the kernels, Roms and the firmwares
enjoy flashing
Read sticky threads in neo and neo v section, that way you will get fast inside view into Xperia Neo(V), ways of unlocking Xperia bootloader and flashing custom kernels. Also you can read sticky threads in Xperia Arc.
unlock boot loader,flash a custom kernel(recommend nightelf's latest for gingerbread) and install rootxperia zip via cwm recovery.google for root xperia zip.
Nightelf's kernel comes with cwm pre-installed

Hello XDA
I'm in the same situation than the user, but with one difference, under the service menu, my phone says "bootloader unlocking status: No"
Does that mean that I can't unlock it without paying or I still can do it for free under S1Tool?
My phone was bought simlocked to the Vodafone Spanish carrier.

Flashing Sony Ericssson Xperia Ray with Locked Bootloader

Hi,
I have been reading up alot recently about rooting and flashing my phone (Sony Ericsson Xperia Ray) as currently my carrier (O2) is not releasing ICS for updates as they have not "tested" it sufficiently on my particular device (this was there explanation to me via email).
I have looked on the official sony ericsson website trying to find a way to update my phone and found that the method there required my phone to have an unlocked bootlader but unfortunatly my phone has a locked bootloader (im assuming due to it being locked to O2 although it is a pay as you go model).
I have read conflicting opinions on whether you can root and flash your phone in my situation and was just wondering (before i tried anything at all) whether someone could clarify if it would be possible to update my phone to ICS.
For reference this is my phones status:
Rooting Status:
Bootloader unlock allowed: No
Thanks
Try find generic ics for ray, flash it using flashtool.
Or u can pay to make your bootloader unlockable.

Read http://forum.xda-developers.com/showthread.php?t=1695514
When you follow the Link Tutorial you have at the end Root and ICS on your Ray, without unlocking your bootloader (unlocking bootloader causes probably in lost your warranty!)
You need unlocking Bootloader for new Kernel and/or some Custom Rom´s, but there are some rom´s for locked bootloader.
Don´t forget to save your build.prop in /system befor you do something from the guide! With original build.prop you can flash your phone to O2 original software when there are something to repair in service center.

[Q] EU generic firmware?

Hello, I just bought a Z2 (D6503) that is never locked (SIM free), boot loader unlocked allowed YES but it has Vodafone firmware on it (Germany). Where do I get an EU generic firmware and how do I flash it?
Unfortunately Z2 is just released and there aren't any tutorials so that's why I'm asking you. Can I take the files from this thread: http://forum.xda-developers.com/showthread.php?t=2666849 and use this tool: http://www.flashtool.net/download.php to do it? Do I need to unlock the boot loader first? I would rather not do it if possible (yet).
Thank you.
