Hello,
I cannot mount my SD cards in Android and also in ClockworkMod Recovery. So I decided to send it for warranty.
I currently have Xperia Pro (MK16i, Central Europe) with CyanogenMod 10.1, some non-stock kernel an of course unlocked bootloader.
I couldn't find any guide how to restore everything to out-of-the-box state and I would like to write some guide, but I need your help guys.
I guess that what I need to do is this: (in order)
Flash the stock kernel using Flashtool
Flash the stock ROM using Flashtool (as SD card is not working on my phone)
Lock the bootleader
I found this ({PRO} Complete List of Roms) great post with stock ROMs. I can find the stock firmware but I cannot find stock kernel. Could someone point it for me? Or is the kernel included in firmware?
Then I found this tutorial for Xperia Arc to Relock bootloader. It some file, I should flash it with FlashTool and it should lock the bootloader.
Am I right? Could you please revise my steps and confirm me or tell me what is wrong?
Thank you in advance

Hi , I want to ask some question about flashing custom roms like cyanogen mod on xperia phones
Currently i have Xperia ray with unrooted gingerbread 2.3.4 , 4.0.A.2.0.42 firmware
I want to flash cyanogenmod 7 and my questions are --->
[1.] How can i unlock boot loaders without messing up DRM ? bcoz i heard after unlocking boo loaders update service and some apps wont work.
[2.] How to re lock boot loader in order to get warranty back ?
[3.] Will i need to root my phone in order to install CM7 because , in cyanogenmod wiki they not mentioned root, but i think i need to root my phone
If yes then can i use "Xperia 2011 Easy Rooting Toolkit" to root my phone running on gingerbread 2.3.4
http://forum.xda-developers.com/showthread.php?t=1320350
[4.] how to install full functional clockworkmod recovery on xperia ray ?
[5.] While installing cyanogen mod after flashing boot.img , will i able to make backup of my stock rom ?
and how to restore it even i bricked my phone ?
or is it possible to flash ftf firmwares anytime using flashtools, or wotan . is there any official firmware tool for sony phones ?
and how to get official firmware in FTF file format
[6.] When i successfully installed cyanogenmod , will i get all option to install another custom ROM over cyanogenmod (i.e. CWM recovery and rom manager)
No developer replied my questions , after hours of research i found answers
[1]. http://androidflip.com/unlock-xperia-phones-bootloader-without-losing-drm-data-track-id-working/
[2]. re-locking bootloader is not possible this time for xperia ray , sony will solve bootloaders issue very soon , then we will not need to worry about this, although we will lose warranty
[3].no need to root your phone , it is like installing ubuntu on windows without knowing passwords
[4]. fxp made CWM for ray but this time it only works with cm7 and MIUI, there are some experimental kernels with cwm are available but i dont recommend them
[5]. of course you can make complete backup of stock rom
to restore follow this = http://forum.xda-developers.com/showthread.php?t=1382088
you can also revert to stock using flashtool , follow this = http://androidflip.com/how-to-install-android-2-3-4-gingerbread-update-on-xperia-ray-st18i/
[6]. definitely you can flash any custom / stock rom over cyanogenmod
maybe u can try my tutorial, but that's language indonesian, u use google translate dude, hehehehehe....
Hello,
I've recently got a new Xperia Ray with FW 4.0.2.A.0.62 (Gingerbread). I haven't flashed anything yet and would like to do so with one of the ICS roms. But I couldn't figure out (out of the many threads around) the steps to do so on this particular FW.
I have CM9 on my Nook tablet and am very pleased with it. I would be happy to have anything that works this well (and better) on my Ray.
Can someone please point me to the steps required (rooting, bootloader ,flashing, kernel etc), and also recommend a good ICS rom (speedy, light, kind on the battery) for the .62 FW?
Appreciate any info and apologies for the sense of newbiness.
thanks.
Check this Q&A Thread for your phone.
For ROMs, look in the Ray Development section, read the topics and compare yourself.
To install one, you have to do the following:
Download the ROM you want.
If it doesn't include kernel itself, download a kernel that is compatible with this ROM.
Place downloaded .zip file on your SDcard.
Unlock bootloader.
Install custom kernel via fastboot.
Install custom ROM via Recovery.
Unlocking bootloader and kernel installation is included in my tutorial, check my signature.
I just installed a custom rom and it just get a blank screen, I am running the sk17a and was wondering if anyone has a link for a ftf file so I can flash the original rom. Media fire links are not working..I installed the minicmsandwich_lite_final and it doesn't boot. Is this rom only for sk17i? THanks
No, you can flash the rom regardless of having sk17a/sk17i but just make sure you have the proper kernel instaled, are you trying to flash it on a locked or unlocked bootloader?
Yet again...first sticky on forum, step nr. 6
Hi again,
I kind of feel bad for almost only asking questions, but this place has been and continues to be a fantastic resource for learning when my search results turn up dry.
I'm running my Z2 on the generic, international .402 firmware with a locked bootloader, rooted via the easy root tool. I have Nut's PhilZ/TWRP dual-recovery installed, but the rest of the phone is stock.
As explained in this thread, the dual-recovery from Nut works on both locked and unlocked bootloaders, so long as you're using the stock Sony kernel (which is the case here). I'm planning on unlocking my bootloader and flashing either Carbon or CM11 soon, but I don't know what will happen to the recovery: will the dual-recovery no longer work because a new ROM (and new kernel) have been flashed? Will this version of TWRP work in its place?
If anybody has flashed an AOSP ROM onto a Z2 and could provide some insight, it would be a big help. Thanks.
Hi.
All you have to do is flashing NUTs dual recovery right after flashing your custom rom. Then you should keep your dual recovery.
More information could be found in the following thread.

Is there a way to root my Xperia Z2 (4.4.4) without unlock its bootloader?
Or else better, is there a way to back-up the bootloader before the unlock?
I ask because I want to root it without set a custom Rom.
Thanks in advance.
There is. You've got to downgrade to for example 4.4.2, root your phone, create a pre-rooted version of 4.4.4 and then flash that. There is a much more detailed guide around here, so I recommend that you check that out
To back up your ta partition you will need root first.
In stead of creating a rooted rom you can also find some prerooted here in the development forum.
-Use flashtool to downgrade to 4.4.2
-Root and install recovery with one of the available root methods (towelroot for example)
-Use recovery to flash a rooted 4.4.4 zip, recovery (again) and SU (again)
-Reboot
-Test network connection, if 4g is not working, use flashtool to flash a local 4.4.4 baseband
That's all.
I heard that for rooting it's required to have unlocked bootloader. Is that true?
(I have seen the root guide in forum, but I don't think that it mentions the bootloader)
My problem is that I want to upgrade the phone without errors (when sony has updates). I say that because a friend of mine has a rooted Nexus 5 with unlocked bootloader and he can't install the last update.It gives him a bootloop and returns to the previous. This is something I don't want.
Thanks in advance.
Unlucking is not needed.
Official updates should work if you're on a 100% stock rom, but updates are generally available as flashable rooted zip, here in the forums, long before you get an official update available from Sony.
So that should be no problem.
Biggest issue here that people dont search howto root on locked bl, that is possible, search and read then you will have it, example like the installations steps of a modded stock rom
