[Q] Can I Go back to Stock 2.1 with unlocked bootloader?

Hi guys, I have a X8 with GingerDX 21 and doixanh linuxkernel 004.
I'm going to sell my Xperia and the new owner wants to go back to my backup of stock eclair 2.1...
Can I restore with CMW? I made it with xrecovery... If not, how can I start the xrecovery instead cmw?
Can I restore the backup with no problems with my bootloader unlocked?

You can recover the stock kernel and stock ROM to the device. There should be links to those around here somewhere.
Also, you can try to install xRecovery again, but i'm not sure if this is possible when CWM is installed already..

I have my backup of stock rom.. if I restore from recovery, must I flash first a stock kernel too?? Is not the kernel in the backup?

I think that theres an option to restore xRecovery backup in CWM.

NAND backup (made with recovery) only backups ROM, so, yes, you will have to flash stock kernel as well.

-Install stock rom with cwm or xrecovery (phone will bootloop) then
-Flash stock kernel..
There u go...

You should use the Flashtool link, which flashes the stock ROM & stock kernel at once

Now crossing my fingers and flashing...
Original Kernel flashed. Any problem! Now everything is a breeze thanks again.

[SOLVED] [Q] Getting back to stock ROM

Hi all
I have rooted and unlocked the bootloader but haven't taken the jump and stuck a ROM or kernel on as yet, as am actually quite happy with the stock ROM, and also rely on the headphones, amongst other things - which appear to be a problem on some of the ROMs.
If I do stick a custom ROM on, can I easily get back to the stock one, is there a stock ROM of that which I can flash via CWM ?
I understand that with CWM I (currently) have to instantly stick a ROM on, so presumably cant do a backup of the stock ROM at that point..before putting on FXP or some such
I presume I can use the sony update service, but would that wipe the root ...?
could someone enlighten me
many thanks
nat

Take a backup of what you have now in recovery, and you can always restore.
Also there are plenty of stock .ftfs in the allin one thread in Q&A that can be flashed in flashtool
No.
if you flash cmw from the thread then yeas, but you have unlocke your bootloader, so just flash the advanced stock kernel and then you have recovery without having to reflash a rom...

that has CWM rolled up in it?
and I can simply type
fastboot flash boot Tkernel.elf
using the version of fastboot that came with flashtool
with the phone in fastboot mode (blue LED)?

[Q] Help How to flash stock rom

Guys please help
I flashed a custom rom and it got a lil messed up..
I've downloaded an ftf file but I have no idea on how to flash it.
I havent made any backup,my bad.
I'm using C5302

If you look a bit futher you will see a easy guide made by me about how to get back to stock without the use of flash tool

You have to download flashtool to flash an ftf file if you don't have any backup you lose your data but once you flash the ftf you're going to be fine

If you haven't unlocked your bootloader you can also use Sony's update service (SUS) to restore your phone.

Flash toool

Thankz,By the way.. i have suggested that i could also flash pre rooted stock and den 201 kernel.. any ideas on that?

@ OP You have Q&A so quit PM me and ask all your questions here

The quick answer is yes - use your recovery to back up your rooted stock ROM. If you don't like CM simply return to your back up - it will still be rooted.
Alternatively, you have an unlocked bootloader - so you can flash Doomlord's kernel immediately after returning to stock (the kernel is insecure meaning you can flash a supersu zip in recovery to get root again).
Doomlord's latest kernels are decent and I can recommend Williams kernel too - as good as stock.

[Q] Questions before enter the UBL world

Hello people.
I've passed this whole week seeing posts about unlock bootloader, and i want to put some Lollipop ROMs in my smartphone. :fingers-crossed:
But i've some questions that i don't have found the answers.
- The first is: Do i need to be in the stock firmware to unlock the bootloader? Actually i'm with LBL, and Slimkat ROM, but i have the stock FTF in my archives.
- The 2nd: I have made an backup of TA Partition, but if i want to relock my bootloader again, what steps i need to do? Relock -> Flash Stock FTF -> Restore the TA partition backup or simple Restore the TA partition then flash stock FTF?
- The 3rd: The Tangerine Kernel, Willians Kernel and DooMLorD Kernel are really safe to use? I've heard rumours about modded Kernels can overclock too much your processor and make it explode.
Well, i think is only these three really. And thanks advance to all you guys that answer my questions.

1st
Afaik you don't have to, but i would recommend it.
2nd
You have to be on stock to relock bootloader. Custom Rom won't boot anymore when your BL is locked again.
3rd
You can deactive overclock on costum kernel. Then nothing can happen

Thanks.
About the 2nd question. Whats the procedure i would make to come back to full stock if i'm in an UBL ROM?
Flash Stock FTF, then Relock, then restore TA partition?

yes that is right

Thanks man.
And about the kernel flashing process...
First time i think i'll make it with flashtool... but everytime an new update roll out, i i'll need to flash it with flashtool too, or can i use an custom recovery like CWM?

to flash what kernel ?
you can flash a custom kernel via cwm for sure
but every ROM you flash will have a stock kernel
when you UBL you can install twrp recovery via installing rashr app then from the app install twrp.img
if that answer didn't help ....make your question more clear

Tangerine Kernel for example... the dev that make it keep updating it, and if i want to flash the new version of the kernel, do i need to flash it via flashtool or cwm/twrp/philz?
And about ROMs that have the kernel.elf inside the zip package?

no ...just flash it through the cwm/twrp/philz
and if you want to flash kernel.elf again just flash it using fastboot mode
but if you want to stay on stock kernel just flash the ROM ...nothing else
