Hello everyone. I was wondering if there is some way to revert back to stock kernel after I install another one such as Doomlord's.
Since our Xperia phones will receive ICS at some point, I was wondering if I could have problems if I have an unofficial kernel on my phone (most probably yes), so I want to know if there is some way to revert back to stock kernel without much hassle if the need arises.
I think the kernel is flashed with the rom updates, since I can exclude it in Flashtool, but I want to be sure.
Thanks in advance and sorry for this stupid question.
Yes, there is. Instructions are stated in doomlord's thread (custom kernel for stock rom)
Basically, you flash the stock modules in cwm first. Followed by flashing the stock kernel (kernel.sin) via fastboot or flashtool.

[ how to get back to stock kernel OR older versions of my kernel (v13 and lower) ]
download the stock modules update.zip
extract the kernel.sin (or boot.img if u want to flash my older kernels) file from the stock FTF u used to flash this fimware
save the kernel.sin (or boot.img if u want to flash my older kernels) in the folder with fastboot binaries (fastboot.exe files)
save the modules update.zip to sdcard (on phone)
reboot phone and enter recovery
flash the stock modules update.zip
power down device
start device in fastboot mode
use the following command to flash the kernel.sin (or boot.img if u want to flash my older kernels)
Code:
fastboot flash boot kernel.sin
reboot phone and thats it u should now be on stock kernel (or my older kernel)

open your current rom zip, extract boot.img, reboot device into bootloader
'fastboot flash boot boot.img'
done
I was on official ICS till now, and I'm not very familiar with android's custrom roms, rooting, etc. I wanted to get JB via CM10 on my phone, so today I unlocked my bootloader on my Xperia S LT26i using this link (unable to post links so google it) Xperia S : Update to Android 4.1 Jelly Bean with Cyanogenmod 10 on androidlegend .com
It was mentioned that I should be having clockwork mod recovery on my phone and used this link to get it - How to Install ClockworkMod Recovery on Sony Xperia S on android.gs
I haven't rooted it, now it's stuck on clockworkmod and I don't know what I should do! Am i bricked? please help
ps: i used cmd to flash nozomi-recovery.img
Do you have cm10 downloaded on your fone already as a zip file? Or was it last still running ics?

It was still on official ICS, only with an unlocked bootloader, didn't do anything else! I'm a noob to all this so please bear with me
On a laptop/pc. Download advanced stock kernel and follow the guide here - http://forum.xda-developers.com/showthread.php?p=23181182#post23181182
Then you should be able to boot to ics again and be rooted with cwm. (keep pressing volume up when the lights come on on boot up)
Then if you already have cm10 downloaded on your fone just choose flash zip from sd. If not. Boot back up and download the rom before booting into recovery and then flash zip

Is it okay if I directly download JB rom and flash it via cmd fastboot instead of downloading stock ICS and flashing it?
As far as I'm aware you can only fastboot the kernel file. Hence y if you were on ics you need an ics kernel so you can boot up to download the cm10 rom to the sd card

So now I'll need to download stock ICS rom, flash it via fast boot and then download CM10 JB and then flash it via CWM? Thanks for taking your time to help me out..
You might find that just fastbooting the ics kernel will make it all work again as you've technically not changed the rom yet. Just the kernel file. If not just download a stock ftf firmware file. Flash with Flashtool and then start again using advanced stock kernel first.
Always keep a copy of the advanced stock kernel zip on your sd card. It's very useful even if you're on cm10 as some of the cm kernels wont flash properly

Hi guys any 1 can help me i want o install 1custom ROm but i flash and all and they dont boot i dont now why :S
and other questions where cna i fidn ftf files? for stock ROMS?
xd
BUMP
It doesn't boot because you need to flash a kernel compatible with that rom. The kernel file is the boot.img file inside the rom zip file, however, they do not always work. To flash a kernel you need to unlock the phone bootloader and use fastboot.

Yea thanks for link of Stock Firmware , and i know that i need unlocked bootloader for flash kernel but the rom i try to install its for locked phones and i try to install 3 diferent stock roms and then restore the custom rom but still not booting :S
i do wipe and clear dalvik cache i dont know why dont boot
If you flash a stock rom like NXT rom, you just need to flash the stock kernel. You can do this in flashtool, when you drag over the ftf file, check to exclude everything except the kernel for flashing. But then you're probably using stock rom in the first place. Make sure you don't flash a CDMA rom to a GSM phone and vice versa.
I had that problem once. The solution was to flash another boot image because the one that I was using was for ICS ROMS and my backup was GB. The boot and the kernel must be compatible with your ROM.
Hi,
I'm a newbie to this forum. How do I flash recovery using flash flashtool?
Thanks
You need to unlock the bootloader first,then flash a custom ftf in flashtool , flash kernel with fastboot(included in flashtool) - the kernel has the recovery built in. Then flash a custom rom or keep the stock one. A good place to start is this : http://forum.xda-developers.com/showthread.php?t=1836530. For the first time I would say to try Lupus GB v12 .
hi guys,
first of, forgive me If I cannot utilize google or xda's search engine for looking a good solution to my issue, I just cannot think of the right keywords to look for.
for several months now, I currently have CM11 fxp334 by pencam and Bootloader is unlock. Recently Im encountering random reboot issues and I think its getting worst and I am not sure if it has something to do with my link2sd, because at times when it does randomly reboots, I lose some apps that are link to my sdcard after booting.
1) Im thinking of either updating to the latest CM11(or CM12) nightly builds (I have cwm obviously) to assume that latest builds have less bugs
2) or is it possible to use cwm in trying to install/flash stock xperia M firmware because CM seems to be a power hog based on my own observation vs stock sony 4.3 JB. If this can be done, can some good soul point me to the right direction please.
I have my rest days, I hope I can use it by fixing my phone. Thank you.
Just flash your stock .ftf file to go back to stock.
You will have to reflash recovery tho.

flash by using cmw, or flashtool? can cmw recognize a *.ftf file?
and when you said that I will have to reflash recovery, I can still use the cmw recovery that Ive previously used with my CM11 together with stock sony rom?

flash .ftf using flashtool flashmode
afaik cwm only support .zip file for flashing
you can have cwm on stock rom when you flash stock kernel that includes cwm
flash it with flashtool fastboot mode
just press thanks if it's helps instead of typing it
