As my XU has been rooted and unlocked, I would like to give CM9 a try
But I guess I have to flash a new kernel during the process and I think it is better for me to backup my kernel.
I know that CWM could backup my stock ROM but is it including my kernel?
I just don't want to restore my phone using US method and root my phone again
No need to backup ur kernel
U can get it from a ftf file

Change kernel back first (flash stock kernel) and then restore backup.

Thnx for the support
hello people, this is probably the noobest question in the world ever but is it possible to switch from rage kernel to x-kernel without factory reset or anything.
its been a while i didnt play around with custom roms and kernels and make me forgot how to do so.
im currently using a rage kernel with stock .62 gingerbread. i found out my battery drains too fast. not sure if kernel problems or batterry problems.
now i want to test out other kernel which is this http://forum.xda-developers.com/showthread.php?t=1451150 X-kernel. hoping for it to give a better battery life than rage kernel gb.
so how to do this process again?
im too busy to check out the tutorial somewhere here. **** me, right?

Do a nandroid backup using clockworkmod before flashing xkernel . Flash the xkernel . If you lose data then restore the nandroid backup which you created before while you were using rage kernel.
I don't think you'll lose your data but it's always a good thing to do a nandroid backup. You don't know when you'll need it .
PRESS THANKS IF I HELPED YOU!!

No, x kernel should be prerooted, too. Just flash it, it should work. But doing a nandroid backup first is a good idea, just to be on the safe side

im afraid i will lose root during the flashing process. cause im using link2sd. if root gone, the link2sd will go crazy and all my linked apps will be gone.
but thanks will try it tomorrow
No you won't lose root. Xkernel is a prerooted kernel.

So I had this rom (http://forum.xda-developers.com/showthread.php?t=1876792) and i wanted to go back to my official rom. I went to CDW wiped out system, date, ect etc and I tried to restore my backup which I did with my CWM before I use the custom rom. Everything ok but when I reboot me device it shows the bootlogo of the custom firmware and not the sony and after that it goes black. How do I solve this? I searched but I didnt find anything
Please be more exact on what you wiped and formatted all. What kernel and cwm version are you using? Did you made the nand backup with the same cwm version?

And you flashed back stock (based) kernel?
When you flash .ftf rom using a flashtool, it flashes all official components (rom, kernel, baseband) by default. I apologize flashtool is a most useful method to go back at stock rom. What do you think?

Download flashtool. Download ftf of firmware u want to flash. Open flashtool and drop that downloaded ftf file in flashtool window. Then check no final verification. Click ok. Then follow instructions given by flashtool. Done. Simple as that.

And be careful with device drivers. Install it from a Flashtool folder to avoid a flashing problems.

One last thing, as I said in my first post before i go to jelly bean i made a back up using CWM(The backup was on official ICS 4.0.4 + rooted + BL open). If I want to go back at that backup the only thing i need to do is go to CWM, delete system, delete data, detete etc etc and I do the restore?
Or I need first to flash a kernel for ICS and THEN restore the backup? Im still kinda confused with the kernel thing and the restoration...

Yea. Cwm doesn't reatore kernel. Just the system, data dalvik etc.
You'll need an ics kernel like alliance or suave to boot into the restored backup.

So that was the problem. I can use any ICS kernel or the official kernel( because the backup was on the official rom even though it was rooted) ???

Any kernel compatible with Stock ics

I recommend you to flash a kernel that has been used at time you created a backup, because I had a problems with Wi-Fi when I do «hot-flashing« from suave kernel to night - elf.

If you have the firmware ftf of whatever firmware cwm backup u had taken use it and only select kernel.sin and don't select wipe anything

If I format system will it delete the backup?
Also If I install stock kernel back from custom kernel then do I have to install CWM again?

The backup stays on the memory stick so copy it in your pc in case something happen
No you will still have cwm

If you used cwm from kernel, then yes, after you flash stock kernel, you will need to instal cwm to system.

From where?
I highly doubt that someone with custom kernel would go and install cwm in system.
Guys,
will it be possible to come back to the stock ROM by anychance if I update my phone with a custom by rooting it?? that's my major question. please advise?
Yes, it can be done download the original firmware of your phone and flash it as flashing some custom rom.....
Don't forget to hit thanks
Sent from my WT19i using xda app-developers app
yes just find the original firmware .ftf file and flash via flashtool.
Flash Stock Rom .ftf file or restore from Nandroid Backup if u have created one..
But After flashing to stock.. Root will go..
If u restore from Nandroid backup.. U will retain your root

Download the .ftf file for your particular device from above thread... And then just flash the downloaded file by flashtool...
You will loose your root (bootloader will remain unlocked if you unlocked it previously)
press thanks if I helped you

In philz change the back up method to .tar and instead of .dup
go to -recovery-backup and restore-choose back up method - tar.
there have been some reported problems with .dup method.
then try making making a back up again, it should work.
Dude ur absolutely rite man.finally it works thank u soooo... Much for ur help
