I am on Xperia Arc with unlocked bootloader, with CM 9.0 & CWM Recovery 5.
Before flashing to CM 9.0, I made full backup of my stock ROM through CWM Recovery.
Now I want to go back to my original firmware (i.e. 4.0.2.A.0.42).
When I try to restore backup from within CWM recovery, my phones is stuck at boot after free-xperia logo. Only black screen with nothing on it.
Someone please help me, how can I restore my backup of stock ROM.
i want my phone as it originally came....
plz help....
thanks in advance..

You must flash the compatible kernel for that firmware
Doomlord's kernel for stock rom for example.
As you mentioned, you already restored the GB stock rom; you only need the proper kernel now for it to boot properly.
FXP kernel works for CM only.

You must first flash .42 firmware and then install CWM or doomkernel(it comes with pre-installed CWM) and then perform the restore
tryed SEUS?

There is no need to relock the bootloader.Just flash the firmware and you'll get back to original kernel and the doomkernel well be gone

You may try to relock your bootloader, use SEUS to flash the phone. There's an option in SEUS that you can select and it will not wipe your data.
OR
Extract the kernel.sin from an ftf and flash it via fastboot, then you can return to your original kernel
Hello Guys !
I wanna try some custom ROM so before doing that want to backup my Kernel & ROM. If anything gone wrong so I can revert back to original ROM.
My Cell details:
Xperia Arc S
LT18i
Android Version 2.3.4
Baseband Version -64
Build number
4.0.2.a.0.62
Locked bootloader
& unrooted.
Please someone guide me....
Thanks in advance...
If your bootloader's locked then you can't back up. You can only reload(repair)it from PC companion.
sinkster©
Thanks sinkster !
Ok done unlocked bootloader.
Then advice the further steps...
XPERIA CWM AUTO INSTALLER
download this app and install CWM recovery on ur phone...
Then reboot ur phone into recovery mode...
TO DO THIS, LONG PRESS BACK BUTTON WHILE THE PHONE RE-BOOTS
(OR)
KEEP TAPPING VOLUME DOWN BUTTON...
After it boots into recovery, go to BACKUP & RESTORE and Select Backup...
This will create a NANDROID BACKUP on your phone exactly as it is...including apps n contacts n all other data..
you can find it in SDCARD/Clockworkmod/Backup/
Good day...
If you wanted to take a backup without installing CWM you can use fastboot to boot (not flash) a kernel that has CWM built in.
thanks amulbaby
I will try and get back here with comment ...
EDIT:
I tried that steps but it will works only on rooted phone ..., can not enter in to recovery mode by pressing any key, it normally boots up and appear home ...

Why don't you root it with flashtool then?
But for that u wud have to downgrade to .42, with flashtool before rooting
Hey I am also wondering about this. I have lt15i flashed with Official .562, locked bootloader and CWM installed via flashtool.
Which ICS roms will work with official .562 and locked bootloader? I have been searching all morning but not a lot of updates regarding this since the official .562 release.

Here is the point I was looking for these alternative . . .
I have STOCK ROM with 4.0.2.a.0.62, actually I want to backup these stuff, I read about that downgrading via flashtool and root, if I flashed via flashtool that STOCK ROM will wipe...
Anyway here what I did to make a copy of my stock firmware & upgraded to ICS firmware & rooted.
Repaired my phone using Sony update service to download and backup STOCK firmware
Flashed with flashtool official firmware LT18i 4.1.A.0.562 NCB Icecream Sandwich Official
First you need to download a kernel that has cwm built in, I would search for recoveryARC.IMG then you also need fastboot from the SDK.
All you would do is connect your phone I'm fastboot then run in a command prompt fastboot boot recoveryARC.IMG. Your phone would then boot using that kernel and you can enter cwm by pressing the vol down several times. This process wouldn't flash your kernel only load it temporarily.
I would try and find a guide about them but I'm on my phone.
Sorry just noticed you've already done it, congrats enjoy ics.

Thanks bro ...
I already upgraded, anyway I want to know the process, you mentioned here this process wouldn't flash kernel only load it temporarily, I am confused...
Could you describe in details .. ? Actual what happens if we flash recovery img...
Well you can use fastboot to install the kernel which overwrites the previous one, or you can use it boot the kernel which just sends the kernel to the phone which the boots and temporarily uses the kernel. However when the phone next shuts down it will return to normal use.
If you flash a kernel it writes the .IMG to the boot partition. So if I wanted to use a kernel that stayed between reboots I would use 'fastboot flash boot kernelname.IMG'
However if I was running stock I could use recoveryARC.IMG with cwm, and do fastboot boot recoveryARC.IMG then run update.zip as normal. Then all you have to do is reboot, you'll be back to stock but the update would still be installed.
Sorry if it's not cleat, the best I could do on my phone.

Can you please give me details on you did this? It is precisely what I want to do (ie. Backup the stock carrier rom on my Xperia Arc before flashinging an old ROM in order to root it).
Did you use the "repair" option from "Sony PC Companion 2.1>Support Zone>Phone software update>repair phone"?
Or did you use the software from here: http: // w ww(dot)sonymobile(dot)com/gb/tools/update-service/
Can you please tell me the whole procedure on how you did the backup of the STOCK ROM? Thanks!

ROM backup OK; How to take backup of Kernel
I am using Sony Xperia Ray ST18i
used it for a year with stock kernel and ROM
rooted it long ago, but was afraid of custom ROMs
last month I unlocked bootloader, flashed ROM and custom ROM (beanstalk 4.3.075), enjoying it but obviously not so stable like stock
Now if I wish to move back to my stock kernel and ROM
what steps are required.
I suppose
1. flash the stock kernel
2. restore from backed up ROM (I do have nandroid backup of stock ROM)
but how to achieve the step 1, as I learnt nandroid backup doesn't backs up ROM.
My collegue is having same phone still on stock, Can I use his phone somehow to extract kernel. I searched and found a zip to be used through CWM which backs up kernel it was meant for some samsung phone I tried but failed.
Thanks in advance.
Do I need to supply some more information to get help?

you need to flash the kernel. kernel CANNOT be backed up by CMW on our devices
Pvy.
i tough that it was backed up too. where could i find the stock kernel now as i didnt backed it up? and as i dont have unlocked bootloader is this a problem? i just rooted the phone and installed the cwm for xperia from the play store, the easy way. i would like to not unlock the bootloader.
how could i restore the old kernel now?

download the gb stock ftf for your device and then flash it via flashtool.. use the latest version as it supports locked bootloadrs also.. then unckeck everything in the pre flashing dialog box except kernel.. Maybe this worls for you..
But keep SEUS ready if something goes wrong
Hit thanks if I helped..
i would recomend the ASK kernel by doom
has rooting and CWM all sorted for you with the stock kernel if you are looking for a stock kernel.

Hey fellow xda members,
problem is that i was using stock rooted .53 ics rom with unlocked bootloder and ics stock plus v17 kernel, wanted to test official CM 9.1.0, so i backedup my rom and installed CM and wrote boot.img (thru adb) which came with CM rom, now i want to restore my backup but No matter what recovery i use, it says md5 dont match, i checked md5 sums and it matchs with the md5 file in backup folder, the thing i assumed is that i have to flash stock kernel and for that i have to download full firmware to get stock rom back, but my internet connection is too slow and stops downloading firmware at 190~200 mbs, is there any solution without downloading firmware and extractin stock kernel out of it? if there isnt any other option thn plz give me a link to stock kernel.elf.
thanx in advance!
Edit: Thanx everyone problem is solved, i renamed my backup earlier (as i do in my HTC One X+ but these recoveries doesnt support spaces in bacup names) and nandroid.md5 file was damaged, these two reasons were stoping me to restore my backup
Please move this thread! Moderator!

You can flash Advanced Stock Kernel, SSpeed Kernel, even the recovery kernel made by bin4ry, format everything and then try to restore your backup again.
Hi All,
I was wondering if you could help me out and advise which kernal and ROM would be best to use for my R800i
Android Version: 2.3.4
Build Number: 4.0.2.A.0.42
Many thanks Thanks in advance
If you bought your Play only, only for pure gaming, there's nothing better than JokaWildv3 with Doomkernel v14. Forget the other kernels and ROMs, feel the real power of that monster in your pocket with these two!

I am noob to all this and wondered if the DoomKernal is a pre-rooted kernal or do i need to root first via flashtool?
Also can i keep the firmware at 4.0.2.A.0.42 or am i required to change this too?
Thanks
Yes, it's pre-rooted so no further rooting is necessary. Here's the link for the both:
JokaWild v3:
http://forum.xda-developers.com/showthread.php?t=1532883
Doomkernel v14:
http://forum.xda-developers.com/showthread.php?t=1176502
And yes, I strongly recommend to change your FW to .62 or .69. I've tried with the new .79 one btw, and it worked like a charm. Newer is better I guess?
I'm here for a while, so feel free to post if you encounter any problems.
Good luck!
Thanks for your help!! :fingers-crossed:
I'm at work so wont be doing it till I get home but will post if I come across any issues but I have a couple of questions
which order do I do it in? Do I flash the firmware to .79 then the kernal and then the ROM or in a different sequence?
Also does the DoomKernal v14 contain CWM Recovery or do i need to install this after flashing the kernal?
Do I also need to install the goggle apps and the wifi module?

Yes I'm a total noob
You're welcome. And my bad, I was going to explain them but I forgot, I'm kinda sleepy, sorry .
1.First flash the FW via flashtool.
2-Copy the JokaWildv3.zip to your memory card. Any location is fine.
2.Boot your device in fastboot mode and flash Doomkernel v14. It contains CWM Recovery module, yes Doomlord handled everything.
3.Reboot your device, when the device vibrates AFTER the Doomkernel logo, press the back button. Select the CWM recovery from the menu, then select install zip from the card. Choose JokaWildv3.zip (Do NOT extract the files). The installation process takes 2 minutes. After that, reboot again and enjoy!
Thanks for all you help, I'm sure ill be in touch if i fail miserably.
Just to confirm, I don't need to root first do I? the kernal is pre-rooted?
So once I've unlocked my bootloader I can just flash the kernal, wifi modules and then install the ROM via CWM?

Right, it's already rooted. And it contains Google apps and a file manager, all you need to do is installing and enjoying.
Thanks El Diablo for all your help, all done and dusted was a lot easier than anticipated.
You are most welcome, my friend. I also recommend you to try the Krisdee's upcoming ICS ROM (not available yet), it looks promising.
