[Q] How to Backup stock Kernel + ROM ?

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.

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?

Yes you can use that, but you must flash this kernel after you flash that stock firmware to root.

The download link is fixed

Link to all official firmwares: http://forum.android.com.pl/f308/oprogramowanie-dla-sony-ericsson-xperiaa-arc-s-147007/
By the way, you can not root .587 you have to download .562 or like mentioned before just flash 562 kernel, root and then flash back to 587 kernel. But I think easier should be to download .562 firmware and then just root.

The easiest method is with an unlocked boot loader, install 587, flash CWM'd Kernel, flash Root.zip, done.

If your bootloader is unlocked you don't need X-Parts, if it isn't and you've wiped data then yes, you need to flash a stock ftf, which is what you should have tried already, then start over and when you get back into CWM, flash your backup.

[6.2.b.0.211]Need help after fail trying to root Xperia S

Hi, today I tried to update my Xperia S to 6.2.b.0.211 using this method: http://forum.xda-developers.com/showthread.php?t=2302631
But I got a brick which put my phone on a bootloop like the sony logo wouldn't disappear. So I used PC Companion to repair it and now I'm at 6.2.b.0.200 without root.
What I'm asking: Is there any way to root/flash a pre-rooted rom or whatever to have my phone rooted?
Thanks in advance.

Here is very easy and wonderful way !
1. Unlock the bootloader ! http://forum.xda-developers.com/showthread.php?t=1560613&nocache=1
2. Download flashtool and install it. http://androxyde.github.io/
3. Download doomkernel and SuperSU-1.25-Busybox-1.20.2-UPDATE.zip - 1.43 MB http://forum.xda-developers.com/showthread.php?t=2305591
4. Now flash the doomkernel via flashtool and restart the phone. Now when you see cool doomlord logo, pressing at 'volume +' you will get CWM recovery and pressing at camera button you will get TWRP recovery. choose any one of them and flash this 'SuperSU-1.25-Busybox-1.20.2-UPDATE.zip - 1.43 MB'
ALL THE BEST !

I'm not sure if it's region free but i can instal in on my Hong Kong version Xperia S so i believe it can be installed on yours
i believes most languages are here too
but there's only xperia international keyboard by default
seems other keyboard can still e added in setting
but the Xperia Chinese keyboard is missing and i have to flash it myself
if u dont like this version, u may look for another ftf file

i dont think unlocking the bootloader is required as it is a stock rom
btw, doing this will make u lose your bravia engine

u can root official . 200 FW. Your device must be UL, flash with fastboot doomkernel v5 and then you have CWM and root.

Your phone is Acro S (lt26w) or Arc S(LT18i)? Please check that because either You are trying to flash wrong ROM or are in wrong thread.
