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?

Hi, Janto
For me, just flashing a custom rom it can't block u getting into cwm. It may stuck with the Kernel's logo/bootAnimation but should passes the CWM notification first.
If you could provide info(Name & version) of your kernel & rom, it would be better for us to help you bring your expensive device back to life:fingers-crossed:
My suggestion is:
1. Use Fastboot to flash a good kernel (Anyone from the development section), then CWM, thought you know how to do a flash again
2. If above step not works, download flashtool (The top thread in the development section) and a complete tft files, then do a flash using the flashtool, this should give you a brand new phone.
BTW: you r BL or not? search for X-parts if u r still locked.
Hi every one I have rogers arc running on the latest ice rooted Bootloader was locked. I did bootloader unlock with test point.The flash tool saying that bootloader is rooted but I cannot flash any custom rom or even a backup I usually can't pass Sony screen any input is appreciated.

Just use flashtool to flash the rom again man, i think u should flash the stock rom firs
If it's ok, then flash your custom rom
I am running the official rom no problem it's not allowing me to flash any custom roms in the recovery mod. I cam reboot to recovery either by x-part or holding the menu key while it start.:crying:

You unlock your boot loader with the test point, not root. So please be clear about what you've actually done.

If you want to use a custom ROM then 9 times out of 10 you'll need to use a specific kernel, usually one that comes with CWM.
I know exactly how to flash custom rom, I am coming from MT4G the problem after you flash the rom the phone dosn't boot in recovery it just stay at sony logo, even when i try to boot in fastboot mod dosn't allow me only booting in recovery.

Try this....
1. Flash ur stock ICS firmware 4.1.B.431 ... 2. Don't let it upgrade to the latest firmware (in Canada I got N update that changed my firmware to 4.1.**.587 or something like that)
3. Then flash ur phone with the rootable firmware of xperia generic world version...
4. Flash the kernels for that firmware .. even the stock ICS would be OK..
5. Root the phone using Doomlords method of rooting... Its the best...!
6. At last reboot ur phone ..n violaaa...
U have a completely rooted phone ..!
P.s. make sure u see the log while u root ur phone . It may say rooted successly even if it had some errors... so make sure other are no errors..!
I had the same problem when I decided to unlock boot loader n root it for the first time ... so no worries my friend ...try this .. n it will work for sure.. !

I think you can't flash custom rom from flash tool it must be flashed from you sd card because it is a zip file. I tried to flash recovery mode you supplied the link with no go.
So u did root and installed cwm by the link I gave right ?
N it showed that .. installation complete.. ?
N now ..the problem is ..
that u cannot enter recovery mode
To flash a custom ROM ?

If your bootloader is locked, you can repair it with Sony's PC Companion program for windows.
If your bootloader is unlocked, your only choice is to use flashtool to flash stock firmware

hey thanks for the reply, i read around a bit and downloaded flashtool, but when i run the flashtool it says 'preparing files for flashing' and then my phone just goes and reboots to get stuck on sony ericsson again, not giving time for flashtool to flash the phone.

You have to switch it off first before connecting, then connect while holding back when they ask you to in Flashtool.
Just to be safe, remove the battery and replace it after switching off.

Download the zip on the sdcad then install this kernel.

Well first you need a unlocked bootloader.
Then, you have to flash a ICS kernel for an ICS ROM (using fast boot)
LuPuS is a good kernel and is pretty stable too.
After that just install the ROM through CWM.

I don't know about that. But you can try it. In worst case, it won't do anything at all.
But i'm sure that Emma (son'ys flashtool for unlocked BL) will work. Here is a link
