[Q] Installed cm9...not able to restore gingerbread..plz help

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

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

CWM is for flashing ROMs. You don't install it, once you've unlocked your bootloader and downloaded your sdk's etc, set up fastboot on your PC to boot custom kernels which contain cwm.
Your phone won't be blank, just user data(not sdcard)will be wiped. Follow the instructions on the SE site, or here.

How to install latest Recovery?
Hi guys. I have just one simply question. I just unlock my bootloader at my ARC S with installed latest Android 4.0.3 4.1.A.0.562. My question is:
How can I install CWM Recovery on it?? I'm asking because all of these tips were written for Android in version 2.3 and I don't want to brick my phone during using wrong guide.
If it's not a problem redirect me to proper Guide and tools.
Thanks

Like I mentioned, CWM isn't installed, as such. No matter what version of android you're running, if you've unlocked the bootloader then, using fastboot, you can boot a kernel that contains CWM.

need guidance..pls help

Unlocked bootloader, right?
Well... I started flashing with the FXP CM based roms. I suppose that this is exactly what you did, but since you didn't tell the steps you followed, I'm gonna write down how I did the first time:
With an FXP CM based rom (eg: FXP CM 10) , the steps, basically are:
- Extract the boot.img (own kernel of the FXP roms) of the .zip and put the .zip in the sdcard
- Flash the kernel in fastboot mode:
( fastboot -i 0xfce flash boot boot.img
fastboot -i 0xfce flash reboot
unplug the usb and start hiting volume controls to enter in CWM)
- Wipe data and cache
- Install the .zip (rom)
- Reboot and enjoy
Hope it works for you.

Aactually I am not. Able to flash kernel image with fastboot.. I mean with flashtool I am not Able to flash kernel image.. flashtool is showing error that my phone is not rooted.. but it actually is..
And suppose if i want to install ROM( jelly sandwich) can u tell me the procedure from the scratch, I ll really appreciate it.. coz I am trying for 2 days with negative result...

I'm noob too, so unfortunately I can't help in the most effective way.
The only apparent difference between our phones (from what I understood from your post) is that I unlocked the bootloader. I read here in XDA that some roms just need this while others not.
"can u tell me the procedure from the scratch, I ll really appreciate it" - You mean unlock the BL?
It's easy, but may void the warranty... Go here: http://unlockbootloader.sonymobile.com/instructions
(Note: In my case I didn't install the sdk, but I just can't find the tutorial that I followed to unlock the BL... Anyway, the tutorial that I've used was in portuguese... Not much help for you I guess
Note2: In the middle of the process, you'll have to inform your IMEI in the sony website... Use just the first 14 digits).

There is enough information in the guides and stickys to help with most things, People just need to read it.

When I want to know sth, I search and then I will have more than I wanted.:angel:

1. unlock the boot loader
2. Download a custom kernel for your current version of android ie: GB/ICS i suggest DoomLord.
3.Put the kernel ( .img ) into the same folder as you have fastboot/adb
4. Power the phone into fastboot: Power down your phone. Press and hold the menu button then plug in your usb cable (the light on the side will be blue)
open a CMD window in the same folder as fastboot/adb and type the commant:
fastboot flash boot NAME OF FILE.img
push enter.
Once the install is complete (a couple of second) you will have root and custom recovery.
Make sure your phone version is rootable
There are guides available in the General section, I suggest you read them if this is your first root.
Good Luck.

Thanks guys I appreciate your help.. I ll try

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 ?
Am I right ?

[Q] Xperia SL from stock to beast :)

Hi,
I'm new and quite a newbie with android so, please bare with me
I will try to write a comprehensive guide on this during the process.
My device is XperiaSL LT26ii / Android 4.1.2 / Kernel 6.2.B.1.96 (stock, or default kernel) Rooted with bootloader locked. Busybox installed.
So the only thing I'v done after buying is rooting it.
- How to fully-backup / recovery if anything goes wrong
Before doing any operation with it I wanted to backup everything (applications, ROM, System, documents) , and I hear that there is CWM or Xrecovery for that (mentioned in some guides), nandroid, but I found different applications on Playstore and don't know which one is the right one for my device.
I understand that backing up and restoring each of these system parts requries order and probably different applications,
Can we specify here which app should I use and how it's done?
- ROM and Kernel without unlocking possibly
http://forum.xda-developers.com/showthread.php?t=2593806 it looks like possible but considering that now there is cm-11 out and not yet for "nozomi" http://download.cyanogenmod.org/?device=nozomi , I would like to try any stable, fast , light ROM out there which works for my device. Preferibly with possibility to remove any google app .
If not, how can I unlock the bootloader and do the rest?
I saw also http://forum.xda-developers.com/showthread.php?t=1617219 which looks a nice kernel.
So , what's the most adaptive ROM / kernel for my phone and how to install / flash them?
- Getting back the applications
Once it's done, how to restore back applications and data? / with what tool, without loosing anything.

Download flashtool (xda fileserver)
You can use that to unlock your bootloader
Also backbuton = volume up = BOOTLOADET MODE
Menu button = volume down =flashmode
May come in useful for unlocking your Bootloader
Also emma flashtool isnt the same as this flashtool
Also google if your not sure
If you want to know anything else then ask
Sony Xperia S was my first android
Had a nokia brick before (3310)/N95)

Before unlocking the bootloader , I'd like to backup everything with CWM or Xrecovery or nandroid ,
I tried installing CWM but it said my phone was not supported, so I gues I'm on the wrong place, so could you point to the right CWM?
Also, CWM I think recovers only the ROM and the kernel but no system applications, any app to do that and save everything to my PC?

As you suggested DRW Backup tool I will probably go ahead and unlock the bootloader, the only thing is now that I'm stuck at the backup point,
Before flashing the ROM or any kernel they say "backup", and it's used CWM or other tools, and when you go to install CWM they say backup first before installing...
Am I missing something here?
It's like a loop but no solution on how to backup what it's currently installing before putting any CWM or flashing a kernel...
How did you get out of this?

hey mate first of all backup ur TA partition....then unlock ur bootloaders.....then u can flash any custom kernel with CWM recovery......from recovery u can flash any custom rom or mod .zip file.....
UNLOCKING ur bootloaders voids ur warranty so always make a TA backup before unlocking.....u can search various thread for root,unlocking bootloaders,flashing custom kernel,custom roms within the thread.....
Hope this helps.....

Yep, thanks that's all clear, what I wanted to know is how to backup everything before installing any custome kernel/ROM or Recovery tool (CWM, Xrecovery, etc)..
