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?

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
hello every body

No, it's not possible, ftf. files can only be made by Sony, so you've got to do always the same prodecure for flashing, rooting,....

thank you so much for your answer

That's a really tedious procedure you're following. When I try a custom ROM and don't like it, all I do is:
1) If switching between an ICS ROM and a JB ROM and vice versa, reflash the kernel, then reflash the ROM.
2) If moving from one ICS ROM to another, or one JB ROM to another, just reflash the ROM.
3) If moving from ICS/JB to GB or vice versa, flash the stock ROM, flash the kernel, and then flash the custom ROM.
You don't need to keep on flashing the stock ROM, rooting it, installing CWM, then installing the custom ROM. Kernels, as far as I know, usually come with recovery installed. If you're in a bootloop, just follow the pertinent steps from the list outlined above.

Go read the stickys, get some basic knowledge and learn something for yourself, then ask questions about what you don't fully understand, on an existing thread that you found while Googling.
bootloader locked or unlocked because it sounds like you have a locked bootloader, if it is unlocked then why dont you flash a kernel eg. kernel rush with CWM already on it ?

You don't need to install CWM again, even if you're in a boot loop. Once the phone reboots, keep pressing the "down" volume rocker, as you always do, and you'll enter into recovery. If you're moving to a different Android version (for example, ICS to JB), switch off your phone and flash the appropriate kernel. Then all you need to do is reflash your previous ROM or flash any other ROM that you want. However, that's only possible if you've download your previous and/or other ROMs onto your SD card, too. Do you do that before you flash?
I don't have any experience with locked bootloaders, but the user above IS of the opinion that you might be on one. If that's the reason you're having to go through so many steps to flash a ROM, why don't you try unlocking the bootloader of your phone? I'm more than certain your phone's not covered under warranty anymore, and unlocking the bootloader is definitely not going to fry your phone or anything of the sort.
Hey friends,
I finally managed to brick my device (c6503).
Had it on resurrectionremix and wanted to go to lineage. After that didnt boot i tried some older CM12/11 builds and finally lost my recovery whith flashing an aosp rom...
I decided to go on stock using flashtool, and now here I am, looking as stupid as it gets
Tried various ftf's using flashtool, always resulting an a black screen after the sony logo. now i dont know what to do next.
Your Help is much appreciated

I was able to find a solution myself. I flashed some Kernel which included cwm via flashtool. I was able to boot into this recovery. Then I used ADB sideload to install CM14.1 unofficial and voilà!
I hope this helps anyone having a similar issue.
Regards!
Were you able to return to ROM STOCK ??
I'd like that, but unfortunately I could not, even flashing a custom recovery on it.
I would like to go back to ROM STOCK, do you know any tips?

I have a similar question, I appreciate your help if you can.
Now, I have 7.1.1 Nougat from XOSP , and it works well. I'm trying to restore the official kernel from Sony, using Sony's Emma, to make some tests. When I flash the package from Emma onto C6503, it won't turn on, just show Sony Xperia logo and then black screen. Do I need to flash other packages ? I thought the Sony's official kernel has all things to put it back to near original form.
Thanks!
I have Installed RR-N 20160312 then revert to stock LL, then Only Sony/Xperia Logo. Then I ask some question, they say Flash Kk, successfully flash the Kk build. But unfortunately, My Internal Storage Cannot Read. I think that was the Problem why flashing LL just make it only Sony Logo, No Bootamation. Still finding a workaround to fix this

I was not able to return to stock Rom. In fact, I tried to revert to stock today by simply flashing it with flashtool but got the same "black screen after Xperia logo" issue as last time. I would like to return to stock in the future, but for now I dont know how and I dont think there is anyone dedicaded to fix this issue right now.

Well, just got back to Stock 5.1.1.
Followed the idea posted by Kran007:
-Coming back from CM14, used EMMA FlashTool, that resulted in the famous black screen
-Flashed stock Kit Kat FTF using FlashTool (not EMMA) with unlocked bootloader (should work perfectly fine for locked bootloaders as well) and started the phone correctly.
-When back to FlashTool and locked the bootloader, just in case.
-Used PC Companion to update to the latest build available, only works with locked bootloader i think
It's not the best solution, it isn't the fastest either, but it works!!!
Hope this can help anyone...
Just flash stock 4.4 kk firmware using flashtool. Yes, it needs a lot of work to go back to stock LP, root and have recovery but it is the best way when you flash custom rom with nougat and above. I don't face again the problem of not accessing internal storage ☺
