Hi all,
I installed CM9 on my Xperia Neo V using the instructions on the wiki.cyanogenmod.com/wiki/Sony_Ericsson_Xperia_Neo:_Full_Update_Guide. Now I'd like to go back to standard firmware in order to use HDMI out and other features.
I made a backup with CWM. Can I simply restore it with CWM? Will that restore the original kernel as well?
Or do I have to use flashtool to reflash the standard firmware? And if so, do I have to download one from here or can I look for the latest official version from the local Sony Ericsson site?
Thanks all. I searched and read a lot but I wanted to be sure before I go ahead.
Restore ur nandroid backup, or flash official firmware ftf file through flashtool... Download ftf from XDA forums..
i think it is better if u can flash the official frameware using flashtool...
Thanks, I'll do that. That won't relock the bootloader though now - will it? So if I want to go back to a custom ROM it should be easily done with fastboot?
Thanks again for the replies.

No, that won't relock the bootloader though.. Flashing firmware just makes your phone go back to the official stock ROM..
And if you want to go back to a custom ROM, then flash the appropriate kernel through fastboot and then install the ROM via CWM!

Hi, same question here. However, I only have the backup made in CWM at hand and it is quite urgent. It is of a fresh install of the original ROM. Will that do? Which settings should I choose to restore, what should I wipe etc.? Happy about any hints.

You don't need to do anything extra when restoring the backup, just go into recovery.. Backup and Restore and then restore your backup..
No wipes are to be made since it will restore your device to the point of your backup, in your case your original ROM..
Keep in mind that if there's a custom kernel right now, it won't restore the stock kernel.. Just the ROM

Great, thanks for the information. So to also revert to stock kernel do you by any chance know where I can find it? And should I flash it (with CWM?) before or after restoring the nandroid backup?
EDIT: I found MT11i_4.1.B.0.431. That still leaves the question about the correct sequence.

Since you're restoring the stock ROM, custom kernel won't do any harm..
But if you want to revert to stock kernel then they should be in the General or Development section (I am sorry I can't point out exactly where since I don't own this phone anymore)
And yes, stock kernel that you'll find in the threads would be of ftf format that can be flashed only with the help of flashtool..
Kindly read the instructions of how to use flashtool if you're unaware of this!

Okay, good to know!
Just lock your bootloader.Then flash stock firmware (.ftf) file via Flashtool.
I don't recommend CWM restore.

Flashing can be done on an unlocked device too..
There's no need to relock the bootloader!

No sir,
I have flashed more than a dozen times for both my Neo V and Xperia P with their bootloaders unlocked.. I haven't encountered any problem and neither has anyone..
It's false what you're saying!
That's true, no need to relock the bootloader :thumbup:

Same here, ftf flash with Unlocked Bootloader NO PROBLEMS!
So I had this rom (http://forum.xda-developers.com/showthread.php?t=1876792) and i wanted to go back to my official rom. I went to CDW wiped out system, date, ect etc and I tried to restore my backup which I did with my CWM before I use the custom rom. Everything ok but when I reboot me device it shows the bootlogo of the custom firmware and not the sony and after that it goes black. How do I solve this? I searched but I didnt find anything
Please be more exact on what you wiped and formatted all. What kernel and cwm version are you using? Did you made the nand backup with the same cwm version?

And you flashed back stock (based) kernel?
When you flash .ftf rom using a flashtool, it flashes all official components (rom, kernel, baseband) by default. I apologize flashtool is a most useful method to go back at stock rom. What do you think?

Download flashtool. Download ftf of firmware u want to flash. Open flashtool and drop that downloaded ftf file in flashtool window. Then check no final verification. Click ok. Then follow instructions given by flashtool. Done. Simple as that.

And be careful with device drivers. Install it from a Flashtool folder to avoid a flashing problems.

One last thing, as I said in my first post before i go to jelly bean i made a back up using CWM(The backup was on official ICS 4.0.4 + rooted + BL open). If I want to go back at that backup the only thing i need to do is go to CWM, delete system, delete data, detete etc etc and I do the restore?
Or I need first to flash a kernel for ICS and THEN restore the backup? Im still kinda confused with the kernel thing and the restoration...

Yea. Cwm doesn't reatore kernel. Just the system, data dalvik etc.
You'll need an ics kernel like alliance or suave to boot into the restored backup.

So that was the problem. I can use any ICS kernel or the official kernel( because the backup was on the official rom even though it was rooted) ???

Any kernel compatible with Stock ics

I recommend you to flash a kernel that has been used at time you created a backup, because I had a problems with Wi-Fi when I do «hot-flashing« from suave kernel to night - elf.

If I format system will it delete the backup?
Also If I install stock kernel back from custom kernel then do I have to install CWM again?

The backup stays on the memory stick so copy it in your pc in case something happen
No you will still have cwm

If you used cwm from kernel, then yes, after you flash stock kernel, you will need to instal cwm to system.

From where?
I highly doubt that someone with custom kernel would go and install cwm in system.
Guys,

Yes, it can be done download the original firmware of your phone and flash it as flashing some custom rom.....

Download the .ftf file for your particular device from above thread... And then just flash the downloaded file by flashtool...
You will loose your root (bootloader will remain unlocked if you unlocked it previously)

Hi I've flashed my s2 with sentinel rom (basically cyanogenmod) so it's like a nexus 4 and I would quite like to flash a stock rom but not like the s2 rom like is there a way to flash an s3/s4 stock rom to my phone? :thumbup:
Sent from my GT-I9100 using xda app-developers app
No. Pls don't flash a rom that's not made for your phone as you will probably brick it. Look in Android development for what you want
I double dare you to try it.
Is there a way that I can go back to my original stock rom test it out and if I don't like it go back to my flashed rom?
Sent from my GT-I9100 using xda app-developers app
Hi,
Make a nandroid backup from you current rom und flash an other rom. If its not fit you can restore your backup
Maybe you have to flash the kernel that you used to make the backup before you restoring.
Basically I want jelly bean but the stock version. Currently I'm using a rom that is jelly beans but is like a nexus 4 but I want the Samsung features. Thanks
Sent from my GT-I9100 using xda app-developers app
Hi,
i know, you wrote on OP sentinal rom. Just make a backup from your current rom in the recovery. And then you go to the download modus and flash a stock rom via odin. If you dont like it, flash a recovery and restore your backup.
Easy
Ok! Where can I get the stock rom from and can it be jelly bean? I know that when you buy the new s2s they have 4.1.2 installed! And how to you flash a recovery? Everything else I know.
Sent from my GT-I9100 using xda app-developers app
Okay... do you flash the sentinel rom oder someone else? If you did it than you have to know what the recovery is. It the menue that comes up when you hold VolUp+Home+Power and boot. There ist an option "Backup and restore".
Here http://www.sammobile.com/firmwares/ you can get the official stock roms, just search for I9100. To download you have to register, its free
Andi
Get your stock rom from samfirmware. Just scroll down and download the required Android version. You can get temporary recovery from recovery tools in play store or if you want permanent recovery you gotta flash a custom kernel.
Guys...

Flashing from a custom ROM usually does no harm. Provided you flash it properly with proper data clearance. And in some cases you have to flash the stock rom before you can continue to flash the new ROM. If you have not taken a backup of your stock ROM, you can download your stock ROM from your device forom.

Most of the times you can flash like this when you want a new rom. Delete /cache /data /system (you can also wipe /dalvik cache from your recovery then flash the zip file and google apps and what ever you want to flash from recovery. Hope it helps. Good luck!
It doesn't matter if you're a custom ROM. You can download a new custom ROM and go to the recovery and do the 3 wipes (factory reset, cache partition, dalvik cache) and just install. Make sure you make a nandroid backup before wiping and doing anything!

Nope. I never do that! But be sure to clear all data and so on. It is completely fine if you are on a stock based ROM.
