Hey guys. I have a question. I have flashed mcr rom on my o2x recently but before flashing, i saved a backup in cwm.
Now that i want to flash back to stock rom and kernel and the exact same original settings and rom, can i just restore using cwm or what do i do?
I am from Singapore using Starhub.
Thanks guys

The main problem is that MCR will have converted your partition to ext4, which the stock ROM can't read. As far as I understand, there are two options
1. Use http://android.modaco.com/content/l...3-for-converting-your-device-er-back-to-ext3/ but make sure you have the backup on your SD card, so before you reboot, you can restore it (if you reboot without restoring, bad things happen).
2. Use nvflash to put the stock ROM back on, and then restore your CWM backup.
But. . . someone who has done this may be able to confirm - if you want to be extra safe, check in the MCR thread.
Thnks for the reply! So cwm is actually not really a rom backup image?
Sent from my LG-P990 using XDA App
It is, but because the disk format is changed when you install MCR, I don't think you can restore it, without changing the disk format back first (I guess it depends how low level the image goes, maybe?)

Pretty sure NAND restore would be fine.
I see.
So by right what i have to do essentially is to:
1. Convert back to EXT3.
2. Make sure my NANDRIOD backup is in SD Card.
3. Off phone and go into CWM then recover NANDRIOD.
Should be all?
Don't quite understand the nvflash. May i know what is that?

When you do a backup via ClockworkMod recovery, are the efs files included?
e.g. Theoretically would restoring a nandroid backup fix a broken IMEI?
I've searched and found conflicting reports.
Many thanks
push it really would love to know if it would restore it!

it really depends on how you made your nadroid back-up.
there are a couple of options when doing a nandroid back up.
if you select the "ALL" method then it will back up your system files as well as your EFS folder.
go try making a back up to see it for yourself via cwm.

Thanks for your reply. I tried to create a backup, but it seems my recovery is 3e rather than 2e so I can't. From what I've read I need a modified kernel with 2e. Does that mean I need to risk a flash before I can even backup?

wait.. back up a bit.. you said your were using clockworkmod recovery.. but now you're stating that you are using 3e recovery.
i was giving you instructions on how to do a nandroid back up in cwm recovery. i haven't touched 2e and 3e in ages.
go get cwm recovery and do the back up there.

If you look at the list on the 1. page, there's no efs.img, meaning you don't have a backup of /efs.
I think in order for cwm to take backup of efs, you have to use the newest custom kernels, as they include cwm customised for I9000. If you use the backup option on Rom Manager you'll have problems later.
I see i just scripted it to my pc and external sd perhaps thinking about putting it in a swizerland vault ;-)

ClockWorkMod Recovery does not support backing up of /efs partition yet. You should do it manually.
Is it possible to extract only /efs from the nandroid backup and more important to me, will an "old" backup do the job to restore an imei.
Re efs backup
Use online nandroid manager it backs up efs and whatever else you want. You can choose or let it do it's thing. :cyclops:

quite a bit of time past this post, so does CWM supports /efc backup when I do nandroid now?

If you backup whole build, yes it does.
It is nevertheless a good idea to backup your efs folder separately, by using ADB or with terminal emulator.
If you have been using a EXT4 ROM and you want to restore a stock ROM that only has EXT3 support, it's a bit of a faff. Introducing BackToEXT3.
This ClockworkMod update zip simply converts your /system, /data and cache partitions back to EXT3. It wipes them both in the process, so you need to have an existing backup / ROM to restore to.

After installing FR12 custom ROM Vanilla Edition on my phone, I wanted to get back to stock so I installed - back to ext3 zip. Then when I tried to restore the stoc ROM, I got the error MD5 mismatch!
I want to specify that I tried a custom ROM before but with ext3, and I had no problem to return to the stock ROM.
Tool worked fine for me. fr10 back to stock.
Md5 error probably means ur nandroidbackup is damaged

What "img" are you talking about? Nandroid restore is for restoring a previous backup, not for flashing a rom image.
If you want to flash a stock rom image, you need to use smartflash or nvflash, unless you want to flash the 0622 one, which someone made available in CWM format. (Not completely stock though, as it is prerooted etc.)

You don't need that. CWM automatically converts from ext3 to ext4 (if the backup is ext4), but not the other way round.

I don't think there is a way. It's faster and easier to backup apps + data to the sd card ( not internal storage) and reflash.
You need to flash back to stock to remove CWM recovery.
Here's a link to the message thread with links and directions. http://forum.xda-developers.com/showthread.php?t=1104093
If you have a WiFi only Streak be sure to read starting with message 30 for the links and directions to get back to stock. I used this method and it works great.
As was already stated be sure to back up to the SD card before starting as your internal storage will be replaced with stock images.
Hi,
I used CWM to backup stock rom(2.3.4), then I used CWM to try CM7.1 nightly. Now, I would like to go back to 2.3.4. I restored the backup rom. The step i took was:
full wipe
format /system
install http://nigella.modaco.com/files/r2-backtoext3-2x-unsigned.zip
restore backup rom
reboot
After that, I rebooted. There is bootloop. Just wonder if anyone know why and how to solve this? thanks in advance!
When you get back to stock lg from cm you must format all ext3 before restoring. Search for Dr4go tools.

I tried to use r2-backtoext3-2x-unsigned.zip to restore it.
Can you tell me the correct procedure?
1. enter CWM mode.
2. install r2-backtoext3-2x-unsigned.zip
3. full wipe
4. format /system (i think i dont need this step, right??)
5. restore 2.3.4 backup
6. reboot
Is this correct?
Maybe i should try to use Dr4go instead ofr2- backtoext3-2x-unsigned? thanks
Very simple:
1. Cwm install ext3 zip file from Dr4go
2. Cwm restore your stock backup
3. Restart

The bootloader is the first program which starts the phone (or any computer), ext3 and ext4 are different data mgmt systems.
Your case is old bootloader, the new bootloader was introduced by LG with ICS roms. But this is another story.

Have you tried flashing your same ROM again if you were on a custom ROM and then superSU.zip then wipe cache and dalvik but don't factory reset(trying to save your data), then reboot.
If that doesn't work we'll take the next step.

A custom kernel is any kernel that isn't stock.
If you're using custom ROMs you're using custom kernel, find a kernel that works with your ROM.

No, custom ROMs can't use stock kernel so they need their own kernel, the kernel is what integrates your hardware with your software, roughly equivalent to drivers on PC. Without the kernel, the device can't use the ROM.

Yes, that's how some newer Samsung are having to root.
If you're on Stock firmware then you may have to find a custom ROM and flash it or flash your stock firmware via Odin and start over with rooting the device again but you'll lose your data.
You might can do a nandroid backup before you flash anything and then after flashing you can retrieve your data from the nandroid backup by extracting it and putting it back where it belongs.

Answer 1) to prevent this in the future, when you get straightened out, boot to recovery and make a nandroid backup, that way you have a backup of everything with it working correctly that can easily be restored later if you have problems and will put you back to having everything the way it was when you made the backup. Its like a restore point in Windows.
Answer 2) A nandroid backup backs up everything on your device that is important, all of your settings, your contacts, your ROM, everything. You can pull whatever data from the backup that you need. But the backup I'm telling you to make right now nay not keep everything you had, there's no telling right now how much data you've lost or not so making the backup is to save whatever you can so you can retrieve it after repairing your device.
Always make a backup after every major change you make on your device so you'll always have a backup that includes the new additions so you can restore to that point if you need to. When you make a new backup you can delete the old one unless you just want to keep it but the more backups you make the more room they take.

Don't get ahead of yourself, for now just make the backup and then focus on getting the device restored to working again and THEN you can worry about retrieving the data.
One step at a time, stop trying to cross bridges you haven't gotten to yet.

Never mind then, just keep it on PC
Now, look through your forum and find a custom ROM that works on your model number and a compatible gapps package(the ROM thread will tell you which gapps you need so don't ask) and then flash ROM then superSU then Gapps in TWRP then reboot and see if you're fixed.
If that doesn't do it then you'll need to go to Sammobile.com or samsung-updates.com and type in your model number to find your firmware, download it and then flash it in Odin in the AP slot, the same slot you flashed your kernel to root.
