Hello, I have installed CWR from rom manager and I have made several nandroids backups.
There were no errors, so I thounght it was everything ok. Yesterday I tried to restore a backup of the CM7, and it freezes on the LG logo.
Then I tried with a restore of the stock rom and happens the same.
I used the fix of Paul Obrien of back to ext3 and then the restore, but I am not able to restore any nandroid I made...
The only way was intalling again everything starting from zero...
Anyone with the same problem??

I have made a CWR backup of my rooted 1.1 stock rom with all my installed apps. I tried out the new 1.2 update and then tried to restore my backup. Everytime I connect to Wifi I get a message about problem authinticating and having to reflash to stock. How can I get my backup to restore correctly? Wipe data/cache? Won't that take out all my apps? Or am I stuck going back through 1.1 stock, autonooter, install apps/titanium restore?
Hi,
I hope that my experience could help other persons that fall in my situation.
After a try of CM, I couldn't restore my stock backup anymore, the phone hanged up in the lg boot screen.
There were no problems about ext4 partition or wiping or fixing permission.
I was thinking to do a NVflash procedure, but i gave another try: using old modaco CWM recovery. I overwrited CWM 4.2.0.2, performed a wipe, installed the modaco zip ext4->ext3 (i didn't remember if i was ext 3 or 4) and then restore my STOCK backup: EVERYTHING WAS FINE!!!
Maybe there's a problem in the newest CWM during restore a backup, i don't know, but in this way i could restore my original firmware.
Hope that this could be usefull.
Did you do your stock backup with modaco CWM? It has different MD5 checksum than the CWM. Might be the case why you can't restore your backup.
No, I did the stock backup with the original CWM.
I think that the problem is in the restore procedure of the original CWM (4.2.0.2), in fact also the CM restore is impossible, only if you install the zip immediately after the restore. Instead... hangs up.
I find when that happens the best method is to reflash the rom your restoring and just restore the data from your nandroid backup. Always works for me.
confirm this issue with cm & nandroid restore

This is true, restore and then install the rom. But how if your restore is the stock rom? NVflash? It's not the same.
Fortunally, Modaco CWM solve it without this procedure.
Thanks!!
This solve my problem with my stock nandroid restore. I downgrade CWM to 3.1.4 (did the backup with 3.2.8 version) and now works perfect!!
Finally i could restore my stock rom.
my solution was...
1. nandroid backup of mcr
2. full wipe & installed cm7
3. nandroid restore of mcr
4. installed mcr without wipe (this solved bootloop after restoring)
I've made a nandroid backup of my rooted stock Rom with cyanogen recovery and flashed Modacos FR15 wich worked retty good for me. But after some testing i wanted to change back to my stock Rom. After doing backup of the Modaco I wiped and restored the stock rom backup which refused to boot. I restored the modaco Rom which worked perfect. Any ideas what the reason could be? BTW md5 check before restore was all fine and no errors on restore.

Did you wipe everything? Also Dalvik cache? It worked for me tho, what kind of version are you using for CWM?
CWM is 3.0.2.8 (latest version which i installed via ROM Manager) - as I said - other backups of CM Nightly and Modaco FR15 worked without probs. But I made 2 Backups of my rooted Stock ROM v10c which refuse to boot after restore :/
Wiped all except Dalvik - I thought Dalvik gets wiped when doing Wipe Data / Factory Reset ... but I will try again with wiping Dalvik too.
I tried again to restore this time with dalvik wipe - but no change - boot hangs at the LG logo with the grey/blue loading-bar, the bar is moving some seconds and then stops and nothing happens. :/
try to press power+vol down to reset the phone to factory default. see if it can help...
I've had similar problem.
phone wont boot.
Only way I found out, you can see here:
http://android.modaco.com/content/l...rom-release-v10b-dated-1300166062-15-03-2011/
but you will loose everything what is on your phone
The reason it won't work, is because MCR converts the file system to ext4 (which CM7 can cope with). To revert to stock, you need ext3 - either
1. Use this to convert back to ext3 and immediately restore the backup (don't reboot or it will go fubar) http://android.modaco.com/content/l...3-for-converting-your-device-er-back-to-ext3/
2. Use nvflash to restore the stock 10b, then flash Clockwork, and then restore your backup.
The choice is yours .
I have seen the same issue on other models forum but could not answer my problem.
Whenever I restore a Nandroid backup using either ROM manager or CWM recovery, all goes fine but on reboot I am stuck on the 2nd LG logo.
The only fix I found is to restore the ROM, pull the battery, boot into recovery, re-install CM7 from the SD card.
This happens will ALL the backups I made while on CM7.
I can however restore and boot the original LG ROM I backed-up after rooting my phone.
Am I doing something wrong?
Thanks.
LG Optimus 2x
CM7 nightly 39 (but had the same with previous versions)
ROM manager premium 4.3.1.3
CWM recovery 3.0.2.8
Try wiping all caches (including dalvik in advanced) and fix permissions. Also you can try CWM 3.2.0.x (you have to install it manually, Rom Manager does not let me download it)
If u restoring nandroid backup of cm7, flash cm7 rom after u completed restoring backup then u reboot.
1. Restore nandroid backup
2. Flash cm7 rom
3. Reboot
I did wipe all, but it did not help.
I am not sure about CWM 3.2.0.1. I will give it a try.

This is what I am doing, but why do I need to reflash CM7 after a nandroid restore?

I did a nandroid with my fr17, restored it and it wouldn't boot correctly, so i reflashed it without the wipe and it worked, maybe some system file wernt correctly backed up, hope this helps

It was a problem with the boot image not restoring properly (or at all perhaps), this should be fixed on CWM 3.2.0.1 (and possibly 3.2.0.0)
Thank you Rusty (and mikee2185).
Installed your 3.2.0.1 and it worked fine!
Cheers.

Great both of you rusty & pa64. I was facing the same problem with stock ROM restore with a certain version of CWM recovery. Rusty's 3.2.0.1 saved the day for me and restored successfully from the same backup which the other CWM version failed. Thanked both of you.
thanks temasek
it worked.
I had made a backup before install other rom. After this I install this rom http://xperiadroidx.blogspot.com/2011/12/rom-android-237-gingerbread-xperia-x8.html . Then I back to GingerDX by restore backup. But after reboot it stops on bootscreen. I don't know why. Anyone can help me with this? One week ago I made backup and it's working fine. Is there any error in the newest backup?
