[Q] SOLVED - Cannot restore Nandroid backups. Phone stuck on LG screen.

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.

When restoring with cwm

When you restore a backup with cwm do you get all your apps back?
And what exactly does it restore?
The only time i tried the restore function was when i flashed ics but it was a gb backup and i got an error .so help me please

If u want to restore a gb. backup when on ics, u need to flash gb. Kernel. then u reboot directly into recovery(advanced/reboot recovery) and restore your backup.
And yes all your apps and settings will also be restored.

thank you..putting a gb kernel wont brake the phone?

No, bootloader on i9000 ics roms is ginger. And you don't have to wipe anything.
if u know witch ginger kernel u were running,flash that kernel and restore your backup
But DON'T boot up your phone. Just reboot into recovery from recovery and then restore your backup from the ginger kernel.

Can you backup custom roms? Because im having trouble.
Yesterday i updated from dark knight v3 rom to v5.5 and backed up the rom through recovery mode because rom manager wouldnt work (kept getting the android guy on its back with an exclamation mark)
I decided to go back to v3. I booted into recovery, wiped date/cache then restored my backup rom. When it finished, it stuck at the boot animation for 30 minutes. I pulled the battery and tried to boot into recovery but it just kept rebooting until i took my fingers off the up+power the proceeded to animatiin where it would just hang..... did i do something wrong?

If you have already taken a backup then go to CWM-> backup and restore-> restore the backup..

it's still stuck on galaxy ace screen did a full wipe, format cache, data, system, sd ext and restore my backup. On mount and storage, why does it says "unmount /cache"? Maybe it has something to do with that?

If you've flashed a CM7 rom there's no way to restore a stock rom from backup taken through CWM5. The filesystem format is not compatible.
You'll need to flash stock from Odin.

Yeah, flash a stock firmware with Odin and then when you have done, install cwm recovery (because installing a new firmware erases everything so also your cwm recovery that you had) and try to restore your backup.

*HIT THANKS IF I HAVE HELPED YOU*

Wipe everything then re-flash ROM.
Reboot before flashing anything else.
For stock rom, go to download mode (power+home+vol. down) and connect to PC.
Get stock rom and ODIN.
Check out guide to using ODIN: ODIN for Dummies

format all wipe all install this:http://forum.xda-developers.com/showthread.php?t=1962762

You can not recovery stock rom over a CM 7 because the last one reformat the internal partition to EXT4 uncompatible with stock rom. So flash a stock rom with ODIN (possible the same you used for the nandroid backup) than restore.

I think you need to do a full format using ODIN..and reinstall CWM and install CM7 and try to recover your backup from CWM.:good:

[Q] I need some help to get back to Ultimate XXLSZ

I was using Ultimate ROM XXLSZ_JB_4.1.2_v5.2 without any problems apart from poor battery performance.
However, I attempted to install Rocket ROM-V1-XXLSZ and have now got myself into trouble.
I followed the instructions to flash the latest XXLSZ-OXA cwm kernel and then flashed the Rocket ROM. It worked ok but I would like to return to the Ultimate ROM and kernel I had before.
I have a pevious full Nandroid backup of the phone (made with ROM Manager Premium) of the Ultimate ROM and the PhilZ kernel it came with but cannot restore it. I get the error "MD5 Mismatch" and the restore aborts.
Even if I reflash the original Ultimate ROM with all the usual wipes, the XXLSZ-OXA cwm kernel is still there and I still can't restore from the Nandroid backup. I tried re-flashing PhilZ 3.1 kernel separately and then the Ultimate ROM file but this didn't work either. The kernel is still the same.
Can anyone tell me how to either
1. completely wipe the phone so I can install Ultimate ROM AND the built-in PhilZ 3.1 kernel.
OR
2. get the phone to the point where I can restore from my Nandroid backup which I assume will restore the earlier version of the ROM at the same time.
I hope I've explained the situation clearly enough.
Thanks in advance.
Trevor

Install a cm kernel then wipe your phone then install a fresh ultimate rom and later on advance restore the data

Go to cwm/backup and restore/misc nandroid setting/ untick md5 check. And try to restore again

You don't want to restore your nandroid. It is a bad backup.
In philz recovery go to mounts and storage. Format system data preload cache. Them go to advanced from main page and wipe dalvik
Flash ROM. Guaranteed to work.

Thanks. I know I can flash the ROM again but I was hoping to learn why the Nandroid backup no longer works.
Since posting, I gave up trying to restore the Nandroid backup, did all the usual wipes, re-flashed the Ultimate ROM and re-installed all my apps from scratch so my phone is more or less back to normal (Incidentally, I notice that no matter how many times I do this, all my music and photos are still there even though they're stored on the internal sd card. Dunno why).
Most of the ROMs I've tried have the kernel built in so all I needed to do was do the usual wipes and then flash. If I didn't like the ROM, I just wiped again and restored the Nandroid backup using CWM (Vol Up + Menu + Power) and the phone was back to its previous state.
The only thing I did different this time, as per the Rocket ROM instructions, was flash a kernel first. I may have done something wrong with that step or messed it up somehow. Even when I flashed an earlier version of the PhilZ kernel, the restore still didn't work. I've still a lot to learn about ROMs and Kernels, I guess.
As I said, I have successfully restored from Nandroid backups many times before this without any problem after experimenting with different custom ROMs. Can I ask you why Nandroid is a bad backup? Is it a problem with ROM Manager?
(One problem I've always had with ROM Manager is that if I choose to write the backup to the external sd card, it falls over with error messages. If I choose the option to backup to the internal card, it works but writes the BACKUP TO THE EXT CARD ANYWAY! I cannot get a reply from the dev about this).
Is there a better, more reliable backup method you'd recommend that does the same thing as the Nandroid?
I notice that different ROM managers use different CWM Recovery versions ie ROM Manager Reboot Recovery = 6.0.1.2, ROM Toolbox Rebooter = CWM 6.0.2.8 (same as Vol Up + Menu + Power). Could that be part of the problem?
Sorry for the long winded post.

[Q] help? strange corrupted file/folder maybe

okay, I upgrade my n70f00 from ics stock to jb stock then root with philz kernel. everything went fine. then I notice my phone a bit slow, memory almost full (left less then 100mb out of 800mb) and everytime I boot I get 'android is upgrading, app statting.." notification. i want to reset, but when I do backup with cmw always fail (never backup before). do some this and that, i found that i can't access folder '\data\lost&found'. each time I click that folder using any rooted explorer I have the phone restart. I search and found sgs tools app that can delete corrupted media file, and it did. but I still can access '\data\lost&found' folder (keep restarting).
any idea at all?
thanks in advance..

Did you wipe all the partitions before flashing jb? You can download philz kernel (zip file) corresponding to your rom and flash it from stock recovery.. Go back to recovery (cwm) and wipe data, preload, system, cache, dalvik cache and put the phone in download mode and flash jb for your country or any country using pc odin.. Do backup anything important before wiping..

I didn't wipe anything prior to jb upgrading, hoping everything went fine so I dont have to reinstall alot of apps after upgrading. Now, I can't do full backup because it keep rrstarting when I do full backup. So I'll try several things before doing full wipe and odin.
Thanks

if you are already rooted and if phone gives you enough time to backup your apps you can try using Titanium backup pro to backup your apps.

yes, I'm root. ok, i'll try that. btw, is there any risk of bricking if I do odin with 'corrupted' system folder ('system\data\lost&found')?
thanks again

No. If you put the phone into download mode and flash stock rom from pc odin it should work, but it is advisable that you do wipe the /system /data /preload before you flash stock rom again. Make sure you are on safe kernel before wiping.
