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.
Hey guys,
I used odin to get boot it back up and then I used ClockworkMod to restore backed up data....
After phone said 'restore complete,' I let the phone reboot, but the phone will not reboot
at&t screen pops up and then black out then pops up again then into android recovery mode.
Any ideas?
Could you please provide a little more information about how you got to where you are? (e.g. what rom/kernel/modem/theme you were flashing, what ODIN you used, what version of CWM, etc.) Anything you provide will be helpful in troubleshooting.
Well I had cognitive 4.5.3 installed and I tried restoring using clockmod recovery
the restore wasn't successful and the phone would stay black screened after Galaxy S logo screen
So I turned on odin3 and put my phone on download mode then hit start on odin3
that successfully restored the phone to froyo 2.2 without any of my data
so I tried using clockmod recovery once again to restore the backup
and then... that's where I am
The phone won't boot. It will just go into recovery mode
Here's the message I got after trying to restore once again
--------------------------------
ClockworkMod Recovery v2.5.1.2
Checking MD5 sums...

Restoring datadata...

--------------------------------
When did you make that nandroid backup? If you made it while on stock, you'll have to go back to stock first, then run the restore command. If on cognition, you'll need to be on the version you were on when you made the backup and restore there.
Here's the link I found on how to return to stock rom
http://forum.xda-developers.com/showthread.php?t=731989
I've done the first part - before the master reset and then tried restoring the backup and that is how I got to where I am right now.
Do I need to factory reset as well?
If I do factory reset, won't that erase the backup file?
Thanks. I really appreciate your help

To answer your question, doing the master clear will erase EVERYTHING stored in the phone's internal memory. Don't do that step now, as you should be able to get out of where you are without doing that.
I think where your problem occurred is that at some point you made a nandroid backup in CWM, and by trying to restore that on stock, it's freaking out. If you can remember what ROM setup you had on your phone when you made the backup, you could try to get back to that setup to use the restore option in CWM.
Before doing any of the things you're doing now, had you made a backup in Titanium Backup?
I do have backup made with Titanium Backup.
apps data and everything that I could backup with Titanium Backup
Will restoring what I had backed up with Titanium Backup and then restoring the system using CWM work?
I am currently at 2.2 Froyo, which was the rom I was using when backing up using CWM
You've flashed 2.2 stock? If so just flash the rom you previously had with cwm then let it boot. After it boots reboot into cwm then perform a restore in cwm. If that doesnt work nand backup might not be good and you will just have to flash stock again and just rub tibu and leave it at that.
**Thing about NAND backups is that you have to use the same system when you restore (i.e. you nand backup usng cognition then you flash another rom when you nand restore its not going to boot).
Thanks guys for the suggestions!
My phone has been saved!
Hello,
I need to know before install Overcome & CWM if it's possible to backup my stock KERNEL. Currently i have 2.6.36.3 kernel.
I think that is better to restore with the original kernel if need to use tha warranty one day ?
So is it possible to backup or download the stock KERNEL.
Thanks a lot for your help.
before you do anything get a nandroid backup and save that original nandroid backup.
Nandroid Backups are a full ROM backup, that means:
Radios
ROMs
Kernels
User Data
Trying to claim a warranty after you violate the terms and services isn't the most honest thing to but if you intent to cheat the warranty system that just hold on to your backup. A nandroid backs up everything
Hi,
Thanks a lot for your reply. For the warranty I am okay with you regarding the honesty.
About the Nandroid ROM backup, i read somewhere that full backup must be done but it backup all except the Kernel !
I am little bit lost :
1/ The KERNEL Backup can be done with Nandroid backup ?
2/ Can we make Nandroid backup with stock ROM & stock Kernel (fresh TAB) ?
3/ The CWM is it a Kernel ?
Thanks a lot.

CWM stands for clockwordmod, its a custom recovery. You need a custom recovery before you can start changing things about your tablet. It is Not a kernel. Think of a car. A kernel is like eh engine, the recovery is like a toolbox. Its more complicated but thats the idea. The stock recovery is too limited, which is why we have custom ones
When you do a nandroid back up it backs up everything. When you do a nandroid back it backs up the kernel as well as the ROM all of your settings and app data. All in one.
If you want a stock nandroid Do it first thing after you have a custom recovery. A nandroid is saved in the clockwordmod folder. Then save that file somewhere safe. Flash drive computer t whatever.
Hope this helps

Here is the Flashable zip for backup your Old recovery and kernel
First, You need root
From your stock recovery, Flash backupkernelrecovery.zip.
Approximately 30 seconds, backup process will make a folder "mybackups" in your SD card,
Reboot as normal, and Open "My Files" and see folder "mybackups"..
You'll find 2 file recovery.img(your stock recovery) and boot.img (stock kernel)
For Restore your recovery.img
download overcome cwm from alterbridge86 thread, unzip the file and replace recovery.img from that files with yours..zip again and flash from recovery, reboot and you got your old stock recovery..
Warning: Only restore Stock recovery after nandroid Restore done..with same firmware
Tested on my P7300 and works..
Hello All
Thanks a lot for your help.
I'm now on overcome 2.2.0 with Motley Kernel.
I just done a Nandroid Backup before. I also found on Net a file to restore all, Stock rom & Kernel.
Thanks again.
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.
