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 .

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 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.
Hello!
Today, i decided to install cyanogemmod on my 2x. So i downloaded ROM manager and downloaded cyanogenmod. everything went fine until i was going to boot for the first time. I got into a bootloop. so i tried taking out the battery and all that stuff but it still would't work. So i tried to recover the phone. I recovered it to a month old backup (I could not find the one i made in ROM manager before i installed cyanogenmod) The recovery went fine. But, when i rebooted it got into a loop on the lg logo! (the one without the loading bar) it would just load the lg logo, be there for like 10sec, then it would do the same. I tried recovering one more time, but it didn't work. The same thing happend. What should i do? :S Should i wipe data/factory reset?
EDIT: My phone was on android 2.3.4 before i download cyanogenmod.
BTW before i installed cyanogenmod, i forgot to clear cache and data. I was in a hurry so i did't notice the screen popping up, I automatically pressed "ok" without selecting anything.
Thanks for the help

Different partitions... Look for something called backtoext3 in the dev section (or somewhere else) The problem is that when you flash a custom rom like CM you convert your filesystem to EXT4, while stock is EXT3.
So basically what you have to do is:
1) Reboot into recovery
2) Wipe everything
3) Flash Backtoext3 zip
4) Restore Nandroid.
This should work. this will take you back to stock.
So i have to restart the phone, Choose wipe data/factory reset, then flash backtoext3 (how do i do it? lol) then restore nandroid (the backup i just tried to restore twice?)

Yes
Flashing backtoext3 is just flashing the zip file you put on the sd card. (and then install zip from SD ) an then restore your nandroid stock backup and you're back on stock.
But you said you wanted to try CM right? In that case, wipe everything (factory reset/data + cache + dalvik) and then flash the CM7 rom and you have CM! Don't worry about backtoext3, your partitions are already on EXT4, because of your prior CM flash.
Ohh! Thanks Can you send the files for cm (2.3.4)? I've found some, but im not sure if my phone is compitable with them :S im really afraid to mess something up again
My. Signature. (CM7 temasek's KANG = the best CM7 at the moment )
I did everything and i got into a bootloop at the skating andriod screen again
OK, restored my phone back... Now it wont connect to the network and the battery has a question mark inside it. It also says the battery level is 999% heelp
Nvm, got my phone back to normal still dont understand why cm wont work...
You need cwm5 to flash cm.
I have a G2x, which is basically the same phone. But anyway, I would recommend nvflashing CWM and not getting it from ROM Manager.
CWM 5.0.2.0 will do just fine, but it is indeed old...
Anyway, are you sure you waited long enough on the CM boot screen? The first boot might take a couple of minutes. (4 or 5)
So, I installed the GingerDX on my X8
It booted successfully
I rebooted my device, and started the CWM
I restored my data from CWM (backup and restore > advanced restore > restore data)
Then when I reboot, it froze at the bootanimation (after the SE logo)
And I have waited it for like 15 min
But still nothing happened
If I do full wipe, it will still work (I've tried already)
But I won't get back my data
SO, is there any way to get back my data from CWM and put it to the GingerDX ....?
The previous backup that you made using cwm was of gingerdx or it was some other rom..
If it was of the other rom then thats the problem.

maybe you restore in different kernel
ie : you're on B kernel, but you restore some backup from A kernel..
and you'll get stuck or md5 sum error..
when I got that prob, I just flash my X8 on A kernel and restore it
then flash the new kernel (B) and backup!
then factory reset, etc
Flash ROM
Well the exact same thing happened to me! What I did was boot into recovery , make a system backup, then install your kernel again then rom, then wipe dalvik cache. After that boot. Then after you have set everything up go back to recovery and advance restore only the data from when you couldn't boot, then boot again, I hope this helps!
You have to make a fresh start,that is the only way.eclair backed data doesnt like 2.2+

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.
