Restoring STOCK (or other) BACKUP after CM

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)

[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.

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] CWM Recovery - restore from backup - only data?

Hi Guys.
I haven't worked much with CWM so far and couldn't find a proper answer in the threads here.
When I do a restore from a CWM backup I've not seen an option to choose just data or apps ... so I suppose the whole system including the rom and kernel will be restored. right?
As I'm happy to have CM 10.1 running after all finally, I'd just like to restore the data (SMS, etc.) from a CWM backup. Is there a possibility to do so?
Thanks for your help.
Cheers

I don't think you can do that. I used titanium backup pro to restore only the apps+setting to do that.

Ok, thanks. Should have thought about it before.... Sometimes fingers are faster than the brain.

You can do an advanced restore and just restore /data but it's not recommented to do this coming from stock and restoring on CM I guess...

Stock and CM use different bases, and therefore restoring data of Stock can bring over some incompatible data/apk's and this can and most likely will cause a bootloop, from reading i think i can establish the safest way when your changing Rom's is to full wipe and 'clean' install. However when going from nightly to nightly this is not needed, and some data can be restored between same android version Rom's, for example CM10.2 is 4.3.1, data may work on slimbean 4.3.1.
Hope this clears things up for you.

I would also suggest to do a clean install without data recovery. If you want your data you can use Titanium Backup for App data. For the other personal stuff you can make a backup to your PC..

CWM Recovery, URGENT REPLY!!
I faced this problem that my rom got stuck on boot image, so I had another custom rom zip in my sdcard, so to install that I had to format my phone, now I have that backup and I only want to restore system settings, apps, app data, my data(sms, call logs and stuff), I dont want to restore the system or anything else which will make it get stuck on boot image again, now which choices shall I choose in advanced restore to restore only these specified items?
Please reply urgently as I have to travel in a few days and I wont be able to do it over there.
Cheers

Big problems after nandroid restore!

So I flashed CM11 on my dads phone, first taking a backup of the rooted stock that was on there. Now when I restore the backup (after full wipe) It freezes and crashes all the time!. It seems as soon as I touch the phone it stops responding to my touch. However the phone still makes the bubble/water sounds when i hit menu key. Please, please help since this is my dads phone.

Samsung TW based roms stock some apps in the /preload partition so did you use Philz recovery to make nandroid backup and check include preload (located in restore and backup => misc nandroid settings )?
if not then your backup is incomplete and flashing stock rom via odin3 is the best way to revert back.

Ah, my backup doesn't include preload. If I reverted to stock via Odin, would I still be able to restore just data?

After flashing using Odin, rooting using Philz kernel to get cwm, you can do an advanced restore of just data. It might not restore 100% data but should restore enough.
PS. Preload is only used if you had JB earlier.

back to stock rom

I want to revert to stock rom (4.1.2) from cm10.1.3. I have a backup of stock rom but don't know the procedure of reverting. Does it requires flashing kernal also and if any risk is involved? plz suggest

Start to read the sticky tutorials how to install a stock rom, how to restore backups etc.
The only risk involved: errors as a result of laziness.
In short: backup your CM, restore the old from recovery. If that doesn't work install the kernel/recovery you used when generating the backup, reboot into recovery and try to restore again.

Just to add to what ThaiDai said, I dont remember if the 10.1 CM recovery uses preload and if it was removed in 10.2.. But when you boot into recovery and if you cant format the preload partition in mounts and storage, then flash any Philz kernel, reboot into recovery, enable preload in settings and restore the backup.
