Why do I keep getting bootloops when I restore nandroid backups ? - Galaxy S III Q&A, Help & Troubleshooting

A week ago,I flashed cwm touch recovery(1st time I install a custom recovery on my gs3) with odin.I decided to try out wanamlite so I made a nandroid backup of my ROM(stock 4.1.2) then flashed wanamlite.I had a titanium backup of my data so I could restore it on wanamlite but I forgot to put it on my pc before flashing and wiping data(silly I know lol) so I wanted to restore my nandroid backup so I could make another TB of my data but the restore wasn't successful.I got this error message in cwm touch ''error restoring /data !'' or smthin similar and I got in a bootloop.I tried flashing back stock ROM and wiping data(with sd card) then tried to restore the nandroid again,got the same error.I later found out that titanium backup can restore data from a nandroid.Anyways,I tried to make a backup using TWRP but when I tried to restore it,I got in a bootloop again...what could be the problem ? I never had this problem with my gs2...
TL;DR:restoring a nandroid backup gets me in a bootloop whether I use cwm touch or TWRP.

are you backing up to the internal?
have your tried backing up multiple times?

Yes I backed up to the internal sd card.I backed up once with cwm and TWRP.Btw,when I tried restoring I had to move the backup from pc to phone because I did a full data wipe and the backup was gone(in both times) if that makes any difference.I have made sure the backup was the same size when I moved it to and from my pc.

Did you enable MD5 check? Could it be files damage to cause unsuccessful boot up?

No but why would they be damaged ? and why would it happen TWICE ? anyways,I will try again now with md5 check.
UPDATE:tried out with md5 checking,didn't get any errors but I still got into bootloop :/

if you didn't turn md5 on Before backing up, there's no md5 to compare to, hence no errors.

You haven't screwed up your phone but you have lost your data if you haven't done a nandroid... Why do you format your SD BTW? It is not necessary unless you have Apps2SD... Also a nandroid doesen't save your SD card data it saves your custom ROM with all your mods to your SD... Your text is actually quite confusing... Have you lost your modified ROM or your SD card data? If it's your SD card data you might be able to find software on the internet for recovery of lost files...
just download a new rom;
go into recovery;
check 'usb toggle mode';
copy *.zip to your phone;
wipe all the things you need to wipe;
flash your *.zip
*after you've created a new BART or Nandroid backup of your working system,
copy the BART or Nandroid folder from your SD-card to your local pc so you always have a good backup by hand
**you have NOT bricked your phone so don't stress out

[Q] Nandroid question

Will using the nandroid backup also act as an odin? Restoring and deleting everything? Basically will it delete everything on the phone and restore it to my backup as if i was using odin to do it?

From what ive seen it takes the phone back to the same state it was when you made the nandroid

This is true. Think of it similar as Windows system restore feature. Remember that all data on your internal "sd card" and external sd card stay the same.

MD5 Sum mismatch

I was on AOKPCB and flashed neutrino.. before that I made a backup pf my apps through titanium and a nandroid backup before flashing.. unfortunately I was not able to restore apps and data from titanium.. especially whatsapp messages. So I sayd let's restore AOKCP, but unfortunately the MD5 Sum check fails somehow.. Does anybody know a workaround?
Use TWRP2 recovery instead of CWM or romracer. You won't have any problems switching Nandroids back and forth. I don't think it will restore previously corrupted backups, but it's worth the shot.

I also had this same problem and I copied the backups off my sd card to pc, formatted the card and put the backup back on and it then worked!

Unable to restore Nandroid backup

my s3 is unable to restore nandroid backup until restoring data proses.
it will give error restoring data thus stop the proses.
already tried backup in internal & external memory but still fails.
my cwm version is 5.5.0.4 cf-v1.5
need advice & help.
i dont have problem with my s2.
thanks.
What a coincidence. I was going to send similar post . Yesterday I experienced the same problem. I wanted to go back to ICS from JB but CWM failed to restore data. Fortunately I had titanium backup as well, so I could restore all my applications.
The error message was "Error while restoring /data!". I have recovery.log if someone wants to look at it.
Use the same CF Root version and CWM to restore that was used to backup sometimes helps .

I used the same version for backup and restore.
Maybe you should try touch recover 6.0.1.2
It work fine for me
Can I restore my old backups with touch recover?
Try using advanced restore and reinstall the components separately

Yes backward compatibility.
Ok. Will try it in future. Already recovered all my data from titanium backup.
never had this problem myself, have you checked the size of the backups, if they are less than 700 meg the backup process may not have worked, was there enough space on your're SD card to do the backup in the first place?.
Try copying the backup to the other SD card, does it copy ok, if so try to restore from there. Seems to be there has to be a reason for this that you should try to get the bottom of.
My backup was around 3.5GB. There was over 9GB free space on sdcard and 5GB free on extsdcard. Don't think there was not enough space.
i have backup & restored in internal & external memory yet the restoration of data still failed.
in addition i have tried restoring nandroid by "advance restore from internal sdcard" step by step & still failed when restoring data.
noted that i have used the same version on cwm with my nandroid.
hope someone able to give me a solution for my problem.
i never have this problem with my S2.
Problem solved!
I have manage to successfully restored my nandroid backup by flashing cwm touch recovery 6.0.1.2 from this thread click here.
:victory:
Same problem as kakiboyer, except a bit funkier.
got the 64GB microSD card off amazon popped it in and it just just went. no formatting no nothing.
backed up my original stock image using cwm5.5 and saved it onto the external SD card.
then flashed supernexus build 5 which gave a problem with my external 64GB SD card when i turned it on,it said it was damaged and needed a reformat (not fat32 im guessing) either way the flash was fine, i just need to reclaim the stuff on my 64GB SD card.
I then tried restoring to my original image and then removing the data that way, but instead i got the /data error (hence why i'm here).
Same set up as kakiboyer by the way.
using cwm version 5.5.0.4 cf-v1.5
so when i updated to cmw touch 6.0 it now can't see the external sd card (only the internal one).
BUT when i flash back to 5.5 it can see the external SD as well as the original backups, all my music/movie files etc. on the external SD.
So since the OS can't see the card, touch 6.0 can't see it and i can't revert back to the original image; how can i get my stuff off this SD card?
Fixed it!
Slapped the sd card into my windows machine and ran "chkdsk F: /r" with F: been whatever the sd card is!
got everything back, it was extFAT so copied everything off, reformatted to fat32 and put everything back on.
Happy days!

Data lost after a nandroid backup restoration

Hi there. Yesterday, before flashing leaked 4.2.1 ROM, I did a nandroid backup to my external microSD card using Philz Touch Recovery v. 4.63. The process of backing up was successful.
The problem came when I restored the backup. (Before restoration, I had to reinstall the PhilZ Touch recovery and, from it, I did format cache, format system and format data). I recovered my XXEMA2 ROM with all the apps and configurations I had before, BUT there is no trace of the pictures I had in the internal memory or the files I downloaded.
I tried to repeat the process, but I got the same result.
Does anybody know a solution for this?
Thanks in advance.

Nandroid only backs up your ROM, recovery, apps, app data, etc. and not the data stored in your internal storage.

Ooopppps, I thought it makes a complete image of the phone! (for example, on many websites it's compared with Norton Ghost for PC). Good to know for the next time...
Thank you for the information, Oomahey!

After going back from 4.2.1 to 4.1.2 you'll have your whole Internal Memory in a folder "0". Find it on your Internal Memory. All your data and files should be there. Just transfer them from folder 0 to root of Internal Memory and all will be like before flashing 4.2.1

I seem to be blind! I was looking for the "thanks" button, but I didn't found it (I thought that maybe it didn't appear since I was surfing from my mobile). That's why I said "thanks" texting.
EDIT: I was not blind. In the default version of the forum (the classic one) that appears on my Opera Mobile there is not "thanks" button. You need to change manually the versiĆ³n to 2010 one or higher.

I do have the "0" folder with the old (sub)folders, but all of them are empty :crying:
Maybe it was not a good idea to do format cache/system/data before restoring the nandroid backup... As I thought all data were preserved in the backup, I prefered to delete any trace of 4.2.1 ROM .

Well, that might be the problem. I had also restoring 4.1.2 backup after trying 4.2.1 FW but I didn't do wiping or formating - I just restored backup and there was that 0 folder and all files from Internal were there.
