On my Galaxy S5 (SM-G900F, Android 4.4.2) I made a nandroid backup of "everything" (boot, cache, recovery, system, etc.) about six weeks ago (using PhilzTouch recovery). Yesterday I tried to restore it, and it seemed to work but when Android had booted up I started getting force closes all over the place.
I tried wiping cache and data, but it didn't make any difference. I had a look at the log for one app when it crashed, and it was due to java.io.IOException: open failed: EACCES (Permission denied). I have not changed anything on the SD card since I did the backup (sent the phone in to repair a dead pixel but they wouldn't do it on warranty, so I got the phone back the way it was).
One idea I had was that something was messed up with the file permissions, so I tried the app "Fix permissions" but that didn't help either.
I then thought I'd try to flash Lollipop using FlashFire. Everything went well, and I was really surprised to see that now all the apps were working flawlessly! So to get back to KitKat (which is what I want), I then tried flashing the KitKat ROM (BTW, these are all official samsung ROMs from SamMobile. Now it didn't even boot properly, it got stuck on "Android is upgrading - Starting apps...". Tried wiping data/cache again but nothing worked.
I have since tried repeating the but without flashing Lollipop (i.e. flashing the same ROM as the one in the nandroid backup when running the restored KitKat installation), but it always gets stuck on the "Android is upgrading" screen (have tried many combinations of boot/preload/system/etc).
So it seems that I CAN restore the KitKat nandroid backup, but it's unusable "as is" because of most the apps force closing. However, if I flash Lollipop "on top" of the backup, everything works.
Can someone explain this, and possibly provide a solution? I'd really like to have this phone exactly as it was when I did the nandroid backup.

I have tried several different Rom Managers without a problem on my G Tablet. Have been using TNT lite. Recently I switched to Vegan Gingerbread edition, but when I went to backup my old Rom (TNT Lite) the backup hangs on backing up the cache. I tried wiping the cache and formatting the cache, but it always hangs indefinitely.
I installed Vegan Gingerbread anyway and it appears to work perfectly, yet I still cannot backup the rom with Clockworkmod (always hangs on the cache). If I try to look at the cache partition in filemanager, it shows empty, though I am not sure it is actually recognized. I can't seem to do anything with the cache at all.
I am, by no means an expert, but have had no problems with this before. Backup did work before the recent problem.
Since everything is working with my G Tablet now, I am not sure there is an actual problem with the cache, except that I can't backup the Rom without it hanging on the cache. This may limit my ability to load other Roms in the future.
Please help.
I have the exact same problem. I've had no issues backing up and restoring ROMs myself, but now I'm having issues with my tablet not being able to format or restore cache. I can install a ROM, but it takes a long time to actually load up - it can sit on the first splash screen for easily 5 minutes before it boots into the ROM, wher as before it took around 1 minute or less. Are you having this slow boot problem as well, or are your problems strictly with the cache? I'm going to continue to look into it (currently looking into using nvflash to do a restore and see if that irons things out), so I'll let you know if I come across any solutions. And please, let me know if you do as well.
hey guys i had the exact same problem before but nvflash fix what ever the problem was and the newly installed cwm work as it should. are you getting "ANDROID" screen right before it goes into cwm?
I am not getting the Android screen before ClockworkMod, but I generally boot with the power/vol + combo. I also have not changed Rom's recently, so I am not sure if this would be a problem or not. I do not have any boot problems that I am aware of, nor can I see and performance problems resulting from my inability to format the cache. The only problem is I can't wipe the cache, backup the rom, or format the cache as it stops on formatting cache partition and therefore can't continue the backup process. Other than incomplete backups I am not sure what problems this actually causes. Do you know.
I haven't used NVFlash yet, but I guess I will have to give it a try. Am I simply restoring the ROM to factory state and starting over or is there some other process I am looking for? Unfortunately, I did not get a proper backup of my original factory rom, so I will have to rely on downloads. Any tips on NVFlash would be greatly appreciated.
It's Fixed! Thanks for the tips.
Here is how I did it:
Ran NVFLASH - it was much easier that expected. It fully restored the original stock Rom, but I still had trouble with clockworkmod. Mostly it would not boot into recover mode. I then re-rooted the tablet using the Update.zip method, Then everything worked fine including backup and cache format.
I continued to restore my tablet and tried the backup each step of they way.
I installed Vegan Gingerbread - Worked flawlessly
I reinstalled MyBackupsPro and all my apps and Data - Also, worked flawlessly
I reinstalled Rom Manager - also worked flawlessly.
I used Rom Manager to upgrade ClockworkMod to 2.5.1.8 - then the backup/ format cache problem reappeared.
I then ran Rom Manager again and selected flash alternate ClockworkMod. It restored version 2.5.1.1. Then the backup and format cache worked again.
It appears that my Gtab does not work properly with Clockworkmod ver 2.5.1.8 and that was the entire problem.
Since Version 2.5.1.1 works great, I see no reason to upgrade this again and consider my problem fixed. I hope this info helps others
The device is the LG LU6200 (gfs)
device was rooted and on LU6200_162_CN_Yang_0704 ROM. '(ICS)
Today, the gf was prompted to update/upgrade system by LG and she chose to do so after feeling harassed by the update notices. now the devices goes directly into CWM after booting from LG screen (it won't load normally). She tried restoring from zip, but it has no effect; it reboots into CWM after the bootup page. We restore using every backup file available, tried wiping cache, data, and dalvik, then restoring, tried going into advanced restore and restoring boot (presumably the boot.img), tried re-installing the ROM, but to no avail.
I'm guessin the official update clashed with the bootloader...?
also worth mentioning, before installing CWM, Power+Vol up usually brought up the restore factory screen. Afterwards, it went into CWM.
I'm planning on re-flashing v142 .kdz with the upgrading tool on Sunday since I don't see her until then, but could use any advice/suggestions in the meanwhile.
thanks!
I've done everything: cleared all data, tried to restore backups, do a full charge, nothing's working.
I upgraded to 4.4.4 Liquidsmooth, but I decided to restore (with clockworkmod) back to 4.3.
I got the infamous MD5 Mismatch error, so I recreated the nandroid.md5 file, and I successfully booted back into 4.3.
Now 4.3 kept giving me errors so I turned it off and tried to restore BACK to a backup I had once I upgraded to 4.4.4, and nothing happened.
Now I'm in limbo: the phone crashes on the boot screen, and if i restore either the 4.3 or 4.4.4 backup, clockworkmod just crashes while restoring.
At this point I'd be fine with deleting EVERYTHING and starting with a fresh phone, but I don't even know how to do that...
Help would be MUCH appreciated, thanks.
Follow the guide in general forum sticky on how to wipe and flash a stick firmware with Odin. Make sure you factory reset after flashing.
Alright, I know enough to be dangerous. I rooted my Samsung tab a 10.1 by installing twrp and then super su, all went fine. I then began to try and make a nandroid back up. It kept saying unable to mouth data, so I read a little and I changed data format. This caused a boot loop. Went in and changed back data format and used twrp to reset. All was fine again. I then attempted to use titanium backup. I recited a message backup was successful and reboot. I rebooted and now a boot loop. I then tried to reset with twrp and my file is gone. So, I downloaded what I thought was the right firmware to flash with Odin but just made that worse. Does anyone have a download for a rom I can flash with Odin to get this thing going. I have downloaded a couple and the either don't work or are the wrong one. SM-T580.

Alright, I was using an olsee version of odin, got the new one and I was able to flash a rom. It says tab a 6 on boot up bit it is functional. Now my question? Can anyone recommend a custom rom that is nebiew friendly. I'm food at following directions and problem solving but I about had a panic attack, I just got this $300 thing. Sigh off relief for at least getting it functional again.
Hmm
Ok so I have flashed a stock rom, 6.0.1, flashed TWRP, and installed SuperSU. all is working well again. However I am still getting "unable to mount data" message in TWRP when i try to make a backup. If i uncheck data on the list it backs up fine. This is what got me in that boot loop pickle before when i tried to change the data format. What data format? Idk, im scared to jack with it anymore, and im done with titanium backup, it has burned me in the past, though i think what went wrong there was when i backed everything up i then went and change data format and after all that restored and the backup was in a different data format. Idk newbie guess. I am just trying to getting a reliable nandroid backup. Anymore ideas? Perhaps i should just leave it alone and be happy with just having root.
So I created a full backup of my device using TWRP and now just tried to restore it and it's just completely messed up my device. I got an error saying extracttarfork() process ended with error=255. My device was a custom timurs rom which I dont remember how to go through the whole process again. From the videos I have seen apparently I need to reflash it. How do I do that? What files do I need? Can someone please help
So, although the message logs shows that it formatted and wiped the system, I just thought i would give it a restart and see if I get a bootloop. But it seems to have not done anything of such like deleting or wiping because the system is still the same. However, I did notice my bootanimation logo has gone back to the version before the backup. So I don't know what exactly has happened.
Is it possible on TWRP to do a clean fresh install and then flash the Timurs Kernel rom back on? My tablet is in fix mode and I don't really have access to the volume buttons to force TWRP easily. So I'm thinking I would like to do a clean android refresh and flash the kernel again.
It's definately messed something up because now when I try to transfer a file into the System partition using TWRP i get error saying Full SELinux support is present. This never happened before. Any ideas please on how I can just start fresh on this?
