HELP NEEDED with CWM "error while restoring /data!"

Hey guys,
I have kind of a serious issue right now. I used Touch Recovery 5.8.0.2 and made a full backup today of my whole ROM (2.5GB) before trying out some mods which eventually didn't work. So I decided to wipe and restore the backup I made. No matter what I do I cannot get it to restore my data partition properly. I keep getting "Error while restoring /data!" message, however it does the boot image and system fine but doesn't continue to cache and sd-ext because of the failed data. Whenever I boot it up, some of my apps are missing from the home screen and practically all of them are not working when I launch them (force close). I also get boot up error of Google+ force close, among a bunch of other issues. This is happening even when I try to restore an older backup as well. My device is not working state right now and although I can just restore the stock images to get it working again, it is urgent that I restore my data ASAP! I tried wiping several times and even using the non-touch 5.5.0.4 recovery to restore and same thing keeps happening.
Any help would be highly appreciated!
Please don't tell me my backup is corrupt
Update 1: Eventually I gave up and started from scratch but I have confirmed already this happened on a fresh backup as well, at this time we are trying to figure out what is causing this so I can go back to safely backing up and restoring backups.
Update 2: We have test builds of TWRP Recovery that may have resolved this issue! We need testers!
Please see this post: Link Here
Update 3: We have test builds of ClockworkMod Recovery 6 that may have resolved this issue as well! We need testers!
Please see this post: Link Here
***Always see last few posts on the thread for updates on what we discovered just in case I don't update the OP***

Unfortunately I also have the same error today!
Please help us out.

is your phone encrypted?
are you running stock recovery?
are you running a stock Rom?
have you done a factory reset yet?

Hi Spectre85,
My phone did fine yesterday, I was running AOPK Milestone 3 with FAUX123 kernel.
But when I woke up, my phone looked like it's battery was emtpy.
- When I plugged the phone with the charger, I started the phone again.
- Unfortunately my phone keep looping at the Google screen over and over.
So I pulled the battery and put the battery back again in the phone.
- I went to the bootloader and went to CWM recovery.
Deleted Data, Cache and Dalvike cache.
- Tried to retrieve my backup rom, but keep getting this "Error while restoring /data!" message.
I've tried to install other roms as well, but I still keep getting the bootloop at the Google screen.
Have you guys have any advice for me?

For me, no, no (CWM Touch 5.8.0.2), yes (stock rooted 4.0.4), no but my goal is to restore my data not erase it.

I had this happen to me before, what I did was flash a factory image through fast boot and it was fine after.

Thanks guys..I flashed the factory image through Fastboot mode and the phone works perfectly again! Too bad I lost all my data, but I'm happier that I have my phone fully functional again

You can't access your backup right? There's no way you can copy the file to your desktop?

I did copy it. I have full access to the file. Also, just fyi my goal here is not just to get to working state (I'm aware of the stock images) but to actually recover my data. My phone is currently on stock images completely blank and working now.

Fast boot flash the nand images just like u did the stock ones.

Nanadroid files can be flashed in fastboot? Are you sure? First time I'm hearing this. Doesn't fastboot need .img files? These are .tar files.

Open it up and see if its image...sorry all my recoveries use images.

I guess it depends on the recovery version you use. I remember older versions actually had .img files. However 5.5.0.4 and Touch 5.8.0.2 both have ext4.tar files.
Which version of recovery do you use?

If you have root, you can restore your data partition using Titanium Backup. Use "Export from Nandroid Backup" within TB, select the nandroid backup and then select all apps that you want to restore

Yes. Titanium Backup can restore all your system apps as well as downloaded apps from a nandroid backup. Not as clean as a nandroid restore from CWM but essentially the same thing. But try to see if Titanium Backup can extract your nandroid backup. It all depends on what exactly went wrong with your nandroid backup to begin with. I don't think it restores cache. So not sure about wallpaper.

You're right. This works great for restore data to select apps (got my notes and game saves back). I think the icon layout is held in the launcher settings, I'm about to try and restore the data to the launcher app and see what happens. I'm making a CWM backup of first of my current state (that's assuming this backup will actually work).
EDIT: Yes! That did it! Widgets position weren't saved but it's ok I only had a few so I manually put them back. Thank you! I never knew TB had the ability to work with nandroid backups.

I guess this now just leaves me figuring out what went wrong with the CWM backup. It happened twice (I have two backups from the same day that won't restore). Does anyone else use CWM Touch 5.8.0.2 and have successful backups? I would experiment to see if it works now but I don't want to end up with a corrupt backup and redo everything again.

Yes with me its the same thing my data its corrupt is even worse every time I do a nanobackup and restarted my phone the phone freezes on the boot logo and I have to go back to recovery trying to use my backups but I can't so I have to flash a new from again and start from the beginning again!!!! Anybody here has the same experience with that ???

So AGAIN, I'm having the same issue. This time on a recovery 5.5.0.4 that used to work for me when I originally got my phone. I think either my data partition might be too big or something but this really needs to fixed pronto. Anyone know how to contact Koush directly in regards to this matter?

[Q] Anyone else having Nandroid restore problems?

HTC One V [CDMA], Virgin Mobile US, original (pre-OTA) radio version, TWRP recovery
Has anyone else experienced flakiness with Nandroid backups on this phone? All of them that I've done with major OS changes—even after factory reset—have failed to produce a working restore even though they were taken from a working state.
I'm also unable to get back my previously-working CM 10.1 ROM even though I followed the exact same procedures (with the same files) that I used to get it working before.
This has been happening since my first failed Nandroid restore trying to go back from CM 10.1 to the HTC Sense Nandroid backup I made before attempting CM 10.1 in the first place. I thought this was due to the Sense Nandroid having been made under the OTA-upgraded radio version (I had to use the stock rom.zip from the RUU to get CM 10.1 working at all), but now I'm not so sure. I get the HTC logo and angry red legal text indefinitely now with those setups.
I can't even get back to the Nandroid I made of the stock HTC Sense ROM right after I restored from the RUU's rom.zip.
Anyone have any idea what I'm doing wrong? Or is this model really just that much of a pain?

Are you flashing the correct kernel in fastboot after completing the restore? The recovery is not able to flash a kernel, that still needs to be done through fastboot, even with a nandroid restore.

That's the boot.img, right? I did try flashing that after the restore didn't work the first time. No joy.
EDIT: Actually, that explains why some of my restores have failed, but not all of them.
EDIT 2: Mystery solved. I think. The Nandroid backup I took yesterday evening must be broken somehow. I noticed a few minutes ago that TWRP wasn't actually telling me that it finished restoring the backup—it was just taking me back to the home screen. I switched to CWM Recovery to grab a backup I took yesterday Morning, and that one worked.
So now I'm just left extremely disconcerted that I can't be certain my backups are reliable.

I originally thought this was just an isolated incident, but it seems to be recurring. Several of the Nandroid backups I've made more recently, both within TWRP Recovery and via the Online Nandroid Backup app, seem to produce this result. (Fortunately, I have a known good backup that I've been able to use reliably.)
Is there a way to validate a Nandroid backup other than trying to restore from it? I don't mean comparing a hash (which is what I find using Google), but rather making sure that the original, uncorrupted file is valid for use as a backup.
As a side note, every backup I've done with CWM Recovery has been reliable, so my fallback plan is to switch to CWM. I just find TWRP easier to navigate.

I've played with recovery files before (se my signature) when cwm wasn't working well.
Basicly if you want to know that the backup is correct, you can only compare the hash codes (nandroid.md5) which is practically useless, because hases are made only for the .img files, so the OS itself is not protected like this, which is somehow ok, because the files are compressed to a .tar file, which also means it has it's own validation algorithms itself. So you can validate it if you can decompress the file (don't ask that how it could be done under windows) without errors, it should be allright.
I personnaly can say only this: use CWM 6. i-don't-know-which version (which is online now). There is a possibility for cache not mounting, and of course a backup to not be full, but as you can see from my signature, it can be "bypassed" so the OS will be backed up, and because we don't have S-OFF, it doesn't really matters. All of my backups from CWM is working (have at least 10 gigs at the time, from stock to EV).

I always use android file verifier by scary Allen (free market download). It has saved me many times!

so as a conclusion, nandroid backup won't restore boot image? and the option in cwm advance restore>restore boot is useless? Me also always got stuck using nandroid restore

Confirmed that comparing file hashes isn't helpful for this purpose—I just downloaded scaryalienware's AFV as suggested and ran it against several of my Nandroid backups. It said all of them succeeded, including at least one of which I know will not restore successfully. However, of interest is the fact that it took about half as much time to scan the known "bad" one, and further analysis shows that it's about half the size of the others. I'll have to make some more backups via the various mechanisms to confirm that the size is an indicator; it may be simply that I had fewer apps installed when making those backups.
Too bad there isn't some kind of Nandroid Restore Simulator. But even if there was, this phone probably wouldn't have enough memory to use it. Checking Nandroid backups in a VM would be awesome though!

Does anybody have a Odin-able copy of SM-T800 LRX22G.T800XXU1BOE2?

Apparently, TWRP v2.8.6.2 compressed images to external SD cards are damaged, and it wiped my Recovery Mode and part of my previous Stock OS LRX22G.T800XXU1BOE2 installation.
I was able to Odin a Canadian copy of T800XXU1BOCC_T800XAC1BOC4_XAC, but it isn't working properly on my SM-T800.
Can somebody please point me to a US LRX22G.T800XXU1BOE2?
Thanks,

What do you mean the backup was damaged, what failed and which partition?
You can reflash recovery then just restore system. No need to do a full restore.

Unfortunately. @ashyx - I'm not sure exactly where now. The recovery failure was almost instant (within the first 5 to 10 steps), and I remember that the error occurred right after a progress comment about EXT4. I lost the capability to boot up, and I lost the capability to get into Recovery Mode. My only option was to stay stuck in Download Mode, and hope that my battery didn't die before I was able to get a Odin image re-installed.
It was nerve-wracking.
I wasn't sure if the tablet would be charging while in Download Mode, and there was no way (that I knew of) to get out of Download Mode. I thought there was a high probability that I was about to permanently lose my brand-new tablet.
I paid for a subscription to Sammobile to get an older image installed until someone was able to get me the more recent stock image.
I'm too nervous to try and restore the image again without need, but I will definitely do it if you want me to. I understand the urgency to make sure that TWRP makes good images 100% of the time, and I am reluctant to do anything future to my tablet if I can't make a reliable back-up.
¿GJ?

Maybe your backup somehow got corrupted.
Which partitions were you actually trying to restore? For future reference if you made a backup of recovery don't restore it. Only restore it if you want to revert to a different version.
Also don't worry about bricking your device. As long as you still get download mode you will always be able to recover. I soft brick my tablet on a daily basis lol.
The only thing you need to flash to get into a bootable state is recovery. From recovery you can usually solve most issues. Even if your battery had died you would have been able to charge it and then power it back on. Also the tablet does charge in recovery mode.
Twrp can be a funny so and so sometimes. You just get the one time when it doesn't t behave as you expect. 99% of the time though its pretty solid.
I always find its good practise to restore a backup immediately after making it to ensure its sound. You don't want to wait until its too late to find out its corrupt.

Thanks, @ashyx - Good advice on the partition recovery steps. Normally, I have automatically accepted the three defaults, and swiped. I will not do that anymore.
I have found TWRP to be very reliable in the past: If it's working fine, I always get a good backup. If it's failing on something, I always get a bad backup image, or always can't restore. I haven't had a random corruption yet. There was a problem I saw with TWRP and my Samsung GS3 a few years back where it would corrupt compressed archives, but uncompressed archives were fine. Maybe this is a replay on that problem.
I will backup my current CM12.1 image uncompressed, and then try just restoring my system & data partitions from the previous backup, and let you know what happens.

I can assure you compressed backups should work fine. I have done it countless times. Probably just a one off for whatever reason, could be a failing sd card. You may find the backup is fine and will be ok to restore. I wouldn't be afraid to try again. When a backup fails to restore you usually only get an error message not a sudden crash and reboot.
Try making a compressed test backup by just backing up the cache partition then restore.

Is this backup also encrypted. I have seen that error with encrypted backups in the official twrp. However this was fixed with an update pushed to the twrp repo which I have incorporated into the latest build.

No, it just shows Team Win Recovery Project v2.8.6.2. It doesn't show any Samsung model numbers (If that is what you are asking).
I installed it using your All-In-One Root/Recovery tool.

Thanks, @ashyx! I'll download the SM-T800 F2FS version right now.
BTW, I've been really interested in installing F2FS. One thing I have been worried about, though, is that once I go down the F2FS path, it may be easy to really mess things up. For example, if I update a ROM, I would always need to use a F2FS ROM, or I might lose all my data - is that right?

Normally you would only format the data and cache partition to f2fs. There isn't much point formatting system to f2fs.
Also f2fs requires a special kernel. Myself and Tkkg1994(Iron Rom) have been working together to get this working properly. Still testing.
We are almost there.
Once formatted to f2fs you would need to reformat back to ext4 and flash a kernel to return back to normal. You could then flash your backup.

Need help to unbrick my Nexus 5X

Hi! My first post here (and not a pleasant one).
I bricked my phone by trying to sideload the android 7 september ota update.
I had root and TWRP recovery installed and I thought it would be ok to sideload the update from TWRP thinking that will erase system and recovery. But what I faced was adb sideload to stop to about 30% on pc and the options to go back or reboot system on TWRP.
So being afraid of a brick I didn't reboot and I flashed a nandroid backup (didn't have a vendor backup). After it finished I rebooted system to find out that the phone goes up to 4 dots and reboots.
The next thing I did was to flash a factory image. I flashed both the september and august images by running flash-all.sh with success (no errors) but still the device is in bootloop.
The last thing I tried was this: http://forum.xda-developers.com/nexus-5x/help/fix-nougat-bricked-phones-n6-thread-t3449640
but made things worse and then I could reach up to Google logo. So I flashed back the factory image of Android N August and I can reach again the 4 dots.
The odd thing is that when I flash TWRP I see a supersu folder in /. Do you think it affects anything? But system, boot, cache, sdcard, recovery, vendor are formatted during flashing the factory images.
I have the 32gb model and unlocked bootloader.
This drives me crazy since it's a soft brick and I should be able to recover from this.
Any help will be much appreciated!
Thanks in advance!

Just press the volume down and power button at the same time. Should get you into TWRP and then transfer the file you want to install the ROM on and flash it. That should do it. Hopefully this helps.

If you have your userdata backed up, I suggest you flash everything including letting it factory reset your userdata.
Keep in mind your nandroid backups are on userdata, so move those off the phone first.
One other thing, when you restored nandroid backup, did you use TWRP 3.0.2-1 and did you restore EFS partition? There was a bug in TWRP where it would crash your phone because it overwrote an EFS partition with the contents of another EFS partition due to incorrect filenames.

Yes i used TWRP 3.0.2-1 to restore EFS. Was the bug to that version? Is there any way to fix it?
EDIT: I downloaded and installed twrp 3.0.2-2 and when I try to restore the efs it says "efs2 no such file or directory". The previous version of twrp doesn't semm to have backed up this partition. I only find efs1 in the backup folder. @sfhub can you plz help me? How am I going to find the second partition of efs. Can you plz provide me a backup?

There is some info about this over on the TWRP thread.
Essentially if you write all zeros into the efs partitions, the phone will recreate the data (if you instead of non-zero data, it will think things are corrupted)
I suggest you read very carefully erverything you can about recovering from the TWRP EFS bug. This post will get you started, but I suggest you read the original thread from the 6p forum that is referenced in this post. I haven't done this myself nor have I read that carefully so don't want to give you bad advice and make your situation worse.

Thank you very much! I'll read it first thing tomorrow and I'll let you know what happened.

@sfhub thank you so much!!!! That was it! The dd commands fixed my problem. I didn't know that the EFS partitions could be reconstructed by the system. I thought I was done. Thank you for indicating the TWRP bug. I was not aware of it. I couldn't understand what could have possibly went wrong since everything was flashed successfuly from the factory images.

Can you please share the exact command you used for nexus 5x as the link above is for nexus 6p.

They are the exact same commands as for 6P:
ADB shell dd if=/dev/zero of=/dev/block/platform/soc.0/f9824900.sdhci/by-name/modemst1 bs=16384
and
ADB shell dd if=/dev/zero of=/dev/block/platform/soc.0/f9824900.sdhci/by-name/modemst2 bs=16384

TWRP bootloop

Hello
I'm trying to install Resurrection Remix, but everytime the flashing is done (Rom an Gapps) the phone reboots into TWRP only. No Lenovo logo, zero, nada. I thought it was a problem with RR and tried Lineage OS just for kicks but the same thing happened.
I've done the dd if=/ command method which i used some time ago with my beloved nexus 4 and Cyanogenmod nightlies; worked like a charm back then, however this time the path doesn't seem to exist.
Glad i made a nandroid backup. My phone can be brought back as new, no loss there, but i want to try custom ROMs.
What could i possible do to fix this?
Regards

Do you mean you don't see the Lenovo bootlogo during boot? What do you use to make and restore the Nandroid backup? Does everything work well after restoring the Nandroid backup? Also, most importantly, what's the model name of the device you're using?

The phone never gets to the Lenovo Logo, goes directly into TWRP after Reboot or Power On. Everything works after restoring from TWRP 3.0.3.
Phone model is A6020I36, Hardare Version H201.
Thank you.

All right, time for a little bit of experimentation. Now, this could be dangerous, and I hope you know how to recover a bricked phone using QPST.
Does the Nandroid backup have a backup of the boot partition? If so, I'd like you to reproduce the issue; and when you get to the point of restoring the backup, restore everything but the boot partition. Let me know if you see the Lenovo bootlogo during the reboot sequence that follows.

I'll read everything about QPST first and then i'll proceed hopefully this weekend, i'll keep updating here.
Kind Regards

Turns out i just needed to downgrade TWRP from 3.0.3 to 3.0.2 and everything worked as it should have been from the start.
Thank you for your replies. Cheers!

Happened to me one day, Shreps TWRP it's bugged, it have two or three bugs related with F2FS and the bootloop, you always can flash the Russian TWRP for solving this

I dont get it, can u pls explain it bro

This happened to me when I installed AOKP. Remove the battery and boot again. It works for me and that is how I do it every time there is an update. First boot takes time so don't panic.
