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!

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] Nandroid backup not restoring

So i exchanged my phone out today but I kept a backup of the nandroid backup on my computer. After placing it back on the phone it says "error restoring /system", then stops. I have two other older images and they both say "error restoring /data" and stop. Anyone know how I can fix this?
I am wiping data/cache/dalvik before performing this
EDIT: now it seems I cant get my phone to boot up anymore. It just get's stuck on the galaxy note II screen. This was done with a brand new phone.

Resetting counter without Triangle away

Hello guys, I'm a user of Moon ROM and when I tried to upgrade to v10 .. It was upgraded successfully .. through AROMA installation I backed up EFS, It was backed up into a folder .. not a tar or IMG file, And I found out that I lost my IMEI, and I couldn't find out how to restore the " folder " EFS backup .. So I tried various ways, In the end I tried to make an IMG file of that folder by ImgBurn and then restored it using this script
I got into a FOREVER boot loop, I tried to unroot, i tried to go back to stock firmware, I tried to reflash v9 Moon ROM and v10 again, I tried everything .. Also getting failed to mount /efs in recovery.
It's just killing me and I actually lost hope
So I was wondering if there's a way to reset my counter so I can send it to warranty.
Since I can't boot up to use Triangle away, Any solution ?

Sorry, but, you pretty much screwed your EFS partition by doing serious mistakes.
First of all, that script is backing up/restoring as RAW image that is taken by DD
I never tried to backup EFS using TWRP. But probably it's taking the file(s) in /EFS partition, not taking a RAW image.
So you tried to create a raw image from TWRP's EFS files using ImgBurn and restored it using DD (that script does that). Big mistake.
All you had to do was restoring EFS back using TWRP
However I think you can still restore EFS if you still have the EFS backup taken by TWRP?
If yes
Find a EFS raw image of Note 2 from somewhere (from a friend or internet...)
It has to be taken by DD (script also will work)
Then restore it using that script
Then enter into TWRP and restore your EFS which you took using TWRP before.

Thanks in advance, So let me get this straight .. I have to look for a EFS img backup from a friend or from internet and restore it then restore the folder backup that I took using AROMA ?
should he be using the same ROM/baseband/kernel/etc or even from my country ?

As long as the device model matches like n7100, it should work. It doesn't has to be same ROM/baseband/kernel.

Your EFS partition corrupted because of your writing improper image.
That's why you can't get your EFS partition mounted.
You still need a raw image of EFS partition of Note 2, then restore your EFS backup properly.

Ok a guy was nice enough and gave me his IMG backup ..
Now I'm stuck at how to restore it !
I mean I can't use the script because it needs the phone to be booted up and android debugging on.

Don't do anything. I'm going to make CWM update zip for you. I'm a bit busy right now.

Put your efs.img file into the root folder of the zip file
Then flash it via CWM or TWRP
Then restore you original EFS files

Installed new ROM without gapps

Hello! I am posting this because i'm new to this rooting/custom roms thing. OK. So i have a Galaxy Note 2 GT-N7100. I rooted it using odin, then tried to install new rom. Downloaded CWM, booted into recovery mode and installed new rom. After this, i accidentally pressed 'Reboot' instead of installing gapps & wiping cache and that stuff. Now, my phone starts with the new rom, but i can't get back into recovery mode to start over. When i press vol-, home and power button, after pressing vol+ it goes into download mode (i can't do anything here). Any help will be appreciated!
UPDATE! I tried to flash odin recovery, and now my phone is stuck at the bootscreen. The only thing i can do is get into download mode. PLEASE HELP!

I've managed to get rid of the problem above by installing original firmware from samsung (android 4.3) and worked. The problem is, after that, i installed X-note rom (v2.1) and i think my imei is corrupted now. When i installed x-note, it asked me if i want to make an efs backup, and i accepted. If this is the problem, does anyone know how to restore the backup made? I found it on phone memory (i know it exists) but when i go into recovery mode in cm and i click restore from /sdcard nothing happens (no files to restore). Can someone tell me how could i restore the efs backup?
P.S. I checked phone's IMEI and it starts with 0049.

Alright so what is the back up extension ? Is it efs.IMG? Is it 20 KB ?
Please note that restoring efs backup has nothing to do with CWM recovery, its a program you download on PC that backs up and restores your device.
With regards,

Hi! My efs file is .tar and it is <1kb, somewhere around 20 bytes. When i open it, it doesn't show any items in the archive.

Stuck on Google logo after a Nandroid backup, nothing works (FIXED, TWRP+EFS issue)

I was doing normal stuff when I noticed that for some reason my google account had dissapeared from the device. It is not the first time that happens not only in my N5X, but also on an old S2 so since I'm paranoid instead of just putting it again, though of some malware and decided to restore a nandroid backup I did few days ago after reflashing august v6.0.1.
I was using @jollaman999 's multirom and it's recovery, and the recovery gave some strange errors (got an screenshot but on the device..), after reboot I was stuck on Google logo, after that, the bootanimation dots appear but they dont move, and the device resets.
I tested entering bootloader then recovery, and the original TWRP 3.0.2-1 from the backup had recovered and was working, so I decided to restore the very same backup from there. Checked md5s and all good (only a warning about a ' ' or something but all the md5s were good, it asked me to disable the md5 checking option). Restored everything without a single problem, wiped caches and rebooted.. in the very same situation.
I decided to just sideload the last full OTA from August security patches, and I sideloaded it normally. After sideload, not only the problem persisted, but also the original image that appears when turning on the phone (the warning about unlocked bootloader, which usually is orange) was red and talked about corrupted phone. I just flashed TWRP with fastboot and flashed ElementalX kernel and the turn-on screen turned to be orange ok (wtf?), but nothing got fixed and I was in the very same situation.
I decided to do a complete wipe after saving the data on TWRP, including formatting system, and then sideloaded the full OTA again, again without errors, but I appear in the same Bootanimation start-bootlop status than before.
So I have access to aboot (fastboot) and can flash TWRP and use it, but something is wrong and I am kinda lost, never been on this situation. What would you do guys? The OTA supposedly flashed Bootloader, Radio, Boot, System and Vendor and checked that everything flashed OK, yet the boot animation doesn't even start moving...
The Nandroid restore image doesn't have MultiRom.
Thanks for the help guys.

Edit: fixed, see lower post for details.

I'm stuck with the same issue. I suspect the power button, seems like a lot of users have problems with that.
I opened my phone and took a look, but the button seems fine..

Okay, issue fixed.
The problem was the EFS partition. When I restored the backup, it included entire backup (EFS) and for some reason EFS backup on that nandroid does not work, and kills my phone..
I tested restoring everything but EFS from that backup, and then EFS from an old copy... and SUCCESS.
I didn't think EFS could literally kill the phone, but apparently it does.
Also TWRP has some nice bugs, if you restore an entire nandroid backup, it says OK including EFS (but after reboot its stuck). If you restore only EFS, it FAILS (cause /efs2 is not found or something like that.)
@Dees_Troy this happened with both TWRP 3.0.2-0 and 3.0.2-1, I had a nandroid backup where restoring everything (including EFS) gave a success but killed the phone, while trying to restore only EFS gave something like (/efs2 not found) and made the phone not boot. In a rage impulse I deleted that backup -.-, I shouldn't probably if you needed some data, but I was so damn nervous, sorry.

Not needed, apparently it was all EFS problem, not any other partition, so either stock or custom roms were ****ed and nothing did boot. Thanks a lot for the help tho!! :good::good::good::good:

If it was the problem button, you couldn't be on aboot (fastboot) or recovery and do stuff .
In my case it was all TWRP+EFS problem.

If you aren't in my case (didn't try to restore also EFS.. dunno why but last time), your problem isn't probably EFS.
Anyway, don't you have an old backup of EFS? It's the first thing I do when getting a phone, boot TWRP, backup EFS, then backup the rest and save those like gold.

Send it to Google for repairs lol.. (it's a Nexus, a lot of people have sent it unlocked and everything and Google covers it, it's a dev device after all).
Also, thereis a thread from bitdomo in this subforum to flash the N5X with stock LG software, that fixes bootloader problems but not sure EFS, try asking him if he could solve your problem?

I have a backup of my EFS that I made with TWRP, but my bootloader is now locked and I've flashed the LG TOT. I've been trying to fix this phone for days. It's stuck bootlooping at the Google logo/4 colored dots animation.
Is there any way for me to restore my EFS partition? Or am I screwed?

It names it after the day and time you did the backup, but the files are named efs1.emmc.win/.md5 (at least on my mac)
