Can't restore backup on Nexus 7 - Nexus 7 Q&A, Help & Troubleshooting

Hey all, I updated to a beta of Paranoid Android that screwed up everything. I created a backup ( and actually have several more older ones) with ClockworkMod Recovery. The very latest backup will not restore for whatever reason, but the main issue is that it's the only backup I can even see.
All the other backup folders don't even show up in recovery. Accessing /sdcard/ I can see them all. Any ideas on how to restore?

Actually, the one backup that CWM Recovery shows, I can't see under /sdcard/clockworkmod/backup/
I'm guessing CWM Recovery is pointed in the wrong directory..?

Cannot restore from nandroid

Im running fresh 0.5.3 and have the latest amon recovery, i can do a ext+nandroid backup fine but when i try to restore after i reboot, it gets hung on the
htc screen and will not load. Ive tried several backups and it will not work when restoring. Any ideas?
Make sure you're wiping the data, cache and dalvic before restoring the backup.
Are you sure the backup is getting created?
I know SteelH was posting yesterday about the NAND + EXT backup not even working with amon recovery.
I personally don't even know what it does, but all my backups are just "NAND backups and seem to work fine.
I'm assuming you used Amon_ra to create the backup and you're using Amon_ra to restore?
I created a backup with amon_ra and tried to restore with Clockworkmod and the backup doesn't even show up and vice versa. I found out by trial and error that backups created by clockworkmod have to be restore with clockworkmod and backups created by amon_ra have to be restored with amon_ra.
I don't know if that's the case for everyone, but it sure is for me. I'm running whitslack's 1.47 and Evolution V9.
Back to the Nand+Ext, maybe SteelH has figured it out, maybe send him a pm or search for his posts in the Q&A forum from yesterday.
make sure your batt has enough power
I am fully charged when i nandroid. It creates the backup and restores it but when i reboot it freezes on the htc screen. So this is a bug with the amon recovery image then? It would be nice to be able to backup & restore my ext apps because i use apps2sd. I could use titanium backup but nandroid is faster.

[Q] Does Acer Recovery Actually Back UP and Restore The ROMs?

Noob here. It doesn't "seem" like Acer Recovery is actually making backups of my ROMs. I'm really missing something either in terminology or execution and I'd like to understand what it is.
I don't know how to explain it other than to relate exactly what happened
I purchased one A500, but had to return it. I kept the backups taken with Acer Recovery, all Build A500_4.010.13_COM_GEN2
Got a new tab with Build Acer_A500_4.010.07_COM_GEN2
I immediately did a full backup:
Root (Iconiaroot 1.3)
Acer Recovery Installer
select "ClockworkMod Recovery rev1.3.4 by thor2002ro"
click "Install Recovery Image"
click "Yes" when asked to backup the current image!!!
Reboot into CW recovery.
Create a full backup: "backup and restore" -> "Full Backup"
The backup proceeded normally.
Rather than re-installing everything, I restored one of the backups from the old tab with Build A500_4.010.13_COM_GEN2
Backup installed fine, but instead of Build A500_4.010.13_COM_GEN2, I had Acer_A500_4.010.07_COM_GEN2, the same as the new tab.
I thought that was odd and I still don't know why it happened, but as I had just made a fresh new backup, I let the new tab go through the OTA updates to Build A500_4.010.13_COM_GEN2
Got everything working OK and decided to restore my new stock backup and make fresh incrementals of all the OTA updates.
Restored the original backup and now my original backup shows Build A500_4.010.13_COM_GEN2 instead of the original Build Acer_A500_4.010.07_COM_GEN2.
From these two instances, it doesn't "seem" like Acer Recovery is actually backing up or restoring the original ROM.
What is it that I'm either missing or don't understand about this process?
Thanks
If I understand the process, Acer Recovery will make backups of your recovery image. CWM does a full backup of ROM/kernel.
So, I'm not sure if I understand where you are restoring from.
If you restore through the Acer Recovery Installer, you should be just getting the old recovery image.
If you restore through the CWM menus after botting into recovery, then you are doing a full restore.
First.. it's not Acer recovery installer that's giving you the issue. The backup and restore are functions of clockworkmod.
The problem was that your flexrom did not get restored due to a bug that I demonstrated on thor's clockworkmod thread.
When doing a restore that restores data.img, it will also attempt to restore .android_secure.img and will fail, skipping flexrom which is supposed to follow. I bet you don't ever see the "Restore Successful" message after a full restore.
You need to either delete .android_secure.img from your backup set or restore flexrom separately.

PS. Clockworkmod does not backup anything from /data/media

So how to do a full backup of the image and restore if not from cwm.

Thanks Euclid,
Sorry about the confusion in the thread title. I thought Acer Recovery Installer had several functions: backup and restore recovery images and load CWM recovery to do the actual backup and recovery. Since I thought it did both, I assumed it was O.K. to use Acer Recovery Installer generically.
I did another restore to check what was done:
Fixing a500 Boot/recovery Checksums...
Running itsmagic
Done
Checking MD5 sums...
Erasing boot before restore
Restoring Boot Image
Restoring System
Restoring Data
Done
Screen refreshed to "Reboot Now".
As you said no "Restore Complete" message.
I wonder how many people including myself, assumed that the restore had completed successfully when they got the "done" message?
Both fixes worked well. I hope this helps someone else.
Below is the text from within CWM Recovery when .android_secure.img was deleted from the backup folder and a restore was run:
Fixing a500 Boot/recovery Checksums...
Running itsmagic
Done!
Checking MD5 sums...
Erasing boot before restore
Restoring Boot Image
Restoring System
Restoring Data
.android_secure.img not found, Skipping restore of /sdcard/.android_secure.
Restoring cache
Restoring flextrom
Restore Complete!
Restored my original stock ROM. So nice of it to ask me to update to a newer version immediately after the restore!
I did have one problem. I tried deleting .android_secure.img while rooted, using ES File Explorer with the Root Explorer and Mount File System options selected. I could never see the file on my external SD in the clockworkmod/backup
folder, so I pulled the card and manuall deleted it from my PC. I'm curios as to why this happened, but it didn't affect the result.
It was just as easy using backup and restore/advanced restore/your restore folder/ - Restore flexrom from within CWM Recovery.
I've read hundreds of post, in I don't know how many threads, sticky's included and never saw the advice about deleting .android_secure.img, manually restoring flexrom or even checking to make sure that you got "Restore Complete" I wish these things were part of an updated guide.
Lesson learned,
Thanks again
Just wondering, is there anyone working on a new recovery which will complete backups and restores without additional deletions, etc.?
bug was in thors post
The bug was mentioned.but I don't think there was much discussion about it.I don't think Thor acknowledged or tried ti fix.
With that said I could be incorrect. I however even with the bug think its a awesome tool.don't. Consider this as complaint.
Its like on page 3 or 4of the Thor recovery thread if im not mistaken
The blonde chic erica Renee
Yeah we need something reliable when restoring from backup. I tried once, cwm sees it but can't do the restore so I gave up even though I had all my apps backed up so did all one by one.

[Q] Can't restore CWM backup...any ideas?

So my Nexus was acting really slow (I'm on 4.2.1), so I decided to backup via CWM and then factory reset, and do an Advanced Restore to restore my data. I backed up and did factory reset, but when I went to restore my backup, it couldn't be found. Apparently 4.2 moved the default CWM location to search "data/media/" and I didn't have my backups there (obviously). So I moved the clockworkmod folder from /sdcard/ to data/media/ and tried to restore. It gave me an MD5 mismatch, so I researched that, found a solution, and did restore. Unfortunately, that bricked my Nexus 7 so I had to restore via the ToolKit.
My question is…is there any possible way I can restore my data to my now factory-fresh (4.2.1) Nexus 7 from the backup I made? I have the backup and the blobs.
Bump, the same thing just happened to me and I dont want to create a new thread. Is there any way to restore a 4.1.2 backup from a device running 4.2.1? Thanks in advance
EDIT: I solved it by booting into CWM and then pushing the rom, full wiping and installing again

[HELP] Screwd up nandroid

Hello guys!
I was updating from 4.4.4 to lollypop via OTA, then I realized that even if I run the stock ROM, I am still unlocked + root, meaning that the OTA won't run.
I did a complete nandroid backup via Wugs Nexus Toolkit, including data.
Then I wiped and flashed the new 5.0 via Nexus Toolkit, but when I tried to restore only the data it didn't work.
I decided to go back to 4.4.4. and do things properly, but now I'm not able to restore anything.
I am not bothered with the apps and stuff, but I had plenty of pictures which I forgot to backup, and I want to restore them. I even tried to access the nandroid backup files, but no success!
I was accustomed with the old CMW, where you had the .img files, but I got no clue on what to do here!
I add the picture of the nandroid backup folder on my PC ( I think the data files are splitted, but I cannot open them in any case, not even with 7zip).
The nandroid was executed via Nexus Toolkit, but I guess it has been done through TRWP.
Long story short:
1) how can I access the pictures inside the nandroid backup?
2) how can I restore a nandroid backup that keeps failing?

Maybe CWM does things differently, I don't know, but with TWRP, a Nandoid backup doesn't back up your SD card partition, so if you wiped everything, all your pics are gone. Sorry.
Yeah, I guess so.. Managed to recover something with DISK DIGGER (its an app, free on the store). Just wanted to write it here, so if anyone has the same issue can recover this way!

SM-G900F with TWRP 2.7.1.0 - Nandroid restore resulting in all apps force stopping

Hi experts,
I would very much appreciate some help regarding the following:
I have a Samsung Galaxy S5 SM-G900F with factory installed stock rom G900FXXU1BPA2 (Android 5.0). I used the SkipSoft Unified Android Toolkit 1.4.5 to root the phone and install TWRP recovery (2.7.1.0-klte as recommended by Unified Android Toolkit). I made a first Nandroid Backup and was able to successfully restore this backup (I restored boot, system and data to verify that Nandroid restore works). I then used Titanium Backup to restore my apps from another phone, and all was well.
A week or so later I wanted to modify something I wasn't sure I wanted to keep (using apktool). I therefore made a second Nandroid backup and then proceeded to make modifications to the phone. After I saw the result, I didn't like it, and therefore restored the second Nandroid backup. After rebooting, the phone gave a flurry of forced stops ("Unfortunately XXX has stopped"). It is not a bootloop but I can't do anything meaningful with the phone other than restart it.
To try and resolve this, I used TWRP to wipe cache and dalvik cache and rebooted. The phone went through the lengthy "Android is upgrading" process but the result was the same: all my apps force stop.
I then decided to try and restore the original first Nandroid backup (which I had been able to restore successfully earlier), and this resulted in the same issue. Since I have several backups of this first backup I was able to verify that the files were good. Also did MD5 checksum verification in TWRP and it all checked out.
Using Odin, I was able to restore a stock ROM from SamMobile (G900FXXU1BOL1_G900FOJK1BOL1_ILO) and after restart, the phone works as usual, but of course all my apps and data were gone.
I was then able to use TWRP to restore only boot and system from the second backup, so I would be back on the exact same ROM that my phone came with, and this worked just fine; the phone started as if factory restored.
I then used TWRP to restore only data, and this resulted again in the same problem: all apps force close. Note that this is a restore of data only to the same phone running the exact same ROM that the Nandroid backup was made on, and it still did not work.
I have been thinking about this issue and searching through the various forums but I did not find anyone having this same exact issue. Here are some questions I came up with:
1. Is TWRP 2.7.1.0 completely compatible with this phone and with Android 5.0? Would it help if I installed a newer version of TWRP? Would I be able to restore Nandroid backups made with TWRP 2.7.1.0 with TWRP 3.X?
2. Assuming my second Nandroid backup is not corrupt, is there a better (less intrusive) restore I can do of the apps? Can Titanium Backup read TWRP 2.7.1.0 backups and restore them, including SMS?
3. What could be the reason for TWRP 2.7.1.0 restore not to be working properly? I did activate the fingerprint reader after the first Nandroid Backup, but if that is the issue I would have expected that first backup (in which fingerprints were not yet enabled) to restore properly and it doesn't.
Would appreciate any help!
Thanks,
AH
That version of TWRP is pretty old, possible it doesn't fully support 5.0
Grab 3.0.0.0 from here (newer versions are not fully bug free yet)
https://dl.twrp.me/klte/
Flash .tar version with ODIN 3.10.7
TiBu can read Nandroid backups and restore apps yes
Not sure about SMS
The method you used to root and flash TWRP is not a usual method used here, most of us use ODIN to flash TWRP and then flash SuperSU from recovery
or use CF Auto Root to root, and then flash TWRP with ODIN
I'd flash stock again, factory reset, and then flash TWRP and SuperSU, then try restoring your apps with TiBu

Thanks *Detection*! I installed TWRP 3.0.0.0 as per your instructions and restored just data. Same result as before.
Then I used TWRP 3.0.0.0 to restore the entire backup including system, boot, recovery, and data. Same result (of course I lost TWRP 3.0.0.0 and was back on TWRP 2.7.1.0).
This exercise was useful for one reason: I now know that TWRP 3.0.0.0 is able to read Nandroid backups from TWRP 2.7.1.0.
This is quite crazy but I seem to be unable to restore a full Nandroid backup and get a working system.
Am going to try Titanium Backup.
Thanks again!
AH
