I ran a custom ROM today (10-13-2011) and wasn't completely satisfied, so I tried to flash back to my last working nandroid backup that I had created earlier this morning. Unfortunately, it got stuck while loading one particular file. After several battery pulls and several attempts at installation I ended up flashing a nandroid I had created 4 days ago (10-08-2011). This flash was successful which indicates to me that clockworkmod rom manager must have created a corrupt nandroid when I made one this morning. This is a bit disturbing to me bc I have OCD and now I'll be wondering if the nandroid backups I make from here on out are jacked up. Do you guys know why this may have happened? Or do you know a way to tell whether or not a nandroid is corrupt (before trying to flash it)? Should I be concerned with any of this at all?

Don't know why this happens, but it has happened a few times to me

It doesn't happen to you every time does it?
How long was it stick on a certain file? Mine sometimes seems to get hung up, but will continue after a minute or two...
It was hung up on that one file for like 5-10 minutes. When I flashed the older backup I didn't have that issue though.

Update: About a week ago I had this same issue again. I made another nandroid backup, tried to flash it, and discovered it was corrupted and had to (yet again) flash back to that backup I made on 10-08-2011. Today (10-31-2011) I tried to make a backup and it actually successfully flashed after install. I was happy to see that happen....however I'm still disturbed by the inconsistancy I'm now experiencing with Clockwork Mod ROM Manager. Do you guys have any explaination for why I may be having these inconsistent issues?

I'm just like you with the OCD about this...but I've luckily never had it happen to me.
I'm probably wrong on this, but it seems to me that these issues mostly started sprouting up on the 5.0.2.0(that's right, isn't it?) build.
What I've always done since hearing about this the first time is create a backup...and then restore the backup without even leaving cwm.
That way if MD5's don't match...(hopefully just that) I know it right away.
And if it fails on a single file...I can hope that it isn't a crucial file and my phone will still boot.
It gives me a little blanket of trust in my nandroid, at least.
I too must report many recent problems with nandroid backups (using CWM 5.0.2).
I take a full backup every week or so, as well as before doing something like changing a ROM. A couple of the backups are stored on my SD card, but the rest I push up to my NAS via FTP (to keep a longer history).
Yesterday I went to go back to a point in time only to find out that the backup didn't work (failed MD5 checksum). I managed to get a recent backup restored, but it had something broken in it, so I opted for a fully working backup. I ended up going through ALL of the nandroid backups that I've taken since getting my phone, and none of them work anymore!!! (even the broken one that did manage to restore once yesterday).
This is super weird, as I know that some of these backups were good as I have already restored them successfully!
I can't help but wonder if my file transfer method is playing a role here. First I was using FTP over WiFi, but then I switched to USB cable to PC as Flash drive -> NAS via wired Ethernet.
Whatever is going on here... it is really a serious problem. If you can't count on a full system backup like this, then there is really no point to it.

Hey all,
I was trying to get OTA2 installed while retaining my root and long story short I ended up formatting my /system in CWM thinking it would rebuild the factory image. Now of coarse my system won't boot. For some reason I am also unable to mount /sdcard. Is there anyway I could restore my system?
Thanks for any help!
restore \system of your CWM backup
I don't have a CWM backup . I know, a real bonehead move. If anyone could help me out with a clean CWM backup I'd be willing to compensate.
Edit: BTW I have a 16gb US version of the TPT.
Is it even possible to flash someone else's CWM backup?
Could I use the full image that Lenovo took down, found here?
I don't suppose there's an nvflash image for this device...
While I'm not sure, it might be possible to use that full image. Certainly worth a try. You might try asking on that forum, if you haven't already.
Yes, It is possible to restore from someone else's backup. I, in the past have copied my backups to my pc when they were too much and If i needed them, I just copied them back to external_sd/clockworkmod/backup/ and voila, it would appear for restoration in CWM.
I may be wrong, I do not believe that region should have any effect but to be safe (since you already made one mistake ) restore your US version with a US backup. I have a UK version and I would have uploaded a backup for you if you couldn't find a US one but unfortunately, my tablet is at the lenovo repair centre, being treated for the dreaded micro usb port failure. Hope someone here can help with a backup.
Thanks for the advice!
I downloaded that full image, but I could not get it to flash in the traditional sense. I extracted it and copied the system directory to my system partition and the tablet actually boots now. However, wifi does not work, whenever I press any of the menu keys a red frame flashes around the screen, and I cannot go to the About section of the settings to try to download updates or anything, it just crashes. I am also unable to update to OTA1 via zip in CWM, it gives me:
Code:
assert failed: file_getprop("/system/build.prop", "ro.buildfingerprint") == "Lenovo/ThinkPadTablet/Indigo:3.1/ThinkPadTablet_A310_02/0024_0065_US:user/releasekeys" || file_getprop("/system/build.prop","ro.build.fingerprint") == "Lenovo/ThinkPadTablet/Indigo:3.1/ThinkPadTablet_A310_02/0037_0075_US:user/release-keys"
Since you still need a lot of help anyway why don't you try manually installing all of the updates up to OTA 0076. You have to have all the updates before it flashed first. Link here:

The nandroid backup would have to be of a factory restore, correct? Otherwise, all accounts/settings, etc would be within the backup as well.
I wasn't planning on doing a factory restore any time soon, but if the CM9 ICS port releases is soon, I can make one then as I have the same model and region as you.
I'm just really busy at the moment due to school and I rely on my tablet for school!
That would be the only safe way to let someone have a backup.
toenail_flicker, Thanks for the suggestion, I'll start from the top of the list and work my way down.
obscure.detour, being a student also, I completely understand. Luckily I just bought a Livescribe pen to offset my need for my TPT for the moment .
In the mean time, in case anyone else would be willing, you could also take a backup of your current system, do a factory restore, take a backup of the clean rom, and than restore your original image.
Thanks!
LOL You make it sound easy, but for a CWM noob it's a dicey thing. Never restored anything. Perhaps someone with more confidence in CWM than me can pull it off for you.
I know letting someone have a backup that contains personal info my be tricky, but if you've got time (couple of hours) on your hands you can backup your current system, do a factory reset, and since a factory reset only affects data, it wont wipe your root or CWM. you can then make a CWM backup of the newly reset rom, copy it off the sd card and restore your earlier system which you backed up.
This would save the OP having to start installing the OTA updates one by one.
Like I said, my tablet is away for repairs, otherwise I would have helped him. Or, maybe that's a good thing cos its certain that my tablet's main board will be changed, thus its going to be a fresh android installation on it. when I receive it in a couple of days, if you're still in need, I'll try to reroot and install CWM so I can send you a backup.
Much appreciated darkhandsome18! Installing the OTA's failed . It looks like the image I found is actually a test build. Even the earliest patches do not recognize it as a viable base to install on.
Did you ever get someone's backup? If not I can make one for you today. I am on OTA2 though, were you updated before you wiped system?
Here is a CWM backup from my 32GB US TpT.
Extract the file onto your external sd card in the folder /clockworkmod/backup/
Reboot into CWR
Select Restore Backup and select my backup (You can use advanced backup to restore individual parts or just the normal restore to restore everything, which will be factory reset US OTA2 with root)
Hopefully everything will work properly and you will never format your system partition without a nandroid backup again.
I have it on my Dropbox for now but will delete it in a couple of days because it takes up a lot of space. Let me know once you have downloaded it.
If you don't have a Dropbox account then sign up here and we'll both get an extra 250MB of storage space.
jhankinson, thanks! I was not on OTA2, would that be a problem? Also, I'm having issues backing up my current setup, I got ICS running. CWR gives me "Error while backing up boot image". Any ideas?
I'd like to backup my current (semi-working) setup before attempting to restore yours. Thanks again for uploading that!
I finally got it to work by remounting my sdcard in rw using ADB in clockwork recovery. That backup seems to have worked flawlessly jhankinson, I can't thank you enough!
This is great news! I knew I couldn't help you, but so glad GodfatherIP was able to help you. He helped me a great deal, too, recently.
Who is GodfatherIP?
I am returning my NC - dropped it, cracked the frame and volume keys no longer work. It's covered under my extended warranty, thank goodness!
I was running the MiRage rom on my emmc. I was able to restore to stock using TWRP (again, thank goodness for a touch screen recovery!).
I had redone my partitions to have 2 GB for my apps. Not being a developer, just someone who knows how to read instructions well, I'm wondering if when I restored my NC to stock, did it also restore the partitions, or is there something else I need to do before I send it back?
It would not restore original partitions... you will need the zip file for that as well.
So, if I follow the instructions in this thread (using TWRP instead of CWR) and restore to 1GB data/5 GB media, do I then need to reflash B&N stock image afterwards? Do I need to wipe before restoring the partitions?
shouldn't need to reflash stock... wiping not necessary.
@dizzyden - I have seen so many of your posts in the NC forum. Always helpful. Always with answers. Thank you for your help in my time of need.
I recently updated to 0089_US using CWM patched version & proceeded to perform the device encryption.
Everything went smoothly & the TPT performed as per normal.
However, three days ago, it suddenly started to act up & after a reboot, I started encountering a series of Force Close repeatedly on almost every other application I try to use.
Nothing I tried to do to recover from this problem resolved the problem.
As a last resort, I backed up all the data that I can access & performed a factory reset (Privacy | Factory reset).
After the factory reset, I setup my TPT & tried to perform the encryption again.
This is when I discovered that something is wrong.
I was not greeted with the usual dialogue that I encountered in the first successful encryption process.l
Instead, after confirming that I want to encrypt the tablet, all I get is a green android icon without any indication of any process going on in the background.
Pressing the Home button brings me back to the desktop minus the taskbar (Back, Home & Task switcher) at the bottom.
After the screen or screen lock timeout, the TPT will lock. Unlocking it will bring me back to the green android icon.
This is how it looks like:
Link to picture
This is how it should be if it was working normally:
Link to picture
I've already factory reset the TPT 3-4 times but each time, the situation is the same.
I've just tried reflashing 0089_US again & the situation has not changed.
Can someone advise me what is wrong here?
I've not placed any data back on my TPT at this point.
Please advise me as I need it to be encrypted.
Thanks!
Update: After reading this thread, I got the idea that if I can get my hands on a stock 0076_US NANDROID backup, perhaps I can get it back to the original state. My own NANDROID backups did not work because the data & system files did not successfully convert to .img files after the backup. I got an error that the CWM backup failed to generate the data backup because /sdcard/.android_secure cannot be found.

PS: I posted this at the Lenovo forum here but did not get any response.
Can I use CWM to restore system.img alone?
I'm wondering if its worth a try to restore a system.img to my TPT? I've since restored my data & apps using Titanium Backup.
I got a feeling that the system files are somehow not properly restored when performing the factory reset. Of course I would need a system.img file to restore so anyone who has a 0089_US system.img file to spare, I'll greatly appreciate it. Not sure if I'll lose root in the process.
Anyone with any clue as to what I'm facing, please point me in the right direction.
TIA!

Thanks!
I just saw it & am downloading now as we speak.
Are there any issues I should be aware of in using this Nandroid backup to roll back to 0075_US on my updated 0089_US TPT?
Please advise me accordingly.

I recently rooted my phone and tried a few different roms. I'm currently on cyanogen mod 10.2. I used cwm to backup my original ROM. I copied the backup file to my computer and uploaded it to my dropbox. I formatted my SD card since it had a lot of junk on it. I copies them back and now they aren't being recognized. This is my original stock ROM and since this is my first time rooting I really want to keep a stock ROM on hand for easy access incase I mess something up and need my phone to work properly. Thanks for any help. Its also a Samsung s4 i337m from fido.
can you see the backup and it's just not letting you restore it or can you not see the backup at all?
i'll tell you to keep researching and troubleshooting but if all else fails, odin back to stock, reroot, install cwm and make a new stock backup again.
Its not appearing in cwm at all unless i have a restore that was on it post format and not copied off the computer. Like if I make a backup of my current ROM the stock one will appear and just hang in checking md5. If there are no backups other than the original stock one it isn't being recognized. Also it worked before I formatteebthe SD card.
when you formatted the card and then replaced the cwm backup, where did you place the backup?
for example: 0/clockworkmod/backup, /clockworkmod/backup, etc.
if you make a backup now, where does it save the new one?
i'm just running through the bases here.
Sorry I don't know the exact locatiotion but I just dragged and dropped the "Clockworkmod" That cwm created when I made my first restore to my PC. Formatted the SD card and just dragged and dropped it back to the SD card. The new restore saves in the same folder also.
i'm assuming they're both in something like sdcard1, extSdCard or external_sd /clockworkmod/backup.
if so, and you didnt change cwm versions (i.e. from 6.0.3.6 to 6.0.4.4), then something may have been corrupted when moving the backup folder back and forth.
Yes that seems about right. I didn't change anything on cwm, unless my ROMs did. If it is corrupted will it just hang indefinitely or is there a chance it can work? And is there any other way to do a restore?
i'm no recovery expert but if your backup is corrupt than i dont imagine there's a fix for it.
i accidentally deleted my stock backup a couple phones ago. in order to have a fully stock backup on the sd card again (in the event i needed/wanted to restore to the original factory setup), i had to odin back to the stock firmware and start over.
Do you know any good guides on how to do that?

Try to re-downloading from drop box. Could have gotten corrupted during the download process.
Download it straight from dropbox to the SD card through the phone?

true story.
report back. cheers
Nope, no luck. It just hangs at checking MD5 Sums. I tried the backup i made for foxhound 2.0 and it did the same thing.
edit: It worked it was just hanging for a good 15 minutes though.

Can you have cwm not check for the md5? It's been awhile since I've used cwm. I use twrp.
Edit, doesn't look like you can. I just flashed cwm to see. Was the foxhound nandroid one you just made and it still doesn't restore?

yeah, thats what i was gonna ask: if you've made one just now and tried restoring it.
Ok thanks for the help but the problem resolved itself after letting ti hang until it did something. It worked after about 15 minutes.
edit: I just rooted the phone a few days ago and I'm all new to this, so i figured after it not doing anything for 5 mins with the dead android on the screen was bad. Thanks for the help.

Good, yea a restore and reboot can take longer than you think. And waiting seems like forever when you're expecting it to boot. You'll get used to it.
