Hi all,
I tried to update the custom ROM on my A200, but in the process, the data wipe failed.
What I did exactly, is use ROM Manager to load the latest JellyBean CM ROM for A200, selecting the option to wipe the data partition (do a factory reset). My device rebooted, and it started trying to wipe the /data partition, but it just stopped right there. No error or anything, the system just hung there for 2 hours before I turned it off. As I feared, the system was rendered unbootable.
However, CWN Recovery *is* still available, which I guess is a good thing. So, I can boot in recovery, but I can't really get it to function. I tried formatting the data partition again - system hangs. I tried installing the image from sd card - system hangs.
Does anybody know how I can recover from this? It seems to me that there's nothing *really* broken, just that my data partition is corrupt somehow -- and I suppose there has to be a way to recreate these partitions.
Thanks!
I've had CWN Recovery run for 24 hours now, and still nothing. It fails to format the data partition.
Anyone knows how to tackle this problem?
I was running 4.3.1 and decided that I wanted to use encryption. So I encrypted my entire phone and all was fine. Then today I decided to try out 4.4.1. I've made multiple attempts at wiping everything, but data and cache both seem to be unmountable in both TWRP and CWM. I've tried restoring the factory image but it just seems to hang on the boot animation. Any ideas?
I tried restoring a nandroid backup on my phone and have been having trouble ever since. Upon restoring my nandroid backup, I restarted my phone but I couldn't get past the Samsung Splash Screen. So I started troubleshooting:
1) I restarted my phone, booted into recovery (TWRP), and wiped Dalvik Cache, System, Data, Internal Storage and Cache. I then tried restoring my nandroid backup again. However, upon rebooting the device, I still couldn't get past the splash screen.
2) I installed Heimdall for Mac (like Odin) and flashed the latest TWRP recovery.img (openrecovery-twrp-2.6.3.1-jfltexx.tar). I tried to restore the nandroid again, but I still couldn't get past the splash screen.
3) I tried doing a fresh install of cm10.2 stable and still nothing.
Please, any help or direction would be awesome

I'm in the same boat. Boot loop, can get into CWM recovery, but can't do anything to get it functional; factory reset, wiping cache, reflashing koshu's 0.91 build, none of these work. Only other suggestion I've seen is getting an ADB shell while in CWM and checking the partitions are not corrupt. As per this post:
http://forum.xda-developers.com/showpost.php?p=39917591&postcount=7
At the bottom of that thread there's reference to a possibly related Lenovo thread of people suffering similar problems, which was closed in Feb with a message about an extended repair program, valid until August.
It'd be a shame if it's a hardware issue, that we can't claim on because we're running custom software... you have to accept that risk when you decide to flash a custom ROM, but I don't think I'll be buying Lenovo again; mine's been repaired once already, and now this.
Hey folks. I'm hitting a brick wall trying to figure out this issue and I'm hoping someone will know how to fix this.
I have a Galaxy Tab A 8 (SM-T350) that I rooted and successfully flashed with first crDroid, then Lineage (both Android 9.0) using TWRP. I had made a backup before attempting this just in case I wanted to revert to stock.
Well, that didn't go as smoothly as I was hoping. Ever since trying to restore my backup, I've been stuck on a continuous boot loop that I can't seem to fix.
I keep getting "E:failed to mount /efs (Invalid argument)" and "dm-verity verification failed. . ." no matter what I try. I've googled the error and tried every solution suggested but I still can't get it to boot.
Any help at all would be greatly appreciated. Thanks.

Ignore the EFS error its probably a red herring. Your issue is dm-verity.
3 ways around it. Return to complete stock, including wiping the data partition or flash root (magisk suggested) or disable dmverity using one of the zips out there.

Thanks for the reply ashyx.
I've done two of the three things you suggested. I've tried returning it to stock using an image matching my exact model, and I've tried disabling dmverity. I've also tried rooting it but using a method other than magisk.
The flash seems to go well enough, but then I get stuck at the Samsung logo whenever I try rebooting into the system.
I've tried waiting, thinking I'm just being impatient, but it doesn't ever seem to get past the logo. I've tried googling ways to fix it being stuck on the logo but nothing I do seems to work. Is there any other way around it?
Side note: I've been able to flash Lineage OS again and might just have to stick with that if I can't flash it back to stock. Do you know any resources for replacing the default apps? I've tried GApps but I was wondering if there's a similar Samsung installer?

You need to wipe the data partition, aka factory reset before or after installing the stock firmware then it will take anything up to 15 mins to boot.

I've tried leaving it for a few hours in hopes that it would boot, but unfortunately it stays stuck on the logo.
Is there a way to check where or why it's getting hung up?

Did you back up the efs partition with twrp?
If so try restoring it.

I did and I have been restoring it.
So far, this is what I've attempted:
Flash TWRP (twrp_3.1.0-1_sm-t350_18317.tar using Odin3 v3.10)
Reboot into recovery
Wipe everything from tablet
Format tablet
Reboot into download mode
Flash stock image with Odin
Reboot into recovery
Wipe dalvik cache
Restore backup (including efs partition)
Wipe dalvik cache (again)
Reboot
Get stuck on Samsung logo (left it for hours with no change)

Don't restore everything just EFS No need to keep wiping dalvik it serves no purpose when formatting or wiping the data partition.
Also FORMAT not wipe the data partition (note this wipes internal storage)
If it still doesn't boot install the combo firmware. Let it boot, factory reset from settings then reboot to download mode and install the stock firmware again.
