I've rooted my Huawei Mediapad T5 lately.
But now i think I have encountered some problems. So I've tried to reset the tab.
(using EMUI btw)
I tried to do so via:
- System - Reset
- Recovery (deleted cache too)
- eRecovery (download & wipe/reset)
But it seems some things still keep stored somewhere. Things like USB-fingerprint etc.
And some other problems I had.
So I'm wondering. How can I best completely wipe an Huawei device?

I have tried several different Rom Managers without a problem on my G Tablet. Have been using TNT lite. Recently I switched to Vegan Gingerbread edition, but when I went to backup my old Rom (TNT Lite) the backup hangs on backing up the cache. I tried wiping the cache and formatting the cache, but it always hangs indefinitely.
I installed Vegan Gingerbread anyway and it appears to work perfectly, yet I still cannot backup the rom with Clockworkmod (always hangs on the cache). If I try to look at the cache partition in filemanager, it shows empty, though I am not sure it is actually recognized. I can't seem to do anything with the cache at all.
I am, by no means an expert, but have had no problems with this before. Backup did work before the recent problem.
Since everything is working with my G Tablet now, I am not sure there is an actual problem with the cache, except that I can't backup the Rom without it hanging on the cache. This may limit my ability to load other Roms in the future.
Please help.
I have the exact same problem. I've had no issues backing up and restoring ROMs myself, but now I'm having issues with my tablet not being able to format or restore cache. I can install a ROM, but it takes a long time to actually load up - it can sit on the first splash screen for easily 5 minutes before it boots into the ROM, wher as before it took around 1 minute or less. Are you having this slow boot problem as well, or are your problems strictly with the cache? I'm going to continue to look into it (currently looking into using nvflash to do a restore and see if that irons things out), so I'll let you know if I come across any solutions. And please, let me know if you do as well.
hey guys i had the exact same problem before but nvflash fix what ever the problem was and the newly installed cwm work as it should. are you getting "ANDROID" screen right before it goes into cwm?
I am not getting the Android screen before ClockworkMod, but I generally boot with the power/vol + combo. I also have not changed Rom's recently, so I am not sure if this would be a problem or not. I do not have any boot problems that I am aware of, nor can I see and performance problems resulting from my inability to format the cache. The only problem is I can't wipe the cache, backup the rom, or format the cache as it stops on formatting cache partition and therefore can't continue the backup process. Other than incomplete backups I am not sure what problems this actually causes. Do you know.
I haven't used NVFlash yet, but I guess I will have to give it a try. Am I simply restoring the ROM to factory state and starting over or is there some other process I am looking for? Unfortunately, I did not get a proper backup of my original factory rom, so I will have to rely on downloads. Any tips on NVFlash would be greatly appreciated.
It's Fixed! Thanks for the tips.
Here is how I did it:
Ran NVFLASH - it was much easier that expected. It fully restored the original stock Rom, but I still had trouble with clockworkmod. Mostly it would not boot into recover mode. I then re-rooted the tablet using the Update.zip method, Then everything worked fine including backup and cache format.
I continued to restore my tablet and tried the backup each step of they way.
I installed Vegan Gingerbread - Worked flawlessly
I reinstalled MyBackupsPro and all my apps and Data - Also, worked flawlessly
I reinstalled Rom Manager - also worked flawlessly.
I used Rom Manager to upgrade ClockworkMod to 2.5.1.8 - then the backup/ format cache problem reappeared.
I then ran Rom Manager again and selected flash alternate ClockworkMod. It restored version 2.5.1.1. Then the backup and format cache worked again.
It appears that my Gtab does not work properly with Clockworkmod ver 2.5.1.8 and that was the entire problem.
Since Version 2.5.1.1 works great, I see no reason to upgrade this again and consider my problem fixed. I hope this info helps others
I am a noob looking to try out the touchwiz rom,
My 10.1 is encrypted and trying to remove the encryption using the menu option in settings- factory data reset - it just reboots like nothing happened and asks for the password (I wanted to turn off/get rid of the encryption). I get a box open and android icon for a brief moment at reboot.
Using ClockworkMod Recovery v4.0.0.4 the wipe/factory reset option selected and it errors on the mounting /data. Can't mount or format /data too.
This 10.1 retail has a locked bootloader and is rooted.
Anybody? So far not bricked, ,
got it
I used odin and followed instructions here- http://forum.xda-developers.com/showthread.php?t=1119492
I lost clockworkmod and it did not recognize my password on reboot, but it did let me wipe everything.
You might have to wipe user data to get rid of the encryption. But you will loose all ur data
<bump>
I'm having the same trouble - and no amount of flashing various stock or CWM recovery gets me to a point where I can actually format / remove the encrypted partition.
The device had been rooted - and then encrypted - and it wasn't until I attempted to reboot into recovery with CWM (hoping to perform a factory reset) that I got into a boot loop.
Days, and countless flashing later - I'm no closer. The one thing I find interesting: when I flash particular (CWM) recovery / images, and reboot - I actually get the 'pre-boot authentication' page, which still accepts my encryption passphrase. It's after this point - that I'm just staring at a black screen.
Perhaps nvflash might be the right tool for the job - so off to learn about THAT. Every day, a new adventure - and another twist down the rabbit hole.
Thanks in advance to anyone with some insight / links / tips to share.

I'm facing what I think is a similar problem on an AT&T Galaxy s3 i747 with Paranoid Android. I had to encrypt for work email, and ever since then it regularly reboots whenever I try to do something (~25 second effort)... when I do the factory reset, or try reflashing a ROM, it seems to reboot before the action completes... Can you advise how I might solve this?
I've already tried CWM to redo everything... Factory reset does not complete as it always asks for the encryption password once started again... I just want to get back to unencrypted please. Any ideas? Maybe ODIN CWM then try a new install? formatting my SD card? Thanks in advance...
Hi, I had the same problem as above.
I was unable to factory reset with CWM recovery as it couldn't flash the data partition or sd card and couldn't mount them.
However, using the stock recovery, the factory reset and formatting worked fine returning back to an unencrypted device.
I have a Rooted Pantech Discover P9090 with ClockworkMod 6.0.2.8 recovery from Here. After which I proceeded to test out the phones "secure" (encryption) features. Now that the phone is encrypted, however, I cannot remove the encryption because I can not perform a factory reset. When attempting a factory reset from within the UI the phones attempts to reset as normal but at the point where the phone turns off and comes back with the android screen and a loading bar at the bottom the phone restarts. Doing a factory reset from the recovery fails do to not being able to load /data, /system /sdcard. Is there anything else I can try/do?
Other info:
Android Version 4.0.4
Still nothing.
Update 1: Flashed over to JB in hopes that it would help. Nothing. Still looking for solutions.
Does anyone have any of the stock files. Hopefully the recovery.img for this phone?
Hi guys i tried using twrp 3.1.1.0 and it says password for unmount data. Also my phone in settings says encrypted.
I tried wiping data cahce, etc but that diidnt worked also using default_password but that diddnt worked as well

Have you try reboot the phone into normal Android system? and later try reboot into TWRP, I read somewhere it might work.

Hi guys the solution for my me was doing an entire wipe of everything except recovery then flash rom, it seems that the stock rom of le max was causing that
What was your ROM in the beginning? Was it Indian ROM? Did it have the update manager? Which ROM did you flash after wiping everything except recovery?
I bought the phone from geekbuying with EUI version 5.8.019S (Stable), BUILD: FGXOSOP5801910121S release-keys. It looks like the latest vanilla Indian ROM, but it is most likely vendor-modified since the phone was received unsealed and there is no update manager. The main problem is the encryption - phone is encrypted right from the start without any password or PIN prompts. Factory reset allows to set up everything from the start, but the phone is still encrypted. TWRP asks for a decryption password. I have tried multiple vendor and default passwords with no luck. TWRP factory reset does not prevent the encryption.
This question keeps coming up in forums since people do not seem to search for similar questions. Well, I did. Therefore, I will try to assemble the list related to the encrypted ROM:

https://forum.xda-developers.com/le-max-2/help/benefit-form-leaving-x829-to-indian-t3609698
Proposed solutions:
CASE 1: No Update manger + encrypted ROM
Since it is a vendor ROM, you can try flashing a clear stock ROM from recovery that can be downloaded from the official LeEco forum http://forum.le.com/in/eui_detail.html?euiid=206 . It might not directly resolve encryption, but will make the update manager appear, which can be used to upgrade to ROM w/o encryption. If you want to stick to the Indian ROMs, but want to remove encryption - see below
More reading here: https://forum.xda-developers.com/le-max-2/help/update-eui-t3480614
CASE 2: Encrypted ROM
You most likely have an Indian ROM. You can try reinstalling the ROM (TWRP) and immediately wiping the data partition from TWRP. Some users report success with this.

One user has found that upon multiple resets with TWRP the encryption seems to be ignored

Another user suggests Chinese ROMs since they are likely not to encrypt the files. In other words, updating to a Chinese ROM might help.

Hi there,
I've reinstalled my Lineage OS in May and have recently installed the latest upgrade. Today, I was using my phone just fine before a subway trip, then after it was stuck in a boot loop (lineage OS circles). My guess is that I accidentally restarted it.
What is the procedure to repair the phone without loosing the data?
I tried:
- Reinstalling recovery, lineage, MindTheGApps in that order
- Wiping the cache partition, wiping the dalvik cache
So far I have not seen any progress. Am I missing something?
I really want to avoid wiping my data as I just set the phone up two months ago.
Did you try dirty flashing the ROM zip by only Wiping the System partition but not Data? I use NikGApps and its not necessary to reflash it during a dirty flash but I flash the latest GApps build in any case. I pretty much use crDroid exclusively and dirty flashing works reliably. Not encrypted though.
Ok, so I did the following
Action -- What I think it does
Install TWRP recovery via fastboot -- to selectively wipe partitions
Wipe System -- to remove system files from the previous update
Wipe Cache & Dalvik cache -- to remove cache files that have previously been written on startup
Install lineage os -- to install a clean OS
Install MindTheGapps -- to install the Google subsystem
System reboot
Files used:
twrp-3.6.2_9-0-beryllium.img
lineage-19.1-20220618-nightly-beryllium-signed.zip
MindTheGapps-12.1.0-arm64-20220605_112439.zip
Again with:
lineage-19.1-20220716-recovery-beryllium.img
lineage-19.1-20220716-nightly-beryllium-signed.zip
MindTheGapps-12.1.0-arm64-20220605_112439.zip
Still caught in the boot loop.
I feel a bit lost here.
I did nothing special. Just installed the newest Lineage OS from the GUI and then apparently accidentally restarted it (or it crashed). This should be a common use case. I would expect there to be a guide or wiki that explains and solves this. But from my own Google searches I mostly see recommendations in the line of try wiping and reinstalling.
I am pretty sure, my data is encrypted. Does this mean I am screwed? (i.e., all not backup-ed data is lost?) Was flashing a new Lineage OS & GApps the step that doomed me?
Before the bootloop did you have TWRP installed instead of LOS recovery? Flashing the OTA update via TWRP can be problematic.
I had recovery installed. I reinstalled the Image from Lineage recovery. After this didn't work I tried it with TWRP.
Did you try flashing the build you were using before the bootloop occurred? No clue otherwise how to resolve this. Hopefully someone else can help you out.
Yes, first I tried installing only MindTheGapps, then lineageOS (last version I had) + MindTheGapps. And I tried a number of recent releases.
I also tried the most recent version and now I cannot install earlier versions anymore: "Current SPL: 2022-07-05 Target SPL: 2022-06-05 this is considered a downgrade".
I gave up. Reinstalled everything. Lost a ton of messages for which I did not have the right backup.
Depressing. Nothing I did was special. So I can expect this to happen anytime. I will improve my backup. But still, in the long term I need to find something that is reliable.
Thanks @amn1987 for the suggestions.
Use Swift Backup for backing up apps and their data, SMS, call logs etc. on a regular basis. Works very reliably. You can backup messages to Google Drive as well. Probably can schedule the backups.
