How to decrypt Internal storage partition? - Huawei P9 Lite Questions & Answers

So I installed Elite ROM for my friend, after few days device randomly shutdown and factory resetted itself. It was impossible to get past introduction setup. I reflashed the ROM without initial setup option and got it to work.
Turns out the Internal storage got encrypted, Yalp store stopped working because the app couldn't write to storage. Same for browser downloads which don't work or camera photos, which can't be written into internal storage, etc, etc. How did it got encrypted and how to get rid of it? I tried formatting it with TWRP and it didn't mount. How else should I approach this? Maybe there's a fastboot command or something?
The device is usable since login information for apps persists but Play Store hardly works because it only install apps in the background after the screen is turned of for 5 minutes or so and only F-droid apps with privileged extension install normally.

[Q & A] Play Store Error - Couldn't install on USB storage or SD card

[Q] The Play Store gives me this error message when I try to install certain apps: "Couldn't install on USB storage or SD card." What can I do to install those apps?
[A] *After receiving the error message*
1) Go to your phone's Settings > Storage
2) Unmount SD Card (your external SD card)
3) Download/install from the app(s) from the Store again
4) Go back to Settings > Storage - then Mount your SD card again (or reboot)
5) Enjoy the app(s)
Background: I thought I was encountering some compatibility issue because the Note 3 was newly released and I had just acquired mine. I had also received the error when trying to update one of my apps. It is still not clear to me why it occurred and this is the only solution that fixed it for me.
Could be SD going bad, check LOST.DIR for any files, if anything there, it is already getting corrupted.
Checked, nothing in LOST.DIR

This just showed up , and i formated my sd but it fixed nothing . After re mounting it , the problem was still there . I removed it completely and then rebooted . The problem is gone , but could the problem come from the sd ?

Sounds to me like a ROM problem. I started experiencing that problem today when I install NV ROM for M8
The play store is an annoying piece of ******. I can install everything except Zooper Pro (RPC:S-3 error). Thus forcing me to use a cracked apk, simply because nothing else works!
Anyway, as for your errors. Tried deleting the data and cache on the Play Store and Google Play Services? Do you have enough space available?
sollution 2
here is some more info
it seems like it should be easy to fix fo google :/

Same problem. I've noticed the problem isn't the sd card, because i've changed it and could not install certain apps anyway.
I guess it's a rom problem. I'm on Blekota S5 v10 now, that's causing this issue. Yesterday I've flashed my rom stock backup, and every thing was ok.
Although if you are rooted first
1.)Unmount SD Card
2.)Download Link2SD it will requires root get it on play store for free
3.)Download your favorite app that get some errors
4.)Mount SD Card
5.)Put the app from external to SD using Link2SD
6.)Profit
Works
Thanks for the answer!
Just Backup and Format

Hi There... The problem with Unmounting and Mounting the SD Card is that since I have my music saved on my SD Card I have to choose a New Ringtone and all my Alarm tones all over again each time I do that... So I backed up all my Music to my Phones Memory, Formatted the SD Card and Voila... Now I don't have to keep Unmounting and Mounting the SD Card every time I want to update an App... more so I only had to go through the hassle of choosing the music once after the format... Hope this helps

[Q] Internal SD wiped clean, any way to restore?

I recently received my new S5, I rooted the phone, and also bought a 32gb external sd card. I realized that with KitKat 4.4.2, google has prevented apps from writing to the external SD card. I looked up workarounds to this problem and came to this:
trendblog.net/fix-kitkat-sd-card-write-restriction
I applied the fix to my phone, editing the platform.xml file, rebooted, and realized that my INTERNAL SD folder has now been wiped clean and is now empty. A lot of apps stopped working, including youtube, google, samsung keyboard etc, with the message "unfortunately <insert app name> has stopped". In particular, the MyScript Resource Manager constantly stops, and gives me that message. I am unable to go online either even though am able to connect to wireless and data networks.
I have tried different ways to solve the issue, including factory reset, and flashing stock rom, but my internal SD folder remains empty.
Does anyone have any idea how to solve this issue?
I've just had the exact thing happen. We're you able to fix?

internal and external memory got wiped / including all my data.

Hi guys,
First of all, great forum and great place to learn a lot of stuff about ROM's.
I have been using the forums here for a while.
Now I have a problem with my Galaxy S 4.
Galaxy s4 :gt- i9505 (Beglium)
16Gb version
Custom Rom: optimized cm 12.1 -20160118
android 5.1.1
I had some problems playing my music files on the phone, so i connected the phone to my PC.
I deleted my MUSIC folder from my EXTERNAL card.
Then I saw There are a lot more random folders in the ROOT of my EXTERNAL card.
So I deleted the LOG files, some maps that where for AD's (like GO sms), etc.
As far as I know, I did not delete any system files or folders.
While I was in the external card, connected to the PC, I saw that my INTERNAL card had wheeeeyyy much more free space than 5 minutes before. ( normally 0.9Gb free... suddenly 5.72GB free)
So i disconnected the phone and reconnected it again.
Again same thing.
Again disconnected it and on the phone I could not find ANY FILES, NO pictures, No downloads, NOTHING
Basically, my INTERNAL and my EXTERNAL are fully wiped.
with easeUS data recovery I can see all my files and maps on the external, BUT almost all of them are corrupted.
I can not recover them/ preview them.
I have not tried the internal memory yet. It is now doing a DEEP SCAN on the EXTERNAL card, connected to my PC via a SD Card Adapter.
Any possibilities to save something from the external and the internal memory ?
Everything else works normally.
My apps work, my contacts are ok.
PC is set to show hidden and system files => nothing to see
Recycle been on the phone is empty
used some recovery apps from the play store => nothing
Many thanks in advance.
PS: I have already done a search, also on google. But could not find anything useful.
Try Deleter.
I run easeUS recovery all night on the external memory.
Got back 5% of my pictures.
Most ara corrupted.
Same story for the internal memory.
Other suggestions, tips are welcome.
If the data was deleted corrupted then it might be restored corrupted.
I suggest, from now on, to upload your photos Google's servers with the Google Photos app.
You have unlimited storage for photos up to a certain quality.
Yep, i have installed google drive.
Sh#t has happened
Will try to use some other applications for recovery.
Had some pictures i needed.
Any names of really good software to recover sd card of internal memory ?
I told you, if the data was wiped in a corrupted state, then it will be restored in a corrupted stated. Because that's how it was the last time before it was deleted. It's like a checkpoint in a game. If you die, you will revive at the checkpoint in the same state you were when you reached that checkpoint.
You could give Deleter a try. But it won't magically repair corrupted data.
Try a program called recuva: https://www.piriform.com/recuva

I won't recommend it. It failed to recover two videos from my SD card that I needed to recover for investigation purposes, even when status of these files were Excellent. After restored, these files were corrupted. The same thing went on my .OGG file that was deleted accidentally by dBpoweramp before Vorbis Comments ID Tag was applied.
Even my friend said that Recuva was unable to recover her deleted photos as it should be. Yeah, the same thing, corrupted.

I have used recuva many times but, as with any software, it really depends on the state of the data at the time the software is run.
When one is desparate to recover files, I recommend trying as many programs as possible.
Hey guys.
Today i will try many different software.
I am trying to find a way to mount my internal storage as a drive with a driveLetter, so i can scan it.
Now its mte/umte or something like that.
So it has no driveletter.
Hey guys.
I managed to retrieve some pictures from the sd card.
Software i used.

EAsuse
Foenix recovery
For the internal memory.
Digdeeper
And some other ones on play store.
Just search for " photo recovey".
Maybe someone can use the names, if they get in the same situation as me.
Thx for the tips guys!

Installed apps all goes to Portable storage and some failed to run.

Hi everyone, I just updated my mcu (provided by the seller) and it wipe out all of my apps and setting. I re-downloaded the apps but some was failed to run. After the update I noticed there's portable storage on my system even though I did not hook up any sd card/usb on it. The reason for some apps failed to run is because every downloaded apps all goes straight into the portable storage instead of the internal ones. Appreciated if any of you could help me find a solution for this issue as the seller is hopeless.
Thank you in advance.

Samsung J7 Prime crashes after moving apps to SD card

I moved Acrobat Reader app to SD card and my phone started crashing and restarting suddenly.
I had to uninstall the app to prevent that.
Any time i reinstalled the app, I had to uninstall it, because it kept restarting.
Tried with other apps that could be moved to the SD card, and the same happened.
I include logcat output as attachment.
Even if I install some app that can't be moved to SD card, (like I did at 13:54 in the log) my phone restarts until I uninstall it.
Tried reinstalling (clearing data and updating) Google Play Store and Google Play services, and nothing.
Even my phone suddenly crashes without doing none of the above, without any crashing app installed (like it did at 18:41 in log).
My questions are:
1) How to solve it?
2) Isn't moving apps to the SD card supported?
3) If factory reset is the only solution, then there is some way to automate it with script?
I have all my settings documented, but doing it manually is so annoying. Even if I do now, i would like the possibility of scripting or backuping them for the next time.
I factory reset, and sudden restarts were gone few days.
But today my phone suddenly restarted and I got a new error.
I attach logcat output.
