internal storage disappeared - Android Q&A, Help & Troubleshooting

i restarted my lg g3 d855 which uses 7.1.2 lineage stock to twrp and did a dalvik and a cache wipe.
when i opened up my phone spotify gave me a no storage error, i tried to see what's wrong by using es file explorer pro and and the stock file explorer, both had nothing but an empty sign.
i rebooted to twrp again and it's own file explorer built in under the advanced menu, i was able to see /sdcard and /storage/emulated/0 and files under these partitions such ad Android and downloads.
what should i do? i can't even take screenshots because none of the apps have access to internal storage

[Q] Internal data problem

My Nexus 7 device. Flashed PA 3.0 using TWRP. I used a backup to restore the previous rom. Made some Titanium backups. Reflashed PA 3.0 and Gapps.
THe data kept for user access under sdcard disappeared. Seems like it was erased and replaced with a fresh set of new folders and little bit of data that PA just made. Checked storage space and about the same amount of data/memory is still used up on sdcard. Checked around the directories below sdcard using file expert and couldnt find it. Used TWRP to look around the directories and found all my data in /data/media
Tried to move it to /sdcard but it fails.
Tried to move it in file expert but only a few files s moved. File expert doesnt seem to recognize any of the files in /data/media as having any data, ie there is 0 bytes on each file and all folders become a 0byte file and not a folder.
I can still see the old data i want but how do i retrieve it safely?

[Q] Missing files in TWRP but shows in ES File Explorer

ok here it goes.
I flashed a 4.2.2 rom after backing up CleanRom. the rom was broken so I wiped everything and restored my cleanrom backup.
now In ES file explorer shows all my SDCARD stuff in /sdcard/0
so i copied everything into /sdcard
now in TWRP, My /sdcard location shows a couple folders but my stuff isnt there. but when I boot back into the system, its all there in ES file explorer.
with android 4.2.2, twrp will recognize your files in data/media. I noticed this when trying to restore a backup.
I have the same issue, only it involves my TWRP backups. I can see them in the file explorer in recovery, but when I got to restore, they're not there. I'm running stock 1.26.502.12 with Android 4.1.2. Needless to say I'm pretty annoyed....
So what i just did was transferred all the files i wanted over to my comp, wiped the sd partition then transferred back. TWRP saw my backups immediately. Try that to see if it helps.

[Solved] Pesistant 'can't make screenshots' lollipop storage access problem?

Hallo,
Mobile: Huawei G8, currently stock ROM Austria RIO-L01C150B130
What works:
Booting Android, Installing apps, change seettings, viewing internal storage with es file explorer
What does not work
Making screenshots, making OTA (error message when trying to download dat), viewing internal storage with Astro
History: Start condition: Phone has run Lollipop, been unlocked, unrooted, TWRP installed. Phone has been encrypted
OTA downloaded Marshmallow update to SD, force closed all apps and rebooted
Mobile stuck in recovery (TWRP). TWRP could not access SD card. -Comment: It seems that the phone needs the stock recovery for OTA
Finally got TWRP accepting the SD card by formatting it with SD formatter tool but could not get anything work.
Wiped storage with TWRP (for clean install)
Flashed boot.img and recovery.img from Marshmallow RIO-L01C432B340CUSTC432D001. (all flashing done with fastboot). Tried to update system via dload folder. Update failed at 5% (right after checking files and starting update). Phone goes in endless boot loop.
Flashed system.img of Marshmallow above. Phone goes in endless boot loop.
Flashed revocery.img and boot.img of Lollipop version above.
Tried dload folder method. Fails immediately.
Flashed Lollipop system.img. Phone boots w/o asking for encryption key.
Wiped Cache with stock recovery.
All .img files where extracted from update.app with HuaweiUpdateExtractor with profile 'unkown (worstenbrood)'.
That's basically where I am. I hope I didn't forget something important.
Could be something easy like missing directories. Could be something tricky like partitioning or access right issues.
After about 16h fiddling around with the phone I can hardly thing clear anymore.
Any hints are highly welcome.
Regards
Chilli
It appears that the phone can't acces SDCard0. SDCard0 and many other directories show up as empty in ES File Explorer. I guess Astro tries to show the data directory or SDCard0 instead of root, which can't be accessed either (--> Astro shows nothing). Connected to PC via USB internal storage shows only two folders: Pictures and system. There is some preloaded content in these directrories, but no changes can be made.
The parition 'data' itself seems to be fine, because apps can be downloaded and updated (folder 'app' is working correctly). So it seems to be some access problem of specific directories of the partition 'data'. Which is pretty strange.
I made a clean install of Marshmallow (that did not work) and a dirty flash of Lollipop.
Edit:
I swiped everything with TWRP exept external SD Card
I installed Lollipop and this time access rights are fine.
It can store screenshots, it can store OTA data.
OTA still fails. No clue why, but I guss that's another story.
Thanks

HELP! I accidentally changed my file system !!!

I was trying to fix the ''encryption unsuccessful'' problem, following the youtube video, he tells me to change the file system of System, Cache and Data. It didn't work for me so i went and explore by my own and accidentally changed the file system of something to something else...! Now my phone cannot detect my internal storage in TWRP as i see it shows my MicroSD card = 11mb, and folders like /sdcard/ is gone..
Sorry for being stupid..

Android 10 and Storage access

Hello
I recently upgraded to Android 10 and it seems like a lot of my apps have issues with storage permissions now. I've read they changed it to storage scopes but when I open some of my apps the first time I get prompt about it being built for an older version of Android, the app asks for storage access like it always did and I grant it but slot of the apps have issues writing to storage or reading other directories. If I go to settings there's storage permission which is enabled but that's it. How can I grant it more access so it can read things from my downloads folder or something? Even some like catlog if I give it root access it still does nothing.
Had an issue where system partition was not mounted after flashing twrp and magisk. After formatting my system partition, flashing lastest image, and then flashing magisk again system partition was mounted. Not sure what happened.
Have you rooted your device?
As for my stock system software, I can enable some app as 'trusted app'. So that it would have no issues about storage permissions.
