[Solved] Pesistant 'can't make screenshots' lollipop storage access problem? - Android Q&A, Help & Troubleshooting

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

Stuck with CWM, Using adb to push.

Previously I have used adb to push files onto my internal sdcard, to then flash the phone.
In these instances I've pushed to /data/media, loaded up CWM, choose zip from internal. File is there, flash.
All very easy.
This time around, Ive run Super Wipe, pushed the new rom to /data/media.
But when i go to 'choose zip from internal sdcard', I get 'Couldn't open directory', 'No files found'
I even tested before I wiped, and pushing to /data/media worked, and they were found in CWM afterwards at root.
Any ideas? I dont have an external sdcard right now annoyingly, so adb pushing is my only idea Ive had.
It seems to not pick up its own root directory; always saying 'couldn't open directory', with or without data being mounted.
Cheers in advance! Soft brick for now, ouch
EDIT: Internal SDcard isn't being mounted when using the phone. Im running stock firmware, and I cant even install apps because they cant create folders. Messaging doesn't work, becuase it cant save the messages. Its like the internal sdcard has disconnected from the phone...
When hooked up to the PC, the phone storage is blank, and when I try to put files into it, it stays on 0%
My internal storage is non-responsive.

[Q] How to copy SD files from TWRP or fastboot to desktop

Hi guys,
I need your guys' help. Somehow I messed up my installation (Play store crashing, can't see SD card directory in the files browser etc.).
Goal:
All I want to do right now is to copy my SD card files from my N5 to my desktop (Mac) so I have all the settings and backups and then wipe the whole phone and start fresh, subsequently restoring app and settings.
I can see my SD card directory within the TWRP file manager, also my Nandroid backup, which I tried restoring (I don't know if you have to wipe anything before doing so), but after well over an hour turned the device off.
I read somewhere that there is a pull function to copy files from phone to desktop (see here: http://stackoverflow.com/questions/17629889/android-adb-pull-file-on-desktop). So I tried adb pull sdcard/ /Users/myusername/Desktop/android but it says "command not found"
Question:
What am I doing wrong and how do I copy the important stuff over?
Note: I have a N5 with TWRP custom recovery, unlocked bootloader.

Lenovo s860 custom rom help.

hello.
Im trying to install custom rom on lenovo s860.
Everywhere everything says that put .zip on the sd card. I can flash stock rom with sp tool but the stock is chinese hell with all the crap UI and lenovo apps that cannot be unstalled.
Trying to install whole custom ROM.
(i've flashed many roms before with success)
I have twrp installed and everything. BUT this phone does not have sd card slot.
When I put the .zip into build in storage the twrp cannot find it anywhere.
Also I dont know if this is bug but twrp says "internal storage (0MB)"
Also I cannot backup stock rom, it says mount failed and thats it
edit #2, I have rooted stock rom, if I move .zip file to root or to any folder or anywhere. it just disapears after I reboot my phone, so even If I move the file into root and the reboot to twrp the .zip is gone
edit #3 I cannot access adb, I cant push files,
twrp says unable to moust /system, /sdcard /internal storage and all of that stuff.
I have googeled the whole fooking google and cannot find anything that helps

Internal Storage Empty? ROM Installation

I'm hoping to get something clarified when it comes to installing ROMs. My phone was working fine for a couple of months since I acquired it, I started getting a bootloop yesterday, and I decided to use TWRP to do a factory reset. Still bootloop. I did another factory reset + wiped out internal storage, and reinstalled the ROM. Checked file manager in TWRP, and saw that internal storage is still empty, with the exception of the TWRP folder, and the ROM zip I transferred back on using my laptop.
I tried booting up anyway, and still have a boot loop.
Is it normal for a successful ROM flash to have an empty internal drive? Are the folders Android, data, DCIM, and the rest all populated on the internal drive upon successful bootup? Or is it something that's supposed to be there right after a successful ROM flash?
I'm having a had time figuring out what I need to do at this point.

Problem installing magisk-cant access internal memory from twrp

Hi all, I need a little help, I've unlocked bootloader and installed twrp recovery (that's wiped data on the phone and I've reinstalled apps and accounts).
The guide i was following ask to reboot and boot twrp recovery (working) and to install magisk zip file copied from PC to internal memory
I copied magisk in internal memory (root and download folders) but in TWRP I can't see the storage i get from PC, only different folders.
I tried also adb sideload D:\Android\Magisk-v21.2.zip directly from PC but i get errors on mounted file systems yrying to install files i think, I tried to check and mount file systems in TWRP advanced options but I can't mount them ...
How can I install Magisk ?
Thanks for help

I don't have a temp folder, only Alarms, Android, DCIM...., Ringtones and Whatsup folders, should I create it ? Then i can see it in twrp ?
By the way upgraded twrp to 3.4.0.2
Tried to create temp but I can't see It obvously in twrp as the rest of the folders, only mounted filesystem is metadata
go in twrp to advanced wipe --> format data partition to ext2 --> wait --> when done format back to ext4 --> wait --> now see if your OS recognizes the USB android device. try usb replugging if not --> now you should see a new partion where you can write in your file explorer on HOST OS.

Ok since It is wiping data partition and I'm under mobile connection I'll do this in the next couple of days back home. Just to confirm, I can see internal memory partition from host OS without problems, I can copy files from OS to mobile. The problem is that rebboting in recovery TWRP I can't see FROM MOBILE that partition and folders, so I can't access magisk file I copied ...
With your suggestion do you mean that the new formatted partition is visible both in TWRP and OS ?

I found many and they are all similar...
- Unlock boot loader
- Install recovery TWRP
- Reboot in recovery (sometimes from phone other guides from image on PC)
- install magisk copied from OS from twrp recovery
Everything is clear except for I can't access the data partition from TWRP in the last step so I can't see the copied magisk file and I can't mount the partitions in TWRP (i get an error)
A couple of guides:
Root OnePlus 7T Pro (hotdog) and Install TWRP Recovery 3.4.0 (androidweblog.com)
Download Latest Magisk zip 21.2 and Magisk Manager 8.0.4 and Root your phone (getdroidtips.com)
In the second one they use the sdcard partition but I don't have sdcard on 7T Pro ...
You can point me to a different method if available to get magisk installed ...
Thanks for the help

so when you do as i said you are in twrp cos you booted to it. twrp will read and be able to access your phones storage. you are not wiping the data partion but are formating it to ext2 and then back to ext4 (still do backup as data will be lost). this enables twrp to circumvent the oxygen decryption / format. NOW and only AFTER THAT dont reboot (dont), but now your HOST can copy the desired magisk to the phone that is still in twrp RECOVERY MODE. Thus you can now install it with twrp since twrp can now access and read the recently copied image. anyways i wont do it. i used a patched magisk image. was the only thing that ultimately worked for a clean rooting and it didnt even unlock the /system_boot and /vendor partions but it works. find in the oneplus 7t pro guideds forum topic your corresponding magisk image and flash it to disk with fastboot flash boot magisk-patched.img. that worked pretty well when you use the right android version 10.0.x.etc.
actually, wtf do i know. i just followed this thread:
[Guide] How to Root OnePlus 7T Pro with TWRP
thanks for this detailed root process, I've been looking for this for around 3days. (my OP7t pro is coming today will try this root method)
forum.xda-developers.com
Clearly stated in the TWRP thread, decrypting OOS is not working. And I wouldn't even bother formating data.
In order to flash zip is TWRP you most execute;
"adb push magisk.zip /cache",
then in TWRP go into that folder and flash the file.
Or you can do patched image method, you can find guides in guides section.
Some basic researching would also help.

PERFECT thank you very much, got only a couple of warnings at the end:
failed to mount /system_root (permission denied)
failed to mount /vendor (permission denied)
But It seems correct.
I will check for patched image to better understand what is tha advantage compared to the standard one.

Those errors are nothing to worry about since it's not possible to modify those partitions on stock.
