Pesistant 'can't make scrrenshots' 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
