Or you can install Kernel Auditor, and look in the settings menu where you can find options for copying the logs to the internal storage.
I am wondering how you can even open the device. Can you please describe the steps you have done when installing the ROM? The log is full of errors and exceptions party related to encryption (applications using an outdated mechanism to derive the keys) but also related to usbmanager and mtp service.
I suggest you to set up the device newly following the installation instructions in the OP. Do a full wipe and do *not* restore any app / data using e.g. Titanium or something else.

@danja95 that's strange because in the log I saw initialization of several laucher applications. From where do they come if they are not installed? Did you wipe data, too? Otherwise you will keep the apps previously installed. Another thing which might cause the issues: if you install SuperSU not in systemless mode you run into issues. Try to skip the SuperSU installation or use Magisk 15.3 which always installs systemless and provides SuperSU functionality, too.
The USB-Hub could cause the issues with mtp and usb so probably it would be better to remove the hub , at least until everything is set up correctly.
I used this app https://play.google.com/store/apps/details?id=org.crape.rotationcontrol to get my launcher rotating. Maybe it helps for the lock screen, too.
Quite simple. Just flash the microG version provided in post #2. Then head over to the microG download section and install the corresponding apps from there. From my point of view it makes sense to install all provided apps beside Fake Store (you can install Aurora Store directly from F-Droid, for example). Reboot your device afterwards, then open microG Settings app and set it up. That's it.
Make sure you enabled developer settings. If you already did that,connect your tablet to PC and go in to developer settings, find "Select USB Configuration" and change it to MTP.Hello and thank you for your Work!
How can i get my USB File Transfer working after Update on my Nexus7 Wifi 2012 ?
I can select "File transfer only" wen plug in USB Cable, but it does not work on my Win7 Computer.
I allways need to restart the Device in Recovery Mode to upload Files to the Tablet.
It also did not work in my Drohne App, wen i plug in USB i got asked if i want to allow, i press Yes but there is no Video Stream sending over USB File Transfer.
To explain a bit more, i connect my Tablet with the Drohne over App and USB Cable to remote Controller.
Normaly the App get the live Video stream from the Drohne Remote Controller over USB.
After updating Firmware this is not working anymore. I think there is something wrong with the USB File transfer system, as i also are no longer able to send Files from my Computer without restarting the Tablet to Recovery Mode.
Only in Recovery Mode File transfer over USB works fine.
So im in hope some of you understand my problem and maybe have a solution ?
As my Tablet was never so fast before, as it is now after the Update and i want to keep this Firmware
thank you and stay healthy!
