Just a friendly suggestion: It would be very helpful if there was an user editable list of devices somewhere, where you could see what works and what doesn't with what version.
ofcourse no...bootloader doesn't unlock, no developing for this device unfortunately
Why is that necessary? I thought that the point of unlocking the bootloader was to make it possible to install a recovery?
Is the recovery installed in this...
It should work in this way
In earlier versions, if you pressed the plus button for chrome, you got two chrome instances side by side.
Now, it makes the existing instance floating.
But if this is the way you want it to act, that's fine...
I have that on my investigation list, but with very very low priority.
Reason is: There is the screen filter app that allows you to achieve the same as well. So, no big pressure for me to focus on it.
Thanks for the recommendation
I used MiniTool partition wizard to create a second ext4 partition on the SD card from windows. The second partition must come last.
Then you transfer your /data/ folder to that partition (Or don't and start fresh), and then flash:
