@Balrong It is possible to install a click by browsing the web site open-store.io, download it and install from there. yes the install is an option as advised by @mrt10001. I have found no other way to install again with UT already installed than running 'sudo reboot bootloader' and launching the installer from there (after connecting the USB cable of course).

im like 50% backwards engineering skyrim and fallout 4 game engine to run native on UT with a less hard time

but you would need to post the logs file

@MadDino Check here. Download the unlock.rar file (link still works). You don't need to root the device for UT. Follow these instructions and you need a Windows PC: *DATA WILL BE WIPED SO MAKE A BACKUP Download this zip(you already have) and you'll get 2 folders 'unlock' and drivers https://drive.google.com/open?id=1YpezCedaRWGDS9WW7UaXXyyBod0Bk5qp Install the drivers and go the 'unlock' folder Reboot your phone to fastboot mode by pressing volume up + power on at the same time. Connect it to pc and open unlock.bat in 'unlock' folder Done*

update i forgot to post the links

Update: I've just noticed that the signal strength indicator works only during a call but there is no function once a call is terminated.

@peat_psuwit I installed it, don't see the problem about update channel not displayed. It may have been a fluke.
