Hello, I have downloaded the said update, (12.5.8.0 RKBCNXM) Stable but, it will not update? The button to install is highlighted but will not "press?"
Any clue please?
It's the first twrp. Download it manually, the twrp image from the main thread. Boot into fastboot mode and type the command into the cmd... Something like fastboot boot twrpname.img
Switch to your language it's the third on the left side then click the globe.
Go to install and select the manually downloaded zip which must be still on your phone you have downloaded with... Now slide to install and reboot.. .
