My device can still be turned on by pressing the power button a little longer.įinally I took the initiative to root with magisk. for navigation using the volume up and down buttons. then I press volume down, it works, and my device displays the choice again 1.

until here my volume up button doesn't work at all. But another problem arises, when I type 'fastboot oem unlock', my device displays to open Bootloader press volume up, if you don't want to open it press volume down. then I tried to open it via ADB fastboot. I think maybe my device is locked Bootloader. I flash via ADB fastboot with a command prompt via PC. Then I got an alternative to using another device TWRP.

However, TWRP files for my device type are very difficult to find. I have tried rooting by applications like Kingroot, Kingoroot and others, but all failed.

I have a android with the Lenovo A6600d40 brand with a build number A6600d40_S235_170405_ROW. And do not forget to say thank you for helping me in solving the problem I faced. First of all I want to apologize if my English is very bad.
