I have an HTC desire 616, bootloader locked, S-ON. I am able to enter on recovery-mode but the device is not listed in ADB, though I have all latest drivers from Google, Windows and HTC. I am able to enter in sideload mode, drivers are working and I have 3 choices and 3 installed but the signature check prevents me to install any sort of updates.
I think is still on the software and relies on drivers but I don't know what I can do further
Is it possible to flash a unlock_code.bin of zeros?
Kindly waiting your help
