I got an old phone, HTC WildFire S, which works perfectly expect one thing, the power button has gone bad. Can I start my phone from computer using USB connection somehow?
When your phone is not turned on it can't have a adb service running (Disregarding the possible technical difficulties it would also be a security issue.)
Try the following instead:
- Take out your battery and connect the phone to a charger
- Your phone should now turn on.
- Insert your battery.
- Hold power button (+).
Your device should boot now. I'm not sure if this will work for you but i booted my old ZTE Blade using these steps.
