I tried the holding of the volume button ad putting the usb in, but it does not work on my device. is there any other way to turn it on?
Hello. Try next steps (apologize for my english, i’m spanish :) ) Hold Volume down and home at same time. Then, plug in the usb cable, previously connected to computer. The device must go to download mode. Then, unpush both buttons, and press volume down to cancel and restar the device. Worked for me in Galaxy trend, Galaxy S2 and BQ. Good luck. Please, tell me if worked.
What does it do when you plug it in to charge? A lot of times, plugging it in, turns the device on.
The volume down n home button trick works very fine. Thank you very much
