Worked for me too, thanks a lot.
After trying to upgrade firmware (downloaded from the SJCAM Website), my SJ4000 couldnt turn on (boot music, blue light but screen off).
Perfect with the firmware linked below
Important to note that ive got a SJ4000 with no SJCAM Logo, like Sandyman tI hought it was a fake (purchased from DX). So 2 good news, its not a fake on, and my camera is working again !
