I own an HTC One S and I've had it for about a year now. I recently rooted it about 3 or 4 days ago and everything was going smoothly, I pushed Superuser.zip onto the SD card and it worked fine, then I figured I might as well install a ROM manager so I got one off the Play Store, then I downloaded Clockworkmod Recovery and when I booted into recovery to flash it, the phone screen went dark, and wouldn't turn on. When I plugged the phone into the charger, the LED came on and stayed on even if I disconnected the phone. If I hold the power button, the screen flashes very quickly, the LED goes off and about 10 seconds later, the LED comes back on and it's back to the black screen. I had the same problem earlier but I pressed a combination of buttons (I don't remember which ones) and the screen came on so it's not bricked badly, I need help urgently.
Thank you in advance.
