Instead of it booting properly, it goes to the htc splash (With the red text at the bottom, but it isn't entering recovery mode) and after that, it goes to a black screen. After a couple of minutes, it simply loops back to the splash.
What I was trying to do was use RUU, but of course, i was s-on and attempts to s-off the device failed. So I used htc1guru's RUU exe (I think I downloaded the wrong file, wasnt supposed to use the exe, but flash a stock rom. I know, I know, I'm stupid, don't really remember what i was thinking.) and now the device is stuck like this. I tried adb devices to try and see if it could still connect to the computer, but nothing came up. Doing the light trick either doesn't help a whole lot.
Any ideas what to do?
EDIT: successfully flashed a reset. Had to hold power, vol up + down buttons, wait for it to turn off and quickly hold power and vol down. I then flashed the guru reset Rom and I am now at stock.
