so I've been trying to update my galaxy S3 (T-Mobile) SGH-T999 to KitKat4.4 and after following a bunch of tutorials, I just installed CWM 126.96.36.199 Advance Edition on my phone. I used ODIN 3.09 to install philz_touch_6.12.8-i9500.tar.md5 (I know my phone is not a i9500, but one of the tutorials lead me to this file, could that be the problem?), followed all the instructions but now my phone won't go into recovery mode anymore.
Before all this I also rooted my phone (I used KingRoot) and tried ROM Manager, but after this didn't work I read that I needed to get the CWM 188.8.131.52 Advance Edition.
Anyone any idea what's going on or how I can fix this?
EDIT: Just to describe what I mean by"won't go in recovery mode": When I press volume up, home and power button I get the SAMSUNG recovery screen, and then I let go of the power button and then nothing happens, black screen, phone is basically turned off. It turns on fine, but I just can't reach the recovery mode.
