PROBLEM SOLVED. PLEASE IGNORE THREAD.
I tried flashing a custom ROM using recovery.
After installing the zip files for CM7.1 and the GApps, I selected boot now.
After that, the device just wouldn't boot up. It's been on the bootscreen for over 20 minutes now and nothing's happening. I must have done something wrong.
It's not even being detected in RSD Lite in my PC so I can't SBF.
After googling some. I found out how to boot it to recovery. All I had to do was press Up Arrow + Power. I was pressing X + Power so it was not helping at first.
Lessons learned. Please ignore this post now. Sorry.
