Default MDK but won't boot aosp

Ok, I got this phone with MDK bootloader, CWM, and cm10.2 on it. Had to go to TW and flashed hyper drive with kt kernel to enable diag mode to flash to page plus, and then I attempted to flash a handful of aosp roms and all of them wouldn't boot, said non factory samsung firmware, so..... Rebooted recovery and restored tw, will I not be able to enjoy aosp ever again now? :'(
