I just flashed the WM5 Alltel ROM and it gave me Error 270, saying the ROM is corrupt and to check the update utility... I exited bootloader via the Titan exit bootloader utility and soft reset the phone and it works... but ceipui.exe can not be executed.
I'm going to try the TNZ ROM and see if it works but I'm just curious if anyone has gotten this to work. I'll keep tweaking as I always do
