So in this thread which I started earlier today,
http://forum.ppcgeeks.com/showthread.php?t=51416 , I acted without enough research, with my friend assuring me it would be fine. I attempted to update the rom on my Alltel 6800, which is/was flashed over to cricket, with the blackpill rom. It went through the whole update completely fine, and the phone reset, but it wouldn't go past the Alltel splash screen.
Then, trying to fix this, my friend said it was likely the rom, so we tried 2 or 3 other roms, wouldn't work. They would go through the update to 100 percent, but it would lock at the Alltel screen. Then we attempted to install a WM6 rom that we found for the alltel phone, and now I can't do anything on my phone.
My phone is now stuck on the boot loader.
EDIT: I got out of bootloader screen after attemting the titan bootloader exit tool on my computer, rather than my friends. I don't think I bricked my phone after all, but I don't have high hopes at this point either.
Any help would be appreciated.
