Problems with HTC Apache

[Doltz]

Hi Everyone...
I'm new here at PPC Geeks and to PPCs in general.
I recently received an HTC Apache from one of my friends. When I got it, it would boot into a ridiculously corrupted version of WM6 (white screen in behind, icons only appeared when the corresponding button was pressed, took 15 minutes to actually boot). He told me he thought the problem was a bad bootloader, so i followed the directions for a stuck 2.04/2.05 bootloader, as he said that should fix it. I did notice before this that the bootloader screen did say 2.02, but he said it was not properly loaded.
So after I followed the directions for the Bell 2.04/2.05 bootloader, i could no longer even get into the corrupted WM6... it only goes to the bootloader screen. Even after 5 or 6 hard resets it still wont leave the bootloader. I tired flashing the ROM using Build OS, but everytime I do im getting a 100 Error. I have tried multiple USB ports on both a Vista and XP computer, the Vista computer running Bitdefender Gamesafe and the XP computer running Online Armor and Avira.
So can anyone help me or have i bricked it...
