Cant load ROMS
 

i just bought a xv6700 off ebay refurbished. its stuck in bootlaoder mode and when i used this tutorial http://forum.ppcgeeks.com/showthread.php?t=33076 to get out, i got to the last part, i ran the utility on and it told me the ROM wasnt made for my phone(this also happened when i tried to put helmi_c's wm6 on it). how do i upload new ROMS if my phone isnt what i think it is. sorry im new to this and dont really know what im talking about. and help would be appreciated.
