How To unlock and flash with Video Walk Through!

[slave13]

hi i feel like i have try every rom for my verizon htc touch pro that i can get my hands on and for some reason every time it just gives me the update error and i just today went to to the newest normal verizon rom and it still seems to do the same thing and its driving me nuts because i would like to go to wm 6.5 on my htc touch pro i think the most recent number mentioned on the error update is 262 can anyone tell me what is here and why is not let me go to custom roms what it basically does is it does everything upto the part where it would start updating to the new rom and then it stops responding or something it just stays at 0% and then after a bit give me the whole error update thing i was thinking something since i knownest that the unlock screen on my mine is Raphael 500 and not 800 like on some other screen shoots of other peoples flash things does that make a difference if so where can i get the rom to go to 800.
