HELP: Windows Mobile 6.1 install...

[weirdcomputernerd]

Hello All!
Im a complete noob, and accidentally (i dont know how) deleted the windows mobile 5 OS off my HTC Apache. Pretty much it wont start up =(.

What i want is a way of installing Windows Mobile 6.1. I need a straight forward tutorial, with ALL THE FILES ATTACHED because all the tutorials i go to have expired links to the files and it BUGS THE HECK OUT OF ME!
So please help, i want to connect it to the telecom NZ network (if that helps)...

... any querys, please ask (and say how to find the information if possible (like i said: im a COMPLETE noob at this sorta stuff))

Also: i have the buildOS thing install on my computer, and im running vista....

(Thanks in advance for you help)

p.s. im going away in like 4 days (end of december) so if i dont reply... you know why....
