Sorry I meant instructions for flashing the ROM. Never done it before.
I have flashed ROMS before on my TP2 and it is always
USE AT YOUR OWN RISK. I have never flashed my Arrive and I did about a good 2 hours of reading before I started. I am also a developer so that helped as well. That being said once I understood directions it was a straightforward process.
The ROM i used was
[ROM] HTC 7 Pro 7.8 & HTC Arrive 7.8 Sianto Edition AL [ROM] HTC 7 Pro 7.8 & HTC Arrive 7.8 Sianto Edition AL - xda-developers
But I started reading the entire
HTC 7 Pro 7.8 & HTC Arrive catagory.
I also read this thread fully before attempting anything
HTC Arrive Hacking Guide - xda-developers.
Once again it is use at your own risk but I found the process to be extremely easy. Once done the phone started off in factory reset mode, I changed my country, location, language, changed my accent, installed my apps everything is working fine except xbox tile no longer live(not a biggie for me), couple of apps have different icons or tiles, and when searching in BING for an address it does not pull up the maps with the correct information as often anymore, but I HAVE NOKIA maps/drive so its a good tradeoff
