Hey jose, I have a C800 with the exact same specifications as your phone that you ugraded. I tried upgrading it to WM6 with your given instructions and download links.
Now my phone is dead duting the step 4 you mentioned : i cannot even flash the RUU <mentioned in your google search reference>. I get Error 300 which means that I am not flashing the right RUU for my model.
PLEASE help me/guide me to a link which has a usable RUU for my phone.
All the recovery methods I can find on the site are for IPL/SPLs beyond 4.000.000
Please help me to upgrade my phone - or atleast restore it to its previous status and save it.
