Ok, so i tried updating via SUS but it was fussy and wouldnt let me cos i've got an unlocked bootloadeer, it did however download the files into its temp folder which i have re-hashed into a ftf.
So far i've only booted my phone and it seems to be working fine. It was fussy about connecting to my network for a few minutes but worked after searching and it made a call ok
Dont come back to me with problems, i have never done this before and just followed a tutorial to make the ftf
