Thanks so far.
Sadly i'm having no luck with it at the moment.
As it stands the phone model is GT-i9100P, Orange branded and upgraded to ICS via Kies, which all seemed to go ok.
I've tried the wipes and just still get stuck on the reboot screen with the yellow triangle.
I'm thinking about installing a stock Orange update now but does this depend on the kernel also? Would like to just start all over again really
