Well I managed to lock my bootloader and that, but when i tried to install the RUU it gave me a error. I think it might be an older version.
I think I'm going to need the 2.00.771.3 version :S
I think my phone is useless now. A bit of info, I tried factory resetting my phone (I have rooted my phone prior to this and stupidly thought that factory reset would get rid of the root) but when I reset my phone after the inital setup had gone through all menus it said setup has stopped working. Then my phone wouldn't work no apps or home screen, I could recieve calls and then go onto my settings at the top but nothing more then that, I'm not sure how I can get my phone working again now lol
