as always thanx XDA forum

Rooting "might" void your warranty. I'm not responsible if anything happen to your phone (nothing should go wrong,, if something do go wrong, just repeat the whole process).

you need to unzip the file

on service menu check the bootloader if it says unlock yes it's not branded to a network

I try to use the SUS and display a error message:

i dont understand why say that. i have only app from google play.

[Uliwooly]

you need to relock your bootloader otherwise you can't use SUS nor PCC

I wasn't aware you could do this till I read this thread. Worked perfectly - I used the same method to re flash an Arc S with a generic fw too.

Thank you
