| | Re: Help needed to upgrade OS on 9530
You can install any OS you wish, as long as it is for your specific device, the 9530. See the sticky at the top of the 9500 section for the OS and instructions. Make sure that you have a good back up first.
As for the signal issue, I doubt and OS update will fix it. Can you do every thing you need to do with the phone as it is now - email, surf, text, make and receive calls, etc?
