I am running an unlocked verizon storm 1 on v4.7.0.148. on Att. I would like to upgrade the OS. I have 2 questions. Can I click on the option on the phone to update the OS since I dont have verizon. And after I do upgrade my OS do I have to re-install the att service packs? Thanks for your help.
The first question is no. Find verizon official os 5.0.0 328 or leak 5.0.0.419 version and install it using desktop manager or bbsak. There should be a thread on top of topic on how to do it. The second question I think you do have to resend the ATT service book after os upgrade. There is also a thread about that. Try searching for it
