[Marcelo909]

hi. i need help. my phone was slow, i reset it and then i loaded the back up. i went to look at the firmware and it says its 6.1.a.2.55 but the phone works like a 6.1.a.2.45. I tried to update it but it says i alredy have the last version. How can i do to fix it?

If your phone is slow it might be one or more apps you've installed that's causing the problem. Try to reset the phone or repair the software using PC Companion and see how it performs before you restore any backup or apps.
