How to revert radio band back to default?

Francis_RN — Mon, 13 Jul 2015 22:35:10 GMT

Hi guys! I just got my Z3(D6653) a week ago. As i was exploring my phone, i bumped into the "testing" setting by dialing *#*#4636#*#*. I went into phone info tapped the menu icon on upper right corner and "accidentally" selected USA band then poof! There goes my signal, gone! I'm from Philippines and my provider is Globe telecom. So, how will i revert back my radio band? I tried searching and didn't find any answer. It was so depressing i want to kill myself for it. Hope you guys can help me before something bad happens. Lol! Thank you guys! Good day

@Francis_RN

You can't change the bands, perhaps you rooted and/or unlocked the bootloader and did something else?

Try repairing your phone with Sony PC Companion.

I didn't unlocked bootloader, my phone is not rooted. Just opened the service settings by dialing *#*#4636#*#*. I tried repairing using pc companion but it didn't work. I tried 1bit's advice and it did work. I got my signal back. Problem solved! Thanks guys!

By downloading an app called hidden settings\you see an icon which calls select band mode you can manually change it
