Help [Resolved] Accidentally set radio to USA band on Nexus 6

[jordan_isk00l]

Hiya,
I really messed up. I wasn't getting a 4G signal, and someone reccomended I go into a menu that you can access through the phone by dialing *#*#4646#*#*. I did that, and I accidentally set my radio band to USA band. I can't change it back and I can't get a signal. I need to change it back to whatever band the UK uses for mobile networks

I'm not rooted, and I don't really want to - but if anyone can help me, I'd really appreciate it!

Thanks!

Do you know what your band should be for your carrier?

If it comes down to it, reflashing the factory image should get you all worked out. On the downside - It will completely wipe your data.

A simple factory reset might not work since all it does is wipe the /data cache. I'm not sure where the changes you made are stored.

Hiya, I tried factory resetting twice, no luck... would flashing the factory image require rooting? Thanks!

To be completely honest, I'm not sure - I'm on Giffgaff though. Sorry!

You don't need to root to flash the stock firmware, but you will need the fastboot tools from the Android SDK.

Is Giffgaff an O2 reseller?

No, it just runs on their network - I bought the phone from Carphone Warehouse though. Thanks for your help!

The bootloader is unlocked during the process, but root is not required and the bootloader can be re-locked at anytime after.

Thanks! I'm trying this now, i'll update in about 30 mins

Yep! Flashing the stock firmware did it! It's all back to normal now. Thank you all so much for your help!

Glad that worked! Thanks for letting us know .

If you want to re-lock the bootloader, the command from fastboot should be "fastboot oem lock"
