Help I wanna go back to 4G

[javamann]

My battery was not behaving and to solve the problem I stopped various services to find the culprit. One of these was stopping the 3g/4g searching. Well that was not the culprit. It was my weak WIFI signal at home which resulted in a constant WIFI on and off (a hint for those with a similar problem). Now I want to go back to 4g and I forgot how I had done it originally. Will somebody help a forgetful old man to get back his 4G on the phone he loves.

To help you undo everything you did, we'd need to know everything you did. It might be easier just to do a factory reset?

pop the sim, then enter *#2263# and set it to Automatic. Then reboot (and obviously re-seat the sim)

I don't want to undo everything. And If I remembered what I did then I'd know how to undo, wouldn't I?

And here's a link to a list of *# commands so people know what they're doing to their phones...

Not to thread jack but I forgot a similar code that I was using to increase how long my phone rang before going to voicemail, anyone have any ideas?
