4g disabled. - Android Q&A, Help & Troubleshooting

My us cellular gs3 4g won't work. I recently updated from cm10.1 nightly to cm10.1 RC5 When I noticed it didn't work. I then factory reset twice and cleared data and flashed hyperdrive rsl13. I have done the *228 to do a tower sync. When my phone was stock it also had problems connecting to 4g and they told me to do a fa tory reset and 228. It took a few days for it to randomly come back.
Here is a screenshot using samsung secret dialer codes.

try a factory reset in hboot, then reboot.
I'll try that and report back

I have data but not after the initial setup process. Any ideas?

Sorry if this sounds condescending, but is the back cover on the phone?
Edit: Never mind, you said no data, not no signal.
It was a bad SIM card.

Unable to text

Hi. I am unable to send any texts. After I applied dirtyracun successfully, I decided to start fresh and wipe the internal storage(first time I did that), factory reset and system. This is very discerning as I tried methods from Sprint forums and didn't work. I even flashed team Venom rom again to update prl and profile and still nothing.

EDIT: mysteriously solved
I just got this and all the sudden I can send again.... What the heck was that? This was immediately after restoring for the 3rd time from smsbackup+.

I have never used smsbackup+ never seen anything like it
Are you on an aosp ROM?
Sometimes i get something similar after flashing and i think its the phone reconnecting to sprints network.

This problem was fixed and I believe it was from a bad restore from the call/sms log backup app smsbackup+.

Reflash a sense rom, refresh prl and profile, wipe cache, dalvick, factory reset, and system. Then flash cm10.1 again and see if its better.
Also verify your md5 sum of the download.

I just reflashed the ROM and it worked. Sorry, that should have been the first thing I did

SOLVED: Having some data issues

So I got my S4 rooted, installed TWRP and downloaded Foxhound only to find out that it caused all my mobile data to stop working. So I went ahead and downloaded Synergy ROM, did a factory wipe, installed and now I get data but I have lost 4G. Any idea as to why this is happening? Thanks
