[Q] 3G not connecting? - Epic 4G Q&A, Help & Troubleshooting

I did not have this problem the day before, but for some reason my 3g wont connect.
I haven't added anything else to my phone since the last time I used 3G. 4G works fine.
And yes I tried odin to complete stock. All I get is an error 67 message and no 3G going back to stock.
Is there any solution?
I'm on DI18 rooted.

It's weird because today my 3g is barely working.

have you tried updating your PRL?

4g Data wont connect after PRL update

I'm relatively new to andriod OS, but have been able to root my EVO without a hitch. I updated my radio (and firmware) to lastest builds(after the PRL update), but I'm unable to pull a connection using 4g. I'm able to use 3g like normal, but upon connecting to 4g, I cannot use any data unless it drops back to 3g. Any suggestions/

Which rom are you on? When you dial *2 do you get to Sprint or some other carrier? I think this screwed up my 4g as well. Flash the RUU go back to stock and start over. Then don't upgrade your PRL at all until someone starts posting them with a way to upgrade manually

[Q]4G Connection problem after update

Guys, having a serious problem here to connect 4g network. I m working at Dallas, TX, where 4g network is available. Here is what happened.
I flashed the latest radio updates, 2.15.00.09.01 (not combination version, just radio), then I used HBoot way to update PRI to 1.77_003. Then problem showed. when I tried to connect 4G, the status looping in "turning on...scanning(in 1,2 secs)...turning off...turning on....". I started to ask questions in here and central. Meanwhile, I downgrade to 1.34_003 since there is no solution. But, strangely, the same problem showed(i pretty sure that 4g works on the 1.34_003 before).
Tonight, I heard Fresh 3.3.0.1 out, so I flashed at the first time(wipe cache & Dalvik, no data wipe yet), also flashed flipz radio zip file to 1.77_003, problem is still on. On the other hand, someone from android central suggest to delete wimax.tree.xml, i did, still no fix.
At the last and now, I wipe everything, partition sdcard, flashed fresh 3.3.0.1, then downgrade to 1.34_003. When I tried to connect 4g, at the very first time, after half-min, the status shows "unable to start 4g", if i try to connect again, the status will be in the "turning on..." forever, i have to reboot to stop it, after reboot, the status of 4g network shows "failure". I did PRI "OTA" updates (##786# Way) to 1.40_003, same situation. Now, I m really afraid I broke something, and brick my 4g connection.
anyone can give some help here?
Updates:
I flashed WiMax again this morning, suprisingly, 4g status finally starts with "turning on... --> Scanning ---> Connecting to Sprint ---> Scanning". Unfortunately, it still cannot connect successfully. I tried to delete tree.xml, still doesn't work.

[q] lost my 3g

I can't seem to fix my signal after flashing a ROM anymore. only get 1x which is only better than no signal at all. At one time in the earlier releases of M.O.A.R I was getting LTE and 3G with no problems then later releases I've lost both. I unrooted and went back to stock and my 3G was back and rooted again, went back to MOAR and still no 3G. So now I'm on beenstalk and still cant get a signal. I love both of these ROMS hands down and would like to fix this issue without experimenting with every ROM in the forum. Has anyone else had this issue? I've resetted radios flashed different modems (except MK3) and I still end up with bad network. I need help
Open the dialpad, and then ##72786# . The Device will reboot a few times. Just let it do it's thing. It will go through the Handsfree Activation Process. This will reset your Data.

Help, lost ability to connect to T-Mobile

Hello. A couple days ago I updated stock Android and flashed the radio from xxla2 to the latest. It seemed that things were going well except that it wasn't connecting to the T-Mobile network.
I know that I messed up when I was getting ready to install, and had formatted system when I was clearing the caches.
Tried a number of things, flashing the radio back to what it was..entering the # # 36 ..etc code, whatever it is. Tried airplane mode toggles, tried available networks refresh, and on and on. Still getting a triangle saying "Selected network (T-Mobile) unavailable."
I've also contacted t-mobile to make sure that there isn't an account issue or something.
Any ideas of what I could attempt to restore service?

Worked like a charm thanks a lot!!!!!
Same issue with hotspot using super g2 rom.
I tried updating PRL but my data still goes on and OFF. Is there another hotspot mod I can use with this rom? Any help would be appreciated.
As a bump to this thread, and to keep the forums tidy, I, too, am having issues with SuperG2
I flashed it and it worked beautifully but I was unable to get any data service. I tried updating PRL/Profile but that would not work. Kept giving me a network error.
That being said, I finally got data to work (beyond me, not sure how this happened but I did NOT get PRL/Profile to update) and was using it merrily until I began to restore some files I had backed up via Titanium.
I rebooted to get the data from these files to run smoothly but after a reboot I lost all connection. It told me that my service was disabled.
I reflashed the ROM but am back to square one - unable to updated my PRL/Profile and cannot get any data, even tho the LTE logo is at the top and spinning. WiFi tethering works and I can access the internet in this way, but not in any other way.
I am being forced to go back to stock =(
Any help would be appreciated.

Connect to wifi then update the profile and prl (can be done at home if you have wifi, or mcdonalds, or starbuck, or anywhere that has open wifi)
Similar Issue
Running SuperG2, comming from Milestone1. I cannot seem to get the WiFi tether to work on SuperG2. It worked great on Milestone1. I tried the update PRL while Wifi tether is active but to no avail. I'm not sure if it's related but my signal kinda sucks too. Where I normally get 4g now I only get 3g with sparatic 4g and I also loose my signal altogether at times. I have to activate airplane mode and then deactivate it to get my signal back. I would go back to Milestone1 but SuperG2 is the frontline. Need to keep moving forward. Any help is appreciated. Thanks.
