[Q] Can't get 4G anymore :( - Verizon Samsung Galaxy S 4

I installed Cyanogenmod a while back and ever since I haven't been able to get 4G. 3G and everything else works fine. Now if I try other ROMs 4G still doesn't work. So I'm not sure what's going on.
Any help would be appreciated!
Thanks!

Have you tried going to mobile networks and make sure network mode is set to cdma +lte/evdo?

CM7/Miui 3g not working Cricket flash

I recently flashed the latest AOSP MIUI rom from Comrom 2.1. I have a flashed cricket samsung fascinate and I was wondering why my 3g flickers on and off and refuses to work. If there is a fix for this, PLEASE let me know! Thank you
I have not verizone operator and my 3g not working
I flash CM7 from evil 3.6
I dont have drivers cm7 for xp/win7 for QPST!!!!!
HelPPP!!!
evil 3.6 i have not problem with 3g and drivers
Data does not work on non verizon phones when flashed to a CM7 based rom. And I believe JT said he wasn't going to do anything about it. And since Cyanogenmod will take over the builds, I doubt it will happen.
I back to the evil 3.6 and my 3g work good
I have non verizone operator
Alright thank you that's good to know

Just for clarification, I have a Verizon phone activated on Page Plus and data worked fine right out of the box using custom TouchWiz ROMs. Based on your response quoted above it sounds like my data should still work since I am using a Verizon phone and their network even though I am not a Verizon customer? Or is it more complicated then that?
I've just started looking into CM7 and MIUI and found a couple of posts concerning data access but wasn't clear on my situation. Maybe Page Plus hasn't been mentioned directly or more likely my search skills suck. Either way, thanks for any help you (or anyone) can provide.
I'm have same problem. I have cricket also and can't get 3g to stay on. even when i wiped and flashed another rom it still flashes on and off. i have to do a complete factory restore to fix it.

Might be different for page plus go ahead and try. I know us cellular works fine on cm7 as I've seen it mentioned a few times.

WiFi totally gone from Atrix after unlock - flash

Hello,
I'm going nuts trying to figure out how to fix my Atrix 4G (AT&T).
I Rooted > Unlocked my Atrix and installed the Touch version of CWM and flashed CM9 and it all seemed perfect.
However it seems all the WiFi drivers are gone.
Trying to turn on WiFi simply makes my Atrix reboot. Trying to use some WiFi tethering tools give back a 'no Wpa supplicant' error.
The phone works perfectly except for the fact it has zero WiFi capability now.
I flashed other ROMs like MIUI, and AOKP to no avail, same issue, no wifi.
I flashed the Stock ATT ROM via a fruitcake thinking it will 'reinstall' my wifi drivers but i was mistaken.
Anyone have any ideas how to get WiFi drivers installed again? Why wouldnt the ROMs have that already?
Bit confused and would appreciate any help.

Bluetooth also doesnt work and causes a reboot too if I attempt to turn it on.
In that case, your wifi/bt chip is likely burnt. Sorry.
There's no fix, this is a hardware problem.

Radio wont turn on!?! HELPPPP!!

ok so I was running viper 4g 1.0.0.0 and everything was working fine. I then decided to flash cm10, the 8.20.2012 build, and I ran that for a few hours, everything worked great and I loved how fast the Rom was. Long story short I was browsing the web this morning and suddenly my radio shuts off, I wait a moment and then it turns back on, then shuts off and turns on intermittently. I get annoyed after 20-30mins of this so I restore my backed up viper Rom. Well now the radio on this isn't working either....someone help me please!! I also know sprint is doing work on towers and I live in the san antonio area, but I know its not them cause I'm posting this from my girlfriends EVO 3d! HELPPPPPPPPPPPPPP!!!!!!!!!!

I have been on these radios since before the roms I was using. But I reflashed them hoping it would do the trick, and it didn't. Still not working.

Could be a bad device. I would restore to stock and take it in under warranty.

Restore your phone from a backup you do have a backup.

Forgive me if I am wrong but it doesn't work that way when going to cm10 or back
I thought it was a mandatory deal to flash the cm10 boot IMG prior to flashing cm10 and flashing sense Rome boot IMG prior to going back to a sense Rom
Like I said...highly possible I am wrong but I recall reading that

My 3g has been cutting out alot too. Sometimes I have to go to settings and turn off the radio and turn it back on. I'm not on cm10. Could be network rather than phone.

WiFi Error

Can someone please help me? I've searched posts here and EVERYWHERE online to no avail and still no fix. My WiFi stopped working, won't turn on and just reads "error" My Bluetooth is the same but don't really worry about that. I have HTC Evo 4g lte S-on baseband 1.12.11.809 rooted running Viper 4g 3.0.1 ROM. Logcat states Driver failed to load etc... It hasn't been working since I was on 2.0.2 but know that ROM wasn't the issue either because it was running fine while on it, just stopped one day. Any help is appreciated.

May be the drivers. Try to find a CWM-flashable version and flash them... hope it will fix your problem.

I talked to someone at a cell phone repair store yesterday. The very knowledgeable person said to revert back to stock RUU and it almost always fixes the issue. I'm going to try it this weekend and will post results.

Nice. So download ruu then install.. Fix problem.. Hopefully... Then reinstall custom ROM? Or will the ruu make me have to root it again?
Sent from my EVO using xda app-developers app
Reverting to stock ROM + stock kernel should fix the problem (I'm not familiar with HTC, so suppose that RUU=stock ROM full flash).
This will also tell you if the HW is OK.
Then you can try to flash the custom ROM again.
Good luck.
You will have to root again after reverting to stock ruu. I didn't get a chance to go and try due to having my kiddos (single father) I'm going to try this sometime this week. I will however keep in touch and let you know bud.

LOST 4G

Flashed PA yesterday to give it a try. Had 4G for an hour or so and it went to 3G and I could never get it back. Wiped phone restored backup of Beans 19, no 4G. Put in new SIM, no 4G, reflashed newest radio, no 4G. Anyone have a suggestion?
UPDATE- Returned phone to stock and still a no go with 4G, must just be a bad radio.
UPDATE 2 - GOT IT BACK after flashing 3 different stock files. Have no clue but it worked.
Was probably an outage in your area..
