So I wanted to some porting but I fudged up my phone by flashing to the modified nexus ROM and now whenever I want to activate my phone I have to go on WiFi. I already set it to ting and MMS/SMS/calls are working fine. I get data but only 4g. When I set my PPP carrier settings to sprint, I get data both 4g and 3g but ionlyget 1rxtt. Can anyone please help?
I tried returning to stock but nothing. I'm on stock. Right now.

(TL;DR at the bottom)
This morning, I swapped to my old Evo 4g (rooted as well) because I was going to be doing community service all day and didn't want anything to happen to my Epic 4g.
First thing I noticed was that there was no 3g on my Evo. I shrugged this off because 4g was working, and I only needed data for a short period of time.
After switching back to my rooted Epic, I followed the instructions, and it reset after putting in a stream of numbers and symbols.
When booting, I saw a custom boot animation, but everything else looked pretty stock. None of my apps, stock TW launcher, etc.
I shut off the phone, booted into recovery, wiped, and did a nandroid restore from yesterday's backup. Then I updated profile and PRL. I was able to make calls and send text messages, but no 3g (symbol said 3g with grey arrows though).
I also tried flashing a new ROM, but that didn't give me back 3g (symbol was still there).
I haven't been able to try 4g on the Epic yet because I haven't been able to get back to the side of town where the 4g towers reach.
Finally, I called Sprint to see if they could help me out.
They ran me through updating my Profile and PRL, turning WiFi on/off, turning 3g on/off, and even manually setting some of the network configurations (using MSL's, changing MSID, etc.)
After a good hour on the phone, I still have no 3g. D:
They told me that they put in a "Network Support Ticket" and some technicians will work on this for the next 36 hours.
TL;DR: Swapped from Epic --> Evo --> Epic in a 24 hour period, and there is no 3g. Tried updating Profile/PRL, flashing a new ROM, a nandroid restore, and calling Sprint, but still no 3g (even though the symbol is still showing)
Can you guys please help me shed some light on this?
Thanks!
(In case it matters, I'm running the Stock+ ROM from the Mortify Thread)
I really am not sure but you should try calling Sprint, pulling out the battery and ask for an RTN reset. I used this off an Evo thread when I had connection issues with my Epic after going full retard and doing an EFS clear with Odin. The RTN reset on the phone didn't work for me so I think it is different and the tech told me they have resets for voice, SMS, and data but I forget which this is for. If nothing else ask them to do a voice, SMS, and data reset on your line.
Sent from My Phone with An App.
I was just about to call them, but had an idea.
I unrooted and 3g came back!
Shortly after, I re-rooted, and am happily using 3g
Thank you!
If anyone else has this problem, I used this to unroot, and this to re-root.
XDA community, you're the greatest
Glad to hear you got it working. Odin works wonders!
I have my Galaxy Nexus running CM10 (don't think that would make a difference, but who knows?). I was able to connect to 4g a few weeks ago, but recently I have found that I am unable to connect to 4g. I live Manhattan, KS and Overland Park, KS which are both Sprint 4g markets. I turn mobile data on and select LTE/CDMA and the phone just sits there without any data connection. Sometimes 3g will pop up, but that doesn't happen often. I have updated both my PRL and Profile from Sprint, but that didn't do anything. Any suggestions?
More on this. I re-installed CM10 and 4g was working fine until I connected to the Wifi network I usually use. Once I disconnected from that, I can't get 4g again. Can anybody help?
Probably an issue with the nightlies.. Make a backup, wipe, and flash back to stock?
Rooted and tether enabled stock JB is actually quite nice, FWIW.
I have and love my old GNex. I have had it rooted for a while and have been using CM10 and CM11. 4G has been added all over my area and the coverage is rather good. I am having some problems with the CM roms. CM11 I get no 4G and the 3G go in and out so much the phone is not useable. I went back to CM10.2 and I can get 4G again but the hand off to 3G just leaves me with signal bars and no data.
I have not tried going back to stock rooted but I will do that today if I can find the rom (link is dead here).
I have read and googled a bunch of different things and settings but which is correct?
When I enter *#*#4636#*#* What do I use as the preferred network type for Sprint??
What do I choose as the Network Mode in CM10.2?
I will start with this and if it still refuses to work properly I am just going to go back to stock. I need a usable phone more than I need a rom.
Thanks
Hi, it's been a while since I posted on the forums. I've had a problem with this for a while now, but never bothered to ask you all. i don't get certain types of signal with the stock rom and aosp roms. For stock, I get 4g data, and I am able to make calls while roaming but not while I am on regular 1x (connects but I can't use it). Also, signal is iffy, sometimes it connects/randomly disconnects. For aosp, I get almost no signal, only roaming. I think that I didn't mess up my efs folder, my imei is still the same as the DEX on the back of my phone. Do you guys know what is wrong or how to fix this? I want to be able to use my phone again...
What modem are you on? Firmware or ROM? I'm using NE2 with rwilco's stock ROM and a GSM sph-l900 with t-mobile... I get 3G and 4G (hsdpa+)... before I use to get lte/3g/1x and I use roam control when I'm in an area where I know I don't have a good signal...
I flashed the Lollipop version of Liquid Smooth on my AT&T G3 and at first everything was working fine, 4G included. After a couple of days 4G disappeared. When this happened it didn't just go to 3G, it lost all data service completely. I originally figured it was the ROM and flashed back to the previous ROM I had using the TWRP backup I made beforehand. Same story, no data service. Figured maybe it was the modem so I flashed a working G3 modem on here, same story. I flashed to a different Lollipop ROM, Resurrection, to see if that fixed anything, nope. This is the ROM I currently have installed. At this point I went and look at the mobile network options and immediately noticed 1 issue, the preferred service was 3G and not LTE. I had an option to change it to LTE but when I actually select LTE it doesn't actually switch, it just stays on 3G.
The one good thing I managed to do was switch the APN to one that worked with 3G. The APN that was originally set was "pta", I can provide the actual APN information if that'll be useful but I figure most ROMs are going to have similarly named APNs. 3G works on at least 2 of the APNs listed for this ROM, "broadband" and "wap.cingular".
I called AT&T and determined that I my 4G service wasn't cut off; not that I really thought it was anyway as that wouldn't explain why I can't even select 4G as a network type. I'm kind of at a loss as to how I just randomly lost 4G access without actually making any changes to the firmware or OS of the phone. I'm also at a loss of how I can get it back.
And I am just sitting here with 3G with speed of 2 Mbps...
No one has any ideas or advice?
