So here I am...that guy. I bought a Sph-L720 and I didnt check until It was too late. I think the previous owner downgraded the modem. It was running a stock rooted rom when I bought it Mk2 I believe but am not sure. I have since installed a complete mk2 stock firmware, modem, rom all inclusive which was downloaded from this forum. Anyhow any help would be appreciated in getting this thing up and running. Shows 3 bars of service.... just no data. Has a sprint sim card installed. Thanks ... - Dave(that guy)

Hey guys...
I just rooted my phone, installed TWRP and flashed my first rom. It installed no problem, but I didn't have any network access so no phone.. kinda pointles.. Guessed it coulda been a bad rom so flashed a different rom and had the same problem. How do I get my network access back...
1st rom was MIUI and second was The Blu Kuban.
Use to flash my OG Evo all the time and never had this happen...
Update the prl and profile

Its all there, has my number as well.
Only other things I can thing of is modem or APN but with apns you should still have signal, and with modem it won't flash through recovery so idk man I'm sorry.

I am having the same issue. I have also updated PRL and Profile. Device information shows as normal. I've gone to complete unrooted stock and still occurring.
Hello ever since i flashed the crawjs MF9 tar my lte speed is terrible and my friend same phone stock gets 20mbps where i get 1mbps if that ive flashed different roms hoping to fix it i updated profile and prl still no luck someone help me thanks in advance
Go back to stock unrooted and perform a factory wipe.
Or also on a touchwiz ROM do a ##72786# in the dialer. It reactivates your phone.

First confirm that your baseband and software version say mf9 in about device. If not you need to install the modem again. I have experienced, on occasion, where installing the stock tar from Odin doesn't always update everything on the first or sometimes even the second try. Also what Rom version is your friend using? If your modem is mf9 and his is something else maybe the modem is a problem in your area. I am using it with no speed issues.

I know this will sound odd but Odin the tar a couple of times back to back or until about device shows mf9 for everything.

Yeah or completely stock mf9. Either one will work. It happens to me also. Not sure why it doesn't always take on the first try.

No I haven't had that problem. But I also just got 4G in my area about a month ago so I don't have very much time on it.

I have no idea what that is lol. when i mean noob im mean like only ever flashed once. where can i get mk6 radio?
Modems/baseband/radio is all the same.
Could also be simply APN settings.

SO i did a bit of research and understand that if this is the problem i need to flash MK6 onto the phone? and i need to use odin if im correct?
becuase reception and data wasnt working ive returned back to using the Darthstalker version 4 rom.
version 4.2.2
baseband i337mvluamdj
im assuming that i do indeed ned MK6 to run Dartstalker version 10 rom on andorid 4.3?
I'm running sacs rom. And last night sometime I lost my mobile signal. I'm unable to make any calls and have no Internet. And yes I paid my bill. If someone could point me in the right direction it would be greatly appreciated
Sent from my SPH-L720 using xda app-developers app
Does it show no signal bars and has a red X in it?
I had this on stockish v4 two days ago while I was messing around with random files. I was able to solve it by dirty flashing the ROM again. Then connecting to WiFi and updating profile.

No. I don't have anything. I even did a clean install of newest rom. I connect via wifi and I get a preparing network and searching for service.

Okay so I figured out that my radios suddenly disappeared. I tried flashing the latest radios through Oden with a pass. But they are not sticking. Any ideas?

You'd need to flash the exact same modem as you had before, however it makes no sense that the modem would just disappear.... Are you sure nothing happened?

You can try calling Sprint have them reset service or if you have insurance on it take to sprint store, you may have to take it in as stock unrooted. My S4 was doing same thing, but I didn't have insurance on it, so had to send (unrooted) in for warranty service through Samsung to have it fixed.
