[Q] GS4 No Network after Flash - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

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

I have updated PRL and PRofile and still no network. It's not just data, it is all network connectivity period. Can't make calls or anything.

Go to your settings>about device and see if your imei and everything is still there

Get back 4G/Lte icon in status bar?

I am on Omega rom and after flashing the me2 stock and then Omega I have noticed my 4g icon has gone and it has been replaced with 3g. I know I have 4g because have done a speed test and it is around 3.5mb to 5mb per second compared to 1.2mb or so on 3g. So is there a way to get my 4g icon back? Thanks in advance.

Go to About Device -> Status and see which Data Type is displayed. 4G is displayed as LTE:14. 3G+ is displayed as HSPA:11.
3~5mbps is normal for 3G and not 4G. You are probably not getting 4G connection.

I checked my status and it is UMTS:3 on 3g and HSPAP:15 on H+ and I am with Telstra in Australia in a 4g area. It would display 4g when I was on stock.

LTE is probably disabled on settings then. My phone came disabled by default for some reason. To activate it go to Settings -> More Networks-> Mobile Network and check if LTE/GSM/WCDMA is enabled. That's probably the problem you are having.

Oh. I heard people having the same issue after flashing some firmwares. The one used on Omega is probably bugged for you. It doesn't happen for everybody. Try going back to stock or flashing a version of Omega that is built on top of another firmware version. I can't help you anymore. Good luck

Is there a way to extract my Baseband version (radio) from my stock TWRP backup. When I flash stock Telstra back my baseband stays as Me2 could this be the 4g issue, wrong baseband for carrier?

That's probably the issue. That's why it works for some people and not for others like you. I don't know how to extract it. I'll let other people answer this.

I have sorted it out all good got my LTE back.
1. Flashed stock Telstra backup with TWRP
2.Flashed Stock rooted ME2 with Odin 3.04. (3.07 doesn't contain the pit file and seemed to remove my LTE)
3.Flashed TWRP with Odin 3.04
4.Flashed Omega 3.0 with TWRP
All good with LTE and WiFi nice:laugh:
PS. When I did a factory reset in settings I lost my LTE when phone rebooted( wont do that again). It seemed to format the 2Gb partion for LTE settings dont know if it has something to do with TWRP just a guess?

I did that. They said go back to stock rom and then flash again. I'm do nandroid back to stock then see if comes back.
Okay nandroided back to stock and still no network mode option. Honestly i don't remember seeing that before I even rooted. So maybe an Odin flash to stock could help other then that I'm not sure but according to status bar it's says 4g lte good enough for me
I also noticed my phone doesn't say galaxy s 4 when I power it on anymore just says Samsung with the custom lock
That's because your bootloader is unlocked and/or system and firmware status is custom.

Terrible after flashing Tar

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.

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.

Updated to 4.2.2, get no signal now

I restarted my phone, reinserted the Sim tried everything I'm still not getting signal, anyone have this problem?
Sent from my Nexus 4 using xda app-developers app
How did you update? OTA, flash ROM, etc...Have you tried SIM in a different phone? Could be a bad radio? What does your baseband say in System> About phone?
It was the official OTA
I never updated because 4.2.2 killed LTE but then I did anyways
My baseband says unknown
Edit: the 4.3 update came, I tried updating but it said error half way through wtf!!!
Sent from my Nexus 4 using xda app-developers app
See this a lot, updating killed the radio. You probably don't have an imei number either.
Try flashing an official factory image.

Don't waste time with doing anything else. Flashing the factory image will not get your imei number back and without it, you will never get a signal. When you call to RMA it, be sure to tell them you lost the imei number during the upgrade process. They should have plenty of lost imei cases in the system already.

Regardless it's safe to just flash the factory update, then see where you can go from there if all fails use that as your last resort

Lost mobile signal!

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.

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.
