I just upgraded to Lollipop and lost LTE. I have EHRPD 3G only.
I am rooted and on Extreme Syndicate 5.0 Lollipop.
I have tried the usual items found in Google:
1) Removed SIM, rebooted. Put back SIM
2) Checked LTE settings under mobile networks (Global, also tried CDMA/ LTE)
3) Checked APN (vzwinternet, internet and VZWINTERNET)
4) Tried basic toggling of airplane mode, data, etc.
I am trying to avoid going back to kitkat stock and working back to lollipop.
I am hearing that a new SIM may be required but I have not gone that route yet and would like to resolve right away rather than taking a day for a SIM to ship to me.
Any help is appreciated.
Have you factory reset the phone after the update? It would be something to try.

I tried numerous things. Right now my LTE has come back however things are kind of strange when I reboot, but at least ultimately end up working. I have a new SIM to throw in there when I lose things entirely again. I'm now sort of convinced that the problem is the SIM as I have tried a few different ROM's including stock unrooted KitKat and data always acts the same. I'm now on 5.0 and it's again the same.
Hello, after upgrade to 5.0 my s5 verizon, i lost 4g, but on 4.4 it worked fine in russia

Update:
I ended up sending it to Samsung and they fixed it for free lol
Model: AT&T SGH-I337
Baseband: I3377UCUAMF3
Firmware: Stock/SHOstock
I bought a used GS4 on Swappa last week. Got it today, rooted w/ Kingo, and installed Safestrap.
I put in my old sim from my GS3 and can't get service on the stock FW or any SS-safe ROM I've flashed.
- All other radios (Bluetooth, WIFI, NFC, etc.) work with no problems.
- The SIM works on my AT&T GS3 with no problems.
Now the strange part is that the SIM is getting recognized, but is missing certain information. (See screenshot)
+ My phone # shows up and is correct
+ My IMEI is correct and matches the sticker on the back
+ Somehow, signal strength is showing up in service mode
I've attached screenshots of various service mode screens that could be of use.
Now the question is: What should I do/ how do I fix this?
Does this happen on both roms?
Honestly, I'd go get a new sim. Cheers
Yes, I've tried it on stock and 3 ROMs I've flashed.
I'll try my brothers ATT SIM when I get home today.
I'm also going to try removing Safe strap and root, then factory resetting.
Sent from my SGH-I747 using xda app-developers app
- UPDATE -
So I successfully removed Safestrap via ADB, removed root, and factory reset from stock recovery.
The no service problem still persists. I guess the only things it could be now are:
+ My SIM is somehow messed up, as xBeerdroiDx suggested.
or
+ The SIM tray needs to be replaced.
The original owner called me today and affirms that the phone completely worked before.
Does anyone know what else internally could be causing this?
- UPDATE 2 -
OK now I'm at a complete loss. I tried other working AT&T SIMs. Nothing.
Tried replacing the SIM/SD card tray. Also nothing.
I've flashed all stock MF3 and reset EVERYTHING.
I've even gone as far as enabling the service menu and doing a NV_REBUILD multiple times.
Only thing I haven't flashed is a new .PIT because of the signature checking issues with MF3.
It's weird, because I can get a signal if there is no SIM inserted. And I was able to enable data and LTE functionality at one point by messing with the service mode settings. But that was it. No calling or cellular functions.
Could it be that my /EFS partition is somehow corrupt?
I'm getting close to giving up and seeing if Geek Squad can send it in with no warranty/coverage. I don't enjoy having a $400 wifi browser.
Hello, ive acquired a Rogers s4 i337m that has been sim unlocked and rooted, and possibly aws enabled. It has worked for about two months on Wind with no issues and all of a sudden it started dropping signal and lock into roaming mode.
I've done many firmware upgrade and downgrades, flashed custom ROMs and different modems. Formatted the /system, data, cache, dalvik.
On a fresh install it looks like it works. Until I put the phone away. After about 30min to an hr the phone automatically switches to Roaming and I don't even have an option to select Wind as a network provider.
Anyone with similar issues could please xhime in?
Just switched to 4.4.2 bootloader and modem (NC1), with Kangapop Rom
Anyone?
Keep switching firmwares and different modems, as well as playingwith Debug Menu. It will stick to Wind for 5-10min with choppy signal, then switch to roaming and never give me Wind option again

back up your phone in kies first.... incase....take sim out... upgrade to new software... go in recovery and enable cp logging. and clear cache... dont have to do factory reset but if you want to have a clear head go for it... then push the aws via qpst... once restart push the phoneutil.apk via sd card... restart with phone. and that should fix the prob
:good:
First off I'm using an unlocked S5 on straight talk's LTE network, have been for about 9 months with no problems. I've talked to support twice and they reactivated networks and all that good stuff, and when none of that worked sent me a new sim, which I have just activated and it still didn't fix my problem - so I'm finally bringing my issue here.
Last week I decided to update from phoenix rom oc4 (I think it was oc4) to optimal rom og5 (15-5). Anyway I was hasty in flashing and messed up, so just went back to stock ncg > root > full wipe > flash firmware, rom, kernel, firmware again just to be safe. The rom works fine except I seem to have lost my data connection. The 4G icon still shows, but it's not filled in - as you can see in the screenshots. To make it even more strange, when I check the network and sim card in apps like Advance Signal Status and Sim Manager, I still seem to be getting a connection to 4G but there is just no data flowing. The only error I can see is in phone info, when I run a ping test, I get PingIpAddr: Fail: IP addr not reachable which you can also see in the screenshots. It would appear this is my problem but I don't know where to go from here. I'm going to start flashing different versions of modems, starting with oc4 to see if that helps. Then I'll probably try different roms, but I've flashed other roms trying to fix this and even restored the backup to when it worked and it still didn't fix my problem. Did I wipe my IP address or something maybe? I am in CDMA/LTE mode, and the vzwinternet apn is selected.
For starters try to put the apn settings for your carrier and if not sure call them and ask them to email you the setting
I fixed it, went back to stock ncg instead of ni2 and that worked. Weird.

Hello folks,
Galaxy S4, Play Edition, currently rooted and AOSP 7.1.2 installed.
I rarely used data on this phone and never since I installed the ROM. Lately, I needed the data often and I noticed that I do not get the data on this ROM. I confirmed with the carrier about the APN settings (Airvoice Wireless, att MVNO). The carrier reset data from their end. I tried manual APN entry but none worked.
Searching on the web led to various ideas, like reset network settings, airplane mode on/off etc etc. Tried everything, no change in the status quo. I am at loss on what is the problem. I tried the SIM in my wife's phone (HTC One X, Kitkat) and it worked without any issue.
I could not figure out PDA, CSS but the baseband version is I9505GUEUDNL3, in case if it needs an update.
I checked the thread (https://forum.xda-developers.com/galaxy-s4/general/ref-galaxy-s4-i9505-modems-bootloaders-t3315987) over and over but didn't understand what/how this stuff is worked out.
I am really going nuts and I do not want to pony up for a new phone at this moment.
Any help is appreciated.
Flash back to a stock ROM and check for data connectivity. If everything works, it's a ROM issue rather than being a hardware issue.
The issue seems to be related to the ROM.
I restored to 5.0 (LRX21P.S012.141205) and the data works flawlessly.
