Hello,
I seem to have messed up a setting somewhere in the *#0011# service menu and my S4 will NOT connect to EVDO. It will, however, connect to LTE and CDMA1x for voice.
I've tried NV restore and even ODIN flashing back to stock MDC to no avail.
I've run out of ideas!
Thanks!
Well I stumbled across this post: http://forum.xda-developers.com/showpost.php?p=42482339&postcount=10
Running the ##72786# re-activation code seems to have resolved the issue.

After factory data reset phone can't see GSM network and can't register. It says NO SERVICE. SIM card ok. check at another phone. What can be a problem and how to fix it?
Some info below:
fw: 2.1update1
baseband i9000xxjf5
kernel 2.6.29
build ECLAIR.XWJF7
csc i9000serjf2
p code: gt-i9000hkxbri
Have you checked your APN settings?
I can't make even phone call. APN...What to check in particular? wifi and gps are working fine. tried service mode... it says signal strength 0db.
My wifes is the same way it cant lock on a service provider after factory restore only way it works is with a custom rom cant figure it out
Contact your network and enter mobile network settings manually .
jje
flash to custom rom maybe?
it's your APN settings
just google your APN settings... i.e. i'm with Bell mobility... if I google Bell APN I will find the info I need... that data goes into settings>wireless>mobile networks>access point names
hit the menu button and add apn.... bell's examples are here http://androidforums.com/samsung-i7500/87145-bell-mobility-apn.html
they are carrier specific obviously
Hi All,
This happened to me before and I was as frustrated as you and when I was about to give up, I tried one last restoration, but only this time I did it correctly. After that, I restored 5 different versions of Samsung Galaxy S stock ROM back to my Samsung Galaxy S. One of these versions were Chinese, and everything was in Chinese.
Samsung Galaxy S had no signal was because the modem file was missing while you were performing the restoration.
Now, all you have to do is go to this page and follow the instructions to restore the Stock ROM back to your Samsung Galaxy S.
You can try to install a different rom just in case. I had the same problem and i tried to fix it applying different modems but that wouldnt work so i ended flashing cyanogenmod and back to another custom rom and that did the trick.
Even flashing back to the latest official rom for my country and operator.

Background:
- Sprint L720
- International unlocked with GSM SIM
After updating to a new 4.4 ROM (Slimkat) and NAE (modem only from the modem thread), connecting to anything other than EDGE causes, what seems to be, a modem crash. If I force "GSM only"/2G connection, it's stable with EDGE. If I try to connect to 3G, I see "3G" quickly flash on the status bar next to the signal indicator (I have full service), and then the whole mobile connecting drops and resets... then it goes back to having full service, but no data connection at all - until I got to mobile settings and set it back to "2G" and it goes back to stable EDGE.
I am overseas with the phone (it's fully unlocked and I got a strong H+ connection with the old CM ROMs at the same location), so I am wondering if it's an issue with the new 4.4 ROMs not supporting GSM? Perhaps some sort of baseband/modem mismatch? I also flashed NAE (modem only) as well when I did the ROM - I have since downgraded, but perhaps it isn't fully downgrading?
I applied the MF9 full one-click, no joy ... I did a factory wipe and applied the 4.2 factory image from SamMobile, no joy...
Looking at the logcat, I see something along the lines of an error for 'Mobile network type unknown: 0'...
Any help would be greatly appreciated - only having EDGE is driving me nuts, especially when my actual mobile network here is very fast..
Let me know of any information I need to provide - Thanks
Ok, update - I applied the MK2 modem and then NAE, as I saw someone else do because they said that the NAE file is missing some things... no joy
This all seems to have happened after applying the NAE modem-only file - Does SlimKat not support GSM? I don't think it's SlimKat, because, even going back to the fresh "Factory default" flash that I got some SamMobile, I still had the same issue..
Which leads me to what I think the problem is - the Qualcomm settings. Those seem to be persistent across all ROM restores, so how do I go about resetting the QUALCOMM settings to default? Is there something I can do with EFS Professional/CDMA Toolbox or something?
I seem to have no data when I flash back to Touchwiz. I need to do this in order to fix GPS since apparently it broke again in CM11. I was told the fix was to get a lock in TW and then restore my backup of CM11.
When I flash: StockRootedNAE.zip, I have no wifi/mobile data/cellular connection. I have the NAE firmware on my phone.
So how do I get mobile data on TW?
Any input?
No input at all...?

I have experienced several no data sessions on cm11 nightlies over the past month or so. I thought it was maybe the ng2 modem so I odin back to nae and had the same thing. wifi seems to always work but mobile data appears connected but wont actually send/receive any data. I have no idea what caused this however if I go settings>mobile network settings>prefferred network type and change it from LTE to 1x and airplane mode on then off then let it connect to 1x for a few minutes then change back to LTE then airplane mode on/off then it connects back to LTE for data successfully. Hope this helps!

My CM11 issue is GPS like I said, not data/wifi/cellular. The latter problem is on TW when I flash the zip I mentioned, even with NAE firmware...
Hoping for some knowledgeable assistance here because FreedomPop has been no help. Two issues, probably related:
I have the SPH-720T 0A3 activated with FreedomPop but it only works over WiFi. I can't connect over 3G/LTE.
I get the Sprint Hands Free Activation on bootup and whenever I try to update Profile and PRL.
I'm rooted and have TWRP. I've tried a couple of ROMs, but they had the same behavior, so I reverted back to stock. I tried changing to CDMA mode and that brings up the 3G icon, but still no data access. It boots up with no APN checked and without the FreedomPop APN; I added the FP APN, but it doesn't help and disappears on reboot. I tried changing MDN and MSID to my FP phone number, but that also hasn't helped and they revert back on reboot. Mobile data is on.
I would appreciate any help on figuring out what exactly the problem is and whether I can fix it or if there is something I can go to FreedomPop or Sprint with and tell them what needs to be done. I'm new to all this but don't mind learning or following directions.
Many thanks.
Hi,
I recieved replacement board for my H910PR, ordered an ATT H910 board and it came with H910 10l firmware.
I made a full dump before flashing H915 10e kdz and yet I don't have signal. Only the sim is recognized. If I go into Hidden menu and try to select LTE bands it says FAIL, if I select network mode as GSM/WCDMA/LTE, it pops SUCCESS but doesn't lock on the signal. Only the simtoolkit works and Service Disabled appears.
How can I restore my H910 10l full dump via patched LGUP ? (eventhough I cant verify if radio works)
I even rooted with dirtysanta, yet its the same story after applying the signal fix. Even when I flashed H910_10r firmware with TWRP, there is no signal at all. Is there anyway I can reset the modem setting? I even written a generic IMEI via MID settings but to no avail.
Please advice Looks like I wasted another 100$ on replacement mainboard
Edit: Forgot to add that Baseband, IMEI everything appears as normal. my IMEI appears as clear in AT&T database as well.
I'm making a second guess that modem is not functioning on this device despite everything appearing as normal.
Update # 2:
It's not the IMEI that's the culprit but the nonfunctional modem. It simply doesn't work with LTE/GSM/3G. IT doesn't catch a single signal bar. I get Service Disabled while sim toolkit correctly shows my sim card options. In the hidden menu, RAT selection gives me error when I try to switch network mode or select an LTE Band. Everything there fails. I even tried Factory Reset R&D and it doesn't work. Radio is permanently gone.
