Hey
After upgrading to Paranoid Android 3.92 (or whichever was the first version based on 4.3) I've not been able to use cellular internet on my N4. I followed the procedure described, doing a factory reset, and flashing the bootloader and modem software first, before flashing the ROM. I've upgraded to the latest PA ROM (3.95 as of writing) and no joy. WiFi works fine, and I can send and receive calls and texts fine. The phone status section also says I'm connected to a HSPA network, but just doesn't seem to be able to get any data from it (no data symbol at the signal indicator at all).
Any ideas on what could be causing this, and how to fix it?
Thanks.
Edit: Issue solved, it had selected the wrong APN after resetting.

Hi.
I'm having trouble with my data connection. I was running franco r86 and flashed harsh kernels boot.img and since I've not been able to get data connected. I've tried to wipe cache/dalvik, change kernel/rom, flash the stock images (both android 4.2.1 and 4.2.2), reset APN, manually add APN, turning radio off/on in the *#*#4636#*#* menu, tried another sim card (same carrier tho). GSM works so I can make calls, but GPRS serivce says Connecting or Disconnected :/.
As I can see it, it can be software/settings or hardware fail when I plugged it into the computer to flash the boot.img (, that seems unlikely).
Any ideas? Thanks.
Edit: Got it working after selecting my APN like 15 times. Odd, but true.
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 have been running Nightlies of CM11 everyday as they are released and normally I have no problems. One of them must have tripped something. Wherever "Sprint" is supposed to be--bottom of notification panel and under the signal in the quick setting panel--it says "Roaming Indicator Off." I normally wouldn't mind but with it is the inability to send MMS or connect to LTE.
I've flashed various APN zips to try to fix it that way to no avail. I've tried manually entering the apns and still nothing. I set the phone back to stock using ODIN and LTE and data worked fine. I rooted it again and install the pre unified build of JFLTESPR and data and lte worked, then when i wiped and installed M8 again came the roaming indicator off. I'm not sure what the issue is, but I really would like to get the kinks worked out so I can have LTE again.
It a problem with the ROM that has to be fixed by the developer.
Problem is fixed, it had to do with the the rom not asking for the pin to my sim card. I flashed an older build and used it to remove the need for the sim pin and then reflashed to the most current build.
Hi guys,
I've got a Samsung Galaxy S4 with this custom rom.
Unfortunately, the wifi connection drops or doesn't even work at all. I downloaded another custom rom, Cyanogenmod 11. For me, this rom also has the same wifi issues. So I followed this tutorial here on XDA to update my modem and bootloader to XXUHOF2. (I also flashed the wifi fix for that bootloader in pda/ap).
The modem and bootloader update worked, according to these screenshots: (See attachments)
But the wifi connection still drops or doesn't even work at all.
Also, the mobile connection and wifi indicator have sometimes got an exclamation mark next to them. (See attachments)
When I go back to stock, the wifi works perfectly. (But I don't want stock because I hate touchwiz).
By the way the mobile data, texting and calling also works fine.
What do I need to do to get the wifi working?
Thanks in advance,
Twitmuck.
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.
