Hi,
I flashed now 2 different roms from this forum, going to stock before with LGMLauncher and it's always the same:
After a couple of days I lose my IMEI and no signal from network.
Also, when I try to flash modem/baseband i receive the error "Failed to mmap aboot. Error loki-fying the boot image"
When I reflash the rom everything works fine until I reboot, that's where it stops working.
I use CWM for recovery.
Thanks.

I've gotten my phone into a state where I see signal bars, I can make calls and send texts, but no LTE or H+ is displayed and if I try do anything involving the internet it says there's no network connection. Wifi works just fine.
Here's how I got into the predicament. I should have learned my lesson from last time I flashed a Verizon ROM, but I didn't, and I flashed SkyNote RC9Z-3.9.1. Data works just fine in THAT ROM, but any subsequent ROM flashed after that... the network data is completely HOSED. I've tried enabling and disabling network data in settings. I've tried flashing the Devil kernel. I've tried restoring several different ROMS from nandroid backups. All restore fine and all have completely non-working network data. Last time I ran into this I had to flash the stock image in Odin to fiz the issue. This time however, that didn't work. The images flashed successfully, but upon reboot all I got was a a welcome screen bootloop of the samsung swirly logo and the T-Mobile logo.
I'm guessing this has something to do with the 4.3 bootloader? I'm downloading T889UVUCMK7_T889TMBCMK7_TMB.zip from SamMobile site and boy is it taking FOREVER! 7 hours left on the download. My thinking thoug is that If I unzip this new 4.3 firmware and flash it with Odin (or Kies if I absolutle have to) my device will start behaving again, and Network data will work, and I can go about ROM flashing and hopping again (though I'm gonna stay away from those Verizon ROMs let met tell you!).
Does anyone else have any other suggestions on what I can do to get my data back or to patch my bootloader to the 4.3 version? I was looking at this thread and wondering if it's safe to follow this procedure for patching once I have installed the 4.3 stock image:

I have a samsung galaxy nexus by sprint. I was recently using CyanogenMOD 11. I put it into airplane mode and when i tried to turn if off, the radio would not come back... so I decided to go back to stock rom and flashed it back to Android 4.2.1 (GA02) via wugfresh toolkit. After flashing I noticed the phone was not picking up any bars to the cell tower so I first performed factory reset. After that was done I still was not able to connect to the cell network, so I let it upgrade to 4.3 via Wifi (works btw). Stll not connecting to tower.
At that point I remembered I may need to perform a carrier wipe and on my phone I entered *#*#72786#*#*, then it asked for the MLS number which I entered (double checked it with my carrier so I know I'm using the correct MLS ID) and after entering it, the phone returns the following error:
Modem Error
Modem Exception Occurs
And there is an option to push "yes" nothing else. If I press yes, it goes back to the dialer and nothing happens.
If I attempt a PRL or Profile update, I get the following message
Error
The PRL update could not be completed. Please try again later
If the problem persists, you may need to contact customer service.
Error: (Code: 8)Unknown Error
Also there is a line showing up during.
sprintaccount username(Device ID) is null...
Is there anything I can do to get the phone to connect to the network again?
Thanks,
As an update, it appears the radio is just not being recognized at all. Settings>about phone>Baseband Version = Uknown
I have attempted to flash different radios (GA02 and FH05) which says it was successful (TRWP) but still no radio. No idea what to do from this point.
While traveling away from home, I noticed a large area with no coverage, so I tried to update my roaming capabilities through *228.
The phone rebooted and has been showing "no Signal" since. I could be standing right below a tower and still get the no signal message.
I'm not trying to reflash it, but always get the same problem. I reflashed various versions of boot.img, recovery.img and of the ROM, but always with no luck, the phone is always stuck in No SIgnal mode. Wifi runs fine, so I assume it's not an antenna problem. I'm running the TWRP tools 4.2.3.1 and the x3reme Sense ROM. I can connect it to my computer, and send adb or fastboot commands, not problem.
One problem may be that when I try to wipe the phone clean, I get an error message "can't mount /sd-ext" and the script aborts. So I never fully wipe the phone.
How can I fully wipe the phone? is this what I should be doing? Do I need to go back to CDMA tools to reconfigure?
Thanks in advance!

Interesting things can happen when trying this function:

I don't say you have damaged your sim card already but it's might be worth testing with different one rather than changing kernels and roms.

Interesting point. Thanks.
I should add that I have a CDMA phone (Verizon/VM/PP...) flashed for Page Plus.
Still, I suspect something was written over and this is why I may have to use CDMA workshop to look into this.
Or wipe it and start over.
Does anyone know?
As an update, turned out the problem was in the PRL file.
Using CDMA tools, I reloaded the pageplus.prl file and the system came back alive!
I hope this helps someone else.
I just recently flashed HispAsian_BlackOut_v0.2 and also odin NH7 modem. Now when I try to make phone calls, nothing happens. As in, I try to dial a number and it just stays on the dialer and it says "Process com.android.phone isn't responding"(I can still send/recieve text and use data). I tried reflashing the rom, the modem, updating the NH7 Firmware and I still have the same problem (I always do a full wipe). Any ideas how to fix this?
Even though i updated the firmware, it didnt work the first time.
Hello everyone. Looking for some help. I suddenly lost the ability to use WiFi. I have 4g and cell service. When I try to turn on WiFi my phone reboots. After the reboot I get a message that the phone is in factory mode. I opened my EFS folder to make edits but it is empty. Can anybody help?
EDIT: I'm currently on 4.4.4 NH7 rooted.
Try flashing stock firmware, ShinySide has a link in general to download samsung stock firmware.

I flashed the stock firmware. Wifi is somewhat working without rebooting. After a reboot i still get a message that factory mode is on and the phone turns off wifi. I also have to re-enter my wifi password to reconnect. Any ideas on how to turn off factory mode?
EDIT: Also when I trying flash anything in recovery I get a message in red saying unable to mount efs.
Try this Samsung Galaxy S4 : How to Get out of Factory Mode: http://youtu.be/d8dbrerUacw

I already tried that. But for some reason my efs folder is empty. I'm guessing I need those files.
EDIT: Anyway someone can share their EFS folder?
Even after flashing stock NH7?
Try reflashing again, maybe open nh7 rom on pc with adb and copy content to your folder and reboot.

I've flashed Shiny Sides modem through Odin. Then I followed it up by flashing his NH7 Stock ROM. No luck. The positive is that I have WiFi working again. The Bad side is that I get the "Factory Mode On" message on reboots and I have to re-enter my WiFi password.
What roms where you running before ShinySide's rom?
Where you on CM11?
Check your bootloader.

I was on Phoenix Rom 4.4.2. Then I flashed Eudemony 4.4.4. It had some bugs so I restored back to Phoenix Rom. This is when my wifi and factory mode on issues began.
Try flashing Phoenix again, see if that fixes it.
Pp.
Panch, thank you for sticking around and trying to help me find a solution to my problem. I'll give re flashing Phoenix a shot later today and report back.
