Since I flashed my phone with the new version of Lightning which is a modified version of the stock ROM XXKH3, it came with the matching new Baseband version I9100XXKH3.
Since I installed the new version, my packet switching mode on the phone (ie internet only, phone function works) keeps dropping on me at random and only a full restart of the phone fixes it.
A friend suggested that my phone may not like the new Baseband version and I should flash it to a older version.
Might this resolve the issue? and if so, where can I get just baseband files to flash instead of full stock roms?
My original stock firmware was MUGKG2
Please advise, thanks in advance.

Thanks for the info
From that post I also found http://forum.xda-developers.com/showthread.php?t=1193695&highlight=modem which is the exact modem my phone originally came with.
Seems the key is knowing the right terminology for some things. I was searching for baseband and radio when I should have searched for 'modem'.
I'll try flashing the old modem back and see if it fixes my issues.
Okay so I unlocked my galaxy note just by using a non accepted sim. And I figured it was good since it said unlock was successful. However I didnt test it. I then flashed ICS clc5 leak and a tmobile baseband. No Go... baseband unknown. So I wiped and reinstalled ICS. I ended up with a baseband but also an evil little circle at the top with a line through it. I though well hmmm... I gave up and odined pure stock with a baseband but still no signal. The signal came in and dropped after seconds when I turned it on. I added a new APN still nothing.
I just want to get this working with att or not and I am beat.
I have no signal here is my system complete stock.
ANDROID 2.3.6
base band 1717UCLA1
kernel 2.6.35.11
build number GINGERBREAD.UCLA1
Edit: So much for questions and answers....
Hi all,
the new build for G925W8 is out MM. G925W8VLU5CPI4 and it messed up the bootloader and modem/radio. its working fine but i want to downgrade back to MM. G925W8VLU4CPG5 which the new build replaced. but now when i odin the old build baesband goes missing and no network signal. then i flashed the modem from new build and baseband and network came back........my question is why modem/radio from pg5 build is not working anymore? how can I make it work? i flashed it and also other older modems many times with clean installs and none is working no baseband. your help would be greatly appreciated. thanks

Because once you upgrade your firmware you can no longer downgrade. So when you flashed 5CPI4 you can only flash firmware that is 5xxxx. You can not downgrade to 4xxxx firmware. They have different modems and bootloaders.
I have a Moto E 2015 XT1521 (4g/LTE India, Dual SIM). Yesterday My phone rebooted when I was trying to force data connectivity on 3G by switching to airplane mode and back, and the phone lost its baseband (No SIM cards detected, Baseband unknown displayed, no wifi either). Was running 5.1.1 LP Tesla OS. Reflashed with stock XT1521_SURNIA_RETASIA_DS_5.1.1_LPI23.72-65_cid7_subsidy-DEFAULT_CFC.xml (was on this ROM b4 changing to Tesla last year). Still baseband unknown, Flashed the two NON-HLOS.bin and fsg.mbn from the same 5.1.1 ROM. Still no baseband. Can I flash the two files from the 5.0 initial release / 6.0 MM final release Stock ROMs (RETASIA Indian ROMs)? How can I get my radio baseband back?

Can't say what happened, but you can try flashing latest 6.0 MM but won't guarantee it will work or not,
Never heard of this problem before

Just a bit wary / reluctant to upgrade. Bootloader version changes and cannot be downgraded, more chances of a brick if trying to downgrade.
Personally i have liked LP and user opinion says that MM upgrade makes the phone lag, stutter and possibly phone lacks appropriately boosted ROM/hardware. Should I take the plunge?

But not sure it will work or not

OK, so i took the plunge and flashed the MM stock ROM as advised by @Sher1234 in the fond hope that IMEI and Baseband will be restored, but at the end of it i have been awarded with a MotoE that works like a tablet sans WiFi and SIM cards (No radio baseband, NO IMEIs)!
Terminal commands for flashing were all OK, see attached txt file for ref (flashed from a Linux 32 bit machine)
Spoke to the repair guy, who advises a motherboard change (which will cost Rs 2500-3500). I am wondering if it's worth it or not.
I own and use XT-1521 here in the U.S. - are you using the latest squid TWRP specific to the Moto E ? Did you do a factory reset, wipe clean and then a fresh/new install, etc. Did you verify your micro-sim cards are valid & working on another smartphone. Checked your APN settings for the network being used ?
If they all checked out, try switching in/out of Airplane Mode - so everything works in WiFi mode, including WiFi (VoIP) calling mode ?
I have been running Remix rom for a while, using the latest - might want to give it a try. https://forum.xda-developers.com/moto-e-2015/orig-development/rom-resurrection-remix5-5-1-t3160059
@Letitride, the SIMs work on other phones. Yes, using Squid's TWRP recovery. System does not see any SIMs on the phone and WiFi fails to initialize, and the same happens with the FM radio too. Cannot disengage/engage airplane mode, as that tile is greyed out.

The reason it says your on the latest firmware is because you are rooted. At&t firmware is hard to come by as they lock the bootloader and device down. If you are not bothered about root flash stock firmware and you can uodate OTA.
I have the same problem except that my phone is not rooted, im on stock AT&T Android 5, but it still says i have the latest firmware.
Someone told me that it has to be connected to AT&T cell towers to find the update but even that didn't work for me.

I will give it a shot but first i need to find the stock firmware because its hard to find for my device specifications, and i will let you know if it worked for me
Edit: flashing the stock firmware locks phone to only at&t network since i use different network i will not try to update it
