A few months back I went back to stock, and then flashed a rom that was close to stock. When I did I lost LTE, and had very intermittent 3g. I just kinda dealt with it since I am on Wifi most of the time between work and home. Now, I want to fix it. I couldn't get my APNs to stick in CM12 when I flashed to it and was having the intermittent 3g, so I went back to unrooted stock and my LTE was back. Super! So I flashed back to CM12 and I'm right back to the same problem with 3g dropping and getting the ! on the bars. Not sure where to go from here.
Here is a list of the steps I took:
Start with AOSP rom > LTE
Flash back to stock > LTE
Flash to http://forum.xda-developers.com/note-2-sprint/development/rom-stock-oh3-rooted-deknoxed-deodexed-t3221123 > no LTE
Flash OH3 modem > no LTE
Flash to CM12.1 nightly > no LTE
Flash to stock > LTE
Flash to CM12.1 nightly > no LTE
In the past I've used plenty of CM and AOSP roms with no LTE issues. Granted, the issues may be unrelated, and it could just be something with the CM12 nightlies, but it all seems to stem back to when I flashed after coming from stock the first time. Anyone have any ideas what is going on?
What I would try is flash a radio file from http://forum.xda-developers.com/showthread.php?t=2139889 and see if that helps if not I would revert to stock via Odin. Hopefully this helps

I have the at&t e980.
Ever since I went to a AOSP ROM I do not have LTE.
I have the correct APN, I have LTE enabled in my toggles.
I just installed the 9/7 build of cm10.1, and tried to flash the e980 modem from the CM10.1 OP, and got stuck in a bootloop.
Any help would be much appreciated.

Try the PTA one, i had to use that APN to get LTE going on my E980 as well. both on cm10.1 roms and stock debloated rom.
weird you got stuck in a bootloop? ive flashed the modem many times with no issues. try and download the modem from the original TOT post and flash that one instead. thats the one that ive flashed and its worked every time.
also what recovery are you using? ive had heaps of issues with TWRP and switched to CWM and have had a lot less issues.
Hello all.
Is there another modem than the UVUAMDL version for the SGH-M919? Or a way to flash say, a i9505 modem to the M919?
The latest modem as of this writing is the UVUEMK2. Take a look at this thread here to see how to get the file and flash the modem.
Do not flash any other modems except the SGH-M919 modems. Flashing other modems will result in an inability of the phone to boot.

The thread you linked indicates to flash the UVUAMDL, and not the MK2.

No. There's no need to worry about Knox when it comes to flashing the modem. The only time you need to worry about Knox is if you flash the 4.3 stock recovery and ROM.
Much Appreciated

This totally worked. Thanks. No knox and new band. I'm still having a coverage issue however.

I'm also having issues with coverage. I came from a 4.2.2 ROM with MDL radio. Flashed darthstalker 4.3 ROM and I rarely got more than 1 bar of signal. So I flashed the Mk2 radio via Odin and still the same, one bar everywhere I go.
Any one else experience this?
Is 4.3 more accurately displaying my signal strength?
Or is this just normal?
My speeds are still pretty good with 1 bar....15mb/s down, and 2m/bs up

getting the same thing as well
did the flash to mk2, and, with all of you, i'm getting just 1 bar. didn't bother to check it since in my room, i tend to get at 2-3 bars; but, outside of that, the signal is usually quite strong.
another note, i'm using infamous alpha s4 12.04 rom, i'm not able to send mms or receive mms at all, period (while wi-fi is on). not sure if this is the same for all other 4.3 roms out there. i know of the data drops and what nots; but, haven't seen or read anything of not sending and receiving mms. usually, when i send mms, previously on infamous alpha s4 11r2 rom, it would go through just fine with no problem. the thing is, when sending mms it goes through 4G LTE since the 11r2 rom does not have wi-fi calling at all -- what this means is that even when on wi-fi the 4G LTE would come on the notification does it's sending and receiving animation and the mms would go through just perfect. but with the 4.3 12.04 rom it won't do that.
the only way to send mms, i found, was to disable wi-fi and wait for 4G LTE to kick in then send the mms. i don't like doing that, LOL. i like to be able to send mms even with wi-fi on without having to disable it (like with the 11r2 rom)
I have posted the solution to the signal problems you all are having in another thread. Go here and follow the instructions to resolve the issue.
I can not figure out how to get my radio to work with VirginROM v2.5.5. I have looked through the development thread for this rom, and have not found any info about people having no network connectivity. What I have found were posts about intermittent LTE issues, which have not solved my issue of connecting to tmobiles network.
This is what I have done:
1. I installed VirginROM 2.5.5 with an older version of CWM.
2. I updated CWM to 6.0.4.4 and installed the rom, which did not work.
3. A friend had a similar network issue with his Note 2 and a kit kat rom. He told me to reinstall the rom again after the initial install, but this did not solve my network connectivity issue.
4. I installed previous versions of virgin rom and then updated to 2.5.5, and I still cannot connect to tmobile.
You need to ODIN flash the mk2 modem.bin file. Search in XDA or the thread to find it.

You must flash the modem if you are having any issues otherwise it is pointless for anyone at XDA to help you out since this is a remedy to a widely known problem. Try it first and report back if it persists.
For the hell of it, check your APN settings.

I personally flashed the Mk2 modem via odin. wouldn't hurt to check the modem settings on your phone either.
go to dialer (after flashing your modem) *#*#4636#*#* and ensure that your on the appropriate settings

Flash TWRP recovery, then try installing a stock ROM. You can find flashables in the TWRP thread in the Development section I think.

I was wondering if anyone had any current Modem Drivers for 4.4 ? Every single 4.4 ROM I flash I get no service, no network connectivity I tried the latest modem drivers from here
http://www.rwilco12.com/downloads.php?dir=Files/Devices/Samsung Galaxy Note II (SPH-L900)/
Nothing seems to work. Any ideas ?
If you flashed the modem and still have no data service you need to re provision your phone. Try dialing ##72786# and see if that will do it. Afterwards go into settings and select the activate phone option down at the bottom. If non of that works you'll have to Odin a stock room and start over. That will definitely get you working again.
None of that works...I don't even get a signal for voice service...the phone has no connectivity whatsoever.
This all started after flashing to stock and starting over, I was having issues with 4g but now nothing...I managed to get a 4.2.2 carbon ROM working but that's it. No 4.4 ROM shows any signal at all.. Before flashing to stock I at least got 3g

You're using the recovery that every single 4.4 ROM tells you NOT to use in the OP. Use CWM or PhilZ and you shall be happy. TWRP has yielded broken radios in flashing 4.4 builds for 3 months now. Very well known issue.
Ohh damn I love twrp... OK I will certinally GI e that a shot.. Thanks
