I'm currently running CM's latest stable build (10.2.0) and MJA. After flashing CM, I've noticed that I've lost some 4G coverage. I'm curious if flashing the MK2 firmware would help this issue or hurt it - don't know if CM 10.2 is compatible - or if I need to find a way to update my PRL manually since its obviously not a Sense ROM.
modems are compatible with ALL roms.

The option for LTE in phone information was disabled in 4.2.2
Is there anyone working on a stock 4.2.2 rom with LTE Enabled?
Me and a few of my friends are looking for this for our phones
otherwise were forced to downgrading back to 4.2.1
Sorry I didnt notice where I was posting this, hopefully this is moved to >>> Q&A, Help & Troubleshooting
Also would flashing the radio from 4.2.1 enable it?
i think it is more of a radio thing. if you use either .27 or .33 radios then you can access the LTE. i did have a problem with paranoidandroid on tmobile where both of those radios would work and give me LTE but i lost audio in call. i am now running trailblazerz11 rom with .27 radio and i have audio in call and LTE.

Just flash older version of radio image on any ROM (stock works too I believe) via fastboot and you should be good to go

I have no idea why this seems only to be happening to my phone... I get zero 4g despite my phone showing 4g. I have updated profile and prl in tw... I have tried twrp and cwm. I just can't get 4g on a aosp ROM. Any help would be appreciated. Both screen shots show speed tests in the same place while I was at work.
It's been known that aosp in Many cases causes this. My last phone epic 4g touch was the same way. Flash stock rom and data speeds back to normal

I have had issues with aosp when I would dirty flash. I'm currently running Carbon and 4g is running great. Just try a clean install. Could also consider that we are mostly on nightlys and unofficial releases. No telling as of yet but I'm getting pretty good speeds on Carbon

I always do a full wipe before I flash a aosp ROM.. I seem to be the only one on the forums having this issue. the only thing I can think of is a bad modem. Haven't found a flashable modem so I may unroot odin stock and reroot and see what that gets me. I only run aosp roms on all my phones...this is killing me

From what I understand we can't flash modems yet. Are you on MDL or MDC? I have had issues with the modem on TW after unrooting on MDL, but they were fixed when I reinstalled the update from Sprint.
Not really sure how the radios interact with AOSP, but could have something to do with the differences between the update.
Every time I flash a rom I lose 3g. I've tried all the touch wiz roms like wanam and pyrana and everything works except 3g. It goes down to 1x. I still have data just not the 3g speed. Any ideas?

hi to help you out here goes,
its more than likely that when your flashing roms this changes your baseband (ie modem/radio)
to fix this you will need to remember what the original baseband was prior to flashing custom roms (ie when it was stock rom)
if you cant remember try phoning your providor who should be able to tell you.
then simply find the corresponding modem here on xda and wheather its a cwm file (.zip) or odin file (.tar.md5) flash that and 3g should be restored.
however which network are you on and do you have a sg4 (reason being is that its an lte phone built for faster web speed so if your seeing a (dc or 4g) all is well.
also you may have your settings incorrect in wireless and network/more/mobile networks
Yeah I'm on the sprint network and have the 9505. So it's capable of 4g lte but that's not available here yet. It is in Detroit and when I've been closer to there I've seen it switch to 4g but it's always on 3g down here in Ohio. I think it's kernel related as I was messing around with the stock rom and different mods like transparent status bar and different toggle icons and I figured I might as well flash wanams new version of the Adam kernel 1.4 and I lost my data connection. On the stock rom. I restoredit and it was back.

I'm posting this here because I don't have enough credits to post in the development forum. I've been installing various custom roms on my Sprint Galaxy S4 (Carbon, Sacs, to name a few). The ROMs seem to be working fine except for the fact that the phone will not connect over LTE, only 3G. I've tried all sorts of kernel/ROM combinations, profile updates, PRL updates, but when I restore to my MF9 backup, 4G comes back.
Can anyone confirm that it's possible to connect to LTE with a custom ROM.
I am running Sacs v7.2. I only have patches of 4G where I live, but when I get into one of those areas, it works fine.

Thanks. That's interesting. I was most recently trying Sacs. I started with a stock MF9. I rooted it with CF auto, installed TWRP 2.6.3.0, and flashed Sacs. Right then, 4G stopped.
I heard there may be problems with TWRP 2.6.3.0.

I'm wondering if it's due to the fact that Sprint is just turning on 4G around here. Even with it stock, 4G is on and off all day. I just noticed that.

more than likely.....it was real spotty when they started building towers here as well
That was the problem. Working with 7.2.
It's working on 8.0 as well.
Anyone seeing a problem with Bluetooth LE in Sacs v8.0?
Hello,
I have just updated my Sprint Galaxy S4 to Gummy Rom KitKat 4.4 but I seem to be having signal issues. Is there a way to update my Profile and PRL to the latest without manually doing it. I can find the updater within the interface of Gummy.
Thank you!!

I have found that updating to the latest PRL and profile on the stock ROM BEFORE installing a custom rom has help me avoid some signal issues. I may be the long way, but that's what works for me. sorry if that's no the answer you were looking for.
There is no way to update profile or PRL in anything but a TouchWiz rom.
