No LTE after flashing cm 10.1 - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I've noticed that my phone is no longer able to connect to the LTE towers that are available to me.
I also noticed that my phone uses "1x" when LTE towers are available (so that's fun)
3g and 2g work just fine but LTE refuses to work
Here is what I've tried:
Reinstall the rom
Do a clean install of the rom
Play around with the apn and network mode
Restart my phone
Update the firmware
Update to the latest nightly
What I'm going to do:
Install the stock rom
And/or install the Google play edition rom
Any ideas why LTE isn't working? And does it work on anyone else's phone?

I remember when i would flash CM10 and any CM10 based roms on my sprint Note 2 LTE wouldnt work it was broke on CM10 based roms well any non TW roms one thing that sometimes would fix the issue is reflashing a TW rom updating prl and profile then going right to cm10 but it would lose lte after a reboot for me still.

Also try a different kernel. Works for me when I only have 3g in an LTE area

Best rom for Rogers s3

I have a rogers s3 i rooted and installed recovery I just want to know if any other people with rogers phone installed any of the custom roms and if so what ones ?
Thx
I have tried the Diet ICS...it works pretty smooth...
but there are few things missing... LTE toggle
I am trying to find themes with 1% battery that work on this rom..does anyone know??
I find that best rom for Rogers or Bell for that matter is actually stock Telus right now. No Rogers bloatware, no fake 4G but like international proper h+, no nfc on symbol cramping my already cramped status bar. Picking lte or hspa or gsm still available in settings and lte only or wcdma only or gsm only still available from *#2263# menu.
Sent from my SGH-I747M
Rooted Stock Rogers with all the Samsung and Rogers stuff frozen with tb (gains some free ram). Add in cwm for a recovery and mobile ODIN for tweaking.
Looking forward to cm9 and especially jelly beans based roms.

T-Mobile USA and Older radios problem!

We all know that after updating to 4.2.2 via OTA and the new radio .48 the LTE is disabled.Some users have flashed older radios .27 and .33 and were successful enabling LTE again on our devices! However most of T-Mobile USA users(including myself) are NOT able to get older radios work on stock rooted 4.2.2! After flashing older radios you have usable data connection but no audio in call! I`m not able to hear anything when connected to a call! So far I have tried:
1.Flashing .27 radio and installing the RIL for 4.2.1= no audio in call
2. Flashing .33 radio and installing the RIL for 4.2.1= no audio in call
If anyone has been successful getting it work on T-Mobile USA, please share your steps and methods to achieve that!
Thanks

I had the same issue. .33 screwed up my phone. I couldn't hear anything from the earpiece. Unfortunately I found the reason why and .48 fixed the problem. Anyways, which city do you live in that has LTE from T-Mobile? There are very very few LTE coverage in USA from t mobile. It would be pointless to enable lte if you do not live in a lte coverage area. I don't know why .33 won't work on 4.2.1. It should work.

I live in Boston. I don`t know if LTE is live yet, but I just wanted to try and see. But older radios don`t work....Have you tried older radios+custom roms?

I don't think it would matter if the phone was running on a custom rom with a old baseband. Basebands, bootloaders, kernels and roms are kinda like their own thing, y'know.
Same thing happened to me, had to go back to .48

That's not exactly right though... The kernel controls the radio(baseband)

Yeah!!! What's the deal with that I can't get .33 to work on stock rooted 4.2.2 I'm also from the Boston area.

If you want a solid ROM that works with the old radio use CM10.1 Nightlies . It works great with both radios.

Yeah, I guess we have to jump to custom roms whenever LTE is live in Boston....
bump! Maybe a Dev can give us some more info on that matter???
I've seen the LTE APN setup in the switch as fast.Tmobile.com . I'm thinking you need that for it to work once it's turned on
Flashed .33 too and had no sound. Had to flash back 48
On Tmobile USA too

I flashed Dark Jelly n4 with the .33 radio and it works fine coming from the .48 on t-mobile. (I was on stock originally then got the update)
No problem here but i am using the franco kernel if it matters.

Every time I flash a custom rom I lose 3g.

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.

Anybody get 4G LTE running on 4.4?

Running a Cyanogenmod 11 Rom and loving 4.4. For some reason though even though I had it unlocked in my original 10.2, and I have the option to access fast.tmobile.com checked off in settings under 4G LTE (and have even gone so far as to reflash the hybrid modem) I have no access to it.
Anyone else having this issue?
no, ran fine on lte after the first second of upgrading to 4.4. a cm issue maybe?
LTE works for me in Purity ROM 4.4. You do hard to reflash the modem. There are also new modems to download based on the base band 97.
Sent from my Nexus 7
Working fine using the .84/33 hybrid. You need the hybrid modem and a build.prop modification. You can then switch on lte from the phone menu at *#*#4636#*#* by choosing LTE/GSM/CDMA auto.

Successful MMS and 4G LTE with Cyanogenmod on Sprint S4?

Has anyone with a Sprint Galaxy S4 found a stable combo of any Cyanogenmod build and modem that allows for: 1. Consistently successful MMS sending and receiving AND 2. Stable 4G LTE that hands off well between it and both 3G and WiFi?
In the alternative, any specific tweaks to APN settings to allow for items 1 and 2 above?
If you have found such a successful combination, please post here, and please be as detailed as possible (CM build, baseband version, specific APN settings, etc) , thanks!!!
Cheers,

I hear you on this. I've had to disable LTE in order to get the phone to work properly, since the Phone would become non-operational after LTE signal would drop out.

I was on CM11 12/22 and Beanstalk 4.3 and used this..

Now I'm on ProBam and all seems to work well. My MMS on WiFi is sporadic at best but on MMs and LTE/3G I'm ok.
Hope it works for you.

So how well does your LTE hand-off to 3g? I have to go into airplane mode in order to get 3g working after leaving LTE, (even though the phone claims to be connected to 3g after dropping off of LTE)

Thank you very much, I'll try the latest nightlies of CM11. They must be working better than CM10 as far as MMS & LTE is concerned. One last question: which type (and version) of recovery did you use for your CM11 flash? (TWRP, CWM, etc.) Thanks again!

I'm on the latest CM11 nightly (1/10/14). 4G works fine for me, but mms is very spotty. It works right after I boot my phone, then it stops working. I don't know why it happens, but I receieve MMS messages right when the phone boots, then it stops working. My modem is MF9. I'm not sure what exactly is causing this problem. Would flashing a new modem help? If so, how would I do it?
Update
Yes, I would recommend that you try flashing the MK2 modem.
All is working well for me now: MMS sending & receiving, good hand-off between 1X, 3G, 4G LTE, and WIFI, etc.
I'm now running the latest CM 11 nightly (1/13/14) with the stock MK2 modem, and I'm using CWM 6.0.4.4 as my recovery.
FYI:
Just for kicks, I went back to the last (stable) version of CM 10 to see if MMS played any better with the MK2 modem (since I would still prefer to stay on CM 10; I just like JB 4.3 better), but unfortunately I encountered the exact same results that had caused me to start this thread in the first place: bad MMS functionality, bad hand-off between 3G, 4G & WIFI. So... I guess on 4.4 (CM 11) I shall remain....
Thanks again to everyone for their contribution(s) to this thread, you all have been very helpful!

You can get the MK2 Modem from here: https://www.androidfilehost.com/?fid=23252070760974263
The proper MD5 sum for it is: 39b0b32a8ee338543fdaa91ab2774f79
This is a flashable TAR, so you can just use Odin to flash it from download mode.
Cheers!

Thanks for help I flashed the new modem and it didn't do anything. I started apps from startup and discovered that AdBlock Plus blocks mms because it monitors port 80, the same port MMS is sent on. I fixed my problem by uninstalling ABP and I use AdAway as a replacement.
sorry for asking this guys but does the CM11 lets you SIM UNLOCK the phone as well im asking this because thats what im focus on many thanks
im just new in this new era world....god bless y'all
