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

Dial *#*#4636#*#* tap phone info and make sure your phone is in LTE/CDMA auto prl mode. Like this.

Is there a GS5 ROM for the Sprint GS4?
I've been looking around and all the other variants have some kind of GS5 ROM.
and if not is there a theme that I can flash to make my GS4 Look more like a GS5?

You can use sacs v4 ROM with s5 settings. It includes s5 icons and the s5 launcher plus s5 MMS.

None of Sac's roms V3 or V4 work on Sprint SPH-L720, tested by me. I was able to installed Version 3 and boot to it but Wi-Fi radio On/Off function does not work, Screen Mirroing does not work NFC does not work...useless. after all credit to Sac23 for his dedication and hard work to the community. hope next version is better and fixes all the bugs.

Could also be user error really. Did you make sure you are at the latest firmware? Follow step by step on how to install? Also recovery plays a big role now so yeah.

Yes, I have TWRP 2.7.1 installed, My phone is rooted using Towelroot. I have installed many rooms just to try, (this is my spare test phone) I was happy with results look and feel of only two (PhoeniX.ROM.V9.XXUGNF1.I9505.FIXED.by.tamirda) and (i9505 - S5 RivalStorm V2.1) but both only allow Radio/Modem for CDMA and are both international.
RivalStorm V2.1 seems to be the best room out of 5 or 6 I have tried, this room has every feature working and has the look and feel of the S5, that being said I will try your recommendation anyways and will post back my results, I did tried it before but I could not get it installed using TWRP, maybe I should use CWM instead.
But honestly I would be very happy to see RivalStorm V2.1 rom being domestic (US Carier...Any)

Sacs V4 works flawless on my L720. Do you have the 720T? Are you on the NAE build? if not, it is highly recommended you flash that version then follow the OP to the T.
Help me please guys. I have an AT&T Samsung Galaxy S 4 model SGH-I337. My manager helped me use Safe Strap to flash a Nexus ROM. I like the ROM alot but my internet is no longer 4g lte, it's now H plus. I have unlimited data but i downloaded an app to enable me to tether. My gathering no longer works unless i do it via Bluetooth. My Google chrome also force closes every time i open it. Usally i would just switch back to my stock touch wiz in this case. The problem is my manager put the stock rom on his sd card because i had no room on mine. I cannot get it back from him because he is on vacation. So i backed up this ROM because it works at least(I've found ways around those problems but they are very annoying.)
What i am asking is i wanna just flash a new rom that works( enables tethering, amazing on battery, preferably a google or android[i will take touch wiz as a last resort]) but I'm unsure of what i should search for because my phone model after the nexus ROM is GT-I9505G. Do i get a ROM for that our what? PLEASE HELPPP!!!!
Get a rom for the i337. not the i9505

You have to enable root access first. It's not enabled out of the box.
Navigate to "about phone" in settings and tap the build number a bunch of times util it says that you have enabled "developer options" then back out of "about phone" and goto "developer options", scroll down to "root access" and enable.

Ok good deal. Only other issue I'm having is mms doesn't work at all. Is there a fix for that? Thank you.

How to make cm12 jflteatt work on jfltecan
Hello, for some reason I am unable to get the rom to install via twrp. I have changed the device name in the updater script but still no luck. Any help? I've seen a lot of people doing the same thing and it worked for them.
Other people have posted this in the main thread but I'm getting signal drops with the 2/18 build using a clean flash on jflteatt. Switching the APN doesn't seem to help at all. Only happens a couple times a day. Other than that it seems to be working great!

Not sure if you found a solution yet--but try deleting all the APNs except for ATT phone and ATT lte. Then reboot. Select LTE (recommended) if not defaulted to already. And you should have improved signal after that.
I've never ran cm on my s4. I've run stock based, and GPE based. So this will most likely sound newb, even though I'm not : do I need to run loki-doki or any other type of Loki script after flashing cm, and before rebooting the phone?

Is it normal to get artifacts on black and weird color on this ROM?

No, that is automatic as long as your phone meets the bootloader requirements mentioned in the OP.
Help! NO Access to USB settings after Flash
I just Flashed 5.0.2 CM12 to my S4 i337m and I no longer can get access to my USB settings (*#0808 doesn't do anything) so the AWS enable I did yesterday is now gone and I can't get into the menu to try and do it again, Please can someone point me in the right direction! I was supposed to sign up with a new provider (Eastlink) tomorrow but I can't do it if I can re-enable AWS 1700 band. Thank you!

has anyone tried downgrading to MDB or MDL. I'm currently on OC3 and not sure if a downgrade would even work.
Good day, I am a noob, I installed Safetrap in Android 4.4.4, I can install this ROM? Or as I can install? Sorry for my bad English.
Hi, I'm a noob. I want to install this ROM on my Galaxy S4 AT & T but do not know how. Someone tells me I need to install Cyanogenmod? Sorry for my bad English.
Updated the phone to 5.0.1 on a Touchwiz rom without knowing about the problem with xposed and custom recovery. Is there anyway to downgrade this to the MDL or MDB bootloader?
SGH-i337m and Cyanogenmod 12.1
Hi. I recently flashed my Samsung S4 to Cyanogenmod 12.1 using 12.1-20150426-NIGHTLY-jfltexx. Although it is working fine overall, I am having trouble maintaining Bluetooth connectivity. After reboot, the connectivity is ok for about an hour and then drops. And when it drops, it doesn't turn back on again.
Is there any way to fix this problem?
Also, is there a newer update that is compatible with SGH-i337m? I have received the latest updates of nightlies on my phone, but when I go to install them, the installation aborts.
Lose SD Card functionality with 5.1
I flashed the 12.1 05062015 nightly and have been experiencing intermittent access problems with my SD Card (external 64MB). Checking Storage, the SD Card sometimes disappears but the menu still shows an Unmount SD Card option, suggesting that the OS knows the card is in place. And sometimes unmounting followed by mounting brings the SD Card back to life. Other times, however, unmounting does nothing and a restart is required to enable functionality.
I also tried to move some apps from the phone to the sd card in Apps and while these moves appeared successful (i.e., the button for "move to phone" was highlighted and the move to sd card not highlighted), Root Explorer now cannot locate them and the moved apps no longer appear in the Apps listing.
The SD Card worked perfectly with KitKat so I don't believe the sd card is the issue. A Google search shows numerous concerns involving Lollipop and sd cards but none of the solutions have worked.
Wondered if anyone else with an AT&T Galaxy S4 has had this problem and if there is a solution you can point me to.
Thanks.

Reflash the NB1 tar file in ODIN and see if it works then. You can find it in the general section, either search for the thread or find it in the [INDEX] thread.

started working for 5 hours then returned same issue...
I used Odin to root it using Nc1 Then finished with J4 ...
im guessing this must be a problem many are facing. a friend of mine gave me a an S4 logic board i337m variant and it has the same issue i have tried everything from flashing new roms flashing stock frimwares tried different kernels modems nothing seems to work. i second this post to see if we can find a solution. my phone is a I337m and have flashed GOLDENEYE to get the lollipop experience a month before the official Lollipop came out for the canadien variants and i have not had any problems i was wondering if i made a backup with trwp and see if this might fix this problems and if it does i can upload my exact backup to help other. but i was wondering if a dev can help me out and see if this could be a possible solution.
In the same boat aswell
I gave my phone to someone to update it to lollipop GPE about 2 months ago.... wifi would work but my data connection would cut out the minute the screen shut off.... after contemplating going back to the guy.... i downgraded to hyperdrive kitkat rom witch gave me better connectivity but no wifi... I ve been living with that for up until now until I decided enough is enough and flashed the stock lollipop rom yesterday. still no wifi. whats even more frustrating is I cant find the file path thats being mentioned so commonly as the solution.... and yes I am rooted. Also wifi was working no problem before I updated..

Well last night I went from 4.4.4 back to 4.4.2 to see if thus would solve the wifi and blue tooth head ache. It all started working just fine and did all the way up till tonight then back to not working. I then resulted to cleaning the Wifi prongs on the phone and it worked again for few hours. Now the weird thing happens I put it back into the phone case and just from snapping it in it stop working AGAIN. I restarted the phone once taken out of the case and it was working so I think I'm at a conclusion it's a mechanical issue not software. Maybe the wifi circuit us faulty
I've had lots if Galaxy and worked on a few friends but this wifi and blue tooth crap us unbearable.
My Bluetooth is fine. My wifi broke after downgrading to kit kat so I know it works It just seems the wifi files are corrupted or missing. I'm sure it's simple I'm just not savvy enough to implement it
