Ok im new to this site but not to new to root and flashing. Ok so here is what I have done. I rooted my S4 when i got it and everything was fine. Then when the 4.2.2 came out I updated it straight from my rooted s4. After so my 4G LTE for some reason has been cut in half. I always get a speed of 20 to 35 mb download at my house but after update I can only get up to 10mb. I tried last night to flash back to previous build or firmware but did not have any luck. So I flashed to stock firmware that the update came with (ME7) and then rooted it again but I still cant get speeds over 10 or 11 mb. I have another LTE phone side by side and the other gets over 20mb. Is there anything like flashing modem or anything else I can do to get my S4 to preform as it did before the update.

Backstory: Just got my replacement S4 (warranty) and luckily it still had the MDK bootloader. I was able to root and install CWM without any issues (having the SIM pulled the entire time). I am very anxious about getting my phone setup I d/l CM11 and the MK2 modem. This is where the trouble started.
I flashed the modem.bin using Odin 3.07 and it passed. Then I flashed CM11 and had no issues. Stayed on WiFi to get everything loaded and when I turned off WiFi, I noticed that I can only get 3g service. This is in a 4g dense area that I have never had a problem getting 4g before. I thought it was CM11 so I revert back to stock with root, but still no 4g. Now I am getting frustrated and put the stock modem back using Odin (this time it was the tar.md5 file) and still no 4g.
Final Point: So I don't know what I am doing wrong. I can get 2g/3g/WiFi, but no 4g. Still have the IMEI in the phone status.
All help is appreciated since I can't find anything topic to help with my situation.
Thanks.

Same thing happened to me when I got a new s4. Had to get a new sim card. There free at Verizon corporate stores and something like $10 at retail stores.

Double check your APN settings. If everything is good there I'd get a new SIM card.

Background:
I was previously rooted and even after disabling root I could not do the OTA (it kept giving me a status error 7). After researching I decided to use ODIN to try and restore to a stock ROM for the upgrade.
I initially tried to use CI605_I605VRLJB_I605VRALJB_CL414933_HWID04_HW_Rev0406_low_ship_user as the firmware, but it caused my device to go into a firmware upgrade error.
I then used I605VRUEMJ9_I605VZWEMJ9_I605VRUEMJ9_HOME which got me back to stock 4.2, I OTA'd to 4.3, and using a previously downloaded OTA copy of 4.4.2 I booted into recovery mode and manually installed the OTA.
The Problem:
Since going to 4.4.2 (and I noticed it in 4.3) the Google Play store seems to load EXTREMELY slowly. I have Frontier FiOS and speed testing the connection shows a minimum of 25/11.36 Mbps for my connection. 4G does not appear to work so well either.
Could I have messed something up? I do not know why my stuff is working so slowly...
Device: Galaxy S3
ROM: Slimkat
ROM version: Slim-4.4.4.build.6-OFFICIAL-5242
Build: slim_d2lte-userdebug 4.4.4 KTU84P 5242 test-keys
Kernel: 3.4.95-cyanogenmod-gd56ed95
I purchased my S3 in April of last year (4.1 Jellybean), and at the time the wifi worked perfectly. After the first (or second?) OTA that was pushed to my device, my wifi started acting up. It would cut out and I would have to cycle the wifi off and back on in hopes it would work again. I have been patient hoping they would push an OTA that would finally fix it. A year or so and a few OTA (I don't recall how many, or which versions) later and it still doesn't work properly, so I decided to finally try a custom rom to see if it would solve the issue. The last stock version of android I was using was the 4.4.2 OTA.
I rooted my device using towelroot, flashed CWM Recovery (CWM_6.0.4.7_Non-Touch_GT-I9300) using ODIN 3.04, then proceeded to flash the Slimkat rom listed above using CWM recovery. The wifi seems to be better, but it still cuts out and is unresponsive even though it says I have full wifi signal. A wifi cycle seems to fix it temporarily, but I'd like to solve this issue.
So as far as I can tell the last working modem I had was stock 4.1 or so. So I guess my question is, can I flash previous modems to try to get a working one with this rom? I have tried using WIFI Fixer from play store, and even with full signal on WIFI I get signal poor, signal hop scan messages spammed. Any and all help would be greatly appreciated!
Ok, I have a i605 Verizon. I've had his phone for a while. Rooted it 5 min in the door 3 years ago. Flashforward to today. Just noticed that baseband, build and everything is wonky. Anyways, decided to start over and re-root today and having some issues. Also keep in mind i've moved to StraightTalk with the AT&T sim. It's been working for the last year on ST by using N7105 and i317 ROMS. Haven't really done anything to it. But noticing on the About Screen, i'm showing a lot of different things (Attached)..
Android Version 4.1.1
Baseband version: I605VRAMC3
Build number: JRO03C.I605VRALJB
This is of course a fresh reload into root66 vzw stock rom. I do have the Stock Kies MC3 ROM but Odin errors everytime I try to use it.
What is going on, how do I get things to line up so i don't brick my device.
I've tried changing the bootloader but it keeps erroring everytime
Thanks!
Ok, flashed the MC3 stock rom thru odin (forgot about the pit file) it's installed fine.. going to try from here
So, I am on the nightly CM12.1 build for the hltespr Note 3 (N900P). This is the one.
I can't seem to find anyone else experiencing this exact issue and it hasn't been posted recently. I have no 4G/LTE service. I have toggled every setting both in the regular settings and under the *#*#4636#*#* settings and nothing seems to work. I was able to flash a stock rom and got LTE service immediately but again got nothing but 3G when I flashed CM12.1 back.
Any suggestions would be greatly appreciated.
Edit: Just wiped data, delvik, cache, etc and loaded the latest nightly fresh and I still get no LTE.
Same here i only get 3g on any room i tink it is something wrong with our modem im using the last kernel h1 let me know if u found the answer
Same here. I flashed Phronesis N5 v6.5 (with the CSC set to SPR and updated my apns-config.xml to a copy from my wife's identical phone) and have only been able to get 3G. I have reverted back to stock and 4G was up and running. This is my headache right now. We need to pull our heads together and get this figured out. My baseband is OK2 right now. I was thinking maybe upgrading to the PH1 would help. It's just odd it works fine with stock.
I just realized wilder90 said he has PH1 running and it's not working. Maybe I will still try it.
*Update- I rolled back to stock and upgraded firmware to PH1. My build says LRX21V.N900PVPUEPH1 but baseband and software still say N900PVPUEOK2. I have 4G working. Do I have to update baseband/software another way?
*Update- I downloaded PH1 from sammobile.com and flashed the update through Odin. Now all says PH1. 4G still working great. I am going to flash Phronesis again and see if there is a change.
*Update- I changed my mind and went with "Sprint Users Rejoice!! MM 6.0.1 Darklord Modded V5 By JCordero31 N5N7 APPS 1/22/17"
I have 4G/LTE working. It doesn't have really any customization available but it works and it's new.
