[Q] Terrible data speeds for no reason - T-Mobile Samsung Galaxy S 4

I'm currently running BlueLightning-20140410-jflte. I just tried updating to the new modem, so my Baseband is M919UVUFNB4 (from MK2).
My kernel is 3.4.82-ChronicKernel, and I have done some minor modifications to the ROM, mostly just removing bloatware.
Up until last week, I got incredible LTE speeds, from 30-50Mbps. Now, I am getting .5Mbps to 5Mbps, maximum. The average is around 3Mbps.
Called T-Mobile and they did troubleshooting. Confirmed that I am receiving the proper signal from the towers and everything.
Beyond changing my hosts file to block ads, I have made no real changes to this ROM, my kernel, or anything beyond updating my modem.
Can anyone point me in the right direction? I don't want to have to switch phone carriers just because I am no longer getting the speed that I should. Any help is greatly appreciated.

My previous modem is when the problem started. That's why I updated it in the first place.

Flash NH7 modem or try a different ROM.. If those don't work, flash back to stock and see if speeds go back to normal

Looking for info on flashing I747M (CANADIAN) to AT&T modems

tried it once without any luck. going back to stock telus ROM at the moment.
has anybody had any success flashing an AT&T modem onto an i747M?
i am using the telus variant
edit: reason i wanted to do this was b/c i was getting some consistent signal drops. after having to go stock telus -> CM10 nightly (8/20), i'll see if i'm still getting any drops. that was the reason i wanted to use an AT&T modem, but if the issue doesn't come back i'll withdraw my inquiry

I'm using 8/18 and I'm not having too many issues. CM has been my daily driver for 2 weeks. I'm on telus as well. I haven't tested LTE, but once I'm back at school I'll figure it out and make sure everythings working smoothly.

CM10 8/20 nightly works great, i'm not getting any of those signal drops i had from before. maybe the phone just needed a full wipe. anyway, i'm not too curious about flashing an AT&T modem anymore. it would be nice to have a choice of modems, but that's definitely the lowest on my list now that there aren't any drops
I am using the LLE8 stock Bell modem even though my firmware is the latest ATT LH1: I did attempt to flash the full LH1 leak including the modem, but lost my IMEI in the process. Seems the modems do not play nice across different carriers, even when the phone is an I747 -- the developers then removed the modem out of the firmware package and the LH1 release installed without any issues. So my experience is that the ROMs are quite compatible, ATT to Canadian users, the source code for the kernel is standard across all SG3 phones according to the developers and the experience of people using kernels irrespective of carrier designation BUT the modem (baseband) does not appear to be cross-carrier friendly. So until a fix is developed and/or one of the Canadian carriers updates their firmware, we are stuck with LLE8 or its equivalent..

yep. i came to the exact same conclusion. i'm not too worried about it; phone takes a few seconds to hop on to LTE where i am, but no big deal

Modem Question

Does the modem affect the LTE radio? I am still on MDL bootloader and I installed the NB4 modem. Curious if I will see the huge increase in speeds with LTE like everyone else.

I'm on T-mobile and installed it....
I only got EDGE! Lots of Bars, Much more than I got before, but never saw LTE nor 4G!
When I tried to re-flash the MDL modem which I had before, all hell broke loose.
I ended up reverting to stock, rooting it again, installing CWN recovery, and then getting my nandroid restored to 1 day ago....
Dunno if the modem file I got was farkeled or why it was not working right....
I downloaded a different modem.bin and NON-HLOS.bin and flashed it. To my great surprise, it improved all my reception quite a lot! more bars where I NEVER saw that many, and no dropped calls since the flashing of it.
Have not tested speed in detail, but rough test showed more speed overall....

I wasn't sure if the modem was GSM only or LTE included.
have you noticed a bump in speeds? I noticed 1-2 more bars in LTE and 3G, but speeds don't seem/feel faster. People in the NB4 thread report faster speeds.

[Q] Updating to NE6 Firmware

I'm on a Stock Rooted with Custom Recovery. how Can I update the firmware?

You need to download and Odin flash the official stock N900T NE6 firmware.
Here is the direct fast download link for it:
http://www.androidfilehost.com/?fid=23501681358537528
The zip file also contains Odin, CF-Autoroot and TWRP 2.7.0.1 recovery.
Unzip the file into a new folder in windows desktop.
Be sure to go into recovery before Odin flashing NE6 and do a factory data reset
and a full wipe. Then Odin flash the TAR/MD5 firmware.
After successful odin flash, put the phone into download mode again and
flash cf-autoroot and the TWRP 2.7.0.1 tar files.
If you want more information and or instructions here is the link:

Ok So I did all the above and it worked good. I have all the New "Features". However, Baseband is still NB4 while the Build Version is NE6. Shall i try to fix this or leave well enough alone?

run triangle away v3.26.apk from chainfire, when you apply the info. it will shut down, power off, then boot to bootloader and flash firmware, that was the easiest way for the modem, baseband to stick....

Fix it! I think the baseband is partly to blame for the the data drops in nb4. And I'm getting way better battery life as well. To get the new baseband to stick download Triangle Away then reflash in Odin. Worked for me. Id recommend you wipe your data too. http://forum.xda-developers.com/galaxy-s2/orig-development/2013-10-04-triangleaway-v3-10-t1494114

Use Triangle Away to reset your flash counter and make it official. Then flash NE6 with Odin/Mobile Odin to get latest baseband.

do i need to be on stock nb4 kernel then use triangle away or does using triangle away good enough to start the process?
Just did this today, you need to be on a stock samsung kernel for triangle away the warning is VERY clear in the app. Personally, when a developer says "do it this way, or you will have a problem" I take their advice.
Read carefully and follow ALL of the instructions very carefully as well.
There are at least two different threads covering how to flash this. One has "stock ODEX" {{ http://forum.xda-developers.com/showthread.php?t=2713354 }}, the other has "stock Deodexed" {{ http://forum.xda-developers.com/showthread.php?t=2761451 }}
Good luck
There is "NO" way to update officially to NE6 if you have rooted, modded, used a custom recovery in the past on you Note 3.
If you have tripped knox in any way, you will already have the bootloader you need to be on, and can flash the new stock rom from the forum.
If you have not tripped knox, have no custom recovery, have never done anything to your phone, then you are free to get the update as TMO pushes it out.

I am looking for a thread that has just the modem files I need to flash to either update my modem or flash the previous modem if I have data issues.
I have searched and I know the thread exists (at least for the older modems) but for the life of me I can't find it -
Any help? Do you have the Note 3 TMOBILE modem bin's you can give me (or provide me a link? For the latest update and in the event there are issues for me to return to the previous version?
Any help is appreciated!

It does exist, but just flashing the modem alone won't solve your problem. I tried it yesterday. Seems to need something else. I flashed just modern and left the rest of phone the same. Still having to toggle every so often with the ne6 modem in here.

I did find an older modem file that I was able to flash and my speeds returned to their previous state - I have given up flashing the updated modem until I can figure out what I need to flash to make it work better. RIght now, if I flash the one modem file I see available, my speeds are bad - maybe I need to odin the full stock tar - and then re-root ? I don't know, I will go back to my S5 for now and will play around with this until i figure it out or someone gives me the help I need - thanks for your help.

Good luck. I'm switching to at&t this next week. Just paid off my eip. I just want functionality. Going to hit up an aosp ROM later today to compare. When I cone back to touch wiz maybe *all new roms will be updated to ne6. It's weird though because I used to not have any issues, then a week ago I couldn't connect to anything on lte. Was hoping it was just a modem issue, but probably needs kernel as well.

I stopped buying ATT Phones after my S4 and have been very happy using TMOBILE phones on ATT network. Speeds are awesome - and having the ability to easily root and flash makes it all worthwhile.
Good Luck!

That's what I told the t-mobile rep the other day. Phones will be bought through t mobile, but as far as reliability I'm going to have to go with att. I would have stayed with t mobile if they didn't cancel my companies discount program. It was 15%, but my company decided to no longer offer the program. With att I will have a 25% and no contract. Can't really beat it.

I also tried TMOBILE services - I could not get any signal strength inside my home so the only way to make calls was to use WIFI Calling - (probably why they built that feature in the first place)
Then the data speeds were very slow - the fastest speed I could get around town was around 6mps - but on ATT I get consistent speeds over 20MBS and soemtimes 35MBS and higher - download speeds have been also very good -
I have seen others praise TMOBILE for the high speeds they get - so maybe things are better in their market? Don't know - just that they suck where i live...

In my area they are great if outdoors, but don't cover the whole city. I also have zero indoor penetration. They have bought a ton of 700 MHz spectrum off of Verizon, so that portion should get better soon.
Their LTE is fast where I live if you can get it. I got 35 Mbps the other day. But again, I have to travel outside of the city on jobs and am quite frequently without Wi-Fi or service.... So the jump is going to be made. I use my personal cell phone for work, and if I don't have signal, that is money lost...

Bad/no reception on T999L, need help/suggestions

These issues started with the upgrade to latest T-Mobile 4.3 software pack at the end of November. Phone operated perfectly before then. After the update, the phone would periodically not receive/place calls/texts/use data. The issue kept worsening daily. It is not related to the SIM card or location, as the card has been replaced and tested in an alternate phone where it performs perfectly.
The T999L was then consequently rooted, KNOX flagged (it's already past warranty, Samsung wouldn't give a rat's ass about it), flashed to CM11 M12 and later a variety of modems was tried. Same issues persisted. Restored to stock 4.1.2, same issues. Did 3 updates OTA to get to latest 4.3, same issues.
Messed around with 4636 menu, 2263 menu, etc. Some changes had a temporary result but nothing permanent. Calls to the phone are redirected to voicemail. When placing a call, it takes 5-10 seconds to either place it or disconnect it (as it can't connect to the network, I guess?). The bars on the phone show 3-4 bars typically, but the phone is rarely able to acquire a data connection. Again, this is not the case with other phones the SIM is tried on.
Any suggestions? I've spent probably close to 10 hours researching this and trying everything out and I am absolutely stumped. This is my mom's phone and a replacement Alcatel OneTouch Fierce 2 just "doesn't look nice", so I'm getting a fair bit of *****ing for trying to help solve this, even though it's not my fault. Would appreciate some help before Christmas.

I'd say so. Used this thread: http://forum.xda-developers.com/showthread.php?t=1880987 and flashed the 4.3 basebands for T999L and T999N, total of 3. I'm thinking this is something to do with the 4.3 bootloader or basebands... any methods to go back to 4.1.2 without a brick?

If you have a T999L stick to the designated T999L modems and nothing else, or you may damage the device. If you have a 4.3 bootloader there is no way back. Have you tried to use ODIN to flash the latest NF4 firmware for your T999L and then do a factory reset using the stock recovery? I posted NF4's link in this post. Good luck.

Downloading right now, and will test. Pretty sure this is the firmware update after which this problem started occurring.
Any other ideas for what might be affecting this besides baseband? I have a feeling something else might be causing this. I'm not familiar with Samsung partitions though and what is flashed by OTA/Odin.

Well, OTA updates can sometimes fail, that's why I gave you the ODIN firmware link. It's the best help I can offer.

bandwidth connectivity issue, (installing new radio possible fix)

i just encountered this issue the last few days and continues even after installing a new rom. im having trouble downloading files online or apps from the play store, its almost like the connection keeps getting disconnected and reconnected. im also having a problem playing a small online game called spades that worked fine a few days ago. its a card game so is not graphic intensive or take up alot of bandwidth.
another issue that ive just dealt with for months is rarely getting LTE data even though i should be getting according to the coverage map. im usually in wifi so it doesnt bother me too much but it got me thinking maybe i should look into installing another radio/modem which could possibly fix these issues. my current baseband is UCUFNJ2
You're running the latest modem for this phone, so there's nothing newer available. People have hard bricked the i747 on newer firmwares getting the bootloader and modem unmatched, so you have to be careful. We used to think the bootloader couldn't be downgraded at all post Knox, but it turns out you can downgrade as long as you don't go back a major version. There's a set of odin flashable files available. That's the only confirmed safe way I know to downgrade NJ2. Since you're already on NJ2, you have to stick with a 4.4.2 modem.
Safest thing to do, if you want to try out a different modem and just give the phone a fresh start would be odin back to stock NE4 4.4.2 using the files you can get from here.
From there you can test drive NE4 and see if it works any better. If you leave it stock it should offer to OTA to NJ1 and then back to NJ2 too, letting you fairly safely try out all the modems left available to you.
