[T Mobile] Signal is cutting out, someone suggested updating bootloader / radio? How? - Galaxy S 5 Q&A, Help & Troubleshooting

I have an S5 from T-Mobile, it is several months old. It is currently using Cyanogenmod 12.1 Nightly from July 4.
I updated to the October 21 Nightly a few days ago, and started seeing an issue, where the mobile signal cuts out after a while (usually after I wake up the phone after a long time of inactivity, such as sleeping). I will see a mobile signal, but there is an exclamation point next to it. LTE data won't work. MMS won't work. I don't know if SMS or Phone Calls will work, but I suspect not.
I asked on Reddit, and someone suggested that my phone might need a Bootloader / Radio update? Someone made the following suggestion:
"Many Samsung devices require a bootloader/radio update to run the latest CyanogenMod versions. You need to make sure it is both the bootloader and radio, becasue many update packages will do one or the other. You can find the flashable zips on the xda forums. "​
In the mean time, I have downgraded back to an old July 4 Nightly, but it looks like the problem is now persisting. So, finding a solution is now more urgent.
Does anyone know how to update the Bootloader / Radio for my T-Mobile S5? Directions / Links would be helpful... :-s Kinda newb at this.
Or, if you could recommend a ROM that you prefer over CM, that would be welcome info as well. I do like CM, but you know what they say, the grass is always greener. Plus, I think everyone here likes to tinker.
Device Model: SM-G900T
CM Version: 12.1-20150704-NIGHTLY-klte
Android Version: 5.1.1
Baseband Versioin: G900TUVU1DOB1

Should you upgrade your Moto G to 4.4.2 or 4.4.4?

Simple answer - NO.
When a new software release is made for an OS, all the developers would have done is test it on a very few devices within the developers and then roll it out to testers. And after analyzing the bugs identified from these testers, the developers sit on fixing it and finally come up with a release. Now would this release be bug-less? Absolutely not! Remember, its only been tested amongst a very few number of people and the rolling out happens to thousands residing in different parts of the world. If you think about it, what these updates are gonna deal with is a varied number of users, different carriers, sim make etc etc.
Take for example, for Indian users, the 4.4.2 update has been rolled out for quite a while. Lots of bugs were identified since then and the forum managers have been collecting data from the subscribers for quite a while now (Almost 4 months). Still the fix has not happened. And now 4.4.4 is out and issues persist.
I hvae been using 4.3, 4.4.2, then CM11, Mokee ROM etc etc, and now Im finally back to stock 4.3, coz thats the most stable version. So if you are someone who is interested in trying out new releases, please go ahead, but if you are someone who needs a stable ROM with no signal drop issues, please stick to 4.3.
totally disagree. I have european version Moto G with stock 4.4.2 and everything is working perfeclty. Try to wipe you Moto or flash any other rom.
seems like pebkac not buggy firmware . otherwise every single guy would be facing same problems and that's not happening .

Just to clarify, did you receive an update package sometime after the primary update?
4.4.3 works fine on my US GSM moto G. But it might be different for others.
Also, add a warning to the OP that if you're already on 4.4.3+, you can't downgrade anymore. Motoboot from 4.4.3+ doesn't seem to like downgrading anymore, unfortunately.
4.2.2 works great, no signal drops or anything. Waiting for eupean 4.4.4. :good:

Question is whether downgrading is possible from 4.4.4 ?
I totally agree to ovitz. Updates are supposed to fix issues with older versions of the software. My moto came with 4.4.2 and i never had issues with signal drops. I am from India. Btw it's always better to reset phone after the update.
I agree with you OP on some extent. I also recently downgraded to 4.3 from 4.4.2 just for the lulz, because I was getting "image is too large" error but surprisingly today the flashing was successful. The battery timing has improved, dialer app is cooler than that of the 4.4.2. I'm finding these changes quite interesting because I didn't stay with 4.3 for too long; my Moto G received the KitKat update the moment I powered it on for the first time.

While I do agree with you for most of what you said, not everyone has bugs or issues with their phones on 4.4.3/4.4.4 upgrade. I myself has had one bug that came with the phone since 4.3 and it's worst now on 4.4.3 and ironically, I've gotten all the bugs on the 4.4.3 that others were getting on 4.4.2. I ended up putting on CM11 because it was getting to me.
P.S. It's impossible to downgrade from 4.4.3/4.4.4. I would love to downgrade back to 4.3. Never got the chance to see how it behaved on my phone because I updated to 4.4.2 the moment I booted for the first time.
Did I mention the "Sign in to WiFi" error on the 4.4.2? That's annoying as hell.

It is possible!, download the 4.4 official ROM and do a fastboot and install all the IMG files.
Thats how I did it,

but you can't downgrade the bootloader, so didn't you get any errors?
Not that guy, Don't touch the motoboot and you should be fine
There's no point of updating your phone unless youare receiving it over OTA. Doing it manually is risky. The only thing that you'll get is new AOSP dialer and few security fixes. There's no reward..no improvement in performance as well as in camera quality. People are reporting bugs all over the globe and they desperatly want to switch back to 4.4.2. Few have them are also facing downgrading issues.
And you want to go through all this for just a minor update? Android L could be a good reason as it is worth updating even after bugs. But a minor update is definitely not.
If some one will ask me which is best ROM for my moto g? I would say Stock 4.4.2. I tried all custom ROMs but no one was as smooth as stock 4.4.2.
Consequences be damn'ed.
Simple answer- yeah, well, that's just like your opinion man.
Indian user. Unlocker my bootloader, Converted to GPE while on 4.4.2. The GpE move was made partly because I had jo desire nor the use if a second sim and mostly because I wanted a clean OS. Period.
Got instant OTA update to 4.4.4 to the day it was pushed.
No issues so far, None in fact and it's been over a week or thereabouts(I admit to the likelihood of me being an isolated case)
Lastly, to each his own.
Android is meant to be taken care of AS WELL tinker every single detail or option if you have the cojones for it. Ciao.

I have just upgrade to 4.4.4 XT1033 (Malaysian), noted the missing 2 empty simcard icone and new rather flat dialer! nothing much has changed and certainly hasn't noticed any issue mentioned herein!
If one were to go by op opinion then they would be using 4.3 for the rest of the devices life ! I wonder what his comment would be once L comes to our device.
I have to disagree the OP as an xt1033 owner since march 2014.
Android 4.4.4 OTA for moto g helps fix various sw issues and increased performance,new baseband to aid the radio issues. Media playback is improved. The device is more of a swiss-tool now.

New to Flashing, Want to install Eclipse [Note 3]

Hello everyone.
Is there a one true guide to installing a ROM on my Note 3? I'm running a T-Mobile N-900T. It seems that after browsing the web, I've seen so many different ways to install a ROM that I'm extremely hesitant to try one on the off-chance that it is no longer supported and may brick my device. This is a non-warrantied phone (bought it on Swappa) so I only get once chance if I end up Hard Bricking it, so my fear level is at the absolute highest.
I wanted to run Eclipse Note 3 TW Rom (found here: http://forum.xda-developers.com/showthread.php?t=2620723) because it's a nice simple ROM that retains S-Pen function and removes all the bloat and stuff. However, I noticed that it says "This is based off of 4.4.2 NC2 for Verizon Wireless." Does this mean it won't work with a T-Mobile Note 3?
This is as far as I got in towards the process before I stopped due to something unexpected:
1) TowelRoot. Rooted it and confirmed with the Root app that it was indeed rooted.
2) Downloaded SuperSU. I installed the binary using the Normal mode since I didn't have CWM or TWRM at the time. It asked me to disable KNOX and it looks like it was fine. I restarted it.
This is where I stopped. After I installed it, it asked me to confirm if I want to confirm allowing Freedom and SetCPU. I did and it continuously started spamming the notification that it was allowed for 20 minutes.
I went into the SuperSU program to see what's wrong and it then told me that the Binary could NOT be found and that I may have to flash my rom back to get it back to normal. It then gave me the error that something was wrong on my phone and that I might have to install something called Samsung Kies to make it better.
I pretty much freaked out at this point and de-installed SuperSU out of fear that I might screw up my phone. Now I'm extremely fearful to do anything without seeing some sort of de facto guide on what to do next.
If it helps, here's the phone information I have. I know that different ROM flashing methods are used for various kernels.
Model: SM-N900T
Android Version: 4.4.2
Baseband: N900TUVUCNB4
Kernel: 3.4.0-660648 | [email protected] #1 | Wed Feb 12 21:31:27 KST 2014
Build Number: KOT49H.N900TUVUCNB4
SE for Android Status: Enforcing | SEPF_SM-900T_4.4.2_0005 | WED FEB 12 21:31:01 2014
Security Software Version: MDF v1.0 Release 2
I have a 128GB Samsung SDXS MicroSD. The phone recognizes 119 GB of it which I know is normal.
Any help or direction would be most appreciated. The world of Flashing has so many roads that my head is spinning and my fear is that I will turn this phone into a $500 brick because I followed the wrong guide.
Thank you.

Thanks.
I do understand that and I have the program, but I can't find any SOLID documentation. I see all these different guides out there and I'm scared that I'm going to pick the wrong one. The ages vary as well, so I don't know if they are still relevant or not.
Not only that, I don't believe that just Odin is enough. There are also prerequisites that are required before I can just up and use Odin. That'st he part that I would hope a decent guide out there would provide me.
A bit early by a few minutes but, Bump for help.
Any information or leads would be terrific.
Thank you.

[Q] Rooting Note III Question

Yes, this has probably been gone over ad nauseum throughout the site. Due to time constraints I cannot dig through the forums as much as I'd like, so I'm simply going to ask.
Phone: Samsung Note III (SM-N900V)
Carrier: Verizon Wireless
OS Version: 4.4.2
Baseband Version: N900VVRUCNC4
Kernal Version: 3.4.0
Build Number: KOT49H.N900VVRUCNC4
Hardware Version: N900V.07
It was purchased November 2013 with OS 4.3. Over the summer I accepted the OTA update to 4.4.2. My phone went to hell. Battery gets chewed through like a woodchipper, phone is horribly laggy, antenna connection is always 1-2 bars under where it was prior to update (and doesn't get reception in areas it did before), changes to the UI are less than desirable, etc.
The phone was never rooted, as this was the first phone I've ever had that worked well enough on stock software that I skipped it.
After giving it a few months on the update and trying changes/tweaks within the updated stock software to fix the issues the update caused, I'm at the end of my patience. Contacting support at both Verizon and Samsung was pointless, with one blaming the other for the problems.
What I'd love is to take the OS back to 4.3 and leave it, but in lieu of that I want to root the hell out of it and put a build on without these issues and a better antenna software. I'd prefer not to void the KNOX, but at this point I'd microwave it if it'd help.
I have no backups or root access from before the update to base a root on. I tried towelroot; install button doesn't work and I understand the maker Geohot works for Google now. I started to play with Odin, however the install seems to have an oddly high amount of other software it wants to install, and even after declining those it doesn't want to install (tried 3.09 and 3.10, I'm using Windows 7 w/latest SP and updates). Also, it drives my AV software crazy, so even turning that off and working with it didn't get me very far.
So, at this point, I'm open to most anything to get this crap off my phone, and my only requirement is that I don't brick it.
Options?
Thanks in advance for any help.

This is the best breakdown of what you need to do. Click here, scroll till you see the blue outline for NC4 OTA.
Be sure to hit "thanks" on @az_biker link for this tutorial!
Unfortunately this won't work, I've already tried. When running the towelroot installer the Install button is not clickable. The other buttons function normally.

No to both, unfortunately.
I've had no issues with towelroot. But for giggles make sure you have install from unknown source checked, and then unlock your developer options and make sure USB debug is enabled, then give it another shot.

I have not, since the leaked NC2 firmware was leaked out. However on my s4 I just used towelroot with the latest NC5 firmware, and it worked flawlessly.

[Q] Downgrading from CM12 nightly to CM10.2?

About a month ago, I decided to take a leap and try the new CM12 nightly on my GS4 (L720).....what a horrible idea that was. Half the themes don't work properly, I couldn't get any form of data access because it kept popping up a message "No APN specified on device" but there's no APN settings as there was with previous (FULL) versions, as well as many other issues. I had another GS4 with a solid version of CM10.2 (I think, may have been 10.1) but the screen shattered on that one and I had to get a new one through insurance claim. I've heard that because of something in updated versions of Android (ie, 5.x over 4.4.4) that won't allow downgrading. Is this true, or can I just flash a stable version of 10.2 after reformatting my phone in recovery? If what I've heard IS true, is there any way I can at least get back to stock 4.4.4 if nothing else? I'm not about to go in blindly despite my lack of patience for this thing and potentially brick my phone o.o

Also, for at least a week before I did, I kept getting a message about the OTA 5.0 update, yet last I knew they hadn't fully perfected/released 5.0 for the Sprint GS4, but had already pushed on AT&T, Verizon, etc. months prior. Is 5.0 not meant to run on the L720? (Not the Tri-band. I got an L720T/Sprint Spark variant out of the box when I upgraded, but they replace it with a standard LTE L720 whenever I get a replacement through insurance...what I get for going to worst buy?)
You can't downgrade the firmware, you can flash any ROM I want.

T-Mobile Updating Baseband/Modem?

It's been a while since I last did this, and I'm afraid I'm quite confused...
I am running a custom ROM (Bliss Beta 6) but remembered that updating my ROM doesn't update my baseband/modem.
Are baseband and modem the same thing?
https://support.t-mobile.com/docs/DOC-10398
Using this site here I see that my current baseband (G900TUVU1CNK2) is super outdated. It tells me that G900T3UVU1FOG6 or G900TUVS1FOL1 are the latest, but I don't get why there are two. Which one should I install?
All that being said, can I install using TWRP and a zip, or do I need to ODIN it?
Any help would be appreciated, as I said I've done this before but can't find any updated tutorials that explain the questions I'm asking (I've tried searching google and XDA, if I missed something obvious I would appreciate a link!).
cheers
More research has helped me answer my own question! Sharing what I've found in case anyone else comes across this thread:
Baseband and Modem are effectively the same thing in this context.
G900T3UVU1FOG6 was released in August 2015 and has the fix for stage-fright.
G900TUVS1FOJ4 was released in November 2015
G900TUVS1FOL1 is pretty much brand new (released in December 2015) so there's not a lot on it. This is the one I'm going to try installing.
Followed the instructions from this thread http://forum.xda-developers.com/tmo.../compilation-s5-g900t-stock-firmware-t3042400 to figure it out.

i've been wondering this myself, so did you update your baseband & is there any change in battery or signal quality? (or i guess stagefright detector?)
also wondering if downgrading is no problem or if it affects anything like that (which stock samsung or other device kernels/ROMs do, sometimes blocking root etc)
Hey, so I actually updated to G900TUVS1FOL1 using ODIN. It nuked everything and installed regular TouchWiz which I wasn't a fan of, but I have no problem installing my own ROM later.
If you're doing the T-Mobile one, then there is no issue with rooting, installing kernels, custom ROMs, etc. I don't really know about "downgrading" the baseband or modem, but I don't think you would need to in this case.
Note that if you have Verizon or At&T you probably want to be SUPER careful, because they lock down everything.

yes, I installed G900TUVS1FOL1 with Odin, had root and TWRP installed just fine (couldn't get xposed to work because it was not a deoxdex rom of course). I just installed BlissPop ROM last night which is based on CM13. So yes, it didn't lock me down or anything.
