T-mobile friendly radio/Rom

Ok, so I'm on T-mobile and I'm currently running the ParaniodAndroid 3.15 with stock PA kernel and Baseband .33. I'm planning on upgrading the ROM and Kernel to Trinity 24, but I'm wondering if I'm missing out on something. I live in Oklahoma and I'm not sure if T-mobile even has LTE setup here yet, but should I switch basebands and ROMs?
What is the best ROM/kernel/baseband combo for T-mobile users. ( I know this is probably a loaded question) I've been searching around and have read the PA doesn't support baseband .33, but my phone has been working fine. Is this true?
Thanks for any help.

I use Carbon with Matrix. Love this combo. Also, Oklahoma does not have LTE yet.

AOKP ROM + .33 radio/baseband + hippo mod = Tmo LTE sweetness
Kernel choice doesn't matter when it comes to LTE at this point.
Never any issues from day one of Washington, DC LTE launch with above combo. Matter of fact, had mine setup in preperation for LTE rollout.
FYI... You can also run 4.2.1 stock to retain LTE functionality.

There's a fix to retain LTE while on 4.2.2 and using a older radio. it also fixes the no in call audio.
Just follow this guide. I did it yesterday and it works. And yes I'm running the latest PA rom with a .33 radio.

Domestic Unlock Question

Hello Everyone,
I currently have a SPH-L720 that I performed the international sim-unlock on and currently use it in the UK. I plan to use it when I return to the states on Verizon, but am curious if I need to perform the Domestic Sim-unlock and change the LTE bands under the hidden dialer menu or should it work automatically since the phone is currently carrier unlocked and then only need to change the LTE bands? Thanks!

It doesn't support the Verizon LTE bands to begin with. Pretty sure you will never have 4G, if I'm wrong kindly point me to the info.

Ah ok I was under the assumption that I was able to modify my LTE bands as I saw on an S5 tutorial.

Would you mind linking that tutorial? As far as I know you can only change them to bands that are already supported by the device.

No band info avaible on Nougat for GT-i9505

Hi,
I switch yesterday to Nougat from the last CM13. I try many Nougat build, and i get the same problem on all, i can't get the LTE band information.
In CM13 i used tool like "LTE Discovery" to grab it, but in any nougat build i was unable, app tell me some impossible info like Band 1 (2100mhz, this band is not in used for LTE in my country) or stay on unknow band.
I try many tool like LTE Discovery and the result was the same.
Someone know why ?

Did you upgrade your modem to the latest version before switching Android versions? If your version is too old, issues like this can result. Also, when you flashed the Android 7.x ROM, did you start from scratch, i.e. wiped system, data, and internal storage, before flashing? This is pretty much required when changing from one Android version to another.

Off course, i did all of this, i also tested the last 5 modem releases with the same result.

So what happens when you use a different ROM, such as the JDC Team's AOSP?

I have test LineageOS official, unnofficial and the optimized lineage by JDC, all based on lineage. I have download the JDC AOSP but not tested yet.

Insted of the 4G logo normaly this is the band number, sometime i'm on band 1, an impossible thing because this band isn't in use in my country ^^
Also i can say i have no problem to make a phone call or send sms.
I have try to roll back to CM13 and all was working normaly.

The real test is to see if you can get onto the Internet since some carriers route calls through the 3G network. However, have you checked your APN? This sounds like a configuration issue.

Yes i have check my APN and i'm sure it's ok.
I'm sure to be in 4G for data (see the screenshot) and for call i'm also sure to be in 2G or 3G because i don't have VoLTE for the moment (but it's another problem ^^)

You're getting high speed data, which means the LTE radio is working correctly. I believe your issue is related to the hardware drivers being used in the kernel. The problem isn't with Android itself or LTE Discovery, as I installed LTE Discovery just now on my Nexus 6 which runs Android 7.x. It's still being supported and thus includes up to date drivers, and my LTE radio reported the band number. You can try a different kernel and see if that resolves your issue, but you may simply have to live without the band data.

Thanks for your answers, maybe i can report the bug somewhere ?

LineageOS I believe has a Gerrit for bug reports.
