What radio are my fellow T-Mobile user using?
[Nexus 5 Android Development] benzso63:
Originally I was using

KTU84P (4.4.4)

M8974A-2.0.50.1.16

Then I switched it to

KRT16M (4.4)

M8974A-1.0.25.0.17

Unfortunately I thought it was better but actually the same. I don't get better signal in my kitchen area. Either one bar or none.

Anyone capture an OTA in Europe / UK it might have different radio maybe ?
[Nexus 5 Android Development] :
The last few posts have been about what radio to use, so I'll provide an answer to all prior posts (and, hopefully, all similar queries in the future).

[MENTION=4995561]phattboy[/MENTION] [MENTION=4537737]faultytowersdude[/MENTION] [MENTION=2749621]mazsuper[/MENTION] The beauty of a radio is that you can flash them all and try them without the need for a clean flash.

Long story short, you can flash them all on separate days and see what works best for your phone. Different radios function best for different phones, so you have to try them all.

OP updated with LPV79 radio

LPV79 (L Preview)

M8974A-2.0.50.2.08

AAAAANAZQ20500018

QUALCOMM Incorporated May 7 2014

interesting it has an older build date on it.

updated name... from lpv79-preview-ac1d8a8e to LPV79. I'll assume the next build will be LPV80 and we'll be able to tell them apart that way... rather than use the ugly "lpv79-preview-ac1d8a8e-type" names. If not.. I will revert back to the ugly name ;)
[Nexus 5 Android Development] Rip95:
It has the same build date with 4.4.3 radio, but it has less size and works slightly better (maybe it's just placebo).
[Nexus 5 Android Development] :
I'd bet they've been working on it for a while. They want the major release to be pretty solid.
[Nexus 5 Android Development] RED ZMAN:
Thanks for the great thread, I've updated my radio several times from this one.

I keep seeing folks talking about updating the bootloader, I've never done this that I can think of. I haven't been able to find a thread about it for the Nexus 5 either, can anyone share some helpful information about updating it? A thread, suggestions, etc.

[Nexus 5 Android Development] mybook4:
Interesting, but I still doubt changing one resistor will change the D820 into the D821 (or the other way around).

I'd be interested to see what the result of changing this magic resistor would be. Unfortunately we only have a D821 service manual and not the D820 as well. With the amount of RF info in those documents, we could know almost certainly whether or not bands could be added/changed/whatever. I'm in the US and have no need for a D821, so I'm definitely not trying this.

[Nexus 5 Android Development] h9290:
Me too!! i tried flashing the D821 radio but nothing changed. As mentioned earlier, so far the latest radios are the same.

I was considering getting a D821 but couldn't switch into the UK play market.

I know eventually we will get the hybrid modems around just like the Nexus 4, but should i wait or trade with someone who will make better use of the 820?

I don't see a logical way to recover your new imei.. But if you have the new imei written on the phone or something , you could attempt via adb I guess.. A little scary scenario..hope you find a way out
[Nexus 5 Android Development] bamboosensei:
Thanks masterg0g0, I appreciate the comment. I'll see what I can do. I guess for anyone else who might check this thread, I'd recommend backing up your EFS folder as soon as you get the phone and to make sure you either label it so you know specifically what phone it belongs to and not to restore it when using nandroid unless you need to just to, prevent any inconvenience. My incompetence in this matter was clearly my fault so hopefully no-one else has to experience the same thing too.

Updated OP with new modem...

D820 KRT01B
[Nexus 5 Android Development] wideasleep1:
Thanks for keeping/updating the list!

This update appears to be an slightly older modem by revision, but newer by date...odd.

I'm getting poor LTE performance on my N5 using .17 modem, yet swapping the SIM back into my N4 running morrislee's hybrid .33/.54 modem throws me right back into low/mid 20's mbps. Would appreciate anyone that flashes radios report back their LTE perfromance, especially on TMOUSA. Cheers!
[Nexus 5 Android Development] quadomatic:
Flashing now. I will post speed test results when I have them.
[Nexus 5 Android Development] wideasleep1:
Many thanks...were you getting the fast spike then major slowdown behavior? Cheers!
[Nexus 5 Android Development] quadomatic:
Speeds seem to be about the same with this modem (KRT01B: speeds range from 2 to 7 Mb down; Manhattan, NY).

I was never getting a fast spike with slowdown.
[Nexus 5 Android Development] JoshuaFCB:
edit never mind
[Nexus 5 Android Development] wideasleep1:
Okiedoke...I'm getting low 20's for about 5-8 seconds then slowdown to anywhere from 3-12mbps and it's erratic. Downloading apks from Play is annoying when a simple 8 meg file shoots to 80% instantly then takes minutes to complete. Same SIM in N4 is fine. Hopefully not a hardware bug in my N5.
[Nexus 5 Android Development] quadomatic:
I wonder if it's an issue of your IMEI not being on file with T-Mobile?

Sent from my Nexus 5
[Nexus 5 Android Development] quadomatic:
It's likely that LTE speeds are just worse where I live (UES/East Harlem). I've seen speeds 20-40 Mbps on AT&T around the city. I might try taking the T-Mobile sim card around to different parts of the city to do speed tests.

If it is an issue specific to my phone, hopefully a new modem flash will remedy the situation.
[Nexus 5 Android Development] RussianBear:
Try hspa+. I'm getting much better speed with it than lte. N4 h+ wasn't nearly as good.
[Nexus 5 Android Development] zephiK:
Try it yourself, just because its better for him/her doesn't mean its better for you because you two live in different parts of the world.

[Nexus 5 Android Development] Tylog:
Best way is, test it self. So many providers, we all are on other places, nobody can tell you if the modem is better or not for you. It's really no big deal to flash it, test it, stay with it or flash back :)

this is weird, i flashed the preview radio and had no data connectivity until i made a phone call. i flashed back to ktu48p and still have the same problem...
[Nexus 5 Android Development] EvanA:
I wouldn't use that one because it does not have spark or band 26 (low frequency LTE) support. You should use .16. .13 has issues but .16 fixed them and now it performs on par with .17 and has spark and band 26 support.

I've come to the conclusion that there isn't ONE best kernel, rom, modem across the board... regardless if carrier/location is shared.

I'm not sure if it's variations in the hardware or what... but I think everyone should try out their own combos to find what is best for them.

L modem has done well for me on both 4.4.4 and L... on both TMO and SPR.

[Nexus 5 Android Development] MkVsTheWorld:
The 4.4.2, 4.4.3, and 4.4.4 modem radios were poor performers in the DC area on AT&T. I'm testing the L preview to see if it's an improvement.
[Nexus 5 Android Development] osi13:
The new L radio was not very good for me. I took the time to flash 4 or 5 different radios, switched to text signal style on CM and narrowed it down to the KRT16M radio. I was going in and out of service with the L radio in my house. Everyone should take the time to find the best radio for their device because it appears that the latest version is not always the best version.
[Nexus 5 Android Development] Dougshell:

[Nexus 5 Android Development] dunjamon:
I tried the L radio, but my signal kept dropping and then reconnecting and dropping again. I barely get a 4g signal using 4.4.4 on three uk., was hoping the L radio would boost it a bit.

Has anyone used the L radio on 4.4.4? Or does it not work?
[Nexus 5 Android Development] Koopa777:
L uses a different radio algorithm for searching and connecting to towers. I would assume that thinking is also built into the radio. So I personally would not recommend using L radio on KK.
[Nexus 5 Android Development] EvanA:
How can you say that? Do you have access to the source code? Nobody knows what the radio updates change, we can only observe how they function. L radio is perfectly fine on kitkat, I've been using it since the L preview was released. Also, the release/radio combination does matter. You'll get the same results from an individual radio no matter what release it is paired with.
[Nexus 5 Android Development] Koopa777:
It was confirmed by an engineer at Google. The exact words were something along the lines of "improvements to the network connectivity algorithm." I'd search for the source, but it's 11:24, and I honestly don't care at the moment. =P All I remember is that it was posted on either Droid-Life or Android Police.

Also, I noticed significant improvement to radio connectivity, especially the bull crap issue with "sticky" 3G CDMA, and not switching to LTE automatically. I'll also had no signal 90% of the time off on the new radios, which is why I switched back.
[Nexus 5 Android Development] MkVsTheWorld:
L Preview didn't help me. I'm experimenting with 15/17/23 and am finding better throughput on those radios with AT&T on HSPA. I'm just narrowing down the winner in my area.

Side note: Google is aware of signal issues since 4.4.2.
