I was previously on M8974A-1.0.25.0.23 (4.4.1) as well and after flashing the lastest, M8974A-2.0.50.1.13, my phone falls back to H+ more often and hangs on to it for much longer. Often times, I need to toggle LTE off and then on in order to switch back.

For whatever reason, I've literally never gotten 4G, even before I used modems. I live in the middle of Silicon Valley, so 4G seems like a given. Am I getting 4G and my ROM just doesn't show it?

More than likely its your APN settings. I had that same problem and the settings I got online fixed it.

I did this and it only seemed to get worse.

I get H+ and H. I've heard that H+ is very slightly worse than 4G, so I wouldn't be too distraught if I couldn't find a solution, but obviously I'd like to try.
[Nexus 5 Android Development] MaxRabbit:
There's a huge difference between H+ and LTE.
[Nexus 5 Android Development] ritchea:
Don't know if it does anything but try adding hipri to your APN list/type . It stands for high priority. I have it on my gophone APN but think I added it.

[MENTION=2684188]autoprime[/MENTION] if you are saying that D820 radio .img is the same as the D821 then how come your KTU84M image is 64mb but my D821 radio KTU84M image is only 44.3mb??
[Nexus 5 Android Development] autoprime:
because 44.3 is the stock size of the image file but the modem partition where that file goes is 64MB+...

so.. I take the original 44.xMB file and inflate it with 00s to fill out the exact partition size.. down to the very byte.

This gives the modem write a good write every time.. whether you erased the partition first or not.

so despite the different total file sizes the actual data inside of the files is exactly the same.. one just has more 00s at the end. ;)

[Nexus 5 Android Development] Blac Caesar:
All the radios should work on 4.4.2, except for maybe the latest, KTU84M, as that one specifically came with 4.4.3. I've tested most of the others while on 4.4.2 myself, they worked for me.. you can flash em n see what works best for you though. I'm on Paranoid Android's RC2 4.4.3, so I'm using KTU84M

EDIT: D820 is US version, D821 is international

You'll have to ask in their development thread if they support Hammerhead.. TWRP does for sure, it's the only recovery I've ever used

In TWRP, just click "Backup" and select what you want to backup, then slide the indicator to the right to begin your NANdroid. I can't speak for other recoveries, bc I only use TWRP

If you're rooted, your warranty is voided already.. so that shouldn't be a worry anymore lol ?

Radio signal constantly drops

Hey Guys,

So I was on slimkat and I had a problem where every 5 mins my signal will drop to zero. nothing at all, messages wont send etc. It only last about 30 seconds but is CRAZY annoying so I flashed all of these modems/radios, nothing changed, same problem. I then flashed paranoid and tried all radios, same issue. What is my next step to fixing this? It was never a problem before slimkat but is still a problem when I have paranoid, usually these problems go away when i wipe everything and start fresh with a new rom but it didnt this time.. HELP!! please and thanks! Im on Rogers in Canada if it's relevent
[Nexus 5 Android Development] hooliganx:
[MENTION=4232148]MikeLibbey[/MENTION]

only thing I can say is.. not a Rom problem.

I use Slim since S1, S2, S3, Note 2, Nexus 4 and now, Nexus 5. and never had problems.

use Paranoid for a quick moments too, and no problem. (Im from Brazil) ;)

maybe a problem with modem. try a clean install and use a first modem you use and work. search in a modem thread a better modem for your location. ;)

good luck :thumbup:

N5*SlimKat.5.0.(4.4.2)*El-X.045

*ART*TWRP.2.7.0*0.13
[Nexus 5 Android Development] MikeLibbey:
Thanks for the reply! I did do a clean install and used the first modem it came with, for both of them, i was hoping to be pointed towards another modem thread as i have very little time right now but i guess i'll search when i have some more time, thanks. Again, i'm not blaming the roms cause i tried 2 and still have the problem, just seems weird.
[Nexus 5 Android Development] jwhyte:
You said you tried all the modems. You may or may not notice a difference depending on coverage. You can always double check your APN settings and even toggle to 2g, 2g3g, or LTE to get a stronger signal. I'm on T-Mobile us and I always toggle to 2g only at home and work because LTE and 3g are very weak by me.
[Nexus 5 Android Development] MikeLibbey:
Hey thanks for the reply. It's not that I have a bad signal, I have a fine signal, WHEN IT WORKS. It literally cuts out every 5 minutes to zero bars for no reason and comes back in about 30 seconds. Every 5 minutes flawlessly. Any other ideas?? lol
[Nexus 5 Android Development] jwhyte:
No. You said you had no issue before... There shouldn't be anything in the ROM itself that would cause that just APN settings. Modem is entirely separate from ROM.
[Nexus 5 Android Development] MikeLibbey:
Yes I know it's not the Rom... That's my question.. What is it?

MASSIVE difference here, before had -93dbm and 8 asu. Now getting -83dbm 15asu. Much more stable connection here on 3 UK. I've got a feeling this radio update was mainly for GSM performance as before I had 4 bars signal whereas I now have 5. My Sensation also had 5 -85dbm 12asu so it was always puzzling why my N5 had a weaker antenna than a Sensation. Glad to see Google finally fix it :)
[Nexus 5 Android Development] kronflux:
I'm not on sprint, I'm on Rogers in Canada. But I had -terrible- performance on the 4.4.3, whereas the 4.4.2 modem was perfectly fine.

Hopefully that means you'll get better performance too!

So many things wrong with this post.

The latest radio may have a bad signal for you, that doesn't mean it "sucks" - it means it sucks for you. Works the best for me. You also need to look at your coverage in your area.

Not a fair statement at all.
[Nexus 5 Android Development] benzso63:
I will have to agree with 1ManWolfePack.

I don't see any improvement on my end either but that's how it is. Probably the coverage in my area is bad. But you can't just say it sucks.

Others might benefit from it and may be just few of us don't. Relax bro, not everything is perfect in life.
[Nexus 5 Android Development] sirovai:
Compared to the others devices the radio (and also the gps) haven't good performance. This is a statement and you can see this across the Web and the Google product forum. I personally RMA two devices (one for GPS didn't work and another with strange behavior with signal that I didn't solve with the new one...). Maybe "sucks" is a bit exaggerated but the problems are there. Beside this the N5 is an awesome device.

[Nexus 5 Android Development] Natakranta:
Take it easy ;)

Just remember that custom ROMs don't provide bootloader or radio images in their custom recovery flashable zips. When the new iteration of android is released you need to take care of it on your own. First read if the radio and bootloader were updated to newer version, both, one or none of them can be. For example going from 4.4.1 to 4.4.2 radio was not updated. But then it was on 4.4.3 and again on 4.4.4.

You can either download the factory image from Google, extract it and fastboot flash the radio.img and / or the bootloader.img or for any version of radio you can download custom recovery flashable zip from link provided in OP of this thread.
