My modem was always stock. Just reflashed it because I didn't know what else to do.

edit: Is it safe to completely wipe the radio before flashing it again? Or will I bork my phone that way?

edit: I got it. Instead of flashing the radio.img through fastboot, I flashed the zip through TWRP and now the update is working. I think it had something to do with the partition itself, I had some issues last night with messed up partitions. After flashing the radio.zip in TWRP it updated the partition details and I think that's what allowed it to work.

there is a new modem for d821?
[Nexus 5 Android Development] Akarim47:
Thanks. found it:good:
[Nexus 5 Android Development] 850T5m:
Quick question, the OP says "d820/821 have matching md5, so they're the same modem"

Can we flash either one? Why does everyone keep asking for specifically the 821 or 820 modem if that's the case?
[Nexus 5 Android Development] 75markus:
yeah, forget my previous post, there are no different modems for us & europe, they are the same file.

i just flashed the .23 radio img posted before, it also works fine in europe ;)
[Nexus 5 Android Development] WoodburyMan:
Used zip from first page link "D820 KRT16M

M8974A-1.0.25.0.17

AAAAANAZQ1025019" and inserted quoted modem .img file into the zip. Flashed in TWRP, and it works on CM11. Currently tested with LTE and HSPA+ on AT&T just fine. Baseband now reads M8974A-1.0.25.0.23

Can the older modems get flashed with the newest 4.4.1 update. I like the new software but the LTE connectivity went down the toilet.

Are you telling that new modem .23 came with 4.4.1 update works worst than older modem versions?
[Nexus 5 Android Development] chugger93:
Are we supposed to flash 820 and 821 modems? Or just one of them? I'm still on stock modem
[Nexus 5 Android Development] :
Hi,

Only one of them or one will be replaced by another if you flash both, depending where you bought it (your location):

When I first bought this phone I connected to LTE all around town. Since this update I rarely connect to LTE now.
[Nexus 5 Android Development] Dungeon47:
Is the bootloader hardware agnostic in this case? Meaning 820 vs 821, not device vs device.
[Nexus 5 Android Development] apfelstyle:
Is there a D821 flashable .23 modem zip available?

Gesendet von meinem Nexus 5 mit Tapatalk
[Nexus 5 Android Development] pchtc:
if you have issues on .23

try .17 or .15

several people reported .15 locking onto lte better that .17
[Nexus 5 Android Development] tybo31316:
I went back to .17 everything is fine now thanks
[Nexus 5 Android Development] WoodburyMan:
X2 Wondering as well before I flash. Likewise any side effects? (Does it matter if bootloader is locked or unlocked?)
[Nexus 5 Android Development] pchtc:
if your bootloader is unlocked and you flash a new bootloader

it will still be unlocked

the radio is secific to the model 820/821 though you can still flash it

the bootloader i dont believe is model specific, it should be fine on 820/821

mine is 820 and has flashed
[Nexus 5 Android Development] Dungeon47:
Confirmed. Bootloader and modem running fine on my 820 with a pre 4.4.1 Omni build. So it appears you can pre-emptively flash bootloader/radio if your ROM isn't up there yet. YMMV.
[Nexus 5 Android Development] 75markus:
no

no, check the OP, there are no specific 820/821 versions, they are the same file, same MD5

new bootloader and modem also confirmed working fine on my 821, running cataclysm 4.4 :)

What's newer..the .17 or .15 build

Not counting the newest releases.
[Nexus 5 Android Development] melbourne408:
.17 is newer than .15 , the latest 4.1 radio is really limiting my download speeds on AT&T
[Nexus 5 Android Development] autoprime:
both modems are the same. flashing a D820 modem instead of D821 will add nothing. The only difference you will will is when flashing different D820 modems since we have different builds of the D820 modem.

the .15 build was built more recently. I include the build date under every modem. So while .17 is a higher version... the .15 build was built after .17
[Nexus 5 Android Development] ChazzMatt:
I'll be going to Brazil again next year. So, flashing the D821 modem will not give me Brazil LTE, eh?

[Nexus 5 Android Development] DroidIt!:
Just to confirm, I am on latest SlimKat with Faux and TWRP. Went to recovery, did a nand and flashed the new bootloader. Rebooted to bootloader to make sure it took and all was good. Rebooted to recovery and flashed the latest modem rebooted to rom and update also took. My data speed I'd have to say is at least 30% faster. After flashing the modems, initially recovery was a little slugish but ignored it and rebooted to the rom anyways. At initial boot, got "Android is upgrading" message and got stuck at lockscreen for a bit. Just let my phone sit for about 5 minutes, I didn't touch anything, turned it back on and all is running great now. :good:
[Nexus 5 Android Development] tybo31316:
The latest was causing problems for me also. It decreased my Sprint LTE reception significantly. I went back down to .17
[Nexus 5 Android Development] adriangb:
I really don't know about the Brazil thing, what I was saying is that based on the bands in the US radio, my device would work in Argentina, hence I don't even need to flash another modem...

[Nexus 5 Android Development] peikojose:
Will this work with my LG D821 (International versión )? Please...!
[Nexus 5 Android Development] jcsww:
The radio hardware in each device is exactly the same regardless of the version. The radio software just limits the bands your particular device look at for service. Either radio will work on either model. Hopefully at some point, someone will be able to merge the two radio images in to one.
[Nexus 5 Android Development] aavvaallooss:
Yes
[Nexus 5 Android Development] jd1639:
[MENTION=3116388]jcsww[/MENTION]. What? If the hardware is the same and the software is the same, then why does one get lte outside the US and the other doesn't. And if the software is different why do they both have the same md5?
[Nexus 5 Android Development] :
Wow so far new modem doing wonders for me in a house I usually get no service in lol
[Nexus 5 Android Development] jcsww:
My guess would be is they have two different software versions of the radio on the same piece of hardware to cut down on how much battery it uses on scanning what it doesn't need to be scanning. In certain regions, some of the bands that North America uses are not used at all so they are not needed. The only reason I would like to see the two merged is because I travel a lot. Between Rogers Canada, T-Mobile USA, and T-Mobile UK or Vodafone UK, it's less hassle for me to have the radios all in one. Also, Rogers Canada Uses 4 and 7 for LTE so that would give me better coverage in Canada as well.

Thanks. Was hoping my eyes weren't that bad lol. I just found them in the general section.
[Nexus 5 Android Development] lexusmike:
I get much better LTE on the .15 modem but it says "searching for service". I'm on sprint. Pages will load and data works great but when trying to update profile in the mobile network settings it gives an error saying "you cannot update profile while the device has no service".

Does anyone know how to fix this? I'm loving these radios, other than this one issue. I'm on a 4.4.1 rom if that matters.

It looks as if cell standby is eating through the battery too. Even though connected to LTE it seems to still be looking to connect to the sprint network.
[Nexus 5 Android Development] cjwaggsrx8:
I'm wondering the same.. Exactly the same issue. Great LTE with .15 but searching for service. Can't make calls but data works great.. Real weird. The newest .23 connects to sprint no problem but no LTE . hmm.
[Nexus 5 Android Development] lexusmike:
After doing some research this seems to be a sprint network issue. If your in a region with Samsung or Motorola towers then LTE will be spotty or won't connect because of upgrades in process.

I also found forcing LTE only on the .23 radios will yeild the same results as the .15 radio in LTE/CDMA auto mode, being it will connect to LTE but will lose the ability to send or receive calls and texts.
[Nexus 5 Android Development] cjwaggsrx8:
Makes sense. That's what they said when I called them bastards. Glad you can confirm. I get great LTE at work so I know the radio can connect. Hopefully they get it together soon.. This is my this LTE device that I can't actually use the LTE service. Lol
[Nexus 5 Android Development] lexusmike:
Yeah that's Sprint for ya. There's an app called "Network" that allows easy switching between network modes. Seems to be the best fix so far. I think its only some towers with the issue because I don't remember having this problem earlier today when I was in a different area. Might have not noticed though.

[Nexus 5 Android Development] lexusmike:
So I'm in a different area and am getting a solid LTE connection on the .23 radios. Same with the .15 radios, and its not searching for service anymore while on LTE. It says sprint as it should, so the sprint LTE issue is tower specific. Hopefully doesn't last much longer.

It's simply the radio (and bootloader) from 4.4.1. It's .23 now but that one isn't so good others have come to find.

I'm testing .15 now (.17 was good IMO) and it seems just as good.

Sitting on the desk was doing -88-91dBm vs -77-81dBms. So yeah, pretty big difference.

-70s is just great though and -89 is where it will drop down to 3 bars and it goes down lower from there. -117 is basically 0 bars but still connected :p

[Nexus 5 Android Development] autoprime:
boot into fastboot. fastboot flash all the stock images.. including system... but dont flash stock recovery.. instead flash twrp. after fastboot flashing.. boot into twrp... and flash your efs backup zip created from my efs backup zip in the OP. This backup had to have been made prior to your phone getting messed up.

after flashing your backed up efs in twrp.. hit the wipe button > advanced wipe... and wipe data, cache, dalvik.

reboot phone. should work. if not.. possibly a hardware issue... or possible i missed a step but i think i covered the basics.

this is a modem thread.. roms and bootloaders are for another place. the modem is safe to flash.. lots have flashed the modem if you've read thru the last few pages.

but i will not be posting a patched modem in my thread.. i am waiting until images straight from LG/Google are released.
[Nexus 5 Android Development] autoprime:
what happened the same way as everyone else? breaking your efs? did you restore a different nexus 5's efs backup onto this phone? or some other way? the more detailed you can be the better. im having a hard time understanding your exact situation.

im not sure if you can fastboot efs.. but i dont think so. but im not 100% sure. its two different partitions.. so youd have to fastboot flash modemst1 and modemst2.

you could try writing these 2 comands via adb shell while in twrp before flashing the efs zip:

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/modemst1

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/modemst2

D820 is sold in north america

D821 is sold everywhere else.

The main difference is LTE/WCDMA bands and no CDMA on D821

What I wonder is if you flash the D821 radio on a D820 phone if it would work with the different LTE bands because that would rock for travel.
