[Q] G3 Modem/Radio [AOSP | MULTIROM]

A few questions i just wanted to clear up:
I have the d855, The latest flashable version i can find of the modem is 20F, does 20H modem exist? or can i extract it from primary and make a flashable zip for secondary?
Are modem and radio the same thing? (i.e. affect all wireless comms such as bluetooth, wifi & network?)
for Multirom are the radios/modems shared between the roms (inherited from primary) or are the modems seperate (im talking about mixing stock based roms with the likes of cm12 as secondary/ third)
do aosp roms have the latest modem? using cm12 nightlies atm.
Main reason being having network issues, 4g doesnt seem as fast, and i have horrible bluetooth stutter (that i dont see in my nexus 9 or 5 with cm12)
p.s. i will try add as many answers to the OP as possible when i get/find some
___________________________________________________________________
Off topic -> ive been testing my secondary roms in 1600x900 @ 341dpi (almost looks like normal) on cm12. performance is great! quick browser benchmarks show 31% increase in graphics/javascript and general performance (no animation lag at all). Is there a way to limit fps for the entire device. like KK introduced 60fps limit. how about this lower resolution with better performance. but at 40fps cap to save more battery?
let me know if you find the resolution stuff interesting once i get these roms working well ill release some tests on my blog (on sig)​

Hi, I don't have the same G3, but I can answer some questions.
Yes, modem and radio are the same thing. I think I found out that WIFI is not controlled by the modem on the G3; don't know about bluetooth.
Custom ROMs do not usually contain a modem at all, they leave that up to you and they (try to) use whatever modem you have in your system. You can use different modems with different ROMs by flashing them separately from the ROM. I don't know if you can automate that with MultiROM.
Assume that everything I didn't answer, I don't know. ? Good luck!

Thanks you! everything you've said makes sense my guess is if bluetooth and wifi are not controlled by the modem then updating the modem likely wont fix the bluetooth issue -> however i notices 3-4 bluetooth commits on today cm12 nightly. ill check out how that comes along!

What modem are you currently using?
I was about to make a thread until i saw yours. My data does not work at all after flashing a custom rom,
so i guess slower data would be better than none at all for now.

Well im running primary rom as chupachups (20H base) with 20E Chupa Kexec kernel. and as explained above i guess my secondary rom inherits whatever radio is primary or existing before the flash. Ive flashed 20F a while a go no idea what im running at the moment (will check after the weekend, im out for a heavy weekend) ill boot into primary and check my modem.
just fyi my second rom is cm12 (latest nightly) Bluetooth audio issues are greatly lessened! instead of audio jumps now i get large blocks of stopping so 2-3 seconds audio halts (may be due to stream catching up) and then like 20ish mins of continueous playback id say thats a huge improvement! will try with offline/cached music too

Wifi slow on CM13 based ROMS - HELP!

Hello, I have an issue with Wifi, it's connecting just fine but it's slow, I have tried with 3 different CM13 based ROM but no luck. My Wifi is fine because the speed is good in other android phones. Is there a fix? What can I do? Thanks in advance!

Thanks for your suggestion. I'm flashing the correct way. I flashed RR too and I'm using the latest TWRP to do it. I haven't messed with the bootloader or modem. I don't wanna mess up my cellphone. I only rooted and then installed TWRP and then the ROM.

did you have everything updated like kernel, bootloader or modem?

okay ,do you have any previous backup of modem and efs partition?
its okay if you are a noob,i am not that good myself. the beauty of xda is that you read alot about your problem which will help you narrow down things.
read about how to see your current modem,bootloader version and what are the latest ones,and how to update them.
its right here on xda forums

Nougat .. kernels and datafixes anyone?

I have finally been able to flash a few Nougat ROMS on my N910V. I have NOT been able to flash any trltevzw ROMS but instead a few trltemo and trltexx ROMS. However when I flashed them and set them up I can get wifi but NO data. I was curious if ANYONE has any kernels and or data fixes for Nougat ROMS and if so maybe a link to share? I odin'd the corresponding TWRP to flash these ROMS, so would I need a kernel and or data fix for thetrltexx ROM or trltemo ROM .. OR would a kernel and or datafix for the actual trltevzw phone I have. Sorry if this doesn't make sense typing fast as im at work.
FORGOT the S8+ will be available in 12 hours and im most likely getting one as im sure a lot of other XDA folks will ... and then the Note 4 will drop lower on the list of active phones and ROMS.

No sim with lineage based roms

Hi, i need some advice about this problem, bcz i searched that a lot but i cdnt find anu solution. Any Lineage based roms, like Viperos, Strelka, Ressurection Remix, Aokp rom etc (Any 7.x.x too i guess) doesnt work well on my n7100. Im flashing them and they are booting fine too, But when the screen came on, they says no sim, when i checked about device i dont see any info about modem. But imei is not erasing. Boot loader mj5, modem nd3 (i just changed it mj7 modem but still same) . When i flash stock rom or Hyper rom or any 4.x.x based rom works fine. I cdnt find any solution bcz i tried everything. Anyone can give me an idea about this ? bcz i stuck with 4.4.x roms. Thanks..

Is the phone running the latest by bootloader and modem? Some custom ROMs require a phone that is running the latest version of both.

Yes , found latest ones in here and flashed some time ago.

Did you update the bootloader and modem by flashing the latest stock rom or just the bootloader and modem? Not sure if this would make a difference.

I tried both way. Stock rom and 4.4.x based custom roms works fine. They were working fine with older modem and bootloader too. I tried to flash lineage based custom roms on working stock rom and custom 4.4.x too, w/o wipe. They did same thing, everything works fine just no sim silly right ?

Very strange that the sim is not detected. I don't have a note 2 to try out Lineage.
Did you post your question in the the ROM's thread in the Development Forum? Perhaps someone there could offer some more advice.

Yep its strange, i guess the real problem is those roms doesnt see what modem i have in device, bcz they are not showing that in about device. Thanks anyway, at least you tried to give some ideas
I didnt post my question in the rom's thread, let me try it.

Actually I'm stuck with stock caused by wifi problem when i used custom rom. It can't connect to any wifi networks. Maybe someday will try to flashing again
