Dropped Calls, Flash-able Modems? - OnePlus 5T Questions & Answers

I am experiencing major issues with dropped calls on 8.1 roms. They have me flash the latest 5.1.5 firmware and this seems to be the issue. Is there a modem in this firmware? Do we have various modems that we can flash to see if we have better experiences?
It seemed to work great on the 9.0 roms and stock roms. I am trying to run No Gapps and using Micro G for spoofing. Could that be causing any issues?

[Q] Paranoid Android 4.5 beta 3 unfixable lingering calling bug

Hello everyone,
I'm posting on here because I can't find any solution to my dilemma which I am sure that other people in the AOSPA legacy community have also experienced. I have been using Paranoid Android on my T989 since the 4.4.3 update and I have regularly updated my roms since then. Somehow ever since I updated my phone to 4.5 beta 3, something prevents me from being able to hear or be heard during regular phone calls around an hour after I restart my phone.
I have tried everything to try to make my phone back to normal, I have updated my versions of AOSPA, I have downgraded to stable versions, I have gone to a debloated stock rom (which worked perfectly fine but who likes touchwiz android 4.1.2?) and back to AOSPA, I tried the latest Carbon nightly rom and the problem persisted, I have wiped my internal memory, cache, davlik, etc. multiple times. I am at a total loss as to what I should do to fix this issue. I'm currently running it on 4.6 beta 1 and I still have the issue.
I really love my GS2 and I don't want to part with it or have it running stock. Please help me.
I really appreciate it,
Chris
I've had the same issue , I was running the latest liquid smooth rom . I just flashed back to stock using Odin and all is fine on the stock rom . I just rooted again and am hesitant to install another kitkat rom for fear of this calling issue ........ Anyone else with this problem ?

I am also getting this problem on Slim 7.8....must be an audio-caf issue....Can someone go back to an old KK rom (one from earlier months) and see if they experience the same issue? Preferably cyanogenmod
I flashed to stock rom via oden and spent the weekend with the phone and all was good , I flashed to the latest cm-11 with no addons , stock cm-11 kernal and after an hour or so I lost call audio again . We must have done something to the phone in a previous rom cause not many people are having this issue . Now I have flashed about 75 different roms with no issue , I hope someone finds the problem cause I'm not to keen on the stock rom !
I've seen posted that snapchat was the cause of the no call audio problem we are having , I flashed the latest liquid smooth rom last night , download all my apps that I usually do except snapchat and I've had no issues with the calling bug . All is working great .

M919UVUFNH7 Modem

Is it just me, or is the M919UVUFNH7 Modem for the T-Mobile Galaxy S4 (SGH-M919) terrible?
I have the modem alongside a custom cm12 lollipop ROM, and before flashing this modem, everything was working fine and dandy. Wanted to try out Android 4.4.4, so was forced to flash the NH7 modem...BIG MISTAKE.
The phone would heat up for no reason all the time, the battery drain was ridiculous, my calls were always dropped and people couldn't reach me, and I was constantly getting dropped signals...
Anyone else experience this or have a fix? I hope I don't have to flash this modem for TouchWiz Lollipop ROMs...

[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

(req) modem.zip

Does anyone have OOS or h2os modem in a zip form? Want to flash it over cm13 to get better reception!
????
Thought of flashing the OOS modem with fastboot on to cm13 but don't know if it's safe.

I read over at sultans ROM that someone flashed it but don't know how well it worked out I get very bad signal on cm13 roms
Also wondering the same. I'd do it myself in fastboot but don't know the commands for flashing files like cmnlib.mbn, pmic.elf, etc. I know NON-HLOS.bin is modem at least.
Cm modem is same as oxygen os modem.
CM never modify modem or bootloader stuff on 3rd party devices.
They only do with Cyanogen os devices like oneplus one.
Also cm recently updated fw (modem bootloader etc) to latest update oos 3.2.2
.
Even if you need it, you flash this

If you flash it please let us know how it turns out.

But I thought CM never modifies Modems?
Did it work?
i somewhat got better reception i dont know if it was a placebo but it seemed better to me
I always wondered why I seemed to get worse coverage on CM. Places where I used to get 4G I now go down to HSPA+ or even HSPA. I would be happy to try the modem but I am out now. Will update the thread when I get time to flash later

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.
