If you want to revert to another modem from the OPO Lollipop alpha modem, flash the FULL 44S modem found here > http://boeffla.df-kunde.de/bacon/modems/

After flashing this file, you can flash whatever modem you want, like the CM 1128, that many users have been using.
[ONE General] trixje:
modem.bin

[MENTION=3209971]cam30era[/MENTION] what is the difference between the full and the normal modem file?

If you flash a modem and you flash it with another one, it get's replaced? or am I wrong?

The full file contains a NON-HLOS.bin file, that is the modem file I am correct?

I do:

fastboot flash modem NON-HLOS.bin

fastboot reboot

Question: Why need to flash another modem after flashing NON-HLOS.bin?

Can't you flash directly to the modem you want?
[ONE General] cam30era:
[MENTION=3871248]trixje[/MENTION]

The OPO alpha modem changes some partitions on the phone, which need to be reverted for the older modems to work correctly (my understanding).

NOT fastboot flash.

There are custom recovery flashable .zips.

Edit: sorry, but I can't answer your other (more technical) questions.
[ONE General] andip71:
The NON-HLOS.bin file is the modem itself, true.

However, jumping from CM11(s) to CM12 changed apparently more.

Hence, I just updated my modems file to also flash the rest of the "environment" back according to the firmware the modem was developed for.

So it flashes not only NON-HLOS.bin, but also emmc_appsboot.mbn, logo.bin, rpm.mbn, sbl1.mbn, sdi.mbn, static_nvbk.bin and tz.mbn.

Don't ask me what is in that files, I guess nobody know lot about it.

However, cannot be wrong to flash the environment around the modem (of course not the system itself) too when jumping between CM11(s) and CM12.

Hey I just wanted to thank you for your work. Today I was confused because my phone was acting weird and I had no idea why. Last night I had put a CM12 nightly on to test and then restored my CM11s backup and went to bed without knowing about the whole modem thing. I posted asked for help and Timmaaa responded with an explanation what I did wrong, and mentioned this thread. After reading this and several other threads I flashed back the 44S modem but I also noticed that the CM12 nightly modem zip everyone has shared contained more than just the modem bin. So I kept reading and finally found you, your website, and your Full modem zips.

I now have both on my phone and will be flashing them alongside my CM11s backup for daily use, and the CM12 backup I play with at night and on weekends.
[ONE General] rkuijpers:
Alpha modem seems to work perfectly in ColorOs 2.0.42, at least for me it does. I see full bars at places I never got full bars before, although I must admit I never really did any research on it.

But so far so good! [emoji106]

So it looks like the latest CM12 nightlies are using (at least part of) the same modem partition files that ColorOs is using?

[ONE General] dazadaza:
Hi!

First a basic question, that might have a non-basic answer; what is the modem firmware responsible for?

I'm asking this because my issue is this; I can get a good(well, about -75 - -80dBm) signal on H/H+, BUT it keeps flapping between H/H+ making it almost impossible to push data over the connection. Also the signal gets lost for a while and then comes back. Looking at the Network Signal app the Cell IDs tend to change when this happens...

Does this sound like an behaviour a different modem file would alter?

I've had this problem with the "stock" CM11s latest OTA, CM11-NIGHTLY and now CM12-NIGHTLY. The nightly using the modem-files supplied by those zips... Seems to get a bit better dBm-values with CM12-NIGHTLY though...

/dazadaza
[ONE General] Heisenberg:
The radio/baseband/modem is responsible for wireless activity on the device, like cellular signal, bluetooth, proximity sensor (but not WiFi). Your situation is definitely something that could be fixed by flashing a different radio. It's hit and miss though, you'd need to test each modem thoroughly, looking at the signal strength and also battery drain.

Has anyone tried the CM12 modem in this folder?

On rooted 44S, it works fine until I press the lock button. Then, the phone refuses to wake up until I hard reset.
[ONE General] jdfeos:
Great!
[ONE General] Heisenberg:
That's because you can't use the lollipop modem on CM11S, it breaks your proximity sensor. You have to revert, as per the post you quoted.

Transmitted via Bacon
[ONE General] 3l3tric:
Oh, OK. I didn't realize that.

TBH, I saw the proximity sensor mentioned in the thread, but I didn't realize that that would affect the lock button.

All is well, I flashed the 44S FULL .zip and the 11/28 zip.

The reason I'm looking for another modem is my phone is in areas with no service a lot and I find that the modem "Locks up" and quits searching for a cell signal until I reboot the phone. Even airplane mode won't turn on sometimes when it gets to this point.

I saw the ColorOS modem mentioned earlier in the thread. For that, do I just need to download the whole zip and extract the HLOS.bin file containing the modem and use TWRP to install that? Or is there more to it?

EDIT: Haven't tried it yet, but I downloaded the ColorOS ROM and extracted the NON-HLOS.bin file and the whole META-INF folder. From the other zipped modems, it appears that these two files are what's necessary to update the modem. I also removed the "Android" folder under META-INF\com, which wasn't present in the other modem zip.

Is this appropriate to flash now?

Is there a modem compatible with 4G LTE frequency band 800 mhz :confused:
[ONE General] zephiK:
That depends on hardware of the device, not on the modem.
[ONE General] Trinytix:
In this case that is a software problem. :good:

The OnePlus One hardware fully support 800Mhz, it is only a software problem.

It was already said by the OnePlus support to the French a community because in France the 800 Mhz is used. Except OnePlus has no plans to update to overcome this problem because it has concerns only a small part of global users. :crying:
[ONE General] zephiK:
According to official specifications as listed on, http://oneplus.net/one#specifications

The OnePlus One does not "fully support 800MHz." A modem cannot provide extra MHz to be utilized, its within the hardware, not software/firmware.

800MHz in LTE bands is Band 20. OPO only supports LTE Bands 1/3/4/7/17/38/40.

Thansk for the answer, will have to try a couple different and see if there are any improvements!
[ONE General] derekk75j:
I don't know if you must flash rpm.mbn, sbl1.mbn and static_nvbk.bin too. I'm not sure, because I see the script of 44s modem flashable zip, that installs those other files, the alpha modem only static_nvbk.bin. So, I don't know if installing only NON-HLOS file will be enough. With this rom I have the best signal i ever had, in terms of stability. Compared with another opo, same carrier operator, same area: mine had always best signal, more stable. I would like to know if somebody had same impressions.
[ONE General] 3l3tric:
Hmm, OK.

Would it hurt anything to flash the zip as is without those files to see what happens?

Also, where should I add those files in at? The root directory, or somewhere else?
[ONE General] derekk75j:
If you install only NON-HLOS.bin will be ok, it doesn't hurt anything, but I don't know if modem will have same performance.

In the zip file of rom, there are all files needed, they are in the root directory

META-INF/
relic242/
system/
boot.img
emmc_appsboot.mbn
logo.bin
NON-HLOS.bin
reserve4.img
rpm.mbn
sbl1.mbn
static_nvbk.bin
tz.mbn

Question is: what file need to install?
[ONE General] 3l3tric:
I just tried using TWRP to flash the modem to no success.

I attempted flashing a zip compressed on the store setting with just the NON-HLOS.bin file in it and one zip compressed the same way with the META.ini folder in it as well. Neither worked.

Not receiving calls on CM12 modem

Anyone else having issues with calls not being received when running the modem included with CM12 nightlies? I didn't even notice it was happening for a few days, but I started getting several voicemails without ever having missed calls.

After testing, it seems like after my phone boots, I'm able to receive calls for several minutes afterwards. I'm not sure if the modem goes into an inactive state or something after this, but whenever I try to call myself after these first several minutes, I get a "subscriber is unable to be reached" message from my provider and the phone never rings. If I switch network modes (LTE>3G>2G), after reconnecting to the network my phone picks up calls again for a few minutes then repeats the same problem.

I tried a factory reset and the problem persisted, then I tried switching over to the 1128 modem and I'm having no issues with that, except for the occasional sleep of death issue which seems to be expected when using a CM11 modem. Just tried the new nightly modem that funCrash posted above and the problem is still there.

only if the rom contain a new NON-HLOS file (radio). Wipes from recovery don't touch other partitions (you can only wipe system, cache, data,ecc...) Es. bliss rom 1.8 doesn't contain NON-HLOS file , and if you flash it, radio remains the same. From 20/01/15 partitions of cm12 have changed and it need to flash new modem (NON-HLOS.bin) and partitions (emmc_appsboot.mbn, logo.bin, rpm.mbn,sbl1.mbn, sdi.mbn, static_nvbk.bin, tz.mbn) .
