DMH1 MODEM | Fixes unknown IMEI / No signal

This is a cmw flashable zip of the latest DMH1 modem for the n7100 for anyone who has updated to a DME6 rom and is stuck with no signal, no imei or a buggy modem...
This one seems to have fixed all issues for me. Before it used to be slow and speeds were all over the place. Now I get a steady speed when on wifi.

dhm1 is latest??

Yes sir, according to SamMobile it was just posted the other day for the 4.1.2 Turkey and Slovakia updates.
Although I would only flash it if you're having problems currently. If you did not update and got stuck with DME6 modems do not flash it.

@ What is it here for ****
CSC is not Baseband ( Modem is XXDMF1) in all Sammobile FW.
CSC is the Country...Hidden-senttings my Friend .
When you fix the other Modem ( Baseband) for the Note 2 and FW MG6 or MG1 than write not here is new Modem MH1....Ride.
The Problem with Imei is in MG6 and MF2 and finish.

Modem has absolutely nothing to do with WiFi. WiFi is handling by the kernel and a different chip from the cellular connection.

Exactly, this one is misleading
MH1 is not modem but CSC, it still carries MF1 modem. If you refer according to number then still MG1 is latest modem. But still i don't recommend anyone to update it except this one is for your region. Likely you will get best result for network on your own regional baseband not on latest of other region.

i like that XDA brings both the most awesome and amazing knowledge base, and the stupidest ideas missing even the most basic knowledge of what some people are messing around with

If there's no changes in this modem then comparing the files should give the same results and what I am seeing is major differences in the two files... It might have the same build name but it is not the same modem. Also, I know the issues I was having with wifi and now I am not. The modem is the only thing that was changed.

I had 'not registered on network error' when moved from 4.3 test roms to some of custom 4.1.2 roms. After flashing this zip, phone functionality works fine without error.
Thanks for sharing.

The reason is the modem is not a DHM1 modem, it's from a DHM1 rom however it does have changes to it compared to a different DMF1 modem.
The best modem is any modem before DME6, but if you're stuck using something after that then this one seems to be ok for me.

Dr Ketan,
I need your help to solve this problem. My Imei is ok by the serial number has gone "0000000". I had network but could not dial of message anyone, in other words "No Mobile Network Connection". I used the Azira's Patch and now I am able to make calls. Is there any way to get back the serial number back on the phone, without screwing up the IMEI. All this happened after the stability update OTA from Samsung.
Please Help.
Thanks.

Unfortunately there's never been a way to convert the Verizon addition to a developer edition as far as I know. But with S OFF there is really no difference because the device is completely unlocked and you can do whatever you please with it.

Can you link me to the exact one that you are running currently? I installed the 1122 build yesterday and everything was fine until I rebooted the ROM and I lost data completely and was unable to get it back. I heard of a few others complaining of the same issue. Have you tried to reboot your phone and see if data still working with wifi off? If so and it is please link me to it exactly which version you're running thanks

I installed it a hour ago. No problems yet

I have been wanting to convert mine to a dev for a long time, and there are two different posts out on the m8 forum for this but they only work for the gsm versions such as international, tmobile and at&t. And I"am sure there has to be a way for our verizon m8 its just finding it, as ours is a world phone being both cdma and gsm, even if it had to only run on the gsm side it could still work if they get the volte update pushed out as part of L then there would be no need for cdma for us and we could just totally run off verizon lte which is actually gsm.
So this may be a possibility in the near future especially. I myself not only want the updates directly from htc which are faster but I would prefer to never ever again have to run verizon software / firmware because all verizon wants to do is lock us all out.
At least all the other carriers allow htc dev to unlock the bootloaders but verizon just likes to be total asses about this, I guess they think they are too big for there britches, for this exact reason I really wish I could switch to at&t but I dont have coverage for them at home with zero bars maybe some edge coverage 1% of the time never enough to use the phone on, and verizon is not much better with only getting 1x data and no plans to upgrade.
So I"am with all of you on this I would like to convert my verizon m8 to dev also and ditch verizon having any control over my phone ever again, as I pay them for service and not to try to lock down my phone which I"am supposed to legally own with honoring my side of the their 2 year contract.
But for that matter you can buy a phone at full retail price and they still try to lock you down.

Flashing modems/basebands on G920F/i?

Is it possible yet to flash different modems/basebands? I am using a G920I on AT&T and would like to flash the AT&T modem.

Same question here. I have a G920F and want to flash a modem. I have the AOD9 modem.bin and I assume I just flash it with ODIN with CP but I don't really want to go ahead and do it without knowing that I'm doing it right.

No, I have it from a French rom, it seems to be the best modem I've used so far.

Funny cause I went to At&t and Verizon to check signal and there's are perfect.... I live in Alaska and most our towers are shared with At&t so the 920I should work on their network... But I can't recommend being the first to flash an att baseband on our phones.... Let me know if you end up trying it out... I was hoping my phone was just bad bit I've exchange 2 times already same **** reception
So you did notice a little better reception with the newer modem huh? The only thing I can think of is my S5 had LTE Cat 4 and this phone has LTE Cat 6 don't really know if that makes a difference... Probably not...

I attempted to flash ATT modem on 925F and it failed.
But not sure if I attempted it correctly. I flashed modem.bin instead of modem.tar.md5.
If somebody can get me the latest ATT modem in a format that is for sure flashable via Odin I'll try it.

Where did you get the modem? I'd like to see the g920a modem
Sent from my SM-G920I

I extracted it from the latest factory ATT firmware. The thread is stickied in General

I was able to flash the modem and BL files from "Latest Bootloader & Modem packages" thread on my 920F, but unable to use the AT&T versions. I'm also trying to see if I can get a signal reception improvement on my LTE AT&T SIM.

Any word on if there is any modems for sprint g920p? I've looked and looked and I can't find help anywhere...also, how do I go about finding the modem.bin? Worse comes to worse ill have to try an make one.. -.-

How did Odin report the reason of failure?
Have you tried other versions (not 920f)? If we can get back by flashing the original modem, I think it's worth trying. I know that 920F/T/I have the same baseband chip made by samsung.

I have a Sprint galaxy s6 edge unlocked and i use it for T-mobile. my LTE signal is so low at times. I was wondering if i could flash a T-mobile baseband and BL and just use tmobile roms?

Is there an update to this? Looking to flash AT&T modem on G920F. I have poor reception.

I got bad news for you. VOLTE and Wifi calling only works on android phones that has been bought from Rogers. I have the unlocked version from Samsung.ca and it still didn't work.
Correction: The only unlocked phones that work on Rogers VOLTE and Wifi-Calling are the iPhones.

Yes the volte is there and turned on but every call I make it changes to 3g or 4G. Wi-Fi calling is there as well but when I register it it say not compatible with my phone. Batstock rom. Yes twrp is installed.

i see.
next thing you want to try, make sure your build.prop product name matches that of the rogers phone.
also, my carrier disables feature if it detects root such as wifi calling. if you have magisk hide and an app for wifi calling uou may want to try hiding those apps from root.

I hear ya. I changed my build prop model name to my carrier brand which is 955W. I 'm also using magisk hide for other things as well. No luck. I will call Rogers tomorrow just to see what they have to say.

I already called Rogers tech and VOLTE and WIFI Calling don't work on Android phones that was not from Rogers. No matter what you do, its the IMEI number that triggers their system to enable it on their end.
Unfortunately all carriers including Bell, Telus, Fido, Virgin and Freedom Mobile do this.

if it trully is incompatible, it is more likely to do with the difference between th band availability between the international model and canadian model... a quick google search will allow you to compare band availvility between phones and what bands are used for the carrier.
i don't believe it though, that just makes it hardee for them to aquire clients with existing handsets.
