Hello experts,
I need an explanation for the following issue:
- M919 flashed via Odin with NK2 stock firmware
- flashed TWRP via heimdall
- flashed Mokee firmware via TWRP
- baseband is changed to M919UVUFNB4
Now I flashed my wife's M919 which is on M919UVUEMK2 with Mokee but the baseband stays at MK2. Why?
Do I need to flash her phone to NK2 and then flash Mokee to get the M919UVUFNB4 baseband?
Why would you want NB4 baseband?
You may have had mismatched baseband /bootloader on your phone to begin with.
You should always have the latest modem running NH7 or NK2, even if you downgrade bootloader.
Pp.
The point is why was the baseband downgraded when I flashed Mokee on my phone but not upgraded when I flashed Mokee on my wife's phone?
Mokee roms will not install modem or change firmware, these are not included in the rom.
Your baseband must have been at NB4 before you flashed mokee.
Its possible that when you flashed the stock firmware the modem didn't stick and stayed NB4.
Your wife's phone had the matching baseband /firmware already, so it stayed the same.
All you have to do is flash the nk2 modem on your phone using Odin and you'll be all set.

@PanchoPlanet: Yes you are right. While flashing the stock ROM NK2 the modem didn't stick. I had to flash it 3 times on my phone and 2 times on my wife's phone. Now they are both on NK2 baseband. But unfortunately that didn't solve the low WiFi signal on my wife's phone...
If you can see a side by side comparison of both phones on the same wifi network and one has more signal than the other, you may be having a hardware issue with your wife's phone.
Hardware related could be the physical radio on m/b or the antenna wire.
Find a wifi analysis app in the play store and run it on both phones and check your readings.
If they match it could just be that the displayed value could be off.

hi guys. my question is should my baseband be MDL for a MDL rom? I never did the tmo software update to MDL but rooted and started flashing right out of the box. For the most part I've had pretty good luck flashing roms but I see most roms are MDL which Im still on the original MDB baseband even after flashing several MDL roms. My baseband stays the same. Off topic I noticed my system settings about phone does not show what modem I'm on. I'm confused if I were to flash (haven't looked into in yet) a new modem. How would I know which modem I'm on? I feel like I should be on a MDL baseband but am skeptical about the difficulties regarding root. Anyways is it possible to flash a new baseband like I would a modem or kernel? Or should I just odin a MDL stock rom with root injected? Then start from there? I had trouble getting root and a recovery on my friends phone that had the update so I used odin to go back to MDB because that was the easiest solution for me at the time. Silly question but is the modem and baseband related in any way? I guess what I'm asking is what do you guys recommend? Are you still on MDB like me? Or is MDL a must?

If you started flashing custom stuff back when MDB was the latest update; and you haven't manually updated your baseband... then no, you should still be on the previous baseband. Also, your modem should be what your baseband is.. MDB. I know that if you flash ROMs in CWM/TWRP you aren't getting the modem/baseband. If you just want to flash a new baseband/modem, check this thread out. I will say though, unless you are experiencing problems with the MDB modems, there's no real reason to go changing it.
I've been reading around lately and it seems that there is a new modem/radio (excuse my improper use of the terminology) released called NH7. I believe I am running NB4 and apparently NH7 is more stable and improves signal related issues. My questions are: how do I flash the modem/radio, should I flash the modem/radio, and if I do flash the modem is there any way to restore it back to my old one if anything goes wrong?
If rooted you install new modem and if you don't like it you can go back to your old modem while using Odin on your PC.
Pp.
Remember the modem is actually two parts. The gsm modem (modem.bin) can be flashed in Odin and if you don't like it you can flash the old one back. The LTE modem ( non-hlos.bin) is tied to the boot loader and once you update you can't go back. Mismatched boot loader and LTE modem causes assorted sound/WiFi etc woes.

Hi.
I'm really out of the loop for flashing to the latest rom. I'm still on 4.3 Darthstalker Version X1. I want to upgrade to the latest 4.4.4. I've try flashing a few roms but I couldn't get the wifi to turn on so I want to know what I'm doing wrong.
I've flashed the NH7 modem.bin from Shinnyside's thread. I didn't flash the non-HLOS file because after flashing just the modem.bin file I can see the NH4 modem is sticking and everything still work on 4.3. I then flashed a few different rom but I couldn't get the wifi to turn on. Is it that I'm getting this problem is because I didn't flash the non-HLOS modem? If I flash the non-NLOS file, will it solve the wifi problem I'm having?
I also read some post that I need to update to the NH7 bootloader (i'm still on the mk2 bootloader) for some 4.4.4 feature to work. How do I do that?
Thanks in advance for your help.
Either try a different kernel or update to NH7 firmware, then flash ROM

Any custom kernel like ktoonsez or alucard for example.. Also make sure you update your modem if you don't want to update to the latest firmware
So the other day I tried to install a new modem on to my phone. I'm running CM12 on an S4. (MDL bootloader)
I installed an NH7 modem...and it worked, and surprisingly I DO get better reception.
Except now my sound doesn't work...and I can't watch videos.
Any ideas on how to fix this?
Flash MDL NON-HLOS or flash full NH7 firmware. NK2 is the latest FYI
I'm trying to use galaxsim unlock to unlock my I9195. The app says that I need a baseband ending with MJ7 or older.
At the moment the phone is on stock firmware
I9195XXUCOD3, which is android 4.4.2.
I have tried using Odin to flash two different modem files, one is a MJ7 modem file that I downloaded on its own, the other one is one that I extracted from some older 4.2.2 firmware. In both cases they flash successfully, the phone boots up, but there is neither mobile nor wifi connectivity. I assume that this is because the older modem file is not compatible with the newer firmware? I have successfully extracted modem files from stock ROMs and flashed them in the past, so I'm fairly sure I'm doing that bit properly.
I have also attempted flashing the older 4.2.2 firmware in it's entirety, rather than just the modem file, but it won't flash because the bootloader is older than the current one.
Any help for how I go from here would be greatly appreciated.
edit: i have also now tried flashing the I9195UBUBNE2 brazilian firmware that allows for downgrading from 4.4.2 to 4.2.2. even with this firmware, there is still no connectivity after i flash the MJ7 modem. so as far as i can establish, any MJ7 or older modem is not compatible with the later bootloader?
