[Q] Questions regarding nh7 modem/radio

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.

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.

Need help - still on 4.3 MDL bootloader, I want to grade to 4.4.4

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.

Click to expand...

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

Explanation needed for baseband

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.

[Q] Installed Modem....shouldn't have installed modem.

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
