Question: After flashing a different Kernel baseband become Unknown / No Signal - G2 Q&A, Help & Troubleshooting

So i installed a different Kernel, to be specific Healthy Honey on my D802, using Resurrection Remix latest version. But before i was using a different Kernel which is render. when i tried to flash HH, baseband become unknown on About and i can see there's no sim icon on top.
Things i've done
Flashed KK Basedband = Still Not working
Flashed JB Baseband = Still Not working
Flashed both bootloader / bootstack which was working before with render kernel = still not working.
Flashed Render Kernel (which was working before) with both the KK Baseband and Bootloader/Bootstack = Still the Baseband version is unknown.
How can i fix this? Thanks
EDIT:
Also IMEI Information is now unknown / bluetooth also but wifi is working.

No its fine working on stock rom but when i flashed PA rom it does not read the baseband version. Maybe soft bricked?
EDIT: Before it happen i dirty flashed my rom via twrp 2.6.1.0 I am on PA 3.98 then the baseband signal still going fine then i dirty flash 3.99 and i got unknown baseband version. Then i reverted back to stock rom (factory reset) everyting seems work fine. But when i flashed again PA 3.99 got unknown baseband again. Maybe TWRP causing the ussue . Do you have flashable 2.6.0.0 zip twrp recovery? thanks sir.

I don't think there is anything you can do at the moment.
You're not the first with this problem. But I haven't seen any solutions yet.

AT&T G2 D800 - All Cloudy roms are broken

Hello everyone,
I just received an unlocked AT&T G2 today. I rooted it with rootstump and installed twrp with autorec, and then decided to install CloudyG2.
Instructions say to wipe, then install KK baseband file, then the rom. I did this, and ended up with a lot of basic functions not working. Things like auto rotate, auto brightness, no 5 GHz internet, and no signal were some of the things not working. Searching the thread said that you need a kitkate baseband file, which I already installed.
I try to reinistall both radio's from
here: https://www.androidfilehost.com/?w=files&flid=12880
and here: http://forum.xda-developers.com/showthread.php?t=2451426,
and both of the most recent versions do not do anything.
Thinking it might be just the rom, I wipe, install the most recent kitkat baseband file here for D800: http://forum.xda-developers.com/showthread.php?t=2451426 and try cloudystock 2.7.
Same problems
What am I doing wrong? Is the baseband file not installing correctly? I believe the original baseband was 10D or something. The stock firmware was 4.4 when the phone came.

I can only recommend flashing the modded 4.3 bootloader (12a?) and flashing BlissPop or the like.

You need to flash a Lollipop modem. Or you could reflash the Lollipop firmware.
I wouldn't flash the link above you. He has no description at all of the file.

Just as OP, I downgraded to kitkat, in my case because of the terrible battery life S4 gets in lollipop. I have spend days trying to fix this, I have tried all kinds of wipes and ROMs, until I got a decent lollipop ROM and flashed just the modem image, and the problem was fixed!
I thought I had wiped my IMEI, because of the IMEI null and Baseband UNKNOWN issue, but as soon as I flashed the corresponding modem, I "got it back". I do recomend you however, to backup your EFS partition, because apparently you *can* wipe your IMEI when you flash ROMs.
