E975 no signal and restart after 1 minute working!

Hello friends,
I've install CARBON 4.4.2 ROM on my LG E975 after that when camera force closed I restart phone, but it didn't boot up! Then I try flash another rom but any rom didn't boot up at all except official CM11, but it didn't detect sim card! So I decide to flash official KDZ with flash tool, after flashing KDZ it boots up but still didn't have signal and also IMEI is unknown!
As I checked it seems the baseband problem and unfortunately I don't have backup of my EFS partition
First I want to know is it baseband issue and where can I find E975 baseband and how to flash when bootloader is locked?!
Another strange issue is that after flashing KDZ when I turn on phone, It works but restarts after 1 min and it repeats...!! What is this problem for?
Thank you all in advance

I have the same problem with my E977 Optimus G.

same problem!!!!!!!!

False information shared by @Ernesto0023.
Following this guide will get you a secure boot error when attempting to boot into recovery. Even so following this guide is impossible because root is required and OP has no root on his kdz flashed MM.
My recommended solution would be reverting back to kitkat via kdz. If unfamiliar with the method follow this guide: http://forum.xda-developers.com/showthread.php?t=2785089
After reverting use the guide from post above: http://forum.xda-developers.com/lg-g3/orig-development/recovery-twrp-touch-recovery-2-8-2-0-t2966129
to flash TWRP.
Then fell free to flash whatever you want in TWRP. If stock lollipop ROM is you what you desire, download zip from here: http://forum.xda-developers.com/lg-g3/development/stock-t2961073
if stock MM is what you wish for download zips from here:

You can't install it because you don't have root and it is not for MM availible yet

But with root and installing over ADB should work, or not?
I mean root isn't a Big Deal on the G3
Edit: Sorry, now i recognized its the unrooted official MM - maybe to much partying yesterday

Yeah
Even so if his MM would somehow be rooted it was still kdz flashed so it contains
MM bootloader. That equals BUMP not working.
Hope you had fun.

Happy New Year to everyone here!

My phone doesnt want to downgrade. I stuck at download mode. I put my kdz file to lg flash tool and start it. After starting, lg mobile support comes and analyses phone. After that it says Upgrade stopped due to an error. I flashed mm yesterday! Phone opens normally everything works. No problem on recovery too (stock one). But i cant downgrade to lollipop! Please help!

Now, you flash TOT file 10x again with TOT file.... but dont change file DLL you have....
Download... file DLL fix...

Running the good ol' KitKat 4.4.2 Need guidance to update

Hi I just bought a LG D855,
It's currently running the old KitKat right outta he box. Build Number: KVT49L, Software Version: V10n-GLOBAL-COM
The phone is missing the Update Center and thus I don't get any OTAs, I've decided to flash a custom MM for the phone. However while I try to flash TWRP via Flashify, it reboots into Fastboot and I see no sign of TWRP. Is there a specific TWRP I have to flash for KitKat?
Also, should I first update to LL and then to MM? I'd like to use any custom MM rom close to stock there is.
Your suggestions will be greatly appreciated.
Kind sirs, pray link me to the ROM that's closest to stock for any suggestions you may have personally. :highfive:
Thank you so much in advance.:victory:

Now that you've asked to check if it's D850 or D855, please check the image attached. IMEI sticker says D855, so does IMEI Checker but I can see D850 written on the sides by the camera. Can you please confirm?

Hey thank you so much for this! I really hope I found this earlier. I can't boot into stock recovery though. It boots into fastboot. Do you think I should try installing the Bump'd version of the D850 TWRP? I don't wanna brick the device :crying:
