HELP IMEI Lost

My Nitro's imei was lost in between flashing Roms, I did not have an imei backup, I've tried the temporary recovery solution in the lu-6200 forum with no fix, I can no longer access cellular network or data. Would appreciate anything right now as I really don't want to have to buy a new phone

Have you tried the LG update Tool ? If you dont have a Ginger Bread rom .Try the unbrick method up to when you flash the korean GB version then run the LG update tool to get stock ICS and see if a factory restore would reset the imei .Honestly I have done havoc to this phone and havent had imei messup .
Actually doing the official update right now, I have done havoc to mine too, I've flashed countless amounts and unbricked at least 5 times. I guess the phone finally got sick of it and quit on me
EDIT: after doing the official update my imei is still missing

Try in dialer *#06#.
Do you recall the steps you took to flash that resulted in this ?
Flashed via CWM from HoNo's official ICS to CM9 stable doing a wipe of dalvik and wipe of data/cache

To avoid a situation like this is there any current way to back up my imei? (Don't mean to hijack)

There is no way you can get it back, but you can restore some partition's data from other cell phone, use other people's imei.
I would just send it to LG to repair and/or replace.

Sir i did that but it displayed IMEI: 0
I'd like to make an important note that I flashed my phone twice using the lg official update tool, that the second time I did it I selected recover phone option and entered my imei, after that around downloading at 4% I disconnected my phone and after it started up my imei had returned! However after a reboot of my phone it was lost again, I repeated the steps several times to get it back and it has not recovered again. I have also let it perform a complete flash after entering my imei and it still has not come back
EDIT: My IMEI occasionally appears giving me a connection to the network however I can only receive texts, no calls, SMS, or data. Then once I reboot my IMEI is gone again. Another note is that I can not disable the radio no matter what I try.

thanks for your attention, when I did the repair I was on stock UVDLJA, saw the reboots then updated to stock UVDMD5, the reboots continues so I rooted and flash through TWRP PAC-MAN Rom and reboots still here
Did you update using Odin, or flashing a rom?
Did you factory reset?
Are you absolutely certain you restored the imei correctly?
Write down what it says for the imei under about phone, status. Then compare to what it says under the battery.

I updated it using Odin, I've made many factory reset even knowing Odin erased all partitions, I repaired using Z3X box imei and everything match with label under battery, right after the repair sometimes after suddenly reboots it ups with unknown baseband and null imei and in the next reboots like a joke everything, modem and imei appears I've made the repair using the box three more times thinking was about firmware versions but didn't help
Oh ok, ive always wondered about the boxes thst are out there. You're the first I've heard of someone actually using one of those.
I may have something you can try though. Watch your PM's, just give me a few min on it though.

The fix is to repair IMEI by NV
Hi! I know this subject may have been closed but I have the same problem too.. I've repaired my imei and then after last reboot this loop started. Opening.. lockscreen (1-2 sec) and then shutting down. After that, going to TWRP. I use Orange Fox as TWRP. I have never installed any roms. Just rooted. My phone is Xiaomi K20 Pro/Mi9T Pro. I tried many times wiping data,cache,dalvik.. and factory data. But It didn't help either. Can I ask what is repair IMEI by NV?

Unfortunately you will have to flash the stock image for your Note 2 , to recover your modem information, it happened to me once, and this was my only working solution.
After you do it, you root and install a recovery , then wipe flash everything and install the rom you want
