Hi there.
I have a big problem with my G2. When I changed ROM LG-Flex CM My phone is stuck on the bootlogo and started up again. After installing the LG-Flex does not recognize the internal memory, IMEI and baseband.
Please help me.

Flashing back to stock will fix those issues.
Flashing "stock" europe open D802 does not repair that, still baseband unknown, now I'm downloading and try to flashing my real stock rom, via LG Mobile Support Tool.
If that not help, I don't have more ideas...
unfortunately, after restore real stock firmware, baseband is still unknown.
Please, help me repair my phone. I can't unlock developer options, when i tap on firmware version, my phone is freeze and restart.
Now I root G2, and flash TWRP, but flash new modem, nothing change.
I think at this point you either need to restore a efs backup (if you have one). Or use LG's pc software and try an 'emergency' repair/recovery. But for that you'll need to at least know your IME number. As the software asks for it.
No ROM's contain efs data. As it's unique to each phone.

Yeah i think nomad is right, you somehow have completely lost your EFS partition...i had the sam isuue as you and flashing to stock fixed it, but i probably still had my EFS. Did you make a back up of the stock rom at any point? Because if you restore back to that it should restore the EFS and fix your problems.
Unfortunately normal backups don't backup the efs partition(s). So they would have had to have done a specific backup just for that using a 3rd party backup script in recovery.
But using the lg software and knowing your imei you might be able to recover it. Well recover is the wrong term. What the LG software will do. Is recreate that partition using your imei.

Had the same issue with the same Rom. I tried a bunch of things for a few days but couldn't find a way to fix mine. I got a replacement.
I did this with my new G2 and only flashing Roms for my phone now.

I flashed back to stock but think I was still rooted. I talked to a few long term T-Mobile customers and they said it doesn't matter. I just took it into the store and played dumb. hehe

I am hiaving the same problem... Flashing my original KDZ two times and still baseband unknown and IMEI Null
When i flashed VanirAOSP 4.4.2 on my xcover 2 everything else worked like it should but sim card stuff.
I lost imei and baseband was unknown.
Cant make a phone call or anything else related to sim card but got those back when restored old backup of stock rom.
I did just like instructions said but everytime when i flash vanir i lose those.
Tried efs backup and restore but it didnt help.
If someone knows what im talking about and knows how to fix this skomer would be more than grateful (dead) :fingers-crossed:
Same problem here. Flashing stock rom will fix that.
Are you using the correct version of CWM that the developers suggested on their thread? It's most likely that or you have a mismatched baseband. You should be able to use Odin to install the latest one for your region to bring back your service. This is why it's often suggested to back up your EFS before installing custom rom. Seems to happen a more on Samsung devices with non TouchWiz based roms. Luckily, this seems like an easy fix, but there's a chance of losing your EFS partition with stuff like this, and that's a whole new world of trouble.

I got the same problem except I flashed the cm10.1/10.2/11.0... lost sim, IMEI, baseband (I´m a noob btw).
Went back to stock (rooted with cwm), works fine though. But sure as hell would like to cm 11.0 to run with a working phone,
it was really smoothe...

its nice to know that im not the only noob in here, keeping fingers crossed and dreaming about the day when we get our skomers working perfectly.
I'm stricken as well. I tried both Vanir and CM and had no signal on either of them.
I'm using CWM 6.0.4.6, wiped all filesystems I dared (/system, /data, all the caches I found). I haven't flashed modem fw though (how, is there any link for firmware?).
After the flash, I can see IMEI in phone information, but I don't have any mobile signal. Flashing back to stock firmware resolves the signal issue (well, last time I just used CWM's backup functionality and it worked like a charm).
same here
has anybody a solution for it? my imei is empty after flashing something. i tried to backup my efs partition but dont know if its right. Just create a tar file of my efs partition.
Hello there.
It's the same for me. Every time, I install vanir, my device looses it's IMEI. I install it with the modified CWM by the Dev without any errors. Everything seems to be OK except the IMEI. If I go back to XXAND2 by Backup, everything is OK again. I also tried an efs backup, but in vanir I have problems to get it back, "error, empty archive" it says. I'm really confused about that.

Got my phone back from repair couple days ago and its brand new xcover2 but still the same when flashing =( ... i tried efs backup and restore but said it cant be found or something like that. And im 100% sure i had the backup on my sd and its still there but it is what it is. Im going to wait for someone smarter than me to figure it out and keep the stock**** for now.
Holy cow! I did it.
I got everything working exept baseband it says now xxxx but that doesnt bother me cause i can now make phone calls and messages.
Dont know about how right my method was but it worked, i copied efs folder and modemfs folder from stock rom to my ext sdcard and flashed vanir then with root browser i deleted everything from those folders and replaced with copies i made... sounds weird but im happy :good:
Hm, seems to be a solution. This is my biggest problem, too. What about updating Vanir to a newer built, when you have vanir already installed? Have you tried it too? Do you have to copy the efs again?

Yes i did update it and there was no need to copy/paste again. But im confused about baseband : XXXX, could that do harm later on?
Its good to keep the copies on extsd cause if messups happen u dont have to fight with them backup things which didnt work for me.
Sounds simple. I'll try it next time. But do I have to clean the Dalvik cache too before installing vanir or should I just do the wipe?

It's like someone doesn't want me to use this ROM ? I tried your hint and copied efs and modemfs to SD, installed Vanir and GAPPS, copied efs and modemfs back with Total Commander, restarted and all was the same as before - no IMEI.

No, I just overwrote it. Don't tell me that's it. ? Dammit, I didn't even think about it. I'll try this next time.

Hi,
I have done a lot of research and tried several methods, but got nowhere yet and I was hoping someone could probably help me restoring my phone back to normal.
I was trying to install a different baseband version on my international N9005 (Android 4.4.2) with ODIN and it all went fine (a process that I have done a good number of times already). However, when I restarted the phone, I got into a boot loop and after wiping cache and dalvik I got the phone to start. The problem is that the phone is now showing baseband unknown and IMEI null, which somehow also causes problems on the whole system, the phone goes a lot slower, the camera does not work, the clock app either, etc.
Just so you have the right information, I live in the UK and I originally had modem version XXUENB1, after which I have tried several others such as XXUENC2, XXUENF2, DXNE3 and ZHNE6, being the latter the last I had after trying to install version XXUENE3, which is the one that left my phone out cold.
I do my backups using Philz recovery, and I have a few EFS backups using it, which I have tried to restore with no luck. The EFS backups have 4 files ('efs.ext4.tar'; 'efs.ext4.tar.a'; 'nandroid.md5'; and 'recovery.log'). Also, I have another EFS backup that I did which is one file only, 'efs_20140531_122400.img'.
I have also tried restoring old full system backups and a brand new firmware via ODIN but I got the same result (I haven't yet tried a full restore with separate CSC, PHONE, PDA, Modem and PIT files as I am waiting for the files to download). Again, I have tried installing different baseband versions with ODIN which I know that worked in the past, but no changes.
I do not know what else to try. Anybody has any ideas?
Thanks in advance.
Cheers
I would suggest to flash latest UK NF4 if you havent't do so

Been using rooted stock roms for forever, but found myself lacking the need for wifi calling as of late, so I've been open to flashing something with more pizaz. I tried flashing both Dark Unicorn and Blisspop today, but neither would allow me to enabled cellular networks (it would toggle on, then back off by itself a few seconds later). I'm on T-mobile, I tried all three APN's that were pre-loaded. The notification drop-down would show it was connected to T-mobile, but it wouldn't show a data signal, and had an exclamation point over the cell signal. Anyone have suggestions on how to rectify this, or is this expected?

Tried each only once, will try again. When the first didn't work, I tried the other rom. WHen the second didn't work, I restored back to current. With each flash, I did advanced wipe, doing system, data, cache, and dalvik
Will try them again, wish me luck

5.1.1 roms all have the ! signal next to it. so you saying that you cant connect to internet using data.?
they to download hybrid bootstacks, you know the procedure,
wipe all, install hybrid bootstacks, then go into main menu then reboot into recovery from recovery then, copy rom into phone flash rom and gapps.

When you say "copy rom into phone", it seems there's a chance I'd loose data on internal storage? :-/
And what about if I want to restore back my current rom - is there anything that needs to be undone? (thanks for the replies, btw)
I'm at twrp 2.8.6.1, fyi

i recommend balstagator twrp to prevent display damage cause of heat.http://forum.xda-developers.com/lg-g2/development/twrp-twrp-2-8-0-0-kernel-f2fs-tools-t2898705
when in recovery yes delete all if you have stuff in your phone if they are pics just move them to pc, if those are apps use titanium paid app that will back up, app and data like whats app all conversations. if its only like pics videos moved them to pc, if apps using the free version of titanium back up ypu cant restore batches, musst must do one installation at a time..
its always better to install a fresh installation that means wipe all.
to be honest i dont do nandroid that is what is called in twrp back up,i think i did once and it didnt worked, it does work if i want to mess with rom and if it fails or i get problem doinga restore brings back the way it was just like a restore point. but am not really sure if you wipe all and do a nandroid restore it would bring back the rom, as am typing i did one am trying a ifferent rom.. ill see if it works..
ok i tried 2 roms 1 stock custom, and cm13 so i just restore my nandroid and it worked. ive selected all in back up. wipe all then copy back the twrp back up and restore it. it works ...
ok i got some folders missing like dcim.well most just copy important folders like music videos and pics to pc then once you restore it copy them back.

Tried it, didn't work. Do I have to be on stock for it to work? I reverted back to Pixel Experience since stock was having the same issue. The version of stock I was running was TWRP Flashable Oreo 8.1 w/ Aroma installer, if that matters.
Also there is a possibility that I may have wiped the QCOM partition on accident, I honestly have no idea. Although I've gotten the hang of this whole flashing roms thing now, a few days ago when I first started doing this, I had no idea what I was doing. lol

I backed up the persist and efs and when I boot up after restoring them the phone gets LTE signal for maybe 30 seconds then reverts back to 3G. ?* Maybe I already somehow messed them up before backing up? When I check my IMEI it's not zeroes though... it looks how I would assume a real IMEI would look.

Maybe you could try flashing stock ROM from fastboot--pc as it will flash all modem and other things too, so consider flashing from pc.
