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 guys, im in a very deep trouble since yesterday, i was testing trying to flash Renovate Rom on my S8 Plus SM-955F, unbranded exynos version, Ive test before almost 5 o 6 roms without any trouble, but suddenly I got a bootloop, so i decide to restore the backup I made before i was start to flashing any rom, along tow days ago. The backup apparently restores well, but it last only about 15 or 20 seconds, I rebooted and doesnt get pass from galaxy s8 logo at startup; so Ive restarted again , got to thw twrp and tried to flash again another rom, BatStock in this case, phones starts without a problema, but now network doesnt work, and Ive lost my IMEI , baseband, and i guess all EFS folder.
Apparently the backup on the sd is corrupt , and I tought when i tried to restore the backup, It get all erased and messed up.
Does anybody have some idea to solve the problem, Ive tried to restore the efs backup from the backup alone, apparently it restores, but i continue without imei.
Please someone help me, Im getting crazy aboyt that, ive buy the phone trough and Internet page, so I dont have warranty in my country Argentina.
Thanks in advance.
Any idea?
Please Help me folks
Try this way via Smart Switch
Hi, search in S7 edge forum, you have a guide to recover the IMEI. Are you using an external SD for nand backup?

If you are sure that your backup was properly created, you can omit the md5 check.
There's an option in the TWRP settings.

From the screenshot it looks like you are trying to restore the cache.
Can you try without it, and restore /efs ?

Restore the backup and then wipe the cache?
Always whenevr we restore, we should wipe cache/dalvik cache then reboot.
Or try smart switch after putting phone into download mode and it does it's job well.
Some files have gone corrupt but majority Looks fine. Wipe cache n reboot n let us know

Guys, do you know If it's possible to extract the efs partition or efs folder from the twrp backup, it's maybe posible?
And how I can check if the backup is allright or if it's damaged.?

I wanted to flash stock rom but by mistake I flashed a wrong version of it. I later found the actual version of rom i needed and flashed it. Everything is working fine but I'm not getting network services. Is there a fix for this plz help
How is that being "hardbricked"? When it is "hardbricked" you will have only a flashing led, and not be able to boot into anything, much less be able to flash a rom.
