LG G2 Intl. Baseband unkown.

dunda92 · Jan 12, 2014

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.

NomadCF · Jan 13, 2014

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
