Hi,
I am getting a bit lost. I have a LG G2 which I recently upgraded to MM (last stable Bliss).
Before the upgrade I was using Stock KK , that worked fine. Now I upgraded the phone, and it looks like no SIMcard are working anymore. I tried several, they all give the dutch error 'kaartfout' (cardfold). When I check the settings, it tells me no SIMcard is inserted. But it is inserted, and it is inserted the way it should be.
What is going on?
What model?Maybe it was unlocked and with all the wipes unlock was lost?
LG D802 (is that sufficient information?)
I have no idea how to find out if it is currently locked.
Can it help to flash a new radio?
It's because your phone has a kitkat bootstack. What you need to do is go back to stock jb/kk, upgrade to LP -before rooting-, root, autorec, upgrade to the latest twrp and flash the rom. You can also flash the LP bootstack ( instead of going back to stock), but I don't recommend it, as it may cause problems.
Here are the two threads that will help you:

Hello,
Recently I have been running AOSP rom on the LG G2, I tried to recently apply the 4.4.2 update via the ripped LG Gpro in android developement. However to my own stupidity I did not follow instructions correctly already being on 4.4.2. The rom flashed however not correctly, with exsesive over heating and no sim connection as well as many other bugs. I have tried to re-instal custom recovery but cannot due to the 4.4.2 update. I then tried to flash a Kdz file via lg software to downgrade back to 4.2.2 but it will not flash as it connects and states that I already have the most up to date software even after adding the 4.2.2 file.
The phone is stuck on the custom rom, it is now rooted via the normal method, unable to instal a custom recovery and have had no look re-flashing a stock or another rom via software.
Overall goal is to get back to stock, and take it from there. Can anyone surgest any alternative methods to re-flash standard rom or instal a custom recovery to then apply a different rom.
Other information, phone switches on and can connect to a pc and recognised. No issues to this style of use but not able to be used a phone.
Any information would be great,
Thanks,
Jordan
Looks like we now must use the offline method described here

LG software update has blocked downgrade path using the Flash Tool. If you're on T-Mo you MUST flash back to 80110c, NOT g.
HI all. Bought myself a UK G2 the other day, came with 4.4.2 installed. I followed to guide to downgrade it to 4.2.2 (i'd rather keep it on that). After the .kdz flash (yes, it's the correct region and for the 16gb) it just says "no sim" all the time. Rooted, installed twrp, flashed the rootable kitkat zip that's in the forum, still no sim now I'm back on 4.4.2. Any ideas anyone? I need my phone for work so need it sorted asap.

Make a factory hard reset
Nope, still no good. Flashed both the official 4.4.2 kdz and also the 4.2.2
I'm having this same problem. I really need this fixed. I used this method to get root and now I have no service. It is very important that I get my phone working!
Edit: After several formats I tried a FULL format including Internal and System partitions then put the phone in Download mode and followed METHOD 2 of this guide.
So, first got my LG G2. Was on 4.4.2. Managed to get custom recovery on it, cool. Attempted flashing resurrection remix. Success, bootloop.
TOT'd back to stock firmware, 4.2.2. Managed to root device, and place custom recovery on it after multiple apps because I don't understand what the f*** "Loki" Is, or anything. So I attempted to flash 4.4.2 ROM, failed. Cool. Attempted to flash resurrection remix again, got aboot error, and loki-ifying failure of some stuff. Rebooted device, bootloop. Cool. So, how do I place lollipop on the LS980 4.2.2?
@edit, got LiquidSmooth 4.4.4 ROM on there from 4.2.2. Had audio error, flashed newer nightly of LiquidSmooth, got bootloop. Flashed KK Baseband from Cloudy's thingy for the LS980, ran CloudyG2 LP Rom, installed via aroma, now I'm stuck in fastboot. gg.
Are you sure you're flashing the right versions? i.e. D801 for T-Mobile, etc

Yeah, it was stated on by the pages of which, LS980 (Sprint), VS980(Ver) 802, int.. Etc.
Now I'm having to attempt to modify tot files to change model versions because my phone
Appears to be model LG-F320S in Download mode, but it's not. I flashed CloudyG2 3.0, and his LS980 KK Baseband
And that's what occured me to get stuck in fastboot mode. Now I've been reflashing stock firmware img's and I can't
Get back into fastboot mode, so I'm stuck in Downloading Mode but as I modify the hex, and try to do the tot file, I
Continuously get wrong model number. It's kinda aggravating...
@edit, managed to get back to 4.2.2 stock firmware with this http://forum.xda-developers.com/sprint-g2/general/dll-to-bypass-lg-flash-tool-model-check-t2990665
Now how do I upgrade to Lollipop?
so got d802, rooted, used autorec for twrp, flashed cloudy 3.3 and now have the dreaded black screen,
managed to get into TWRP but pc not recognising phone?
what can i do, i presumed because phone was on kitkat it automatically had a kitkat baseband....
on further reading infact it does not, cant find any of the basebands to flash it,,
managed to get OTG working
any help
cheers

you were on kit kat and flashed a stock based LP rom ? not sure but didnt you have to be on stock LP then flash cloudy.
maybe flash a KDZ theres flasjable ones as zip for LP.
what i done from kitkat is
root/autorec. update twrp 2.8.7.3/bootstacks 5.02. bumped KK. you know you must reboot recovery into recovery again from recovery to take effect. during update of twrp and bootsacks then flash LP KDZ stock. then just wipe and flash cloudy.
Cheers managed to flash cloudy g2.2 over it,
Gps is terrible though
Prerequisites: D802, 32 GB, Stock 4.4.2. I believe "Int" version (original motherboard was replaced)
I tried to upgrade stock 4.4.2 with CM13 and failed with the brick result (LG logo for a couple of seconds and the black screen then).
Now the recovery mode is available (TWRP 3.0.2 bump blastagator) but there is no android image loaded except CM 13.0 snapshot 20160418 which causes the brick state.
The questions are following:
What was wrong?
What proper android image can be used to unbrick?
How to load image on the phone?
Since I found Mount->USB-OTG checkbox in the TWRP, then I hope the OTG cable can be used to load image from USB flash drive. Unfortunately I can check it now.
Will be appreciate for the help.
KK bootloader, that's the reason. If you want to have stock bootstack you need to update to 5.0.2 stock, root and then flash TWRP and CM13. Everything'll work fine.

Thanks edi.
Do I need to replace TWRP bootloader with another one (I guess stock) and then update to 5.0.2 or I can start updating 5.0.2 with TWRP?
If you want to stay with stock bootstack:
You need to flash 5.0.2 KDZ file with download mode.
If you want to do it fast:
You need to flash hybrid bootstack.
Thanks a lot.
Fixed.
