[Q] HELP - F320S No Recovery - KDZ won't flash - can't Root - G2 Q&A, Help & Troubleshooting

Here's my problem
Received brand new LG G2 F320S Korean variant. Have previously had Sony phones with unlocked bootloaders. Assumed LG would be the same.
Hated stock rom so rooted using ioroot, flashed TWRP and installed G3 port ROM
Inserted SIM card but phone wouldn't detect
Reflashed baseband thinking that would help, no luck.
Decided to revert to stock
Flashed the 4.2.2 KDZ - I was dumb and didn't notice it was 4.2 not 4.4
Still no sim card detected
Flashed 4.4.2 KDZ
Rooted and recovery now.
Still no SIM card detected.
The SIM itself is fine and I've tried another SIM with same problem.
The IMEI is showing up correct. Could I have killed the EFS partition when installing custom ROM? Would that mess with the SIM card detection?
Help please. Much appreciated

[Q] No sim/signal after downgrade

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.

No modem?

Hi, Installed a custom rom but it didn't detect my sim so i flashed a 6.0 EU modem but i forgot to backup... I tried installing other ROMS but no sim on either of them which has worked before. So i flashed the out of the box stock firmware through adb and reset everything but no sim detection on stock either... How do i get my connection back?

SIMcard not detected, what is going on?

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:
