LG G3 Cannot connect to network after KDZ Flash

Hi,
After using the KDZ method, my LG G3 cannot connect to the network. I get the "service disabled", "no Service" and sometimes it connects to the operator for some seconds. It is important to say that before the flash, the phone was working fine, and connected normally to the network.
Troubleshoot already done:
1 - Firstly, I flashed using the D85520B_00.Kdz file.
2 - When I realized that the error, I thought this might be a version problem, so I downloaded D85510e_00.kdz version and re-flashed downgrading to 4.4.2. However problem remained.
As a comment, I also noticed that it changed from version D855 to D855V.
What should I do?

Either its a problem with the modem or you lost your efs partition
What does it say under IMEI? Does it still show your phone's IMEI

Yes, it shows the phone IMEI.

Still, that sounds exactly like a corrupted-EFS problem. But with corrupted EFS, in most cases, IMEI is reset to 0... If you have a backup, try to restore it.
If no or if it still doesn't work, try to flash an other KDZ (with modem inside) or just a standalone modem.
Also, check APN and that kind of software things

Hi.
the IMEI SV is set to 00. The IMEI is XXXXXXX... If I go to Network, it will be searching for service. Actually, I can see the network, but I cannot connect to it. I get the message "Unable to Connect to Network". I have already tried 3 kdz versions, without any success.

Just so we're clear your using CSE flash with the kdz right?

Hi did you find the solution...? If yes plz let me know I have the exact same problem...

I have found a lot of threads and people reporting this issue. Bought a D855 32Gb from China that has this problem...
Phone tries to get signal a couple of seconds and then a cross.. and so on..
I tried everything I think, I passed for all the bricks the phone can do: Automatic Reboot / Boot Loop / Fast Boot / Security Error / Factory Reset Status 2 / Dead (QHSUSB_DLOAD) - I can help anyone that has any of those problems : )
In one of the flashes my phone turned to D855RE, similar case to other people, also the message "Current version is not available for user. Can't find matched cust for NT-Code mcc/mnc".
Please if anyone was able to fix the problem report here, there is a lot of people waiting for the answer 20 threads in different networks, I will post the solution in each of those. Thanks!

Hi
I suggest you download the LG phone from app and this will give you which Stock Rom is for your phone. Then you need to search For it and install. I have a D855 Taiwan version and that is what i did and now on Stock D85520W.
Hope this helps.

No service on latest update fok3

I'm running latest ressurection ROM and have this service issues. Sometimes its emergency calls or no sim card. I just replaced the sim tray so it wasn't that. Anyone have an idea how to fix this. Service won't come back on till I reset the phone but only works for 5-15 mins

Does anything think this could be the 4g sensor issue?

Never had any issue here M919/MDL/OK3. Odin the whole ok3 firmware and try again. (Not using ok3 BL myself, still using the old 4.2.2 one, idk if that makes any difference)

Well did you flash with odin or recovery? Stock or custom rom? Did you use the right kernel? Do you have a backup of your IMEI/EFS? Id try to find an official firmware and flash it with odin. Try one of these: http://www.sammobile.com/firmwares/database/SM-A500H/ if you still have problems after flashing stock and dont have a EFS backup...start googling "restore imei galaxy a500h" or something along those lines....good luck and always have a backup of your imei/efs in the future.....also youll prolly get better help if you ask in that devices forum....here: http://forum.xda-developers.com/samsung-a-series/help

I think the problem was I didn't flash the modem after stock. I used the nonhls version which has given me all bars outside my home. Problem solved'

I flash the custom rom

Unknown IMEI and no network

Hey guys,
I need some help.
My LG F180L (i presume cause it said it in the settings but you never know) lost its signal and no the IMEI is unknown.
I didn't do anything with the phone, I bought this phone about 10 days ago and it was working fine then all of a sudden I couldn't hear or send voice over GSM calls (I could talk through whats app or viber) only calls from network wont let me hear or send voice, I could send text message though.
I thought that it might be a software issue and i factory reset the phone, that was it, No signal at all. now it wont find any network at all. Then i just thought of checking the IMEI and IMEI was unknown, all i did was factory reset the phone.
Then i actually thought that stock rom might fix it so i flashed the phone using LG flash tool and installed the KDZ "F180L30e_00".
ofcourse still no signal and the worst case scenario now it drains battery like crazy and wifi is working fine but apps gets stuck a lot.
I have backed up anything, I think if i can find older version of KDZ, then i can flash them may be that might fix the signal issue.
Please suggest me what to.
Thanks.
Regards.

Update : Ok i have flashed F180L20S_00.kdz, now its on 4.1.2 and it seems like the apps are working fine now, over the wifi every thing seems ok, but no signal.
I am not sure what to do, but i have heard flashing the basband might help, i am searching the internet but i cant find the basband, can anyone help ?

IF you are looking for basebands, try here:

Oh sorry, i just didn't saw that you have F180 and i really don't know if you can flash e975 baseband ... so bad.

Thanks guys for getting back at me, i will try the sling baseband first and then probably will flash the international version baseband as well, i already dont have network, i dont have anything to lose
just one question though, if i am using 4.1.2, if i flash 4.4.2 baseband, will it work or baseband has to be exactly the same as the android version ?

i did the result did not change , if i flash custom rom can i fix network eg pixel experience rom ?

How long was it working on Eu rom before it gave you a problem? Maybe you temporarily sim unlocked the phone for 30 days and that ran out?
OnePlus says you must go through tmobile to get it unlocked. Tmobile does need it on their network for a day or so to be able to unlock it. (They tried to do mine manually but there was no data for my phone and there is an exchange that takes place on their server so it has to be online).

Looks like the efs may be somewhat corrupt. Hope you backed up modemst1/modemst2 partitions like the conversion thread suggested you do. You'll want to flash these both back on and then problems should be resolved. You cannot use someone else's partitions, has to be yours.
MSM'ing will not help this situation. Need to unlock permanently using t-mobile's unlock in original ROM after you've restored those partitions. It blows an efuse when it does this, no custom rom can be used as a workaround.

I also had the same problem on OP9. It happened after playing with modemst partition.

unfortunately i tried that too. this problem happened because i deleted modemst1 and modemst2 file in eu rom. I guess the tmo unlock application cannot read the phone's information so the unlock is refusing to bind.
