Never flashed before - but you need a special file (nv?) that is unique to your phone. If you didn't back that up, yes you killed it ! If you did search XDA for instructions on how to restore it.
You can do this step to find your signal.
1.backup your ks-20 NV file,the file you can backup from firmware.
2.firm ENG rom and chose ERASE ESF.
3.complete the flash,you can go in the system,and find Windag_open.cab install on the device,and open engineer mode.
4.open firmware,only flash nv file,since reset ,you will find the signal.

lol, He loss calibration data from handset!!!! If there is no service after flashing without NV backup, only way to resolve that problem to flash the NVRAM with backup of another handset and correct IMEI and BT address.
To everyone,
If u need .nv2 file, pm me with ur imei no. and email address, i can generate one for you, but the last digit, which is calculated by your phone, would likely to be different and also i can only generate branded .nv2 since i only got branded .nv2 file. It could be work in unbranded phone but just u need to flash a branded rom or hybrid rom to use with it.
thank you raykisi you are the best it works 100%.

LG KS20 Network Problem
I have read it. Again, many thanks, specially to you; everithing from there was very helpfull.
I will give you the IMEI number: 357323-01-137914-1
I have managed to write the IMEI to the phone with QPSt; do i need to do something else?
If i conect back with QPST shows the IMEI (without the last digit)
Unfortunatell i don't have a valid backup for the nv file
Any help will be great
Ths in advance
Hi raykisi,
I still have my .qcn file... but what I'm trying to do is a little bit different: put a KS20 rom on a MS25 mobile (similar mobile that we have here in Brazil).
I tried to recover my network config using my qcn backup but I couldn't...
My phone always shows "No Service".
Tooo bad...
;(
Hope you can help me...

What does ERASE EST do? Why would you think this whole procedure will help find the signal? I asked because my KS20 doesn't find any signal in a lot of places but my wife's KS20 does. I am wondering if there is anything I can try to resolve my problem. Thanks.

My phone after flashing doesn't read sim anymore...i thought that nv ram was dead so i needed a nv backup...So finally i have two kinds of nv back up,LGMDP and QPST from a friend of mine...yes i know about imei and if i take its imei i'll change with imei restore but the problem is that i can restore these backups...i have v20g firmware.when i connect to lgmdp it says nv backup does not exist even if i put the files in lgmdp directory...but when i start a restore with QPST it says to me could not communicate in diag mode...i really hope you developers can help me because i tried everything...thanks
up :crying:
Guys please help...
have I galaxy III SGH T999 and installed the gummy ROM recently. I had been getting 3G /H instead of 4g/LTE so I decided to flush an LTE enabler modem. After I did this I have been unable to get service and my IMEI says unknown. Prior to doing this i had backed up my EFS folder onto my desktop using EFS backup tool. Now I am trying to restore EFS to see if it help. Could some please walk me through how to restore this folder? Thanks in advance.
I downloaded EFS pro but I am unable to connect my device. It keeps saying " Trying to connect to ADB server..." "Device not connect!"
Please help me. I flushed this thing at the airport and now I traveling with no means to communicate
Hello Forumers,
I have a galaxy note 3 N7505 with 4.4.2 kit kat android.
One day i decided to do a reset factory without make a backup, so when i reboot my phone and try to make a call, suddenly show me a message "' No network connection". I searched the phone's file and i saw that the efs file was empty.
Do you know any solution for my problem. I've tried to install again the same rom but the efs file is empty again.
Is there any other method to try in order to make my phone usable again?
Thanks a lot!
If you did not backup your efs (imei), you should contact your warranty service! Since efs block contains your IMEI which registers your phone to your provides network with your cell id! It is just likely MAC adress of a computer on a network! Good luck!
Hi,
Have a strange situation with my device LG G3 D855 32G.
The device keeps on loosing connection to the sim card. In the hidden menu, when I run a basic test I see "Usim - Pass" and then switched to "Fail" back and forth.
I don't get a message that there is no sim card.
This started couple of days ago, my device crashed during Android version update and was bricked (with no download mode).
I followed this thread below after downloading LGD855AT-V10e-EUR-32G.zip (tot file).
[GUIDE][FIX][DISCUSSION] LG G3 Hard Brick Recovery.
I managed to get a download mode only after restoring also Cache, System, Userdata.
Then I used LGUP to install D85530B_Global.kdz (Marshmallow).
Anyway, now the device is installed and working but there is the sim card issue.
During the unbrick process I noticed that the Main Board is D850 while the sticker is D855 (I purchased it from an Amazon seller as new).
Also, the retail box of the device show IMEI and S/N which in a look at the internet doesn't fit but the android menu show me the IMEI on the box.
Does it mean it is refurbished?
Can it be possible to install D850 and Forge the IMEI so it will look like D855?
Can it be that the device is looked after the update and there is a SIM verification issue?
In my differential diagnosis:
1. One of the partitions didn't write well when using the BoardDiag_v2.99a tool and then LGUP.
2. SIM socket issue. which not correlate to the fact that the device is new and SIM appears and disappears constantly, even with out moving the device.
3. There is a conflict of board and android version which cause a sim verification issue.
Your input will be welcome (Technical terms are welcome)
Thank you all in advance.
Insert a 4-ply paper with SIM, for me works!
You have a faulty modem installed on your device which is giving you problems.
Try flashing Modem 21C, everything works perfectly with it for me.
Use lg g3 test point on board and force it to go in qhsusb 9008 mode.
Then use smart boot diag v1.3 and its AP_CHIP folder and select d850 model in that app and select yes and yes and yes.
It will booting. Now flash last d850 rom for your country and remember to use flash tool 2014 and cse mode. And flash the rom twice.
It will be fixed.
