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...
Hello everyone!
Sorry for my bad english
I have the following problem:
I bought on eBay SGH-I317 from USA for use in 2G/3G networks in my country.
Phone finds the networks, but is not registred in them (available only emergency calls).
Later I noticed that the IMEI in the phone information is 0 (*#06# -> 0/02). I think that my operator does not take this IMEI and so it does not register in network the phone.
I tried all the ways how to repair EFS/IMEI, installed the stock firmware via odin, but nothing worked.
The phone has S\N, Wi-fi MAC and other information that is contained in the EFS, only not has the IMEI.
What else can I try to solve this problem?
I would be grateful if someone would send me your EFS backup of I317, so I can figure out which files in a folder EFS is missing in my phone.
I DID IT!
After "dancing with a tambourine" Qualcomm NV Tools has worked, and I was able to hand-write the original IMEI.
Please close this topic.
I accidently completely wiped and bricked the phone when trying to update the recovery through SP Flash Tool.
Now there isn't any IMEI and have tried fixing it with the following but still comes up with invalid IMEI:
SN Writer
IMEI&SN Writer
Chamelephon
Openening Engineering Mode doesn't have any option for CDS to re-write the IMEI.
I have the original two numbers as well.

I managed to write the IMEI with *#6813#
Any idea why calls go straight to message bank when calling this phone?
I am unable to call out from it either.

Hi guyz, Snakeforhire here. For some reason I can't access my old account anymore so had to create another one :/
My 3rd phone (not in production) is a N7100 which behaves weird since I flashed a stock 4.4.2 ROM on it : when I boot it up, it loads OK, recognizes the SIM card and asks for the PIN to unlock it, but once fully booted it doesn't pick up a carrier and displays the barred circle instead Wifi and bluetooth work OK though.
From what I can see it has a valid IMEI (an analyser tool from PlayStore recognizes it as a valid GN2 IMEI), and the EFS doesn't seem corrupted.
"About device" displays the following info :
Android version : 4.4.2
baseband version : N7100XXUFND3
Kernel version : 3.0.31-1280411
(....)
Build #KOT49H.N7100XXUFND3
Any ideas would be greatly appreciated. Thx !
Has the phone been blacklisted from your carrier? Is it possible there is a loose connection inside?
