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.

I have the Tmobile Galaxy Note 2 SGH-T889 ( stock rom and rooted ) My original phone has water damage and not working, I bought a main-board on ebay but the IMEI got blacklisted and I didn't know until I replaced the board.
I want to replace the IMEI from the water damage phone into my repaired phone.
I made a backup the file or NV data using the software " NV-items_reader_writer tool " program
I edit the IMEI number in the line 00550 in the backup that I got from the "NV reader/writer tool"
Than I write back my NV data with the new IMEI number back on the phone using ( EFS/QSP/Nv-items_reader_writer), the program says the writing was successful, but the IMEI doesn't change after I reboot the phone...
Why this is happening ? Is there another secret EFS folder in the phone that keeps writing back the old IMEI into the board..
Is there another safe EFS folder located were the phone keeps geting information to rewrite the old number back in the phone..
Or there is something missing that I don't know ,.. why the "NV-items_reader_writer tool" can not save the new NV data in the phone.
Could you help me, please? The old phone cost me about 600$ and I drooped in the rain water , than I bought a new board that cost me over 100$ .. and now Im stock with a pice of junk .. Please help me...
Best regards,
Cesar

Those are the steps I made during the attempt of fixing the IMEI :
1= Download NV-Items_Reader_Writer_Tool.zip and extract the zip PC
2= Installed SAMSUNG DRIVERS on your computer.
3= Enable USB DEBUGGING on your phone.
4=Dial *#7284# on your phone’s dialer.
5= Select Qualcomm USB Settings and then check RNDIS + DM + MODEM and press OK button. (( Im supposed to check RMNET + DM+ MODEM, but I dont have that option in my model of phone))
6=Now connect your phone to computer using USB cable and then launch NV-items_reader_writer.exe as administrator.
7= Save a backup of the file in my PC and open it with NotePad text editor.
8=Go to the line 00550 and edit the IMEI number and replace with the good number from the water damage phone.
9=Separate your IMEI number into blocks of two digits, leaving the first digit alone. Suppose your phone’s IMEI is35516705558781901, separate it like this: 3 55 16 70 55 58 78 19 01
Now add “A” after the first digit, and reverse the sequence of the two numbers in each block of 2 digits. Add 08 in the beginning of the IMEI. Here is an example: 08 3A 55 61 07 55 85 87 91 10
Having done this, replace the first nine values in the NV block with the converted IMEI.
Click on Write button on the NV-items_reader_writer tool.
When it’s done, Im supposed to disconnect device and reboot it.
My new phone’s IMEI should be there. BUT IS NOT.. It keeps showing the old IMEI number that I dont need.. !!
Please Help Me..
Hi all,
I restored /patched wrong qcn file to my LG G3 D852 that I found online. now my phone doesn't register to network.
its look like network keep resetting. I do have backup of my original file but when I tried to restore gives me error
"Received an invalid command from the phone." please help me to filx this error.
update1:
finally I was able to change IMEI to 0, I replaced following field in 12.4.gold.orj.qcn file
fields
'starting from 1A48 to 1A50' replaced with 00
starting 1AD88 to 1AD90' replaced with 00
now my IMEI is 00, but when I tried to replace above field with my original imei file didn't restore gives same error 'phone return unknown command'
do I need to also update serial # field, does any one know which filed I replace for serial #?
I found above imei filed by converting imei to hex format and searched in qcn file. since I don't know serial # of the phone (12.4.gold.orj.qcn file came from)
Hi there,
Need a help of someone good at working with G4 unlocking. Here is the story of whole problem.
I bought an LG G4 from my local market. At the time of purchase it was rooted but not updated, so I thought to update it. I tried to flash it with Marshmallow kdz available at storage cow with H81520B_00, but may be I flashed my phone with wrong kdz file (as I was not aware of matter at that moment) which was not supported by my phone's model as my phone was H815T (HKG version). The flashing of wrong KDZ file changed the ESN, IMEI & MEID of the phone and replaced them with something that is blacklisted in international phone database. because of this reason now whenever I try connect my phone to the network with the sim installed, it doesnt show any connectivity and displays that service is disabled on the phone.
After this incident, I re-flashed my phone with correct kdz available for H815T model but the problem still persists.
Then in many forums I tried to find the solution to revert back my phone's ESN, IMEI & MEID back to the values printed on the back sticker of my phone pasted under the battery. Somehow I was successful to revert the IMEI of the phone back to original but I am unable to change the ESN and MEID values.
I have tried many ways. I tried to use EFS Explorer of QPST but in that, I found that the NV folder which includes the ESN and MEID values is locked and by applying all my efforts and searching everywhere, I am still unable to unlock this folder.
I tried DFS CDMA Tool, it shows my phone's info properly, but when I try to write the old values to my ESN and MEID areas, it says that the values have been written successfully, but when I try to read the values again to check whether they have really successfully written or not then the tool shows the previous corrupted values again.
I tried EFS Professional & CDMA workshop for the same reason and it too showed the same response as DFS.
I need a help from someone who can guide me that how can I unlock the NV folder of my phone and write the correct values of ESN and MEID of my phone back to it so that it can connect to the cellular network.
Apart from cellular network connectivity, all the functionality of the phone is perfectly fine.
Exactly same problem with my G4, only difference is that it connects to network and disconnects again and again. I am able to make/recieve call and sms when outdoors. Ut randomly drops signals even outdoors
Hello everyone I would like to share with you what I just found out, the xqcn file mi5s if open with notepad ++ contains two imei found through the conversion with converter IMEI can be traced back to the exact point of your IMEI just edit them and write your own, unfortunately I am having problems (4G network is not on the band 20 but never detects 4g networks on other bands and I found out that) I assume the procedure is the same as the mi5 I have not tried but would like to try a xqcn backup via QPST a mi5s which works well 4g and enter my IMEI number someone is willing to cooperate?
