i tried to solve my problem for 1 day before i make this thread.i have an unbraded ls ks20 with english rom v10c.i tried to pass a greek rom (v10g vodafone).after flash it and the phone start setup shows me a message "illegal use" so i went back to english rom.since then my phone doesn't conect to the network "no service".everything else works fine .what should i do?did i kill my brand new lg ks20?
i really need help!
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.
I do this to find my 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...
Thanya
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.

Hallo,
I'm new in the forum, i was advised to register here in order to try and find solution to a problem my ks20 has after flashing a rom.
I tried today for the first time to flash a rom in my new ks20(i bought it yesterday used with cooked rom on), i followed this guide http://forum.xda-developers.com/showthread.php?t=369481.
When my phone tried to open, after flashing, this message came up "illegal use unavailable OTP Block".So i flashed another rom in order for the phone to open. With the new rom it opened but it had lost IMEI number and cannot connect with any phone network.
I have made a nv backup with LGMDP but when i try to use LGMDP to restore it i have the same message as before "illegal use unavailable OTP Block" when the phone turns on.
I tried with different roms branded and unbranded. I also tried this http://www.myphone.gr/forum/showthread.php?t=181820&page=360
I dont know what went wrong, nv backup procedure was complete, why do you think that nv backup is not good? I am ready to through the phone away
Maybe you can provide me a solution or another nv backup with my imei ( as i read somewhere in here) if the one i have made is not good.
Thanks , waiting for your help.
LGMDP_EURO that i used to change the rom created two folders: one is called NvBackup and the other folder is named with my imei number, i used both .nv2 files that are included is these folders but every time the result after restoring was the message "illegal use unavailable OTP Block".
I don't know what to do!
Please if anybody has a clue
what rom did you last install?
Was it the branded or unbranded version?
The last rom was Greece Vodafone 10g it is branded.
The problem when i tried to install a cooked rom which i think it awas also branded.
My phone is vodafone branded
did you restore your nv2 in emergency mode?
no i installed a new rom (so that the phone could turn on ok even with wrong imei) and i tried to restore with the phone turned on
shut down your phone, start emercency mode(press : "Send" "Browser" "Power") a green led will shine on your mobile and connect it, and try to restore your back up nv2
how can i do that from emergency mode? i don't have "nv Default" option, also there is no "reset database & contents"
if you have msn send me your email adres in a private message.
Unfortunatelly i dont have msn but i have facebook account.If you have one we can talk from there
sure is the same
I have sent you my account by pm

Did you solve your problem?
If not give rickou26 your imei number and ask him to make you a backup nv2 file.
use the program MTTY because it's only USB or has unlock without backup (like me) and has still bluetooth activated car solve the imei and bd address problem with that (should be works with usb cable also) :
1) get the phone recognized by windows and activate modem serial port interface
bluetooth perifs-> properties -> services -> check the 2 boxs
3) start -> programs -> accesories -> communication -> hyperterminal ->
set a name and modem port (should be found in step 1)
'call' (yellow phone)
4) type "AT" (without quotes) should see "OK"
5) type ATZ (activate echo)
6) AT%IDDE to unlock
7) AT%IMEI=X,X,X,X, ....
(15 chars) replace X by IMEI code or what you want
8) AT%BTAD=X,X,x,x,x,x ...
(12 chars from 0x0 ->0xF) same for bluetooth address, warning : the digits are in little endian (inversed)
9) switch off and on and the bluetooth should work again without asking for BD address
this method has worked for a KU380 only by bluetooth without install third party program to backup or repair and should works for other phones
help this dummy out ...
i met with the similar issue....

Hi,
You must generate a new NV2 with my software and your IMEI code (see the box, invoice etc.).. Then you flash your phone in emergency mode, you do erase EFS and you selectiones the NV2.

Thanks again experts
OOPS!
You were following guides on XDA, and throwing random commands in ADB from the posts under the guides (DON'T DO THIS!) and now your slick new ROG phone 2 doesn't have mobile data, calls, wifi, or bluetooth. You quickly find out that flashing the phone with any firmware old or new, doesn't help you, as this issue is directly linked to your chip in your phone.
I quickly found that I needed a QCN file from someone with a rog 2 phone, however I could not get any help here on XDA except from the user Greatuser123, who did not want to give out his QCN file (understandably), but did send me some notes to try and help with other tools.
With nothing working, and no QCN file, I ordered another ROG 2 and waited for it in the mail. After it got here, I quickly extracted the QCN file, replaced the IMEI's in it, and used QPST to restore my phone.
I am simply writing this guide with the generic QCN file with my info masked out of it, so no one has to go through what I went through.
Common issue
This most commonly happens with ROG 2 Phones from the commands:
DO NOT RUN THESE COMMANDS UNLESS YOU KNOW WHAT YOU ARE DOING!
(spaced command to ensure no one runs this!)
fastboot erase modem st 1
fastboot erase modem st 2
Click to expand...
Click to collapse
On most phones, on a reboot, these partitions would be restored on reboot, but not on most ROG's.
Prerequisites
Rooted Phone
QPST
Qualcomm USB drivers
IMEI Converter
Platform Tools
The Fix
Follow the above root linked video, or find the root thread for your phone here on XDA, and root your phone. This will not work unless you are rooted, although I do not know how you would get into this mess without having your phone rooted already.
Install QPST tools
Install Qualcomm USB drivers
Download the attached zip "good_qcn.zip" and extract the .QCN file anywhere on your machine
Open the .QCN file with any Hex Editor (I used HxD) and search for the Hex-Values: 08 3A 85 99 99 99 99 99 99
NOTE: There will be TWO locations with this value. This is where your IMEI_1 and IMEI_2 will go. Your IMEI_2 goes into the FIRST occurrence, while your IMEI_1 goes in the second.
Download the IMEI Converter app and type in your IMEI_1 and click "Convert", place the converted hex output into a notepad or similar
Do the same for your IMEI_2 and place it in the same location
Now that you have the HEX version of both your IMEI's, paste your IMEI_2 in the FIRST occurrence of the fake IMEI in the QCN file
Paste your IMEI_1 in the last occurrence of the fake IMEI and now save your new .QCN file.
Ensure your device is in USB Debugging Mode.
Download and extract the Platform Tools if you do not have them already.
Plug your phone into your computer using either port
Navigate to your extracted Platform Tools and in a Command Line type "adb devices" to ensure your device is visible.
Run a shell with "adb shell" and elevate your permission with "su"
Now it is time to enable Diag mode by running "setprop sys.usb.config rndis,diag,adb"
At this time, if you installed the Qualcomm Drivers, your device manager should have a port similar to "Qualcomm HS-USB Diag". If not keeping trying to re-enter diag mode and ensure the drivers are correct.
Open up "QPST Configuration" which was installed earlier. You should see your phone listed under "Active Phones". Click "Start Clients" -> "Software Download"
The Port field of the QPST Software Download should list your phone, if not something is wrong.
Click "Restore", and in the xQCN field, click "Browse", change the file type from XQCN to QCN, and select your newly made QCN file
Click "Start", and once the process is done, restart your phone
Conclusion
If all went well, your phone should now have all its bells and whistles again. Sometimes it may require a Factory Reset, and this should always be the practice anyways. If you have mobile data, but only H+ or EDGE, dial *#*#4636#*#* on your phone and ensure LTE is provisioned.
Good luck guys!

This QCN came from a global device, but I imagine this could be used to recover the mobile at least temporary to fully fix the device, no matter the origins.

After a lot of heart ache and even making an EDL cable I could not get cell network back. I"ve sent it into ASUS to get fixed. I have made a few backups and will diff them when I get my device back so hopefully I can see what they have fixed so others don't have to experience this.
