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...

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....
flashed my ks20 to upgrade to win 6.1
lost IMEI, bluetooth ID,...
QPST recognises the fone in 'download mode'...
so what can i do to recover my fone?
hi
hi all, i have just the same problem with ks20. I dont have imei and i do not backup the nv files. My phone is just a pda, no signal. On the back of the phone my imei is 357323-01-085909-3. Please help me, i have email [email protected]
Hi everyone,
I guess many of you are in huge pain with the KU990 new version, that is, the ones that cannot be unlocked using lg3g or mtty methods.
Here I would like to describe everything I tried so far and the current status I am locked in today.
My biggest mistake was to not backup my phone (the famous .nv2 file) at the very beginning ! I strongly advise people who wish to modify their phone somehow to first backup with LGMDP !! Otherwise you may end just like me...
I started with a SFR (VDF FRANCE) locked phone and, as I did not have the SFR sim card at that time, I tried to unlock it with both the lg3g and the mtty methods. Unfortunately the unlocking procedures did not work at all, although I ensure I tried everything. I finally read somewhere that the newest KU990 had a supplementary protection that could not be overcome.
In parallel I was able to manage to change the firmware to OPEN or VDF (EURO) versions ranging from v10a to v10j (using LGMDP). So it seems that there is no big issue there.
However at some point in the process (I guess the unlocking), my IMEI was changed. And my phone started to ask me to "Insert USIM card" or to refer to "Invalid USIM card" depending on if a sim was in or not. I understood that USIM was referring to international sim cards so I tried to reinstall VDF firmwares with VDF .nv2 and VDF Flex backups (still not mine), but this made my phone unusable as it displayed a nice yellow screen and the fact that some wallpaper file could not be found. Still I could solve this problem by I changing back to OPEN firmwares and .nv2.
Now I recovered the original sim card from SFR and was able to obtain the unlock code from their hotline. But as my IMEI has been changed, the unlock code fails now.
Thus I tried to reset or to change my IMEI back to what is written below the battery using either lg3g, mtty, QPST or NVEditor. This also leaded nowhere as even reading the IMEI with lg3g and mtty failed and as QPST and NVEditor revealed that the NV_UE_IMEI_I parameter was protected (NV_READONLY_S). I tried many different things with these tools but it does not seem possible to break the protection.
I guess my only chance now would be to insert my old IMEI into an existing .nv2 file. I have found some "NV2 - QCN TOOLS V1.4" that can do this but only on the KU20.
Does anyone has a tool allowing to insert a new IMEI in a .nv2 ?
OR
Did anyone go through the same difficulties and did finally find a solution ?
any help will be greatly appreciated )
please do not ask me how i did this or that for the moment, if I can solve my problem I will certainly return the favor to all of you later on.
Hello,
Have you tested the tools for the KS20, because the. NV2 is certainly quite similar.
@+
Thank you for your suggestion.
I tried the tool but first it returns a NV2 Status Error when I load any .nv2 file, second the IMEI is forced into 357323-01-XXXXXX whereas both my original and current IMEIs start with 353638-02, and third, although the tool indeed creates the file (I chose "Branded nv2"), the backup fails (LGMDP reports four NV ITEMs with NV_BADPARM_S with no more information) and I end up in Emergency mode.
A KU990 version of the tool might do the trick, if it is possible to specify the full IMEI of course. I can send my current nv2 file(s) if it can help anyone...
hi,
Can you send me by PM your backup NV2, the original IMEI and IMEI on your phone now.

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.
after i updated my international P6 to B-125 firmware i got a weird problem, the phone reads my sim card but no signal at all and its always showing "no service" on the home screen, i dont think its hardware cause when i try to search for networks manually it shows all available networks at my country but refuses to connect to mine (Can't connect to this network at this time) and also i tried 911 and it connected and someone answered, so i dont think its a hardware bug, but what else could it be , any help please with that?
edit: ofcourse i tried the sim in another device and its working just fine

Think about that and you must to try this:
Look at this folder "system/cust" and inside the cust folder you must have one folder with the name of your operator mobile company with the files necessary to works...if don't have it that I said you must to put this folder....but now don't know how explain this because I don't know how make it.

i dont have my operator nor any of my country's in this folder, there are other operators like Orange etc, maybe u can share your source for that!!
any help??
Does your device have an IMEI number?
My P6 was flashed with a wrong ROM by the previois owner and somehow the IMEI erased.. This can cause your issue too. If there's no IMEI, the network operators don't let your phone to connect to the network.
