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...

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 have a prolem
I used rom Ditto but something went wrong during an upgrade and so I did downgrade.
First problem

2) I followed all guides to repair imei and now
note 2 have imei 0049 but The network working
What can I do to get original imei?
Now mount Android 4.1.2 xxdlk7
Sorry for my bad english
You didn't properly upgrade and downgrade...or maybe something went wrong during the process..Whenever you install a ROM you should always take a backup of your EFS partition in order to avoid such issues.I am sure the DITTO Rom installer must have generated a backup of the EFS while flashing/installing it ..if that is so you will find that in the internal SD card mostly. Secondly,I don't know about other but i have faced this issue with my Samsung Galaxy S2 ...Sometimes the IMEI is proper in the partition but it shows it to be wrong..and the network connects !....and the imei shows proper on restart / flashing other ROM...
This might help !...
1.Search for the EFS restore image created buy the ROM flasher..into ur Computer system
2.Follow this guide http://forum.xda-developers.com/showthread.php?t=2088809 and check if the IMEI comes proper..if it doesnt then use the EFS backup to restore in that case refer this http://forum.xda-developers.com/showthread.php?t=2255943
after kies upgrade
Serial Number: 00000000000
Imei: 004999010640000
using a tool for recover imei
Serial Number: 00000000000
Imei: 004999010640000
but phone working network working message working ecc
the network might evict you maybe later..or i dont know its wierd needs the attention of some person with more knowledge...
