LG KS20 NVRAM backup

Hi,
I was flashing the handset without backup the NVRAM, and now the phone part is dead. He says "No Service". Can someone help me by sending the NVRAM backup of KS20 in the LGMDP backup format (.nv2) or in NVEditor format. I can restore the original IMEI of my phone.
Thanks in advance!

People already said that it was your fault if you can't use your bricked phone... The instructions to flash say many many many times to BACKUP YOUR NV2 before flashing!!! Couldn't you read that f*****g instructions??? Nobody will solve your problem...and please STOP opening new threads about the same issue!

so, try flash your handset with KS20-00-V10b-CIS-xx-FEB-14-2008 and then try to backup NVRAM. Regards

I've already done a backup of my nv2 file and restored correctly with each ROM I've tried since now. nv2 fiel by other users can't be helpful and , again, nobody can help you if you couldn't read simple steps to flash your phone.

an backup of NVRAM from any LG KS20 handset can help me 100%, be sure. A and you can't backup your NVRAM, if the KS20-00-V10b-CIS-xx-FEB-14-2008 flash presents in your handset 100%, be sure too. The phone is not detected by LGDMP in normal mode(only emergency mode), and nor copiing windiag.dll to windows directory, nor correcting the rgeistry do'nt solve this problem!!!

Are you making fun of me ? Do you know what the nv2 file is for??? Why should I give you my nv2 which contains MY IMEI, MY Bluetooth and Wi-fi addrees, MY brand infos ??? IF there's no service maybe you only need to unlock your phone (see the Thread about it).

You listened about NVEditor? then you can remove any sensitive data. I need only calibration data for radio!

All rom can communicate with LGDMP, with some rom you just need some more steps but nothing very difficult ...

Is there that steps a big secret, or you can tell us about that?

it is 100% our fault that we killed our devices.but we are desperate.and we know that if the guys in this forum have not the answer, there is no answer.

The first step is done.

what do you mean?

did u find a solution?

Can u find any nv2 file? Give me it and i give you solution for your handset.

i don't that file.i have the same problem with you.did you repair the signal?

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.

a big big big big big big big big big big big big big big big thanks to raykisi.my phone after 20 days is back to life again.many many thanks man you are the best.

same problem

When did you unlock with freegee? If its after February you have efs backups in /sdcard/freegee automatically

Since IMEI spoofing is illegal in most country, the IMEI is most likely encrypted. I don't know how it is input on the Optimus G, but I had an issue back with my Galaxy S, and let me tell you, just hope you have a backup!!

where can I found it????? in internet i don't found...

you cant find it. its INTERNAL

JTAG is a tool, made by RIFF, not just a software.Any respectable gsm service has one.Rewriting software with JTAG costs between 10 and 20 euros,depending on the phone.At least here in Romania it costs this much.Don't know other countries.
Bottom line, writing the IMEI it's not a DIY job.it can be done only with proper tools,on a specialised center.
I think there would be another way,but i'm not sure, you need to talk to shelnutt or autoprime to confirm or not.
If the EFS backup from other phone can be decompiled,and the IMEI section is find,change the existing imei on that backup with yours, recompile and restore it with freegeee.i repeat,this is just a theory.
Another question,what method did you use to unlock bootloader?

Even with a samsung, if you'd screwed the partitions real good, you'd lose everything, even the backup.

You can try it, but most likely not.
You would need to decrypt the file, replace with your IMEI and encrypt it. copy it and it "would" work, theorically.
OR, you could call your provider and ask them if they can do it. Might not be worth the hassle!

Yes I can resolve sending the phone in service...But my wife told me "don't to do that""
For me will a victory if I rewrite my Imei because in the future i will change new rom... and want learn how to...
how I can enter in Diag Mode?

you're not sending it for waranty, the "waranty" was void when you changed the rom. If your provider gets to know that they will void it "officialy".
You may contact the service to know if they can rewrite an EMEI, and ask them how much they charge for it.
The FIRST thing you should do before installing a custom rom is a backup of the EFS partition:
http://forum.xda-developers.com/showthread.php?t=2161611
or, if you have installed freeGee, you might already have a backup in the FreeGee folder in img format
If not, then you will need to open thoses .img, edit them with your IMEI and reflash them

Not that easy.i didn't find any tool to decompile those images into workable stuff.like i said,maybe you will find more help on irc channel.asking will not hurt

[Q] LG-E971 weak signal

Hi everyone.
I was flash Korean Rom in my LG-E971. Really stupid - after reading some post . Now whatever I do - flashing stock rom, changing baseband, my E971 signal is very very bad - it drop very often. So is there any thing I could do to fix this problem ? I've read some few post saying that restore your EFS could fix it, but my problem - I didn't make any back up yet . So could any of you could share your E971 EFS back up file ?
Thanks for reading and really sorry for my bad English.
Happy New Lunar year everyone

Please share your E971 EFS . Please please

You do realize that EFS backups are device-specific, not just model-specific, right? Meaning that, if you restore from someone else's backup, you would assume their device's identity, including IMEI number...

Thanks for your info. So I know that impossible to share EFS with others. Is there another way to solved my problem ? . My E971 is now using ly Ipod (

Sorry, I don't know... But let's try and see if your EFS is really screwed up - a good indication of that is usually a lost IMEI (0000... or 0049...). If you dial *#06# on you phone dialer, you should see your actual IMEI - does it show the real one, or "fake"? You can also check it under Settings - About Phone. If your IMEI is intact (it would be nice to check it against the sticker on the box the phone came in, if you have it), chances are good your EFS is OK, and your problem is somewhere else...

It still have IMEI, but signal is very bad. Luckily My friend give me his E975 EFS back up. I've just flash it in my E971, and my problem is now solved. Singal is normal now. There is one thing, that now I have same IMEI with my friend. I hope is not gonna be a big thing cause he is living at other country. Thanks for your reply.Now I could enjoy my device again

Experiencing same problem

No one helped me and i think no one wont help you either i dont have M9 now if i had i'll post a efs backup immediatelly

There is no efs partition on HTC phones. It only exists on Samsung phones.
You probably flashed a GSM RUU on a CDMA device or vice versa. Return to your original firmware and hope that you didn't damage the phone unrecoverably since the partition layout isn't the same on those two variants.

you will mostly need to fix it using OctoPlus Box, efs differ from device to another, so you can't use someone else's efs, OctoPlus Box is a machine not just a software and you will find it with any technician who fixes phones, like in service center, the machine is pretty expensive so i don't think that buying it is a good idea.

thanxx .. i sent my mobile to my friend have a z3x box and he fixed it ..
