Just to quickly answer your question properly. Here is how I did it. There might be other ways, but this one worked quite well for me:

Connect your phone with usb debugging enabled and make sure it's well connected:
adb devices #You should see some number now.

adb shell
make sure you got superuser rights:
su
a # will appear

dd if=/dev/block/mmcblk0p11 of=/sdcard/nvram.img #or whatever you wanna call the backed up .img file.

then exit the shell

then type:

adb pull /sdcard/nvram.img #or whatever you called the backup img

you ll find it in your adb folder then. Make sure you keep it safe ;)

*Important commands are in RED. Maybe I missed something, so if you have problems, just tell me. But that should be pretty much it.

Of course you need adb set up, for this to work. There is a small package in my Noob-HOW-TO and you can also find A LOT of tutorials all over xda about adb.

Hello
I've used this method successfully for my P970.
Do you think this would work on an LG L7?

Because I have not found anything on the forum to sim unlock L7.

Thank you

Wipe Data/factory reset

For the noobs (like me) You've missed a step in the tutorial. You should do a wipe data/ factory reset after the phone reboots or the phone will brick.

I followed the steps , it works great. The only problem is that now phone is charging slowly even in wall socket.

Did you backup your nvram? If not, try a factory reset from settings.

Maybe also check the time it takes to fully charge it. If it is more, than before, it might actually even be a hardware failure. Try to compare it with the time it takes to charge it turned off. I might also see, how long my OB takes for that?

With the phone on , it charges from 20-30% to 100% in ~3-4 hours , before it was max 1 hour and some minutes.
Will try with phone off. Thanks :)
LE: i was thinking the problem comes from the usb switching from hidden menu but i dont really know what it could be , after unlock , under AP CP USB Switching , Current Status is "[null]" ,
i select AP USB , retain, but after the phone reboots it`s still "[null]" . Is this how it should be ?
LE2: i checked NO RETENTION , the phone rebooted and now it charges normally :D , connected to pc it charges slowly but i can`t use it as storage or anything else , just for charging.

    INSTRUCTIONS

    To clear the IMEI use the SmartFlash Tool. You must backup for your photos, and applications because it will erase everythings.

    • Open SmartFlash Tool.
    • Open Windows Enabler as administrador. (Click with left mouse button on the icon to activate)
    • Enable Erase entire CP.
    • Choose the firmware and start the process.

    Firmware for SmartFlash: bin/fls and bin/fls+cwm

    image.jpg


    Once process is complete turn on our terminal and check that it has been cleared by inserting a SIM from another company or if we look defaced IMEI by dialing *#06# ... if yes, WE HAVE OUR PHONE UNLOCKED!

    Now we have to restore the IMEI

    RESTORE IMEI

    Now we proceed to restore IMEI. We need to know the IMEI is having our phone, so you can look at the back of the mobile phone or on the invoice.

    • Connect your phone to your PC via USB. (only necessary that is on)
    • Introducing 3845#*970# on the dialer.
    • Select Port settings -> Select USB CP / In 2.3.4 select AP CP USB -> USB CP
    • Download TUTTY and OPEN.
    • In Protocol select Serial, Port is left as is and click OPEN (review the port because sometimes that is not correct)

    seleccionserial1.jpg


    Now write the following:
    • Type AT (If not accepted, or do not see the characters switch ports)
    • Type at% imei (should show current phone IMEI)
    • Type at% imei = x, x, x, x, x ..., (In each X would have to put the number that corresponded to our true IMEI)

    scaled.php


    Once process is done introduce introduce 3845#*970# on the dialer and changed CP USB -> USB AP and ready.

    Reboot the phone and check the IMEI by dialing *#06#.

    This method has been discovered by some people in htcmania with network problems.
    To fix network problems they do this process with orcusen's help, and someone realized that his phone was unlocked.
    After that, the method was used by many people to unlock the phone succesfully.
