This is the Optimus 4x bootloader / bct / flash.cfg dump from kdz
http://cafe.naver.com/androidhacker/487 (in Korean)

kdz file can be extracted with LGExtract.exe
The extracted *.dz file is very similar with the old style dz file.
So I can extract it manually (please see the above link)
the old style dz file format: http://www.frenchcoder.com/dzextract...-tool-lg-ks20/

Im not sure It is worth for Optimus 4x
(I don't have Optimus 4x and I can't test it)
but you can try the following recent nvflash crack~

so now we just need the secret SBK key, which is somewhere in the kdz or in the upgrade modem firmware as well.
otherwise those files are worthless, since you cannot boot without a SBK.
and that is IF you get the sbk extracted and they got the device open and you got the driver in place.

the bootloader do seem to contain "unlock" functionality, and it does also seem to support blob files , so one of the partitions should be able to contain a flashable blob like on prime. but still without unlocking mechanism, those blob's need signing too.

Yes, I managed to extract it. Thanks to the hint above.

For the first, got the flash.cfg and bootloader.bin. Will continue tomorrow.
