[LG Optimus 4X HD] skydev:
I have extracted and decompressed bootloader.bin and bootloader.bin.encrypted files. Now trying to get other files.

bootloader.bin (1.1 MB)

https://mega.co.nz/#!PMMmUQpD!R-ii9kNAsAGc7HI03X55YlGtRlIRgrsowPrDqOOoBEI

bootloader.bin.encrypted (1.1 MB)

https://mega.co.nz/#!GR8U2Cxa!KOuWtnoy3FEvN18ScqGAg16lpOgM3am4d06qeDPvHF0

Edit: flash.cfg decompressed (no differences to old flash.cfg one)
