I wanted to create a new thread for the MXQ Pro 4K since there are I believe 4 different variations of the motherboard. Ever since 006 i have not been able to boot LE from NAND on my blue v1.0 151021 MXQ using stock firmware (p201), back in the day before Kszaq's LE in order to install OE on this box you needed to install a special custom firmware (p200) then proceed to installing OE. Since i had a copy and nothing to loose, i installed the custom version and then installed 007 using the new install method and I was surprise LE actually booted. I tried reinstalling a bunch of times using stock but always ended with a brick.
I think the main issue is LE needs a p200 bootloader while most MXQ have p201, if anyone has a recent p200 build for the v1 please post it.
Firmware I used: MEGA

NOTE: firmware above seems to be a slimmed cleaned firmware with just bare android.
