Problems with flashing firmware

[blacks]

Hi
Great work in this forum to all the hardworking people

I'm a noob at flashing and installing custom firmwares

My problem is that my minix neo x7 isn't accepting certain custom firmwares meaning they get stuck on the boot loop start up screen each time i flash certain custom firmwares.

The only firmware that work with my x7 are the finless stock pre 010 wich i am currently running,the finless 1.8 and 1.6 none of the other custom firmwares that are on this forum for the minix neo x7 work with my device.

Can someone help me solve this problem please
