I fried SOIC-8 IC (Probably power management) on H96 Max X2 PCB (I-BOX TV) by applying 12V
If anyone (@Thang?) has a board like that, please take a close up of that chip on the back side. I might be able to source it and replace it.

BTW, there is native console available on pretty much all Armbian boards, that lets you see linux messages before they appear on the HDMI port. It helps to understand the bootloader sequence, u-boot sequence and gives you root access.
