Running slow, with SMC bypass works fine:
It has a NVME SSD Crucial P2 (1TB), tried another NVME adapter too.
- No water indicators tripped
- Sensors using iStat /HW show sensible values, only airport showing 129 degree (which is common) since we don't have ASD for this year board.
I have removed and dumped the EFI/BIOS:
- does cleaning the ME Region make sense?

board came in cleaned up from a previous technician.. after examining the board visually I've seen some work done on the EFI/firmware..
I've taken the chip out and it reads ok on Mac EFI Toolkit, I can read the SN and other information normally..
