Check if T2 required voltages disappear in that moment.
Maybe the board restarts; check at least if PPBUS_G3H is steady.

I bought the BY-T200, got the Bios file from a working Mac of the same model. When I try to restore or revive, it gives the error.00B55BAD-9D4B-4055-8B07-772ED65FB4C9.jpeg

I have exactly the same issue with a A1932 (mbp Air). I have not found a solution yet🤬. If I compare with iPhones with a 4014 error the problem could be a bad NAND. Could it be the same problem? (Reball NANDS?)
