An update to my 1st post:
The "used" MCU came. It came out of a car and "worked" when it was in the car. On his the dismantler's bench it did not come up. He grabbed another one same result.
I told him ship it to me anyway, I will risk it. The car won't take a charge at this point, so I need it fixed asap.
My "friend" came over with his laptop and confirmed again that my eMMC was bad. He took out my MCU, installed the used one. Screen was DEAD.
I said, why don't we swap tegra boards in cause we know mine is bad, and the used MCU might have something else wrong with it.
Nope, still doa.
So at this point dismantler has no more MCU 1's. and I'm stuck paying whatever tesla charges for a refurb. FML
I'm pretty salty over this.
I'm willing to bet MCU2 upgrades will come out within a month knowing my luck.
Anyone know how much they charge for this in the LA area?
