I have a 2020 Macbook Pro A2289 and after many attempts managed to get it into DFU mode, using my older 2017 A1706 Macbook Pro (Running Ventura 13.7.8). However, when attempting 'Restore', it fails at step 4 of 4, showing the following error:

Hello, i have a batch of 10 Macbook Pros A2179 bought from a Costco return wholesaler.


The 10 of them show the exact same behavior;

Hello forum,

I'm still relatively new to the world of electrical repairs.

I have a Macbook here that I can't figure out

I removed the logic board and took a few measurements.

But I can't really figure it out.
