Previously I was able to make dumps and write them to the Macbook Pro 13 Early-2011 and Late-2011 models with similar EFI chips. I've tried different pinouts and AUX Low/HIGH (just in case) and it didn't worked. I use Bus Pirate v3.0a with latest updated Firmware 6.1. In the log it says 5.1 but the same result I've got with the 6.1 Firmware of Bus Pirate.The exact EFI chip model that I was unable to read is MX 25L3205D. Attaching the log file for more info. In other attempts, without specifying chip it gives me just Generic type of chip with 0 voltages. Any info/help would be greatly appreciated.
