I have a bad chip read also on my side using a CH341 programmer. Detected the chip and read successfully and I had altered $sys to FF using HXD. Saved as a new file however the flash failed. I repeated a second time and it failed once again during flash. Third time worked after flashing successfully however after resoldering the QFN to the logic board, the Mac no longer boots. I had used the compare data function on HXD to compare the 3 .BIN files and they are all different. Looking for some help is somebody could provide a healthly .BIN dump file.

After doing a little more digging on the board, all Voltage rails are present apart from a test point marked +12V*

Hi Folks anybody have a schematic for a Lenovo ideacentre 310s? Board model number is FT4STMS

Currently facing a no power issue with the board however under thermal cam, the ethernet chip is heating up. 20V coming in correctly 3.3V & 5V

Any help would be greatly appreciated
