About this board
This thread is for the IdeaPad 3-17ADA05 with main board NM-C821.

Files listed for this board
- BIOS (full SPI chip dump, .bin)

Usually needed when the laptop powers on with a black screen after a BIOS update, is stuck in a boot loop, or is locked with a BIOS password.
Before flashing, always read and save the original chip. It holds the serial number, UUID, MAC address and ME data for that exact machine.
