How to flash¶
The main SPI flash cannot be written because the vendor firmware disables BIOSWE and enables BLE/SMM_BWP flags in BIOS_CNTL for their latest BIOSes. An external programmer is required. You must flash standalone, flashing in-circuit doesn’t work. The flash chip is socketed, so it’s easy to remove and reflash.
