Why does this happen? The firmware contains a "Board Support Package" (BSP). The BSP tells the processor which pins control the power, which pins read sensors, and where the storage is located. If the hardware revision changes (e.g., the manufacturer moved the Wi-Fi chip from GPIO pin 4 to GPIO pin 5), the v6.0 firmware will try to talk to the wrong pin. The result is usually a device that will not boot, cannot enter recovery mode, and requires a JTAG hardware programmer to fix.

The jump to version 6.0 is rarely incremental. For hardware running on the P75-338 architecture, this firmware update likely introduced several pivotal changes aimed at modernizing the device.
