The marking refers to the PCB itself, but the firmware you need depends on the external model number assigned by the manufacturer. The is more than a version string—it defines
If you attempt to flash firmware version 1.1 or 1.0 over 1.2, the bootloader will reject it with error code 0xE7 (Security Violation). This is by design. To downgrade (only for development purposes), you would need a hardware JTAG programmer and a special unlock key from the manufacturer—not available to end users.

A: Yes. Flashing the correct firmware can reset the device to its factory default state, which includes default login credentials. This is a primary use case for this file.
The "Rev 1.2" designates the printed circuit board (PCB) revision. This matters because firmware is tightly coupled with hardware. Flashing firmware meant for Rev 1.1 or Rev 2.0 onto a Rev 1.2 board can permanently brick the device. Hence, is the exact match required.
Depending on how deeply corrupted the operating system is, technicians use three primary avenues to apply the firmware file.
