RISK OF PERMANENT DAMAGE: This process involves flashing critical partitions (Bootloader/Kernel). If interrupted or if the wrong file is used, the device can be permanently bricked (referred to as a "paperweight").
WARRANTY VOID: This will void any remaining warranty.
FIRMWARE MATCHING: The E8372h has different hardware sub-versions (e.g., 153, 607, 608). Flashing a firmware meant for a different sub-model (like 607 on a 153) will hard-brick the device. Verify your device model strictly.

Critical: The E8372h operates at 1.8V logic (some revs use 3.3V, check with scope). If using a 5V TTL adapter (e.g., Arduino), you will fry the chip. Use a level shifter or a 1.8V-native TTL (like FTDI Friend 1.8V).

After completion, the modem will reboot normally. The LED should blink (searching for network). Access 192.168.8.1 to complete the setup.
