Open your flashing software and load the correct firmware/dump file. Select the correct COM port and set the baud rate.
Baud rate: 115200 (or 921600, 1500000) Data bits: 8 Parity: none Stop bits: 1 Flow control: none
The USB-to-TTL adapter (e.g., CH340, CP210x, FTDI) is using an unstable driver, or the voltage levels are mismatched (e.g., using 5V instead of 3.3V).
Watch the console. If timed correctly, the software should intercept the BootROM signal and bypass the "wait for get" loop. Step 5: Isolate Signal Interference (The "Hot" Line Fix)
