The reality is harsh: every clone owner eventually faces the "2231 brick." While is technically possible—requiring FTDI EEPROM surgery, bootloader flashing, and possibly soldering—it is a time-consuming skill. You must open your plastic HEX-V2 housing to
The main pins connecting the PCB to the metal OBD car plug often crack due to physical stress. Reflow these joints with fresh leaded solder and flux. Fixing Power Failures (No LEDs)
