Common Issues & Fixes

Phase 2: Firmware & EEPROM Repair

Read EEPROM via CH341A. Look for the serial block at address 0x07F0. If it’s all 0xFF or 0x00, it’s corrupted.
Restore valid data: Use a repair dump matching 22.3.1’s crypto challenge. Paste your original interface serial (printed on the shell).
Flash STM32: Use ST-Link Utility to erase and write the 22.3.1-compatible firmware. Set option bytes to disable readout protection (so you can repair again later).
