uint8_t calc_csum = calculate_checksum(raw, raw_len - 1); if (calc_csum != p->checksum) log_error("Checksum failed for type-0x96"); return false;
If the device battery is too low (typically under 30-50%), it may fail to sustain the high-speed data connection required for flashing. Recommended Troubleshooting Steps Reinstall Drivers: the data packet with type-0x96- returned was misformatted
