⚠️ Flashing & Safety Notice
Flashing your PCM can be dangerous if not done properly. Follow these steps to avoid bricking your PCM:
- Never flash over Bluetooth or Wi-Fi — always use a hard-wired USB connection
- Connect a battery charger to maintain stable voltage during the write process
- Do not interrupt the process once writing has begun
