How to Fix / Troubleshooting
Safety first: Firmware recovery usually does not require opening power sections, but follow manufacturer instructions carefully.
- Step 1 – Do not power cycle repeatedly: Excessive power cycling during a failed update can worsen corruption. Leave the unit powered while following recovery steps if instructed.
- Step 2 – Use official update tool: Download the latest approved firmware and update utility from Electrify Home. Follow the exact procedure (USB, app, or web interface) to attempt a recovery update.
- Step 3 – Stable network/power: Ensure Wi‑Fi or wired network is stable and that power will not be interrupted during the update.
- Step 4 – Factory reset after update: Once firmware is successfully reloaded, perform a factory reset and reconfigure the charger.
- Step 5 – Board replacement: If the bootloader or flash memory is damaged and recovery fails, the main control board must be replaced.
