Use DroneHacks and downgrade the FW again via a PC. That should restore the drone to previous settings and usability.

Hello. We are sorry for the inconvenience caused. Suppose a “Power system hardware error” warning is displayed in the app. In that case, we recommend that you send the product back for diagnosis as it cannot be troubleshooted remotely. Thank you for your cooperation and understanding.

Consider connecting your Mavic 3 to a PC using DJI Assistant to refresh the firmware. I make it a practice to refresh the firmware following any upgrade. This method has prevented any issues post-upgrade for me. Additionally, firmware upgrades via DJI Assistant software are typically quicker than over-the-air updates using an iPhone or Android, which is a significant advantage.
