Step-by-Step Solution
Test Multiple Power Sources
Try different USB cables power adapters and USB ports including computer USB ports. Use original Wyze power adapter if available. Some cameras appear dead due to power supply issues not firmware problems.
Attempt Manual Firmware Recovery
With camera unplugged hold setup button then plug in power while continuing to hold button for 30 seconds. Look for any LED activity that indicates recovery mode. Release button and wait 5 minutes for potential recovery.
Try SD Card Firmware Recovery
Download recovery firmware from Wyze support site format SD card as FAT32 and copy firmware file named demo.bin to card root. Insert SD card power on camera and wait 10 minutes for potential recovery.
Document Firmware Update Details
Note exact firmware version camera was updating to and when update failed. Check Wyze app notification history for update error messages. This information helps Wyze support determine recovery options.
Contact Wyze Support for Replacement
If camera remains completely unresponsive contact Wyze support immediately reporting firmware brick issue. Cameras that fail during firmware updates are typically covered under warranty for replacement.
