Problem Description

Your Wyze camera shows Error Code 09 which means a firmware update failed. The camera attempted to download or install a firmware update but the process did not complete successfully. The camera may be stuck in a non-functional state, stuck in a reboot loop, or reverted to its previous firmware version. Error 09 occurs when the WiFi connection drops during the firmware download, the camera loses power during installation, or the firmware file is corrupted during transfer. This error can leave the camera temporarily or permanently non-functional if not addressed properly.

Symptoms

  • Wyze app shows Error Code 09 after a firmware update attempt
  • Camera stuck on solid yellow or purple light after update
  • Camera entered a reboot loop cycling between lights after update
  • Firmware update progress bar stopped partway and timed out
  • Camera was updating then went completely dark and unresponsive
  • App shows a different firmware version than expected after update attempt

Recognize these? Here's what usually causes it.

Common Causes

  • WiFi connection dropped during firmware file download
  • Camera lost power during firmware installation phase
  • Wyze server returned a corrupted firmware file
  • Camera storage or memory insufficient for the update
  • SD card in the camera interfered with the firmware update process
  • Previous firmware was too old and could not update directly to latest

Most fixes happen in the first 3 steps.

Warning

Never unplug a Wyze camera while the status light shows solid purple or yellow during a firmware installation. Interrupting the flash process can permanently brick the camera requiring warranty replacement. Always wait the full 5 minutes even if the light appears to be stuck.

Step-by-Step Solution

1

Power Cycle and Retry OTA Update

Unplug the camera for 15 seconds then plug it back in. Wait for the camera to fully boot indicated by a solid blue light. Open the Wyze app tap the camera then gear icon then Device Info then Firmware Version. If an update is available tap Update. Stay on the same screen during the update and do not close the app or navigate away. The update takes 3 to 5 minutes. Ensure your phone stays on the same WiFi network as the camera during the entire process.

2

Remove SD Card Before Updating

Some firmware updates fail when an SD card is inserted because the camera attempts to write temporary files to the card. Power off the camera. Remove the microSD card. Power on the camera and wait for it to come online. Then retry the firmware update through the app. After the update completes successfully you can reinsert the SD card.

Ensure Strong WiFi Signal

Move the camera temporarily closer to your WiFi router before attempting the firmware update. A firmware download is typically 15 to 30 MB and requires a stable connection throughout. If the WiFi drops even briefly during download the firmware file will be corrupted and error 09 occurs. After successfully updating you can move the camera back to its permanent location.

4

Flash Firmware Manually Via SD Card

If OTA updates keep failing use the manual SD card method. Go to wyze.com/support and download the firmware file for your exact camera model. Rename the downloaded file to demo.bin. Format a microSD card as FAT32 and copy demo.bin to the root of the card. Power off the camera. Insert the SD card. Hold the setup button on the camera while plugging in power. Hold for 3 to 6 seconds then release. The status light will turn solid purple indicating firmware installation. Wait 3 to 5 minutes without interrupting. The camera will reboot when complete.

5

Verify Firmware Version After Update

After the update completes open the Wyze app and go to camera settings then Device Info then Firmware Version. Compare the version number to the latest version listed on the Wyze support website. If the versions match the update was successful. If the camera is still on an old version or shows error 09 again try the SD card flash method with a freshly downloaded firmware file.

Quick Solutions

Retry the firmware update through the Wyze app
Flash firmware manually via SD card if OTA update keeps failing
Power cycle camera then attempt update again
Remove SD card before retrying firmware update
Ensure strong WiFi signal before starting firmware update
Contact Wyze support if manual flash also fails

Still having issues? This is usually the deeper cause below.

If the keypad rejects valid codes, a lockout timer may be running — five failed entries locks most keypads silently for 5–10 minutes.
