Wyze Error Code 90 – Firmware Issue!

Popular Posts

Wyze cams are more feature-rich than other smart cameras on the market and cost only a third as much.

They are notorious for making some very frustrating errors. Wyze error code 90 is a common one.

Wyze error code 90: What does it mean and how to fix it

Wyze error code 90 indicates that your camera is offline. First, power cycle the camera to fix it. After unplugging the camera, wait for 15 seconds before plugging it back in. Then, allow the camera to re-initialize. If this fails, you will need to flash new firmware on the SD card.

Power cycle Wyze cam

According to Wyze’s support website error code 90 refers to an issue with internet connectivity and requires that you power cycle your cam.

The process of power cycling is simply to turn off all electronic devices. This usually requires that you disconnect the device from its power source.

This resets the device quickly and is a good choice for troubleshooting.

To power cycle your Wyze cam:

  1. Unplug the camera from its power source. It is okay to unplug the camera from either its power source or on the wall.
  2. Allow the camera to fully discharge for 15 seconds.
  3. Reconnect the camera to the power supply and let it restart.

Verify your internet connection

Wyze recommends that you have your internet connection checked next if power cycling your Wyze camera fails to work.

Make sure your WiFi is connected and working properly.

Quick test: Turn on WiFi and open Google on your smartphone. Make sure you are able to search the internet and use it.

Ensure that your WiFi works and that you are connected to the internet.

Quick test: Turn on WiFi and open Google on your smartphone. Make sure you are able to search the internet and use it.

I recommend that you power cycle your modem/router if you suspect there is something wrong with your internet.

This is done by unplugging your router/modem for 60 seconds, then plugging it back into the outlet. Allow your router to reconnect for several minutes.

When you see the green flashing lights on the modem/router, turn on your Wyze camera.

You should not see Wyze error code 90 anymore. However, there are proven solutions that you can try.

Start over by deleting the camera

Some users found that deleting their camera from Wyze and setting it up again solved error code 90 and problems with their internet connectivity.

It takes only a few seconds and is definitely worth it before you flash a new firmware to your SD card.

  1. Open Wyze and click on the gear icon in the upper right-hand corner.
  2. Next, select Device Settings and then Delete Device (at the bottom).
  3. Click Yes to the pop-up window
  4. The cam LED should blink yellow to indicate that the device has been disconnected.
  5. Next, press and hold for 15-20 seconds the reset button located under your Wyze camera until you hear “Ready To Connect”
  6. In the Wyze app, select New Device > Wyze Cam
  7. Enter your WiFI network password and name
  8. With your Wyze camera, scan the QR code displayed on your phone
  9. Once you have finished setting up your camera, name it in the app.

Flash new firmware on SD card

We took every step to fix error code 90.

However, I suspect that you haven’t found the help you need from the power cycling or deleting cam solutions.

Wyze occasionally releases new firmware for their cameras. Too often, that firmware contains a bug that temporarily disables your camera.

Wyze even admitted to this problem. They have a history of releasing firmware that’s not ready for primetime.

We need to flash your Wyze cam’s SD with an older firmware version. Because the older versions were more reliable, we’re using this version.

Let’s start by briefly describing your SD card. FAT32 has been known to have issues with drives larger than 32GB. You might consider a smaller SD card such as 8GB if you are having problems with the steps below.

Follow these steps to flash your SD card:

  1. The Wyze app can reformat your SD card. (Node: MicroSD must be formatted as FAT32 or FAT32 before you attempt to follow these instructions. If not, it will not/never function.
  2. You can place an SD card on your computer.
  3. Download an older Wyzecam firmware version. All firmware versions are available here. Simply search for your product, then click on the version you wish to download.
  4. You must rename the file after it has been downloaded to “demo.bin”.
  5. Add the demo.bin file onto your SD card
  6. After unplugging your Wyze camera, insert the SD card back into it.
  7. Plug your Wyze cam back in
  8. Hold the reset button down on the cam. This could take several minutes.
  9. You can press the reset button when you hear the words “Ready for connection”.
  10. The cam LED light should blink yellow
  11. In the app, set your camera up again!
