Indoor/Outdoor Batt Cam V2

I bought 2 used refurbished V2 indoor/outdoor battery-operated cameras from Amazon. Both needed updated one did not update. I returned it, got another one. It would not update either. Are there other suggestions different from the two routines that are already available Already in documentation?

Thanks a lot!

If the firmware is available, download and flash the firmware to the cam. I am not sure if Wyze is still actively supporting the v1 or v2 at this time. First check to see if firmware is available to download.
