I received the 4 replacement cameras sent from Wyze albeit, I have the same problem. None of these will update firmware. Soon as I complete installation they switch to mandatory firmware update mode. Update attempts end “Update Failed” continuously" I have tried setup on three different networks. A neighbors network, my Aunt’s and ours here at home. Manual flash Pan V3 does not work. I’m using firmware 4.50.1.3603 or 4.50.2.3762 with a freshly long formatted Wyze 32gb sd. I install and reinstalled these 10’ from the router, have used different power sources, reset our router and followed all Wyze prescribed protocols to a T. I’ve scoured forums for a solution. We have a V3 that works perfectly. We have updated Wyze apps, Apple iPhones and use the 2g network for the cams.
What next?
