Thanks for your reply! Good to hear this is not an intended outcome of the update. Earlier today I pinged the dev also. Just posting to the thread as an fyi to the community and folks searching the error.
Also, agreed beta software should not be used in mission critical production environments. Good thing this is not mission critical. Just difficult to access. And still works well with the wyze app, just not the fire stick on the tv via tiny cam.
Heed the recommendation to use a FAT32-formatted microSD card (32 GB or smaller) if you want to avoid some potential frustration.
Understand that the references to “folder” (like in steps 5 and 10) are incorrect and that you should copy the relevant .binfile to the root directory of your microSD card for this process (and then subsequently delete it following a successful flash).
I wondered if that’s what you meant instead of (non-Pan) Cam v4 when I noticed your post in a different topic. I haven’t yet seen any separately downloadable firmware for Cam Pan v4, though I’d like to, and I have no idea if/when those might be forthcoming. Hopefully @WyzeJasonJ can provide some input at some point.
