Cam v4 cams won't come up on TinyCam Pro since firmware update to 4.52.9.5332

I’m pretty sure I’m following the flashing instructions exactly as it says and the camera is refusing to load and run the prior version.

Possibly, except for this:

Note: We recommend using a 32 GB microSD card in format FAT32 for firmware flashing.

@StingrayJG

Unless I’m doing something wrong and I don’t know it, the camera is refusing to let go of the current version and load the previous one.

It’s likely the size and format (exFAT is the typical default for your 64 GB card) that’s queering your flash attempts. If you use a proper card (32 GB or smaller and formatted FAT32), then you’ll probably have success, because it seems like you’re following the instructions otherwise.

I’m wondering if I might be “stuck” with not being able to go back, unfortunately.

You’re not. Successful flashes back to v4.52.9.4188 have been reported here:

Firmware Updates - 12/3/2025

i have received my 32GB micro sd cards from amazon and successfully downgraded ALL (17) wyze cam v4 back to 4.52.9.4188 from 4.52.9.5332. All my LIVE camera are now functioning and connecting. what a fun weekend project?!! No. Make sure you disable Automatic Update Firmware on the camera setting OR you’ll have to do this all over again.
