Completed the following twice with a successfully updated and functional cam running FW 4.36.11.7095. The first round of Flash procedures all failed (NOT a Wyze problem - see below). The second round was fully successful:
- Factory Reset CamV3 without SD Card
- Used a Samsung 32GB SD Card
- Flashed to 4.36.8.32
- Flash successful
- In App Setup successful, fully operational
- Factory Reset CamV3 without SD Card

While all the Flashing just about wore out the Setup button through two test rounds, the first test round did reveal an additional possible failure cause when Flashing Firmware.
it appears that the File Management Utility App I am using has a bug in it that is not extracting the .bin file properly to the Root of the mounted SD Card connected by OTR USB Multi SD reader. It shows a successful transfer with the proper .bin name and file size, however remounting of the same SD Card then results in a null file size.
Solution: Using the native File Management App to my OS, I extracted the same .bin files to the SD Cards and successfully completed all Flash sequences.
My conclusion from this test is that the new Firmware is not the cause of cams bricking nor is it the cause for failures in Firmware Flashes. Rather, the OTA Firmware Download, Delivery, and File Verification process prior to the install of the Firmware is failing, thereby creating an incomplete install and a bricked cam. Flash Failures are more likely to be caused by incorrectly formatted or corrupt SD Cards, the wrong .bin file being extracted or renamed improperly, or the File Extraction Utility not properly transferring the .bin to the SD Card.
