In the latest Wyze firmware (4.9.4.28) they removed the "/system/bin/singleBoadTest" binary which enabled the SD card interface. I found by trial and error that the SD card interface can be enabled by writing 0 to GPIO43.
When the camera doesn't find run.sh when booting, properly unmount /system/sdcard so that it proceeds with booting the official firmware without the SD card being mounted in two different locations.
This provides a new cfw-1.2.bin firmware rebuilt on the official 4.9.4.28 firmware, so that the SD card with the Xiaomi-Dafang-Hacks firmware_mod can be removed and the camera will boot on the official 4.9.4.28 firmware. This makes Wyze V2 cameras with the jxf23 cmos sensor work again when the SD card is removed (https://forums.wyzecam.com/t/wyze-cam-v2-component-change-transition-to-jx-f23-cmos-sensor/6286). The current cfw-1.1.bin is built on a very old firmware (4.9.1.60) that doesn't support jxf23.

binaries built only by collaborators are accepted due to security concerns. |

Understandable. Do I recreate a pull request that excludes the last commit (d8f5f2b)? |
|
This also works with the latest 4.3.4.37 (I'm running it now). |
|
Is it possible to flash this cfw-1.2.bin using dd instead of the sdcard trick? |
