Thingino from Dafang on Wyze Cam v2
I had previously flashed a camera with Dafang and also flashed the boot loader in order to enable 1080 video feeds. When I came to replace Dafang with Thingino I found that the normal install process of putting in an SD card and holding down the button didn't work.
With the help of the developers on Discord I was able to get the camera working again and here is what I had to do. Your mileage may vary.
If you still have a working Dafang camera and associate SD card then make a backup of that SD card. You need to be able to get a shell on to the Dafang in order to complete this process so keeping a copy of the existing card image might allow you to get back to a shell in order to try flashing again.
Ideally find another SD card so that you can leave your working Dafang card alone for now.
You need to be able to get a working shell on to the Dafang install running on the camera.
You need to download:
- The Uniflasher script from Thingino
-
A compiled Busybox with
flashcpenabled. The version that ships with Dafang is missing flashcp. Use the version from wz_mini_hacks. - The correct firmware for your camera. In my case it was thingino-wyze_c2_jxf23.bin
Copy all these files to the root of Dafang SD card (or a clone of it, if you have a spare card).
With those files copied to the SD card, insert the card in to the camera and boot normally in to Dafang.
SSH in to the camera.
First we need to replace the stock busybox with the version from wz_mini_hacks. From the shell:
cd /system/sdcard
chmod u+x busybox
cd bin
cp busybox busybox.ori
cp ../busybox .
rebootOnce the camera has reboot you should be able to go back in to the shell and run busybox. You should see something like:
BusyBox v1.35.0 (2022-05-14 10:38:19 UTC) multi-call binary.
BusyBox is copyrighted by many authors between 1998-2015.
Licensed under GPLv2. See source distribution for detailed
copyright notices.
In the Currently defined functions: section you should see flashcp. If you do, proceed to the next step.
The uniflasher script uses flashcp to write the firmware to the device.
To do that, in a shell:
cd /system/sdcard
chmod u+x uniflasher.sh
./uniflasher.sh thingino-wyze_c2_jxf23.binIf that works you should see:

Done. Please reboot.
Then type reboot
In theory you should now be in Thingino. Using your phone check for a Thingino wifi access point. If you can see one, then connect to it and finish the configuration. You're done!
If not... I had a strange problem which meant that the camera wouldn't boot to a shell. When powering on the camera the LED didn't flash at all. To fix this I downloaded the wyze-cam-2 file from thingino-installers. I formatted the SD card as FAT32 and copied to contents of that wyze-cam-2 zip file to the root of the SD card. Then power off the camera, insert the card, and power on again - but without holding down the button.
If the LED starts flashing then you're very likely good to go. Check for the Thingino wifi access point and you can configure the camera and connect it to your network. Done!
