Unfortunately, I’m not sure how to modify the code to get the job done. Not familiar with file system coding and not the strongest python programmer. Would you mind sharing your modifications? You can PM if you’d like.
Thanks you, IIW, I was able to recover my .product-config. I’m having a little difficulty getting it back on my device. It looks like the root of the sd is mounted at /opt on boot, but maybe it’s not because I can’t copy the file from /opt/configs/.product-config to /configs/.product-config. I tried
chmod 777 /configs/
cp /opt/configs/.product_config /configs/.product_config
sync
and
chmod 777 /configs
cp /opt/wz_mini/tmp/.product_config /configs/.product_config
sync
It should be
chmod 777 /configs/.product_config
Did you try it?
What does ls -la return?
So, /config is empty.

drwxr-xr-x 22 1000 1000 283 Jun 11 2021 ..
I can’t touch to create a file in /configs.
I can’t cp from /opt/.product-config to /configs/.product-config.
/opt/.product config is owned by root and has 777 permissions
Interesting, on my both cameras the failure was different, I had all other config files intact. You might need at least some of them recovered too to successfully boot.
I also noticed that the owner of the configs folder is 1000:1000 on your camera, while on mine it is root:root. Not sure if it is the problem though.
You could also try checking df and mount. On my camera I have this:

You can’t write anything to /configs/ because the jffs2 partition is not mounted. So /configs/ is a normal directory created in “/”, and that filesystem is read only.
You could try to mount it by doing mount -t jffs2 /dev/mtdblock6 /configs and saving the command output to see if there are any errors.
Ok, I think I’ve fixed it with your guidance. After mounting the file system, I was able to confirm all the configs still existed and . product_config was empty. So, I copied the good .product_config over it, and now it blinks red and blue, I’ll have to pair with my wifi as it was originally set up at my dad’s house, but I’m feeling optimistic. Thanks, for helping me turn a paperweight back into a useful tool.

Hope it works for you. Wish I knew someone who could do that to mine. I’m sure you’ll let us know the outcome.
OK, great!
Connected to my account and working 
. Honestly, this should be a service Wyze offers to the people affected by this.
Great news!
Yeah, they could automate this recovery if they wanted to, but they probably figured out that the cost of lost opportunity due to the delaying the release of new products (because the development team would need to spend time creating the fix) is higher than the cost of sending out free cameras here and there.
Do you have a link to the wz_mini_hacks you used? There seem to be several different versions on github etc. None I have found seem to have the “v3_init.sh” file.
I am facing the same issue with v3_init.sh missing
In the version I used it was the wz_init.sh file at
/wz_mini/etc/init.d/wz_init.sh
Yeah, it seems they changed the file structure. I used an older, GitHub - gtxaspec/wz_mini_hacks at f37d3a688027d2142340b62da7dcfc42c8ded73c version.

That would explain why there were no files in /configs/. wz_init.sh is executed too early in the boot process, before the /configs/ partition is mounted.
Yeah, I thought that might be part of it when I saw it wasn’t mounted.
Looks like Wyze FINALLY decided to do something about bricking cams firmwares!!!
