[Other] Two Chuangmi 720p Camera bricked after firmware update.

Since the last firmware update, a couple of days ago, both my ChuangMi cameras are bricked.
In the main screen of MiHome they are online, but if I try to access to one of them after a few seconds of "Inizializing 5%" the message "Device is offline" appears. There's no issue in the wifi since every other miHome device is working fine.
They are stuck on fixed  yellow led and all the IR leds on also in daylight.

I tried to reset one of them and the problem is also worse now.
I pressed the reset button for 3 seconds, there was no voice.
I tried to put the QRCode in front of the camera anyway, nothing happened.
Now the one I tried to reset is  stuck on blinking yellow led and all the IR leds on also in daylight.

Someone can help me to unbrick them with a recovery procedure?

FOUND THE SOLUTION

Remove both cameras from mi home app.

Followed the instruction in this thread:
http://en.miui.com/thread-525318-1-1.html

But with the recovery file from this link:
https://github.com/jymbob/chuangmi-720-hack/raw/master/tf_recovery.img

Just format the sd in FAT32, copied the recovery file and then turned on the camera, after a couple of minutes it started to talk in chinese... now you can pair it again with the mi home app.

After that the firmware goes back to something of 2017.... now it is uprading to 3.3.6.. let's se if it's going to be bricked again

Try to not turn off the screen of your phone during the process

Aconteceu a mesma coisa com a minha câmera, usei o link da resposta da Nikka93, porém o link https://github.com/jymbob/chuangmi-720-hack /raw/master/tf_recovery.img não está funcionando, quando mando abrir aparece a resposta page not found.
Peço por favor a Nikka93, eXistenZ78 e Alexy33 que se tiverem ainda o arquivo de firmware que me disponibilizem para que eu possa fazer o download e tentar resolver o problema da minha câmera.

The firmware works great, you only have to follow the instructions to the letter.

I found out that if you're not using the original usb cable that came with the camera, no matter what you do it will always be with the fixed led yellow light. Once you change the cable to the original everything works well.
