Yi home camera reset after reboot

Hi all,
I have six YI Home camera with yi-hack-v3 firmware installed, two cameras missed the configuration after reboot.
When I try to paring with the YI home app the camera connected to WIFI without problem but the pairing fail.

The Camera is connected to wifi and I can open the configuration by browser…but after the next reboot the camera start without configuration.

In the cameras, all six camera, there isn’t the sd card in.

Can someone help me?

Thank you.
Kind regards,

Federico
