Ezviz S5 Sport bricked accidentally

[FloppyITA]

I bought a new Ezviz S5 Sport (Ambarella A9SE75) and after updating the firmware it's now bricked on a white screen when I turn it on. Although it works fine with phone app I would use the lcd screen. How can I restore my action cam? I found some videos of similar situations about the Eken H9.
Please help, thank you.

What was the original fw version?

The factory one. I followed the instructions on https://support.ezvizlife.com/downlo...tion-camera/94 that is their original website to update it.
