Bricked my NSpanel Pro?

I think I may have destroyed my NSPanel Pro while trying to install Homeassistant :X… My device only starts in factory mode where only Chinese characters are displayed. With Google Lens, I was able to translate it and at least restart the EWELink app on the device. However, the device no longer receives a QR code to add it to the app on my phone.
When I try to reset the device with the 5 reboots, as described by Blakadder, it does not start a factory reset but goes to the Android recovery menu where I can navigate with the button on the PCB, but cannot select anything (a power button is needed for this). Does anyone have any ideas?

Hello, please how did you solve it?? i geting now same screen, cannot connect to ADB, so finally its bricked???
