The guy that had infinite reboot with Lenovo logo probably had the same trouble as me. Volume buttons stopped working along with the sensors. I can't get into fastboot mode and using adb via laptop requires confirmation on the phone which is impossible due to sensors.

Edit: just found a workaround: bought an OTG, connected my mouse, went to the privacy policy and found a link which opened a browser. Opened Google Play and installed Nova Launcher. Thanks to the launcher, I was able to go to settings and hard reset.
Edit2: hard reset doesn't help, can't even enable the developer mode. I'm stuck here and QFIL doesn't help.

If you was able to installe nova launcher you should be able to do adb reboot bootloader and then flash the presist.

I wasn't, there was no usb debugging and my laptop couldn't identify the device.
what do you mean with "there was no usb debugging"? Did you enable it? If not you need to enable the developer menu and in there enable usbdebuging...

There was literally no option to enable the developer menu because there was no build number. I couldn't activate the phone and it was very limited.

On the first boot into 075 you should have access to the diag port.
is this only the first time because I've often already booted 075 because I'm desperate because I'm no longer in the quick setting the phone has closed the bootloader I have a week before a new stock Rome loaded on it as the stock rom bad was translated into German and then unfortunately had to realize that other roms are translated just as bad and now wanted to play a custom rome but could not release the bootloader at the other stock rome

Yes the diag port is only open on the first boot. The bootloader should not lock on its own are you sure it is locked?

Can I throw the phone away because I have often booted 075? Yes, the phone is closed trying to play a Custom Rome on the phone with adb and the phone has not responded.

No, you need to install 075 again then on the first boot you can backup the qcn.
