Hello.
I would like to know how to boot in to preloader, I tried everything and still no luck, and also I would like to disable the MTK "secure" boot and "secure download". My device: (samsung galaxy a12), has a Mediatek MT6765 chipset.
Thanks.

you can try holding the vol up/down key while connecting the device to pc
to disable secure boot use mtk bypass @ https://www.hovatek.com/forum/thread-37957.html

Tried holding vol up and down still doesn't work. Do I have to force preloader?

you need to find the boot key or combination of keys that trigger "mtk usb port" in device manager, test all hardware buttons asides from power button

code 10 signifies that you installed an unsigned driver, it doesn't stop the device from been detected but if you still want to, you can;
uninstall all mtk, vcom related drivers using usb deview @ https://www.hovatek.com/forum/thread-7660.html
then install the "Auto Mediatek USB VCOM Drivers Signed" @ https://www.hovatek.com/forum/thread-16640.html

I uninstalled old drivers and repleaced them with "Auto Mediatek USB VCOM Drivers Signed". I tride every HW key combo and still can't get the drivers to be trigerd in device manager. Every time I tride to boot in to the preloader device manager wouldn't update and I would automaticly get switched to the charging screen partition.

Could be but I can always force it by dismantling the phone, which I don't want to do.

You would need to join points on the board to achieve this. Yet to find a method without dismantling
