S905XQ Tomate - *HELP* How to put this *thing* into bootloader mode so I can flash it using USB Burnning Tool? [Pics included] - Android Stick & Console AMLogic based Computers

Hello XDA community! I need help putting this Tomate S905XQ box in bootloader mode so I can flash it using USB Burning tool.
I tried everything without luck.
What I have done so far:
Plugged the USB cable in the PC, hold the visible RESET then UPDATE buttons but unfortunelly, no dice. (Do I have to plug the ac adapter)
Also tried holding the "hidden inside" UPDATE button but also without any luck.
I want to flash Aidan's Custom ROM v9 on this box (1GB/8GB).
Any help is really appreciated, including how to backup this firmware because I haven't found any version on internet.

Try shorting it , the pins are on the chip just above where it says 905x , have the box attached via usb and have the usb burn tool open , get somehing like sim tray tool and one by one place it in between the pins untill it shorts it will connect ...you may or may not need power plugged in and make sure you use the otg usb slot..
Good luck

Thank you very much for your reply! I'll try that on the weekend.

as mentioned above shorting the pins AKA Mask ROM Mode will be your awnser, look at this thread, look for same type of chip as you have (M logo) even if chip aint the same number mask rom mode will probobly (but not always) be the same, there are 2 chips similar to yours in the thread, so try with those 2 first
