I have a tablet that I am trying to fastboot flash a custom ROM on. The problem is this tablet has no volume rocker. In order to flash, fastboot requires you to press volume on the device up to confirm the flash. My question to bypass this is in a different post.
Device is very obscure: An
Eewrite (manufactured by Alps) e-pad pro by Wisky (sold by novadealshop) bought from Hong Kong, running Android 7.1.1 with a Type-C adapter, a physical home and power button.
Would it be possible to send the volume up signal using a usb-c splitter/hub and a keyboard that has a volume up button?
I want to ask before I buy the keyboard and thunderbolt-3 hub. I am also worried that many of these hubs might not be recognized by the lowlevel stock recovery environment.
