I have a 5" android tablet (I know, I know, world's smallest tablet) running on an Allwinner A33 chip referred to in device info as "astar_evb-eng" that I got from a Chinese no-name manufacturer. I am running Windows 8 (not 8.1) and have installed and tried every version of the adb driver (i.e. Android ADB Interface, which works fine) and fastboot driver (e.g. Android Bootloader Interface, which hates me), and ADB commands always work, but my computer just refuses to see my device from fastboot when it's in fastboot mode. Nothing comes up with "fastboot devices" and things like "fastboot flashing unlock" just hang, perpetually saying "waiting for device..."
As a side note, "adb reboot fastboot" just restarts into the main OS, so the only way I can stick it into fastboot mode is by holding the volume and power buttons. Additionally, "adb reboot bootloader" works (sort of), but the bootloader on the device screen is just the startup picture and that's it (totally static). The only thing that actually works is "adb reboot recovery", and from the recovery menu I can get it into sideload mode, but that's it.
I am running "fastboot devices" in an administrator command prompt window and it comes back with nothing. I need fastboot to work in order for me to use the manufacturer's suite (called PhoenixSuit 3.1.0) to push a new ROM onto the device, as it is presently crippled. I even tried a driver specifically for Allwinner-based devices and it did nothing. Help!
