Notes

  • Device SoC should be similar to SoC in Google Nexus 7 2012 and Google Nexus 7 2012 GSM
  • OTG available - full support, connect and disconnect, at least USB keyboard-mouse and USB drives partially (full USB port, working only when device connected before booting)
  • Battery charges (at least not discharges while OS work). Somehow reports status only in xfce4.
  • Device have 3G modem (not working?)
  • MiniHDMI port available (not working?)
  • I accidentally broke my touchscreen connector on the motherboard, so I'm working with wireless USB keyboard-mouse now

Tested environments

  • lxqt: works fine, can't manage to reboot or power off in UI, doing through terminal
  • xfce4: starts only with startxfce4 in console, weirdly buggy
  • console: works with connected wireless USB keyboard-mouse
  • fbkeyboard: works, can't test touchscreen

Any other UIs is not working, or I can't get them to work for now.

How to enter flash mode

Press Volume Up + Power keys, with Volume Down move selection to Fastboot Protocol, then choose it by pressing Volume Up.

Installation

We can install to sdcard now, so fastboot restrictions is now in the past.

  • pmbootstrap init with vendor wexler and codename qc750
  • pmbootstrap install --sdcard /dev/sda
  • pmbootstrap flasher flash_kernel Partition limit: 8 MB


Legacy information, about flashing directly to the device:

  • pmbootstrap flasher flash_rootfs

It's possible to flash to userdata, but fastboot limit size of images is still to figure out (possibly 800 MB).

  • pmbootstrap flasher flash_rootfs --partition userdata
  • fastboot format system
