Note This device is still running on armhf, although the processor supports armv7. If you own it, change it and test it that way.

What works

  • Display (framebuffer), 16 bit color depth
  • Touchscreen
  • Keyboard
  • USB networking
  • vibrator
  • Wifi

What doesn't work

  • 32 bit color depth ("red screen" issue)

Progress

What's been done:

  • device-htc-vision builds
  • linux-htc-vision builds (using milaq's kernel)
  • device boots

Cmdrwgls created pull request #810 with his work. This work was later finished by mberndt in pmaports!132.

Installation Notes

Obviously you need an unlocked bootloader; refer to [1] for instructions about that. S-OFF is not needed.

Installing the rootfs using fastboot doesn't work due to size limitations in the bootloader, therefore if you want to install postmarketOS to the internal memory, do an Android Recovery Zip Installation. postmarketOS is picky when it comes to the recovery. It works with CWM 6.0.5.0, see [2]. It does not work with CWM 6.0.4.5 or TWRP 2.6.3.0.

Next steps

  • test more hardware: audio, camera, radio, bluetooth…
  • probably more firmware blobs are needed to get some of these working
