This device is still running on armhf, although the processor supports armv7. If you own it, change it and test it that way. |
WARNING: This device is not recommended for future use with postmarketOS due to its armhf architecture. Alpine Linux (the distribution that postmarketOS extends) pmaports#599 has been considering dropping it. The processor of the device may support the armv7 architecture. If so, you can modify the device package and change the architecture accordingly. |

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
