== 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 with his work. This work was later finished by mberndt in .
== Installation Notes ==
Obviously you need an unlocked bootloader; refer to 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 . 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
== Partition layout ==
Note that the practical partitions are small. The mmcblk0p25 (system) is 558M, mmcblk0p26 (data) is 1.1G.
For some reason fdisk -l shows overlapping entries. The first 29 partitions seem to be the real ones.
$ fdisk -l /dev/mmcblk0
Omitting partitions after #60. They will be deleted if you save this partition table.
