It can still be selected in pmbootstrap init by typing in the vendor and codename, but you will have to build the kernel package manually.

Known Issues

  • When accessing the audio device (such as via hwtest), the device freezes. After reboot you may be prompted with a "Collecting Logs" screen with an Amazon logo, indicating some sort of firmware level log collector.
  • CPU1,2,3 continuously enable and disable themselves, with logs such as:
[  378.053320] -(3)[0:swapper/3]CPU3: Booted secondary processor
[  378.053334] -(3)[0:swapper/3][name:cpuinfo&]Detected VIPT I-cache on CPU3

  • Although the kernel can detect plugged in USB keyboard, nor X neither wayland can use the keyboard. evtest works tho. USB drives also mounts correctly..

How to enter flash mode

  • You need to be bootloader unlocked via this method: https://forum.xda-developers.com/hd8-hd10/orig-development/unlock-fire-hd-8-2017-douglas-t3962846.
  • After unlock, the normal fastboot doesn't let us flash in the required partitions? See notes on Amazon Fire HD 10 (amazon-suez).
  • Holding vol down + power gets you into TWRP.
  • Flash with the ADB sideload method.
  • However, the default recovery.zip generated by pmbootstrap flashes into the boot partition, not the boot_x partition which is what is needed for this device. The recovery.zip file has to be manually editted to replace boot with boot_x in chroot/install_options and chroot_bin/pmos_install_functions. Again, see notes on Amazon Fire HD 10 (amazon-suez).


Alternatively, you can flash just the boot_x partition and then flash the rest of the system on an external sdcard:

  • pmbootstrap install --sdcard=/dev/...: This will install the rootfs on a SD card mounted on your computer.
  • fastboot flash boot_x boot.img-amazon-douglas: This will flash the initramfs onto the device.
  • Then remove the sd card from your computer and insert it into the device. Then reboot it.
  • Future updates to the rootfs does not require additional fastboot operations.
