Flashing the rootfs and the kernel to NAND would probably work on the Tmobile US verion of HD2 (it has 1gb of storage space), but it is untested for now.

What works

  • Kernel boots
  • Display and touchscreen works
  • Boots with xfce, other UIs are untested

What does not work

  • Everything else, including ssh and telnet connectivity

Progress

  • Got the kernel to compile, based on maniacx's nougat android kernel
  • The qsd8k-legacy kernel boots correctly : [1]

Next steps

  • Check if other things such as wireless conectivity work

Bootloaders

Because of the age of the HD2, there are serval 3rd party bootloaders available, most commonly used:

  • Haret, Haret is a bootloader (provided as haret.exe) to boot linux or android from WITHIN windows mobile, you start windows mobile, not a great choice for postmarketOS.
  • a(MagLDR), Propitary 3rd party bootloader developed by Cotulla, some folks over at Tytung's android forum, reverse egineered it and created aMagLdr, still propietary (?)
  • cLK, based on littlekernel and download possible with cwm or twrp recovery embedded, seems to be the best option. Littlekernel also provides fastboot wich is handy. Only this bootloader is tested right now.

Installation

MAGLDR would probably also work, but using CLK is easier because of fastboot access.

  • Install the rootfs using an SD Card pmbootstrap install --sdcard=/dev/sd?
  • Insert the SD Card
  • Boot the device into the CLK bootloader
  • Flash the kernel to the boot partition using pmbootstrap flasher flash_kernel (flashing to the additional partitions such as sboot or tboot should work too)
  • Select the first option (or the other boot partion if it was chosen in the previous step) to boot the kernel

Flashing the rootfs and the kernel to NAND would probably work on the Tmobile US verion of HD2 (it has 1gb of storage space), but it is untested for now.
