Unlocking

In android go to SettingsSystemAbout Phone and tap the build number 7 times. Then go to SettingsSystemDeveloper Options and enable OEM unlocking

Reboot to the bootloader and run "fastboot oem unlock" Now select Yes on the phone screen with the volume button and use the power button to accept.

No RPMB

If your device says "SECURE BOOT: ENABLED (NO RPMB)" in the fastboot screen that means that the mainboard in your Nexus 5X is missing an image required by secureboot to function properly. If this is missing then oem-unlocking won't work on the device. It will re-lock every reboot.

No fix is available yet for this.

Special key combos

Boot to bootloader: hold Volume Vown + Power button until the screen turns on.

Launch recovery: first boot to the bootloader, press the Volume Down button twice and press the Power button to select

Install postmarketOS

Go to bootloader then connect the device to the PC then run this commands one by one.

$./pmbootstrap.py init
$./pmbootstrap.py -t 30000 install --no-fde
$./pmbootstrap.py flasher flash_rootfs --partition userdata
$./pmbootstrap.py flasher flash_kernel

Now select start from the menu in the bootloader screen. Reboot again if you don't see anything in the screen after postmarketOS logo

Mainlining

The Linux mainline kernel has very basic support for this phone since November 2016 (one cpu and uart). In January 2017 support for the onboard SDHCI was added and since March 2018 pstore-ramoops. Both should be included in 4.19.

To boot it using pmbootstrap follow the mainlining guide but note that it has a 64 Bit kernel. Also, compared to downstream "device-lg-bullhead" you need to change the debug tty to /dev/ttyMSM0 in the deviceinfo file.

Change deviceinfo (aports/device/device-lg-bullhead/deviceinfo)

 deviceinfo_kernel_cmdline="console=ttyMSM0,115200,n8 androidboot.hardware=bullhead boot_cpus=0-5 lpm_levels.sleep_disabled=1 msm_poweroff.download_mode=0 buildvariant=userdebug PMOS_NO_OUTPUT_REDIRECT"

ttyMSM0 tells the kernel to write debug output to the debugger cable, PMOS_NO_OUTPUT_REDIRECT tells the initramfs script from pmOS to write there as well instead of to a (temporary) log file

Increase the pkgrel in the APKBUILD and rebuild the boot.img

$ pmbootstrap checksum device-lg-bullhead
$ pmbootstrap export

Build your kernel as described in mainlining guide

Update the boot.img to include your local kernel

$ cp "/tmp/postmarketOS-export/boot.img-lg-bullhead" "$TEMP/boot.img"
$ cd .output/arch/arm64/boot/
$ cat Image.gz dts/qcom/msm8992-bullhead-rev-101.dtb > "$TEMP/zImage-dtb"
$ pmbootstrap chroot -- abootimg -u /tmp/mainline/boot.img  -k /tmp/mainline/zImage-dtb
$ pmbootstrap flasher list_devices

You can communicate with the device using screen (or other software), so in a separate terminal start it:

$ screen /dev/ttyUSB0 115200

Boot your mobile to the bootloader (power + vol down) and you should see some debug output on the screen.

Boot the kernel using fastboot

$ pmbootstrap chroot -- fastboot boot /tmp/mainline/boot.img
