About

This page documents the status of mainline Linux on the OnePlus 6!

The OnePlus 6 is an incredibly powerful and efficient mobile device, well regarded and (bar the notch) an excellent portable work horse, getting mainline Linux working means not only freedom from proprietary software, and security updates as OnePlus please, but also the ability to boot any mobile or desktop distro.

The phone is currently capable of booting modern Linux with only a few patches, see the kernel here and check the table on the right (or above) for the hardware support checklist.

Notes

  • The battery driver is pretty broken right now and will always show the battery as fully charged, be careful not to leave your phone unplugged running postmarketOS as the battery will drain until it's dead, requiring you to charge it while off for a short period before powering on your phone again (and potentially damaging the battery).

Installing

pmbootstrap init

pick enchilada / fajita device depending on your taste :D

Most UIs work well, phosh is quite good, plasma mobile does seems to be more buggy. For phosh set scale=3 in /usr/share/phosh/phoc.ini under DSI-1 to fix scaling.

Now run the following to build and flash:

pmbootstrap install --split
pmbootstrap export

Reboot back into bootloader mode after each of the following commands, replacing enchilada with fajita where appropriate.

fastboot erase dtbo
fastboot flash vendor /tmp/postmarketOS-export/oneplus-enchilada-boot.img
fastboot flash system /tmp/postmarketOS-export/oneplus-enchilada-root.img
fastboot flash boot /tmp/postmarketOS-export/boot.img-oneplus-sdm845

Reboot and you should see dmesg on your screen :D

If you have flashing or booting issues, try first flashing the latest OxygenOS to the slot you want to install postmarketOS to (ie, flash in TWRP from your other slot). If you still have no luck, try flashing OOS 9 as the bootloader can be more forgiving.

It is possible to dual boot with android by following the guide above and using

fastboot --set-active=[a|b]

to switch to your inactive slot before flashing.

The fastboot implementation on OnePlus 6 is dodgy at the best of times, especially on the OOS 10 bootloader. If you have issues running fastboot commands then choose 'REBOOT BOOTLOADER' from the menu on device and run the fastboot command while it reboots, wait for it to finish. It also helps to reboot back into fastboot after every command.


Issues

Installing

A small number of users have reported their device being stuck on the bootloader unlocked screen after installing, follow the debugging steps below if that happens to you

The first and simplest debugging step is to see if the kernel is booting, this can be done by checking for a gadget mode device appearing in dmesg on your host, you can do this by putting the phone in fastboot mode and then running dmesg -w in a terminal, opening another and running:

fastboot boot /tmp/postmarketOS-export/boot.img-oneplus-sdm845

The terminal running dmesg -w should see output similar to the following:

[79239.786757] usb 1-3: new high-speed USB device number 10 using xhci_hcd
[79240.031271] usb 1-3: New USB device found, idVendor=18d1, idProduct=d00d, bcdDevice= 1.00

[79309.428896] usb 1-3: new high-speed USB device number 11 using xhci_hcd
[79309.684225] usb 1-3: New USB device found, idVendor=0525, idProduct=a4a2, bcdDevice= 5.08
[79309.684227] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[79309.684229] usb 1-3: Product: RNDIS/Ethernet Gadget
[79309.684230] usb 1-3: Manufacturer: Linux 5.8.0-rc6-oneplus-sdm845 with dwc3-gadget

Note the first device up until USB disconnect is the phone appearing in fastboot mode, followed by it booting into the kernel.

If you don't see a USB disconnect line, make sure you have run fastboot erase dtbo. If you do but it is not followed by a new device appearing, try flashing a different version of OxygenOS to the slot you're on (ie by switching slots and then flashing the OTA from TWRP), OOS 9 can behave better. If you still have issues and have tried reflashing multiple times, feel free to contact @kalube in the #mainline:postmarketos matrix channel.

Bluetooth

Bluetooth does not show up in Phosh UI, but works fine with bluetoothctl, not sure why this is.

Sleep

The power button **does** work, but it doesn't turn of the touch screen, as a result your inputs will still be registered with the screen off.

Building

Feel like helping? Want to learn kernel development?

Check out the mainlining guide

For detailed SDM845 specific instructions on initial device porting and building. Feel free to contact @kalube (or anyone) in the #postmarketos-mainline matrix channel if you're stuck.

How to enter flash mode

Unplug from USB, hold Power and Volume Up until you see "Fastboot Mode" text.

Status

Bluetooth

Does work, tested with a bluetooth headset. Requires some messing about with bluetoothctl, doesn't appear in Phosh UI at all, although how much of this is device issues rather than Phosh issues I'm not sure.

sudo service bluetooth start

Then

bluetoothctl
[bluetooth]# power off
[bluetooth]# power on
[bluetooth]# default-agent
[bluetooth]# scan on
[bluetooth]# discoverable on
[bluetooth]# devices
[bluetooth]# pair <device>
-- WAIT --
[bluetooth]# connect <device>
