Install LineageOS on voyager
Back to the overviewBasic requirements
- Make sure your computer has
adb
andfastboot
. Setup instructions can be found here. - Enable USB debugging on your device.
Unlocking the bootloader
- On the device, dial
*#*#7378423#*#*
(*#*#SERVICE#*#*
) to launch the service menu. - Go to
service info
>configuration
and checkrooting status
- you can only continue if it saysBootloader unlock allowed: Yes
. - Connect the device to your PC via USB.
- On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
adb reboot bootloader
You can also boot into fastboot mode via a key combination:
- With the device powered off, hold Volume Up and connect the USB cable. The notification light should turn blue.
- Once the device is in fastboot mode, verify your PC finds it by typing:
fastboot devices
Tip: If you seeno permissions fastboot
while on Linux or macOS, try runningfastboot
as root. - Follow the instructions on Sony’s official unlocking website to generate an unlock code for your bootloader.
- Use your code to unlock the bootloader of your device:
fastboot oem unlock <your_unlock_code>
- Since the device resets completely, you will need to re-enable USB debugging to continue.
Temporarily booting a custom recovery using fastboot
-
Download a custom recovery - you can download Lineage Recovery. Simply download the latest recovery file, named something like
lineage-17.1-20210115-recovery-voyager.img
. - Connect your device to your PC via USB.
- On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
adb reboot bootloader
You can also boot into fastboot mode via a key combination:
- With the device powered off, hold Volume Up and connect the USB cable. The notification light should turn blue.
- Once the device is in fastboot mode, verify your PC finds it by typing:
fastboot devices
Tip: If you seeno permissions fastboot
while on Linux or macOS, try runningfastboot
as root.Tip: Some devices have buggy USB support while in bootloader mode, if you seefastboot
hanging with no output when using commands such asfastboot getvar ..
,fastboot boot ...
,fastboot flash ...
you may want to try a different USB port (preferably a USB Type-A 2.0 one) or a USB hub. - Temporarily flash a recovery on your device by typing:
fastboot flash boot <recovery_filename>.img
Note: Newer fastboot releases dropped legacy A/B support, so it might attempt to flash toboot__a
/boot__b
rather thanboot_a
/boot_b
if you try to flashboot
. In this case, you must manually specify which slot to flash to based on what slot fastboot failed to flash to. For example, if fastboot fails to flash toboot__a
, you must flash toboot_a
.Tip: The file may not be named identically to what stands in this command, so adjust accordingly. - With the device powered off, hold Volume Down + Power.
Pre-install instructions
In some cases slot b
can be unpopulated or contain much older firmware than slot a
, leading to various issues including a potential hard-brick. We can ensure none of that will happen by copying the contents of slot a
to slot b
. This step is NOT optional.
To do this, sideload the copy-partitions-20200903_1329.zip
package by doing the following:
-
Download the
copy-partitions-20200903_1329.zip
file from here. -
Sideload the
copy-partitions-20200903_1329.zip
package:- On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
- On the host machine, sideload the package using:
adb sideload copy-partitions-20200903_1329.zip
Note: The copy-partitions script was created by LineageOS developer erfanoabdi and filipepferraz, but isn’t signed with LineageOS’s official key, and therefore when it is sideloaded, Lineage Recovery will present a screen that saysSignature verification failed
