Or simply connect your phone via usb to your computer and type
adb reboot bootloader in your linux terminal that will bring you to fastboot mode.
Where you can see the DEVICE State which is LOCKED.
to check if everything is setup correctly and that you are ready to go type
fastboot devices in your linux terminal, it will give a result similar to this;
If you can see a different number/lettercode you proceed with the next step, otherwise recheck the steps or ask for assistance.
When in fastboot mode type on your linux terminal either
fastboot flashing unlock or
fastboot oem unlock to unlock the Bootloader, this allows to flash other software then the original stock firmware.
It results with following output on PC
... OKAY [ 0.043s] finished. total time: 0.043s
On your Fairphone navigate to unlock the bootloader with volume buttons and confirm with power button.
Now you will receive a warning upon boot as seen in the image below that also acts as a confirmation that your bootloader is unlocked now.
Your Fairphone 3 smartphone is reset now. Either edo the setup quickly. Since all the settings have been wiped from your smartphone. Once done, you have to re-enable USB debugging from Developer options with steps above then type again
adb reboot bootloaderon your Linux machine, it will reboot your phone to fastboot mode. Another possibility is to shut off the phone and enter fastboot by pressing Volume Down + Power Button at the same time until the phone vibrates shortly.
As in the picture below you can see that your DEVICE STATE changed to unlocked.
On your Linux Machine open the archive with /e/-OS that you download from /e/ Website and extract the files it contains into one folder.
From terminal application on PC, navigate to file path where you have downloaded the /e/-OS image,
for example like
cd /path/to/your/extracted/files/ on some machines a right click in the folder allows to open it directly in a terminal. Execute the following commands to install /e/-OS:
fastboot flash system system.img
It will result in the following output on PC:
target reported max download size of 534773760 bytes sending sparse 'system' 1/4 (522236 KB)... OKAY [ 13.515s] writing 'system' 1/4... OKAY [ 2.371s] sending sparse 'system' 2/4 (522236 KB)... OKAY [ 13.881s] writing 'system' 2/4... OKAY [ 2.366s] sending sparse 'system' 3/4 (522236 KB)... OKAY [ 15.326s] writing 'system' 3/4... OKAY [ 2.351s] sending sparse 'system' 4/4 (218904 KB)... OKAY [ 6.729s] writing 'system' 4/4... OKAY [ 1.009s] finished. total time: 57.549s
the next command is
fastboot flash boot boot.img
the linux terminal output looks like this:
target reported max download size of 534773760 bytes sending 'boot' (65536 KB)... OKAY [ 2.027s] writing 'boot'... OKAY [ 0.314s] finished. total time: 2.342s
The next step is done by this command:
fastboot flash vendor vendor.img
which gives us the following in terminal:
target reported max download size of 534773760 bytes sending 'vendor' (368004 KB)... OKAY [ 10.438s] writing 'vendor'... OKAY [ 1.672s] finished. total time: 12.111s
half of the commands are done, the next one is:
fastboot flash dtbo dtbo.img
which gives us:
target reported max download size of 534773760 bytes sending 'dtbo' (8192 KB)... OKAY [ 0.661s] writing 'dtbo'... OKAY [ 0.054s] finished. total time: 0.714s
and finally the last flashing command,
fastboot flash vbmeta vbmeta.img
which throws this at us.
target reported max download size of 534773760 bytes sending 'vbmeta' (4 KB)... OKAY [ 0.130s] writing 'vbmeta'... OKAY [ 0.021s] finished. total time: 0.150s
5. to finalize the flash while still being in fastboot mode we can now relock the bootloader to get rid of the warning messages during boot.
Therefore we simply type
fastboot oem lock or
fastboot flashing lock.
Which will give us again a warning asking us if we really want to relock the bootloader, this erases everything from the phone. Once that is done the phone will start its new /e/-OS system automatically
Voila! Easy, isn’t it?
