Hello smu44,
I got a solution (in French) - I succeeded in installing eOS on my FP3. It works!
Please find a traduction in english:
1- download the latest version of eOS here You can use Q or R. R is the most recent and works well.
2- download platform-tools for windows here
3- Extract the file platform-tools zip downloaded, then open the resulting folder
4- Put the file eOS in the folder platform-tools and extract it (eOS) in this same folder.
5- in the folder platform-tools, click on button ‘Shift’ and right click, select “open Powershell window”
6- put your FP3 in fastboot mode and connect it to your PC with a USB-C cable that can transfer data. Then in the Powershell window, type ./adb devices
, your FP3 should be listed (note : my FP3 was not listed but I followed the remaining instructions)
- Then, simply copy-paste the command line below in Powershell, one after the other (Caution, it will erase the data!)
Note, on Windows one need to use ./ at the beginning of each command line
./fastboot -w
./fastboot flash system_a system.img -S 522239K
./fastboot flash boot_a boot.img
./fastboot flash vendor_a vendor.img -S 522239K
./fastboot flash dtbo_a dtbo.img
./fastboot flash vbmeta_a vbmeta.img
./fastboot flash system_b system.img -S 522239K
./fastboot flash boot_b boot.img
./fastboot flash vendor_b vendor.img -S 522239K
./fastboot flash dtbo_b dtbo.img
./fastboot flash vbmeta_b vbmeta.img
./fastboot flashing lock
After the command ./fastboot flashing lock
confirm on your FP3 that you want to lock your bootloader.
The FP3 restart and eOS should be correctly installed
