Just reporting a problem I encountered with the provided script to install Murena /e/OS on my new FP6 (flash_FP6_factory.sh).
When running, it did not make progress after printing ‘Sending bluetooth_a’ on the terminal.
It turned out that the archive ships a fastboot that was different than the one on my system.
After modifying the script to use /usr/bin/fastboot, installation proceeded succesfully… 
Hello @apdv, Welcome to the /e/ users forum.
you are right, it is version v33.0 when latest is v36.0
other fix should be replacing the fastboot binary in the /IMG-e-3.2-a15-20251022539003-official-FP6/bin-linux-x86 folder.
isn’t it simplier ? (for newbies) than modify the script…
Yes, my suggestion is merely a workaround for who runs into trouble now, not a solution.
I would also prefer it, if the script could look for a system adb / fastboot and use those instead of the included binaries. This is even more interesting when running on non-x86 machines.
It is intented to work standalone
I fully understand that. It could still be that way. Just optionally use the system tools (either on request, or “if they’re there, let’s use them. If not, use the included ones”)
Yes, but that is problematic if the older version fails whereas the installed version succeeds.
