Hello all, I’ve searched around a bit, but I can’t find any issue similar to mine. I just got a FP5. It arrived today, I took it out of the box, booted it on and proceeded to go through the e/OS install procedure (I would have got it preinstalled, but I was too slow, and the option was gone when I ordered).
Using Chrome, I’ve followed the steps given during the process /e/OS Installer
Activated developer options
Got the unlock code from Fairphone and turned on OEM unlocking
Activated USB debugging
Set USB default to file transfer
Device detection succeeds, and the installer Downloads e/OS, unpacks and reboots the phone. Phone boots into bootloader mode.
And this is where the issue is, at this stage the installer won’t detect the device is connected, when the device is in bootloader mode. “No compatible devices found”
Checking the versions in settings; The phone is on August 5 2025 android security update, Android version 15.
Good catch, yes, I was on Windows. I checked out the links posted, and it did seem I was getting the driver error (yellow alert in device manager). Some steps to resolve I tried didn’t work for me, and I’m on a weird and hacky version of windows on that machine, can’t use Windows update. So I switched to another machine I have running Linux mint instead. (v21.3)
On the Linux mint machine, I installed Chrome and ran the e/OS web installer again. Once the phone rebooted into bootloader mode, this time the connection window in the browser did show a device: “Android”. I selected it, but then pretty instantly got a connection failure error. Refreshed the page and did the whole download and unpack again (this is a very slow machine), this time it wouldn’t progress to the stage where it reboots the phone. Tried a third time, same behaviour.
I included the thread hashtag eosinstaller so that you might compare with the experience of others. Often we have said better to switch to the “manual” cli install, as Post #2 rather than debug the installer.
OK Just got finished, didn’t see your last post @aibd till now, sorry. But I had the same thought.
I tried the manual method on both machines:
downloaded the android platform tools.zip
ran terminal from the extracted directory
‘adb reboot bootloader’ worked (connected phone boots to bootloader mode)
‘fastboot flashing unlock’ gives an output < waiting for any device > and sits there.
I got this both on Windows (It’s a WIN10 machine) and the other Linux Mint 21.3 machine.
Tried various methods, in the end running the commands with sudo worked. I got the bootloader unlocked, eventually flashed with e/OS and booted back into the phone.
