I never tried using fastboot on Windows, so i'm not an expert, but you could try to use a different USB cable and also different USB outlets on your computer. You say your device is reachable over adb? Then you're probably in recovery mode (Power + voulume up), for fastboot (bootloader mode) you need to press power + volume down. It takes a while for the phone to boot into fastboot mode and the FP2 does not tell you when it's ready. In the linux command line, you can just type sudo fastboot devices to list the attached devices if you want to check if the device is reachable, not sure about the process on Windows.

If you have a Linux machine nearby, try using that. If not and you can't resolve your issue, ask at https://forum.fairphone.com/ for Fairphone-specific issues.

Are you trying to install Ubuntu Touch? Then i recommend using MDT (Only available on Linux atm iirc).

Good luck!

yes i tried to install cpt installer and magic device tool to install ubuntu touch.
i installed linux about virtual box, but the program ends at the same point.
Have 3 different usb cable, 3 different usb slots, all the same.
@linux i get nothing after typing fastboot devices same like adb
I started the phone with volume -(down) and power button.
I have only a little lubuntu pc nearby...
strange thing is that the phone doesnt work only at fastbootmode,
its normaly connected at the systemproperties
its a brand new fairphone 2 slim, hope they didnt chance something on softwarebase
thx for respond

Weird, I'm out of ideas. I suggest asking over at https://forum.fairphone.com/ or opening a support ticket here: https://support.fairphone.com/hc/en-us

@Fleb

If you have any spare computer laying around to run Linux, I'd really recommend that. Linux inside of Virtualbox won't work correctly for flashing your phone.

On that computer, try typing dmesg -w before you plug in your phone in Fastboot mode. Let us know what comes up when you do that.

Also, you need to run adb, fastboot, and mdt with sudo.

@UniSuperBox said in Fairphone 2 cant get detected in fastbootmode:

Sudo is key. You need to be root. So try

sudo adb devices

Or if you want General root access:

sudo su

Than after typing your password you can follow up without sudo.

I was having the same problem, but managed to install it today, using a script rather than the installer:

and without using sudo:
