I launch it with cmd with admin rights. I have the android drivers installed on my computer but it doesn’t help in any way.

Ok, Windows it is. In case of Windows 10 you might find some hints here …

FP3 How to solve non-recognized FP3 device in fastboot on a Win10 device (easy [/e/] OS installer)

Dear all, I recently decided to try out the [/e/] OS and started doing it according to instructions found here and on the [/e/] forum. However I got stuck in fastboot mode (phone not recognized by the system). While I had the device manager in fastboot mode I went under device manager and tried updating the drivers with the google driver. Win 10 would not let me update the driver (selected option under Other Devices/Android/right clicked and selected update driver then selected “Browse m…

There’s also this … even if over time it turned out to be more of an ADB/MTP repair than a fastboot repair, but who knows …

Here’s a generic driver and ADB/Fastboot repair …

• Disconnect the phone from the computer.
• In Control Panel - Programs and Features:
  Uninstall the Android SDK (if installed) and everything with “MTP” or “ADB” in its name.
• Reboot Windows.
• In Control Panel - Device Manager:
  Enable View - Show hidden devices, and then uninstall every possible ADB, MTP and smartphone device, hidden or not.
• Reboot Windows.
• Connect the phone again. (Windows should install the necessary drivers then automatically. They can be named after a different device, this doesn’t matter.)
• Download the current Android SDK Platform Tools
• Unzip the ZIP file to e.g. C:\platform-tools (you can unzip it to wherever you like).
• Add the path to where you unzipped the tools to the Windows “PATH” environment variable , so adb and fastboot could be run from everywhere without always having to prefix them with the path.
