Fairphone 3 softbricked with Usb drivers problems

[Charles.G]

Hello everyone,

I spent time on the forum but I didn’t find the way to fix my problems…
I’ve just got a FP3 on Android and tried to install e/os/. I followed the instructions of Fairphone and the /e/documentation. My laptop is on windows 7.
Since the beginning i had problems with usb drivers and adb didn’t detect the phone everytime. The usb cable work, brand new, charging and connecting the laptop to the phone, but adb didn’t find it. Bootloader unlocked, developper mode ok, OEM unlocking on, fastboot on. USB debugging on, USB pref on file transfer ok.

I finally suceed every step 'till the fastboot commands, had some error message, it couldn’t find the files .img . ADB no longer recognize the FP3, and same with Fastboot. I’m stucked into the fastboot mode on the FP3, and the Recovery mode ends in “no command”. Did I soft bricked the phone ? The Usb cable is charging.

I’ve tried Universal adb drivers, command adb kill-server and start-server, unistall and re-install adb, with no success.

I have no bill for my phone because i’ve got it from secondhand, so I don’t no if Fairphone will help me…
I’m French, sorry if my english sounds weird…

Thanks for taking the time to read me

Hoping someone could hep me, thanks in advance

Hi Charles,

I think the easiest would be to try the manual installation of the Fairphone OS, see here:https://support.fairphone.com/hc/en-us/articles/360043337512-Install-Fairphone-OS-on-Fairphone-3-using-a-computer

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.

No, this is the stock Android dic:recoverymode (<- see link on how to navigate there).

Hi, and thanks for answering me.

I did exactly what you said and I can run adb and fastboot without prefixing them, but when I put ‘adb devices’ in the command it says ;
‘list of devices attached’ and nothing. Same with ‘fastboot devices’

The fairphone is charging but it does not appear in the computer file. The fairphone is in fastboot mode. In the manager of Windows (other devices), I can see ‘Android’ with a yellow warning panel and even with Google USB driver and Universal Adb driver, nothing . I can connect other smartphones to my pc easily, so, I don’t know… Maybe I can try it with another laptop and another usb-c cable.

If you can, it won’t harm.

Hello everyone, using an other laptop and official fairphone usb cable I managed to install e/os. I’m just a rookie with open OS but we have to start somewhere ^^

Thanks for your advices
