Unable to reinstall FP OS after trying out /e/OS

01001 · May 29, 2021, 1:18pm

After trying out /e/ OS on my new FP3+ I decided that I would go back to FPOS. I have followed the steps but each time it gets stuck with an “error reading sparse file”.

I have tried the last few versions of FP OS available on the main site and through the changelog page. Does anyone have any ideas how I can fix this.

The phone will boot into the bootloader, recovery mode works but doesn’t restore the device to working FP OS.

I would be very grateful for any help/suggestions.

Cheers,

As you get various fastboot errors you might check the fastboot SW you’re using… Where did you get it from and on which OS is it running (Windows? Linux? Version?)?

01001 · June 9, 2021, 1:19pm

Thanks, I got the fastboot as part of the android tools download advised in the installation manual for /e/os. Is there anywhere else to get a copy that I can try? I’m on windows but I’ve got a Ubuntu pc I could try. Cheers

Hello,

tried to follow this guide https://support.fairphone.com/hc/en-us/articles/360048050332-FP3-Install-Fairphone-OS-offline after failed OS change to Install /e/ on a Fairphone FP3/3+ - “FP3”. Unfortunately I get exactly the same error as described here.

Is there a solution?

Thx
Charly

Welcome to the community forum.

Did you run into the same error when installing /e/?
Did you try a different cable and/or a different computer (if available)?

cordex · October 14, 2021, 3:32pm

Thanks for the tip, computer change solved the problem. It must have been the computer because the cable is extra high quality.
Best regards
