U2F: Certificate Error // Missing files!

#1

Hello,

My Flipper Zero arrived today and first of all I did a firmware update via the Companion App.

After the update produced various errors, I completely reset the device and set everything up again. Unfortunately, not all data seems to be restored during a reset.

I was able to solve a problem with subghz by copying the files from here flipperzero-sd-card-examples/subghz/assets at dev · flipperdevices/flipperzero-sd-card-examples · GitHub to the SD card.

Unfortunately, there is no U2F directory on the SD card after the reset. If I copy the files from Github into it, as with subghz, I get a certificate error. If I start U2F without these files, I get a message that files are missing.

Who can help me?

You need to delete the Manifest file on your SD and enter the DFU mode and repair from there via qFlipper

Impressive response time :smiley:

This does the job :wink:

The subghz files were now also available and I didn’t have to copy anything manually.

Tank you very much!
