Hello,
on the sd card there are 2 HifyberryOS Partitions in addition to the MBR Partition after the failed update. Is there a way to repair or reset the MBR? I prefer Window-tooling if possible.

I used rp 3 with Beocreate Board. Update by hifiberryOS Webinterface.

Update to hifiberryos-20210531
regards M.Beering

  Ok, to switch to the previous release, edit cmdline.txt

  You should see something like this:

  root=/dev/mmcblk0p2

   

  If it says "2", change it to "3", if it's "3" change it to "2"

  With an Linux -LiveSystem there was no readable content in cmdline.txt. It looks like:

  yyyyyyyyyyyyyy with trema ()

  There were also some .REC-Files looking like dumps in the folder containing not readable characters.

  I delete them and copied a new cmdline.txt from an new hifiberryOS installation.

  The result is now working fine.

  I would like to know more about the file-system und config-files of an hifiberryOS installation. Can you post a Link?
