Unable to extract backup

[AndersHogqvist]

I try to follow the instructions on how to extract the crypto and devices for Android but with no luck.

adb backup com.plejd.plejdapp

I get a backup.ab that is 4.0K

dd if=backup.ab bs=1 skip=24 | zlib-flate -uncompress | tar -xv

I get the following output:

23+0 records in
23+0 records out
23 bytes copied, 5.1734e-05 s, 445 kB/s

Here I would expect that an apps folder was created but I get nothing.

I have Plejd v5.3.0 on a Samsung Galaxy S21 FE with Android 14 and I'm doing this on WSL2/Ubuntu
