Could not restore a file due to a failed root command

[x011]

I cannot restore any app, example of the error:

Android 11 - Rooted Samsung S21

Did you try restoring apk alone at first then data alone secondly?

[x011]

I can restore the apk alone, but when I try to restore the data, I get the same error. This error also defeats the purpose of batch restoring backups.

[machiav3lli]

It's already fixed in the v8(still in alphas will take some time to be stable), but it should've worked when you restore data only. Note that this we couldn't identify any direct variable causing this issue specifically on some systems.

Issue still present on 8.2.5 for firefox on android 13 :/

Can confirm. Restoring Mull, which is kind of a fork of Firefox, results in the "failed root command"-error.

Also getting this in 8.36 (Android 9). Maybe half of my apps will restore, and half won't. A typical message:

com.wireguard.android
RestoreAppAction$RestoreFailedException: Could not restore a file due to a failed root command
