Backup stalled about open-android-backup

Could you please verify that the cable you are using is working correctly and your phone's charging port is clean? Stalling can happen if you're using a faulty cable. Also try wireless backups and the adb export method.

Hi yes, I can verify my cable is working, charging port clean as the whole process was working for half an hour, phone was untouched during backup.
I tried the adb method and got another error:

Exporting contacts (as vCard) and SMS messages (as CSV).
/storage/emulated/0/open-android-backup-temp/./: 410 files pulled, 0 skipped.
mv: cannot stat './backup-tmp/Contacts/SMS_Messages.csv': No such file or directory

I'm very sorry for not responding to this on time.

It looks like the adb exporting method works well for your device, so use that instead.

The error mv: cannot stat './backup-tmp/Contacts/SMS_Messages.csv': No such file or directory might mean that you're using an outdated version of the companion app - try removing the open-android-backup-companion.apk file in the script's directory.
