Unable to make a backup with Titanium Backup

Hi,

in your case you must edit the platform.xml file as suggested here:

SD Card no writing permission in FP2

you can then use the sd card as a backup location for Titanium Backup.

As for the Titanium Backup apk file itself, you can download it directly through http://www.matrixrewriter.com/android/

Just in case for the future…
