Threema restore backup on Android 6.0

threema-logoFor english version, see below.

Wird versucht unter Andoid 6 ein manuelles Threema Backup einzuspielen, zB. weil von einer vorherigen Cyanogenmod-Version auf die Version 13 (die aktuell Andoid 6.0.1 enthält) gewechselt wird, ist festzustellen, dass Threema trotz gegebener gewährtem Mediazugiff kein Backup zu finden ist, bzw. immer nur die leeren Ordner Internal Storage/Threema/Backups leer sind.

Zum wieder einspielen eines Backups muss in die Einstellungen der App unter Permissions/Rechte gegangen werden. Dort dann unter den erweiterten Einstellungen (3-Punkte-Button rechts oben) All Permissions/Alle Rechte angezeigt und unter Storage/Speicher alle Leserechte für die SD card gewährt werden. Danach kann jeder Ordner auf dem Internen Speicher angesteuert werden. Nun muss nur noch zum, zuvor hoffentlich erstellten, backup.zip navigiert und es geladen werden.

Sollte das Backup zuvor auf eine externe SD Karte geschrieben worden sein, muss es nur auf den internen Speicher verschoben werden. Ich verwende dafür den Total Comander, dieser benötigt dann die Rechte, um auf die interne Karte schreiben zu können.  Die Ristriktionen unter Android 6.0.1 auf die interne Karte zu schreiben sind deutlich schärfer geworden, darum ist sehr zu empfehlen vor dem Restore noch auf der alten Andoid/CyanogenMod-Version das Backup im Google Backup zu speichern. Dieses kann von Threema dann direkt geladen werden.

To restore your Threema Backup under Android 6 might be a real problem. This is because Threema can not read any folders from internal memory, even if the permission are garanted.

To successfull restore a backup go to settings/apps/threema and enter the permissions, open advanced permissions (3-dot-button), garant read permission to SD card under the storage section. Now you can navigate free on your internal storage and point threema to the backup.zip.

If the backup is stored on the external sd card, just move it to internal sd before. This needs more permissions on the file manager of your choice. I prever Total Commander.

sure shot unbrick Galaxy Ace/5830i and update to CyanogenMod 9

the ultimative way to unbrick it and update the Galaxy Ace 5839i to CyanogenMod 9.1

I know, i am a little bit to late with that topic, because this AndroidOS is more than 4 years old but i spent the last couple of days with that. And so i want to save it for myself.

If your Samsung Galaxy Ace 5830i is bricked (does not start or stuck in a boot loop), here is the ultimative way to unbrick it and update the OS to CyanogenMod9. I use the nightly build from the middle of the year 2015. Because for this phone, never exists a offical release of any other than the original Samsung image.

 

 
Security advice: Never use some of this for an other phone like the 5830i (with the i at the end) especially not with the Galaxy Ace 5830 (without the i)!

Ok let’s start, enjoy your flight and good luck!
