Rooted with Towelroot, and Chainfire for the Superuser last week. Installed TiB, and checked in one of its menus to use the external SD card for automatic backups (I believe).
So, I perform a full backup of all apps and data, but I had been having issues with a bad install of Go Launcher so I decide to do a phone reset (to KK 4.4.2) and restore with a fresh OS.
Upon reboot, the phone automatically Dl'ed all of my Google info and apps, contacts, and everything, all by itself. When the phone rebooted, I was surprised to see that I still had root, but without SU. Did another restore just to be sure and reinstalled Towelroot manually. There must have been an update to it since last week as the SU was automatically installed this time and I had SU without needing to install Chainfire. I reinstalled TiB and attempted to do a TiB restore, but learned that all of my backup info had been stored on the INTERNAL SD card and it was all wiped with the phone restore.
So, I go back into TiB settings and try to redirect the storage location to the EXTERNAL SD card by hitting the back button when looking at the file structure, but when I get to the external card, TiB says it's not writable. Some other phone threads mentioned to use the MNT directory but that didn't work either.
So, after all the above, can anyone either talk me through how to get TiB to store externally, or possibly would you provide a link if you know of a thread that allows it to work with our phones (E980 on AT&T). I've tried a few things mentioned on different threads but none of it seems to work!
