So things were going well... I had rooted my S5 thanks to Geohot, was able to install and run Titanium Backup and see my old backups from my last phone. Then when I tried to backup my S5 I ran into the "insufficient space error". A quick Google searched revealed that I needed to edit my platform.xml file to be able to write to my entire External SD. So I did edit platform.xml, reboot the phone and voila.... I can't access either my internal or my external SD card!
Far as I can tell, I screwed up my permission in platform.xml.
Can someone please send me their original so that I can hopefully get my phone fixed?
If that doesn't work I may just have to reformat and lose all my data since I can't find any other way to fix permission since I can't run most of the programs on my phone (I can, however, use Solid Explorer).
