So If I select wipe data/factory reset, not all of my internal SD data is removed, When connected to the PC, there remains all sorts of bits/directories that relate to old (unused..) apps and data. I see there is also a format internal sd card data partition, however I assume this is a subset of the factory reset operation? Is there a way to remove ALL the data on the internal SD card, to a completely factory clean state, and only then apply GAOSP updates etc. Though clearly you cant wipe all data, as this would also include the update zips?? Any thoughts?
