I am compiling the AOSP rom for Nexus 7 flo. After the build is completed, I always end up at this screen "type password to decrypt storage".
The factory images work correctly, and the device works. Also there has never been any password. I could understand that the problem seemed to be with userdata partition, so I flashed everything from the factory images, and then flashed only my own compiled userdata.img. And it works, so I am left clueless as to where the problem could be?
So after some searching/asking around, it seems this problem can occur if partitions overwrite each other (any of the img files is too big, particularly boot.img). But how can I verify this? Any thoughts on this?
