Having an issue on several devices that @balbes150 you might have some insight into.
I have several devices that when i try to install to the eMMC it get this error and then it moves everything to the lost and found folder. I've been able to fix a few by just booting into GParted and deleting the partitions on the drive, reinstalling and it seems to work. But I have a few that refuse to allow any 4.xx kernal version to be installed locally. If i revert back to a 3.14 kernel version, it works fine. Any ideas?
