Veteran's password

An old veteran wants to access save his information from a samsung galaxy tab. The catch is, he had a stroke & cannot remember the password. I thought it possible to mastercode it, but alas this process wipes out everything, setting the device to factory default settings, he won't go for this at all.

Any suggestions and detailed walkthroughs that may work appreciated.


For myself i am currently looking into making a bootable usb. Tips welcome.
