That is true for pins or patterns, however, for some reason passwords are not included in this rule.

Ended up unlocking the bootloader through adb and my PC, and in doing so, reset the tablet.

Stupid buggy bootloader not letting me reset. >.>

Note to self; set password on it myself, that I remember, so no-one else can do it.

Cheers anyways guys. Oh and now I've played around with the bootloader, I'm rather tempted to flash a custom rom on it as the tablet is blank at the moment anyway

Nope, totally stock.
