Research

The Blackberry PlayBook can't be unlocked through any official methods.

There has been some research into the security of the chipset:

Blackberry implemented a package-on-package configuration for the OMAP4430 and DRAM. JTAG might give more interesting information, some research was done in 2013 by QuackQuack147: https://unlockplaybook.wordpress.com/2013/08/07/progress-irc-chat/ The JTAG pins are probably buried beneath the BGA package.

Porting kexecboot-droid4 might be interesting if there are partitions that are not verified by the bootloader: https://github.com/tmlind/droid4-kexecboot/blob/master/PARTITIONS
