Full brick . internal mémory can be unplug . she isn't braze .
Sorry for my english , i just write this , because i a see the internal mémory can be removed on the sony tablet s ( not xperia ) i think you write STS version ( normaly i have post one jpeg ) . maybe that can help to found a good way to break the full brick / black screen / block in apx mode . jtag méhode or something like that .
maybe it's a verry bad idea , i don't know, i just try to help us .
