I read people complaining that certain EFI-enabled Samsung laptops can be accidentally 'bricked' when trying to install an OS or when using certain programs in them, which doesn't happen with BIOS mode. The way I read it, it seems software can cause the hardware to be irreparably
bricked (hard-brick). What does it mean in hardware terms to irreparably damage a laptop due to a software or firmware failure? Is it not possible to re-flash the firmware, even it that means opening it up and using special tools?
EDIT: I understand that even if it takes a lot of effort to unbrick, that would still be considered a "soft brick", not a "hard brick". For example, for routers, sometimes the solution is to open...
... the case, shorting some jumper pins on the board, then connecting the router by the USB cable to an old PC with USB 1.1 hardware, running a special DOS level program supplied by the manufacturer, and powering the router up. This procedure will flash the router to factory settings and original firmware. (http://en.wikipedia.org/wiki/Brick_%28electronics%29#Systems)
