Realistically even if you had the equipment, those phones are beyond economical repair given the amount of time you would have to invest in fixing them.

Even if you remove key Windows files sometimes Windows can recover its self using the backup copies located in %windir%\winsxs\Backup (and several other places depending on system configuration).

But generally bricking refers to the state of disrepair where something has to be thrown in the bin because it cannot be used in the future. The closest PC equivalents would be either corrupting the BIOS/UEFI or over-heating a component like the graphics card.
