| Actually, the PSP isn't broken when you brick your PSP.
The flash0 on your PSP which carries the firmware (operating system) gets corrupt when you brick your PSP. This may be caused by doing something that's not intended...There is nothing wrong with the hardware of the PSP.
The problem is that you can't access flash0 once it's bricked and update it with a different firmware because you have no access to it. This is why Dark_AleX made recovery mode. So you can access flash0 without actually going into the operating system or firmware.
The modchip allows you to have (2) flash0's on the PSP at once. This is incase one flash0 gets corrupt and bricked, you can take the second flash0 from the modchip and un-corrupt (un-brick) the first flash0 which is bricked by using a different firmware.
