With out knowing more about how you flashed the file I'm not going to say this will 100% work but it's very unlikely either of the PCM's are actually bricked unless you altered something in the boot sector of the bin file.

View or download the picture and you will see there is a pin I've highlighted. With the PCM turned ON ground this pin for .5-1 seconds and IMMEDIATELY attempt to re-flash the PCM. Depending on what tool your using to flash with you may need to click start a split second before you release the pin from ground to get the timing on this right. You may only have a 1- 2 second window where the the PCM will be flash-able but that depends on how bad its damaged.

If the flash chips file is only slightly damaged the PCM will boot and start sending either an OS or calibration recovery mode message and will allow you to reflash until the next time its turned off so there is no requirement here on how precise the timing needs to be. It will be in an unlocked state and allow uploading a flash kernel into the ram.

Now if the main OS is badly damaged or there is corrupted information in the boot block the data bus will only come online for a very short time and you will need to time the ground release so as soon as the flash chip resets you are unlocking the PCM and start the flash kernel upload. The flash kernel needs to be uploaded and brought online before the data bus becomes unresponsive again for this to work. The greater the damage in the boot block the less time you will have to upload the kernel.

Here is a video demonstrating recovery on a dead PCM using LS Droid and what this looks like if you were viewing the data bus.
