HELP, I erased the flash in my PCM

[Programmer]

We hear horror stories all the time--some of the shops that have the GM reflash equipment for performing upgrades have
inadvertently let voltage drop, or used a battery charger when doing a reflash--and have lost communication part way through
the deal--only fix I've heard of is a new PCM. Hope someone else has better news...

    Please help me!!!
     
    I wrote alot of complex code (with at least 1 bug in it) which successfully erased the flash in my '94 GM PCM, but did not successfully re-program it with new bits.  Therefore, I have a PCM which is dead.  
     
    I realize that I can unsolder the flash, reprogram them, and solder (or socket) them back in the PCM.  
     
    Is there any easier way to get the PCM back to listening to the ALDL????  I can easily open it up.  
     
    What do you experts do when they try to reflash a PCM, and you get a glitch, power failure, or some other error code.  I doubt that you throw it away.  How do you recover the PCM???
     
     
    Any help will be GREATLY appreciated
