RPN scientific calculator firmware for $13 calculator kit

[toml_12953]

I was trying to reflash one of my chips and got an error partway through. Now I can't power cycle the calculator to reflash it properly. Is there any hope for the chip? If so, how can I get the flash process to continue? It's not a big deal since $12.00 or so for a whole new kit isn't a big strain on my budget but still if there's a way to save the chip, I'd like to know how.
