Dear Butters, yes, I want to try. Please help me. Can you additionally see the firmware from post # 318? This is a modification firmware that was made for the Oregon 750 firmware after replacing the nvram and dumping the dump merged from 650 (there was no dump from 750). And then they successfully flashed it with the original firmware for 750. I bricked my 650 with this firmware. Maybe you can find some answers in it? Thank you.
