Butters,

I am testing this hybrid oregon 550(Korean boot.bin and US fw_all.bin). It looks like running OK so far.

I want to minimize risk of bricking this Oregon again...

What may be problems of using this hybrid oregon 550? I guess I can't have licensed map since I can't provide proper serial number.

There can be problems caused by incompatible firmware. I can't upgrade.

These are the problems caused by a hybrid firmware. Am I missing other problems?
