Say i flash file without check summing or anti launch coding didn't code right. The car then doesn't start obviously, is there a way to still flash over obd2? I've heard to wait like 10 minutes then you can flash?

There may be, but I would plan on bootmode writing if that happens.

Ok, results are in. After waiting 10 minutes I was able to flash over obd2. This is after purposely not correcting checksums and writing two step and knowing code would fail to be coded correctly.

Disconnect your battery and wait for 10 minutes. Mostly it works...
