Just pick a different binary or patch AQ with the fix.

Dont know what means pick different binary. Also tried to open the file that i want to flash with winols 8bit search or HxD but on both i dont have any results.Nothing close to the fix in the topic.
And if fix worked, should i do it every time im exporting new file for flash ?

Struggling to get this downloaded and installed right.  Downloaded the fully functional version off the github.  But cant seem to find out how to get it installed.    THe .msi installs the 1.9.4.3 version of the flasher, but still cant see any fast write part of it.

Thats what I normally use when flashing.  Normally takes in region of 4mins 30seconds.

Thought you could get it much quicker than that?

The less you modify the less it will have to write. Also you can try increasing baud rate.

That's about as fast as it will go, since even a single byte change alters quite a few checksums.

Also, because of the way flash works, changing a single byte requires erasing and rewriting an entire flash sector.

It shouldn't take 4 minutes 30.  Single/small changes typically take ~1 minute for me.
