Who knows does a failed write actually affect the write count on the keyboard controller?  It shoud be better to stay on the safe side, if possible; also, we'll see what the author of the forked firmware updater will say on that.

flash_tp_upate  in step 1 (ansi and iso are the same)
flash_tp in step 2 (both the same again)
flash_kb_ansi or flash_kb_iso at the end of step 2

This is exactly what I've already described at least a couple of times. Smile  See my description of the "helper" firmware.

Probably nothing good would happen. Smile  The most weird thing is that the ISO variant is supposed to keep working after the "helper" firmware is flashed to the keyboard controller, while the ANSI variant stops working at that point.  I wonder why?

I've already explored the way for reading the current keyboard firmware into a file, but I'm not sure if reading the current firmware is possible without writing something first, or if everything is going to "explode" that way, rendering the keyboard unusable.  I'll make the required changes to the source code of the updater, but would you be willing to test that out?
