I recently upgraded to Firmware 5S0J from 5S0D and noticed that the error correction has very poor performance compared to 5S0D. I tried to downgrade but this f**ing windows flasher complained(I think you all know what about.). Anyway, I tried to patch the exe-file so it doesn't complain anymore, and it worked! I found out that you got to change the following offsets via a hex editor(use HexWorkshop or similar):

4F6F: 85 --> 84
4F7C: 85 --> 84

As for now, all the windows firmware updates have the same size, so the offsets to be changed are always the same!
If done, you can flash as usual.

I'm not that technical, but if it works; great job.

Thx man, that could be usefull, too. But using the patched windows one, I can directly downgrade to 5S0D and don't have to downgrade to 5S07 first.
