This tool allows you to flash your desired firmware with a better method than provided by Olympus.
You download a firmware, transfer it to your SD-Card and just install it. EASY!.
No it's not. If you follow the tutorial it's almost impossible to fail.
But nothing in life is 100% save.
Yes it is. 100%! There is no hacking going on. I only provide an online-tutorial.
The possibility to flash a firmware file was made all by Olympus and no one prohibits you to use this "feature".
Olympus implemented this feature to allow their support team to flash new firmwares easily.
We just use this 'feature'.
If you think there is one let me know here.
If you have a slow internet connection another person can download the firmware for you.
The official Update Tool is not perfect at all and tends to take up to 1 hour.
I get tons of emails of people with broken cameras because of the official tool. It's more secure this way!
