Thanks to AlchemistMusicStudio and Kid Nepro on Korg Forums. The easiest way to update your Korg Kronos.

Here are the steps:

6. Connect the USB storage device containing the update files.
7. Press the OK button, a new message will appear: “Are you sure”? Press the OK button.
8. While the system is being updated (1-2 minutes), do not touch the Kronos switches, and never turn off the power.
9. When the update is complete, a new message will appear: “Kronos system version 1.5.0 update complete. Please restart the system”.

I did these steps and it worked like a charm, however after updating I forgot step 10 and got an error: “SYSTEM STARTUP FAILED – please remove any usb devices and restart” and by removing the USB stick it worked.

I made a video of the update, check it out:
