The Korg Kronos Restore DVD does not provide an option to 'repair' or 'fix' the system files on your device. Instead, it offers only a 'full format' or 'full install', which may not always be necessary to get your Kronos working again.
To overcome this limitation, I've created a small rescue-repair CD/DVD image to help you resolve most system issues without losing any data. You can use this image to modify or back up any data without leaving a trace on your Kronos, all without the need to physically open the device, thereby preserving your warranty.
Important: Please note that booting from this ISO image will not resolve any hardware issues you may have (for instance, if your Kronos doesn’t power on due to a broken mainboard or a faulty power supply). However, it can help with errors that arise during the boot process, particularly when your Kronos displays an error message shortly after starting. Even if you cannot fully repair your Kronos, you may still be able to back up your files as long as your SSD is functioning properly.
NO WARRANTY - USE IT AT YOUR OWN RISK!
- Burn the provided ISO image to your CD (a CD or mini-CD is sufficient; a DVD is not needed).
- Make sure the Korg Kronos is powered off.
- Connect only the DVD/CD drive and your network dongle via USB.
- Make sure the network cable is connected!
- Disconnect all other external devices.
- Power on the Korg Kronos.
- The Kronos will boot automatically from the CD
- You can connect to it using SSH or FTP over the network.
- The DHCP-assigned IP address will be shown on the Kronos display.
- If DHCP fails, the fallback IP
169.254.9.20(subnet mask255.255.255.0) will be used.
- Connect and perform repairs:
- Use SSH to repair or fix any issues as needed.
- Download your files using SCP or FTP, if necessary.
- Finish up:
- Once done, power off the Korg Kronos and disconnect the DVD/CD drive.
