Select your SD card as the destination and begin the flashing process. Wait until it successfully completes.

If your KESS V2 5017 ECU programmer shows a "Wake up error," fails to read protocols, or completely locks up, the issue is almost always a corrupted internal SD card. Replacing the physical card and flashing it with a clean, pre-configured software repack image is the most reliable way to revive your device.

Delete the existing Update folder if instructed by your repack readme file.
