I sympathise, the instructions on the Sxth site are terrible. They could easily have just put up a simple guide but no. Let's leave it all to guesswork in what is a risky process that can leave the car unable to start.

Had a similar experience, in my case I flashed the patch first but it failed at 4% leaving the car unable to start. Wouldn't let me try again either saying already patched despite it having failed.

It was fixed by flashing the original map back over the top. Then it seems the original patch hadn't completely failed, it had unlocked the ecu, it just messed up thr map. Once I had a map that matched the patch all was well. So this is probably your issue now.

You need to get your calibration ID and then first download the patch that matches that ID.

Once patched you then need to flash the ecu with a map. Might want to start off with flashing the original map back and see if the car starts. Then if all good flash the tune.

Also check that all infos in your account are correct. (EK1 serial, VIN…)

If VIN doesnt match your cars VIN than it wont work.

And update your EK1 to the newest firmware.

Most is explained in the new wiki…
