renameotabin and factory reset on 5.18.0.2

Hi,

i have a brand new Kindle Colorsoft (5.18.0.2) and was following all steps on https://kindlemodding.org/jailbreaking/WinterBreak/. Everything went fine until i tried starting Kual. I assumed that the JB did not work despite seeing the file JAILBREAK in my Library. So I followed the guide to factory reset the device. Unfortunately I previously performed renameotabin and I only latter saw the warning on https://kindlemodding.org/jailbreaki...m-a-reset.html.

So I am stuck in the startup while the Kindle tries to download/update. Nothing helps and I do not find the firmware 5.18.0.2 to download.

Did I really messed up and need to update to a newer version (without having the option to JB)? Or is there another way to bypass the screen?

Thanks a lot!
