Unfortunately keeping the device in airplane mode is not an option as its main purpose is to show a home assistant status page with onlinescreensaver. Therefore the device updated to 5.15.1.1 yesterday. I now blocked the device in my firewall and only let it access the needed internal server for downloading the png file.

I Think that I now have to reapply the JB from scratch. After factory reset I can short the relevant pins to get it to boot and get it recognized by MFGTool from #60. When hitting start there I can then see the popcorn seemingly beeing applied successfully. After reboot the device is recognized as USB drive and I put the update_jb_hotfix.bin file from Post #73 onto the device. After ejecting and removing the cable the update is not immediately rejected and deleted so I can hit UYK. Unfortunately the update fails with a error and instructs me to restart by pushing the button. I suspect that I have to use the uImage-popcorn-wario file from #72 but this is for wario and my KT3 is a heisenberg.

Is there are new Variant of the uImage for the heisenberg platform that I just missed or can I somehow help on creating one?

Kind regards
Clemens
Hi!

You are indeed correct, the patched hotfix files alone are not enough and you will also need to use a modified payload to replace the keystore first. I only made a wario version as I only own a PW3, but I'm pretty confident I could get it working on heisenberg with little change. Unfortunately, I will only be able to get around to doing this in a couple days, after which I will update this post.
