Clara BW Tolino Shine 5 with Kobo Mode and KoReader bricked

[CodingMonkey]

Hi,

i tried to setup KoReader on my Tolino Shine 5. I downgraded the firmware to 4.X and installed A NickelMenu and KoReader. Everyhthing worked. But then basically I wanted to achieve that all my books from calibre-web-automated get downloaded directly in KoReader and for that in the settings.device.lua I added a URL to my Library in the [DeveloperSettings] and also added a ssl no verify setting. After that my device is stuck. It reboots indefinitely.

After like 1 Minute 45 seconds it automatically reboots it is currently in the Kobo Menu. When I try and hold the power button to force a factory reset it doesn't work.

Also to connect to my pc doesn't work, since the home screen appears also the pop up to connect to my pc, but a millisecond after that it gets stuck and completely unresponsive.

Now I want to know if my device is completely hopeless or If i can trysomething more.
