Hello Franz,
the paperclip thing (you call it soft reset) essentially turns your T1 off.
You just can't notice it, because your screen stays the way it was previously.
You might want to read some additional info over at the-ebook.org
Especially this
thread
Hate to write it: You should have done so, before trying to root your device.
This way I returned my T1 several times to FW 1.0.something and reinstalled some later fw. updates, but never 1.0.07.
So JSWolf might be right with his statement regarding 1.0.07.
And, of course you will need a good backup.
By installing one from another device, you will also clone some internals as MAC-address and device-ID, affecting Adobe-registration.
BTW: I remember another resent post here regarding downgrading the fw., that essentially deals with your problem and has something about editing some part of the retrieved image with a hex-editor and flashing it back.
Hope this will give you some start
