One step further, thanks to the ICS launcher

Next problem:
When I open "Market" I get to see "You must add an account to the device to continue. Do you want to add one now?"

When I click Yes the "Market"-App closes and nothing else happens...

I was able to "adb push" RootExplorer onto my Fire. Appears in Settings-Applications. But how do I start RootExplorer?

It needs a US Credit Card address.

Hmm, never had that specific thing happen to me. However I did have issues with the Android Market closing on me. I am not by my computer at the moment, but I remember that out of all vending.apk's the one that finally worked for me was the one included in the "gapps.rar" file including all the google apps and is found uner a link posted on these forums under the Kindle Fire Android Market installation tutorial.
Hope that helps...

I was missing the GoogleServiceFramework.apk
Thanks for all the help!

looks like I was (too) optimistic
The app is always closing on me. Tried to install several vending/framework combinations to no avail

Did you install or move the GSF to /system/app?

I just "installed" it

Hi, you need to "just install" the framework (from whichever folder you downloaded it to), then:
- copy the market app
- navigate to /system/apps
- mount the folder as R/W (read/write)
- paste the market app there
- change market's permissions to (rw-r--r--)
- install the market

That should do it

new day...hopefully new luck
Market is up an running, that is, almost running...
Downloads start (at least the progress bar open) but never end . What am I missing?

Try a different market app.
Vending.apk did what you are describing to me. Instead I used com.amarket.apk found in the gapps.zip and worked fine.
