maybe I wasn't clear...
My Kindle was perfectly functional, I just wanted to update. It was 4.0.1
But the 4.0.1 in the links was corrupt, so I flashed 4.0
I used matching partitions (my diags is 4.0.1, main is 4.0)
Now my Kindle is working & functional... it's just the matter of update. So all I did was for nothing (removing screensavers, debricking)
I should say that debricking didn't remove the screensaver hack... so maybe there is something wrong that I did?
I tried dd in fastboot, I tried SSH... nothing is working!
