I tried to set up an account on my rooted prs-t1 and wrecked it doing so. only later I found a posting about that in the forum.
So I used uboots sd card rescue 1.04 .
The reader did not reboot by itself, but after a reset it started normaly with the stock image.
What I noticed only a while later is, that every time I switch the reader off. It starts again with initialisation. I am asked the country, date and time and the example books are installed again.
It tried the rescue again, just with the same result.
Any ideas what might help?
