Dear Ega

I have similar experience. I cannot find any keys can be prrssed/reseted at P4. Turn off /turn on the power also not works. Finally I just ignore this windows (press ok without doing anything else).

Just a remindar that you need to remove 7.03 or elder firmwware in your directory. Otherwise, though the message shows that the upgrade is success, the firmwar3 is still 7.03.
