Thank you jaypro, but I have done all that. After the multi-color screen on my Treo, then the Status Bar % appears to always stay in 0% in both sides the Treo and the PC... then the RUU on the PC side throws the error 262. The troubleshoothing part of the guide says it is somehow expected, that the next time the RUU will run without problems, but the Error 262 appears again and again
I will try running RUU in a netbook with XP. Any other idea?
