Hey Folks,
Finnaly i have a solution for the error problem.
First y cleaned in windows save mode all files related to sony ericcson including a lot of pnf files wich you can find having a Sony Ericsson model number in the file name.
Also all gg*.sys and gg*.inf files and the infcache.1 file
Second y installed the Gordon's Gate Flash driver.
Finally i connected the phone after having the battery take out normally and when asking for the driver point to C:\Program Files\Sony Ericsson\Gordons Gate map and select it and then it installs the right driver.
Hopefully it works for everyone !!!!!
Succes
Ronald
