tashi,
Thank you for your answer.
Yes. When you asked regarding Zylom I didn't search for more information because I thought it would be easy to erase with the RootAlyzer. But it wasn't.
Regarding Revo, I been using it for many years. But since the Zylom software was uninstalled before, is not possible to use it now.
Anyway. Thanks.
Best regards
Jorge
