yup. now you can start the hacking. install x-plore first. then norton, open norton. options, quarantine list, options, restore all. done and exit norton. now you install rompatcher and apply open4all. if you running symbian belle. copy installserver.exe to C/sys/bin. all done. you can start installing or do some heavy modding.
and you can delete norton and if you wish, you can delete the shared folder in the root of C drive.
all the best.
