first of all, i would like to know what firmware you are using..

as far as i know the best hacking method would be HelloOx
explorer expired, then you should just use the latest version, just waiting 3 seconds on start and quit, aint that much pain if u ask me

to install HelloOx, you need to sign it first, and to get the cert, u can refer to some sites, but due to the warez that is available on that site, i cant share with you here. u can also google various way that u can get ur apps signed so that u can install it. after installation of helloOx, i would recommend you to restart your phone first, then run it. it will handle the rest of the hacking itself. i think at the end of the hacking it will ask u if u want to install an extra app, u can just press no, but i forgot what the app will do XD

after that, ur phone would be hacked, u will see RomPatcher installed, with the open4all patch, which when enabled, will allow you to view private folders.
