He had me under the assumption he was flashing my ps3 with it??? when i started questioning him about where is the install package folder and if he could point me in the right direction he said "i dont know i only do the mods dont provide tutorials, it can be seen as circumventing."
Well, lets hope he assumed you had a Cobra dongle and installed that CFW.
Did he install any apps? mmCM maybe?
Try and enter the recovery menu and choose option 6. Install 4.25 to 3.55 downgrader PUP. http://www.mediafire.com/?6d8f6fi0hoiy86j
If that does not install, and gives an error or says No Applicable Data. Then you got robbed.
If that does install, I will give you more links to get you to the latest Rogero.
