So? You have a e3 flasher.

you can't jailbreak an 4.75 ofw like whats wrong with you if you badly want jailbreak a PS3 buy 3.55 off internet google your friend hope this helps :yes:

so you have a cech 2001a on 4.75 OFW. should still be downgradable...as long as you used the proper 4.75 downgrade and patch files.......do you have install package files on the XMB?....if so, then you are downgraded and I would assume that the CFW you are trying to use may be corrupted. As long as you have the install package files on your XMB, I would recomend trying to re download whatever firmware you are trying to install and trying to re-install it. if you dont have install package files on the xmb however, then the system is NOT downgraded and you will need to look at the downgrade process as the culprit. Hope I understood this correctly and am not just talking out my ass.....
