hello everyone! i am new to this forums, so firstly i would like to thanx all in advance! i am very new to this downgrading thing and i think i got it all down but i would like to make sure before i go ahead and mess things up... ok.. i have a 2.6 Firmware on my psp, and i think its not a TA-082 because there is cooper lettering but its on the left hand side.. (if your facing the UMD door). i cant tell wat it says, but if im correct the TA-082 is on the right.. soo what im looking to do is downgrade to a 1.5. from doing a little research i think the easiest way to do this is by upgrading to a 2.71 and then downgrading to a 1.5 using something like this and then after doing that i am going to upgrade it to a custome firmware such as 3.40 O-E and then reformat the mem stick and it will have ISO folder, then put iso games in there? im really sorry for all that writing but i just really new and want to make sure i got this right.. and if this is safe enough to try.. thank you all in advance!
