A: invest in some punctiouation

B:Yeah, your PSP might not be a able to get CFW, it could have a TA 88v3... in which case, CFW is not an option.

get a pandoras battery and hope for the best

to quote the french
"cest impossible"
there is no downgrader for 5.51, chickhen doesn't work on it, your only hope is that you don't have a unhackable psp, and can use a pandora battery

Currently impossible if I'm correct. Don't worry, be patient and there is bound to be a solution to your problem eventually. People thought the 3000 would never be hacked, and looked what happened today...

if you upgraded to 5.51 there is a good chace that you can still hack it using pandora, three questions:

what was the firmware at time of purchase?

is it a 2000 or 3000?

if it is 2000, what is the mobo version?

[tmbm]

its a psp 200 installed with 5.00 stfu he cant install anythin!

[biffmaster5000]

its a 2000 and how can i check to see what mobo is in it besides takin it apart and reading the #'s?

[tmbm]

yo biff wats ur firmware? plz

[biffmaster5000]

i have a slim 2000 with 5.51

[tmbm]

if its 2000 use a pandora battery, buy 1
if its a 2000 v2 v3 no chance of buyin a pandora
