hi,
i upgraded my psp firmware to 4.05 and now my .iso files dont work..
How can i downgrade to my previous firmware(3.71m33), is this possible or there is another solution

Hmm... Just a suggestion, but you could start by reading the thousands of posts on this forum regarding Pandora, or simply punch "custom firmware" into google.

how did you upadte it? did you use the "network update" feature on the PSP? if so you just went from CFW to 4.01 OFW, adn cant run ISO's anymore. 3.80M33 changed the netwrok update feature so it woudl update to CFW.

i think that is what you did, since there if no 4.05CFW AFAIK. your going to have to downgrade again with a pandoras battery and MMS

well it looks to me like you have went from CFW to OFW downgrading is only possible with a Pandora battery and a magic memory stick
