Hello. I would like to ask for help / guidance to solve the problem described in the topic with error 80010017. In a nutshell, the matter is this way: last year, friends with children came to us, I started the PS3, started the MM, showed what and how and went on "grill " I said on the drop-off: do not update the software. As you already guessed, and I read it; I already have 4.82 on the console, unfortunately. From time to time I like to play DIRT 2, 3 on the steering wheel, and I do not want to have a brick-swap console. please help / guide. I had CFW Kmeaw 3.55 and that's enough for me. I learned that the only option is HFW. But how? To the point: as I wrote above, I already have OFW 4.82, I can go back through HFW, unfortunately I can't suck 4.82 HFW although it seemed the most logical to me. So I have 4.84.2HFW prepared. This is a list of steps: 1) I have checked MINVercheck and can install up to 3.45 so it's fine. 2) "whistle" to the right USB connector (fat32); 3) Installing 4.84.2HFW as PS3 / UPDATE / PS3UPDAT.PUP with XMB and the same again with recovery 4) I go to http://ps3xploit.com/ I choose NOR (because I have such a memory) 5) I set the above page as the default I clean the browser and close it. 6) start the site, choose "Initialize exploitation" and wait for success 7) Then "Trigger the exploit" and wait for success 8) and what next? I need to install this flag change program - Habib QA Toggle 4.21+ v1.0 by Habib? 9) then what next? Install CFW 3.55 kmeaw via XMB as an update and a second time with recovery? 10) Re-installation MM and ready? Theoretically, all these steps are just software updates so IMHO should all be left on disk - data and files.
