The OP on this thread is in dire need of updating.
I just purchased a PSP 3000 last week and I haven't hacked one since 1.50 OFW (I had a launch PSP which was stolen years ago). I've found some info on Wololo.net but GBATemp is usually my goto place for any console modding/hacking. I would love to see this thread updated to include the new 6.61 Infinity from Davee (I read online that 6.61 was hackable on my model of PSP so I updated to 6.61 OFW before attempting). The guides for Wii and Wii U, are very informative and updated usually as soon as new firmwares/homebrew/exploits arise. This PSP guide doesn't even mention the 6.61 OFW that was released at the beginning of the year. Which puts it kind of far behind as a "Come here first!" guide.
I've had mixed sucess with hacking my 3000. I couldn't launch Davee's Maker tool due to being on OFW (I bet everyone thinks that any PSP owner that wants infinity is automatically running CFW already). I was able to run a temporary CFW program that allowed me to run the maker program, but the only place I could find 6.31 OFW was on a German site. I couldn't even tell if it was a real update file or not (It looked legit, but I don't know if it was different than the US 6.31 Eboot) but I ran the Maker program and it sucessfully completed. I transfered the file that was created to the updater and ran the update sucessfully. However, after running the updater I still was not able to launch the configuration tool (system was stating it was corrupt data). I ended up re-running the temporary CFW program again and now I can run homebrew, but the patch isn't permanent. I really haven't seen any benefit from Infinity yet because I still have to run the temporary CFW program every time I power cycle. I'm looking everywhere for info on PSPs but I'm starting to see that with the Vita hacked, there's a lot of people completely dropping the PSP (Even Davee said his 6.61 Infinity was his Swan Song for the PSP because he's switching to Vita).
It's possible that Sony could update the OFW past 6.61, but it doesn't look like that's very likely to happen any time soon. Either way, whether they update it or not there are tutorials that need to be updated to include the new hacks and such. I've been searching on this topic for the last week, and can hardly find a 6.31 OFW let alone put together a guide on how to go through this process with a stock PSP. If I had the time to write/update a tutorial I would, but I have so much going on that I barely have time to follow a tutorial let alone write one.
Sorry guys, I'm really not trying to complain. I know everyone devotes their own free time to make these things happen and I appreciate it just as much as the next guy (If not more). I love being able to emulate on today's portable consoles (I have two Vitas so I can have a 'vanilla' stock Vita and a hacked one as well) and explore all the awesome homebrew provided by the community.
If possible I would like to see the PSP forums get a little bit of action, and updating. If only just to keep up with the times so guys who are fresh into it (or like me who are just getting back into it) can be brought up to speed without spending a week researching everything.
