Okay, so Sony fights tooth and nail to friggen stop us from using our little PSP's to their full advantage. This is something I did not realize when i went out and impulse bought myself a PSP specifically for the purpose of playing homebrew (SNES and PSX mostly). I've always wanted a portable nintendo damn it! (don't tell me "gameboy")
So i get home and start doing research, within the first ten minutes i followed bad instructions and shorted my battery trying to make a pandora (don't charge it before you open it, derp.) it's probably good i broke the battery, 'cause if i had rushed ahead with the install method i probably would have bricked my TA-082 motherboard using the wrong downgrader.
So i've done some more research since then, and the most promising method seems to be the TA-082 2.71 downgrader method using HEN-D, the guide for which is on this site, and can be found here:
.... ooops, apparently i need 15 posts before i'm allowed to post url links... even to this site.... that..... is..... retarded
Now, i am still waiting on my Pandora's Battery (Datel TOOL battery) and it should be here in a couple days, i assume this method requires such a battery (although the method does not mention it)
I tried to do this mod anyway, about five minutes ago, but it does nothing (when i go to display the "rand.jpg" picture on my psp, it actually SHOWS the picture, and the "loadbinary.tif" file reads as "Corrupted Data")
I'm working under a hypothesis of two possibilities here, either this downgrade method requires the pandora's battery to put the PSP into service mode first, OR this method simply has been out-engineered by sony under 3.93 (or perhaps 3.90 and up) official firmware.
While I am impatient to downgrade my PSP (after all i didn't even want one until i realized i could play my ROMS and PSX iso's on it) I am willing to wait for a stable tested method of downgrading the 3.93 firmware.
I have spoken to an individual online (who shall remain nameless) who says he has successfully downgraded his 3.93 firmware, and that it is in fact possible, however during our discourse he did not tell me which method he used, which downgrader he installed, or whether he has a TA-082 troublsome ass motherboard. I am awaiting further reply from him, but i do not expect to obtain all the answers from one source. He's a busy man anyway, and i've been asking a lot from him.
My questions to all of those out there (Especially you PSPmod.com moderators and site administrators) are these. What's the word on 3.93 downgraders? Is work progressing? Has anyone sucessfully downgraded a 3.93 firmware using methods designed for previous firmwares? And if so, can you provide links to the guide?
Since i feel i am pretty far from the only person seeking this information, i hope this thread will receive a lot of posts, but i don't necessarily expect anyone to come up with all the answers, we ARE dealing with reverse engineering a proprietary system here. When my pandora's battery arrives i will try the 2.71 ta-082 method once more, and post the results here, so if i brick my PSP, you'll all be the first to know.
