yeah everyone should now that.
I'm not super sure how well putting a pointer in a bios goes...
From what it sounds like on the WEP cracker project, the PSP strongly dislikes having new pointers (i.e. it bricks almost everytime)
But it might work in the Flash1.
And for the record 12 bytes is no where near an update which is about, 12mb or 10,000 times that size.
Also we need to keep in mind that it is 12bytes per transmission, not tottal, sorry if I confused anyone there.
And if anyone happens to stumble across what version of libmng the PSP uses please be so kind as to share. (and yes I mean libmng, not libpng, it's the animated version of .png and is probably a lot more likely to be useable)
An update is .......... between 12 and 20-ish megabytes, not 12 kilobytes.
Freeplay,
an normal update is between 12 and 25 megabytes. However how big has an program to be that read's an full version flash from memstick/umd? All they need is an mini kernel. An kernel can contain a reader for the memstick/umd, a NAND-flasher and some screen output. It could be that is all they use.
Such a program could be just 1 megabyte big.
So cant we do a couple of transfers since you can transfer 12 bytes, just do it more than once until you have transfered all the data you wanted, but this may take a while.
But the problem with that is once you clear the NAND there are huge risks of it not receiving anymore signals.
So ideally, squish a pointer in 12 bytes to get it to do the rest from the ms. Nearly eliminating the brickage.
Even still, the new Tiff exploit looks promising if it can run code.
Only a little more waiting either way.
Probably a dumb question but..
Back in school, when I had C++ class... when we worked on linklists, we had to get memory from the OS. I don`t exactly remember the code for it... I think it was like newName or something like that. Anyways, couldn`t we use that 12 bytes to ask the PSP for more memory to use?
So what is this new tiff exploit? Any info on it? I really hope the day I get to downgrade comes soon.
New Tiff exploit? Cool, maybe homebrew is nearby
Uh, all info on the new tiff exploit is in the Dev section
Yeah and is better than serial because a cable would not be required.
True dat. Let's hope it works!
where is the Dev sectionZitat:

I would do that because I have a chance to make lots of money. :tup:Zitat:

If you guys want to infom me of something, I suggest you PM me, AIM me, MSN me, or Email me. I havn't looked at this topic for a while, so please use IM to get my fast.
I'll see what I can do about finishing off the cable as quickly as possible, I havn't had any time to do anything with it recently.
Finally a response from VB Master!
is vb master talking about making a serial cable for the psp
thats old news, sorry but it is, and i think the schematics on how to make them is on the Internet to
just look at this place
nil.rpc1.org/psp/remote.html
that page has been around for ages, btw vb master what is it you are making or have made, i really don't want to flick through the last 30-50 pages to find out, could you like give me an update about what's happening, that'd be great:tup:Zitat:
Zitat von sigudian
i think he making a serial<->serial cable for the pc to the psp or a serial<->usb cable, and both of those is nothing new.Zitat:
Zitat von Skyline34
thanks for the update:tup:Zitat:
Zitat von sigudian
anyone have an update on the progress of this? Has the dump been thoroughly searched through?
I am making a Serial to PSP cable In fact, I am using that guy's schematics! Hopefully it lets me flash the PSP.
Hopefully the LibTIFF exploit works.
how are you trying to access the nand?
Through the serial since it's connected directly to the nand.
yes it is, but it was not the answer to my question.Zitat:
Zitat von TrumpeyGeek
how is he gonna access the nand ones he has the serial cable connected up?
If Sony uses the cable to get into a recovery mode, then we can use that and get there too.Zitat:
Zitat von sigudian
thats true, but you cant just connect the serial cable to your psp and pc, and then magically you go into a flashing of any FW....Zitat:
Zitat von vb_master
anyway you need some type of software in the pc end
Well, obviously. The software end shouldn't be that hard.Zitat:
Zitat von sigudian
your the first one I've ever herd said this about that topic.Zitat:
Zitat von vb_master
but i wish you good luck, cuz i realy want it
Lol, you might want to try coding it before you say that.Zitat:
Zitat von vb_master
PSPLink seems to be a good start, so if you were lazy just modify that.
But I still don't know how you intend to write to it through the serial. Because to my knowledge the serial port just sends little snipits of codes for basic functions. I think you would still have to find an exploit, which would be quite hard since all you are using is basic hex comands.
Best of luck though.
Maybe we could use the Epsilon Bios and modify that.Zitat:
Zitat von sigudian
if this cable works we can fix bricked psps! Yea!
yeh, but its main intention is to downgrade 2.7+Zitat:
Zitat von rai1790
I personally think it won't be that hard. Perhaps the PSP remote will kick it into USB host mode, then connect a USB cable, and perhaps it will flash like that? Makes sense.Zitat:
Zitat von RoninRevolution
Whatever, the coding will probably be hard.
Most likely they will upload an special bootloader to the flash. That bootloader could read the ms/umd/usb. However an umd will be more logical.
Probably, since we can't make our own UMDs. It (would) be the safest way.
However, if we can get to the flash, everything is open anyway. Unless there is unknown hardware protection as a few people mentioned earlier.

Hey TO I PM'd you about the cable. I'm going to try to finish it today and test it! WISH ME LUCK!
*wishes vb_master luck*
I hope it works.
*crosses fingers*
keep us updated vb
Anyone got the pinouts of an official PSP remote, or do I need to trace them myself?Zitat:

Edit: got them from here, soldering now!
Good luck on this
