PSP Multi Firmware Project

Today received the "PSP Multi Firmware module" Sample PCB
i Will test it tomorrow, if every things is ok,
will start to produce ^o^

Note : this is not a [mod chip] Project
and it can't Downgrade PSP FW 2.50/2.60/2.70

my 6 set PSP ^o^

1st PSP w/ FW 1.00

2nd PSP w/ FW 1.00 update to 1.50

3rd PSP w/ FW 2.50 Multi Firmware Mod 50% success (can't use FW 2.00, 1.50)
　　　　external FW 2.50, 2.60, 2.70

4th PSP w/ FW 1.51 Multi Firmware Mod 100% success
　　　　external FW 1.50, 2.00, 2.50, 2.60, 2.70

5th PSP w/ FW 2.50 Multi Firmware Mod 50% success (can't use FW 2.00, 1.50)
　　　　external FW 2.50, 2.60, 2.70

6th PSP w/ FW 2.01 Multi Firmware Mod 100% success
　　　　external FW 1.50, 2.00, 2.50, 2.60, 2.70

about 50% success :
in new ver PSP (FW 2.50/2.60 from factory)
it use new "protection"
maybe w/ new bootloader ?
so it can not use old ver FW
if you paste old ver FW in it
it will not boot

new ver PSP (FW 2.50/2.60 from factory)
it just can Upgrade
and can not Downgrade !!

2.60 new "protection" :
if you replace the flash0/vsh/etc/index.dat w/ old ver index.dat
when you power-on you will get a error screen

2.50 new "protection" :
if you replace the flash0/vsh/etc/index.dat w/ old ver index.dat
you will can not lunch update EBOOT.PBP

on FW 2.xx you also can not replace [new ver PRX files] with [old ver PRX files]

if anyone need 2.60 FW dump
you can use PspPet's PSAR Dumper w/o Decrypte to dump it
the dumped file is same as file in PSP NAND Flash(except "SIG check key")

It´s not possible to downgrade from 2.6 to 2.0 or 1.x
But why don´t you downgrade to 2.01 and than to 1.5?

HaQue · Post by **HaQue** » Sun May 07, 2006 11:20 pm

well.. off topic really as this is a multi-firmware mod, NOT a downgrader. Please don't get the thread off to a bad start.

But to answer your question, 2.01 cant be DG and all versions above 2.0 can't be downgraded to anything at all.

Now lets stay on topic please!

Hagbard90 · Post by **Hagbard90** » Mon May 08, 2006 1:25 am

a multi firmware mod?
This means, I can use on my ,for example, 2.01 firmware the 1.5 firmware, but it stays the 2.01 firmware, right?

HaQue · Post by **HaQue** » Mon May 08, 2006 3:46 pm

Im usure why the first post by 0okm0000 doesnt answer your question... but if yours is 2.01 then it does look that way.

as you can see, there is a fair bit of work to be done to your PSP before you can use multiple firmwares.

BTW, if you cant afford 6 PSP's you need to take in the "other half" factor.

I was looking at 0okm0000's cool pics on the first post and my GF said (rather loudly) Don't even f#### think about it! damm!

kyriptic · Post by **kyriptic** » Tue May 09, 2006 8:50 am

hmm.. did i miss something or did he not test the firmware mod on the 1.0 and 1.5 and trying to run 2.0+ fw's on it?

HaQue · Post by **HaQue** » Tue May 09, 2006 6:44 pm

I probably wouldn't risk ruining a 1.00 or a 1.5 either, Im guessing thats probably why.

It isn't really needed anyway, except for exprimentation as having a higher firmwared PSP with the capability to do any firmware below it is fine, "in production", just upgrade to 2.01.

5th PSP w/ FW 2.50 Multi Firmware Mod 50% success (can't use FW 2.00, 1.50)
　　　　external FW 2.50, 2.60, 2.70

When you have tested this, have you swap the WLAN card,
I mean the MAC adress is known by the firmware.

mmm you cannot use this for 2.5+ but what about this

a bricked 2.5 psp

is this going to work?

and if you dont know sell me a flash card with a 1.5 firmware and i will try this

Where did you get a samsung 32Mb NAND flash chip from 0okm0000?
The ones I can find is 64Mb+

digihoe · Post by **digihoe** » Wed May 17, 2006 7:41 pm

0okm0000 and all others I know I asked this in the old now locked thread, but the answer I got was not to my satisfaction... About using bigger RAM, I found out that the development unit has 64 mb for main memory, I don't know if that suggest only flash or both RAM and flash.

My guess would be that the PSP should atleast be compatible with a 64mb flash...

Any thoughts on this?

dot_blank · Post by **dot_blank** » Wed May 17, 2006 8:18 pm

yes the DEM-100 units carry 64MB
but you cannot just upgrade your psp
with more ram/nand so get the thought
out of your head it just cannot be done
look at the ram lines on your psp mainboard
do you think that you can lift those off successfully
and then lay them down (all being same length from
cpu and still think that the 64MB chip can operate
well if even slow :P ....no i dont think you have
the hardware to so ...because nobody does
so deal with the psps 32MB it is fine and you
really arent going to succeed with trying to upgrade
the RAM/NAND chip

your energies could be used for other activities so
just drop the thought off your mind

groepaz · Post by **groepaz** » Thu May 18, 2006 7:24 am

well atleast one guy has succesfully removed the flash/sram chip, reballed it and added a passthrough switchboard in between the board and the chip. ofcourse few ppl have the technology needed, but that doesnt mean its entire impossible :)

dot_blank · Post by **dot_blank** » Fri May 19, 2006 4:31 am

removing the nand chip is one thing but removing
the copper traces to and from cpu to nand is another

digihoe · Post by **digihoe** » Fri May 19, 2006 5:40 am

Please dot_blank consider the length of the RAM traces at the ball point... They should be the same length if SONY did a good job... Why do we need to cut them, when we can extend them? Sure it will give a small preformance drop...

Sorry for going of topic... Will move my energies back to my studies in organic chemistry and forget about more RAM...

Best regards!

dot_blank · Post by **dot_blank** » Fri May 19, 2006 6:55 am

your best bet if you really wanted to persue the RAM expansion
would be to manufacture a board to set on top of NAND
pins (a very thin board please! :D ...just like how mczonk
is doing with a dual firmware ...but instead of having two
chips you could have just one big fat chip ....and lines of equal
length from nand pins to the chip pins ...to insure latency
and well that is the only way its feasable ....otherwise no ;)

The PSPs I pulled apart (Australia) had the MAC addresses stamped into the
metal shielding of the WLAN card. For that reason, I also assumed the MAC
address was stored in the card.

all daughterboards have the MAC stamped

Hi everyone,
Thanks 0okm for the info .
But can you (0okm) please give us the schematics of the NAND Flash Programer and the PSP NAND Flash Adaptor ?
and in the schematic draw of the psp multi firmware project, what do you mean by the cross (X) mark between CE of the nand chip and the PSP CE ?
also, will it work and can I try it on my 1.50 psp with a 2.70 firmware on the second (new) chip ?
And at last, can you tell me where can I find the nand chips for sale ?

And sorry for my English and Thanks Again :) .

HaQue · Post by **HaQue** » Sat May 20, 2006 3:24 pm

The X mark is to cut the trace there so the switch will work as a switch. Just visualise what will happen whe SW-DPDT is in both positions...

I would like the schematics as well, and a couple of chips to play with!

Hi ,
I bricked my psp while trying to update the firware .I cant send it to sony since im from india. can u help me build a nand flasher .

digihoe · Post by **digihoe** » Mon May 22, 2006 10:43 pm

0okm0000, is it possible to use your hardware setup to read the RAM (or maybe just record the traffic between RAM and CPU...) while updating a second flash to 2.7 and maybe gain keys?

Best regards!

I know someone with a test station unit and there is a option to switch from 32mb to 64mb memory mode. However, when switched to 64mb apps such as the eloader do not work anymore

It may be possible but who knows if the PSP will actually take advantage of that extra ram, as in the user 2.6 firmware there is no option to switch memory mode, and test station firmware cannot be installed normally on a retail PSP.

success to make soft-swap PSP NAND Flash ^o^

late i will look for a factory to production this "PSP Multi Firmware module"
i think they will sell it under USD50- :P

What a great news~!
We're all looking forward to that comes out~!

But did you solve the problem about the new ver. hardware can't downgrade to lower version firmware?
