I had already considered this, for that I plan on useing a similar device friendtech used to replace the CPU on the xbox. (goto: http://www.friendtech.com/ and look at the dreamx)Originally Posted by psycho
as for reuseing the chip, I would like to (saves money) but I realy don't plan on it. however I DO plan on useing the identical make of chip only I will be useing the newer model (the one that uses DDR2 for its ram and nand flash) for this however the problem I plan on running into is flashing te module BEFORE installing it into teh PSP. the system must never see the change. as far as I know and am treating it, te bios probably checks for signed firmware software durring the load to flash, I dont know what it would do if it found no signature muchless no firmware.
yeah, I know.Originally Posted by psycho
no, just one. I plan on duplicateing the solder grid on the mylar. think of the mylar strips as a really thin multi layer PCB. or better immagine te circuit board for the mod literally as thin as 2 or 3 strips of paper.Originally Posted by psycho
I agree but haveing no idea what the actual logical structure of the PSP is, my best bet at this point is to completely take the firmware controle away from the PSP altogether and do it on a hardware lever... think of the level of control from this stand point: HARDWARE RAID vs SOFTWARE RAID. one (the former) is completly transparent to the host system, all it sees is a single large hard drive.Originally Posted by psycho
there are (I gather from line testing) there are at least 4 posibly 6 layers. and I will find out connection points when I get the board cleared. I am trying to obtain a nonfunctional PSP motherboard that I can completely strip and perform line mapping, then I will perform a logic probe on the functional circuits, this circuit map I will share through closed channels (sony would DEFINITELY sue me for releaseing that one!) this "map would allow professional devs the insite on the system they need to build a proper mod. and possibly I would give up at this point because the logical map is really the only thing needed to make a simpler mod.Originally Posted by psycho
no, sony has a contract lock on that hardware, samsung by legal agreement cannot release those sheets... but no such contract exists for its sister chip, which is nearly identical and the PSP should not know the diferance!Originally Posted by psycho
Hmm, interesting... Looks like a heat gun sort of... Is there any prep involved, or just heating it up? (Still have to be careful of plastic parts on the PSP board...)Originally Posted by IcoNyx
Questions: What's the part #? How much does it cost? Do you have a datasheet handy?Originally Posted by IcoNyx
Ahh, I was thinking of something a little different... That's kind of cool though.Originally Posted by IcoNyx
Well, there's plenty on Ebay. :) I have a bad board, but's it's physically damaged (bent in a way that resulted in one of the CPU chips actually popping off the board, taking traces with it...), so it probably wouldn't be much help to you anyway... I had been considering ways to get the firmware chip off the board just so I can play with it (dump the EEPROM contents, etc...). I'm trying to find a local contact at a manufacturing plant that's interested in hacking stuff. :shhh:Originally Posted by IcoNyx
Ahh... I had read somewhere that the chip was publicly available... Maybe that was before Sony entered in the contract or something... Damn.Originally Posted by IcoNyx
I diddnt say it (the chip) wasnt available, just not the tech sheet, I have no idea about the chip, but I was only looking for the tech sheet when I found out about the contract.Originally Posted by psycho
I finally got ahold of a samsung sales rep who claimed to be able to sell me the anything I needed well when we got to the subject of the chip I was requireing, I decided it prudent NOT to mention a specific chip or to mention PSP, instead I said I needed a firmware module that could house roughly 32Mb of NAND based software and contained 32MB of ram for quick access of loaded programs. he paused for a moment and then rattled off this pre-written statement "Samsung will not share patented technology related to Sony's Digital Reality Creation and PlayStation architecture... BLA BLA BLA" then promptly asked me if there was anything else he could interest me in. this was the call I had nearly verbatim 6 BLEEDING TIMES!!! I didnt even friken mention sony OR their friken 'Digital Reality Creation', whatever the H*** that is!
My mod chip idea> :humped: <Samsung... get the picture?
so anyone else got any bright ideas? as far as I can tell the PSP will require that same archetecture chip and only motorola actually makes one SIMILAR but it only has 16Mb both ram and NAND. so I am at a complete loss.
*SIGH* at least I can still make the iTrip mod with the mylar striping. right?
Mabe I could try again with a specific chip name... but I cant find that article that specifies the new chip samsung is GOING to be useing for sony... I hope I can get that one before the contract signing... anyone else know what I am talking about? if so, help me find it I need the chip serial.
funny how.. u say u going to build a mod chip.. and then this happens.. it looks like this whole thing was just for attention
[SIZE=1][B]I'm soo hot[/B][/SIZE]
[center]Sorry. No Advertising[/center]
No offense or anything man... but you shouldnt put someone down for something like this. Remember your thread about 1.51 almost hacked and you said itll only take a week more. WTF happened. its still not hacked. Just leave the kid alone. He tried to make a mod chip and realized its not as easy as it may seem. So everyone stop hating on each otherOriginally Posted by KINGOFNOOBS
i can help you i can program in c++ fluent and i can get my hands on a psp motherbord i got one i bought from online with firmware 1.5 on it for cheap
my aim is Rammstein Net12 yim is socomchat1
simmer, simmer... I haven't given up yet, just need to find a way arround this little snag. SOME company out there MUST have a chip that meets my needs, all I need now is a logical map of the chip and a chinese sweatshop that's all! seriously, Kingofnoobs... (btw, your post is not very nice. and kind of hurts.) this thread heading "help wanted" what did you think? I am doing this myself? NO I am posting here because I CANT do it myself. I was unable to procure needed materials so now it is up to the scene help me find a way arround it, so if you have an idea, then please assist me in finding a soloution. or if you dont have a soloution then cheers and encouragement are always good for moralle. otherwise dont bother posting at all. you see, if you batter and break my moralle, then why bother building a mod chip for a bunch of whiners/abusers?
and aditionally, if you think I am doing this for attention, then here is something to ponder: you are right, I am trying to get attention, and if I dont get it, I will not be able to build this chip because I am not financially capable of doing it [I]on my own[/], I am not a programmer thus cannot make the firmware needed for the mod, I am not a great hardware man ither so though my ideas are great and for the most part appear to be viable, without assistance they are just that, ideas. Heck, who knows, maybe this idea is crap, maybe some other, smarter, dev will come up with a beter mod before I even get it done. what matters here is a> I'm trying which is more than you can say b> I am putting my ideas out there where they can potentially be taken from me, with no reguard to personal gain.
If you are referring to the article that was on PSPUpdates briefly, that was an old article referring to the CURRENT PSP chip... If there's really something new coming, haven't heard about it... Here's that original article:Originally Posted by IcoNyx
Based on a cross reference catalog for Samsung, the only other 137FBGA chips in the ND256256 family are
Those are probably your best bets... Unless they are also controlled by Sony.
from the ND512256 family you have
That would be 64MB/32MB instead of 32/32, and it's dimensions are slightly larger, but it's still a 137 ball chip... It's probably compatible, but without datasheets it's hard to tell for sure. With any luck, it'd work but the PSP wouldn't be able to access the upper 32MB of the flash (but you really don't need it anyway...). But, if it COULD read it, maybe there'd be a way to store two different firmwares on the same chip and switch between them! :) (Easy to do if the EPROM and RAM weren't integrated like this, not sure if it'd be possible with these chips though...). I've been away from this stuff for far too long. :wall:
THANK YOU PSYCO!!! I have been looking for that article all evening.and as for the chips, I dont think sony can lock down samsung to that degree, I should be able to get ONE of those chips.
PSP GURU12: thanks for offering, I will keep your name in the list (pm me with your contact info)... I dont know if the PSP actually uses c++ for its firmware language but I might need your skills elsewhere.
ok, I am not going to call sales right now, I am too tired and frusterated to deal with them <grabs a soda and crashes in easy chair> but I will call them tomarrow to go the rounds again... hopefully with better luck.
as for work on the MOD, here is my plan: I dont want to work on the PSP in open air again, I am in a new houseing developement and there is still alot of particulates in the air. so I am going to build a clean room... and by the way, my wife bought a digital camera so I can start posting pics when I get going... anyway, for my clean room I am simply going to build a box out of plexyglass from homedepot. BUT before I can do that I need to finish my workbenck... which requires I finish the friken media bay... bad blast it... ok, I can do this, I need at least week or so to get going on the clean room. I need ideas for air particulates removal. but notwithstanding, lets plan on this: next post from me, I will get some pictures up of the work-site and of my PSP (for authentication of the project.) once I have the bench in place I will get the clean... uh... box, yeah, I like that, Ill get going on the clean-box. once that is done we can begin disassembly of the PSP and mapping it. now here is a "homework" list for my next post
ME: call samsung, sweet talk them into selling me needed chips and post price here for discussion of aquisition.
ME get pictures of the worksite. get pictures of materials available to me so you know what I am working with.
YOU: tell me what of the PSP I need to take pictures of for authentication, remember these are "before" pictures.
YOU: think of ideas for an air particulate removal system, I need to be able to remove dust and other debris from the air inside the cleanbox... some kind of vacuume cleaner or whatever I'm not good at this one. additionally I need to remove the particulates that are already in the PSP, my last mod attempt left the system with some dust under the cover. I know this one sounds frivolous but think of it this way, if this works and no other dev is willing to produce this mod, wouldnt it be nice if I could do it for you, and wouldnt you like me to do it w/o getting dust on your display? or "gumming" up your controls?
YOU: I need someone to start disassembleing the 1.5 and 2.0 firmwares, I need a binary file with which to flash the NAND memory. EBOOT files are useless to me. if possible it would be nice if someone could remove the encryption and signature checks from the 2.0 firmware but I wont ask for a miracle. I figure if someone starts now (if they havent started already) it should be done by the time I am ready to flash the chips.
i could write a program for the computer two tie into flashing the chip and i coulld build a live reader two see what it checks when it authenticating check you PM box i sent info i could probbly rewrite some of the firmware with hex editior CHECK YOUR PM
If you manage to come up with datasheets for any of the Samsung chips, please let me know!
As for the 2.0 firmware, unless someone can crack the encryption on the EBOOT file, it'll probably be easier to sacrifice a PSP and read the chip directly... (Not that that is easy or anything... )
Sounds like a very BIG project. Someone has to start somewhere and you sound like you know your ****. (cause I dont understand a single word of it) But its darn interresting . If I were living in your neiberhood, I'de probebly be at your place looking over your shoulder all the time.
I really wanna see some pics later on, so dont you go loose that determination.
PERSONALLY, I think this project sounds good in theory but nobody should be excited until they see GOOD results...
I don't think anyone should have anything but cautious optimism but, that's just me.
I agree. I have no idea if this is going to workOriginally Posted by exzapel
I am going to be sacraficeing mine anyway, might as well.Originally Posted by psyco
Btw, I am haveing trouble finding that desoldering tool used by friendtech and after further inspection of the chip after removal, I have a feeling that the tool renders the chip... melted? fried? bricked? :eh: so I need aditional assistance. Anyone have an idea how to remove this chip? It wont be for a while but It would be good to get the needed tools while the getten's good.
I'm not imagening a mod-chip anywhere in the near future :naughty: . Personnaly, 1.5 owners dont need one anyways.
I'm real exited about the project overall. There is nothing else but better knowledge of PSP hardware that can come out of this...and that, even if the project doesn't work as intended.
I got a wild hair and decided to check samsungs site for the needed chips. well I found several matching models... but they all show a status of "Engineering Sample"
see here for more. INCLUDEING A SPEC SHEET!:
the packages I found packace with 3 or 4 chips (depending on which package you order.) if I can get my hands on the 4 chip package I could do the project with room for error. BTW I have revisited the "how to flash it" with my engeniering friends and they apearently seem disinterested in helping... something about "conflict of interest"... so that flew down the tubes. :Argh: oh well. Undaunted, I continue.
As for a clean room (ive done this a few times in my day) all you need is a bathroom, and a shower. Turn the shower on as hot as it can get. Hot Shower = Lots of steam. Just make sure it cant vent out anywhere. Leave the shower going for about 2-5 minutes. Turn it off. Wait about 3 min, and whalla u have a clean room. This also works great for opening up hard drives
for the clean room you could always use an ionic air purifier, or maybe some kind of vacuum with a hepa filter. i wish you luck man. you have a great idea and the logic is there. maybe as a side project you can give us gps? that would be sick. just playin' but if you can...go ahead. lol. i've bookmarked this thread. i'll be checking constantly for updates. good luck young padawan, may the force be with you. (sorry, couldn't resist.)
<sarcasm>oh, ha - ha </sarcasm> but seriously, I always thought of myself as a sith apprentice... eh whatever. Ill have to experiment with a vacume. we'll see.Originally Posted by SoCalSRH
MAN! Since i last checked, this thread is on FLAMES! (Not as in a flame thread :hand: )
Can you think of how important this modchip will be? With other countries shipping with 2.0 FW, and 1.5's availability becoming less and less, people are never gonna be able to run homebrew, rather than the early birds who got the 1.0/1.5's and didnt upgrade. So ya, i say if this works, everyones gonna need one of these (yes, even 1.0/1.5 FW users). Think about it, newer games = UPDATE, PS3/X360 PSP Compatability = Possibility of a needed upgrade?) Switching between the FW's Could very well save our butt's :ROFL:
But seriously, this can work, ive been studying the inside of the PSP, and have been really thinking about taking it apart :o But i still cant find anything that would be of any use to you
Just here to keep this project alive! I havent seen this much progress happen so quick before! Seems this might not take as long as i predicted, (which was quite a bit) GOOD JOB! :clap:
Heh, I like that! Smaller RAM, so it's not going to be a compatible chip for the PSP, but, with any luck, the pinout is the same... It's a place to start.Originally Posted by IcoNyx
BGAs are pretty much only removed by a more professional version of the technique on Friendtech (better heat control and aiming basically, and the heat directed under the chip, not all over it... Obviously, they (Friendtech) aren't concerned about protecting the chip. But, if you heat it slowly (instead of blasting it with a furnace of fire), and just get it hot enough to melt the solder, the chip should survive. Again, locate and shield any plastic parts on the MB, don't want to melt other things off the board.) You might look around for old PC motherboards or video cards (or anything that might use these types of chips) and practice on them... Something you don't care about first (I'm attacking old vid & network cards this weekend to see if the heat gun I have is hot enough... ) Here's what you want tho:
For right now, you might not have to focus too hard on the clean box if you don't want to... You won't be working on anything dust sensitive (or will you? not sure about the mylars), I'd just go for it and see if the hack even works... If you are successful, you can bould the clean room for doing more of them... Just a thought tho... It'd probably be nice to have anyway.
Okay, proof of concept for step one: Getting the chips off the board! I decided I didn't want to wait until the weekend, so I went after an old network card with the heat gun from my shrink wrap machine (simple, cheap heat gun like you can probably find in a hardware/electronics store for shrinking tubbing around wires/electrical connections). This was the result, and it was surprisingly fast:
These chips just started falling off after only a few seconds (on high) with no apparent damage to anything (nearby plastic things got soft, but if you don't touch them, they should cool back down fine). Note: Probably not best to hold circuit board vertically, the chip could slide through the hot solder leaving trails all over the place requiring extra cleanup... As can be seen on the back of the larger chip and the board above it:
So, after this step, there's some clean up obviously, but it worked well. For our purposes, no worries (but when I applied upward pressure to the smaller BGA chip in the picture, I pulled up a trace from the back of the chip (notice the missing ball-pad in the upper-left corner...). The PSP chip isn't built like this tho.)
And, as you can see, for de-populating the entire board, this will work rather well. I basically just brushed all the little chips off after heating the area for a few seconds (like maybe 10 or so... probably 30-40 seconds on the BGA chips).
mmmmmm, lovin the results, when i was like 12 (about 3 years ago) i had no experince with any hardware at all, i used to try prying them from the board
Wow when I first read this I was a little sceptical, but know I must say u are going to go through with this and I have a feeling that this gonna rock. I just cant wait to get my hands on this. Just give me this mod and internal hd and i would be set for life! :Jump:
But would it seriously be possible to make a HDD for the psp?Originally Posted by bigmace0309
Possibly from an iPod?
well i was wondering if u could mount an ipod mini 4gb hd inside the psp it is only an inch wide and i think a few cm thick(not sure on the thickness). With executers mod hopefully it would be possible to atleast get it work with the psp. Even if i have to attach it to the outside and build some housing that would be sweet. but who know even if the psp could recognize it.
You wouldn't imagine how much I would appreciate a Hard drive on my PSP, internal or not...
You should try rewiring the MS Duo slot and then when you insert a duo, it functions like a mod-chip. It loads a BIOS off of the MS Duo or something...
