NEW way to make Pandora's Battery w/o solder!!!

[redryno1221]

I did not create this tut but wanted to share it


Ok, so you want to unbrick or downgrade your PSP but don't have a PSP capable of running homebrew apps. No problem! In this tutorial I will show you how to modify the battery's hardware to make it activate service mode.

This is our victim. Please note that while this concept may work on non-Sony batteries, only official batteries are guaranteed to have the same internals, so we recommend using one.

STEP 1:

The first thing you need to do is obviously crack open the battery. Surprisingly, the battery isn't very hard to get in to. In this picture you can see that I'm just using a guitar pick to slide in through an edge and slide around the perimeter of the battery to seperate the two halves.

STEP 2:

Next, we need to locate a certain chip. The chip has the model number S93C56 printed on it. We are going to need to desolder pin 5 and lift it off of the board. Here is a magnified view of the board, which shows where the chip is and which pin needs to be lifted.

Newer batteries have a much smaller board with a different layout. The same chip needs to have the pin lifted, but the chip is in a different position. Once you've located chip S93C56, the rest of the instructions are basically the same. This has been confirmed with the 2200 mAH Official Sony battery.

STEP 3:

If you are not confident in your soldering skills, have a less than steady hand or have a larger-than-optimal sized tip, please desolder the cell pack from the battery first. If you make contact between pins 5 and 6 then you will short ground to +3.6VDC! Not good! When desoldering the cell, only keep the iron on long enough to melt the solder. If you can, use a higher wattage iron so that the tip will be hotter, but you won't transfer as much heat to the cell pack. Remember that heat + Li-Ion battery = large explosion (t3h sux0r5, unless you get in on video. Twisted Evil Seriously though, this operation is not for the faint hearted, and should definitely not be your first soldering experience. I recommend trying your hand on lifting the pins on an N64 CPU chip. Surely if you spend enough time here you have a couple killed N64 mobos laying around. Razz)

Now is actually desoldering the pin. There are a few ways you could do this, but I think my method is the best because its less likely to damage components near by. Use an Xacto knife with a sharp tip and try to put it underneath the pin. Get somebody to hold a soldering iron (WITH A VERY FINE CONICAL TIP!) on the pin. When the solder melts you can pop the pin up with the knife. Be sure not to hold the iron on the board too long to avoid the lithium battery from getting too hot and exploding. When your done it will look something like this.

STEP 4:

Finally, close the battery's casing. Use some Krazy Glue to keep it closed, or just use electrical tape around the edges like I did. I don't actually recommend the electrical tape as it makes the battery very snug in the compartment and it takes a bit of force to get it out. You can use the battery just like a regular Pandora's battery. As for getting the Memory Stick files, I can tell you that they are out there and you can find them after a bit of Googling. However, I can't tell you exactly where to find them as they contain copyrighted Sony code, and sharing them is illegal.

How does this work?

The pin that we just lifted was actually the ground pin of the EEPROM. Removing this pin effectively shuts off the EEPROM. When the microcontroller inside the battery tries to read the EEPROM, it will think the EEPROM contains all 1s (in binary). This is because of the pull-up resistors on the data lines. So the microcontroller returns a serial number of 0xFFFFFFFF to the PSP, which then goes into service mode.

Thank you for reading this, and if you have any questions, make sure to post and I'll try to help you!




That's it..... Thanx to Iam7805 for the tut and Richlik for finding it....and myself for posting it. 


P.S. can someone put this in the tut section???

[spelman07]

U r a :censored:ing legend mate it works!!! saved me buying one

cheers

[ndrew2505]

old news. i have 1 of these i made about 3 months ago.

[MattZani]

yep, released like 2 months ago.

[IndyChav]

nice tut

[FreeK]

hey redryno

isnt this the same exact tut right here, just maybe worded a little dif?

[Grantlionheart]

Is there a way to tell which version of a battery you have without opening the battery up?

[ndrew2505]

all sony batts should have the eeprom in the same place. after market batts are way different so unless you know what eeprom ics look like dont attempt w an after market batt.

Please note that while this concept may work on non-Sony batteries, only official batteries are guaranteed to have the same internals, so we recommend using one.

[Grantlionheart]

Fried my battery trying to do this. Oh well.

[custm_made]

can't you just cut the pin. isn't that doing the same thing.

[ndrew2505]

the whole point of just lifting the pin is that if you ever want ur normal batt back all you have to do is resolder the pin or even put a switch on it.

[bormann]

wow that pretty easy
cheers :P er

[redryno1221]

^just as long as it isn't touching it should work...

^in theory you can put a switch on it...

[mootoo]

great thing mate ,maybe i try build in micro switch .

[custm_made]

whats a witch and how do you install it.

edit*
wtf!!! i just opened up my psp battery and it doesn't even have the circuit board to create a pandora battery. it has this small, thin circuit board running across the top of the battery. (where the little connectors are) and that circuit board doesn't even have the chip where i can remove the 5th pin. can someone please tell me where i can get a battery that has the type of circuitboard that is in the pic. i really want to make a pandora battery....please help me out.

1Sniper- Plz dont double post

^your best bet at getting a real Sony battery would be like walmart or gamestop or Llama.com (he's a fellow hacker)...

[custm_made]

yeah, i guess ill get one from there. if it doest have the circuit board that i need, then im going to be pissed.

thanks anyways tho.

[redryno1221]

^don't buy a batt from dealextreme because it doesn't come with a circuit board 

[custm_made]

do you know what battery to buy. (2200, 1800, ect.)

[redryno1221]

^ I'm pretty sure it only works with 1800 but it may work with the other one to... 

[custm_made]

i have a 1800 and this is what it looks like.

1Sniper- plz hyperlink your links

First of all next time to upload a pic do this pic url 
and I have no clue how you would be able to make a pandoras batt out of that where did you get it? 

[custm_made]

thats the one that came with the psp when i bought it. i bought it over a year ago so it shouldn't look like that.

[redryno1221]

No someone must have bought a cheap ripoff of the official batt... does it say sony on the front of the batt (on case)? Where exactly did you buy your psp...

[custm_made]

the battery says sony on it. i bought my psp brand new at walmart about a year and 1 month ago.

[redryno1221]

the battery says sony on it. i bought my psp brand new at walmart about a year and 1 month ago.

^hmmmm... not sure what to tell you...  does it look like the batt in the tut (all the writing on outside)... I'm not sure why sony would give you that batt... 

[custm_made]

the case looks just like the one in the tutorial and says the same stuff. how old is ur battery?

[redryno1221]

It is about a year old but I have also taken apart several other batteries from my other dead psp's and they all had the microchip... not sure what's up with yours 

[custm_made]

.......i had to get the retarded psp...

[redryno1221]

.......i had to get the retarded psp...

LOL  ... but if you do order a batt from llama.com or buy one anywhere else then you should be able to do the pandora's batt and dwngrade any psp
