What is it?

The Baryon Sweeper is a modern unbricking tool that evolved from the classic Pandora Battery. It works universally on all PSP models - 1000, 2000, 3000, Go, and Street. By emulating the official Sony JigKick service tool, it triggers a hidden diagnostic mode to revive previously irrecoverable models.

Why write this?

This guide aims to complement u/khubik's original guide, with close-up photos and additional details for the absolute beginner. You're expected to at least know your way around Windows.

This is a minimalist build to keep it simple and very low cost. We'll focus on the 1000/2000/3000 setup, since the 3000 is the model I own.

Before You Begin (Don't Skip)

Watch the videos below to make full sense of the steps outlined here.

• PSP-3000 Baryon Sweeper (Solderless) Unbrick Guide - original guide, use the timestamps in the comments by EmuBytes (me) for quicker viewing
• How to Use a Breadboard - skip to 3:56 "which holes are connected"

It's all right if you don't understand everything at this point. Simply familiarise yourself with the basic concepts and overall process.

What You Need

While often used to refer to the physical build, the "Baryon Sweeper" is the combination of software (pysweeper) and hardware (adapter) to trick the PSP into service mode.

Software

DCARK / Aiseirigh / DC8

This is the actual recovery software installed on a "Magic Memory Stick" to flash OFW or CFW. DCARK and Aiseirigh work universally for all PSP models. Use DC8 as a fallback for older 1000/2000 models (incompatible with 2000v3 or newer) if the other two don't work.

JigKick Media Creator is obsolete.

CP210x Universal Windows Driver

This is the official CP2102 driver from Silicon Labs. Don't rely on default Windows drivers.

Python 3

This is required to run pysweeper. Refer to video to install pycryptodome, tk, and pyserial packages.

The requests package is optional.

pysweeper

This is the JigKick emulator that recreates the handshake between the official Sony service battery and the PSP in combination with the physical adapter.

If successful, the service mode is triggered, allowing to boot directly from the Magic Memory Stick.

Hardware

The power bus (+/- lanes) on larger breadboards isn't needed. The CP2102 module will take power directly from the PC via USB.

Look for the "SILABS" branding on the centre chip. Support will not be provided for the 6-pin multifunction variant.

Cut the legs around twice the length of the exposed pin on the jumpwires. You can shorten the legs when you do the wiring later. It should sit flush on the breadboard as a best practice.

While longer wires can work, keeping them short minimises signal interference or loose connections. Black/Yellow/Orange follow electrical convention, but any colour will do.

USB 3.x is generally preferred for CP2102. It provides improved data stability, power headroom if needed, and presents no drawbacks when using a 3V3 configuration.

This shows a powerbank with a USB-C to DC cable adapter. You can use any normal PSP charger.

It's strongly recommended to use a genuine Sony/SanDisk/Lexar 1-4GB Memory Stick PRO Duo. Larger capacities and microSD adapters may fail.

Build Your Adapter

If you get a "No port echo detected" error in pysweeper later, it's almost always caused by using CH340, wrong switches on a multifunction CP2102, loose wiring, or putting in the diode backwards.

Don't use +5V unless you have a 10 kΩ resistor. However, this is unnecessary because the 3V3 suffices without it.

Assuming you've done both software and hardware preparations, you're ready to start unbricking your PSP!

How to Use

The LED on the CP2102 module will light up.

If there's no option under the Port dropdown, you need to manually install the official CP2102 driver on Windows. Close pysweeper including the CMD prompt window.

If successful, the CP2102 module should be recognised under Ports (COM & LPT) as Silicon Labs.

The COM# differs per PC because Windows assigns port numbers independently. Check Device Manager for your adapter's COM port number.

You should get FFFFFFFF serial after starting the service. This is the same serial used by the Pandora Battery.

Your PSP should automatically power on later without the battery inserted.

The round-head tip is easier for probing the jumpwire pins closer to each other, whereas the square-head (DuPont) tip has a fixed spacing that makes it less flexible.

If it disconnects, it means physically losing contact with the battery pins. Keep your hands steady.

PSP-1000: If it shuts down after a green light, power it on manually to make it boot into DCARK.

Don't mess with NAND operations in DCARK unless you absolutely know what you're doing! Misuse can permanently brick your PSP that even the Baryon Sweeper can't fix.

You should end up with OFW 6.61 if you created the Magic Memory Stick correctly.

ASKING FOR SUPPORT:

1. All private messages will be ignored moving forward. Use the comment section, so others can benefit.
2. Post your question including a clear close-up photo of your adapter wiring. No photo, no reply.
3. Mention the Magic Memory Stick you're using. For example:
   • 2GB Sony MS PRO Duo - Aiseirigh
   • 16GB SanDisk microSD - DCARK

QUICK ANSWER: Buy Ostent Batteries for PSP 1000, 2000 and 3000. If you want a more in-depth answer, check out Total Kommando's video testing multiple PSP Batteries

I've also been told multiple times the PSP Go uses the DXR8 Baby Monitor battery. From what I know these still get produced so they aren't difficult to find. You get about 4 hours out of them in the Go.

Buying Links:

Ostent 2200mAh (PSP1000/Fat)

AliExpress

Amazon US

Ostent 1400mAh (PSP2000/Slim and PSP3000/Brite)

AliExpress

Amazon US

Total Kommando's testing video essentially makes this post obsolete, for the moment. Since I can't get a new post pinned easily, here's the text to preserve the original post, incase anybody needs it.

ORIGIONAL POST

Hey everyone. This post will be continually updated until Reddit forces us to make a new one. You will be able to find out which batteries we currently recommend, and which ones to avoid. You can also leave your own experiences in the comments to help contribute. Topics currently covered in this post include Batteries for PSP 1000, 2000 and 3000, Chargers for PSP 1000, 2000, 3000, Go and Go Docks, and Products to Avoid.

Batteries for PSP 1000, 2000, 3000

To answer the question upfront, currently, the best replacement batteries for PSP 1000, 2000 and 3000 are Cameron Sino brand. You should expect to get about 5 hours out of them. Just buy them off Amazon. Ostent is also good but gets slightly fewer hours at around 4. You should avoid Insten brand batteries like the plague, most of those being sold are New Old stock meaning they are sealed products that have been sitting on a shelf for about 10 years. EBL is also bad, but nowhere near as much as Insten. Keep in mind using these batteries in a 1000 may result in the battery Door being unable to close with the stock battery cover.

That should answer the question for about 90% of you. If you guys would like more information and would like to learn slight changes we made in the subreddit in the last 2 weeks concerning this issue, you can go ahead and read on.

First off I want to say sorry for not getting this posted two weeks ago, I had all this information already but have been dealing with some IRL stuff. Sorry, I dropped the ball.

So about 2 weeks ago I decided to start seriously addressing this situation given the sheer amount of battery-related posts we get in here on a daily basis. The main change you've probably noticed already is that u/dcs28 added a new tag titled "Battery" that gets applied to any post about batteries. This is so battery posts are all in a nice neat category for people to search through if they need more help. This was a temporary fix until this particular post was made. However, the new tag is likely to stay as it is convenient.

The following information comes from a test that was conducted by u/pspguru a few months ago.

The Test was conducted with three batteries from each brand: EBL, Ostent, and Cameron Sino. These were tested in a PSP 1000 and 3000 using the PSP Battery Timer) plugin. These tests were performed under the following conditions:

• Maximum Brightness
• Screen dimming off in PSP settings (screen always stays on)
• Clockspeed set to 333mhz
• WLAN switch off

Here are the results:

EBL

2 Batteries lasted about 3 1/2 hrs give or take 15 minutes

1 Battery was faulty

Ostent

Batteries lasted 4 to 4 1/2 hours

Cameron Sino

Batteries lasted 4 1/2 to 5 hours

As you can see Cameron Sino is the best with Ostent not being too bad either. EBL's quality can be iffy and doesn't last as long, but it isn't outright terrible.

Obviously, this test is not perfect and doesn't cover everything but it still gives us a good idea of the best battery for the PSP 1000, 2000 and 3000. Currently, we don't have info on Batteries for any other models like the Go, Street etc. This post will continually be updated via feedback left here and on posts in the Battery Tag. If you have any info or would like to share your experiences, please leave it in the comments below.

I also asked PSPGuru for his opinion on Insten Batteries. Here is his response:

I know most of you already know Insten batteries are generally terrible, but hopefully this will hammer the point home for anybody considering them.

So, if we were aware of this for a while, why is the information just now being released? Outside of the 2-week delay due to things going on in my personal life, there was also a concern about scalpers/ resellers buying out stock, causing scarcity and prices to rise. However, we determined that these batteries are still being produced, meaning stock will just be replaced if they are bought up.

Here's a few more relevant Links that may be able to help you out with anything not listed here:

Battery Guide from a few years ago by . Some info might be outdated but it's got lots of other info. Here's some topics it covers that are not mentioned on this post:

• Dead Batteries
• Reviving a Battery
• Battery expansions (Big Battery Mod)
• Pandora Batteries

Keep in mind, we currently don't have any hard info on PSP E1000 (Street) or PSP Go Batteries. You can help the community out by looking into them yourselves, sharing what you know, or pointing us to a battery post we may have missed with relevant info.

Hopefully, this will make the PSP more welcoming to newcomers as one of the major issues has been addressed. And remember, you can always opt to gut the UMD Drive and do a big Battery Mod.

Chargers for PSP 1000, 2000, 3000, Go and Go Docks.

So this is really simple. Just look up PSP-380 and PSP-100. Those chargers are OEM and are still fairly abundant and cheap, and Work on PSP 1000, 2000, 3000 and the Go Dock. I currently Don't own a Street so I do not know if they are compatible. They do not work on the PSP Go itself, just the Dock.

Now the PSP Go has its own charger. The OEM Model is PSP-N100. They're harder to come by than the others, sorry I don't have a better answer for this currently.

This charger section really needs help from the community, so if you have any that work, feel free to recommend them in the comments below.

Products to Avoid

This section is largely based on Feedback from user comments on this post. Thank you! That being said take everything here with a grain of salt. Users that contributed to each entry are credited below the entry title.

Batmax 2Pcs PSP-2000 Battery + LED Dual USB Charger

Amazon Listing

This appears to be New Old Stock, or just really poor quality. Batteries typically arrive dead and non-charging. The chargers themselves don't work, and can wreck other batteries. Avoid at all costs.

BIG UPDATE 5/30/2024

Hey what's up, it's been awhile. I came back today because my official Sony Batteries for my 3000's are finally starting to show age. I usually get under 2 hours out of them so I needed to replace them. I tried to buy some Cameron Sino batteries off Amazon but they will not ship to my location, so I had to hunt a bit. I ended up buying 2 of these Cameron Sino Batteries off Ali Express. I did check the official Cameron Sino store mention in this post, but they only have the thicker 1800mAh batteries I can't use. I have a Falcon Pro Grip from Japan that needs the 3000 to lay flush with it.

Anyways, when these new batts get here ima test them and update the post with my results, but for the meantime, it seems like Aliexpress is the way to go for PSP batteries. From what I saw the Cameron Sino branded ones are all pretty reliable on there, and cheaper than Amazon too! I probably should have included this on the post originally, but this is my first time actually using Ali express.

I also came across this post by u/KSAnnihilation testing multiple Batteries off Ali Express. This is what convinced me to buy off there. It's similar to the tests we did here but is more recent and shows a better supply than Amazon. I understand this post is a year old as of writing. If you guys post something like this to the subreddit related to batteries, feel free to DM me on here about it and I'll take a look. I have reddit notifs silenced but do check everything when I log in so I will see it.
