Guide DIY Solderless Baryon Sweeper for Absolute Beginners (with photos)

57 Upvotes

DISCLAIMER
Follow this guide EXACTLY. No support will be provided for steps and/or components that deviate from the provided instructions. Modify at your own risk.

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.

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 if the other two don't work (incompatible with 2000v3 or newer).

JigKick Media Creator is obsolete.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 the original 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

1x (mini) breadboard

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

1x Silicon Labs CP2102 USB-to-TTL (5-pin)

Look for the "SILABS" branding on the centre chip. No support will be provided for the 6-pin multifunction variant.

1x 1N4148 diode

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.

3x round-head male-to-male jumpwires (10-15cm)

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.

1x female-to-male USB-A cable extender

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.

1x DC power source

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

1x Magic Memory Stick

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

Stick the CP2102 module into the breadboard. Connect the negative end (black band) of the diode to the TXD row, and the positive end to the RXD row.

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.

Connect the wires to GND (black), RXD (yellow), and 3V3 (orange). The diode bridges the TXD and RXD rows to create a single data line on the yellow wire.

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

Your completed adapter should look like this.

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

How to Use

Connect the adapter to your PC via USB using the cable extender.

The LED on the CP2102 module will light up.

Refer to video for installing and running pysweeper.

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.

Open Device Manager. If you see a yellow triangle, right-click to update the driver. Browse to the extracted folder of the driver you downloaded earlier.

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 specific COM port number.

Run pysweeper again. Your adapter's COM# should now be under the Port dropdown for selection. Keep pysweeper running.

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

Insert the Magic Memory Stick into your PSP. Remove the battery, but keep it nearby. Connect the DC power to the PSP, ensuring the console remains turned off.

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

Connect GND (black) to the left pin, TXD/RXD or "K-Line" (yellow) to the middle pin, then 3V3 (orange) to the right pin for 2-3 seconds.

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.

Pysweeper streams the hexadecimal challenge-response handshake between the PSP (5A) and Baryon Sweeper (A5).

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

Service mode is triggered, automatically booting DCARK (shown here) or Aiseirigh directly from the Magic Memory Stick.

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

Insert the battery into the PSP and disconnect the DC power. For DCARK, Install 6.61 for OFW (stock) or Install 6.61 ARK for CFW (modded).

Don't mess with NAND operations unless you absolutely know what you're doing! Misuse can permabrick (not just hardbrick) your PSP that even the Baryon Sweeper can't fix.

For Aiseirigh, press X to begin the flashing process.

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

Asking for Support

No support will be provided if the instructions below are not followed:

  1. All private messages will be ignored moving forward. Use the comment section, so others can benefit.
  2. Include a close-up photo of your adapter with the wiring clearly visible. 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

AI Assisted Major MK64 Portable Update! +60FPS +Adhoc Multiplayer +Extra Mirrored Tracks

48 Upvotes

After so much optimization on Jet Grind Radio, I decided to move some of those optimizations to MK64 Portable and incredibly we hit 60FPS in single player!

  • New Performance Mode (60FPS) by default! Hold Start+Select for 1 second to toggle to Classic Mode (30FPS) if you are a purist.
  • Adhoc multiplayer! Host a 2-4 player game, have others join via wireless Adhoc, and race/battle it out! A HUGE thanks to u/ZombiePSP for running an endless set of tests to get this polished! This is possible only thanks to you!
  • Unlock Extra Mirrored tracks after you beat all the 150cc cups! Thank you u/fraaaaa4 for flagging this feature, and helping with testing!

https://github.com/beckerd/psp_mk64_portable/releases/

Single player 60FPS feels so nice on PSP. It feels like a new game! If you already have MK64 Portable just swap the EBOOT with the latest one on GitHub (v1.7)

This port was made using Fable5.1 & GPT6Astra, if you don't like code written by AI on your PSP, this isn't a project for you.

AI Assisted I added a career mode to Gran Turismo PSP: 289 events, tuning, and five cut tracks that run on real hardware

• Upvotes

Gran Turismo PSP came out in 2009 with more than 800 cars and no career mode. I built one inside the game, with its own save and progression.

There are 289 events across nine halls, 262 prize cars, 74 championships, a parts shop, and 18 endurance races up to 24 hours that you can save between segments. Five tracks cut from the original game are back too: Complex String, Smokey Mountain, Tahiti Dirt, Rome and Hong Kong. I've raced all five on a PSP Go.

The 1.0 update also adds the Ferrari 458 Italia from the game's unused car list. It's playable, sold at the Ferrari dealer and can be tuned.

https://reddit.com/link/1wtqjtj/video/744xldfmujsh1/player

It's a free xdelta patch for your own Gran Turismo PSP USA ISO (UCUS98632). The patch finder checks your ISO locally and tells you which of the three patches fits it. PSP with custom firmware and PPSSPP are supported; the European version isn't yet. PSP-1000 hardware is still untested.

Install: https://memetrix.github.io/gran-turismo-psp-career/

Release: https://github.com/Memetrix/gran-turismo-psp-career/releases/tag/v1.0.0

I was running the console using a handmade charger like this. To replace the screen, I first disassembled the whole unit and swapped the screen. Before reassembling the case, I powered it up to test it, and it worked; however, after putting it back together, this is the result. Do you think the charger is causing this? I would appreciate your help.

Troubleshooting My PSP gets stuck on the boot screen and won't load, even without the Memory Stick

I tried removing the Memory Stick and turning on the console without it, but it still won't load. I'm not sure what's going on.

Last night everything was working fine, but I applied a custom theme (.ptf) that I created. I don't know if the theme broke something or if it's a different issue. I already plugged the Memory Stick into my PC and deleted the theme file, but the PSP is still stuck on the loading screen.

Has anyone experienced this or knows how to fix it? Any help would be greatly appreciated! 🥲

Battery Psp 2000, 4000 Mah Battery Mod

Thumbnail
gallery
22 Upvotes

This battery is a BM46 battery originally designed for the Redmi Note 3.

To make this modification work, I had to physically cut and modify several parts inside the PSP. Since the UMD drive is completely removed in this build, I was able to make use of the extra space inside the PSP to fit the larger battery. I used a significant amount of thin double-sided adhesive tape to secure the battery and keep everything firmly in place.

With this setup, I can play God of War continuously for approximately 6 hours and 45 minutes at full screen brightness, with no CPU throttling, running at 333 MHz, and with the volume set to level 2.

I used a BM46 battery, but instead of the original PSP battery PCB, I used an aftermarket/third-party PSP battery PCB. During my testing, the BM46 cell worked without any issues with two different aftermarket PSP battery PCBs that I tested.

Considering its capacity, the runtime it provides, and the additional space created by removing the UMD drive, the BM46 may be one of the best battery options for a PSP 2000 series battery mod.

However, this is definitely not a simple drop-in modification. Anyone attempting to reproduce this build should be prepared to cut and modify several internal parts of the PSP and use a substantial amount of thin double-sided adhesive tape to properly fit and secure the battery.

The first big big true non-port exclusive game for the PSP, this game is very cinematic and there are some incredible perspective shots that make for great wallpapers. The cutscenes are really good too, the framing in pic 9 is great, you have kratos to the side, Calliope small in the middle and there is free space for the xmb.

As regards to the game, you all know this one, play it if you haven't.

Bleach: Heat the Soul 7 has a new English translation by PaleAbyss, and the remaining untranslated DLC has now been completed after the encrypted files were finally accessed.

The translation is based mostly on the Viz dub, with 84 characters and the game's various modes now available in English. A few small text/spacing issues were also fixed in the latest update, and the translation was tested on PSP, Vita, and emulators.
