More PSPs can now be unbricked with new Baryon Sweeper keys
We talked a while ago about Baryon Sweeper, a series of tools and hardware schematics designed to unbrick later PSP models (which require more than the original pandora battery). Mimicking Sony’s official recovery tools, Baryon Sweeper allows to enter service mode and unbrick PSP 3000 models as well as pandora-incompatible versions of PSP 2000s.
Not all models are working with Baryon Sweeper though, in particular due to some missing encryption keys. PSP Hacker Davee has recovered some of these keys last week, unlocking unbrick options for PSP 3000 models 04g, 07g, 09g. At this point this means most PSPs can now be unbricked with the Baryon Sweeper tool. As I understand it, PSP Go
and PSP Street remain the only unsupported models, that cannot be unbricked today with this method (Update: PSP Street can actually be unbricked with this, only PSP Go remains).
How to unbrick a PSP With Baryon Sweeper
As a reminder, if you have a PSP1000, or one of the early PSP2000 models, you simply need a pandora battery and Despertar Del Cementerio to unbrick your console. Baryon Sweeper is a more advanced technique for newer PSP models (some PSP2000s and all PSP3000s) which use a different way to enter service mode.
The hardware and tools required to use Baryon Sweeper are described on Khubik2’s github, and remain the same as what we covered back in 2021 (video tutorial).
For the newly released support, you’ll want to grab pysweeper (and follow the steps of the readme), but replace keys.json with this new version (courtesy of Zecoxao) until khubik2 updates his repository.
Was this named after the “Baryon Sweep” from Season 6 Episode 18 of Star Trek The Next Generation?
It’s named after this because the syscon is codenamed “Baryon” by Sony themselves. So the author decided to create the tool with something allusive to that aspect.
Here is a list of codenames attributed by Sony to the PSP Components:
Tachyon (Theoretical Particle Faster than Light) <- Main PSP CPU
Baryon (Subatomic particle which contains an odd number of valence quarks) <- PSP System Controller
Kirk (Star Trek Character) <- CPU Coprocessor in charge of the crypto of the system
Spock (Star Trek Character) <- (UMD Chip?) Coprocessor in charge of the crypto of the UMD discs
UMD is Lepton)
The comments by Zecoxao and Yoti should be included in some wiki. I’ve always been wondering about the meaning behind those names and the legends have just provided the meaning, here in comments. What about pommel?
