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.
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.
