PSP 3.03 Downgrader !


Recommended Posts

After much work over the past few days, we finally succeeded - we have an easy-to-use downgrader for v3.03 PSPs!

Some ground-rules:

This downgrader is for v3.03 firmware only. But if you have v2.81 - v3.02, no problem - you can just upgrade to v3.03 to use the downgrader.

You need a copy of the unpatched GTA:Liberty City Stories UMD. No ISOs, no patched UMDs, not Vice City Stories. See here for some info on how to check if your version is patched. The most reliable way : the unpatched disks have the v2.0 firmware update on them.

This downgrader is intended to enable homebrew. Homebrew is NOT the same as piracy. Don't be a thieving loser - buy the games you play.

The downgrader will work on all current PSP hardware (TA-079 - TA-086). Patching of TA-082+ is automatic in the downgrader.

You downgrade at your own risk. There is always a chance of bricking, although we have done everything we can think of to make this process safe.

Yea, but its a HUGE step for these guys. I was hoping to get this tonight before work tomorrow.

I went through the whole 'hello world' procedure to make sure i had the old gta umd, and everything went smoothly.

Im going to go ahead and upgrade to 3.03 now and go though this process now. (crosses fingers)

Is it easy to get hold of a unpatched GTA?

I'm considering getting a PSP now... :whistle:

I just got my PSP for x-mas and didn't need GTA. Mine came with 2.6 so I upgraded 2.71 then used the TA downgrader to 1.5.

I just updated from 3.03OEB to 3.03OEC yesterday. You only need GTA if your firmware is >2.71

I see.

I was under the impression that all PSPs that can be bought now are 3.03.

Oh of course not. I would imagine most PSP's you would find arn't even >3.00 because stores still are getting rid of their older psps. Trust me, it would be very easy to find one under 3.00 if your looking for one :D.

It only took about 1 or 2 minutes for me. You are referring to the update maker right? The update maker extracts files from 1.50 and 3.03 firmware files then creates a dxar file which you move into the flasher folder. The update maker doesn't affect the PSP's flash at all so it's fine to power off - if this is definitely the point you're at.

excellent i powered off and trying the process again, now it appears to be stuck on the 1.50 firmware subset...

any chance of you or someone else sending me the dxar file it's sposed to create?

I heard about the 3.03 downgrader a few days ago, and I was really excited, until I read that you needed a copy of GTA. So to hell with it, I upgraded to 3.10, and I'm just gonna wait for that downgrader. And here's hoping that one doesn't require another UMD.

You should've just left it at 3.03. At least then you would've had the option of waiting to obtain a copy of GTA or someone to release another downgrader that didn't require it. 3.10 doesn't offer anything useful anyway :)

thank you phemo for the file, you may kill the ftp :)

thank you phemo for the file, you may kill the ftp :)

    • AltSendme 0.4.1 by Razvan Serea AltSendme is a minimal, cross-platform application designed for fast, secure, and private peer-to-peer file transfers. It allows users to send files or entire directories directly between devices without relying on cloud servers, accounts, or any personal information. Everything is encrypted end-to-end using modern protocols like QUIC and TLS 1.3, ensuring both strong security and low-latency performance. Transfers are verified with BLAKE3 for data integrity, and interrupted downloads automatically resume, making the experience reliable even on unstable connections. You can transfer anything—images, videos, documents, and more. Integrity checks are performed on both ends, so your files are automatically verified for correctness during both sending and receiving. AltSendme works seamlessly across local networks or long-distance links, capable of saturating multi-gigabit connections for extremely fast delivery. With built-in NAT traversal and encrypted relay fallback, it connects devices almost anywhere. The app integrates with the Sendme CLI and will soon support mobile and web platforms. Fully free and open-source, AltSendme offers a lightweight, privacy-first alternative to traditional cloud-based services, removing size limits, upload costs, and unnecessary data exposure. AltSendme 0.4.1 changelog: Release Highlights Self-hosted relays: Run your own iroh relay so transfers don't rely on public infrastructure. Includes a full deployment template in deploy/relay/ with Docker Compose for a VPS and configuration examples for production use. Fly.io support: One-click deploy template for Fly.io, including a quick-start config (fly.dev.toml) for testing without a custom domain, plus production setup with Let's Encrypt and your own hostname. Relay settings UI: New Settings → Network panel to choose how AltSendme connects: automatic public relays, custom self-hosted URLs (with optional auth token), or disabled. Test connections, verify latency, and see live relay status in the footer. Disable relays: Turn off relay servers entirely when you only need same-network transfers (e.g. LAN). Direct connections only. No relay hop required when devices can reach each other. Android graduates from beta: Android is now part of the regular release cycle alongside desktop. APKs ship with each version (universal, arm64, and armv7). Other improvements Private relay access control via shared auth token Relay fallback notifications when a custom relay is unreachable Broadcast mode toggle in sharing settings Android release build fixes (split-per-ABI APKs, universal APK preservation) UI polish: mobile safe-area insets, dropzone layout, transfer progress animation Bug fixes for minification-related serialization issues and system tray icon loading What's Changed feat(relay): add relay status functionality and settings UI (a120cdf) feat(relay): implement custom relay server configuration and verification (51276c7) feat(relay): add configuration for private relay access and enhance observability features (48fbabf) feat(relay): enhance relay URL validation, display connection status (d4fffa0) feat(relay): add RelayChangeGuard component and enhance relay-related translations (16ba514) feat(broadcast): add toggle setting for broadcast mode in sharing UI (ca6d977) fix(relay): correct QUIC discovery port, pin image, templatize fly.dev (52a2ba5) fix: More broken serialization due to minification (67491a9) fix(android): preserve true universal APK across per-ABI builds (e9f256f) fix(ui): conditional safe-area insets padding on mobile (1182f0e) refactor(transfer): CircularRing component animation fix (944572b) chore(android): drop x86 and x86_64 release APKs, keep universal+arm64+armv7 (34ada0b) Download: AltSendme 0.4.1 | ARM64 | ~9.0 MB (Open Source) Download: AltSendme for MacOS | Android Links: AltSendme Home Page | GitHub | Screenshot Get alerted to all of our Software updates on Twitter at @NeowinSoftware
    • You are mostly right about the ephemeral nature of it. As I mention in the article, if you dont add a second device or take a backup of your account before uninstalling it, then yes you will lose access to your account. That said, in terms of actual user experience when you sync multiple devices your message history carries across and there's also a Saved Messages chat like there is on Telegram to send messages and attachments between your installs. But yh, what you point out are correct and its not trying to emulate Messenger or Telegram.
    • OK so SearXNG is a meta search engine that you can install locally or use via a public instance. It scrapes other search engines which you choose and then sorts the results. Not as complicated as multiple relays
