6.20 TN-D Permanent Patch

A patch is available to make 6.20 TN-D permanent on your PSP. While it doesn’t completely install a custom firmware on your PSP, it does make things a whole lot easier by allowing you to boot directly into 6.20 TN-D instead of having to manually re-run the signed homebrew app each time you turn on your PSP.

Of course, there are risks with this as you’ll be writing directly into flash0 so again there’s a slight chance of bricking. However, the 6.20 TN-D permanent patch is relatively safe as the plugin does allow you to test it first before actually installing it. If the test fails, don’t proceed with the installation.

Run 6.20TN-D Permanent Patch again and select the uninstall option

Troubleshooting

Important Note: If you experience any problems with the permanent patch, there are two ways for you to recover:

-while starting the PSP hold R1, this will disable all plugins and set the settings to default.
-while starting the PSP hold o + x + SELECT + START – this will completely uninstall the 6.20 TN-D permanent patch for your PSP.

I was actually holding out on posting the permanent patch as it is quite risky. The upside to having the permanent patch installed however is that it opens up new possibilities for homebrew development like the recovery menu. Having development on top of the permanent patch simply means it’s quite stable and safe enough for the common.
