Tutorial created by DeathHades.
This tutorial will teach you to how to know the base firmware of your PS3 with a few steps and images.
The first thing you have to do is:
- A PS3.
- MinVerChk
Here I leave the MinVerChk - link: http://www.demonhades.org/foro/download/file.php?id=332
Well here I leave the steps.
1 - Enter the MinVerChk in the pen, as if it were an upgrade.
2 - Insert the stick into the PS3.
3 - Install the update from XMB (This will fail and display the Firmware Base).
Here I leave the photos.
