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
- USB (FAT32 / PS3 Readable)
Here I leave the MinVerChk - link:
You must login or register to view this content.
1 - Copy the MinVerChk to the USB Drive, as if it were an upgrade.
2 - Insert the USB stick into the PS3.
3 - Install the Update from XMB (This will fail and Give An Error Displaying the Firmware Base{The Lowest Your Firmware Can Be Downgraded To}).
