Updating psp firmware 4 21 to m33

This is perfectly OK, because the M33 Creator is doing it’s work in the background. Look into the applications menu again, and you should see another application called the “M33 Upgrade 3.52”.After you have run it, you will be shown a disclaimer and asked to press the X key to confirm.some are simple, and some are complicated so I will post here a simplified direction in updating custom firmware: : A failed update may result to Crashing your PSP system making it bricked.

Before installing, I searched for instructions available from the net.

They work very hard on this firmware, and they make no profit from it.

So I highly suggest that you visit their page, and make a donation so the M33 team can continue hacking the PSP.

Make sure to check back often for updates on M33 firmwares, and all-in-one packages!

And if you come across any problems with this tutorial, I suggest you visit the ur PSP forums and post your query there.
