2.81 umd on se-c?

I have been looking around trying to work out how to make 2.81 umds work on 2.71 se-c but It's all very confusing. Could someone direct me to an installer or guide? Thanks in advance.

I have heard of this problem before

Well heres what i did.

First I instaled SEC on my psp.
Then I Formatted my memory stick.
I used the same app again to replace the recovery folder.
Then i used this to put devhook 0.50 on my psp.
Then I just followed the directions on dumping my psar and using the bat and i was set :D

I have installed devhook and used psardumper but I am not sure what to do next

If you have Devhook working at 2.81 or 2.82, run it, your PSP will reboot, and it will think you are running 2.82. Then just pop in your 2.81 UMD and press X

You could always forget about DevHook 0.50 and use the DevHook 0.46 Hybrid. It plays upto 3.01 UMD's.

Yes it will. But for some odd reason it won't seem to launch the new star wars game.
