Help! Black screen with white writing!

[Guysim]

Hey guys!

So I hacked my Psp slim-2000 twice already, and my psp was 5.50 Gen-D3 before this problem came up. The other day I decided to play it again but when I turned it on, a black screen came up with white writing saying:

Tachyon =0x00500000, Baryon=0x00243000
Nand size = 67108864
Model: PSP Slim

Press X to install 3.71 M33
Press O to install original 3.71
Press [] to dump the nand
Press L+R+start+home to restore nand dump phisically (dangerous!)


I'm pretty sure this screen comes up when you want to install CFW on a OFW right? But why is it coming up again! I dont remember putting any files that makes this pop up. All I did was turn it on! But I pressed X, hoping it would just go back to 3.71 M33 but after it said "Press x to Shutdown" I turn it back on and the screen is still there! But when I take out the memory stick and try to turn on the psp, it doesnt turn on at all! So has it something to do with the memory stick?

Can anybody help please! Ans sorry if this is in the wrong place but I really need help!

Um well it has 5.50 Gen-D3 but since I pressed X on the black screen which was meant to install 3.71 M33, I really cant tell what I have! Will I have to format the memory stick using my computer then?

Sounds like you're using a Pandora battery.

Take out the battery and unplug the AC adapter.

Leave the battery out, plug the AC adapter back in, put in the memory stick and power up your PSP.

Restore your battery to normal, or inject the Time Machine IPL to your memory stick.

Thank so much, but now when I turn it on it gets past the "Sony Entertainment" start-up logo and it freezes! I remeber this happening a few months ago when I was doing something with the psp but I forget how I fixed it. . . Has it got to do with the way that I pressed X on the black screen?
