Did it work perfectly before you updated? If it did, then try restoring default settings (I think it's Settings - System Settings - Restore Default Settings), then try.

(This will erase your username, internet configuration, background, time and date, and a few other things, but your saved data, pictures, music etc will still be there.)

i did that, but i still dosent work.
(another question: is it the "R" button u gonna press on startupp to get in to the recovery menu?)

Yep, you press the R button to get into Recovery. And did you experience anything like this before you upgraded? Plus, did you do anything that might have triggered it? Even anything you think didn't cause it?

okey, now i'm pissed... can't get in to recovery neither...
no never, it worked perfect before. well, i haven't been useing it for about 2 month. i haven't used any homebrew i have only played locoroco (Original UMD game) so i can't think of anything. >.<

Are you sure you're holding R from the time you flick the switch? If you really can't get into Recovery, you should probably try downgrading. What was the latest firmware that worked for you?

3.71 m33. but what could have gone so wrong?

OK, so you've got Recovery. That's OK. But it might be worth checking to see if you can connect properly with any other devices that have WiFi (your laptop, phone, whatever you've got). If you can't get on with any other devices, it's the router's problem, not your PSP's.

But if it is your PSP's problem, I don't know what's gone wrong. But I have experienced a number of problems with upgrading custom firmwares - including a very strange one with my white PSP, that occurred when I upgraded it from 3.03 OE-C. It wouldn't turn on at all - apart from Recovery mode. I tried reinstalling the custom firmware - nothing. What fixed it was going back to 3.03 OE-C. Nothing really had changed, I just made a perfectly legit update that worked fine for thousands of other users. The next update, however, worked fine - it was just one update that didn't work.

So what I've learned is that if you come across a problem that occurs after updating, and makes no sense at all, the best thing to do is go back to the one that worked, and wait for another major update to come along. So, in your case, I'd advise going back to 3.71 M33 and staying there.

But before that, just check the access point with another device with WiFi. Who knows, it might not be anything to do with your PSP anyway.

okey, i will try with downgrading^^ my laptop works fine with the router, so it can't be that. thx for the help DorkDork^^

did you check to see if your wep/wpa keys were still saved. whenever i have updated cfw or factory resetted (sp); the keys did not save, nor did the access point info. i had to reset-up all that info. did you scan for an access point when you tried to connect to the internet, because if you did you need to re-enter your wep/wpa key.
