PSP Custom Firmware 3.90 M33 is out together with the 1.50 Kernel Add-on
Sony has just released a few days ago, the latest official firmware for the PSP. It’s 3.90 and I think it mostly benefits the PSP Slim users. Phat PSP users like me won’t really benefit anything from it. The new firmware has the Skype application now. Skype enables you to call using your computer to any phone around the world. Now you can call your friends from PSP to computer or PSP to PSP or PSP to phone via Skype. But you would need to buy the PSP mic and headset though. But that’s not great news. The great news is Dark Alex has done it again. You can go to his website now and download the new 3.90 M33 custom firmware and install it on your PSP.
But wait, there’s more! Dark Alex has also released the 1.50 Kernel for the 3.90 M33. You can grab it from his website too. If you have problems installing the latest custom firmware, do not worry because I will write a guide as soon as i have installed the latest update on my PSP.
I also heard that you can install 1.50 kernel on the slim now. Don’t get too excited because I’ll be writing a guide on that too.

if a psp phat with a 3.80 M33-5 CFW and 1.5 kernel is already installed, if i update to 3.90 M33 CFW, should I reinstall the 1.5 kernel with the new guide or there’s no need to it?
February 3rd, 2008 at 1:57 pm
@De Facto: yes. You’ll have to reinstall a fresh 1.5 kernel on the 3.90 custom firmware.

you’ll be getting a slim psp does that mean you’ll gonna stop writing updates steps on a fat one?
February 4th, 2008 at 3:22 pm
@bendorf: of course not. If I have both the fat and slim then I could write more updates.
February 4th, 2008 at 4:09 pm
well, is it already good to be on 3.90?
my silver slim is at 3.80 m33-5.
February 4th, 2008 at 5:24 pm
While installing the 3.90 CFW…I bypassed the battery option. When the update started and reached 25 %…the battery died…So my PSP is bricked. Any suggestions how to fix it?
February 4th, 2008 at 9:00 pm
is it true that the 1.50 kernel for phat can already be installed on 3.90 slim psp?
February 4th, 2008 at 10:47 pm
@Shady: You should have plugged in your PSP to an AC Adapter. That’s what you get for bein too excited. Fix it with Pandora’s battery.
@Codename V: Yes it’s true.

@looneytunez2 and @em2x: If you are using custom firmware, change your region settings on the recovery mode to America. It’s only available on the Slim.
@rhythm07: I think you don’t need to but to be safe just revert your flash files back please.
