help on firmware

[psp15]

hey guys what do you think is the best firmware to upgrade to and why?
mines 2.71

1.5, 2.71SE or 3.02OE-A, the latter 2 being custom (non-official) firmwares.
If your psp is currently 2.80 or below I wouldn't update as you will loose all access to homebrew.

Yes, I would try and get hold of the 2.71 downgrader and get your PSP back down to version 1.50 to make full use of HomeBrew.

For me 1.5 or 2.71 firmware would be great because you can still use to homebrew..

[Lanacane]

Just keep it at 2.71 mine is 3.03 I cant use homebrew now it sucks I wish they have a downgrader so your lucky

[haw]

Would anyone happen to have any information about when a downgrader for 3.03 firmware would be available? Didn't mean to upgrade and well I'm stuck now.

haw: No idea, its not somthing you can really predict. Most of the current downgraders work by gaining full access to the psp's hardware through exploits (taking advantage of security flaws) in the psp's picture viewer.

When a new downgrader comes out, sony patch the flaw it used to work and release a new firmware update. This means people working on downgraders have to look for a new way to gain access and force the unit to accept a lower firmware.

The most recent flaw that lead to the 2.71/2.80 downgraders was actually discovered by someone on a pc looking through a library (collection of code) to do with viewing .gif images, this was then applied to the psp's photo viewer and found to work.
So you can see its not really a 'it'll take X number of weeks to get it working' but more of a 'hopefully one day soon some smart guy will find a new exploit that is present in the latest firmware'.

The best and really only thing you can do is be patient and not update any further.
