Is there a way to downgrade a PSP Slim from version 3.71 M33

Is there?

Are you asking whether you can flash any firmware below 3.71 on a slim? You don't technically "downgrade" slims You just use a pandora's battery to flash whatever firmware you want to it, I believe the latest is 3.90M33-3. But if the psp is already at custom firmware then you can flash any firmware you want to it without the need of a pandora's battery.

isnt the lowest cfw for a slim 3.60 or something like that?

Technically....But if u would like to go even further down, Time Machine is a GREAT alternative. Gets you down to 3.40 OEA

also, the latest firmware ace is 3.93 CFW by ketchupman over at QJ

I was referring to "official" releases by M33.
I don't see why you would want to use 3.40OE-A though on a slim w/ time machine .

for 1.50 Kernal homebrew support. The whole reason why DAX made it for the Slim in the first place. In ur face.

Meh who needs 1.50 kernal support. J/k, You could always just use a later firmware such as 3.52M33. Banned for giving a lame reason and saying "in your face" nublet.

banned for saying a slim can have 3.52 M33.For all those noobz reading...Slims can NOT have 3.52 M33 (or in that case OFW either) Whos the noob now ACE?

My slim has 5.52M33 with time machine noob
Stop spamming already.

My friends Slim has 3.52M33 also.

And yeah, all you'd need to do (if you don't like 3.71M33) is to go to a higher CFW. If you actually wont to go lower than 3.71 you'd have to pandora the slim again to flash another firmware (I think)

Ace, I only just noticed that you've got the "PSPbrew staff photo" under the picture of the monkey xD

How does a Slim have 3.52 M33? I was almost sure that with time machine u could only choose 1.50, 3.40 OEA, or 3.40 OEA mixed with 3.60 for slim.....

Ohh, yeah I did mean flashing X-P

But thanks to you guys, I was able to get it version 3.5M33
