M33 Firmwares for noobs

[pumpee1980]

Some Noob help if possible. I have installed custom firmware onto 2 fat PSPs. A friend has asked me to do the same on a PSP Slim. Do I need a Pandora battery to do this or can I just downgrade then up grade to custom firmware? It is currently running 3.71.

Many thanks

You need a pandora battery then place dc7 on it and it will install custom firmware 4.01 m33-2 on your slim psp. Then do this in quotes

Download the files below and extract Part1. Part2 will automatically extract making 1 ONE_STOP_UPDATE folder.

Drag the PSP and 1.50.PBP to the root of your PSP Memory Stick. Using a transfer cable from your pc to your PSP... If it asks to overwrite choose YES TO ALL.


Once copied goto the game icon select mem card and then find the MUX2.0 icon and click on it. For you particular case start with update 6 and use the arrow keys on the psp to select update 6 then hit the X button.The Psp will take a few moments and the functions of the arrow keys will lock when they unlock choose exit and exit the mux area. Now goto the game icon memory card section of your psp and select your update 4.01

Follow this procedure all the way to update 9 and you will be at 5.00 M33-3

Also since you are running a fat PSP run the 1.5 kernnel addon that corresponds to your firmware so you would run the 1.5 kernnel addon for 5.00 when finished.

When complete just reformat your memeory stick and your good to go.

Hi,

I have a PSP fat running 3.52 firmware. To upgrade to custom firmware I believe I need to down grade to 1.5 before upgrading to M33 firmware. Is this correct? I have found the link reference upgrading and downgrading however I can not see the file for downgrading from 3.52 to 1.5. Is there a way to downgrade from 3.52 to 1.5? I have a copy of GTA with 2.0 firmware if that helps. I have used this method before to downgrade to 1.5 but that PSP was running lower firmware.

Any help would be appreciated.

Thanks

I have installed a few PSP here and there, never really had any problems. But today i did my friends PSP for him, was running 3.40 OE-A.

I used Despertar Cementerio 7 to get it to 4.01 m33-2, then installed 5.00 m33, then decided to look online and found updates available on PSP-HACKS and installed 5.00 m33-4 (and 1.50 kernal).

Now all works fine, except the WIFI will not work??? Its saying the WIFI Switch is turned off on my PSP console no-matter if the switch is set to ON or OFF??? I tried googling it, and checked revovery/xmb settings and still nothing. Any ideas?

Cheers, Roger

either by using a hacked psp to softmod it, or open it up and lift a pin/leg on a special chip.

i opened the battery and lifted the pin , then closed it back and tryed to turn it on but it wouldn't turn on

[BCman]

if u insert the battery, and it is hardmodded correctly, it will automaticly turn the psp on.
if it doesnt then u did something wrong.

[sai32]

do i have to soder it because i just lifted the pin up

[Demonchild]

No you don't. As long as the pin is lifted, your battery will fall into Service Mode.

The only time you need to solder the pin back is when you want it to work as a normal battery again.

what if the power LED light turns green when the battery is in but it doesn't turn on , does that mean anything ?
