GUIDE FOR INSTALLING 3.52M33-4 THEN 3.71M33-4 ,3.80M33-5 OR 3.90M33-2 WITH 1.50 KERNEL

OK I have a problem. Does anyone know how long it will take to update from 3.52 m33-4 to 3.90? Because Mine has been saying Unpacking.... done
Please wait...
For about 20 mins. What am I doing wrong? I have 100% battery and it's plugged in. I don't know if I'm on kernel 3.52 because that menu doesn't come up when I hold R while turning my PSP on.
Help me!
EDIT: An hour now :/

 

Retry, from what I have read and done myself, it should not take that long. If it happens again try remaking your stick and check that its an original and not a fake as some fakes can cause problems.

HTH

 

Do you have a UMD in the PSP? If not try it with one in, if that doesnt work try changing the settings in the recovery menu to NO UMD!

 

Tried it again and same problem. It isn't fake because it came with the PSP (giga pack). What's this about remaking my memory stick? Deleting everything?

 

I would format the MS and reinstall the 390M33-2 files and if it still doesnt work try going to 371M33-4 first?

Also is your MS big enough? 256mb minimum?

HTH

 

Hi guys... first of all.. ima complete noob at this.. I have absolutely no idea what to do... so please just point me in the right direction, and explain like you would to a 5yr old.

I have a new PSP Slim (it says 2004 on the box...incase thats important) the the System Software version is 3.72 ( i have no idea what OE, or M33 is)
this PSP was bought from Dubai duty free, if that helps also..

I tried to read through most of this topic, but i dont understand alot, and i really want to be able to play games from my memory card.
I noticed somewhere it said to see the BIOS version, I need to hold the right shoulder button while the PSP is turning on... I have tried this alot of times, but nothing happens.

please send a complete noob in the right direction.

 

Got it working.

 

What did you do?

 

Hi all,

This is my first post so please go easy on me

I recently upgrade to 3.90 m33-2 with 1.50 kernel after following all the instructions (I have an original 1.5 machine btw)

The problem I seem to have is that a lot of my "backups" don't seem to work but worse the whole menu system seems to be terribly slow which is also effecting playing the games as these too are running slow.

Anyone else experienced this? Have I done something wrong?

Thanking you in advance.

 

Hi Guys

I've just executed the 3.52 m33 from 1.50 and it seems to be stuck on "Writing 3.52 firmware...", the previous 3 actions completed okay though...what do I do? It's been stuck on this part for ~15 minutes

 

Yep
Many people who have upgraded their PSP to 3.90m33 are experiencing this problem
Install the "Fatmsmod" patch
Download it from HERE
You'll need to get the "fatmsmod.prx" from the 3.71 firmware
Also, see the "readme.txt" included in that download

Try putting the AC adapter in the PSP and execute the program

 

hey guys, it was stuck on writing 3.52 firmware for over an hour, but eventually it completed - i read on another forum that that stage took up to 4 hours to complete for some people. bear in mind, i didnt have my ac adapter plugged in at the time, and still didn t when it completed, so maybe having it plugged in makes it go faster?

im up to 3.90 m33-2 now, and i want to put a psx game on my psp, is there an easy way to do this?

thanks for any help!

 

Yeah
Download Simple popstation GUI from HERE
And also see, the "Guide on how to use popsloader" in my sig
Post you queries there as posting about PSX games here will be off-topic

 

hi installed everything as in guidee im running 3.40 oe-a when i execute the creator its says file 150.pbp couldnt be opend press x to exit then closes and goes back to normaal any ideas>?

 

hey i have a psp slim and i upgraded it to a 3.80 so can i play ps1 games...plz help me with this...

 

same as alzyrnr ^^^ except i just updated to 3.90, havent done anything with the 1.50...is that necessary to play ps1 games? where do i start? haha


I forgot...is it possible to copy ps1 discs that i already have onto my psp somehow?

thanks in advance

 

You may have not renamed the file properly or may be the "150.PBP" file must be wrong

Yeah you can
But you need a custom firmware for that
See my previous post in this thread

If you updated to 3.90 official firmware, then you'll have to update to a custom firmware to play PSX games on your PSP
(You can play PSX games on your current PSP is you have the PSX disc and a PS3)
The PSX game disc on your PSP ???
Do you mean the "EBOOT.PBP" ???
