Okie, I'll give this a whirl tonite. Have to copy all the folders inside the Memstick right, right ? After formatting, then copy everything back as it is, yes ?

Thanks for the guide.

ok.. my pleasure... sharing is caring right.. huhu..

Sure. The strangest thing is yesterday on firmware 3.71 m33-4 there's no lagging in Ridge Racer 2. It's only after firmware upgrade 3.80M33-4 that this problem start. Although I have been on FAT32 since I bought the PSP last week. Well, this is minor thing. let's focus on other stuff like SKYPE, MSN and Yahoo messenger on PSP.

actually.. if u buy ur psp with ur 4 gig memory.. some of seller already formated ur memory stick to FAT16.. so u didnt realize that ur memory already on that format.. BTW... that for everyone that faced the same prob.. actually, this problem also did happen to me.. then i figure out the solution from other forum...

i updated cos my 3.71
A)crashes when playing psx games
B)the skip sony logo doesnt work

wasted my time updating,cos the problem still persists

Okay, upon your request I tested my GTA Liberty City Stories, it did show some lagging, or it was actually like that? Only played once so didn't really notice its frame rate. Luckily I am not a fan of GTA series...

Somehow there are some slowdowns with MSes after the 3.80 update. The list is too long to be pasted here. I can't verify the list as I'm still on 3.71

I got that game as well, it doesn't make any differences, perhaps ur memory stick is using Fat32?

GTA is having the most impact on the new firmware, due to it's streaming nature from UMD/mspd.

Tested that game and there are no lag. I'm on 3.80 M33-4 and memory stick formatted to FAT32.

just try to format ur memory stick to FAT16 guys... n then just update ur result ok...

sorry for trouble anyone here.

i had read through the guide but still no idea how to upgrade to 3.80 M33.

can anyone give me a step by step guide?

and can answer some of my questions please.

1)i am using a 3.71 M33 firmware slim PSP, so should i use Pandora or DCv3? i heard that Pandora can't work well on slim.

2)so Pandora and DCv3 have same function as well?

3)i still need to create nand with other tool?

4)i heard that can't update(some sort of that) with the usb, or it will damage the idstorage or flash0 or flash1. can explain to me what is that?

5)What i have to take care or mention when i upgrading to 3.80 M33? i mean i have to use AC power, can't do it through usb and other as well?

*end*

please don't flame or ban me, because i have no idea how to upgrade to 3.80 M33.

thanks.

1) Pandora and DCv3 are only needed if you want to downgrade to older FWs. You can also use DCv3 to update to 3.80 but it is easier to use normal method

2) Pandora batt is required to make the PSP to read IPLs straight from MS and DCv3 have the software needed to flash the NAND

3) If you already have a NAND dump then you dont have to make a new one

4) Flashing via USB is buggy on 3.71 M33-2 but it has been fixed on 3.71 M33-4 but to be on the safe side, make sure you have a NAND dump for your slim. NAND on the PSP is where the firmware is stored. There are 4 NAND partitions: flash0, flash1, 2, 3, etc2.. flash0 stores the firmware and flash1 stores the setting of the PSP, flash2 for DRM licenses etc2. Somehow on slim, the flash0 is kinda encrypted and if the partition is damaged, you cant recover it fully unless you have a working NAND dump to restore it.

I use FAT16. I've already try some games....

Result:

1) Wipeout Pulse - Lag a bit....but not much.
2) Ridge Racer 2 - Lag every 3 seconds
3) GTA LCS - Lag almost everytime

Thank god nothing happen on MHF2

wow... we've got quite varies of result.. anybody else? coz.. so far.. for me.. its work fine.. but not yet tested with GTA.. high end game for psp ... can we said that?

Yes you can..

thanks for your explaination.

1)so if i wanna upgrade to 3.80 M33, i don't need the Pandora and DCv3?

2)i used to create a NAND before.but is that NAND contain for 4 partitions? or just for flash0?

3)so j have to create DCv3 to prevent my PSP bricked?

4)once i bricked my PSP, i can't swithc on my PSP? or cant go into XMB?

5)how to check my PSP is 3.70 M33 v2 pr v4? it only show 3.70 M33

sorry for the troublesome question again.

Now I'm feeling guilty already bringing up the lag for 3.80 firmware. But do not get paranoid people because I'm sure there will be fix and solution for this. Numerous users worldwide also has reporting the slight slow-down. So just wait a little bit.

1) Yes

2) The dump contains all flash0 1 2 3 partitions

3) DCv3 is needed to restrore bricks but the chance of bricking during fw upgrading from MS is quite negligible

4) You cant go into XMB and Recovery mode as well

5) if 3.70 M33 then it is most likely v1

The minimum requirement to upgrade to 3.80 M33 is 3.52 I think so you should be fine upgrading from your current FW. Make sure to upgrade to 3.80 M33-1 first and then only upgrade to M33-4

ok, final confirmation.

first, i have to download the 3.80 firmware, then download the M33-1 and M33-4.

then put the update and M33-1 in PSP/GAME/

since my firmware is 3.71 M33-1, is that possible i use usb to upgrage it to 3.80?

update not mean flashing?
