This is very important. If you're running 3.71 M33, don't use, I repeat don't use USB function to flash either your flash0 or flash1 nand either in the recovery menu or xmb. You'll end up corrupting your nand partitions and even worst your idstorage.

The most important thing for all PSP Slim & Lite owners....BACKUP YOUR NAND FLASH. This can be done with Despertar_cementerio v3 or nandTool or upNand64 and keep it in a very safe place. You won't know when you'll need it.

There's a bug actually in 3.71 M33 corrupting the nand flash if you try to write to it via usb connection. Normally people who wanted to mod their themes will try to access the flash0 folder to copy the files there via usb. This bug is due to SONY's new protection scheme on the slims...hahahaha way to go SONY. rclxms.gif

Have you ever heard of nand or idstorage corruption on the old fat? The answer is no. The easiest way to backup your nand flash is by using a Pandora Battery and DA's DC v3. The backup will be named as nand-dump.bin into your MS. It will backup all 4096 blocks of the 64M nand flash.

I've already backup mine thumbup.gif ...how about you guys? Better safe than later crying here to get help.

Anyone of you who are getting the new slim, make sure before you ask the shop to update to 3.71 M33 CFW, backup the nand flash of 3.60 OFW first and then you copy the file into your thumbdrive or what ever external storage you have.

Hmm, tot, I tried to fit the normal fat battery into a slim, it's tight and the connector doesn't touch. Can't switch it on. Mind telling us how u did it? Or did u use original Sony 1800mAH Battery?
*
You must press it a bit hard to get it into the battery slot. I'm using SONY original 1800mAH Battery. Don't use third party/chaplang/cap chicken or clone batteries to make a Pandora Battery, same as the magic stick. Use original SONY MSPD.

howabout just changing the wall papers? is this also considered writing to flash?

My PSP Slim is ver 3.60 M33...

I guess i'll stay at this version for awhile... sweat.gif

currently looking for a nice Case to protect it.

would you guys recommend silicone or crystal?
*
Changing wallpaper is safe as it writes to flash1 from MSPD not via usb.

I'm using a silicone protector. Tried the crystal case but really don't like it seems it becomes a bit heavier...

1.how bout changing the theme on 3.71 M33? there is a theme setting where noobs like me can change the theme easily.
?

2. U mean transfering theme file to Flash 1 folder > VSH > theme will also brick the slims?

I'm having one slim but scare to touch the theme setting after my frens incident. Already into 3.71 M33 ...did not manage to get my  nand flash? am i still able to get it?

notworthy.gif

As long as you don't touch flash0falsh1 via usb you are safe. You still can make backup of your nand flash even though you already updated to 3.71 M33. The most important is to backup the nand flash while it is still in a working condition no matter on what FW you're on. I did mine on 3.71 M33-2 CFW.

I'm still new in this, it would be great if there is a step by step guide and *potential risk for doing a backup of nand flash.

i used to have a fat psp before but psp slims are too new for me. If i was not mistaken, theme file are store in flash1 ? or MSPD?
If MSPD, when i wanted to change theme, it will read from MSPD and copied into flash1? (i think my fren's psp brick because of this)

notworthy.gif
*
All the ptf themes are safe as they are offcially supported. The unsupported themes involving flashing some .prx / .rco files to the flash1/flash0 folders via usb. These themes are dangerous.

Your friend's psp brick because he flashed some files via usb to flash1...I don't believe it will brick with no reason..

Added on October 22, 2007, 4:02 pmIf you're too lazy to make Magic Stick and Pandora Battery, just go to any game shop that have expertise or have Pandora Battery and DC v3 and ask them to dump your nandflash and copy it from their mspd to your thumbdrive.

To be frank, i'm with my fren all the time. Starting from he bought the psp and went home with him. Did not even open the psp after sticking the hori protector. once home, just power on for the first time, and it so called bricked. Power led still on, but no display. Few seconds later, poer led went off.

It can be unbrick..the chances are like 70-30. try to use DC v3. I've unbrick one before but that guy bricked it again until the idstorage is damaged but still I managed to unbrick it but after that the slim lost it's wifi, umd and playing games and homebrews from MSPD capabilities. His psp slim can only play mp3 and mp4 files..

ok
1.  i am already on 3.71m33, not intending to flash etc (yet), so nothing to worry bout flashnand corrupt right?

wrong...nandflash corruption can occur randomly while using CFW. So better backup your nand.

QUOTE
2.  when i connect the usb cable, and go to usb connection, then connection established, i am accessing the memory stick folders right? this is nothing to do with the flash nand memory right?

Yes, you're accessing the MSPD not nand flash.

QUOTE
there are a few folders, i know ISO folder for backup games, music folder for my mp3, picture folder for my photos, video folder for mp4 videos (have not tried yet).  btw there is another video folder in ISO (what is this folder for?)
there are two more folders with subfolders
- MPROOT folder with subfolders but empty
- PSP folder with subfolders - theme folder (is this where u put any additional themes?), the rest of the subfolders i dun think need to be tinkered

any tips on the above is appreciated

btw i just installed Fifa08, and Virtua Tennis, and Worms - i think i am going to enjoy these titles.  MSG and Splinter Cell at this point too complicated on the PSP for me

no iso discussion her

QUOTE
ok last one, when on usb connection, the power led turns amber, this is the charging function??

Yes, it's charging...

yes...for psp slim if idstorage is corrupted then it's screwed as you must use the same psp slim nand backup. for phat you can use other psp fat nand to restore. psp slim is very vulnerable to brick. some sort like sony had put some virus...laugh.gif can't stress more, backup your psp slim nand.

erm.. from the googling results earlier, it seems sony has put some encryption on the nand flash0/1 vmad.gif

so, how to backup the flash0, while I don't have pandora's battery?
will the backup process cause the PSP to be bricked? sweat.gif

find someone that has one or you can buy one from datel. you won't brick your psp for backup the nandflash.

afaik, only can use one's own NAND/idstorage dump backup to recover from brick
in some cases, where the idstorage isn't corrupted, the PSP slim may be unbricked using other PSP's NAND dump hmm.gif

Yes.

QUOTE
btw, where the heck is the idstorage? flash0 or 1?
*
Here's your answer

QUOTE
Definition of Idstorage :

What is Idstorage ?

Consider Idstorage as a source of volatile data. The Idstorage is located in the IPL.

What is the IPL ?

The word IPL was invented by IBM to fulfill the needs of System/360. The IPL or Initial Program Load, is a hardware function (and not a program) , launched from the system itself. A predefined input/output command is initialised, launching the loading of a start-up program, without the need of a routine predefined bootstrap. The Idstorage is therefore located in the IPL, that is to say in the NAND of the PSP System.

And what is the NAND ?

Consider the NAND as a non volatile flash memory, which, via a system of injection and liberation tunneling, allows the reading and writing of this flash.

What does the Idstorage contain ?

The Idstorage contains a lot of information about the PSP : serial number, MAC address, PSP Region, UMD Reader Region, type of motherboard ... It's the Idstorage of the PSP that gives us all the available information about the PSP

I just post sumthing that those ppl who accidentally brick can seek for help.
cut n paste warrior as if i did not stated that i copy from other sources
seems like u have problem in accepting other ppl's views.

Great for u to put up a term "cut and paste warrior"  as if u r contributing sumthing better.

I will deleted the post earlier and i'm sure ur great Proven method will do lotsa help to the community!

Dun be such a j*rk. Everyone deserve to have their own view or ways of doing things. It is like u r the god, and ur answer is the best. That post was posted on 23 Nov, so i guessed it would be new to share. What a closed minded old psp fag!

Anyway, post will be deleted.

You yourself don't even have the guts to try and you want other people to be your guinea heh?...you're the fag here. Have I been bashing others posts here? Nope, only yours because your post can brick other people's psp. I have a choice not to share what I know (my post regarding how important to backup the nand and not to flash any file to flash0/flash1 via usb connection).
