Hi, I'm not clear wif one of the options during unbricking, which is dumping NAND.
Wat's this NAND, actually? Does it contains the firmware & the previous configuration itself? Is the NAND dump a whole image of how's the PSP works when the NAND is dumped?
Wat's the usage of this NAND? Is there any specific brick that requires NAND to unbrick? Can usual unbricking process replaces the process of restoring NAND?
According to the Despertar Del Cementerio Readme, the process of restoring NAND dump is dangerous. Is it bcoz it's a physical restore process? Wat does this mean? & this means it's not a logical 1? Wat does physical & logical means here?
Looks like my questions're a lot, but hope that u guys can kindly help me out, as I can't get sufficient information on this NAND for PSP. Wanna know how it helps in unbricking or any other usage. Thx in advance. Hope to hear from u guys very soon. ^^

From what I've heard it's a thing for restoring bricks. For example: backing up the 3.71 M33 nand would keep the firware info. If you use it onto another PSP is would install that firmware on it.
Thats why NANDs were created to unbrick a PSP. This NAND is not 100% safe. It has a 90% chance of killing your PSP XD (Permanent brick).
Correct me if i'm wrong :/
Note: Restoring NANDs on other PSPs can brick your alternate PSP. If you backup from one psp and restore on the same PSP it would be 99% safe.

Pretty much, it contains everything in the internal flash chips, including, but not limited to, firmware, settings, IDStorage, and the ps1 emulator by Sony.

The official usage of NAND is to make the PSP run, sort of. The unofficial use of the NAND is to restore bricks, and recover IDStorage, if our IDStorage becomes corrupted.
Quote:

If the IDStorage becomes corrupted, the PSP is bricked, only recoverable if the NAND of the bricked PSP is replaced. No other PSP's NAND works.
No, the usual unbricking process will not work in place of a NAND restore.

Yes, the danger is because it is a physical dump/restore. This means the PSP takes a full NAND backup, not leaving anything behind, not just taking needed files. A logical dump/restore would only use needed files. The danger is present because in the case of a botched restore, which can happen, the PSP will be bricked, and if you restore another PSP's NAND to your PSP, it will not turn on. So, restoring your own NAND is the only way to unbrick in either of those 2 cases.

I've googled, but I can't find sufficient information, that's why I'm posting here. Maybe there're relevant information for my questions, but it might takes up too much time for me to search for them. Bear wif my search skill. =p
I thought u can only restore the PSP NAND wif it's own NAND dump? Every PSP's NAND dump should be unique, I guess. Btw, wat'll be of permanent brick? Is this possible even wif Pandora Battery & Magic Memory Stick?

Wow, ur answer helps a lot. Thx. ^^
So, it exactly means it's a whole image of the PSP? If I restored the NAND, everything revert back to the previous state? If this is the case, can I use this method to unbrick PSP instead of normal unbricking method?
Wat's IDStorage, in details? Wat'll causes IDStorage to corrupt? Looks like it's gonna be a serious prob if u dun've the NAND dump when ur IDStorage corrupted. Wat should I do if this case happens?
Is NAND dumping dangerous as well?? Why'd taking every files, which is physical dump/restore is dangerous? How'd a botched restore happens?

Nand dumping is not dangerous. Its the restoration that is. Downgrading is much safer since it doesn't effect you PSP in any way.
Nand dumping is designed for unbricking not downgrading. There is a chance that it will fail though.
================================
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

So, NAND dumping itself has a chance to fail, as well as NAND restoration? Wat is the possibility?
Wat'd causes the IDStorage to corrupt?

Okay, according to the thread u showed me, it seems that I can choose physical or logical form to restore NAND. Is this true? If this is true, can I juz choose only to restore things that is not specific to the PSP?
Besides, the thread shows that unbricking by restoring NAND can be substituted by Universal Unbricker. Is this true as well?
Anyway, NAND dumping itself has a chance to fail? as well as NAND restoration? Wat is the possibility?
Wat'd causes the IDStorage to corrupt?

I dont think dumping it has a chance to corrupt, it just reads the nand n write to the memory card. You almost never do a nand restoration unless its the last thing u have to do. Im not sure how ID Storage Keys could get corrupt though. I know old downgraders rearrange them n change them to downgrade, but those are safe and can be fixed. I think another reason to use nand dumps is if your file system (Partition? is that the word?...2 tired...) get corrupted, not sure if theres another way though.

I dun really think dumping'd has any problem too, but according to LeadBaron, seems like dumping is dangerous as well. So, I wanna make sure whether it is or not.
File system corrupted? I thought this could be fixed by unbricker as well?
Anyway, anyone else, plz help to answer my unanswered questions above. ^^
