well as some of you know, i went through a time where i acually cried to see that my psp slim had bricked because of messing with the flash.  now i learned my lesson and am gonna use cxmb to do my themes and back up my nand and flash0.

what you need
-Universal unbricker v3 battery
-hex editor, i used XVI32.
-your broken nand
-a working psp slim nand.

just a simple advice, before doing this, try to unbrick your psp with the Universal unbricker v3, when it reformat flash0 or something, and it hangs as in it doesnt do anything, then the nand is damage.

before we start anything, back up the broken and working NAND in a zip or special folder on your pc, that way if we mess up, we can still start over.

1. using the XVI32 open the broken nand dump (lets name it and call it idstore.bin)
2.  press CTRL and G and choose hexadecimal.  where the location with $ and some number replace the numbers with $108000
3.  after wards, go to the edit menu on the top left and click "delete from cursor" not "delete to cursor" and save it somewhere and name it idstore.bin.
4. using XVI32 again, open the working Nand and lets call it flash.bin.
5 like step two, press CTRL and G and choose hexadecimal and this time replace the $XXXXXX (x is a variable) with $107FFF.
6. go to the edit menu and this time click "delete to cursor" and save it as flash.bin.
7.  place the two file in you hardrive (local disk) under any name you want.
8. use Command prompt and type cd\the name you use for the file.
9. afterward type this,  copy /b idstore.bin+flash.bin nand-dump.bin    and it will merge the slim's original id with a new nand.
10. when done, rigth click the nand-dump.bin and check the size.  the size should be EXACTLY 69,206,016 KB.  if it is not, you may have done somethign wrong, good thing i told you to back up the broken nand and the working nand.
11.  place the nand-dump.bin file into the root of your memory stick and run DAV Universal unbricker V3.
12. when in the menu, press L, R, home and start to replace the nand.
13.  flash to original 3.71 fw   you may see the flash0 hang a bit, but it should change after like 5 secs.
14. when done flashing, then flash 3.71m33-2 firmware. 

the reason why i asked to flash to original firmware is that, when flashing directly to cfw, it can have certain problems. like my brightness went haywiring in xmb. when you press it rather than to shut off lcd.  if you still have some certain defects, use  chilly willy key cleaner

congrats, you have just unbricked your psp slim.

sorry for the delay in reply.  i hardly check this topic, anyways, no, it will not work if your idstorage is corrupt.  every psp slim is now design with its own idstorage in whcih if you have it corrupted, then its impossible to recover it.  im sorry for your loss.
