About why PSP-1007 can't use software Downgrader :P

i buy a PSP-1007(Taiwan Ver) to find why this model can't use software Downgrader :P
i check the Hardware inside PSP-1007, it is same as other PSP

i use Hardware Downgrader make it to FW1.00
and try use FW1.50 EBOOT.PBP to update it but not success
the error same as software Downgrader :P

and then i use my FW1.00/1.50 Up/Downgrader program update it to FW1.50
that work :)

so PSP-1007 can't use software Downgrader, the problem is not on the PSP-1007 Hardware
the problem is it can't run FW1.50 update EBOOT.PBP :P

Great news! So you attached an external flash to be able to boot 1.00 or 1.50 on the 1007 before flashing the 1007 flash, right?
Do you have a picture (no detail, just global) of the setup?

no
just reprogram 1007 NandFlash

??

You started with 1007-F, fw 2.00, then change index.dat to make it look like 1.00. Ok. Then you cannot run your flash-code.

You have to boot the PSP to your 1.50 or 1.00 FW with the help of hardware, so you soldered 20 wires. Right?

no
this PSP come with 2.71
so i remove the MCP
program it
and resoldering it

So you can remove a +100 ball BGA chip, reball it and place it back !?
Whoa! :D :D :D

yes :P

do you clean and use new solder balls or just add solder paste or wire to the pads ?

remove MCP from PCB
reball MCP's BGA ball
reprogram MCP with a BGA socket
resoldering MCP direct to PCB

remove, reball, resoldering 137pin FBGA MCP Tools about USD1,000-
137pin FBGA socket about USD200-

Hi Ookm,
According what you said that the Hardware inside PSP-1007 is the same as others,
does that mean even PSP-1007 can also use the firmware for other region(ex: PSP-1000) ??

For example, if I change the nand flash of PSP-1007 with PSP-1000's, does that also works?

Thanks for your answer! I am really curious about the problem of failure to use the downgrader of PSP-1007,
because I am a Taiwanese. smile

By the way, I am woundering where is the bad block table in the nand flash?

>>Rintarou
FW & IPL no "region"
"region" in NAND Flash other Area
you can use other psp FW1.xx :)
you can't use other psp FW2.xx !!

& in NAND Flash No bad block table
just have a byte in spare area to defind it is "Invalid block"

The other area in the NAND Flash means the OTP block?

And the invalid byte is 517 of each page?

That make me more curious how PSP deal with the bad blocks(or I should say bad pages) if it was found. They should have a table for bad pages and map the valid pages for the FAT fs. Does it?

Thanks for your answer!

K5E5658HCM是没有"OTP block"的

yes

bad block table可能在RAM中
但不在 NAND Flash 中

>NO

That's a little strange since I checked the datasheet of K5E5658HCM-D060, the bottom of page 7 said that did include a OTP block. Did I miss something? Or I got the wrong datasheet?

Here is the link to the datasheet that I found.

>in NAND Flash No bad block table

If there is no bad block table in NAND Flash, how did PSP map the FAT sectors to the valid pages? It's so strange I think.
