Are these just bad block or what?

ps. when i use nandpro 2.0b it says
C:\Documents and Settings\Flasher\Skrivbord>NandPro.exe usb: -r512 nand1.bin
NandPro v2.0b by Tiros

Looking for usb interface device
FlashConfig:008A3020
256MB Nand Detected
Starting Block:0x000000
Ending Block:0x007FFF
Configured for Large Block Nand

why does it say 256 nand when it has a 512mb mu?

You don't need to dump the whole thing.

64MB is enough:

nandpro usb: -r64 nand.bin

Everything over 0x1000 is your onboard memory.

Strip your NAND dump down to 64 MB like this:

nandpro nand1.bin: -r64 nand164.bin

Use this for your ecc\RGH image.

ok. so as i understand it i only need 64mb of the nand to make a rgh nand?

i have read that i needed to dump the whole thing i order to do that?

and in jtag tool you can only choose 16, 256 and 512 jasper.
