Hello:

After JTAGing a lot of consoles got one Slim with a bad block on position 003 remapped to 3ff, my problem is that i need to put the glitch.ecc on the first 50blocks, how can i remap that file? Should I build my *.ecc with the original nand or with the mapped one? Already tried

nandpro glitch.ecc: -r16 3ff.bin 003 1
nandpro usb: +w16 glitch.ecc
nandpro usb +w16 3ff.bin 3ff 1

but without luck

Can anyone help? Thnx a lot.

if 0x003 is still readable, do this:

nandpro usb: +w16 eccimage.ecc

then

nandpro usb: -r16 bb1.bin 003 1
nandpro usb: -w16 bb1.bin 3ff

then

nandpro usb: -e16 003 1

Already did that but no go .... cannot read it or erase it... If i put original nand console boots fine...my doubt is if i neet to use +r/-r or -w/+w since im manipulating an *.ecc

Since I cannot read the 003 position I have to read from the *.ecc and put that into 3ff right?

So

Nandpro eccimage.ecc: +r16 bb1.bin 003 1

Then

Nandpro USB: +w16 eccimage.ecc

And

Nandpro USB: +w16 bb1.bin 3FF

Let me know if this works.

It didn't work, already tried to remap original nand like this

nandpro nandoriginal.bin: -r16 003.bin 003 1
nandpro nandoriginal.bin: -w16 003.bin 3FF 1

and create ECC from the remapped one and still no go...ned to try to remap the original nand like above and do:


Nandpro eccimage.ecc: +r16 bb1.bin 003 1

Then

Nandpro USB: +w16 eccimage.ecc

And

Nandpro USB: +w16 bb1.bin 3FF

like you said but to be honest it doesn't make any sense will probably not work... i can tell by this that if you have bad blocks in the first 50 of your nand its impossible to glitch it...

look at the plus / minus symbols - they're important.

I've copy pasted yours... but still no go... already done a lot of searching on other forums and can't find anything...looks like nobody has badblocks on the first 50 blocks lol

ok - try this:

your original nand dump is nanddump.bin. make a copy of it to nand-test.bin
your ecc file is eccimage.ecc

1. Flash ecc image to NAND:

nandpro usb: +w16 eccimage.ecc

2. Inject ecc to nand-test.bin:

nandpro nand-test.bin: +w16 eccimage.ecc

3. Extract block 003 from nand-test.bin:

nandpro nand-test.bin: -r16 003.bin 003 1

4. write to your NAND at 3FF:

nandpro usb: -w16 003.bin 3FF


Follow the plus and minus values carefully.
