[violentj1]

just got what i believe is a jtagable 512mb jasper-dash 7371-

i have had a look around and seen a few mentioning it but i just wondered which is the best guide to use for lpt
read/writing 512mb

The commands are the same, replace the 16 with 512 and you should be good. When you read the nand, make sure your flashconfig is right - should be 00AA3020.

The config location is different though, I think it is EF7 2. I recommend you to read the big nand XBR release thread to make sure.

this is why i had to ask that thread states replace r16 with r512,ive read guides that state r70 and various posts that claim its just the firs 3 blocks needed

ive already done my falcon,but this is starting to blag my head

its not my box its my mates and i dont wanna go fooking it up

and wouldnt dumping 512 take like hours upon hours?
christ the things you do for friends

Using LPT probably close to 16 hours to dump 512.

It took me almost a whole week to dump my original nand 6 times to verify all's good.

You SHOULD read the entire 512 to make sure you have a complete NAND in case you need to recover.

If I were you and doing this for a friend, I'd be extra cautious and dump the entire nand a few times.

Good luck.

you only need the first 64mb (-r64). This is the file system, anything after that is used as memory for storage.

If you dump the first 64, then you will notice it is the exact same size as the XBR image (roughly 67mb)

First 3 blocks are only needed to check the CB version to see if the fuses are blown. On jaspers this is needed to check because even though it has an exploitable dash (7363/7371) the CB could have been updated. So when people are talking about the first 3 blocks, this is what they are talking about.
