What does nLeash do, exactly?
« on: January 22, 2011, 04:04:33 pm »
The topic title pretty much says it all. :P

Does it mess with some memory during bootup, to disable the code, or does it do something really weird?

Oh, you mean the coding part, I know what it does in practical terms, it changes the OS to an older one in Clickpads.

I have no idea of how ExtendeD did it, though.

I would love to see how it's done. It might have more possibilities than bypassing downgrades.

Of course, I can see why they would be reluctant to say how they did it. :P

It changes some values related to the downgrade protection in the NAND page. Ndless and Nleash are based on the same code injection method.

Ok. That would explain why you don't need ndless to use it :P

Wait, does this skip boot2 validation? or am I just getting my hopes up?
Offset 10-13: If nonzero, BOOT1 will attempt to run DIAGS by default; if zero, it will skip straight to BOOT2. (Either behavior can be overridden with the Esc+Menu+G key combination.)

Unfortunately It doesn't.

darn. If it did, we could use an ndless prog to make it always skip, and install a hacked boot2.

How hard would it be to bypass the current boot1? not overwrite, just change the boot sequence to auto-boot something else.
