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 (http://hackspire.unsads.com/wiki/index.php/Memory_layout). 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.
