Hm, I thought nLoader was disabling the downgrade protection...
Ok, assuming you performed the installation how-to accurately, let's try bypassing nLoader :
- without releasing the keys, press and release the reset button on the back
- if the calculator didn't turn back on automatically, still without releasing the 3 keys, type , 2 times if necessary
What do you get on the screen ?
It's supposed to disable the downgrade protection but it doesn't reset BootD itself so if you EVER boot unpatched boot2 via esc+menu+- you are stuck
