So let me get this straight, (this is confusing me a little)

To unlock XP2100+ processor

1: Fill in all L1 pits with non-conductive substance (apart from last one)

2: Close all L1 bridges including last one making sure to fill the pit with conductive ink

3: Thats it??

Or do you need to do the L10 swap as well?

Thanks
