Where you soldered before - capacitor sp1 and sp2. Also check if you haven't scratched off any of traces around cpu shield when you were removing it.Where exactly to check?
At my V2 mod capacitors multi-meter was showing 16 and 20 ohms. Also when you were removing nand, did shield fell off? If yes, check if it's flat and not having any contact with components underneath it.
