Pokemon Black/White on R4i Gold Error Code -4

I have an R4i Gold (the one with the mario on the box), and when i try to load the rom patched with v4 and rudolphs, i get an error code -4. Ive tried putting Wood on it, that was supposedly compatible with the exact version i have, but when i boot the r4 i get a blank screen. can anyone help me out please?

If I'm not mistaken, Wood R4 only works for original R4 cards.
