are you using a genuine nintendo wiimote?
when you are already going to update something i would go for the softmod any wii guide by mauifrog, you'll get a full up to date ios and cios set.
normally previous installations does not interfer on resoftmodding, in your case you may want to delete hbc before starting over, as you are on 4.0 you can use bannerbomb to reinstall hbc and bootmiis latest version too
(guide also linked below)
no other clue maybe someone else jumps in
good luck from my side
