Digital BW, The Print

I've just switched a cart, using my sk168 chip resetter
to reset the chip. Got a green light and everything on the
resetter, so I thought I was good to go.

However, it reads out at it's previous level. I've
tried resetting it again several times, same result.

Does this happen sometimes? That the resetter reports
success but the chip doesn't actually reset? Anyone
have tips to suggest before I break out the exacto 
knife and replace the chip?
