How do I no if I need to use a fibreglass pen to get a good connection with the pogopins, and d0 pin? Can I use a multimetre? should i get continuity to earth on each connection and d0 pin? because i am having trouble getting the modchip to be detected so this is the only thing i can think is the problem!

I used an exacto knife to "prepare" the d0 point. I really didnt see anything happening but I scraped at it for a few minutes. I then installed my xectuter 2.3b lite+ (Solderless). Lined it up and it worked fine. Some people say you dont even have to prepare the d0 point. I would just keep trying to get it aligned. That took me like 20 minutes.
