Thank you! I really hope this is the last time I have to trim the board, I'll practice dremeling on cardboard or a pcbLooks good. I might give yourself a little more wiggle room on that line parallel to the NAND, just in case you need more room to sand, but you left more than enough room around everything else. That's ok though. Good luck with this trim!
You can also practice along the parts of the motherboard that you don't care about. This will give you better practice, because cutting through a motherboard is very different than cardboard.
Should my dremel at the speed at 4 or 6?Or a dead Wii.
thanks for the help!
it will make your life much easier.
will do! I can still turn it on right? And what if it doesn't work? Will I be fine?Make sure you relocate the u10 and make sure everything is working before you trim.
what I meant was if I relocate it and power it on if I did it properly will it work?
if you do this, it will make it much easier to figure out what's wrong if your Wii doesn't boot up after you trim it. On another note, what I do when I trim is cut a little bit outside the trim line with the dremel cutter, and then get closer to the line with the dremel sanding wheel. Sometimes the cutter can be kinda hard to control. Be sure to leave room to sand with the sand paper though. Good luck!! You can do it man!! Take your time and think it all through.
