Great guide but make sure you REMOVE THE AUX SD CARD FIRST if installed or you will break the card and or card slot.

Other than that, no problems. I got the io board for $26 and I put it in for free.

I need an io board for cheap… I might have to make a guide on how to attempt to repair io card without proper tools and a filed down soldering iron tip

Thank you this was helpful. I think I fixed my screen flickers the LCD ribbon is under the battery and the ribbon from the volume board on the right I think that’s related to the screen rotation lock. Those needed to be flipped up and reseated. Thanks
