I was receiving the 'Wifi error' with my Motorola Atrix. I needed to get inside the cell phone to access the tiny watch battery inside.
The tools worked great, I was easily able to get inside of my phone
Well, unfortunately the little watch battery is soldered inside the phone. I'm possibly going to try to desolder it and replace it with a new battery, especially since my insurance is $125 deductible for a replacement phone.
