Hello Fellas,

My Note 2 has a busted wifi, bluetooth, and gps (it attempts to turn on the wifi but never actually does). I suspect it is a hardware issue since I have factory reset my phone (didn't fix the problem) and even updated the drivers on my phone. It seem to be a common problem with this phone. The only solution I have found online is to wack the back of my phone until the signal is fixed. This is a good temporary fix but the problem returns after a day or two (sometimes within hours). I was hoping I could maybe replace the wireless signal piece of hardware and finally fix my phone. Could someone point out the correct hardware piece, please. (btw: I do receive regular phone calls , text , and 4g data)

Thank you, Kevin

Great job Sam!

Just one question: What are the steps after Step 21?

It seems to end suddenly...

Secondly, where can I but a Note 2 motherboard?

Hey Fuz!

The guide ends at step 21, because the camera is the last thing to come off of the old motherboard, it will then be the first thing to go back on the replacement motherboard. All you have to do is follow the steps in reverse to reassemble the device. Unfortunately we don't sell the Note II motherboard right now, but a quick search on eBay brings up quite a few options!
