update**
finally did this mod. you do not need to remove the 2 screws under the label. comes apart just from the screws in view. I followed the wire leads on the videos and noticed, when i charged the device...it thinks that im charging thru the computer and gives me the option of "mass storage", charge, and tether.

any thoughts?

(sorry for late answer, just stumbled upon this this thread)

The phone correctly thinks that it is being charged through computer, because the data pins of the USB port are not shorted together. Have a look at the USB pinout (type Micro-B) Universal Serial Bus - Wikipedia, the free encyclopedia. The phone's microUSB port looks like this with 5 pins \54321/ You have connected TouchStone back to pin1 (positive/+5V) and pin5 (ground/negative). When the phone receives electric current through these pins, it looks if data pins (pin2 and pin3) are open or shorted. Open data pins allow the phone to establish data transfers and usually limits the electric current input to 500mA max (USB specifications). Shorted data pins, as in every wall charger and most car chargers, means data transfer is unavailable and max electric current is not limited (usually 1000mA). (Just an extra info, if you short pin4 and pin5, the phone thinks it's on a charging dock and usually launches a dock app, for example, Car Home. If you close the app, it might pop back up, because the pins 4 and 5 are still shorted)

I am not sure how to get around this issue. If you short the data pins on the motherboard, you will never be able to use USB cable for data transfers. You could create a custom microUSB plug to put in the microUSB port on the outside of the phone that only shortens data pins. But you need to make it very short, so that it does not stick out of the phone, but long enough so that you can remove it and insert regular USB cable, should you need to copy files from/to phone. It's not gonna be pretty. Another idea is to modify linux kernel, so that it does not check the data pins when charging every time, only when you manually tell it too. But this is too complicated and so many things can go wrong. I, personally, would give up at this point and simply ignore the "mass storage" pop up.
