[T-Mobile Samsung Galaxy Note II] vinas1:
This is a fork of the original N7100 Note 2 wireless mod thread found here:

The purpose of this thread is to determine why the wireless charging pins on the T-Mobile Galaxy Note 2 (SGH-T889) are not working after installing the MOD above.

Please view the thread above for more details about the original MOD, and to see what you need to do first in order to continue with the work around below.

Updated method on 8-5-2013: Thanks to SGBE

The updated method has a better solder point. See that thread OVER HERE.

The Work Around: (verified working on multiple devices)

We have a mod to make wifi charging work! Regardless if the T-Mobile GN2 is missing hardware or not, the work-around is a low cost (free?) alternative to get wifi charging working. Our work around involves soldering a small wire to a tiny point on the micro usb board. You should be able to solder a very small connection (about the size of a pen tip) before attempting this.​

The mod/workaround below is verified working with the stock charger and stock kernel. <- Pay attention to that last bit. :cowboy:

Workaround Known Issues:

Some kernels have a charge rate which is set too high for the PALM PRE Touchstone to work with. Likewise, some non-oem chargers can not deliver enough amperage to continuously charge the device wirelessly through the Touchstone. Therefore, if you have any problems (disconnect/reconnect proble), be certain that you are using a stock charging rate (kernel controlled) and a stock Galaxy Note 2 Charger (2,000mA). If you are still having problems check your mod for trouble, and finally post up and maybe someone can help you.

The full work around post is on page 3.​

New Information:

If you have new information on a hardware or software fix then it will be added here. Until that time, proceed with the workaround at your own risk. Once again, the work around instructional image is HERE.

WARNING: What was claimed to be a fix in the section below did not work, and ultimately people wasted money on bogus hardware. It is here for historical reference.

The Fix

You may need to purchase some missing hardware.

See page 7 for details (you need to replace the flex cable and micro-usb board): http://xdaforums.com/showpost.php?p=34380437&postcount=65 The SKU number for the board is MBRPSS964.

Older info:

Some steps that I've personally done:

Completed the wireless mod above, confirmed wireless voltage reading of 5.56vdc.

Tested continuity between USB positive, and wireless positive - no connection.

Tested continuity from the negative wireless charging pin to the negative USB, SIM slot, various screws - they are connected.

Jumped the positive post on the USB to the wireless charging positive pin, the phone charges but is not practical to have a wire hanging out of the USB port.

I plan to pull apart the phone and check the paths from the positive and negative ports on the wireless pins. Attached is a picture from a SPRINT GN2 that does not have the pins, but supposedly works for charging once contact is made with the pads. I'm going to be using this to compare the circuit against my T-mobile version.
