It's a mystery we've all been wondering, man. The pins are there, but they seem to be grounded out or simply not connected to anything. The soldering is required on the t889 to get even a small 750mA current running through it. Personally, I never bothered with it, though this is one of the more intriguing mods I've come across here.

I personally don't like major hardware mods, and I knew what I was doing when I switched to the T-Mobile Note 2. I just hate the RAT lock AT&T puts on their modems (can't switch off LTE, among other things). As dumb as it sounds, freedom of software was worth more to me than wireless charging, which was nice for late-night charging. But anyways, like I said, I was just curious. I could buy the i317 USB flex and put it in my T-Mobile version and try it out. I already have a second T-Mobile version that needs it replaced, so I might as well try.

Considering the battery on this damn thing lasts me two full days, I think I'm doing good without the need for a hardware mod, clever as it is.

Screenshot is with 5 hours screen time. Carbon nightlies/Neak Kernel/Inverted apps combo.

I don't know how you get such amazing battery life. Seriously, I can get maybe almost 3 and be at 50%. I'm using an N7105 based ROM with a stock kernel. Maybe I should try out a custom kernel. Just don't want anything that takes away from the smoothness.

I'm underclocked and undervolted on neak. That combined with inverted apps helps a ton. Inverted apps in my sig, if you want. Send me a PM if you want to continue the conversation, so we don't derail the thread.

The usb flex will not work. I did the solder mod on my tmobile note ii so I had plenty of time inspecting it and poking with my multimeter. The pins are not physically connected to anything.

Before i did the mod I actually bought a usb flex that was mentioned earlier in the thread by some complete idiot. It of course does not work. In fact, the connector on the international version flex are not even pinned the same on the tmobile version.

Circuit Pens not recommended for this mod. Grounding issues and reliability issues with conductive pens. To answer your question directly, I have tested with my conductive pen and it is difficult to maintain a path for any significant distance. These pens are probably good for minor repairs though, just not this mod. The path is pretty long and even if a conductive pen could be used, the risk of shorting is pretty high. It may be possible to use conductive tape, but reliability issues are likely.

I'd like to take this opportunity to mention that the original mod which I posted is still going strong on my phone. Cheers!

My phone is also trucking alone nicely still. Been using AOSP ROMs and Devil kernel to charge at 1100mah at night. Works perfect!

Do you guys think a cell phone repair shop would do the soldering on this? This is really the last piece of the puzzle now that I've got Wallet working...

I have asked 3 of them but they didn't want to do it. Then, on the 4-th one, they said they will do it and it will cost me $40.
In one hour it was ready and they showed me a picture taken inside the phone with the mod. I am very happy.
If you are in So California, I can give you the address.
Otherwise you have to go in a few of the repair shop and show them a printed picture of the mod and see if they want to do it.

Now that I have the wire soldered in place, can someone give me the links for the best power mat and coil that we can buy and will work with the Seidio case?
Thanks

I found a place that will do the soldering for me. What kind of wire should I have them use?

I didn't tell them anything else, just gave them the picture with the mod and the phone. They did the rest. They should have everything that is needed, as they are a repair shop.

OK....after the soldering mod, I got the wireless charging from here:

http://www.amazon.com/dp/B00D3F3N3A/ref=pe_385040_30332190_pe_175190_21431760_3p_M3T1_ST1_dp_1

and it works great, EXCEPT when you watch a video, the battery STILL goes
down (very slowly), but it does not effectively charge.
I have Perseus kernel and I "tweaked" all the charging settings to max.

So, I'm thinking maybe there is another charging Receiver that is better than this. If anyone knows a better one, please post it here.
Please post your findings here.

Thanks!

I'm still debating whether or not to do this. I'm kind of afraid that my phone will catch fire or something...

I just got the Samsung wireless charger and it is very nice, with a nice design, BUT it is very 'sensitive". What I mean, is that if you move the phone even a 1/4 of an inch away from the center, it will stop charging.
The Chinese knockoff it has no such problem.
So, go ahead and get the cheap ones. ...
Other than that, everything works perfectly with this mod.

    Here ya go! Keep in mind that this is my wireless volt mod (as in, the way I did it) and as such, any improvements are welcome! I'm very happy with the mod so far. The phone did a full charge over night with no problems. It was very nice just to pick it up off the touchstone this morning! But as usual do this at your own risk! The person doing the mod should be reasonably proficient at soldering small joints. Just be careful and this will work for you. Instructions are on the JPG! Any questions please ask! Verified working on the stock kernel and stock charger. :good:

    This is a fork of the original N7100 Note 2 wireless mod thread found here:
    http://xdaforums.com/showthread.php?t=1951493

    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.


    Results:


    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 Mod / Workaround:
    (also attachment #3 on the list below)

    attachment.php






    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.
    (the false wifi charging image is only attached for historical reference)






    Picture legend:
    1. Sprint GN2 chip (the chip is missing on T-Mobile's version)
    2. Sprint GN2 pin pads
    3. Wifi Charging work around instructions
    4. Completed work around example.
    5. alternate view of work around charging pin
    6. alternate view of work around +5vdc source
    7. Picture of the wi-fi fix working (reported that this may be a fake!)



    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.

    As it stands now, I jumped the USB 5vdc internally with a tiny wire, over to the wireless positive pin. It's working, although it was a tough mod. But it is totally internal so I guess this will have to do for now. So I have wireless charging (kind of, it works teh same as USB) on the T-mobile Note 2 now. If anyone wants to do the same thing, post up a pic of the board by the USB plug and I'll label the connector that you can use for the 5vdc source. The reason it's a tough mod is because you have to solder a small connection to the board under the capacitive touch buttons. It took me about 4 hours to find a good power lead on the board and make it all work internally!

    Hey gang. Wanted to update every one of you on this thread because we were able to get it to work on the Note II on the T-mobile network with a very simple fix that required no wiring, etc. It did, however, require that you purchase a Dock Charging Board Flex cable part that fits perfectly on the bottom of the circuit board. It will cause no functional changes to your phone, either. Wireless charging works in addition to plug-in charging.

    Because I'm a new user, I can't post links to the purchase store where I bought it but you can go to the website: China Gadget Land and do a search for charging flex cable n7100 - that one result is the one you are looking for. The SKU is: MBRPSS964

    Those of you who still want a link can just PM me to find out info about it. I'm also on twitter: @aaldere1

    The main difference between the two you can see by the picture attached. The default T-Mobile flex cable has 3 pins on the upper left corner, while the purchased one has two, plus a bit of a difference in circuitry.

    We thought originally that this woudln't work but there isn't any functional difference in the phone at all with this part. Again, this is a T-Mobile Note II. Works great.

    The good news is that this flex cable can be interchanged with your default one so if something doesn't work you won't have to severely modify your phone to get it back.
