The linked thread is in the N7100 forum, so he's not using our device.
[T-Mobile Samsung Galaxy Note II] nm8:
Hi all sorry I didn't mean to mislead y'all. You should be able to use powermat instead of palm.
[T-Mobile Samsung Galaxy Note II] Poke_N_PDA:
So it looks like there are plenty of Qi pads out there for the N7100 variant of the Note 2. Who in here has got that working? Seems like it would just be the same thing with different tech.
[T-Mobile Samsung Galaxy Note II] ttabbal:
You can use the Qi receiver, but it has the same issue as any other receiver, you need to make that connection or it won't work. Bummer that TMO gimped it.
[T-Mobile Samsung Galaxy Note II] Poke_N_PDA:
It's not entirely T-Mobile since AT&T has the same physical device, but it is strange. Why go out of your way to break a feature?

Edit: oops, not the case.
[T-Mobile Samsung Galaxy Note II] farfromovin:
Yeah, I have both my Tmo Note II's working with QI receivers and Nexus 4 orbs. It only charges at 500ma unless you use a kernel that alters it. I charge at 1A with Perseus kernel. It's a lot stronger field than the touchstone setup. I charge through my thick 2 piece Seidio case no problem :good:

I am a little sick, so maybe I am being dumb here, but if this board works, that doesn't allow you to use wireless charging, right? The board doesn't have anything to do with the wireless charging circuit, correct? No one else asked and I am not sure if it's because people already figured out the charging board doesn't matter (searching only found that some people had problems with some boards) or if no one asked yet. Googling seems to say N7105 works with wireless charging.
[T-Mobile Samsung Galaxy Note II] pcorlatan:
The board does nothing different, it is exactly the same as the tmobile USB board. There is still the possibility of connecting a wire to the +5V connection on the board like in the original mod but I'm not willing to try soldering it again yet.
[T-Mobile Samsung Galaxy Note II] Vanquiz:
I'm using the green Qi receiver from Ebay, and Metrans MWT02 transmitter.

After the mod, didn't work well couple times, the charging stop after 10-15 minutes, maybe because it got too hot, I can feel the back cover is a bit more than warm. Maybe it got something to do with the metal plate for my I Magnet, removed the plate, and able to charge at least for an hour and I took it off to check the battery charged from 48% to 62%, didn't feel warm at all.

i tried this hack with a "Powermat" brand charging kit as well. pulled the receiver coil from a blackberry Powermat case and tested it to output 5V when touching the pad.

without soldering the tiny wire internally, it does nothing as expected. after the wire is soldered in, the battery icon shows charging, but the battery level

does not go up

.

battery monitoring widgit shows discharging still. Internal settings show connected to USB and charging, but i doubt its correct.

I am using Jedi X11 ROM.

i didnt like the way the phone casing couldnt close completely so I am abandoning this project till i can find thinner wire.

also i am not sure what kernel Jedi X11 uses.

Most problems on Phones without the built in Induction charging and Modifying the receiving coil directly to the usb contacts or such , is the coil, phone and the charger aren't communicating which is what all Wireless charging system do...
[T-Mobile Samsung Galaxy Note II] farfromovin:
I'm sorry but your post makes no sense. There is no "data communication protocol" involved here. It's inductive coupling and copper wire. By this I simply mean that my phone (SGH-T889) charges wirelessly. It doesn't have a popup that says wireless charging. That doesn't mean basic electronic principles are tossed out the window though :p
[T-Mobile Samsung Galaxy Note II] sircody:
Oh so you think the Battery tells the charger, whom it's never met, to stop charging because it's full or when it needs to trickle?? LOL

---------- Post added at 02:10 AM ---------- Previous post was at 02:07 AM ----------

I'm sorry, i didn't know it had the wireless contacts built in beside the battery, or else why does it have that app, wireless charging notification...But no matter what you think, there is communication between the two...It's been that way for over 100 years, when this was invented
[T-Mobile Samsung Galaxy Note II] sircody:
See that little Circuit Board on both styles of induction Coils...that's first clue...
[T-Mobile Samsung Galaxy Note II] farfromovin:
Look, you got it all wrong. I'm saying that by attaching an inductive charging system to your USB port, electrons don't care if they travel from the USB wire, or the WIRE YOU PUT THERE, into the battery. No matter what phone, can be modified to charge wirelessly.
[T-Mobile Samsung Galaxy Note II] degeneration:
I think what is trying to be said somewhere in here is that the coil has nothing to do with how the battery charges minus maximum rate. The coil sends power through the inboard charging circuit. It just wants power, it doesn't really care from where, and it will work with the power it is given in whatever way it is designed. The coil and the battery do not know that either really exists. The coil's circuit is connected, so it sounds out power, which the charging board receives. The battery receives power, and it charges, thanks to the charging board making sure that the power is something the battery can work with. Coil and battery don't directly interact. Maybe the coil is hoping for information about the battery, depending on the coil's attached circuitry that you are using, but I sort of doubt that since most of the coils are set up to be slightly universal. The palm touchstone was used across a few different palms, so there is a good chance palm made one coil for all of them with nothing really proprietary besides the connector.

All of the connectors on coils (palm/qi) I have seen are just pos/neg connectors, so I really doubt they are checking for battery stats.

Bummer. No chip for wireless charging on T-Mobile versions

Somebody in the beginning of the tread mentioned that Sprint version has "something" soldered next to wireless charging contacts that is missing on Tmo version (http://dl.xda-developers.com/attach...15a72fb/1/4/6/9/7/4/0/IMG_20121109_143326.jpg). There is another tread is going for Sprint GN2 and there is a picture. that missing "something" is a chip marked II-K4 (http://dl.xda-developers.com/attach...d703e98b3/515a7661/1/7/8/5/3/0/8/IMAG0733.jpg).

I guess that's how GN2 detects wireless charging.

Sorry to be dense, but does the Qi kit below allow for successful wireless charging without any kind of soldering?

http://www.ebay.com/itm/Qi-Wireless...S_Cell_Phone_PDA_Chargers&hash=item1e788b1daf

Edit: It looks like it still needs a tiny soldering job (mentioned in the OP). I know this sounds lame, but anyone from the San Francisco Bay Area who could do this for me? Of course, I'll pay for the job.

That doesn't sound lame at all. I really want to do this mod as well, but I just know I'm going to break my phone.

The pins on our phone are disabled so any wiurless charging mod requires soldering
[T-Mobile Samsung Galaxy Note II] Product F(RED):
Disabled, as in not connected to anything? Or the USB flex doesn't support it? I have both a T-Mobile and AT&T Note 2 (with a Qi charging patch and charger). I'm just trying to understand through comparison. I'm wondering why they even included the pins in the first place, since the Sprint version doesn't have them (the contacts are there if you drill holes through the midsection but no actual pins).
[T-Mobile Samsung Galaxy Note II] cajunflavoredbob:
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.
[T-Mobile Samsung Galaxy Note II] Product F(RED):
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.
[T-Mobile Samsung Galaxy Note II] cajunflavoredbob:
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.

[T-Mobile Samsung Galaxy Note II] Product F(RED):
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.
[T-Mobile Samsung Galaxy Note II] cajunflavoredbob:
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.
[T-Mobile Samsung Galaxy Note II] xamindar:
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.

Did anyone tried the "CircuitWriter Pen"?

I have one and I am tempted to try it.

Here is what I'm talking about:

http://store.caig.com/s.nl?sc=1&category=&search=circuit
[T-Mobile Samsung Galaxy Note II] vinas1:
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!

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.

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.
[T-Mobile Samsung Galaxy Note II] siraltus:
I opened my phone and thought about doing this mod, but running the wire, even a very thin one, causes the speaker cavity to not properly mate to the PCB and chassis the way it's described, which screws up several things:

Acoustic seal around the microphone no longer seals the mic tunnel to the microphone. This will screw up noise cancellation and call audio.

Less tension on the speaker and antenna contacts means at some point those connections can become intermittent. No thanks.

Dust seal around the USB connector no longer seals off the rest of the phone from dust. I don't want dust getting deep into the phone through the USB connector.

The only way to do this mod reliably is to route the wire outside the speaker cavity module, not under it, and have it enter the target solder point through the tiny space between the die-cast chassis and the cavity module in the middle of the module, but then the phone won't close properly, so a little filing of the plastic is required on the outer edge of the speaker cavity module.

All this trouble while my stock charger can charge the phone twice as fast? I'll stick with the stock charger.
[T-Mobile Samsung Galaxy Note II] premiatul:
That's why I said to take it to a repair shop. They did it a little bit different than the OP.

From point A to the upper corner, they run a flat copper tape and from there a soldered solid wire to point C.

I have no problem with closing the cover, it is like it's nothing there.

They did cover the flat tape with some kind of liquid that hardens and isolates. It actually looks like factory made.
[T-Mobile Samsung Galaxy Note II] siraltus:
Resin lacquer over copper tape - good idea, but we're talking fractions of a millimeter tolerances here, it will still lift the speaker cavity module enough to break the airtight acoustic seal around the microphone and the dust seal around the USB connector. Take the module out and examine it very closely, you'll see there's an area where the module's thick enough to sit completely flush against the USB PCB, any lift there will lift it enough for the mic seal to fail. Copper tape gives me an idea on how to route it around the speaker module, though. I'll poke around this weekend.

Well, I have no problem with the mic or anything else, PLUS I have now wireless charging.

Anyone want to buy my touchstone charger and receiver? Started to install but never finished
[T-Mobile Samsung Galaxy Note II] rubin110:
So I've tried this install with the Qi charge for the Note II off of Amazon. The Qi charging base changes color when the pad is on top of it, but my Note II doesn't indicate that it's getting a charge. I'm running CM11 M8. I'm fairly certain my solder joins are good. Any help would be appreciated. Thanks.
[T-Mobile Samsung Galaxy Note II] vinas1:
I'm using with a Qi charger for many months now. I think the only real problem is making sure the phone is "squared up" on the receiver part of the charge pad. If the base changes color, that typically means that the Qi pad that you installed in the phone is receiving a charge from the Qi base. Some problems that I have ran into since I created this mod:

Charger amps - The Qi pad will drop the charge rate, to combat this make sure the charger is a 2000mA charger (the stock charger has always been recommended for this reason)...

Kernel - try a stock kernel until you get this working reliably. Some kernels try to charge at different rates, this can break inductive charging.

Connections - try holding your hand over the pins from the charge coil to make sure the pins are making excellent contact with the phone charge pins. Hold the connectors and move the phone to and away from the Qi base pad to see if it starts to work while you are holding it.

Qi Pad Quality - if you are sure you're doing everything correctly see if you can find a friend with another Qi pad that you can try. I've had cheap Qi pads not work.

If all of the above still doesn't work, my guess would be electrical issue. Good luck and I hope you get it working with the rest of us!

Fast(er) Charging with T889 Wireless Charging Mod

Hey guys,

I don't know if someone has posted this already, but I thought I'd post my 2 cents... After doing this mod I was really disappointed with the ridiculously slow charging rate of 460mA. I was also surprised with the amount of BS on the "interwebs" regarding why the T-Mobile variant of the Note 2 (SGH-T889) was limited to such a slow charge rate. So after ordering a bunch of "wireless receiver pads" on Amazon, tinkering around with various ROMs and Kernels, and playing with several different Wireless Charging Stations, I've finally found a wireless setup that charges at 1000mA.

Here's the deal:

1) Not all "Wireless Receiving Pads" are created the same. What I'm calling a "Wireless Receiving Pad, is the $8-12 "coil pack/receiver" that sticks to the phone under the back cover. Basically, there are a bunch of geniuses online who claim that if you have a good quality wall-wart / AC charger (such as from a Blackberry, tablet, etc.) powering a good quality Qi Charging Station, then you will be ok. This is only half true. You are obviously limited to the OUTPUT (not INPUT) induced charging current of the Wireless Receiving Pad. Of the 3 I bought on Amazon, one maxed out at 500mA, one got 800mA, and another got 1100mA. I will post details of the one I ended up staying with which cranked out 1100mA. Being limited by the output of the charging pad was the first limitation I thought of, and God knows I'm no genius! So MAKE SURE YOU HAVE A WIRELESS RECEIVER CAPABLE OF A DECENT CHARGING RATE!!

2) Once you have selected a solid Wireless Receiver that is actually capable of outputting a decent induced charge, the next obvious step is to overcome the 460mA boundary set for USB charging. This is obviously controlled by the phone (hence plugging in different chords -ie: some with shorted Data +/- vs. non-shorted) result in different reference charging rates. This is easily resolved by using an aftermarket Kernel that's not half-baked like 80% of the Kernels out there. I recommend Agni's Kernel: http://xdaforums.com/showthread.php?t=2602053

I like Agni for many reasons, however in this specific scenario I really like the "Agni Control" app which will allow you to change the USB reference current up to 1200mA.

3) Use an app like Galaxy Charging Current Lite from the Play Store to determine your current charge rate.

That's pretty much it! It took me 40 minutes to write this article (at work, multitasking) and my phone charged from 66%-90% on a cheap $22 PowerBot Charger from Amazon! I'll post more details when I get a chance, such as pictures of the Receiver, Charging Pad, Kernel and ROM specifics, etc.

Cheers!
