[MENTION=2924784]Product F(RED)[/MENTION] Okay. Thanks!

Should I buy exact same board kind of? I mean I have Rev 0.7 R.CB2 (kh) 12 on the board and K2c19 on the connector strip. Does it need to match with the item they sell in eBay or any Rev board in eBay which is meant for t889!

Once again thank you so much.
[T-Mobile Samsung Galaxy Note II] Product F(RED):
As long as it's got the T89 you'll be fine. I've replaced it before. Trust me.

Hi

I have international galaxy note 2 N 7100 , i also have 460 charging current on my note 2 wireless charging, which kernel will work best for me?
[T-Mobile Samsung Galaxy Note II] vinas1:
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:
[T-Mobile Samsung Galaxy Note II] farfromovin:
Vinas, do you use battery monitor pro or have other software to tell you charging current? Also are you using Perseus's kernel? Should up charging rate from about 350-500 ma to 900 ma.
[T-Mobile Samsung Galaxy Note II] vinas1:
Great point, yes I'm using Perseus's kernel with this. I was at about 40% last night and woke up this morning with 100%. I'll check out the charging current - I have a full charge now so give me like 14 hours (ha ha)! :laugh: One interesting thing to note (no pun intended) is that I was having a problem with non-oem chargers. It seems like the charger needs at least 750 milliamps of output to work - the OEM charger has 2 amps. The OEM part number is ETA-U90JWE. I have some crappy blackberry chargers that are hit or miss - my samsung 750milliamp works and so does the OEM like I stated before.
[T-Mobile Samsung Galaxy Note II] farfromovin:
Does it start indicating charging immediately or does it take 5-10 seconds to register like my Galaxy Nexus did?
[T-Mobile Samsung Galaxy Note II] vinas1:
It starts immediately within about 1 maybe 2 seconds at the most.
[T-Mobile Samsung Galaxy Note II] perryh1:
what size and type of wire did you use?

thank you
[T-Mobile Samsung Galaxy Note II] jpeps3:
Do y have a pic all ready connected

And chargeing

Or more pics were did y get the parts from...? Very cool mod

Sent from my SGH-T889
[T-Mobile Samsung Galaxy Note II] vinas1:
I used the smallest wire I had which was about 26 Guage. I salvaged the wire from a micro usb cable that I was using to test this mod. Afterwards I realized I could have used copper conductive tape. If I were to redo the mod i'd probably use the copper tape instead.

At the time I was worried about shorting other components, so I opted for super thin insulated wire.

If I get a minute to tear down my phone again I will. It's been sitting apart more than together during the last day... The parts I used were salvaged from a micro usb cable for the wire, and I used a thin piece of plastic to wedge the usb compartment down. The plastic bit I used was rectangular and about as thick as a credit card.

Edit: Pics attached of the wire and plastic piece I used.
[T-Mobile Samsung Galaxy Note II] jpeps3:
Can y please open it show the wireing please

Sent from my SGH-T889
[T-Mobile Samsung Galaxy Note II] farfromovin:
I'm assuming you used some N52 magnets perhaps, maybe 8 of them? Glad to hear you used 26 ga cause I got copper tape and 30 ga wire ready to go. I think I'll use the wire to avoid shorting as well.
[T-Mobile Samsung Galaxy Note II] vinas1:
I just tested the stock kernel again and can confirm that the disconnect problem with weaker chargers is not present. It seems that the higher charge rate in the Perseus kernel causes the weaker micro USB chargers to disconnect. The OEM charger works just fine, but due to the higher charge rate and the palm touchstone, it seems that the lesser amperage chargers can't keep up. The symptom when this happens is: set phone on palm touchstone, USB connects and disconnects over and over again. Again, not a problem on the stock kernel.
[T-Mobile Samsung Galaxy Note II] farfromovin:
Do you have the palm charger that comes with the touchstones too?
[T-Mobile Samsung Galaxy Note II] jpeps3:
So does it charge right or not and holds charge?

Sent from my SGH-T889
[T-Mobile Samsung Galaxy Note II] vinas1:
Unfortunately no, mine didn't come with them!

It charges and holds a charge perfectly. The conversation is about how quickly it charges, and that seems to take about 4 hours to charge from 20% to 100%
[T-Mobile Samsung Galaxy Note II] jpeps3:
Relly slow change

Can't you use cord it come with and open the cable use the wire

[T-Mobile Samsung Galaxy Note II] Turbo4V:
Just wanted to say thanks to Vinas1 for your work on this, and for posting up the pictures! I was hoping that I wouldn't have to crack the case open, but it'll be worth it in the end!

Thanks again!
[T-Mobile Samsung Galaxy Note II] degeneration:
I like what's been done in this thread, but I want to wait and see if there is something more... direct to solve our problem I guess. However I guess there's a chance that this will be the best we get. Poops.
[T-Mobile Samsung Galaxy Note II] farfromovin:
I think the only other option is to swap hardware with one of the other Note2 variants that have complete wireless charging hardware.
[T-Mobile Samsung Galaxy Note II] vinas1:
Agreed.

At this point my contribution to this thread is the workaround I documented. After spending several hours with the circuitry of this device, I could _not_ prove that there is wireless charging hardware missing. Judging by the sprint photos, there is a chip nearby that is not present in T-Mobile's version BUT when I tested the contacts, they each had different resistances across them (directly across to each other); which my best guess, was that the connectors for the missing chip are for some kind of channels or something - not necessarily a wireless charging circuit. So I am still hopeful that software can make this work without the work around. My motivation was to use the 3 touchstone chargers I bought before testing, and now I am although it took a lot more work than the international version! ~ :laugh:
[T-Mobile Samsung Galaxy Note II] mehrabrym:
I am a newb

Hi all, I am kind of new to this kind of hardware modification to my phone, and so I was wondering if taping the wires to connect them would work just as well without soldering them?
[T-Mobile Samsung Galaxy Note II] farfromovin:
Trust me, absolutely not. Even if you get something "kinda wedged" in there and you think it's working out it will fail when you need it most. Also, the likelyhood of something going wrong and shorting out is increased when you do modifications with that sort of work. You're far better off spending $20 at radio shack on a 25W soldering iron, solder, and wire and watching some youtube videos and practicing. Soldering is easy once you start!
[T-Mobile Samsung Galaxy Note II] degeneration:
So, a few questions about my trials in wasting money.

So it started when I ordered the backplate to a GS3 for wireless charging on ebay (it was 28 bucks instead of like 50 for the note 2) and I wanted to buy it because it had the little metal cubes for connecting to the phone, instead of curling up some bare wire ends and applying some solder which didn't seem as stable to me. Well the N2 is inverted in comparison to the GS3, so now I have the little palm charging coil (I actually have 2, I had an old palm pre coil, but again, I wanted the metal nubs) but I am not sure I can make it work since the pos/neg terminals are upside down. Any one know how to mess around with flexible circuits? I was thinking I could scratch away some film to make it work, but not sure if that is even the right idea, let along a good one. I am starting to think a little piece of wire and some solder and super glue to flip the terminals while hopefully insulating the circuit from the terminal. That might not make sense. Any how, any thoughts would be cool (I will add some photos a bit later, as I am going to write this post and take off for a bit).

Second, since someone else asked about it. I can solder, but I am not the cleanest of solderers, so I was thinking: could one use that conductive glue? Apply a little to the end of the wire and put it in place, or would that be messier/not work/etc?

Thanks for any info guys/gals/others.
[T-Mobile Samsung Galaxy Note II] KittyFae:
Conductive glue is rather hit or miss. The resistance it adds to the circuit is all over the place, almost to the point of not being usable at all.
[T-Mobile Samsung Galaxy Note II] degeneration:
Sooo... it might work? Like all other things consider, if I try maybe setting up an inductive charging circuit on an old phone and the resistance isn't too bad I should be good to go? I guess I am asking if the stuff USUALLY A) sticks well enough B) isn't too messy for this job.
[T-Mobile Samsung Galaxy Note II] xamindar:
This is really a shame. Maybe we can figure out what that chip is and order it somewhere? Does it look like that's all that is missing?
[T-Mobile Samsung Galaxy Note II] Turbo4V:
Just finished doing 'the mod', thanks so much for the write up. The case is a bit of a PITA to get off, which was probably the hardest part of the whole thing. I ended up using wire wrapping wire (30awg) to make the conection and it fit in there perfectly.

Right now I'm running the touchstone with a bench power supply (don't have my charger here), and I"m noticing that if the phone doesn't sit EXACTLY in the right spot on the touchstone, that it starts charging, but immediately stops (then starts again, and so on...) (I'm using the stock tmobile rom). Guess I'll try plugging the touchstone into the Samsung charger later and see if it works any better.

Again, thanks to vinas1 for the great write up!

Justin
[T-Mobile Samsung Galaxy Note II] KittyFae:
It might work, but the contact you have to glue is rather small so have to worry about bridging issues, and the quality of the paste. It works good enough for prototyping but not for long term use, since it'll eventually fall off after a while with the normal flexing of the case during use.
[T-Mobile Samsung Galaxy Note II] farfromovin:
Turbo4v- are you using any magnets? When I modded my Galaxy Nexus it worked waaay better with 4 or 8 magnets inside the battery cover to align itself with the touchstone. I plan on using 8 n52 magnets on my Notes.
[T-Mobile Samsung Galaxy Note II] elite-fusion:
where would you attach the additional magnets to? also wouldnt that interfere with the S-Pen?
[T-Mobile Samsung Galaxy Note II] farfromovin:
There are 4 round spots on the corners of the touchstone coil cover that have metal discs oeiginally. Replace those round thin discs with magnets and you get a decent aligning method. Double up magnets and it'll hold normal sized phones in a vertical situation.
[T-Mobile Samsung Galaxy Note II] Turbo4V:
No, not using any magnets. Is that what others are doing? I've noticed it's really tricky to even get the phone to stick to the touchstone sometimes, I have to move the phone around till it sticks.
[T-Mobile Samsung Galaxy Note II] Turbo4V:
... Oops, repost
[T-Mobile Samsung Galaxy Note II] elite-fusion:
with with regards to the S-Pen, would that affect it in anyway? That is usually why people say do not get cases that have a magnet closure to them because it affects the S-Pen
[T-Mobile Samsung Galaxy Note II] _Motoki_:
Out of curiosity, anyone know if this can be made to work with the larger easel style Touchstone for the HP Touchpad?
[T-Mobile Samsung Galaxy Note II] elite-fusion:
THIS IS SUCH BS! The AT&T version also has the Wireless Charging capabilities....are we seriously the only ones who dont? WTF
[T-Mobile Samsung Galaxy Note II] xamindar:
Yeah I'm going to complain. I hope samsung releases an official wireless charger them maybe we can return the phone as a warranty replacement
[T-Mobile Samsung Galaxy Note II] elite-fusion:
Im hoping that when 4.1.2 update comes up, they unblock the capability :(
[T-Mobile Samsung Galaxy Note II] xamindar:
They can't. Our t-mobile note iis are missing an ic chip for wireless charging. It is a hardware issue.
[T-Mobile Samsung Galaxy Note II] baronsamedi:
Assholes
[T-Mobile Samsung Galaxy Note II] KittyFae:
After searching the forums for a bit I've not found the answer to my question. If so, then I apologize for the clutter. In the past I've heard that the T-Mobile and AT&T variants are hardware identical, insomuch as the dormant LTE radio in the T-Mobile versions. As per the missing IC/whatever in the T-Mobile version, has anyone verified that the AT&T version physically has the missing component not found on the T-Mobile version?
[T-Mobile Samsung Galaxy Note II] degeneration:
That is probably true, but hasn't been confirmed. There are hardware differences between ours and the sprint model. There is a difference near the charging pins, but there is a chance (probably small) that those aren't related.
[T-Mobile Samsung Galaxy Note II] elite-fusion:
I wish someone with the at&t version can pop ot open and confirm for us :(
[T-Mobile Samsung Galaxy Note II] crazy talk:
Anyone know where we can buy a affordable QI receiver pad that will fit under our battery doors? been thinking about buying a battery door for an LG spectrum and trying to see if i can rip the goodies out of it.

I have a bunch of touchstones, but 500Ma is a bit slow for a battery this big.
[T-Mobile Samsung Galaxy Note II] vinas1:
I opened my GN2 up again and added pics from the work around mod on the first page. For those wondering, yes it's still working although the last picture shows some stress on the wire I used. Still works though! :good:
[T-Mobile Samsung Galaxy Note II] aaldere1:
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.
[T-Mobile Samsung Galaxy Note II] elite-fusion:
If this is actually true, and you say it works, do you get the notification on screen that the phone has been connected to wireless charging? or does it work the same way by soldering the wire?
[T-Mobile Samsung Galaxy Note II] cajunflavoredbob:
Here's the direct link for those interested.

I don't get it. What does a new micro usb board have to do with the wireless charging board and its missing chip?
[T-Mobile Samsung Galaxy Note II] farfromovin:
x2^ I'll happily buy 2 of these if it makes my notes say "wireless charging" when on the touchstone.
[T-Mobile Samsung Galaxy Note II] crazy talk:
WTB: More details aaldere1!!

does it work seamlessly on the stock rom with no modifications? does wireless charging come up on the OS?

can you get some detailed pics of the two boards side be side?
[T-Mobile Samsung Galaxy Note II] aaldere1:
Sorry for the delayed response. I'm traveling now so I won't have access to more detailed photos until next week. Basically the answer to your questions is yes, the wireless charging window pops up after replacement. Stock Everything. I do want to note that this Note II is running Jelly Bean. Not sure if that matters.
[T-Mobile Samsung Galaxy Note II] farfromovin:
You wouldnt happen to have a touchstone with you would you? Id really love it if you could provide a screenshot of your wireless popup maybe? Just trying to be a littke cautious before spending $50 on some more than likely unreturnable parts from china.
[T-Mobile Samsung Galaxy Note II] aaldere1:
It was the mod mentioned earlier with the Palm Pre station. I will get a screenshot for you.
[T-Mobile Samsung Galaxy Note II] vinas1:
Excellent find! After searching for the part number, I came across this version which does have the 3 pins http://www.parts4repair.com/samsung-galaxy-note-ii-n7100-dock-charging-connector-board-flex-cable/

Hopefully this is the solution which gives T-mobile users some options to get wireless charging working (either purchase the new micro USB board, or use the jumper wire method)! Once we get a screen shot of the wireless screen charging I'll add it to the front page. :good:
[T-Mobile Samsung Galaxy Note II] aaldere1:
I'm not sure if the difference in the actual part is what made it work. I believe by getting the one with two pins, that is what made the mod work, which was surprising and also awesome. I'll get a screenshot for you today sometime and post it.
[T-Mobile Samsung Galaxy Note II] crazy talk:
that one says T-889 right on the board, so i have a feeling that board doesn't have the wireless charging circuitry in it.
[T-Mobile Samsung Galaxy Note II] aaldere1:
Here is the screenshot of the charging window with the replacement part I mentioned in the earlier post.
[T-Mobile Samsung Galaxy Note II] jester450:
Nice find. Just ordered one.
[T-Mobile Samsung Galaxy Note II] elite-fusion:
Hey, report back when you get it :) if this thing works, im ordering one too :)

Also, I have been seeing online that there are QI chargers for the S3/N2, which do not work with the Touchstone, but do work in fact with the energizer pad, does anyone know if it will make the N2 charge via QI reciever instead of the pre/pixi/powermat?
[T-Mobile Samsung Galaxy Note II] aaldere1:
FYI this modification with the Note II does not work with the Energizer pad charging station. Just the Palm one.
[T-Mobile Samsung Galaxy Note II] harpocrates:
Hi,

I did the usb mod mentioned with the instructions from the jpeg and it seems to work ok when the phone is off and on dock, but when the phone is on and charging via dock it keeps making a sound as if im connecting the charger and it seems like im disconnecting and reconnecting the chrager..charges fine via usb...

Any clue why its doing this?
[T-Mobile Samsung Galaxy Note II] aaldere1:
Had this same problem and it was the wire connection. Make sure it's having constant contact on all wire connections.
[T-Mobile Samsung Galaxy Note II] elite-fusion:
Yes, I know that this wont work with the energizer one but only the touchstone, but there are receivers out there that connect to the two pins in the phone the same way as the pre/pixi but they have QI technology instead and they supposedly work with the energizer pad, So i want to know, without purchasing that spare part, will it work with the QI reciever? Maybe our phone doesnt recognize the palm one, but would recognize the energizer one?

Also would like to know if the energizer one will charge the phone quick via QI technology compared to the touchstone with the pre/pixi technology?
[T-Mobile Samsung Galaxy Note II] vinas1:
Try to make sure you have the stock kernel, some other kernels increase the charge rate which apparently can cause this issue. Also, try to test it with the OEM gn2 charger as that would work for me even with an increased charge rate. Other than that double check the wires. Rest assured it will work with stock kernel and good wiring.
[T-Mobile Samsung Galaxy Note II] jester450:
Trying to source a Qi charger and receiver that doesn't cost to much.
[T-Mobile Samsung Galaxy Note II] elite-fusion:
I found the receiver for 30-35 and also the regular energizer pad for about 55 at bestbuy, but thats about the same if you buy the fully built battery cover from ebay that comes with the touchstone already.
[T-Mobile Samsung Galaxy Note II] crazy talk:
the QI setup should charge at 1Amp, twice what the Touchstone setup is capable of.

where are you finding the receiver for 30-35?

you'll still need a chip to drive the QI antenna. can't just hook those leads straight to the N2.

so you would need one of these as well http://www.mouser.com/ProductDetail...013ARHLT/?qs=sGAEpiMZZMslbOXsVR1ov0Of4cGjSEnn

i have no idea how one would hook that all up, looking at the data sheet it looks a ton more complicated than 'inputs here' and 'voltage out here'

Replacement board comparison

After looking at the Parts4repair board (SGH-T889) and the Chinagadgetland board (GT-N7100) I noticed some component differences. Not sure at this point what their effects are but just though I would point them out. The T889 board has an entire extra IC with caps & resistors on the right side, above the USB port it has an extra diode, and just to the right of the USB port there is a capacitor missing.
[T-Mobile Samsung Galaxy Note II] JScrog:
Missing IC

From What I've seen of the Palm Touchstone mod it looks like the chip we are missing (compared to the Sprint model) is probably the controller for the coil. If someone could get the markings on that chip I would be more than happy to look up it's datasheet.
