Sounds like you removed the flip cover from the QC foilio case? How difficult was it?

Can you put some pictures up of how the folio case back looked after dremmeling?

What case did you try putting the dremmeled case back into?
[G3 Accessories] mixxxk:
i was using an otterbox defender, but it wouldnt charge thru the case. however the back folio case dremels down and snaps right into place. if u decide to dremel, just follow the snaps, dremel down to right before the snaps.

so i ordered this off ebay and a tempered glass screen protector, so hopefully this will work .
[G3 Accessories] sailindawg:
I think I get what you see dremmeled , you simply dremmeled the case edge before the snap to lower the side closer to the snap?
[G3 Accessories] Pilz:
What is the thickest case that someone has used the PMA coil with? I have a Spigen slim armor among others (Spigen ultra hybrid, Caseology, cruzerlite etc..) What would you recommend for the case so the coil still allows it to charge?
[G3 Accessories] mixxxk:
yes, because the att folio case wraps over the phone somewhat, so i dremelled down the sides and shaved a lil off the top so everything lined up.
[G3 Accessories] awtryau89:
Really nothing works with the PMA inserted into the back. Its even finicky with just the back cover. I had a Slim Armor and Diztronic and neither worked. I did have a Spigen Slim snap on case that worked but it was very very touchy. I finally solved my problem. I sold my AT&T model and just purchased the T-Mobile version and Qi back.

I confirm the pma pads being very picky about placement. I keep going back and forth about buying tmo phone [emoji19]
[G3 Accessories] sailindawg:
My wife's padphone x, is very touchy about where it lines up on the Duracell charging pad. The phone has to be half on, half off, in order for it to be seen by the pad. If I could find her a single device pma pad that was more forgiving on placement, I'd get it. Seems the G3 behaves similarly. Not a great way to roll out a barely used charging standard.
[G3 Accessories] mixxxk:
i have the orange nilkiin case with an Icarez 9H Tempered Glass scrren protector. i have AT&T so i had to buy the folio case, wonderful PMA, and i dremelled it down, so it snaps right in place.i can confirm the bumper case fits nicely with the protector, and wirelessly charges with no issues.

i tried the Qi USB receiver, but the phone kept telling me about it being a slow charge. which it was, didnt even get full overnight. anyway, just posting my findings.

When u say u took the quick circle case sticker off ...how hard was it to take it off ? And did u get the quick circle case from Amazon ?
[G3 Accessories] mixxxk:
I didn't remove the sticker from the folio case. I cut the front part off, and dremelled it down. Being the att variant is larger than the standard back. I went to an at&t store and asked if they'd honor the 50% off deal they were offering with the g3. And they accepted. It made it easier to rip apart a $30 case instead of $60 ?.

Battery doors with built in wireless PMA

Hey everybody... I am going to have AT&T battery doors with Powermat charging built in manufactured.

I need your help!

I need photos of the back of the AT&T G3, the Powermat sticker/chip on the folio case, the PIN layout, etc. I do not have an AT&T model. So with your help and as much information as you can provide me, I will make this happen for us all.

ANY information and detailed pictures you can give me will help me communicate how it needs to be made.

Thanks, lets get this done!
[G3 Accessories] iazybandit:
Why not send pictures of the Qi? If you knew anything Mr. "I have a bachelor's degree in electrical engineering from Columbia University (Fu institute). I understand how electricity works." (http://www.reddit.com/r/LGG3/comments/2ekb2f/lg_g3_oem_wireless_qi_charging_battery_door_for/ck0oatx), the pin layout is the same as the Qi. Sending pictures will do nothing. They will need to test the phone to find out the frequency and other information about the PMA.

But I'll do you one better. I actually sent a AT&T phone to a manufacturer for them to actually do REAL research on the phone.

Btw, I'm still waiting for my $200
[G3 Accessories] inaudible101:
Hey guys.

I skimmed through the thread and it doesn't look like anyone has come up with a solution for qi charging for the d850. I just picked one up and I think I'm going to actually solder a receiving coil to the USB port. I have done this mod on a One Plus One and you can see my threads here.

http://xdaforums.com/oneplus-one/general/internal-wireless-charging-t2819398

and

https://forums.oneplus.net/threads/soldering-in-an-inductive-charging-coil-internally.57772/

I looked at some screen shots of a teardown of the G3 and it looks like it will be very similar to the mod I did on my OPO.

Here's the picture showing the port. http://www.ubreakifix.com/blog/wp-content/uploads/2014/05/ubif-g3-22.jpg

So looking at the back of the phone the positive should be on the left and negative on the right if I recall correctly. I will of course test with a multimeter first. I may have to remove the NFC antenna if it blocks the signal, but if I can get this working I can just order a new one off ebay.

I'll probably take a crack at this over the weekend and update you guys with some pictures.
[G3 Accessories] iazybandit:
I'm working with the manufacturer. They should have the PMA soon.
[G3 Accessories] inaudible101:
PMA is not compatible with qi correct?

I already have qi chargers everywhere so I will not consider PMA if it is not compatible.
[G3 Accessories] iazybandit:
PMA is not compatible with Qi. AT&T, Rogers and Bell use PMA. If you're heavily invested in Qi and you have a AT&T, Rogers or Bell phone, you won't be able to charge wirelessly unless you buy a universal Qi receiver that occupies the charging port.
[G3 Accessories] inaudible101:
You should go back and read my post you quoted initially...

My modification uses the USB port charging pins but leave the port open for utilization.

How are you making out with the Qi soldering mod on the AT&T G3? Has surgery been successful?
[G3 Accessories] Pilz:
It would be interesting to see if this works. I still have my D850 ( it might go up on eBay soon because I haven't used it since I got my F460S) and it would be nice to see a workaround.
[G3 Accessories] sailindawg:
If one has good soldering skills
[G3 Accessories] inaudible101:
So I'll have to appologize for my crap soldering skills, but here's my progress so fay.

I was able to try about five different soldering routes for the ground, but for some reason I can not get it to charge with the plastic piece on that covers the back of the USB port. With the bottom part off I am able to charge at USB speeds without a problem. I worked on this for a few hours this morning and am done for now. I might take another crack at it in a few days. I'll update you guys if I have and success and if I get it all working reliably I'll create a new thread and post everything I had to do.

Here's an album of my really crappy looking soldering job. USB port functions completely without any issues.

what is the tape thing with 2 copper wires for? I thought it was for wireless charging, is it like NFC?
[G3 Accessories] pluginre:
Yes that is for the NFC

Just Buy T-Mobile LG G3

Or you guys could just buy the T-Mobile version and get a back with wireless charging... or better yet just by the sticker that has been going around for T-Mobile G3s.
[G3 Accessories] Pilz:
That's not a practical solution for most people. Hopefully there will be some form of a solution for everyone else.
[G3 Accessories] oblivinated:
I know... but AT&T screwed us over already by insisting that the G3s they carry are only compatible with the PMA standard. At this point, there really is no practical solution.
[G3 Accessories] Pilz:
I agree Att did screw people with that. That's why I have a G3 Cat 6 and the D850. Not everyone can just go get another phone for many reasons. I think that a solution is possible but it will entail a PMA sticker that will fit like the qi. That's the best case scenario this point.

Replace hardware

Hey guys,

Would it be possible to replace the PMA hardware with the Qi hardware from another phone? Just asking a question, pretty new to all this.

OR

Would it be better to buy the T-mobile variant and unlock it for the Qi and would you get 4g LTE?
[G3 Accessories] Pilz:
Buy the TMobile one because it has qi and an unlocked BL. You will get LTE in ATT as far as I know.
[G3 Accessories] iazybandit:
Or just wait another week or so for PMA wireless charging sticker chips.

different back plate

So say i have a d850. But my back plate is one that supports qi like a T-Mobile back plate. That won't work?

---------- Post added at 10:33 AM ---------- Previous post was at 10:05 AM ----------

I paid 4.99 for a T-Mobile backplate with nfc for my d850 from eBay.
[G3 Accessories] Pilz:
Qi will not work on the Att model using the back cover. The NFC will still work but no qi.
[G3 Accessories] asbiugyybsad:
I wonder if qi would work if i sacrifice my micro usb with a universal micro usb Qi charge receiver that uses a micro usb slot

I rather lose the micro usb

I bought a qi pad from ebay for 8 AUD, and it works pretty well :) dont spend too much money on pads...
[G3 Accessories] DonS:
Anyone tried the PMA + NFC stickers from Amazon

I see there are now a couple of PMA + NFC stickers to replace the NFC only sticker on the back cover of the AT&T G3 listed on Amazon.

Has anyone tried these? They are around $19 - $23. A new back with the stickers already installed is $39.95.

My only concern would be the bulge factor. I've seen the posts of people taking the stickers off the LG circle case for the D850 and put them onto the stock back and there was a bulge from the metal disk. I can buy one of the PMA + NFC stickers for around $20 and the Powermat charging cradle for about $10. So for $30 I could have wireless charging. I just don't want the back to bulge.
[G3 Accessories] AllstarE4:
It will bulge no matter what. The center magnet causes it to bulge. I, as well as a couple others, drilled a hole in the back plate for the magnet to sit in and it almost eliminates the bulge. You can cover it up with a skin or sticker or just do like me and keep a case on. After the modification I have no problem charging through my Diztronic tpu case.

I am using the $39.95 back plate from Amazon.

Edit: I think the price has dropped to $30 or lower.
[G3 Accessories] meladori30:
I got the sticker chip from Amazon

So I got the case with the sticker chip for PMA already installed. NFC works fine but unless I remove the sticker, hold in in place on the contacts and try the powermat it will not charge at all. Not even through a thin tape without any cover. It only works if I hold it and place it directly to the mat. The seller has sent me a new chip to try that will arrive tomorrow so we shall see if it was just a bad chip or what. I spent a lot of time trying to get this to work it was making me nuts! :mad: I went as far as to cut a hole out of the back of the stock plate to where the whole sticker showed and only left enough space to tape the edges in place still won't do anything. I'll update on the new one once I get it tomorrow
[G3 Accessories] messerchmidt:
so http://www.ebay.com/itm/LG-G3-D851-...arging-/301507442968?var=&hash=item46333e7918

will not enable qi on the att (rogers/cdn) version of the g3?
[G3 Accessories] the - man:
Ok so I understand that PMA and Qi are not cross compatible. What I don't understand is why I can't just slap a Qi sticker on the back of my phone and have it work even though the phone is on Rogers (I understand Rogers used PMA). Isn't there just some wattage going though the pins in the back and I can just slap on whatever sticker?

Hopefully you can clear this up for me, as I litteraly made an account on XDA just to ask this question.
[G3 Accessories] Pilz:
If the Qi 'sticker' plugs into your USB port then yes it will work just fine.
[G3 Accessories] the - man:
Ok that makes sense, so then the little pins, on the back of the LG G3 (2 for wireless charging, and 2 for NFC), are those pins for wireless charging connected directly to the usb port, or is there some sort of communication that happens to make sure that I don't put a Qi sticker on the phone that is only PMA compatible? If those pins are directly connected to the usb port, then how could AT&T and ROGERS (Canadian carriers) make sure we stick with PMA?

Thanks already for your help, just hoping I can clear up the issue on why I can't by a Qi back for my LG G3, on ROGERS.
[G3 Accessories] Pilz:
There pins on the back plate go through a different set of circuits (layman's explanation) than the standard mircroUSB port. They cannot stop you from using a Qi enabled sticker that plugs into your USB port, but they can stop you from using a back panel with Qi over the pins.
[G3 Accessories] awtryau89:
No, I paid $40 and it just arrived. The problem is it does not work. The pins line up perfectly but it will not charge at all on my Nokia DT-900. I have no problems with a Galaxy S5 Qi back. I am wondering if this is PMA. I am going to have to check with the seller on eBay. I have 2 Qi chargers but do not mind grabbing a powermat to test.
[G3 Accessories] Pilz:
No I bought a white back panel cod 40 and a black one to put the qi in for 27 so no it wasn't 140. (I have a black G3)

Because it clearly shows its qi in the add and I confirmed with the seller.
[G3 Accessories] bigdbag:
I was afraid of this. I ordered the QI cover as well. This does not bode well.
[G3 Accessories] Pilz:
Well if I had the white g3 it would only cost 40, but I didn't want a white back on a black phone so I got both. I just hate the Att logo on my phone but it was cheaper than buying another Korean model so I can deal with it by replacing it.
[G3 Accessories] bigdbag:
No I just meant that if the pins are for powermat only, then my purchase of the QI cover was a waste. More significantly, I'll have to buy a powermat and the Quickcircle case to pull out the powermat sticker.
[G3 Accessories] awtryau89:
I can say for sure its not the pins. They line up perfectly. The auction does not say Qi anywhere in the description. I think this is PMA. I will know later as I am going to purchase a PMA at Walmart or Staples so I can test.
[G3 Accessories] bigdbag:
Ah ok. Well. Damn. I already ordered a QI charger. I guess now I have to look for a portable powermat charger... What is life.
[G3 Accessories] RED ZMAN:
I'm glad there are others that will do the WalMart rental to test things like I do. Amazon Prime is great for that too. LOL
[G3 Accessories] Pilz:
I'll let you know I just got it so we will see.
[G3 Accessories] Lorimere:
Oh crap. So it's not just a qi or pma back? You saying AT&T baked pma into the phone itself and got rid of qi?
[G3 Accessories] jerflash:
Ya I really want to know. I'm getting this am my work phone and I already have a nexus 5 and really love the wireless charging. Have many chargers already lol
[G3 Accessories] Pilz:
Well it doesn't work on my Nokia dt910 that I use for my n7 but the contacts and thickness are the same layout as the d855 that I compared it to. I think only the q circle case from Att for the power mat and the backs are from the d855. I'm not entirely sure any ideas on how to check? I don't have a power Mar only a qi charger but I have heard its picky about what ones it likes.
[G3 Accessories] Charsher47:
Damn, so are you saying even if we got D855 backs it won't work and it's looking like we have to use pma?
[G3 Accessories] Pilz:
It looks identical but I don't know. I don't think there are PWA backs besides the Att qi case because they are the a partner for PWA. The back was not a carrier exclusive so it should be qi like all of the other LG products because LG backs qi and not PWA with the exception if some carrier merchandise as mentioned above. There is no reason. Why it shouldn't work but my charger could just be picky.(even though it works for others) qi has always been finiky.

EDIT:

I messaged the seller again to confirm that it is infact qi rather than PWA. I will update the post with what he or she says.
[G3 Accessories] Lorimere:
This would totally suck. there are no pma accessorys. no car docks, nothing. I could live with pma for home and office charging. But lack of any pma car docks bites ass.
[G3 Accessories] Pilz:
Here it is, I ordered another wireless qi charger to double check if it will work or not. I had it overnighted so it will be here tomorrow. I'll post an update with the results.
[G3 Accessories] Lorimere:
The white one looks like the one I have on order (should be here wednesday). But the one I ordered had a picture with the verizon logo on it. So you don't get any lights on the charger or anything to even suggest it sees it?
[G3 Accessories] Pilz:
That's correct but I ordered a flat qi charger to double check.
[G3 Accessories] awtryau89:
Good to know I'm not losing my mind. I have the same back and it doesn't work with the Nokia. I couldn't find a PMA tonight so I will look in some more places tomorrow. I have tested it every way possible with the Nokia and it just will not even light up.
[G3 Accessories] Pilz:
I'm having the same issue. Let me know if you find a power mat. I'm still awaiting the sellers response.

Other threads have stated the g3 is very picky when it comes to qi chargers in general I hope this is the case because its defiantly a OEM back.
[G3 Accessories] Pilz:
Update:

My other qi charger was just delivered and I can confirm that it does NOT work. I also tried it with a power mat at att and it still doesn't work. Is it possible that its defective, or that AT&T has something in the phones software preventing qi from working? I still haven't heard back from the seller, but I will most likely file a claim because it does not work. I'm rather disappointed, but atleast I used paypal.
[G3 Accessories] dwd3885:
The back u have might not work. I wish LG would come out and offer replacement backs.
[G3 Accessories] awtryau89:
Same experience here. It definitely does not work with any type of charger. I would not put it past AT&T but the only place I could think of them doing this would be in the Circle Case menus. I checked those menus and there is not a way to turn on or off wireless charging. I don't think they could actually prevent you from wirelessly charging in the firmware. Its just some electrical contacts and those would not know if you are using PMA or Qi. The one thing I thought of was AT&T possibly having a different pin setup. But the stock battery cover uses the bottom 2 pins for NFC so that's out as well. Most likely we just got defective backplates.

I filed for a return as well. Let me know if you hear back from the seller. I emailed them about the back yesterday as well and have not heard from them. I am withholding feedback just in case I need to use negative feedback as leverage.
[G3 Accessories] Pilz:
He did return a message and said to send it back at my own cost. Its unfortunate that he isn't cooperative (I sent a dozen messages and got a single reply). He also said he guarantees its OEM but that doesn't mean its not defective.
[G3 Accessories] Lorimere:
well mine will be here this week. But I guess it isn't going to work.

Guess I'll just keep it, never know when I might want to rock a white phone.
[G3 Accessories] tomdog22:
i'm also one of those people that purchased this back thinking i would be able to qi charge it. damn! i will be following this thread hoping something positive comes from all this!
[G3 Accessories] Pilz:
I wonder if its actually a defective item, but with this many people facing the same issue its not likely. I wonder if these were factory rejects or if they are not meant to work.
[G3 Accessories] Forest007:
I purchased one of the charging backs from the same ebay seller too. I'm waiting to receive it. I will be following this thread also....
[G3 Accessories] Pilz:
His communication is terrible, so if you have an issue good luck getting a response. I have had 3 different guys respond to my messages of now with very brief statements that do little to help out.
[G3 Accessories] Forest007:
Ok. It's been shipped already so I should be receiving it soon.
[G3 Accessories] awtryau89:
I got a response tonight. Here it is:

Hi, sorry for the late response, and we are very sorry to hear the problem from you. In this case, you can return it to our return department for inspection and test. Below you will find your RMA number for the return. You will need to write down the RMA number as well as your eBay ID on a piece of paper and include it in the return package. Also, please write the RMA number on the outside of your returning package, and pack the package well to void any damages during the shipment.

Looks like I shouldn't have a issue getting a refund. I hope it doesn't take forever though.
[G3 Accessories] asics10:
Thought I'd give it a go, hope to have qi working within my return time line.

So I took the charging coil out of my galaxy s3, taped it to my qi charger, and placed the contacts onto the pickups on the back of the g3 .... And nothing.

I understand this is not an official g3 qi receiver, but I thought it would have worked. So either you need an official back cover OR I'm thinking att crippled any wireless charging that is not pma.
[G3 Accessories] Pilz:
I hope there is a way to fix this. I want to hope that we can use qi for the us models but it not looking likely right now.
[G3 Accessories] awtryau89:
I put this in my other thread as well.

Well I tried something else today. I was thinking if AT&T had it locked down to only work with the Circle Case, it might be able to be tricked into thinking it was on. I put the wireless charging back on the phone and used a magnet to activate the screen like the Circle Case was on the phone. Even when doing this, the phone will not charge on the Qi charging pad. So if it is locked down by AT&T, there may be some other magic I'm missing. As of now though, I am betting I have a back that isn't functioning properly. I have a RMA to send it back but I think I'll wait a few days to see if others get theirs and if they also do not work. If no one else's work, I just do not think there could be that many malfunctioning backs.

One other thing, has anyone tried NFC with the back? Since the coil in the Qi charging back has NFC as well, this may give us an idea. If NFC works, something is up with AT&T.
[G3 Accessories] Pilz:
It works just fine when I used it for tap and pay. This was before I tested the qi on it. I used it with isis and android beam without issues.
[G3 Accessories] Forest007:
I'm going to try the wireless charging back (when I receive it) with the Qi charging mats that I have. I have the Samsung wireless charging pad mini and the Tylt VU.
[G3 Accessories] awtryau89:
Well if that's the case I may keep this back for a bit longer. I think AT&T has something locked on our phones.
[G3 Accessories] Pilz:
Has anyone with a different model such as the d851 tried one of these?
[G3 Accessories] jerflash:
this is what i want to know was well....
[G3 Accessories] Lorimere:
Haven't got mine yet. But from what it looks like. I can't imagine every back is bad. I just think AT&T version is only going to work with pma. Makes me sad.

In other news. Looks like my PMA quick circle case will be here tomorrow. But I have not got any powermat accessories to test it with.
