If one has good soldering skills

 

[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.

Nice pics! That's a better solder job than I could do! Hope you get it figured out.

what is the tape thing with 2 copper wires for? I thought it was for wireless charging, is it like NFC?

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.

That's not a practical solution for most people. Hopefully there will be some form of a solution for everyone else.

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.

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?

Buy the TMobile one because it has qi and an unlocked BL. You will get LTE in ATT as far as I know.

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?

I paid 4.99 for a T-Mobile backplate with nfc for my d850 from eBay.

Qi will not work on the Att model using the back cover. The NFC will still work but no qi.

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...

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.

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.

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! 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
