AT&T warranty replacements with no wireless charging - G4 Q&A, Help & Troubleshooting

I got a Qi sticker and some pucks from Amazon for my original G4, and the wireless charging worked fine. Then it bootlooped, so I got a replacement (they sent me a refurb or course) and on the new phone, wireless charging just refuses to work at all. I called back to complain about that and they sent me another refurb, and wireless charging isn't working on this one either. I haven't changed anything at all but the phone itself. They had me keep my back with the sticker still intact, and of course my same chargers. Anyone else have this issue? I guess I'll call them back again, I'm just tired of fighting with them for yet another refurb phone. The only thing I noticed is a weird clicking noise when I put the phone on the puck. I'm not sure if it did that before or not.

Are there wireless charging contacts on the phone main body? Some OEM versions don't have wireless charging.
If the contacts are there, you could try slipping some paper or electrical tape under the contact pad on the back to raise it a little bit to make better contact. If that does not work maybe the sticker needs to be repositioned to align the contacts. Look carefully at the contact pads on the back - you should be able to see where the metal phone contacts are pressing against it. Everything has to be positioned just right to get both charging and NFC to work...

Yes, they're there. They were there on the first phone and the 2 after. I've tried manipulating the Qi sticker, but the exact same sticker worked fine on the first phone, and then not at all on the next 2. I might try a new sticker, but it's just strange.

I've got a similar issue, but with mine, they changed the mainboard and returned it. Is yours a 602 serial # device or are the refurb units which they sent you 5xx? If 602, I'm curious if part of the "fix" involved completely removing the wireless charging capability. I even tried peeling off the Qi sticker and carefully positioning it over the contacts, then putting the cover back on, just in case maybe it was out of alignment - crazy thought since it worked fine before the bootloop/warranty issue. But that made no difference.

Mine's a 601 serial. I contacted LG directly and they just said "Oh that device doesn't do Qi you need to get the other one" but could never answer why the other one worked fine..

Try cnn.cn but i think you will find only the whole micro usb port and not the flex cable alone
I have tried 12 replacement parts from ebay for an i717 and they ALL have no service after putting them in. but the original one that doesn't charge still gets service fine...

Yes, the AT&T version and the International version have different radios, and the micro USB port is connected to them. They are NOT interchangeable.
i717 ≠ GT-N7000
Any tips anyone?
Hi, I just want to revive this thread rather than start a new one.
I am gonna swap my my usb charging port for a one I bought on eBay. Does anyone have any tips I should know about that you can tell me?
I'm going by this youtube video. this is all I got and of course I'm kinda scared.:crying:
Thanks. Will check back later.
Easy to do, but will cause other issues
Hi. I too have just brought a note with this problem.
The replacement is easy, remove battery cover, battery sim etc. Take out the screws, use something thin to pries the edge off. Its the lip below the screen level though. After that, 3 more screws for the bottom section, then take out the one screw in the thin motherboard piece. Slide out the old flex, slide in the new one, re assemble.
The biggest problem is that youll most likely lose 80 % of your reception from it. When the phone is open, try to see if there is any corrosion behind your USB port, if there is clean it and try it. I did that as im sending my ebay one back for a replacement, Now my old one seems to be working, but for how long, i dont know.

I bought a battery charger and extra battery. I bought the brand Hyperion but I've heard there are better brands. Anyway, I don't charge my phone any more... I just swap batteries now. One is always on the charger and one in the phone. It works fantastically and further, the phone always has a charge. When I want to swap files I remove the card and put it in the PC. Works really good.
If you are on about the daughter board I got one of Amazon for£10 took less than 10 mins to fit and have had no problems. Came In OEM packaging
Any questions feel free to PM

It's 10 black screws on the back & 5 white to take there cover of over the daughter board. No need to undo a mother board screw whats this about losing 80%signal?
That's rubbish, Sir! Mine is on5 bars H+ and has been sincei did it. As there is a new mix. Too the sound is better, IMO

Bought mine off ebay worked 100%, signal is still the same, nothing happens to signal. But you have to buy the whole board. Mine didnt come with a wee microphone bit so i took off my old one, stuck the sticky bit within the square part and put the rubber part in the cover and screwed it on. Everything working fine.

My usb port is busted so am replacing that board too. However, I've bought two off ebay and both have had problems. First one fixed the charging issue but didn't give me any reception (well one bar now and then) and the second gave me signal but had a busted micro usb port. EBay can be so fustrating sometimes!!

I have just fitted my 3rd replacement board and loose most of my signal after fitting it. My original board gives me full signal but intermittent charging. :crying:
Do all N7000 use the same board or does country intended for make a difference? My note is an International phone made for Hong Kong.

To be honest I still haven't got a perfect replacement yet but one that is at least functional (get werid noises during phone calls - not on my end but on whoever is calling me).
You do have to make sure you get the correct board though. If you look on the original board it should have some writing in gold near the top. Mine said Rev 1.0 so I got replacements which were rev 1.0 too. Apparently there are other revisions (although I didn't come across any others).

USB Port/Daughterboard Replacement

Some how (isn't that what they all say) got water in my GNex USB Port which caused the port to fry once charger was plugged in. Phone still fully functions as normal, just can't charge it. After pricing out a few options, I've decided to replace the part myself. Should everything go well, this should save me at least $35.
Just wondering if anyone else here as had to do this, would love to hear how it went for you. I'm currently waiting for the part to be shipped to me.
There's been quite a few people (not me so far) who've had to change their usb ports because they failed (stopped charging). There's several threads on how to do it, I've not bookmarked them but search would probably turn them up.
Should be pretty simple if the charging port is on a daughterboard and not on the main PCB. It's pretty easy to remove the lcd/digitizer + mainboard from the housing, and if it's just a daughterboard you should be able to disconnect the old part from the connector and attach the new one.
Thanks for the replies! ifixit.com actually has a detailed step by step, just wanted to see if anyone here ran into any issues while doing it or not.

Its fairly easy to replace the USB board if done with care and proper tools. A word of advice, when you remove the back cover ( the step after removing screws) pay attention to not drop the rubber buttons..... they are hard to find once they hit the floor . Anything than that, just do it with love and you will do fine
Success! Time to put the Aria back in the closet!
I take that back, the microphone (which is part of the usb port board) on the new board does not work. Attempted to make a phone call and they could not hear me. Used a voice recording app and got nothing. Looks like I'll be getting another replacement.
I've got to hand it to Wholesale Gadget Parts, Inc out of Oklahoma. That's saying a lot coming from a Texan, we usually aren't too fond of Oklahoma. As stated the other day, the replacement board I got had a faulty microphone. Called WGP, no questions asked shipped me a new one and got it within 48 hours. My GNex is now back to fully functioning order!

[Q] Wireless (Qi) Charging (and GPS) experiences?

Nothing is ever easy, is it?
I bought a pair of BRC 550's off of Amazon - one for my phone, one for the phone I intend to give my wife (which had to be sent back to the Ebay seller because the condition was misrepresented.)
I picked up a few Nokia DT-900's directly from AT&T. ($24.50 each, but then 25% off if you buy 3 accessories - great deal, even with tax.)
The Qi charging works great, although I can hear the high-frequency sound it gives off.....
But today I noticed Waze and Google Maps aren't getting a GPS lock. I first wondered if it was my fresh chilly CM10.2 (now with ringtone!) install. So I switched back to 10.1 and loaded up "GPS Status & Toolbox."
It has nothing to do with 4.3. Then I thought maybe I skooched something when I replaced my USB port earlier today. I popped the back off to start disassembly to check connections but before I got out the Torx driver, I thought to try to stock back. BAM! GPS lock.
Switched back to the Qi back. No lock. Tried the OTHER Qi back. No lock.
The "antenna" bits are a bit different in the Qi back vs. the stock back. I wonder if that's the issue. Does anybody know which one is for GPS?
I guess I should check for cell signal differences, too.
Grrr. Palm had this poop down years ago. Maybe I go back to trying to modify the stock back with a Palm coil, return the Qi backs and Ebay the DT-900s. Cheaper and cases will fit better than with the Qi back.
Anybody have any thoughts? Common or different experiences?
Never mind.
The style of the GPS antenna on the Qi back is different; it's a metallish strip pinned down across the center by a thing plastic strip. (I think.)
By flexing the wings up a bit, I now get signal. I guess they weren't quite touching the contact pads on the circuit board.

Replacing the charging port

Hey all,
I just replaced the charging port on my m8 and wanted to let people know it is straight forward. My port got corroded and was shorting out, melting the adapter and not charging the phone. I sent it in hoping for warranty, but the replacement quote was $400! (due to S-off they "had" to replace the entire motherboard). The phone has a separate pcb with the micro usb charge port and headphone input.
example:
http://www.witrigs.com/media/catalo...a71cb48e3d52cb890e76f9e6353/1/0/109063-01.jpg
To remove this board you need to do a few easy things:
1) disconnect the ribbon and remove the insulating tape (to reattach to new part)
2) unsnap the small white power cable
3) loosen the screw on the motherboard near the headphone input. This is clamping down the assembly a bit
tools required:
phillips 00
t5 torx bit
spudger/guitar picks
I would recommend prying the phone out of the frame starting from the bottom. I started from the top and bent the thin strip of aluminum above the sim slot when prying it out.
Also, you can pry the bracket/spring off the top of the old usb port to give the new one a tight fit if your replacement didnt come with it (like mine)
Lastly, just note that power button fell out as soon as I pried the frame apart from the guts. This made it a bit of a pain to reassemble - just be sure to reassemble with the top in first. That will keep the power button in place.
The replacement part cost me $30, so it was definitely worth it! phone now works great.

Hey there. Interesting to know that you replaced it all your self . Did you put everything back perfectly ? I mean the display being aligned properly to the body, the speaker grills being flushed with the body; ? Weird to ask, but did you damage anything while doing it all yourself ? Like the screen scratches, or something else ? Sorry, for asking these... Thanks in advance :good:

I haven't re-glued the speaker covers back on yet so I dont know if they will be perfectly flush or not, although they still look flat so I think it will look good.
The only damage is a slight bend in the frame on the screen side of the sim tray slot. The metal is thin, and I pried against it to get the hardware out of the frame. That is why I recommended to start from the bottom when separating the two. Doing this should allow others to avoid this problem. It is slight, maybe 1/4mm gap where it used to be flush along the side of the screen above the sim tray.
Otherwise everything was smooth. The screen/frame etc are still mint.

Cool, you've done it like a pro then. :good: .Any picture describing the damage would be helpful, if you can provide. Is the display mint ? No scuffs/scratches on it ? But, my speaker grills were damaged onto the edges after the repair was carried out. Does yours show the same sign ? I don't mean the flatness of the grills, but the damage that should be done, while prying out the grills. A picture showing your damage would be helpful to me. I could do the same, if you insist. Thanks ! :good:
Mine is busted. But I cannot find the PCB. The link in the op is dead.
Any ideas?

I actually got one off eBay for $17.21. Works perfectly.
Just wondering....
Sounds like you were able to avoid some steps in the teardown guide, if I recall it was damn near a total disassemble. Do you have a lot of experience with phones? I want to fix mine, but don't need a tedious project right now. If I repair mine I'd like to put a mini USB in place of the micro if possible, I've seen too many damaged micro usb to trust or like them. As for the speaker grills, if you're picky buy replacements, they're cheap.

My HTC M8's main call microphone has stopped working, and through searches on Google it seems that perhaps that this mic (first mic, non-speakerphone mic) is built into the charging port. Is this the case? I cannot find anything that explicitly says this, and I'd love to get the phone back in working condition.

I called HTC, the mic is on the USB port, although you should make sure that it's not a software issue first. There are several threads on the internet easily found through Google which discuss doing a factory reset to resolve this if it turns out to be a software problem.
Thanks for your reply. I did a factory reset when I got the phone but it still doesn't work. Does that mean it's not a software problem and that if I replace the usb it should work?

No, but from what I've studied about it, it should work. Feel free to contact HTC, they actually have a live chat available somewhere on their website. Good luck to you.
Very interesting, I contacted htc and we went through diagnostics together and the rep said that I have to send it in. I asked him if the mic was on the usb assembly and he said that it wasn't and rather it was on the motherboard, and I clarified that we were talking about the primary mic which is located near the usb port. Confusing bec everywhere I saw online said that the mic is on the usb assembly. Go figure!

What did you end up doing? Did you discover if it was on the motherboard or the part with the USB port? I've waited a while to repair mine for other reasons, and I am now prepared to fix it. Any information would be helpful.
Just a few notes on my own experience.
I replaced the screen in my friend's M8 a few months ago. Seemed like everything went ok, except after I got done, the mic didn't work anymore. This is strange because it worked fine before, and all I did was remove/replace the circuit board in the process (yes, the small one at the bottom with the uUSB port). However, the upper rear microphone was still working I believe, because people on the other end of the line could still hear if the phone was put into speakerphone mode. I don't know why it would stop working all of a sudden.... Ran the HTC audio test using *#*#3424*#* to confirm main mic wasn't working and that the aux rear mic was.
Fast forward to this week, with my own M8. The uUSB connector was going bad, and I was having trouble charging, so I figured it was time to replace that circuit board. Ordered a new one and replaced, but when I got it back together, the USB port was fine of course, but my mic wasn't working now, just like my friends! On top of that, the headphone jack didn't work at all. Most likely the "cable inserted" signal wasn't getting back up to the motherboard, but didn't check. So pissed off. Also, the new board I got didn't have the bottom left RF connector/circuitry populated. Thinking from research that it might be for the GPS? I should have tested when the board was in there, but didn't. Fixed a bad solder joint on the original board's uUSB connector, which helped, but still charging is a bit messed up. I'd rather have a working mic and headphone jack and have to play with the cable to get to charge for a while until I get another board (from another supplier, jerks).
Yes, the mic is the small chip on the very left side of the board. It has a hole underneath the chip, going through the board and to the front face to receive the acoustics.
I don't know why the mic not working is so common after an HTC One M8 tear down, as it seems many others are having the same issue. One theory I have is that pulling the circuit board from the motherboard while power is still applied (not unplugging the battery first) might be jacking the microphone somehow. Just a theory, but I'd recommend to be safe that anyone replacing the board should unplug the battery cable before replacing the USB/mic circuit board.
I'd just like to chime in to say that I've read about some people having problems with the mic not working after replacing the USB board. From what I understand, there are two different versions of it, and replacing it with the wrong one can cause that very issue. You should look into it.

Mic broken after USB repair
Old thread but I have the same problem. Replaced USB board and now my mic does not work. However I am pretty certain I did order the correct board (had 2x connectors for my Verizon HTC m8). And my microphone jack work great which others indicate is often broken along with the mic. Anyone have any workarounds?

Connection pins in the backcover

On the inside of the backcover there are 2 little copper pins. Can anyone tell me what they do? Or is this just a way to detect that the back is attached or maybe NFC or wireless charging?
AFAIK, the lower two pins are for NFC.
The remaining two upper pins are for wireless charging. (need compatible back covers)
I bought Verizon G4 yesterday at Best Buy, most importantly for the camera and removable battery, but also because of wireless charging, which I've been using for about a year on my Moto G.
I had to add the coil receiver to the Moto G, and it does a very good job of keeping the phone charged. It's slow, but I work at a desk at home all day, so the phone sits on the charging puck, and speed is not an essential requirement.
I was aware before buying the LG G4 that the back had to be swapped out for a "receiver" back, but I was dismayed to learn that there doesn't seem to be such a thing available, at least here in the U.S. The only charging device available is the circle device, and that's not what I want.
When I got the phone home, I pulled the receiver out of the Moto G and slapped it into the LG G4 and tried to charge the phone. I immediately got a note saying that charging had stopped, and the add-on receiver was incompatible with LG.
So much for that idea. Anybody have any thought on anything other than the circle case??

A few people on other xda threads are ordering some from aliexpress.com.
http://www.aliexpress.com/item/G4-W...ireless-Charger-Battery-Back/32359379615.html
or
http://www.aliexpress.com/item/Wire...E9aQ2fUoTXld0i5X8eQSvhtz-yu6&cn=9263&cv=15091

I pinged the link you gave, but it does not list my phone, which is a VS986. I'll have to be more clear on which contacts do, or do not line up with those on the phone.

The first link says Verizon on it. while it does not specify the VS986, it looks like it might work. That seller also has a video for their QI charging chip install.

Looks Good, I Found Similar On eBay

Thanks, Wooz, that looks like it will work on the VS986, but this outfit will not take PayPal, but requires a credit/debit card, and I didn't feel comfortable with anything other than PP, so I did not order from them.
I found a new listing on eBay, and ordered from that outfit, also of course in China.
I don't claim any expertise here, but it seems that the sticker needs to pick up the BOTTOM TWO contacts of the four shown to the right side of the battery. The one I purchased ($8.80, free shipping with PayPal) seems to do that. This outfit also claims its sticker contains a chip for NFC, which I've never used and don't feel is a major item just at the moment. However NFC might turn out to be helpful later, although I'm completely in the dark about its methodology.
The link I bought from is [email protected]
I'll add to this info after I receive the sticker and fumble it into the phone, although probably not as adroitly as the guy in the video.
