NFC not working - Nexus 5 Q&A, Help & Troubleshooting

Hi everyone,
I recently bought a used Nexus 5 from Glyde. Glyde requires purchasers to test the phone and let them know if it is in the condition the seller had advertised within 3 days. I had ordered an NFC tag that didn't arrive in time to test NFC before verifying that the phone was in excellent condition, which is how it was advertised. Everything else on the phone works flawlessly but, once the NFC tag arrived, I found that NFC doesn't work. I haven't tried wireless charging but am assuming that probably doesn't work either as the NFC and wireless charging are controlled by the same module on the motherboard. The model number of the controller is BCM20793M.
I tried a bit of troubleshooting. I took the phone apart, removed the NFC controller and had a look at the connection. All of the pins on the ribbon cable seem to be making contact with the pins in the socket on the mobo but still no NFC. I've done a factory reset and sideloaded Lollipop the day it was released. Unfortunately, NFC still doesn't work. I'm almost certain that it's just a defective controller. I called LG. Tech support had no idea what I was talking about when I asked for a replacement Broadcom NFC controller and referred me to the parts department. The parts department doesn't sell anything but batteries and chargers. They asked me to send my phone to them for 5-7 days. I'd like to avoid that. So, I set out on a search for one of these modules and can't find one anywhere. Does anyone know where I can find one of these for sale?
My wife also got a Nexus 5 and the NFC works. If it comes to it, I'll just swap the NFC controllers in mine and my wife's phone as she's told me she doesn't need NFC. If I can just buy a new controller and have two phones with working NFC, I'd rather go that route.
Thanks,
Matt

Tilt2/Rhodium repair advise

I have damage to the "mini" USB port on my tilt2. It occured back in October as someone tried to pull it off the USB cord in an attempt to steal it. The phone worked fine and I could charge and sync but all the audio and video pins were pulled out. I decided to not mess with it until now, since the charging is now intermintent and I had to postition the phone, yesterday it stopped charging and I saw the little pin fall out from the USB plug. I found a local place (Houston, TX) called Fullbars http://www.fullbarscellrepair.com/Repairs.html which is a franchise with stores in NM, and Ca. The guy said he could repair it but he had to order the part. He wanted me to sign a waiver, in essence he said that in order to remove the previous USB port he will have to heat up the motherboard and did not want to be responsible for any damage from the heat he applies. He said this is a standard waiver he uses for all similar repairs. I did not sign it and said that I will think about it if he is willing to order the part, which he will do and he would be able to get it in 2-3 days. Does anyone know if this is a standard procedure to remove the mini USB port on these phones? I know that repairs are operator dependant, but has anyone had experience with these stores? What would you suggest?
I called HTC and they want to have the phone mailed somewhere and they would keep it for 2-6 weeks. Any advice would be appreciated.

USonic and adapter issues

Hey everyone,
I'm writing to you all because I could use some some help or diagnosis because I really don't know what's wrong here.
Okay so first thing first, I've been using this phone for 4 months now, and so far, I like it.
So I've been using the USonic for listening to my music. Except that since a couple weeks, the USonic has been acting weird.
One side isn't working correctly anymore, the sound is weird (not loud and.. just not natural) and the microphone isn't working.
But fortunately, the sound is working decently if I plug them on the other side (although it doesn't sound as loud as it used to..)
One time, both sides weren't working at all (Accessory not supported in the settings) but after a cleanup of the USB port, it went back to the "one side only is working"
Okay so I thought that MAYBE my USonic were just half dead.
So I decided to use the adapter (which I barely used)
It sounded like it was working correctly but then I realized that while I was playing music (or even when they're just plugged in), the adapter disconnected/reconnected (the earphones icon disappeared/reappeared and so is the warning message that says that the adapter will draw power)
I noticed that it occurs when I touch the adapter a little bit, so it can work if I don't move at all, but that's definitely not possible given that I mainly listen to music when I'm commuting.
For instance, putting the phone in my pocket and walking would trigger the issue.
So now I don't know, either I'm very unlucky with my accessories, either something's messed up with my USB port.
I originally wanted to send it to HTC for repairs but before doing that, I decided to be honest with them and told them that I unlocked the bootloader, so I wanted to know whether it would void my guaranty or not. And apparently, it does (in France)
So I'm not sure if I want to send it to repairs and pay a lot (for an issue that has nothing to do with unlocking the bootloader)
I also could buy a new adapter on HTC France but it pains the living hell of me to pay 16€ of shipping. It's just unacceptable.
So here I am, clueless on what do to. So I'm requesting your help, dear community.
What can I do? I did a factory reset already, I did go back to a RUU already.
I did clean the USB port and it looks clean but if you have any effective method on how to clean it, I'd be happy to hear about it.
If you know any place where I can buy a working adapter (which seems complicated) for a decent price.
Unfortunately, I can't buy Google pixels ones since Google doesn't sell anything in France.
Thank you very much for reading my misfortunes and I thank you for any help,
EDIT: Forgot to add that I have absolutely no problem with charging or transferring data with the USB cable.
Same problems
I have similar issues with mine (unlocked US version). My USonic headphones, charging cables and data transfer all work fine. When I first got the phone I had no problems with the included adapter, I even bought 2 more to keep as extras and they all worked fine.
About a month ago I plugged in the aux cable in my car and the sound was coming out of the phone, there was no headphone icon and it was not recognizing the adapter. Later I tested out the other adapters with no success. My wife has a U11 as well, so I tested all of the HTC adapters on hers with no problems which ruled out that my adapters were faulty.
I did a support chat with HTC who of course suggested that I factory reset my phone, which didnt work. Then they suggested I do a RUU, which also didn't solve the problem. The port is clean, no dust or lint.
On the google play store reviews for the "Audio Jack Toolkit" app many people are reporting the same issue. I just haven't had time to send the phone in for repairs at the moment.
You're lucky that I am seeing your post.
I'm in France as well and I have experience with HTC support team & repair center. But I don't have any problem with USB C connection in no matter what situation on my HTC 10 & U11.
I suspect that some pins of your USB C port on the U11 is not working well, so that you can't listening to music well but meanwhile you can charge it normally.
To test if it's a problem of the adapter you bought, just plug the adapter to any other USB C port phone, to see if it's working. (Yes, HTC headphone jack adapter works for most other non-HTC phones with USB C)
And, I'd say you should grab your chance to send the machine for repair if it's really a hardware (USB C port) issue. Even that you removed the warranty, but you should try. Because it's Cordon electronics who repairs the HTC phones in France, not HTC official staffs. Even if they found you don't have your warranty anymore, you should also be able to pay them to repair (the warranty just covers the repair fee, not means HTC strictly refuses to repair). You can't just live with it or spend another 800 euros or more to get a Pixel 2.
Anyway, you're welcome to reach me out on PM so that we may talk on twitter or other platforms. XDA is good for sharing developer stuffs but not for friendly chatting.

Little update. I sent my phone to Cordon electronics with both accessories.
I just received it today and not only they only gave me a new pair of HTC USonic (I did put the adapter on my package and yet I received nothing from them) but the best thing is that my screen is now cracked!! Wow.
I don't know how I'll ever prove that I sent it without it being cracked but I feel that I'm pretty much screwed.
I know that this is independent from HTC but honestly I lost faith in the company :/

WTF...Send email to HTC support with photos.
That's just ridiculous...
Keep me updated, I'm HTC elevate & ambassador, I can't just let things like this happens. If you want, send me a PM with all the details/photos, I'll see what I can do.
You shouldn't have to do this but I suggest recording everything you do from now. Record yourself boxing up the phone, etc. It's something I always do after horror stories of repair centres returning damaged phones.
Audio Router.apk is the solution
I just had the same issue with my Usonic headphones. They would only work if I gently pushed them in and any movement caused them to disconnect. Charging worked fine. I used a needle and cleaned out all of the dust and pocket lint from my USB port and now they are working perfectly!

Using LG G5 on Ethernet network

Hello.
I recently came into possession of an LG G5 Android phone, T-Mobile variant H830. I was planning to use it for software development, and I was wondering if there's a way to get it to connect to the internet using my ADSL connection. I'm fairly new to the wonderful world of Android, so please bear with me.
I realize Wi-Fi is the path of least resistance... but it's not the best option in this particular house and I have a fine Ethernet network just sitting there waiting to be used. Also, my old Windows Phone (ducks) is able to use it just fine.
I have a USB type C hub (a Microsoft HD-500 display dock) and a small collection of USB to Ethernet adapters (Realtek RTL8153, ASIX AX8872B). Unfortunately, the LG G5 has no interest in recognizing any of them.
I've also played around with reverse tethering to my PC, but apparently it requires root access to even work, and even after that it doesn't even work very well.
Does anyone have any suggestions on how to make this work? Should I be looking into flashing LineageOS? Or maybe I just have the wrong phone?
Thanks.
Today's progress: I played with an app called ReverseTethering, which works by establishing a VPN connection to its host PC over an ADB-controlled USB pipe. Most apps seem fine with it. However, the Google Play Store insists on using Wi-Fi to download apps and won't recognize a reverse-tethered connection. It does resume in-process downloads over the connection, but won't initiate new ones. My conclusion is that this is an app bug, and that it is checking for Wi-Fi when it really should simply be checking for a valid connection.
There's an app called Fake Wifi that will apparently hack apps into thinking their connection is over Wi-Fi when it's not. However, this app needs a framework that requires a rooted device. So, back to square one.
(NB: I'd prefer not to root my device for security reasons.)
Today's progress: connecting a Sharkk UH-SKRJ11 (RealTek RTL8153 chipset) directly to the phone using a USB C-to-A adapter works. A couple of apps seem iffy about it, including the Google Maps offline downloader, but the Google Play Store and the LG updater work. So this is probably as good as it gets without major surgery.
This suggests that the problem was in fact the Microsoft HD-500 display dock. It would charge the phone, but the phone didn't seem to recognize it as a USB hub.
Does anyone have a suggestion for a USB Type C hub that works with this phone? Ideally I'd like to use Ethernet and charge at the same time.
Hello,
I work on the desktop team at a company and we started using Dell's DW-15 USB-C docks since Dell is phasing out the E-port. Out of curiosity, I plugged my phone into one a couple of months ago and everything but the display output works. We also have Dell 96NPS USB-C to Ethernet adapters that work fine with the G5.
I have this here.
Bought from eBay. Works on both G5 and V20. Should work on any phone that supports SlimPort.
I have connected it to the phone with display and various peripherals. Did not try ethernet dongle though.
I'm a bit puzzled that the Microsoft dock did not function right. I though that too was simply a display/slim-port design. Or maybe it's only the hub/otg functionality that's unavailable?
@askermk2000: thanks for the note. Any idea what the model number is on that device?
The Microsoft dock situation is quite odd. Before fully patching the OS (the phone arrived with the March security patch, I think) it wouldn't see anything at all on the dock (which has a Surface Ethernet Adapter aka RTL8153 plugged in). After patching, it suddenly started working, and working fine. Then after patching up to latest, it sort of half-works. It connects and data flows, but the phone pops a "Connecting" message for a minute every so often, as if it were pulling a new DHCP address or something. When connected directly to the Ethernet adapter, things work fine.
(And when I say fine, I mean mostly fine. Every now and then I plug in the adapter and nothing works. Disconnecting and reconnecting sometimes works. Changing USB connection settings sometimes works. Sometimes rebooting works. <shrug>)
@Keynesian
I'm sorry but there is not a single marking on that thing. A truly generic device.
That exact one seems to have become rare now. This looks like the successor, though it has one less usb port than mine.
Here's a listing of mine.
There are many generic types, with or without hdmi, one or more usb etc
One option with aluminum housing, 1 usb 1 hdmi and usb-c power input should cost no more than about $10
I think I got mine for around that (which is a more expensive model), but I got lucky and found a lonely expiring auction. Saved maybe $20
Weird about that dock of yours. Hopefully you'll have better experience with another one.
If I had an ethernet dongle I'd try to confirm if it works with or without the dock on my H850, but that could also depend on the type of chipset and driver used (and LG's flavor of the month it seems).
Just ordered one of these off Ebay. We'll see how it goes in a month:

Xperia XZ Premium Charging Issues

Hi All,
I'm hoping someone here can share their opinions.
Recently I've been having charging issues with my XZ Premium. Started a few weeks ago, with the charger plugged in, it would randomly stop and start charging.
Lately it's been getting much worse. I have tried different chargers, cables, adapters etc. The original Sony USB cable plugged into a wall charger, and my laptop. My Dell laptop USB-C (thunderbolt) wall charger, as well as my Dell external battery charger, as well as MicroUSB cables with a USB-C adapter.
Without touching the cables or moving anything, sometimes it'll start or stop charging randomly.
I personally think it's the phone's USB-C connector. I've tried to clean it using a damp wooden toothpick and got some dust out, but it didn't make any difference.
The phone is rooted, and is out of warranty anyways. I also have a lot of security features installed which would make it hard for a tech to troubleshoot (needs passwords etc to be shut down or rebooted) and I store some cryptocurrencies in wallets on my phone.
Is it worth taking it to a tech (I live in Japan, and don't speak much Japanese) or should I be looking at an upgrade? If so, what is the recommended phone from Sony currently? I honestly really like the XZ Premium, so I'm tempted just to buy another one if mine can't be easily fixed.
Thanks!
Bit of an update.
I managed to get my phone to charge using the original Sony USB -> USB-C cable, with an adapter plugged into the thunderbolt port on my laptop. Charging is still incredibly slow though. Also, I noticed when it hit 30% charge, it stopped accepting charge unless the phone is unlocked. If I hit the lock button, the charge light switches off. It switches on again when I unlock it.
*Small edit* It stopped charging again at 31%, despite being unlocked.
Wiggling the cable in the phone socket doesn't seem to effect whether it charges or not, which should rule out the connector in the phone. It has also not registered as a device on my laptop, despite being connected via the USB cable, which would mean it's not specifically a battery issue either, as there's no data connection being made.
So I'm starting to think it's a hardware issue.
I've ordered a new Xperia XZ Premium, because I really do love this phone, and the new XZ2 Premium doesn't seem like much of an upgrade to me apart from the camera, and slightly faster performance. And as much as I'd love to have wireless charging, moving the finger print sensor, and no 3.5mm audio output is a massive dealbreaker for me.
mine died like this, was on charge, started to say charghing/discharghing until he turned off and never came back.. under warranty they changed MoBo/2 stickers/components (??)/ 2 screw and now is back like new
Long term bump.
I bought a new replacement 8142 and have been using that successfully, and I decided to try and fix the charging issues on my old one.
I've just installed a brand new genuine battery, charging port, and power/vol/camera button connections.
The phone booted up fine, but it's STILL not charging at all. Any ideas? Motherboard maybe?

Maybe the flex cable isn't working
have only just started having this issue yesterday, have tried different charger and usbc cable combinations, cant even get my pc to recognise it as a plugged in turned off xzp and it wont turn on only show the battery icon with low level indicator in the red.
I have a similar issue.
When I connect my XZP to the pc using a Rampower cable USB-C to USB (sold as 5Gbps and 5V/3A power, thus an USB3.0 with fast charge of 15W) I suffer of the same issue exposed above: randomly the connection get interrupted.
While, charging the phone, yet with the above-mentioned cable and original Sony charger, I get no problem at all!
NB: I have never tried with the original USB cable...
Common fault with the xzp.
The actual connector from the logic board that the usb c module connects to burns out. Require a new logic board or connector to be replaced/soldered on and new usb c module.

This is good news, because sourcing a mainboard is half the price of the phone, and I've already spent money on a new battery and charging port etc.
My 2nd G8142 phone has just started displaying the same symptoms, and I can't afford a complete replacement.
Can you confirm that this is the part I need? https://www.aliexpress.com/item/4000160901916.html
If so, I'll grab 2, and install into my old phone first to confirm the fix, before then installing one in my newer phone.

Lucky you!
I'm onto my 2nd one, and have had the same charging issues with both.
Both phones have been rooted with a custom ROM, and I use my Dell smart-powerbank to charge them fairly often. So perhaps that is the cause of the early failures on both.

Unfortunately I can't confirm if that is the exact part you need as I don't do repairs. All I can confirm is that my repairer has stated that he has seen XZP's with the same recurring issue with the connector burning out.
My guess is, that is the part as he had to micro solder a new connector to the logicboard.

That's good enough for me! I'll grab a couple of them and see if it fixed my older phone first (because I've already tried the battery and the USB-C socket etc) Will update once I've done the repair.
Hope you can fix that problem and share some experience on this issue. Mine has a similar problem. The difference is that it can be charged to 100% but very slow and randomly stop.

Yep, that's how my issue started too. It'll progressively get worse.
I've just bought a Google Pixel 3 XL as my 2nd XZP has ceased accepting any charge at all. I'll see if these motherboard sockets fix the issues, then keep one and sell one. Otherwise I'll just sell them both off as parts.

I talked to some tech on Alibaba (A Chinese shopping website) and they said it can be fixed by replacing that socket. But the replacement requires professional welding equipment and skills. Or the motherboard can be damaged. That's why I am looking for other people's experience before I take step myself. If you succeed, please update this thread. I think there are more people like me who is looking for successful experience from others. Thank you for your sharing.:good:

I'd recommend getting magnetic USB-C cables for that matter. I've bought one (actually three but only one with the magnet) from AliExpress with PD-capability (they cost around 10€ for cable and magnet combo, 7€ for the cable and 4€ for the magnet itself) and I'm totally satisfied with them. I only have to unplug them if I e.g. use my wired headphones for telephony (since my bluetooth headphones have got a bad mic) and flashing updates/rooting via Odin (because they only support USB 2.0 speed standards).
