What actually happened was that a few days ago I had a bit of a "mishap" (bit of an accidental hard pull of the phone off the desk) with the USB cable which caused the slot to become extremely loose, so much so that the cable would just fall out. I decided to send it back during the school holidays which will come in a weeks time as it still worked but was just very loose.
I did some research and found that Blackberry USB cables were the tightest, so I ordered one and it came today. This one fits very tightly even with this broken USB port. Its really a challenge to get it in and out.
So I'm now wondering whether to send it back or not? Is it worth the hassle?
I think maybe I should anyway, since I have a year of contract left with Vodafone. The day that the accident happened I used a pin to straighten that middle bit that's inside the port as that went too high up with the pull. I moved it down slightly.
Might that little bit break off in the future?
What do you think? Should I send it back for repair?
Honestly if you don't mind the time and effort it takes to get a replacement, I would just do it.
Maybe find out their policies on multiple replacements just incase something real bad happens in the near future
Thanks. I think I will send it back next week then. Better safe than sorry lol
I would send it to repair. But be aware that since this is a damage issue it is not covered by your warranty.
Hi all,
well I'm not happy at all. I am on the 3rd Nexus so far, the first one started having the phantom charging issue within about 2 weeks of owning it. That went back for repair, but when it came back I walked out the store and it would not turn on! Went back and the swapped it for a 'new' one. I say new but I'm not sure as I didn't see the box being opened. I started having problems with that one within a month or two, same again. Also every now and again it would not switch on easily without plugging it into a PC or something.
Anyway, I recently woke up one morning and the battery had died over night, tried to charge it with no luck. I have tried everything, the USB trick, leaving it overnight, all sorts. When I plug it into a USB port I get the ding dong noise, but about 4-5 seconds later it disconnects, then re-connects... and cycles again and again.
Well took it back to the shop and sent for repair and it came back exactly the same, because they say they found water damage!!! This is total rubbish and the photo 'evidence' they provided did not convince me at all! I have since opened the phone up and the tiny bit of residue on the top left of the main PCB looks more like flux than a water mark to me. The moisture sticker is fine and the area in question has hardly any components there, just a cap and resistor. I am an electronic engineer by trade and I know it would take more than that to break it!
I am certainly not going to lie down and let Vodaphone crap on me for a phone that has been well looked after and is old about 8 months old, there is no way that I'm prepared to pay £45 a month for the next 8 months for nothing!
I have ordered a new USB PCB so I will try that when it arrives but I'm wondering if anyone has had similar issues and managed to resolve them? I haven't got another battery I can try but I would be surprised if it is that?
Hi all,
the wife's HOX died suddenly, won't turn on at all, wont recoginse being plugged in into either the wall or the PC, no lights, nothing.
Unfortunately she has taken a number of pictures of our 5 month year old son on it, which obviously we would like to have back!
I'm competent with taking the phone apart and putting it back togther, however what I want to know is how the Samsung Flash chip is connected to the mainboard.
I can see black glue around the outside of it, but I am unsure if the underlying pins are also soldered down.
My intention was to razor blade the glue away and then buy a knackered (but working) HOX and transfer the chips over.
Obviously I wouldnt be able to do this if the chip is soldered down. I have monkey hands when it comes to soldering things.
Is anyone able to offer any insight?
I've had a google and read the datasheet for the specific chip, but it says nothing about how it is connected.
Thanks in advance.

I really can't see this being successful, sorry. I'm fairly sure the chip is soldered down, and the chances of damaging the chip are very, very high if you want to try and get it off.
If the phone didn't come into contact with water a JTAG recovery might be possible. It may not get the phone working again but it could get your data back. Alternatively companies like DriveSavers have an excellent reputation for getting data off flash chips, but it'll cost you in the region of $400 - $1400 (I got a quote a month or so back, when I thought my HOX was finished.)
I really wouldn't recommend trying to remove the chip though. You could do irreparable damage to the chip, which would render it completely unreadable.

Try first change the battery to see if the phone will start again it is the cheap way and most secure
de4life - thanks, I've had a quote for data recovery from Kroll. They want £95+ to look at it and provide a list of what can be recovered and then between £195 and £395 for actually recovering it for me. Far too expensive!
As for JTAG, there's been no water damage whatsoever; I've had a quick Google and it says this is more for Routers. How could I do it to my phone? Im not fussed about getting the phone working again, just want the contents of the flash storage back.
Thant - alas, the was the first thing I tried. New battery has made no difference. Which is annoying as her old Desire Z showed the same symptoms, we bought a new battery and its works again. She's currently using that until we decide what to do.

First thing's first, if you do go down the data recovery route try to avoid companies that charge any type of analysis fee. Kroll are a well known company but I've not heard much good things about them. I went through an extensive search of companies when I thought I'd killed my HOX and found DriveSavers were the best in terms of reputation, and they don't charge a fee to look at the phone. They are very expensive though, perhaps more so than Kroll, and you have to send the phone to the States which is daunting and costly in of itself (I assume from your £ quotation that you're UK based?).
It's good that there's no water damage. It's difficult to say what can cause the motherboard to suddenly stop working like that, but it's unlikely there has been a serious short circuit that could have affected the memory chip. Have you tried dissembling the phone completely and putting it back together? It may sound ridiculous to even try it, but when one of my older phones suddenly died I managed to get it working by taking it apart and then just putting it back together again. There are a lot of connections within the HOX motherboard framework that could easily have come loose. You might already have done this, but just a thought.
In terms of JTAG, it can be done on mobile phone motherboards with the right equipment. It's usually used for soft bricked phones to reset the software back to its original form if it's been corrupted, but I have seen cases where hard bricked phones were brought back to life using this method, including the HOX. It's not really something you can do at home (not cheaply, anyway) but there are companies that provide this service. One of the more popular services is here: http://mobiletechvideos.mybigcommerce.com/htc-one-x-jtag-brick-repair/ - I believe they post on here from time to time as well. Again, based in the States, but significantly cheaper than data recovery and as far as I've heard very professional. I don't know of any mobile phone JTAG services in the UK, though they probably do exist.
Keep in mind the data chip on your phone is likely fine. Even if the motherboard has stopped working, the memory chip itself is unlikely to be affected and will still contain all of your data - albeit in a scrambled form. If you send it out to companies then they can potentially damage the chip beyond repair, if you go down the route of sending the phone out to repair/data recovery companies I would urge extreme caution. If it's still on the chip the data itself isn't going anywhere. Take your time and make sure you're sending your phone to the right people, because one false move and your data is gone for good.
Basically what happened, was on Friday, my phone got stuck in a boot loop. It would get to the "Optimizing Apps" screen and shut off again. Other people may just get to the Verizon screen, or even just the LG screen. I looked it up and found that it was a major issue affecting many people, so I just filed for a warranty and received my new phone today. Well, on Saturday night LinusTechTips, a popular tech YouTube channel(You should really check them out, they are great), released a video on how they fixed a dead Graphics Card and PCI-E SSD by heating them up past the melting point of solder and then testing them. For them, it only worked on the GPU. As I was packing up my seemingly dead phone to ship back to LG TODAY, i decided to give it one more shot. I disassembled the device to the point where I could take out the logic board. I took the logic board and wrapped it in one layer of parchment paper and two layers of tinfoil, shiny side facing in(FYI tinfoil has two sides, shiny and matte). I then placed this package into a barbecue. I turned on the left and middle burners and left the package with my logic board inside on the right side to the grill so it wasn't receiving direct heat. After 10 minutes, I took it out, re-assembled my phone and it booted. I was able to get all of my pictures off of it. This has only been confirmed to work on my phone, but seeing as this SAME issue is affecting thousands of people, It's definitely worth a shot. If you are going to use an oven, PLEASE, make sure it's above 385 degrees Fahrenheit and that you don't plan on using that oven for food ever again, this may release some toxic chemicals etc. I plan on using my grill again, so I just made sure to leave the grill open for 24 hours and I'm going to clean it before I use it next. If you have any questions let me know!
P.S. My LG G4 was the Verizon model.
I highly recommend doing this ONLY if you have no other option. Remember that heating a logic board to high temperatures can release toxic fumes. Don't use an oven you use for food preparation! Toxic fumes can leave residue in the oven and will be re-released upon reheating over many cycles!
Assuming LG's press release regarding the issue is correct and it is really a loose contact, this "fix" could actually work. Of course, only if the loose connection is a soldered connection. Though, it's controversial. You have to remember that the melting point for SMD solder is around ~350°C, or 662°F. So 358°F, or 181°C, is not nearly enough to actually re-solder a loose connection. My guess is that the loose solder point is only expanding due to the heat. There is no real reconnect. It might only be a matter of time until it also breaks. If you could locate the actual loose connection you could really re-solder it and have it fixed permanently.
I've done this on many many devices, including graphics cards, smartphone logic boards, PC mainboards etc. It only works if a soldered connection has a crack small enough that heat expansion is enough to gain reconnection. If there is a loose contact on the PCB or the "crack" in the solder is too big, it does not work. Also, if you really have a dead chip, this trick also won't (always) work.
I read a similar story on reddit. The guy put his main board in the oven, reassembled it, and the phone started working. The last update I read was 3 days later, still working.
I fixed mine temporarily by heating up the emmc chip using solder hot air gun. It seems to be just the emmc chips connection.
Failed again after a fortnight when the phone got too hot. The connection seems to break when the g4 gets hot.
One option to try is to boot the phone inside a freezer. I found that worked too.
Pretty poor quality control on lg's part.
I'm going to try again and see if I can fix permanently.
Worked for me too
I have a LG G4 H815 with serial number starting with 507. It died yesterday night. The bootloop escalated quickly to full death. Even the freezer trick did not work.
I followed the OP instructions. I heated up the grill to ~250 degrees Celsius and cooked the motherboard for 10 minutes.
Magically the phone has been working for a couple of hours since and I have been able to backup files to the external SC card.
I wonder how much more will it work.
Thank you for help OP!!!
Word of advice to other LG G4 users. Backup your phone regularly. Use an external SD card. Set the camera to save images and videos to the SD card. At least at doom day you will have them saved.
Cheers

any more info on this? Looks like my phone bit it the other day, no boot...just dead...
I'm going to take her apart to see if I can find a bad solder, luckily I still had my G2 lying around.
NFN, I sent mine back to LG US in Texas for a full warranty repair. 10 days RT, no cost at all, shipping included.
No unfortunately. I managed to overcook it and it stopped booting altogether
Do you have the address and info Re your communication w/ lg

What is the beginning of your phone's serial number?
Hi bro kindly tell is it worth to install custom rom kernal with root to prevent the cpu to clock high speed so it will not go into bootloop? My is also 2 years old thanks
250 degrees F for 6 minutes and brought the phone back to life. We'll see how long it lasts.
Actually it worked on BOTH G4s I have. I first just went dead and I bought a used one for $100 on eBay and it worked fine until the bootloop showed up.
I have a factory unlocked SM-N975U1 Note 10+, using on AT&T's network. It recently had an update pushed to it (early April 2022) that I let install before I went to sleep, then the next day found that wireless charging no longer works. I suspect the update is the culprit - so a software glitch. I have tried everything listed here: https://tinyurl.com/yckk9mmr by The Droid Guy, from rebooting to refreshing the system cache, to no avail. The wireless charger in my truck, on my desk at home, and my husband's wireless charger - all of with which it worked perfectly before the update to charge the phone - all recognize the phone is there but the LED on each begins to flash rapidly, so I am certain it is something with the phone. I am about to try to root the phone so I can install Titanium Backup or try Nandroid then do a factory reset. Short of that option of last resort, do any of you have any idea what else could possibly be the issue here? The only other thing I can think of would be the fact that the back glass is cracked, but has been for a while now, so while I could see correlation, I do not see causation. But I am by no means anywhere close to being an expert, so I may be wrong on that point. Any advice or suggestions would be greatly appreciated! I do not want to incur the expense of a repair from Samsung, and am considering perhaps just getting a Qi receiver - the type you'd add to a phone between the phone and case to add wireless charging to any phone. If nothing else, if you have any recommendations on that point as well they would be most welcome.
Thank you in advance for your time and assistance.
Could be a battery failure. Get the rear cover replaced and the phone inspected for damage.
Replaced battery if it capacity is less than 80% of when new ie SOT.
Updates can break things and make troubleshooting more difficult. This could've been caused by the update or be purely coincidental.

What happens when you charge with the usb c cable? Any warning message?
Is Samsung replacing these phones for this issue? I am so irritated. Just press the back of the phone hard and it will work again??? I remember the Fonz hitting the jukebox on Happy Days, but seriously on a $1,000 phone? Gimme a break.
I just had the same problem. Is this really a thing? I can't believe this is a known issue. I followed pressing just below the camera to the right of the back and now it works.
(see the post I found below).
There seems to be a problem with the wireless assembly’s contact to the
mother board which has a temp sensor attached. Give your phone a gentle
press on the back just under the camera and a little bit to the right.
This is just a temporary fix as the wireless charger will probably lose
contact again. Hope this helps.

My Galaxy Note10+ quit wirelessly charging yesterday. I tried this and it worked! Thanks!
If I recall correctly the coil for wireless charging on the N10+ is connected by a ribbon cable. It may have become detached. Unlike the contact points Samsung used for the GPS antenna like on the S4 they should not fail.
Always use a good case to protect the N10+ from high G loading during drops as they can damaged the mobo or knock connectors loose even if there's no apparent outside damage. These are relatively heavy phones that wuv to corner impact when dropped.
Thank you for responding!
Weird, I have never dropped it. Its brand new and I have a good case on it at all times. Maybe it was just loose to begin with? Will this fix it for good as long as it doesn't get jarred loose?
So you are saying the contact points like the S4 would fail and this ribbon cable should not fail, just can come loose?
What does "wuv to corner impact" mean?

The S4 had point contacts that were held in place by pressure and could corrode over time, completely different from a ribbon connector.
Whatever is loose or broken will likely need to be serviced eventually.
I wouldn't sweat, I never used wireless charging on my N10+'s, don't even know if it works. Cable charging is superior, faster and the C port socket on the N10+ is robust. Good for many thousands of cycles.

Would pressing harder on the recommended spot possibly get it to mount down firmly to where it wont have constant problems? Or will it just get worse?

Have the rear cover pulled and see what you got.
The coil assembly may have failed.
If the battery is near 80% of its original capacity then replace that then too. This phone is too valuable to be mucking with it by pressing on the rear cover... not a good plan.
So guess what? I had recently purchased this unit as NEW, Sealed with 1 year factory warranty with on eBay. Seller had good feedback so I thought I could trust them. I was so perturbed with this charging issue after only have it for two weeks that I got with Samsung Support. I figured I was covered since it was new, sealed and had a 1 year warranty with Samsung. They verified that this phone was activated April of 2020 and the warranty expired April 2021. He also said he can see that the battery life has been used to where it only has about 50% of the potency it had when it was new. Total fraud!!!

Contact your bank and see if you can return it and have the bank do a charge back. Your state attorney general's office may be able to help as well but I would go with the first option and a full cash refund.
I do know a reliable vendor for new ones if you need that contact. I've used them. A1.
Thank you, I sure do appreciate that. Yes, I would love your contact if you would be so kind.
