[Q] N7100 Suddenly Won't Charge - Ideas?

Hi all, I'm pretty lost here. My Note II (N7100) suddenly won't charge. Earlier today it charged just fine. I've only ever run stock with root on it. It's not the charger, it's not the cable. I've tried many of both, all of which worked before, none of which work now. I flashed back to stock recovery and did a factory reset, and the problem persists.
When I plug it into a charger while off, briefly a gray battery screen with what looks like a stationary 'wait spinner' will pop up and then the screen will turn back off again. I know the USB port is not totally FUBARed, because I can flash it with heimdall in Linux. It shows up in lsusb when in the bootloader, but not otherwise. The port is pretty much spotless, especially compared with that on my GNex, which still works fine.
I've tried leaving the battery out for an hour, holding the power button, etc. It almost seems like a problem that could be solved by discharging some capacitors, but battery pulls always solved those on my Galaxy Nexus.
Any thoughts on other things I can try?
I can't even figure out how to contact Samsung support in case this is somehow a warranty/hardware issue. At least on their US site the N7100 isn't even an option in the pulldowns they want me to go through.

After some calls to Samsung USA and Canada, I gave up. Apparently the phone is from the UAE, for which Samsung USA has no phone number, and their repair centers won't touch it if it's international. This is really stupid and I plan to write to Samsung about it. It had only been three weeks since I ordered it, so I am returning it to the Amazon seller for a refund. I'll let them deal with their supplier in UAE I guess. I hate to do that, but it seems to be a hardware problem and I have no other recourse at this point.

I cant really help here but i wanted to let you know i had the same problem with a white note 2 from Carphone Warehouse in the UK, just stopped charging after owning the phone for 2 days (i had also only rooted and running stock rom).
Carphone warehouse replaced the handset for me and havent had a problem with the new one so far but its made me take extra care when plugging or unplugging the usb cable ( i use Airdroid for file transfers now). I guess there must be a defect with a limited few usb ports on the note 2.
I thought it might be a 3rd party usb cable to blame (i use a blackberry usb cable at work but ive stopped that now and only use the official Samsung cable).
Sorry i cant help just wanted to share my experiences, hope you get it sorted, good luck!

Thanks for chiming in Steve, good to know I'm not the only one. I saw another post on here like that too, maybe it was yours? There was no discussion. The strange thing is ODIN worked just fine. Maybe a loose connection only on one/both of the power pins?

Nah it wasn't me mate, I had just put it down to me being heavy handed and thought nothing more of it till I saw your post.
I've seen a post in the Jellybam thread today about the charging being down to software but I don't know how true this is as i've yet to check the facts.
Did you manage to get it replaced? I remember it was the worst feeling in the world when the realization hit that my phone wouldn't charge.

Yeah I just invoked the Amazon.com return policy, sent it back for a refund, and ordered another one. It was supposed to arrive today, but apparently UPS had some kind of mechanical issue and now it's delayed until tomorrow. I just need it to get here before my next month's Verizon plan bills so I can cancel before paying another month.

Sorry to drag up an old thread but this has just happened to me, EXACTLY the same as OP.
I've reset it, wiped everything, re-flashed latest stock firmware. Tried 3 different cables and two different chargers.
Pretty sure the battery is good because if I take it out of the phone and charge it on the dock, it works fine. If I then put the battery back into the phone, the phones works in every way except it wont charge
I have most of my digital life on this thing, I am so screwed without it. Look like its a warranty repair job then? Ive had the phone about 3 months from Phones 4U :crying:

Looks like hardware issue..

Happened to mine to T-mobile version. Never dropped it, never got it wet, only 1.5 months old.
WTF? Seriously?
Behavior:
Charges sometimes.
Charge sometimes stops at 70% or less.
Screen sensitivity screws up sometimes.
Data constantly being transmitted whether WiFi or cell network.
Never dropped.
Never wet.
Never harshly impacted.
Never rooted.
Tried factory reset.
Tried pulling battery.
Tried different chargers and cables.
Wondering if the trident aegis case put too much pressure on the charger cable by pushing it sideways with the flap.
Any ideas?

Hardware problem.

Check in the box, and if you have an EROS Group sticker on it that means it's covered under warranty here in Dubai, UAE as they are the main distributor here for Samsung products.
Sent from the rabbit hole.

This happened to me yesterday after spilling tea on it. I took the device apart as per this video, checked the connectors and reassembled it. Voila, the charger is working again. Obviously I take no responsibility etc etc.

My Samsung Galaxy Note 2 wont charge
I have also had this problem where my galaxy note 2 wont charge. I have tried all the chargers i have used successfully in the past and none of them will charge it now. I had the problem some weeks ago and now it has happened again. I only purchased the phone in January 2013. It is very frustrating. I have never dropped my phone or damaged it in any way what so ever. I have no idea what the problem could be but i will be taking it back to Telstra as i need it sorted out.

Same problem here - is this a generic problem with the Note 2??
I always put my phone on charge overnight , woke up yesterday and it hadn't charged. Swapped batteries - no problem - then put original battery back in, hey presto, charging!
But since then both batteries have run out and I couldn't get either to take any charge. Got it plugged in now and just like other people I've got a static charging ring showing, And no power.
Bought an external charger to try and get round this, but has anyone come up with a proper solution??

Strange...
a mate of mine just mentioned to me today that his note was charging strangely recently, apparantly he took an air gun (on low setting) to the charging port to blast out any miniscule dust n stuff and that fixed it!
Seems they're very sensitive and the smallest thing can make it act strange

Water damage Gnex- India

So nearly a week ago, i was travelling by bike. It started raining ridiculously, i had kept my phone in a plastic bag in the pocket of my windcheater. Somehow, the water entered my phone, i travelled nearly 20 kms without realising the water had already done the damage to my phone.
I reached home and saw what had happened, immediately took out my battery, cleaned my phone with a dry cloth and used hair dryer for about 30 mins. I knew the damage had already been done, coz the phone flashed a red led light indicating water damage.
I opened up the phone, saw the water marker stickers were in a perfect condition no change in color whatsoever, kept my phone in rice for about 12 hours and next morning i plugged in battery to see if it works, no result. PHONE WAS DEAD.
I took it to local repair shop, gave me an estimate, the phone worked for a min and then bam display was flashing on and off. Decided to take it to samsung svc, at first they denied repairing it since GNEX isnt available officially in India. So, gave them my phone and today got an estimate. Costs almost 200$ to replace the mobo! I was shocked! Anyway, my question is should i get my phone repaired? Can i get the parts from outside and get it repaired(not in samsung svc, it took them 4 days just to tell me estimate!)
Any idea which place in mumbai is good for repairing cell phones?
Thanks!

Try Indraprasth (Borivli), Alfa (Irla - Andheri) or maybe Heera Pana (Haji Ali - Mumbai Central). Good Luck

Did you use hot air? because that might be what have killed it. Plastic and hot hair don't always mix well, just like electronics and water.

Thanks for the reply guys. Tried indraprasth, first they said it will cost Rs.2500, now they are saying will cost more than Rs.5-6k and still no guarantee if it will work! So went ahead and gave it in samsung. Estimate is around 8k! I used hair dryer in normal/mode for about 30 mins and then in hot mode for 5 mins. When i tried to start the phone, the phone just flashed red led notification light and since then never turned on!
I dont know how much time it will take, even i know spending 8k on repairs is not a good idea, but this is my second phone in a year so had no option to buy nexus 4! Well will wait for the next nexus till then.

Hi! Im also facing a similar situation. Water entered in my phone on 9th June, I tried to turn on the phone but it wont start. I removed the battery and kept my phone in a bag of rice for almost 10 days. charged my battery using an external charger but the phone wont turn on
I would like to know what exactly the repair guy told u in indraprasth and which service center did u give ur phone. I don't want my nexus to die. I stay in borivali and any info from ur side will be really helpful.

The guy at indraprasth told me that water had entered the phone internals. Including earpiece,motherboard and display. My mobo worked fine for a sec or two and then the phone wud switch off again. After many tries the phone was dead. Then he said he can repair the phone(p.s smartphones cannot be repaired if mobo is damaged, only replaced) but there's no guarantee it will work. Then i went to samsung, they gave me an estimate of 8k +-1k. I will also get a warranty for a month, strange since this phone wasnt launched in India.
All the best, i would suggest go to authorised svc first and if you think the price is too high, then go to local.

Thanks for your reply. I went to Indraprasth and the guy said my phone is 'dead'. It cannot be repaired and it has to be replaced but he said it's better u don't do anything as its gonna cost u heaven and plus spares are not easily available. So now i have no option left but to go to an authorized service center. I would like to know what exactly the service center guy told you that's not working and needs a replacement and have u received your phone back from the center and is it working properly? I have sent u a direct message pls do check it and revert back when free. Thanks.

Water entered ear piece
Water entered the ear piece. In call quality is pathetic now. Any service center in chennai?

Strange Charging Issues *Please help!*

I'm at a loss as to what's going on. A few months ago I was changing up my ROMs and went to charge my phone and left the room. When I came back I was smelling that dreaded burning circuit board type of smell. Now none of my stock USB cords work with my stock charger. In fact I have 50 or so USB's and the only one that will still work is an old one from my Samsung device.
Just today I got a quick charge 2.0 and plugged it in and to my surprise it worked! Then about 30 minutes later noticed it was not charging. Hold the phone up to my nose and sure enough I smell a slight burning smell again. Is my device no longer going to be able to charge normally? I can't think of anything else to do. Could it be kernel related? Any help or troubleshooting ideas would be wonderful. Thank you so much guys!

Seems like that is a problem with your phone components not with software.Tell me about your battery life.If you connect your phone to a PC did your phone charge?Did you tried changing your rom with the original one?

Thanks for the reply. PC only would work if the cord being used was one of the 1 or 2 that actually work. I did have a little increased battery drain that seems to be decreasing my battery about 30% or so faster than before. I was going to investigate further, but it wasnt at an alarming rate as of yet. I honestly chalked that up to the ROM. I have Multiboot installed and CM6 is the same...100% hardware issue at this point...just not sure if the root of it started from the kernel or not.
I do have an update though...so it seems the part that burned last night was the final straw and now even the 1 charger that worked won't do anything...seems like I'm dead. Took it into Sprint (I have insurance) and they are going to replace it. Sadly looks like it won't be here until Tuesday. I tweeted Sprint about the issue and they'll be calling me shortly. If my insurance/warranty covers my issue and it's believed to be a defective phone I do not understand why I should be without a phone for 6 days. At the very least give me a loaner...but even that doesn't seem to be the best solution for an issue such as this. Good news is my phone won't take a charge so there's no need for me to try and make sure they can't tell I'm rooted.
Sprint used to be really good about customer service w/ having phones overnighted to your house or in store exchange. Those are distant memories now though.

Ig that helps you.My phone is in the repair store too and a guy from HTC told me that the repair for my phone will last for 40 working days ).So...6 days it's a WONDERFUL period.I am not so lucky as you.
P.S.They just have to change my camera module.

Mi 6 seemingly bricked after 3 mths, won't turn on/recovery boot, no water damage

I have a 3-month-old Xiaomi Mi 6 that was working perfectly until Friday. I took it off the charger at around 9am, and by midday it had switched itself off. Now it's basically bricked; no amount of charging or holding power/volume button combos can wake it up. It's not detected by my PC over USB and display/notification light stays off. I'm currently leaving it off the charger for a few days in the hope it's a hard software lockup that needs the battery to drain before it will reset and power on again, but I'm not hopeful. I haven't had any water-related incidents with the phone, about the wettest it's gotten is in my shorts pocket at the gym, but I don't sweat much so pretty confident it's not water damage. Anyone got any advice aside from sending it back to Xiaomi for repair?

I was reflashing my mi6 through the TWRP recovery and the process was stuck at 99%. I waited some amount of time and decided to "reboot" it. So I held down the power button and turned it off. Since then my phone doesn't react on the power button anymore. I have exactly the same symptoms like you described. In my case, it is my fault but I thought it should only update some files in the internal storage, nothing more. I'm puzzled how could it turn into the brick because of that. I expected that at least the screen would turn on.

Also, as far as I can tell, a charged phone can stay in the off state for months. I think you need to find a better way to drain its battery. You may try to connect an external HDD through OTG cable.

So, I was able to unbrick my phone. It was unlocked, so if yours is locked you probably need to disassemble it and put to the EDL mode with help of the tweezers. Try to connect your phone to the Windows PC. Windows 10 detects and installs Qualcomm HS-USB QDLoader 9008 driver automatically. After that, you need to download MIUI ROM Flashing Tool and a fastboot ROM for Mi6 from here h t t p : / / en.miui.com/a-234.html. Unpack ROM's archive to some directory, open the Flashing tool, click "Browse" button, navigate to that directory, then click "Update" and "Flash" buttons. It helped me.

Thank you very much for the extra information. In the end I decided to send it back to Xiaomi for repair, but I'll keep your tips in mind for next time in case it happens again. Honestly though, this is a pretty huge design flaw if the phone does need to be hard power-cycled every so often due to an OS crash. I've been very underwhelmed with MIUI too, so I may end up just selling the device once I get it back and switching to the most popular Lineage OS phone of the moment.

A riveting update for those on the edge of their seats, turns out this was a fault in the mainboard and they had to replace the part. Wowee, what a plot twist! Phone is back in working order now.

great to hear that you have your phone back, did it really took 1.5 months to get your phone back?

Regrettably so. It was a combination of factors: I live in Australia and bought the phone from a Hong Kong eBay seller (everything takes 3-4 weeks between asia/Australia unless you pay for express shipping), and they had to send it back to Xiaomi's repair centre there, and Xiaomi had it for a week or two, so it all took quite a while to get back. The joys of buying a phone on the grey market. This is the one area that Apple service shines.

I think defects are normal with these high tech smartphones. Quality control cant see the small issues that manifest themselves into mobile deaths over time.
You have just found other like minded people with the same problem here.
People without the issue are staying quiet haha.
Companies usually just build in these defects into their projections and swap out the device when needed.
I think most people who have warranty issues with Xioami are the ones like me who buy through third parties.
So you have to return the phone to seller. They then return it to their supplier who then passes it onto Xiaomi for warranty.
That's where the long wait times come from for international owners.
I had more issues with Sony and even with warranty directly with Sony my phone was returned bent from a warranty covered screen replacement.
They fix one problem and create another. At least with Xiaomi I'm seeing people get the phone repaired and that's the problem solved

Did you think about EDL Recovery ?
