Got phone from Bell on a 2 year contract about 8 months ago. When it arrived I put a glass protector on the screen and the Unicorn Beetle (the tougher one) on right away. I've been very careful with it since.
It's worked fine until I joined the Android N (via the Beta) where I found the battery drop quicker than normal.
While the phone was at around 30% charge, it suddenly turned off and would not turn back on.
I tried following these steps to fix it. No luck.
QUESTION: I called Huion to get it serviced since it's still under the one year warranty. They said that if the phone was rooted to not bother sending it in because they would know. Based on all my research, I have no idea how they would know. Would they really?
SYMPTOMS:
Phone does not show anything on the screen.
I bought a new charger and cable and have been doing different tests and have been getting no luck.
When I plug my phone into my computer I get this error:
"USB device not recognized. The last USB device you connected to this computer malfunctioned and Windows does not recognize it. Recommendation: Try reconnecting the device. If Windows still does not recognize it, your device may not be working properly."

Once its plugged into my computer and i hold down the power button i hear my computer make a sound to indicate that a device was unplugged and replugged back in. But Nexus Root Toolkit or Vysor does not recognize the phone at all.
Nexus Root Toolkit does not detect my phone.
If your image when you turn it in is still unlocked and rooted or even locked and rooted they will know.
Are you able to get the phone to turn on?

See if you can get the phone to bootloader mode. You can try the Nexus root toolkit to go back to 7.0 stock.

Nothing I do turns the phone on.
I tried every step on this site, all with no effect (phone stays black)

You need to charge it..
Powering off at the 30% mark is a known bug to some running 7.1.1.
It happened to me all I had to do was hook up the charger and let it charge then it will power back on.
This only happened to me once and some others as well

I had it plugged into three different chargers (including the official one), with three different cords, each for over three hours (often over night)
No luck.
You may have damaged the USB-C port. The only time I've seen that Windows error was when I damaged the USB-C port on my laptop with a slightly crimped USB-C connector that I didn't realized was damaged. After damaging the port, I changed cables to one that was not crimped, and I saw that error because of the damaged port. So I'm thinking it's possible you may have damaged the port on your phone, and it's not charging. Hard to say. Just trying to help. Look closely at the port with a bright light and see if you notice any damage.

You tell me? http://imgur.com/a/NlOxv
I have tried three different cords and chargers btw.
I can't tell from those photos.....probably no way to get a good enough shot. I was able to compare my damaged USB-C with an undamaged one, that was really the only way I could tell. I could see there was some slight but noticeable damage to some of the very thin wires surrounding the wafer in the middle of the port (best I can explain). Need a bright light to see well enough.

Hi everyone!! i'm desperate since i think i came with an expensive, unusable phone in my hands.
I read and searched thorough but there doesn't seem to be much clue on this, just one or two lost threads....
Someone care to drop a hint to help me ? ive lost all hopes.....
My x10a, after using it for , say, 1 month, rooted with latest xx23 firm (and used for a week or more , perfectly fine) ... some days ago, it stopped recognising USB port.
IT does not charge, with no existent charger or usb cord; it does not recognise usb connection of any kind, to any computer possible.
It lasted till last battery charge died, and no way to resucitate.
Afterwards, i came up with something: i bought a crappy, chinese battery-charger, drop my X10 battery overnight, and the phone then booted and worked fine.
So it is the USB connector/port/circuit. I even though of reflashing or re-rooting, but you can figure out that i can't do that anymore (no usb :S).
I can't give it back to SE or seller since it was brought overseas, and it even has some little marks on the corners (they'll just claim i dropped and so).
Any caritative soul please?
I opened following McKebapp guides, but didnt find nothing in particular.
Do you think i should risk in getting hands dirty and, say, re-solder an usb jack?
If not, i offer in sell all spare parts, almost new, or even sell it at a very good price, e.g. for bootloader experimenting....
Thanks !
Are you sure there is no gunk in the port or the cable's contact itself? Or even a bad cable?
Try this.
(1) Buy yourself a can of contact/electronics cleaner spray.
(2) Remove battery from phone to ensure you have no power going through there.
(3) Spray area clean and wait for it to dry.
Afterwards put battery back in, power up and plug in. See if that works
Yes, i tried all these... but nothing... Of course, i tried using up to 10 different usb cables, even bought new ones... but the strange thing is that nothing really happened, in order to mess or 'break' something on the phone...it was from one day to another... strange....
I wonder if the port is soldered to place on the board or is just spring contact based. I believe Bin4ry had his phone disassembled - you can ask him. If it is spring loaded contacts - there might be dirt underneath that needs to be cleaned up. If it is soldered - a joint might have broken and need resoldering.

OMG... NEVER do that to a PCB with BGAs...
You'll shorten the connectors underneath the BGA soldered chips by fluid that stays there thanks to capillary action.
@rodrigofd:
Here you can see the USB connector itself, on the very left side:

IF there is any mechanical failure, one or more of the five solder points in the middle of the connector is loosened.
But I can't believe it's a mechanical / solder problem.
Wiggle the USB charger cable a little, while having it plugged.
That way, you'll determine if there is any hairline crack.
If there is any, you can think of resolder it..
If you ask me, I'd say, some SMD fuse has blown up or there is an hairline crack between the PCB layers.
To determine that, you'll need a 3rd level schematics and some electric circuit reading knowledge.
If nothing helps:
Wait till there is a OTA Update that unroots the phone.
Then bring it to service..
The same thing happened to mine. While it was charging on my desk, and I was asleep.
I woke to find the phone on the floor but the USB cable was attached.
Using JuicePlotter (which had been running) it seemed that the phone had stopped charging around the time I had missed a call.
My detective skills allowed me to deduce that the phone was fine, but then when it rang - and started to vibrate - it rumbled its way off my desk. I believe it was not hitting the floor that damaged it - it's carpeted and not much of a drop - but the shock to the USB cable port as it swung itself off mydesk, effectively "hanging" itself.
I'm afraid I had no luck fixing it but it was only a week old so O2 replaced it immediately.
These days I ensure the phone is FIRMLY wedged somewhere when charging it.
Does anyone else's charger keep dying/burning out/burning up? I've had my TF since July and after 5 weeks it decided it didn't want to charge anymore, so I sent it to the Asus repair center in Houston, Texas and it came back three weeks later and everything was fine.
I just got my dock two days ago and pretty much had the tablet connected to the dock and the charger connected to the dock for almost all the time I was using it since it was taking forever to charge both batteries. By the end of the first night the tablet was completely charged and the dock went from about 4% to 80% during the whole time I had it charged (but I was using it at 1.4GHz with the screen brightness all the way up). While it was charging the power brick (the actual transformer lol) was getting really hot, almost too hot to touch, but I know those normally get hot when they charge stuff so I didn't think anything of it.
I tried to finish charging it yesterday and noticed that it stopped charging (again). I checked my AC power cables and everything was connected, I re-seated the usb end into the adapter, rebooted the tablet and tried connecting the charger to both the tablet and the dock. Neither would charge. I also tried the adapter in different outlets too. I'm not going to send it back to Asus this time since AFAIK there's nothing wrong with the tablet or the dock itself, I'm just going to shell out $40 and get one off of ebay. If that doesn't fix the issue then I'll send it back because I don't want to be without it again for three weeks.
Has anyone else had this happen to them more than once?
Funny you post this. Mine stopped charging last night. I know the cable is good because I can hook it to my computer and transfer data. However plugged into the actual power transformer, it will not charge. Tried many different outlets and did my best to make sure it was not damaged.
I think we need to find a good way to charge it from USB 3.0 ports on the PC by buying a PCI card or whatever, and keep the power brick for traveling
They seem very feeble
I still have my first one but it stinks of burned electricals
It's bull**** that they don't sell the chargers separately and there aren't any third-party chargers available. I think I'm going to try the charge from PC mod for my normal charging duties since my PC is always on and my PSU is 850w.
Why can't we just directly charge from a USB 3.0 port (or two of them for that matter with a y-cable like they do for portable HDDs)? I may have to rig something up with the help of my father who's an electrician

The USB 3.0 port on a pc will not charge unless you want to leave it overnight turned off. The power connector/connector on the TF is a physical USB 3.0 connector, BUT not an electrical 3.0 connector.
If it's not an electrical connector (odd thing to call it since these run off electricity no matter how you spin it, but I know what you mean ) then how does it get charged using the power brick? Are there leads in the cable that are specifically for power and not for transmitting data (meaning they don't connect to anything in a USB3 port on your PC)?
I was able to fix mine by throwing my power brick into the freezer for about a half hour or so. I followed this thread.
http://forum.xda-developers.com/showthread.php?t=1284303
I was about 1 click away from buying a universal Dynex one that is on amazon and then read around, so far so good. Hope it works for you.
I just made my own PC charger and so far so good, I didn't even have to buy anything!

Both usb 2.0 and 3.0 have one 5v power and gnd line with limited current capability. 2.0 has one pair of data lines. 3.0 has two pair of data lines. The TF power cord is essentially a 3.0 cable with coductor # 7 ( part of a data pair in 3.0) used to sense a gnd signal from the tablet to tell the power brick to output 15V on the normal 5v line. If the brick does not see the gnd on pin7, the 5v line only outputs 5v. This is why a 2.0 usb extension will not work.There is no conductor 7. Best bet buy the dynex video camera adapter and set itt for 15v to the usb connector.
Hi,
I don't know if I'm posting in the right section, but here is the thing. I've got GeeksPhone Keon Developer Preview, It's a Firefox OS phone, but I've flashed an Android version on it. Everything worked great for about 6 months, and then the phone stopped charging, and it was also not detected by PC. When I plug it to a PC the phone does not detect it's plugged in also the PC does not detect the phone. I tried other microUSB cables and it's the same. I also tried flashing the Android again as I thought maybe it's software related but the problem still exists. Hopefully I installed recovery on it. I currently charge the battery externally, everything else works as expected.
Yesterday I decided to mess with the phone, as I don't have the warranty. I opened it up and checked if the phone actually has power when plugged to the charger. I noticed that the battery is powered so It is charging but the Android OS does not detect that, and decreases the battery via software. I think that the D+ or D- pins are broken, and I'm not sure if they are used for the phone to know if it's charging.
Here is the picture of the circuit board and my findings. Camera is not great so the picture is not that great also.

0. Is the microUSB port, and I guess there is a problem with it, maybe D+ or D- pins got broken.
1. Those are D+ and D- resistors they are good I've tested them.
2. Those are battery pins. When I probed them when micro USB is plugged in they have power.
3. It's some kind of a IC for power, I think it's used to switch power to the battery from microUSB.
I don't have that good soldering skills so I couldn't resolder the microUSB port, so I'm asking if someone knows another approach to enable the charging via software, as software does not detect that battery is charging, when actually power from microUSB comes to the battery, and because of that it decreases the battery status on Android.
So I'm thinking if I can execute some command so I can trick the phone to believe it's charging, so the battery will charge and when I plug it out I execute the second command to turn off fake charging?
Thanks in advance!
Funny that you have this problem, I just fixed mine today that had the same problem. Basically the micro usb port stopped working because the parts soldered on the motherboard were loose after too much wiggling (cheap mtk phone I guess). I tried resoldering but its just too small, I could not event test the connexions with a multimeter. So I went to one of the million of asian cell phone shops in indonesia where I'm actually travelling and paid 5$ for a guy to fix it. They do it all the time and have expert fingers. Not my phone plugs perfectly, try to find one near your place, wherever that is

What happens if you put a charge over those connections? It won't accept any? Or does it charge but the software isn't detecting it? Another way of fixing it would be making a separate charger for your battery only, of course that would mean that your phone is useless while charging. I'm pretty sure if you force a charge over it it will absorb it, but I wouldn't exactly know how you could check the battery status so that you don't overcharge it this way.
I Have a problem with my phone which is turning me crazy.
The battery wont charge while turned on, while turned off it is constantly starting up to show the battery load picture, then i shuts down again and the battery charging picture pops up again. This happens all the time. I cant do anything about it. It does not matter if i plug it into a wall or into my pc. Also its not the cable or the adapter. I really dont know what to do. So far, ive come to the conclusion, It does recognize that its charging whilest being off, so its not some thing that has to do with a hardware issue. It must be software. The only thing I have used is an app called rootbooster. It changes some settings in the root of the phone for longer battery and ever since i have this issue.
In Recovery it does not charge as well.
I have already flashed my rom again and reset the phone.
Anyone knows anything about this?

Probably not software. Sounds like your micro USB port on your phone. Give it a good blow, might be lint or dirt stuck in your port. Especially if you've returned it to stock and its doing this while powered off. That or your charging port has developed a fault.
It is 99% likely to be the usb socket......
I've had 5 Galaxy devices, all of them use the same type of port, and 3 out of the 5 have failed.....
IMO, the USB port design is pathetically fragile for the job Samsung intends it to do.......
http://i.imgur.com/rVnFwJM.jpg
If It would be the usb socket, wouldnt the phone not even recognize the usb plug? Because now, it does now when I plug in an usb cable. After a few blwos it still does not work.
The usb socket has a number of connectors/pins that are used in various combinations for specific tasks.....
Charging, connecting to a pc, otg etc......
It *could* be that the pins responsible for charging are the only pins affected.....it doesn't even need to be both pins....just one broken pin would be enough to affect charging, but would leave the other functionality intact....
I wouldn't advise poking into the socket with anything in an attempt to repair it, that'll probably just make things worse.

USB has red wire (Positive - VCC - Power - PIN 1 ) and black wire (negative - GND - Ground - PIN 4 ).
Along with it has White Wire (Data+, Communication with PC - sending signals to PC - PIN 2 ) and green wire (Data-, Communication With PC - return to smartphone - PIN 3 ).
So it is possible that the "red wire" in this case PIN 1 and PIN 4 of USB, that developed a fault.
Meaning that you have only PIN 2 and 3 not being fault.
If it has Warranty and with Stock Rom, take it to the samsung authorized repair and they will change the usb port.
^^agreed.....
Replacing the USB 'daughterboard' involves removing the screen from the frame......very tricky to do with the potential to cause further, more expensive damage.
If, during rooting and flashing, you have tripped knox, Samsung may well argue that you have invalidated any warranty you may have had....so be aware that the offer of a warranty repair *may* be denied to you......that is, if knox *is* tripped and they check for it....

But isnt it weird that whilst off, the phone does know when it is connected to USB?
And another question, My computer does not connect with the phone at all. No charging and not reading its USB. Isnt there a possibillty that because of some root mistakes the phone wont charge anymore? Is there a possibillity that this is software related? Because I did not bump my phone to anything. I have just ran that app and ever since its not charging anymore or connecting to my PC.

Well have you tried a factory reset?
It could be the soldering part which connects the port to the board maybe broken. Maybe it just slightly touch to your board, that's why it just pop up and show charging then it went away.
Unfortunately it is not a part you can hand re-solder with any degree of success.....The contacts are *way* too small.....
http://i.imgur.com/rVnFwJM.jpg
Solder tools has many sizes. You need expert to do it. Otherwise if you short each other,you will be in more trouble.
Mate...seriously? I've seen these usb ports off the boards....The connectors are tiny.....You'd need a needle point on a low powered soldering iron. You'd also need a lighted magnifying glass just to be able to see what you're doing.......
Oh, *and* a rock steady hand.....which is something that most humans don't have.
There is a reason why these microcircuitry boards are assembled by robots....it's because we would bork too many of them if we tried it......

Yep, agreed ^^
The gf's Nintendo DS charging port broke, worked for a while by twisting the charger lead around until it made a connection, then stopped even doing that, so I thought I could just permanently solder the charger wires to the connectors in the port for her, so it would work at least while plugged in
Soon as I took the thing to bits I could see straight away there was no hope, even with a powerful magnifying glass and the smallest soldering bit I could think of, there was no chance at all, I would have soldered 2-3 pins together at once if I'd tried
Micro-Electronics need machines to solder them, not humans
Try official repairing centre, there might be chance for you.
Can anyone help me, I got Reverse charging when I plugin with stock charger.
The phone still said "Charging" but the battery not coming up.
I have to reboot to recovery or fastboot to charge everytime.
I tried to reset factory or anything I could but nothing help.

This happed to me as well. At first I thought of replacing the phone but then I realised one day I went out when it rained and there was some chance of water entering into the charging port so I used a hair dryer and put the phone deep inside a bag of rice for 2 days only at night and then the problem got solved. This may sound stupid but given it a try. Even the often pop up of reverse charging stopped from then. Hope it helps
Reverse charging notification appear when u plug otg cable. Between otg and normal usb cable has different pins connection to be worked with. It could be on phone female socket had some water inside, or conductor dusk, that make it became short circuit with otg pin, try clean it. If that didn't solve the problem, check if the pin inside got damaged or not, in some cases when i repairing phone, the water getting inside between the socket and the board, so u need to open the back cover to check it. Sometimes with just blowing it with hair dryer can clean the water, but there is another problem if its like salt water, the water can be dried out but the salt wont be dissapear and become a solid semi conductor type that make short circuit happens.

I have the same problem, maybe is dust or some liquid, on usb port, you can use some product cleans contacts for electronics, if not resolve, you need to replace the usb board, you can do it by yourself or leave it to a professional, be happy xD
