[Q] GNex will not charge / USB Host not recognised

Hey all
Wonder if anyone can shed any light on what I think is a unique problem - in that I can't find anyone with the exact same issue.
Last weekend I took the SIM card from my GN to place in another phone I was trying out. The GN was powered back on and being used on WIFI as I was doing comparisons, shooting some video of the new phone with it etc.
Popped the GN in a drawer without thinking and left if powered on
(see if you can guess where this is going)
Messed around with the other phone for about 4 days, got my GN out of the drawer and went to put the SIM back in my GN.
1. GN would not turn on initially at all. No recovery, nothing. (solved)
Read some posts on XDA and elsewhere, people with similar issues mentioning a long (5min+) battery pull would wake her up. Dutifully I obliged and the phone did indeed wake up. However, battery was totally dead and phone shut back down.
2. GN will not accept charge from a wall charger when phone is on.
Whilst the phone seems to take a 'trickle' charge whilst powered off (battery charge animation is on), this is exceptionally slow. Took all night to get to about 50% charged to allow me to boot up and have a look around. Whilst the phone is powered on, it will not recharge. tried all sorts of official and other USB and mains cables.
3. When connected to a PC via USB, will accept charge, but error message notes that USB Device not reconised, troubleshoot? etc...
Phone won't mount. Status says it is charging over AC.
So what's up? I assume the battery died big time over the 4 days i left it. A have a new official battery in the post to resolve but... didn't anticipate the issues with USB connection etc. Worried the phone might be partially bricked/borked/knackered.
Phone is GSM 16Gb currently on 4.0.2 and totally stock. So no tinkering to date has caused this. Only event that proceeded the issue was the full battery drain.
Any hints / tips / info / moral support gladly accepted.

Really sounds like you're phone was already borked, just waiting for the right time to tell you. You might've hurt it's feelings.

Sounds like it's emotionally scarred from being abandoned for another phone and left in a cold dark danky drawer for half a week.
Have you tried reinstalling the USB drivers?
Also could try factory reset as well as try unlocking it and relocking. Worst case, send it in repair, just tell them it's heartbroken.

Heartbroken, I like it... Worse still I was testing out a Windows Phone. What a phone philanderer I am.
The drawer was nice and dry though I assure you.
How would I install USB drivers?

Assuming you're on a windows since you called it a PC..
Try and see if windows can install it for you.
Go to Start > Run > Enter "device installation" in the search > select "Change device installation settings" > Select "Install driver software from windows update if it's not found on my device"

Many have seen this type of problems, see http://forum.xda-developers.com/showthread.php?t=1427539
It's a hardware issue, but is fixable if you want to change the USB port yourself

Thanks.
Then post you link to seems to be about 'phantom' charging when no cable is connected. This is the opposite in a way - it won't charge when turned on at all.
New battery arrived today. No change. Device still trickle charges when powered off, but doesn't charge on mains power, and still will not recognise when plugged into an XP or Linux machine.
Gonna try a factory reset and will update.
Let me know of any ideas and or people with the same issue. I'm still of the opinion I haven't seen a thread with this same issue. Would be happy to be corrected.
Cheers

Well, a factory reset did nothing...
Stuck...

If you read the thread, many have had this exact problem, including myself. For me the phantom charging happened a while after it refused to charge.

What the actual ****...
I just tried what can only be described as the 'toothpick trick' : pushing down the connector nub inside the USB port on the phone et voila, now acting as normal.
I can only describe that as a really ****ty example of workmanship from Samsung.
And it would be after I reset the device as well.
Do you think this one's a definite hardware issue / defect? Seems a crazy thing to happen.

I had the same problem and search as I might, I could find no solution and had to send it in for repairs. The good news is, if you send it directly to Samsung (and dont go through your carrier), they were really fast about it and I had my phone back within a week

Lol, I was the one figuring out the toothpick trick I ordered the phone from clove.co.uk the first week it was released, and had this issue haunt me after a few weeks. As I'm in norway, I was not looking forward to sending it in, so tried to fix it myself. I tried "everything", including short circiut some pins in the plug on purpose, but what finally fixed it for me was to buy a OEM USB Charging board on ebay and replace it myself.
I know, really ****ty QA at Samsung.

Not looking forward to sitting and waiting to see if this is a recurring issue.
How much of a job is replacing the board on the phone?

Not that hard. The phone is easy to pick apart, and you can just "plug" in the new card with two simple connectors.

Turns out it is a recurring issue.
Is this the sort of thing that would be classed as due a replacement phone?

I am having a very similar issue that I believe is hardware. Sometimes charges, sometimes won't. BUT it will not be recognized through USB on my PC so I can not flash stock images unroot and lock the bootloader back up. Where you completely stock and unrooted before you sent it in to samsung? I have to find some way to get it back to stock so I can get get this fixed...

Yes, I know there are many topics on this, but mine is a little different, and this appears to be the most current thread.
I have a galaxy nexus that I got from Google IO last summer. It has worked great until last week. It stopped taking a charge. When I would plug it in with the same plug I have used for months, it would show the lightning bolt, but not charge. I tried the toothpick thing but no luck and ended up breaking the usb port. So, I bought a replacment usb board off ebay and installed that. Now, when I plug the phone in, still no charge, but my computer does recognize the phone.
Then after the 4.2.2 update, I no longer see the lighting bolt, but it still does not charge. I have been charging the battery at night. I cut off the end of a usb cable and use electrical tape to tape the two stripped wires to the battery. But that only provides an 80% charge and doesnt last the whole day.
1) Not a usb port issue, but might be a motherboard issue?
2) Not a toothpick fix
3) Maybe a software issue?
4) Maybe time to buy the Nexus 4?

[Q] Charging problem

I know, a lot of posts about it, but my issue is a little bit different.
First of all my GNex (originally on AOKP but get on stock a couple of days ago) charge normally when powered off.
Not really normally, because the animation of recharge makes a strange loop:
1) full battery with the lightning symbol for about 5 secs
2) charging animation loop, 15-20 seconds
3) black screen for about 5 seconds (it seems to "turn off")
4) back on step 1) and so on
This way i'm able to full charge my battery
When turned on (even after hours of wall charging, stock charger and stock battery btw) it ALWAYS shows 85% of battery.
It cant be charged, by wall charger or a pc/mac cable - AND it can't be seen by Mac/Pc - with debugging turned on of course.
Have i got to assume that is still a hardware issue (i checked the connector position as suggested in a tons of forum - it's perfectly centered and there is a space between the pins and the bottom of the connector)
How is possible it's an hardware issue if is charging while powered off?
Another question. If i unroot it, will the samsung official warranty repair my gnex?
thanks in advance

Yes. Just flash stock again. On your subject, I would just return it. Have you tried replacing the battery?

Yes, a friend's GNEX battery have the same issue (and the wall charger too)
I bring the phone to an assistant service in my town (just for a look about the connector).
The guy told me that it seems ok, for him this is a software issue or maybe an internal hardware
My problem is, how can i unroot my gnex without connecting it to my pc (fastboot doesnt work, tried yesterday)????
cant find a solution for that

I experienced the same thing you're going through bro.. And i can assure you that the problem lies with the software. Here's what i did.. If you are rooted.. reboot to recovery and wipe battery stats.. And see if that works.. If not, i also tried taking the battery out for 5 min. good luck

Battery Help

Hey guys I have had an issue every since I calibrated my battery. My phone does not charge. At first itll charge then it will show that pop-up that the device is not connected to an outlet when it really is. I dont know if this helps but the battery icon shows the charge flash like the thunder little icon and then goes away. Should it be flashing when it charges or an constant thunder sign? Any help greatly appreciated.

Any help guys this is really pissing me off!

Is there an option to wipe battery stats in your recovery? If not, do a factory reset back to stock unrooted, then do a factory reset and wipe, and see if that helps..

First the obvious, have you tried different outlets/plugs or a different cord, move the jig around a little, might be defective port (little hole you plug the metal into) lol.

I have tried different plugs and outlets. It will charge so slow and I think thats because its constantly charging and then not charging and then charging. Like the icon in the battery will constantly flash.

Did you try a different cord?

I tried a different cord and battery and same problem. Im starting to think its the charging port flaw. Does anyone know a place to get that fixed in NYC? Also should I try reverting back to stock and unroot and all that and see if that has an effect?

If you never had the problem before calibrating your battery, then yes. Make sure your wipe the cache and do a factory reset after you odin back to stock

Bricked phone?

Hi,
I have problem with my Note II. I was running Omega rom for 2 weeks without any problems but today in the morning I could not to charge my phone. So I turned off the phone to charge it while is off but when I connected the cable, phone immediately booted (it is bug of rom). So I flashed CyanogenMod. Now Iam running CM11 and when I connect phone to charger it shows me that it is charging and LED diod is lightning but it doesnt charge phone. TWRP recovery also cant charge it. I tried to connect phone to PC and with Odin flash stock rom but PC doesnt recognize my phone although on the phone is showing that it is connected (drivers on the pc I have installed). I really dont know where is problem. Sorry for my bad english, thanks for help.

1. Did you try other chargers?
2. Did you try other cables to pc?
3. Is it possible you have damaged the usb port?
4. Do you have an external battery charging device? Will the battery charge?
5. Do you have a second battery? Any difference?
If you've damaged the usb port then either replace it (I'm not sure how big a job this is but typically it's not a big job, depends how and what it is joined to.)
Or get a second battery and external charger.
I have ignored software issues. I'm not sure what has influence over charging, but certainly the kernel is involved - you've change rom and kernels. The bootloader the same but without odin or some indication it could even cause the issue changing it is by other means isn't a good choice. If you can get a 2nd device, visually inspect the port to see if its damaged, do the same with the charger.
Good luck

1. yes
2. yes
3. I dont know, but on CyanogenMod is LED diod shining and phone can detect that it is charging, but in fact it doesnt charge it. And OTG is working too, so I think USB is not damaged.
4. I havent any external battery
5. I tried my second battery but it is doing that same, phone is not charging.
I think it is maybe software brick or something similar and flashing stock rom I think maybe can help but there is problem that PC doesnt recognize my phone so Odin cant find device too /drivers I have installed/.
Thanks

If your only indication that this is a software issue, is that you get a response but no charge; I wouldn't be surprised if a damaged charging contact did that. Also, the battery contact points are worth inspection. If you ever got these things wet and didnt dry them straight away rust starts and never stops.
You should change your thread title, when someone sees brick they think off and won't switch on. Your title should, "Can't charge battery; odin won't connect"
I agree it could be a software issue, but apart from trying other versions of odin (3.0.7 & 3.0.9), on other pcs too; the only other solution to software issues is JTAG. Which isn't really a solution for most. Anyway, again good luck, oh and press thanks rather than say it

Tablet is always "charging" even when unplugged

Hello, all.
I have a friend with a Nexus 7 2013 (WiFi) that she recently purchased refurbished. After some issues with the charger that they originally sent with the device, she finally got it charged and now it always says that it's "charging" even when it's unplugged. She tried doing a factory reset, but even after going through all that, it still says that it's charging regardless of whether it's plugged in or not. I also recommended she try letting it drain totally to zero and then charge it again to see if it was something it could be tricked into forgetting. I also went into the stock recovery and cleared the cache, to no avail. It is fully updated to Lollipop 5.0.2 with a locked bootloader and stock recovery and seems to be in good physical condition. If anyone has any suggestions I would really appreciate it.

Curious if something could be goofed up with the wireless charging coil.
When you go into the Battery screen (two finger swipe down from the notification shade, tap the battery icon) what does it say at the top? If the battery icon shows charging, it should list how it is charging in the battery screen, AC, USB (I think) or wireless.
Another suggestion might be to unlock the bootloader and flash the factory images direct from Google. I know you said that a factory reset was done, but I'm guessing it was done "onboard" without a PC. Reflashing the entire image could help clear up any cobwebs.
Unlocking the bootloader will induce a factory reset, but if one was already done, it seems like your friend would be OK with trying it again.

@fury683 I tried checking the battery stats for which charging type it believed it had and it says "over USB" so I guess it thinks it's plugged into a computer (probably due to the low (lol) amperage). I'll talk to her and see what she thinks about unlocking the bootloader and flashing the factory image, but she bought it from Amazon so I think, unless someone else can think of anything to try, I'm going to recommend she tries to get it replaced because Amazon's CS is awesome. Thanks for the pointers. If she doesn't have any luck with Amazon, I'll proceed from there.

If a return/exchange is possible, I'd go that route. As for unlocking the bootloader, it can be relocked when you're done flashing the factory image. However once it is locked, unlocking it again will require another factory reset.
Having it unlocked allows for flashing of other ROMs and recovery, as well as easy rooting. If that isn't needed and the user is OK with waiting for OTAs (the 5.0.2 one seems to be taking quite a while for some users), relocking it would be fine.

Did anyone figure out this issue? My nexus 7 started with this exact problem this week. Always shows charging (usb). It will never fully charge, via wall charger or wireless.

I had a 2013 Nexus 7 and it did this when I took it out of the box. It seemed to be a hardware issue. I was able to warranty it with Google. Sorry this is probably not helpful to you since the warranty period is probably over, but at least it probably brings conclusion to your issue.

I was luckily still under warranty, hopefully the issue will be resolved.

My Nexus 7 2012 has the same thing. I tried to replace the USB port, but got no luck. I tried to remove the battery wires too. I think this might be a issue with bootloader. When I plug it on my PC, nothing happens.
