[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?
Sent from my Galaxy Nexus using XDA App

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?

Galaxy Nexus not charging !!

My gnex is not charging..i plug in and the battery symbol doesnt show charging..when i check battery in settings it shows not charging instead of discharging.
Another thing is that if i switch it off and plug in the white charging symbol occurs but after an hour when i switch on the battery is at the same percentage..
pls help :'(

Ive had those same issues..I went to charge it on my car charger and it instantly began working. The very next day I tried my hone charger again and it would work..Crazy thing is when the home charger wasn't working for my GNEX, it would charge my girlfriends phone just fine!!

Have had a charging issue as well, and solved it.
Hey there,
my SGN was not charging at all not even when turned off, started two days ago, the first evening it was only charging on one out of my three USB cables (each cable has its own wall charger).
Also my PC with "Win 8 Pro" was not recognizing my phone at all.
My first try was a bit stupid, but it worked, well for one day only. I bite on the USB cable, so the part that goes in the phone was a bit deformed, and the SGN was charging again. \o/
Next evening, I had the same problem again, but this time, non of my three cables was able to charge, even after further deforming tries.
My final solution was to use a needle, stick it in the USB port on the phone and bend the small "tongue" a bit up, so it was exactly in the middle.
My Phone was off and the battery removed. I put all together again and plugged the USB cable back in, it started charging while off.
Then I just turned it on, after booting was almost done, my PC told me that my SGN is connected and it was still charging.
I removed the cable, plugged it back in, several times, also on all three charger with its cables, finally my problem seems to be resolved.
btw. My SGN is from November 2011, so one of the first here in Europe.
I hope this can help some other with the same problem.

I had the same problem, GNex quit charging. Fixed it by using a toothpick to gently move the "tongue" in the USB port up towards the LED (screen side). I used a wooden toothpick as I didn't know what would happen if the connectors shorted using something metal.
Apparently, moving the USB plug around when it is in the port can move things out of alignment. Very easy fix, takes less than one minute. You could use a plastic pen cap or whatever you have lying around as a tool.
If you are under warranty, you could always ask for a replacement.

I had this problem a while back, first only some chargers would work and finally none of my chargers worked. In my case it seems like the problem was pocket lint tightly packed at the back of the usb port. The lint was grey and so tightly packed that I couldn't see any thing wrong. I used a fine tooth pick and got a good size wad out and the charging problem was solved. I always thought that the lint prevented the usb cable to be fully seated but maybe I bent the "lip" while trying to get the lint out

Well, I've left my phone on charge with the adapter charger and it was recharged. Now it seems to work also through usb

I got a new Gnex today because of this same issue. It would randomly not charge no matter what charger is was using. What's weird though is I never had an issue transferring files to my Mac and vice versa.

had the same issue, was charging only on PC-USB, I used a safety pin and removed a lot of lint. Works fine now.

Thought that was lint but in my case even removing the lint it wont charge CORRECTLY -- with the original charger (it was uncharging after some movement).
Then I realize that forcing the usb plug to go more inside the USB port it works. What I did: Removed the black protection because it block the plug to go more inside the phone port. It's now metalic (lol) but not a problem of charging anymore.

I'd buy some heat shrink tubing for that before you cause a fire .

Sometimes it happens to me when battery's charged at 98-99%. Don't know the reason, and what I can do is to remove cable, reconnect it

Unfortunately, all that really does is shorten the battery's life. There is no benefit to forcing it to that feel good display of 100%.

Here's my full experience with my Galaxy Nexus charging problem --
I bought this one eBay, came with 4.1.2. Didn't even test charging before I updated it to stock 4.2.2 and rooted it, so I'm not sure if the problem developed after my software update, or if it always had that problem. The eBayer said he didn't know anything about it. I'm on stock rooted 4.3 now, and the problem persists.
The phone has never charged on any of the several AC adapters I've tried. These have been between 250ma and 1A, and they wouldn't work whether the phone was on or off. It would consistently charge when connected to my desktop computer, but that all changed a few weeks ago when I changed out my computer's power supply. Now, the only one trick I've found is to turn on WiFi, BT, GPS, and put the screen at 100% brightness, then plug connect my computer's USB cable, and it will go into charging mode about 35-50% of the time. This works OK, but one extra annoying bit is that when the battery reaches 100%, it stops charging, and won't start again until I do my little trick and replug the USB.
I tried replacing the USB port, but that didn't fix anything. As far as I can tell, that's the only part that can be easily replaced by a normal person. I'm basically managing this by swapping in batteries charged by an external charger.

Got major issue all of sudden and phone won't start anymore
I have been tweaking with my phone customizing it for like one year and didn't had any problem. I flashed with KitKat gummy ROM and then reverted back to 4.3 stock jellybean using ROM manager installed previous saved 4.3 stock rooted ROM.
Further installed clean master and did some advanced cleaning of cache files. WELL after reverting back I started witnessing some major flaws with battery charging status earlier with KitKat I wasn't using any battery saver app but after reverting back to 4.3 I installed DU battery saver and it would like take ages to charge my battery like 7-8 hrs but I wasn't paying much attention to this. I did some advanced cleaning with clean master, but anyways that won't clean any system files that would hinder the functionality of phone right?Problem started cropping up as I detached my power cable without switching off the supply ( even though I had done this previously many times before) , phone flickered/froze and switched off and won't start without external power supply even though i had 57% battery charge that too showed random status, sometimes 0% and sometimes 50+ %. This went looping for sometime then like it won't switch on even with power supply, just showing for a sec the battery symbol with bolt sign when the charging cable is inserted and going blank within 5 sec . It would show the battery icon sometimes and sometimes no sign just plain blank..
Well I tried different ways as suggested like pushing the small tongue inside USB to middle or attaching to laptop w/o battery and putting back n starting but all in vain, no response.
I am not sure any major fault has cropped in the charging circuit or is the phone bricked? Battery dead?
Guys do give some suggestions.. I have been charging using diff usb cables, no response but just that battery symbol for 5sec n going blank..even though i have been charging the phone is getting heated..but does that imply anything?
do provide some insights guys
Thanks in advance!

[Q] Phone says that it's always charging?

I don't know how to go about this, because, to my knowledge, its not effecting the phone in any way. Maybe a little drain, but that could be 4.2's problem. But regardless, my phone is always "on charge" no matter where I am. On any ROM this happens, so I know its a physical thing. I've been told that you can use a knife to push the contact up a little, but that only works until I plug it back in the next day. So...... Any thoughts on how to fix this without replacing the charging port? (To my knowledge, that involves soldering very small parts.)

Well if it worked by bending the contacts up but goes back when you plug it in. Have you tried a different cable? Also have you cleaned out your charging port?

Agreed. At this point you could be having issues where you can't see it, such as where the port is connected to the board.

Had to take port completely off before i noticed... Sprayed with acid (not recommended) and cleaned it, rinsed it, soldered back in place = good to go..... For now

Hi jeep, i have a similar problem but i'm not sure it's the same, i happened a few days ago when myi changed the battery and pugged in the charger, i noticed there was something strange, the phone's screen showed the battery was charging before i pugged in back (just when i placed the new battery). Now it behaves as it's always plugged in charging just when placing the battery in, the phones is turned off and the screen shows charging battery icon (i've tried 2 more batteries), and also there's no usb connection to the PC either.
It's a very bothering problem, the phons won't go into deep sleep, and the screen goes to the screensaver all the time (as it where pugged in charging)...
I always repair my own electronics, months ago i replaced the power button, do you think it could be a bootloader issue or just the micro-usb port?; when you fixed yours, do you think i should take it completely off and resolder?
Any advice will be really appreciated!!

Galaxy Nexus Won't Charge

Hey Guys,
Over the last year or so I've had intermittent charging issues with my Galaxy Nexus. About 4 months ago is when it first started happening, the phone would either not charge or only charge when it is turned off. Somehow the issue was resolved through tons of troubleshooting, I'm not even sure what fixed it or why it started working again.
Same thing happened about 2 weeks ago, except this time it won't charge at all. Then 2 days later all of a sudden started charging again. Now it's happening again today, I have no idea what is going on or why this handset won't charge properly. The phone won't turn on with just the charger in and the battery out either.
I've tried various chargers including the OEM charger, I've tried up to 6 different chargers and 7 seperate micro-USB B cords. Nothing. I've tried a brand new battery that a friend bought for his phone before he threw it in and no results.
At this point I think it's the USB charger board, however I'm not sure why it would not work and then work again. Does anyone have any ideas or any solutions? I've read thousands of threads on this, from this forum and many others and have gone through some ridiculous troubleshooting methods.
SCH-I515 Korean Version.
Seriously, anyhelp is appreciated.

As of now, all of a sudden it will charge while it's off. But only to about 4% then it just stops charging. It will not charge while it is on at all.

Because it's getting worse and worse?
Relock bootloader, and return it in for warranty, if you can. I'm afraid there's not much help if you already checked for damage to the USB port.

hi
had the same problem until a few minutes ago.
received my usb/charging flex part today and changed it just before to post here.
took me like 20 min, really easy to do, everything works perfectly and i also took time to clean up a bit the phone inside of some dirts and change the housing i bought with the flex part.
As my screen is under protection since the beginning (4 months old), and that i recently bought a 2000mah battery, well i have to say that i have a new phone ready to handle the new year easily!
operation is easy and you will find plenty of videos on youtube showing how to change the usb flex (7€/$ , +/-) so pretty cheap.
Good luck

Why not buy an external battery charger and a spare battery?

I'd get a replacement daughterboard and switch it out yourself. It's easy dude, just like a previous poster already said. I just did it myself, took me all of 20 minutes and cost me $10. ifixit.com has a step by step direction sheet, if you have any questions feel free to contact me about it.

Try the following:
1.) Turn off your phone.
2.) Get a flat head screwdriver (small one)
3.) Push the flat connector inside the microusb port up. (It often gets bent downwards because it's so thin compared to other phones...)
4.) Boot into the bootloader
5.) Hit volume down until restart bootloader appears. Press power button.
6.) Start phone manually.

i dont know why, but this fixed it for me, for a short while. now the charging is intermittent and seems to come and go as it pleases.

Hi,
I had the same problem of ghost charging, it started with phone not charging when connected to charger and then randomly showing charging...
Now discovered it causes vbus_tuna_otg wake lock, resulting in high system usage in settings> battery and not letting phone go to deep sleep, causing battery drain.

Same Problem
I've come into the same problem with my Galaxy Nexus as well. If my phone is turned on, my phone will recognize that a charger is plugged in but the battery will not charge at all. If the phone is off and plugged in, the charging screen won't appear. I've tried multiple chargers and cords, 2 different batteries, and even replaced the micro usb and board, but the problem hasn't changed at all. I've managed to charge my batteries with an external charger but would like to get my phone back to normal working condition. Does anyone think that changing the actual motherboard itself might solve the problem?

I had this problem before, using something small and flat to push the charging connector off the housing will work for awhile. The pin in the charging port is bent down and is very thin it's easy to lift up just use a tiny bit of force to lift it up. The pin touching the housing is causing a short and that is causing your no charge while it's on and mine even went as far as draining my battery very quickly. I did research and found alot of people having this issue on the gnex. I eventually had to turn mine in for replacement, no problems since. Hopefully yours is still under warranty or you can buy the peice that is broken and replace yourself, there is a post above saying what to do for that.

Looks like my phone developed this problem. It sometimes won't charge be it via my pogo dock or USB cord. It seems to start taking a charge after I pop out the battery and then put it back in. I'm going to order another battery and see if that is the problem.

Thank yoiu!!
solved my problem!! I am in your debt

popping the battery out just worked for me too

I just did the remove battery trick as well and it worked. I just noticed my battery not charging yesterday but figured it was because I was trying to use a different charging in my dad's car. got to work where i left my normal charger and no luck.

That's good, I tried it a few times but the issue still pops up. To be fair though, I've had this phone and battery since launch day... Almost three years old. I ordered a new battery so hopefully I won't have the issue anymore... And I won't be surprised if my battery life is a little better too.

The Galaxy Nexus is nowhere near three years old. Your phone would be 18 months old if you had it since launch.

Excuse me, two years. According to Samsung their lithium batteries have a life of about 500 cycles. So my point is still valid, my battery is probably just on it's way out. I'll find out for sure when my new one comes tomorrow.

Yeah, since battery life hasn't exactly been the strong point of the GN and some of us had to go though a complete cycle daily, I suspect a lot of folks are going to be seeing more and more issues. Not too long ago, I had a battery that failed in such a way that it would randomly crash the phone and had to be pulled in order to allow a reboot. I would've suspected anything but the battery in that case.

Try the following:
1.) Turn off your phone.
2.) Get a flat head screwdriver (small one)
3.) Push the flat connector inside the microusb port up. (It often gets bent downwards because it's so thin compared to other phones...)
4.) Boot into the bootloader
5.) Hit volume down until restart bootloader appears. Press power button.
6.) Start phone manually.

This kind of worked for me, but the "boot into bootloader and restart it" killed my phone, don't know why. After a lot of a hassle i got it on, with 2% left, again not charging...tried to repush the connector towards the center and now i cant get my charger into the phone, maybe overbend it...what to do?...

I have a strange problem, my Gnex does not charge the battery, first i thought that it was the battery so, I tested the battery on other phone and it charged just fine, and then i ordered the usb/charging assemble from ebay and replaced on my gnex, and still not charging the battery, but when i connect the phone to the pc it recognize it immediately, but still won't charge the battery, anybody has an idea of what my problem is?? and how can i solve it?
Please help!!!

Charging issue, phone does not charge at all, bad USB port?

Please help!!
So, for the last couple weeks charging my Note 2 has been extremely hit or miss. It either connects and starts charging, or it doesn't at all. Sometimes, I can plug it in and leave it over night and find it didn't charge at all. Sometimes, as I am trying all sort of different chargers/options, I eventually give up and several hours later I see the screen pop to life and show a charge coming in. I have tried:
4 different cables
3 different AC chargers
2 different computers (multiple USB ports on each)
my car's USB
Seem to have no effect on whether or not it will charge, which makes me believe the issue is either the phones USB port or the battery itself.
Behavior when plugged varies, sometimes:
Completely dead - no response at all
Empty battery icon (with circle in middle) shows on screen, then goes black - never progresses to the battery charging icon (no circle in middle, green showing progress)
Works, progresses to green battery icon.
I'm currently in the first option - completely dead. Whenever I get to the 3rd one, I let it charge a bit then turn the phone on and let it continue charging. At this point it will generally work for a while but whenever I unplug the phone there is no guarantee it will work again, even right after.
Has anyone experienced this? Any experts have an idea I can try?

With this, I can at least charge the batteries outside of the phone, even if the USB port won't work. If necessary, I would need this to revert to stock before sending in to Samsung.

I had the one where you plug in and nothing, all I did was a battery pull and it worked, no issues since

It sounds to me like you have a broken micro usb port. I went thru this with my note 1. The plastic sleeve on your phone port that the pins sit in is fragile.in my case I discovered I had snapped a pin in half prevent charging, reading the phone via micro usb..I would get a intermittent connection then after a while nothing. you can try to see what happens if plug in a USB and wiggle it in all directions to try and establish contact..in any case your best bet is to go find a universal battery charger..particularly one that charges the battery itself without the phone. (it basically sits inside of a cradle and charges) the pins can be adjusted to make contact on your +,- on your battery. After a charge try it out. they have cheap ones a radio shack that do the job. Its a hassle, but on the bright side is your phone will work. Plus deep cycle charging will make for a healthier battery . hope this helps

Are you using a case on your device? If so, does it in any way encroach on the USB port?
If you are using a case try taking it off and plugging in with the stock charger and cable.
Couldn't hurt, and if the case blocks the port in any way it may be the solution.
Hastily spouted for your befuddlement

Thanks for the replies everyone, and yes I ordered the battery kit from Amazon, so I should be up and running. At least to revert to stock before sending it to Samsung. But still I would like to find a permanent solution for this if possible.

Yes, I have of course checked this For most of my testing and trying to get it to work I haven't even had a back panel on the phone.

Yes, this sounds like my problem. Battery pull fixed it for me originally too, but over time it got worse and the problem happened more frequently.
Haven't been able to get it to take a charge all day.

Thought I would update on this weird issue...
I received the Anker batteries/external charger and got the phone working again. Tested charging directly with the phone and new batteries now that it was back alive. No dice. Tested it on and off over the next couple days and still could not get it to charge. So I decided I needed to send it in for warranty replacement, but life got in the way and I continued my cycle of swapping out batteries. This is actually a really nice solution! I like having a couple fully charged batteries ready to go at all times.
Anyway, yesterday I finally had some time and was going to contact Samsung. I was sitting at my desk and decided to try charging one more time. Plugged in the microUSB cable and... IT WORKED! I have no idea why it would randomly start working again, but it has worked for the last 24 hours every time I plug it in.
So now I can't really send it in for service if they can't duplicate the problem. I'm just going to cross my fingers and hope it doesn't happen again...

Wondering if this ever started back up, or if your phone just kept on working. As my phone has stopped all together charging and needed to find a fix for this. Wondering if just replacing the usb charging port in the phone would fix this up. Has someone has done this already to fix this problem. I'm torn between using an external charger and wait for the part to come in from ebay for 12 bucks or just send it in for service and be without a phone for 3-6 weeks.

If you send it in to get it fixed I'll be interested to hear the result (and the price...!)
I've been using an external charger for a couple of weeks now. It's a bit of a pain, but you quickly get used to it.
I'm holding out for the announcement of the Note 3 and hoping that arrives sometime before Christmas!

Well it was the USB port on the phone sent it away already got it back. Telus my provider warranty'd the phone. Did get a quote to fix at a cell shop 70 buckaroo's. Personally just buy it online at ebay for 10 bucks and do it yourself not that hard. Just didn't want to wait for the part to ship and get here

Do you know the process to it... by the looks of it, it seems attached to the motherboard or is it something I can easily do thanks in advance...
Edit...
Sorry wrong thread I meant for the s3 usb port
