Hi, I have been trying to google for this issue for around 3 hours now and could only see one post that was remotely similar but offered no fix, so here goes, I am reluctantly posting.
Bought my Galaxy Nexus second hand last week and everything seemed fine, but decided I wanted to go stock (it was rooted when I got it), so I flashed stock IMM76i, but left bootloader unlocked.
After doing this, I got the dreaded signal loss issue, however it was slightly different. Signal was fine when the phone was on standby, but if it was connected to a wall charger or PC then it would lose signal in standby. I then heard that some people had got around this issue by going back to 4.0.2, so I did this. Still had the same issue.
I was getting sick so I left the phone for a few hours and used my Sensation but came back to the Nexus last night. I thought, 'mm, I wonder if it is still doing the same?' so I connected up to my laptop and it did not lose signal . However, on second check, I realised that it wasn't detected by the PC at all. No MTP, no driver popup, nothing in device manager, and not even charging!
Panicking, I ran upstairs and got my wall charger, plugged it in and the phone started charging. I then tried another USB cable (a one that was charging the Sensation whilst all this was going on) and again, nothing at all, not even charging when connecting to PC, but charges fine when connected to wall. I tried 2 different PCs, both of which worked fine with the Nexus 3 hours previously.
Here is the weirdest part. When the phone is switched off and connected to a PC, the computer sees it, installs the driver and it charges! The little white battery pops up. Also, the phone works perfectly fine in fastboot mode as I have since locked and unlocked the bootloader as well as installed 4.0.4 again, all having the same effect. So, the scenario:
Wall charger charges the phone
USB Cable connected to Windows and Linux doesn't detect the phone at all including charging when phone is on
Phone is detected by PC whilst off and will charge
Fastboot mode works perfectly
Signal issue seems to have resolved itself
This phone is driving me crazy
I need a lie down!
Apologies for the long post, just I am at my wits end about this. As I bought it second hand,I would imagine I wouldn't be covered by any warranties offered on the phone.
Thank you in advance if anyone knows how to fix this. I would imagine it won't be hardware as it works fine when the phone is not booted into android, but the wall charger also works fine, and the usb cable works with other phones.
It was this way before you went back to stock?.. Try a custom rom also..
Galaxy Nexus AOKP m5 Franco kernel m3
Could it be an issue with
a) the drivers on your pc? (Try reinstalling using the GN toolkit)
b) the voltage of your usb ports on the pc? (try using a powered hub).

a)Drivers should be fine, fastboot works perfectly. I would have thought that even without required drivers, it would still pick up a charge ?
b)Tried multiple PC's that the phone used to be detected on and pick up a charge, can't imagine they would all be broke. Will try a powered hub abit later when I get home

No it wasn't like this when I went stock, but it also wasn't like this for the first few hours I was stock, as this is when I had the signal issue. It was after leaving it for a while that the issue developed.
Thanks for the quick replies! Keep them coming
Well, you're not alone that's all that I can say, please don't let the conclusion of my link devastate you, the technicians in my country are idiots.
My switched off GNEX charges from PC only for few seconds and then restart the charging again. It's as good as it's not charging (can you confirm the same?)
the issue lies in ur KERNEL. try flashing another kernel in Android Development section, or switch ur ROM to third party such as AOKP or Slim ICS. It solves the problem, I promise. if u want to remain stock, I cant come up with another idea because flashing ROMs is always a fool proof method

Hi, thanks for that. I have just got my phone back from our technician and they found no fault! I tested it and it didnt work for me so rang them and they said they only tried charging from the wall charger not USB!! So 1 week and nothing! It is now going back. I have just tested and, when switched off, it charges continuously.

Tried loads of different roms, including AOKP and Tablet hybrid. Both had issues as well.
So what happened eventually? PCB replacement? :fingers-crossed:

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?
I've seen this problem mentioned before, but no good fixes.
My phone won't charge while on, but will when off. Charging has always been a little buggy, but now seems stuck this way.
The problem seems to keep my phone from connecting to the computer - neither the mac android download program will recognize the phone, nor will it charge off the computer, nor will the wugfresh tool see it when plugged into my PC.
I rooted/unlocked using the wugfresh tool (kept the stock ROM) and figure I need to warranty replace the phone - but because the computer won't recognize it, I don't know how to un-root/re-lock it.
Question - 1. anybody know how to fix my usb charging/recognition problem? 2. assuming not, is there a way to un-root/re-lock the phone without needing to plug the phone into a computer?
Thanks very much!
Does it charge with the phone on from AC? And when it's plugged up to your mac, does it have the thing in the notification bar saying its connected?
It's possible you have a bad cable, just to eliminate the easy fix first. It should charge fine with any mini USB charger.
If you can get it to charge from AC, I'd try a different computer if possible or if not maybe a re-install of the drivers.
Next, as maybe a last ditch effort, it's possible the ROM got corrupted, though I'm not sure how likely that would be. I'm sure you can get the stock ROM to flash in Clockworkmod but the only way to re-lock the bootloader that I know of requires a PC.
Maybe someone else can chime in weather or not Samsung actually cares if you're unlocked when it comes to a warranty for a hardware problem. Also, what carrier do you have? They may just give you a new phone themselves and again, maybe someone can tell you if they actually look at whether you've modded your phone.
Thanks for the reply.
Yes, when it's hooked up to an AC adapter and the phone is ON, I get no charging. When the phone is on and hooked up to a computer (both PC and mac), I get no charging. No upper right hand corner battery indicator change.
In fact, when the phone is off and hooked up to AC power, it seems to be hit-and-miss as to whether or not it actually charges.
Plugged into a computer, I get nothing - it doesn't register a device is attached at all.
I think that's a great question - if you return an un-locked phone, do they definitely get mad at you? I wonder if that's been asked in the forums before...maybe I'll make a different thread?
Also, from clockworkmod, how can I flash the original rom, as you suggested?
I've already factory re-set the phone and even flashed a different ROM just to see what would happen - and it didn't fix the charging issue.

I literally had this exact issue over the weekend where it would charge when powered off but then the USB would completely die when the phone was turned on. All after using my incar charger. It seems the port inside the phone got bent so that the board inside was almost touching the bottom of the phone. If held flat on your palm...
I fixed it by bending the board back up with a knife so its dead in the middle of the port. No problems charging now.
this exact problem has been an issue for me as well, contacted Samsung and told them i bought it second hand and they issued a rma and sent me a ups label t send it in. This is my first phone that broke before I even had a chance to root it. I was pissed at Htc so decided to try something new. Going back to my T-Bolt for a while now.
My phone charges sometimes, others it doesnt. Sometimes the "Nintendo blow" works, other times it requires force. Eventually I can always get it to charge, but it can take a half hour of playing with it. I have multiple cables, original Samsung batteries, and lots of experience inside phones, and have never had an issue that I couldnt FULLY determine was hardware or software. Samsung claims they have never seen this issue. lol. Obviously they dont visit the forums

great idea - i was using my car charger this weekend. i'll give it a shot.
update - i bent the little board up off the bottom, and now i can't fit the charger in it. uhoh.
This is becoming a bigger and bigger issue. Please star and/or comment on this issue: http://code.google.com/p/android/issues/detail?id=23789
I sent my galaxy to Samsung 2 weeks ago, it is due to arrive back today. They paid postage each way and the invoice says they replaced a component (no detail) and updated software and prl. I was already on the current release so not sure what to expect. But it is good to know they are taking care of us.
Hi,
Yesterday my new (~2 months old) Note2 stopped charging. tried 2 different chargers, 2 different cables connected to PC. No reaction (no beeps, no led, battery icon not changed to flash).
Tried removing and putting the battery back in. No change.
On the other hand, when connected to the PC, the PC identified the connection and allowed file transfer. Later the battery died completly. I succeeded in booting to download mode, and again PC identified the USB device.
Switching the phone on with no battery gave no results either (would not turn on).
This leads me to a conclusion that the USB port is probably OK. Could it just be a dead battery? (according to its label, the battery was made on Nov 29th, 2012).
I will be able to switch battery tomorrow with another Note 2. Anything else I can try till then?
Using custom recovery and stock rom.
Thanks in advance,
Idan

Yeah, with or without battery... no reaction from the phone.
Have you tried a lower powered device to see if that works? Some usb ports don't have full power output, as some laptops portray.

I've tried 2 USB ports on a desktop PC. didn't work.
I've connected it without the SIM and SD to an old nokia charger (0.7ma), no sign of a change but after ~ 1 hour I noticed the red led turned on - turning the device on showed 44% charged.
Now I am too puzzled. any ideas?
This is exactly what happened to me. .. it was the motherboard. I brought an external battery charger, charged the battery full so I could use the phone. Then used triangle away and odin to flash stock rom, and sent it in for warranty service. This seems to be becoming a common fault with the note 2 now....ive seen a few thread recently.

Hey there, my sgn2 n7100 had the same problem before, I tried everything, even disassembled the phone apart, but it was still won't turn on or charge, won't be recognized by pc or Mac. One day when I repaired my mom's iPhone 4 touch screen, I found out that the USB port was so dusty. I thought may be it's all because the USB port was dusty then I picked up my sgn2 and used a soft tooth brush with a little pure alcohol to clean every corner of the USB port. Guess what? After 15 minutes I connected my phone with the USB wall charger, my sgn2 just started to charge again. Trust me guys, try to use a soft brush to clean the USB port before you give your phone to the repair store or somewhere else. Good luck!! Hope it helps.
Same here, i manage to purchase note 2 for 300 euros! And when I put it to charge nothing!I went to download mode and then turn it on normal and its charging! Also happend the same with my s3 so eighter its a charging problems or seems to be one software issues
Sent from my GT-I9300 using Tapatalk 2
@scufutz I could guarantee the symptoms described by the OP is NOT software issue, as I have an N7100 with same problem and I managed to flash new kernel and still it does not charge even powered off. Download mode connects perfect.
I'll check if this cleaning method, or if its a circuit prob.
A few hours ago I noticed that the phone wasn't charging even though it was connected. So I did a few experiments: I put into into three different power outlets, I tried a different charger, I connected it to the computer but nothing happened (the computer didn't even recognize it). Then I decided to turn it off and try again, and these are the results: the screen turns on really often to let me know that it's charging, there's even the charging animation, but if I try to turn it on not only it isn't charged, but it doesn't seem to recognize the charger anymore.
There are a few other weird things, though: I use the XenonHD ROM, and once or twice when the phone was unplugged the battery icon was still "moving" as if the phone was charging, but the graph said that it wasn't. This probably is just a bug, but maybe it meant something.
My best guess is that the micro USB port is broken, but maybe you guys can help me with this?
Just like you said, your usb port is broken, propably a short circuit somewhere. But changing the charging port flex ribbon is very easy, even for a first timer (like I was/did a couple of weeks ago)

Same problem, but I haven't reflashed or done any sort of recovery. Problem first occured a few months ago after latest 4.3.0 update. Phone would only charge when plugged to USB or phone off. After a few hours the problem fixed itself. The only thing I did was revert back to stock launcher since it seemed like my custom launcher was using way too much memory at boot. Rebooted and the phone was charging. But honestly I think it was just a coincidence. Luck.
Thought the problem was gone but it happened again two days ago. I let my phone run dry (didn't have anywhere to charge). Got home plugged it in and it charged when off but not when booted. I have concluded it's software related. Chargers and USB cables all work, my different batteries work and micro usb port is clean. Device will charge when connected to PC in most modes but PTP works best (don't know why). PC doesn't regognize device however so I can't access it.
What fixed my problem was installing Wugs Toolkit for Nexus. I don't know why but it seems like when it was installing all the different components to communicate with my device it got it to work again. My device was connected to the PC during the install and suddenly rebooted by itself. After that everything was working perfectly.
Sadly I forgot to charge my phone overnight and it ran dry again and today I'm having the same problem again. Looking for a definitive fix, any suggestions are welcome.

My computer detects it as "Unkown device", but most often it will charge in PTP mode. Also, leave it connected to the PC for about 5 minutes. That's how long it takes for mine to start charging sometimes. This is just a temporary solution to actually charge the battery, but I'm sure we'll find the problem
Nope, mine's not charging while off or in PTP mode...

That really sucks, I wish there was a way I could help.. For the time being you could buy an external battery charger (not expensive), but that means having to take out the battery every night Otherwise there is always the hardware options like changing the USB port or the main board. Have you tried pushing the tongue inside the micro usb port up towards the middle? This is a known issue on the GNex and causes connection problems (because the slot is badly engineered)
There's one more thing I'd like you to try. Plugg your phone in through usb to any computer. On your nexus go to the dialer and type *#*#4636#*#* this will take you to the testing menu. Select "Battery information" and tell me what the top 2 lines say. When I'm plugged in with the wall charger it just says "Not charging" and "Unplugged". However when I connect through usb I get "Not charging" and "AC" or if I'm lucky "Charging" and "AC" which shows that the phone detects some sort of input.
