[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?

[Q] EXTREMELY weird issue! Any fix?

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:

Think my phone is bricked now :(

My phone won't turn back on or charge anymore. The last thing i did was pause Google Music, then the phone just sat there. It wouldn't go to the home screen or anything, it froze. I pulled the battery and now it won't turn on or charge at all. Won't display the battery charging when i have it connected to the computer or wall. Can't enter fastboot either. I'm currently at work and the computers here wont recognize it when i connected via USB.

mhm motherboard sudden death..? it doesnt seems to be a brick.

I doubt it's bricked. Will it start up into the bootloader?

Again, try pulling the battery for a few minutes. Then put everything back together but wait until you have access to a true USB charger, not a USB port on a computer. I've noticed with a few phones in the past (GNex included) that sometimes when I had a bad crash and the phone went unresponsive, that trying to get a hint of life while using a USB port didn't work as well as a charger. You'll probably have to leave it plugged in for a little bit, but after 15-30 minutes you should once again at least get the white battery charging icon to display front-and-center if you give the power button a single push. At that point, try booting into fastboot, then recovery and clean things up a bit before rebooting into android (Wipe Caches, Fix Permissions).
If not, seriously, do everything again, and wait with it charging overnight. I had a similar issue with my Nexus 10 after doing my first unroot and flashing on it. It took nearly an hour, but then I finally got the charging icon (in that case though, a battery pull wasn't feasible).

Yeah i tried all of that since 1 pm yesterday, that's when it just died on me. I have left the phone charging for over an hour and still don't get any sign of life, not even the white battery charging icon. Left the phone charging overnight, that didn't work also. I tried the OMAP fix but that also failed, it isn't recognized by my laptop.

That's a bummer. Once I had an Epic 4G that I also thought was bricked but the "leave it charge overnight" method worked even though the charging led wasn't on at all. I'm surprised that I now have seen an actual thread with a truly bricked device, not the usual "my phone is going into boot loops its bricked!" thread. Sorry to hear it man.
This may be irrelevant to you, but mine is on verizon and was having charging problems. I went into one of their stores and they had a replacement on the way in under 15 minutes of me coming in. Great service from them if that's who you're with carrier-wise.

Everything was working perfectly on mine, the battery was at 80%. I'm with T-Mobile and i know they don't carry the Galaxy Nexus. Would a Verizon store let me check if a new battery will be turn it back on? If not, guess i have no other choice but to call Samsung =/

[Q] Note2 not charging, connect(ed) to PC.

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

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.

Pixel XL3 wont charge at all. Turns on/shuts off

Hello im new to the forum, a friend of mine suggested this is the best place to post this so here it goes:
I bought a used Pixel XL3 from ebay, it arrived today and i immediately turned the phone on, it had about 25% battery in it, i used it for most of the day, when i got home i tried charging it with the original charger and when i connected the phone it didnt show it was charging at all. I tried 2 other charges/cables and the same result. I know the phone did detect the cable was being connected because every time i connected the usb cable the phone kind of blinked, but it didnt charge.
I researched on Reddit and someone witha similar problem suggested i completely drain the battery and then try and charge it again. I drained the battery and now when i connect the phone it shows a gray battery icon with a lightning bolt in it for a few seconds, then it boots to the google logo and then it shuts down again. It does this over and over again.
Im at a complete loss of what to try or do next. The phone did work when i took it out of the box! I cannot RMA it to Google since im not the original buyer of the phone and im also out of the US.
Any assistance would be really appreciated!

Try a wireless charger?

If you plug it in when off does it charge? Leave it charging for as long as you can then boot up.
I've had this problem and although it seems like a software issue there's no solution in sight and many people experiencing it.
Once you have the phone on check for a notification that says "Charging connected device via USB" - choose that - select "This device" (instead of "Connected device") Not a fix, but I"ve been getting by doing this and it allows me to charge. I am close to getting a replacement.

Welcome. Both ideas of turning the phone off and charging from there, and wireless charging are good ones. Once you get a decent charge on the battery, go into Recovery and do a factory reset. If the problem presents itself after a reset you may have a hardware issue like the USB port itself or the battery. If the phone is bootloader unlocked (or unlockable) you may have a few more options. What are the first 2 digits of your IMEI?

I'm having the exact same problem with my Google pixel 3 XL. I don't know if it's the charging port or it's because I'm running Android Q beta 4 and it's been happening for 2 days now. I'm going to try a factory reset tomorrow night if nothing else works then I'll update it here.

Ok, so have you tried wireless charging to rule out the USB interface? Hopefully a fresh install with latest P will get you back up and running.
