[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?

charging/usb port problem - can't un-root

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.

usb dead. need to re-lock, this is a weird one!!

Sorry this is a long one. Phone is a Verizon Galaxy Nexus about five months old.
Using Galaxy Nexus Root Toolkit v.1.3 I managed to get the phone unlocked and (I think) install clockwork mod but when attempting to flash to root I got as far as "install from zip file . . .' but the next option "select zip file . . ." leads to a either an icon of a hat (which I presume is clockwork icon?) or a picture of an android with his belly open and an exclamation mark in a red triangle. I can no longer get to this point to confirm exactly which. Now when attempting to get to recovery mode I get into fastboot but after selecting "recovery mode" I always get the android with his belly open and a red exclamation mark and can never get to any menu.
Now all of a sudden possibly as a result of this process or else by coincidence usb on the phone appears to be either dead or sub-functional. This may also be why I could never flash to root, (bad USB led to corrupt or missing zip?). Windows does not detect any usb connection from phone, not even a failed one (no sound, no error message) but I have confirmed it's not the PC's error as other usb connections are working.
Also, confirming some sort of USB issue, the phone does not show the charging icon when I plug it into a charger UNLESS the phone is powered off, when I do see the charging animation. To make matters even more confusing despite not seeing the charging icon or the battery manager reporting that the battery is charging the phone does appear to be charging even while powered on but this was only after one night and I'm not quite 100 % certain it charged or that it charged at the usual speed. (thankfully I have an extra, separate, standalone battery charger).
I have re flashed to factory from the " backup and reset" menu inside Android and this did not help.
Simple question: any way to RELOCK phone without USB so I can at least make the phone appear un-tampered with so I can get a warranty service or replacement to fix the apparent usb problem?
bigger question: wtf is going on, is the usb issue perhaps a software problem? and is there anyway to fix the failed flashing process by perhaps transferring a zip file by some other means than usb to the proper directory?
Thanks for anyone who bothered to read this far.
Note: the actual sequence of events is a bit more complicated and now foggy in my memory but this I hope is close enough. If anyone wants more info I'll try to supply it. Let me just say that there were issues from the start of this process. merely unlocking the phone the first time had bricked my boot, all I saw was "Google" and a picture of an un-locked lock, getting into fastboot and then choosing recovery mode led to the picture of the belly up android but after several attempts I finally got past that one time and elected to flash back to stock from recovery menu. This was all before trying to root.

No to first question.
As for second question, pull the battery for about 10 minutes and see if it fixes your USB issue. Don't connect it to a computer to test the charging issue, and instead an outlet.

Trying now, will report back. I think I already tried this though. I should also tell you I have three different batteries and behavior is same for all of them.

I'm not thinking its the battery but something stuck in hardware. Hence the leave it out for 10 minutes.

Left battery out phone unplugged for almost twenty minutes... and still no luck.

oops, I see I was supposed to put this in the Q and A section, sorry, new here, should I start over there?

Could be a hardware issue with your usb connector. Try cleaning it out with a blast of compressed air or something. I just found out today that the USB ports on the GNex are weak and prone to maybe needing repair.
Good news is that the part only costs $6.00 on ebay - if you're a DIYer.

That was it! I blew it out, and then I cleaned a bit with alcohol, and then when that didn't do it I pushed up (or down) on the cable while it was plugged in and suddenly it came to life. I was able to connect to PC and lock it back. Now at least I can attempt a warranty repair if I so decide.
I had gently pushed up and down on the cable before to try to make a good connection but never once did it connect - I feel like the cleaning must have been needed but apparently was not sufficient to fix it fully.. So I suppose something is still amiss with the connector - either it is damaged or askew or else still a bit dirty.
I'm happy to be back to full stock, maybe I'll root again another day after I sort out the USB issue.
Thanks everyone!

In the future, I'd recommend steering clear of "one-click" or "toolkit" root methods. Sure, they work, and gosh darn it they are easy... but when something goes wrong, you'll never know what's actually the problem. Get comfortable working with fastboot and adb; it will take you a long way with this device.
This should help get you started in the right direction.

[Solved] ADB Not Working, USB Port Issues?

So I found a brand new 2013 Nexus 7 at a swap meet a few days ago. An old lady's kids bought it for her and she never used it, so she sold it to me for $20! Best deal I've ever gotten, and everything works fine, except for one thing...
I think something is wrong with the usb port. It seems as if it is stuck in charging only mode.
At first I noticed that whenever I charged it, it would keep showing the charging battery icon in the status bar and say "Charging" on the lock screen for some time after I unplugged it. If that was it, I wouldn't mind, but when I plug it into my computer, it never appears under adb devices and never goes into debugging mode. It seems as if it is stuck in charging only mode.
I've checked everything on the computer side (my M8 connects just fine) and gone through developer options, so it must be the tablet. I do have an old Nexus 7 (same model) that broke, so I could scavenge some parts from it, but I wanted to see what some of you think might be wrong with it before opening it up.

Have you tried to flash a factory image? Or just factory reset it?

Factory reset was the first thing I did (a few times actually) , and I can't flash anything because it won't connect to my computer

Fixed
In case anyone was wondering (I doubt it) I finally got around to fixing this:
After searching around the internet, I noticed a lot of people's touchscreen would stop working after buying a replacement daughterboard (the usb port is soldered on this). I decided to switch out the motherboard and the daughterboard from my old nexus. Plus, my old nexus was 32gb, and the new one is 16gb, so more storage (yay).
The actual process of performing surgery on the nexuses (nexii?) was really easy, you just have to be careful to not crack the back cover, but if you do, oh well.
Put it all back together and... it works! Flashed the marshmallow factory image (MRA58K) and it feels brand new.
So there ya go. bye

USB-C port is charging only (no adb, fastboot, file transfer, USB accessories)

I recently bought this phone used off a fella. During the deal there was no mention of whether or not the phone would connect normally to a PC. I plugged it into the charger, it started charging, not IMEI blacklisted, thought "hey, yay!".
I went home with a real excited grin on my face, ready to crack this baby open by unlocking the bootloader, rooting it, installing custom recovery, ROMs, the whole nine-yards. I plug it in to my extremely-reliable, many-a-fastboot'd-devices desktop computer, and nothing. No chime, no popup, no device manager caution triangle (where's the driver?) message, nothing. So I was like "okay, bad cord, NEXT"...... I went through five different cords, 7 different ports (including a dedicated USB2.0 port off the motherboard itself and a USB3.0 hub, just for giggles). I used a Linux laptop, thinking it was a "Windows Issue", nope. Tried my girlfriends desktop, nope. I said "let's try random accessories". Went through a bunch of USB drives with different adapters, a bunch of USB-C headphones, tried connecting to a bunch of other USB-C phones I have. NOTHING!
So, I spent the last two days as a Googling madman. I searched high and low and never found anything about anything that could help my issue. The port is perfectly spotless (one of the things I always look at before buying ANY phone), and the connections are naturally looking copper-like with no pins missing. I tried safe mode, factory reset galore, (recovery and rescue are useless)... even thought about adb over WiFi, but you need a physical connection before making that work. I tried letting the phone die (and when I say die, I mean le ded) and recharging it to 100, in hopes that defuggled it, iunno, somehow... nothing.
Here I am, at the mercy of you folk here. I'm sure some of you have enough experience to bury me - so please, give me anything, anything at all, as insignificant as it seems, it may help.
Currently, my next idea is to opt-in to the Android 11 beta to see if that miraculously fixes it. (good luck, amirite?)
EDIT 01: Android 11 did not change anything from bootloader to OS in terms of USB connectivity. Only change is the addition of WiFi ADB. (yay...right?)

Bump. I'd like to add some additional research below:
Tonight I had the January 5th update pop up on my device. I checked the baseband version on Google and turns out my device is previously a Verizon variant that must have been unlocked. It works with my Canadian Koodo SIM without any issues.
I also noticed that when I boot into recovery and factory reset, that I get a line in the log that says "Wiping Titan M", and when I look into what that is, it's seems to be Google's way of adding a level of hardware fingerprinting through public security keys. That's cool stuff, but what does it mean for me?
An additional point I must add: for some reason, the phone will drain it's battery while it's turned off. When I charge it (while it's off) from 0 to 100 with a USB charge monitor, it added 3708 mAh. The capacity is only 3430 mAh, so what the hell? I figure there must be something physically wrong with the USB port itself (is there a short that's causing enough resistance to act as a drain?) or the phone is not actually powered off and somehow some part of it is using power... and I don't know how likely that is.
With all of this in mind, I see on many other posts on the internet about people who had their USB-C ports replaced and it fixes nothing. So I'm very hesitant to spend money to get that replaced.
