[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?

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 wont disconnect.

Hi I just got a e4gt used from a coworker for 80 bucks. But I'm having issues with it. Even off the cord, it says mtp connection. Every time I turn off the phone it sometimes starts right back up again on its own, and sometimes shows that it is charging, again while it is off the cord. Anyone have this problem? Since I got it used can I still take it to a sprint store and have them fix it? Thanks.
Its really annoying. I want to root it before I switch my service over since I want wifi tethering.

I have had this problem before. Once with my launch day e4gt and twice my current e4gt. The first one, I took to a corporate store and they replaced. The two times with this phone, I took a wooden tooth pick and cleaned the USB port (with the battery out). So far for me, that had remedied the problem.

Use another USB cable

I tried a different cable, same thing. Even when I connect a cable to the phone but not the computer, it thinks its connected. Starting to think I have a bad USB port or something. Since its used, do I have a manufacturers watlrranty or something?

If you have TEP, it would be free replacement at a sprint store. If you don't, it would be $35. We don't care about devices be used, per say.
However, this is all assuming there isn't corrosion in the charging port, which will generally cause the issues you are having. Take a peek in there with a small light and see if you can see any white cloudiness or rust.
Sent from my SPH-D710 using xda premium

What is TEP? Does the warranty carry over of im not the one who originally bought the device? The guy bought it in september i think.
Sent from my SPH-D710 using XDA

It sounds like liquid damage to me.
Look really closely inside your charging port for anything green/white, especially toward the very base of the pins. Also, look at the charger itself for any green/corrosion on the pins. If you find any, dip a toothbrush in some denatured alcohol and scrub your charging port.
Works like a charm.

Ok so after cleaning out the charger it seems to charge better, but it has a different problem too. It doesnt stay off. Every time i try to power down it automatically turns itself back on. I want to root this phone before i switch my service over. Is it safe to root this phone if it doesnt turn off and stay off? And would a coroded charger port be the cause of it turning itself back on?

Make sure the device is usable first. A corroded charging port could definitely help in bricking the device, by not completing a full flash during installation of software.

hi all,
n00b here so go easy !
im having similar issues to the OP, with the phone constantly telling me that charging has been paused , voltage too high , even when the phone is not charging.
my phone has just been returned to me from a warranty repair for a faulty button and camera , it took almost 2 months to have it repaired by samsung.
i really cant face not having my phone for another 2 months if it needs to go for repair again.
how much would it cost to have the usb replaced on the phone if i was to bring it to a standard phone shop ??
thanks in advance guys.
p.s. i wouldnt risk trying to D.I.Y. it as im really not good at that kinda stuff.

That's very odd. I've seen liquid damage cause the phone to stay powered on constantly, but normally doesn't have anything to do with the charging port.
Pull your battery and leave it out for a few hours to fully reset the internal battery and see if that does the trick.
Did you use Denatured or Isopropyl alcohol to clean out the port? If not, you may have damaged something.. It doesn't take a whole lot of alcohol to clean out the port, just a dip into the alcohol with a toothbrush and a lot of scrubbing.
Regarding this being a widespread issue, I don't know if the port is more susceptible to liquid, but I have seen this issue four times over the last month and a half.. (Mainly with the Galaxy Nexus) Cleaning the charging port has resolved it 100% of the time for me and I have not heard back from anyone saying the issue returned.

OK so for some reason the charging works and the phone is able to shut off. Now I have a new problem. My e4gt will charge when plugged into the pc, but the pc doesn't recognize it. I want to root my device, but the computer will not recognize it no matter what! I tried uninstalling the drivers, reformatting my phone / sd card, restarting the computer, reinstalling the drivers, and i just can't get the computer to see the phone. What can I do? This is driving me insane.

Phone will not charge / freezes when plugged in

Hey guys,
I just upgraded to a Note II from a Captivate. I've had it for about month completely stock, in the last I'd say 3 days I've been having this really frustrating problem. Whenever I go to charge the phone, it will charge for only a second or two and stop. Sometimes it will go back and from charge, stop, charge stop. But also when this happens the phone freezes up. If I have low battery, every time it stops charging that window pops up stating low battery, but I can never close the window because the phone is frozen. The back and menu haptic buttons will not work as well, the only option is to use the physical home key. I have to restart it several times to get it to charge, and make sure the screen turns off since sometimes it won't.
Has anyone else had any trouble like this? Any advice would be great. Thank you!

Factory reset

This sounds like a physical defect to me, the note 1 was plagued with it. Have you tried wiggling the cord in the slot?
Now that I reread your post I would be taking that device into where you bought it and have them document the issue. Since your stock this is an easy process and having it documented at the local retailer will (according to att customer service) increase your chance of getting a new device over a refurb.

I tried a Factory Reset, I plugged the phone in right after and didn't have any problem so I thought okay maybe that did it. Went through the rest of my day without trying again. Now, trying again before bed only to find that when I plug it in now, it charges for a second, stops, then brings up the notification that the dock has been attached. I'll be taking it back to At&t tomorrow and will report my findings. Thanks for the help thus far.

Was having a similar problem with mine. Okay usually when I would charge it it would stop and then restart. Additionally, I noticed that I could not connect to any computer or USB on the go devices as it would not recognize them. In the end I went with my Samsung phone to the service center near me and they repaired a defective module for the USB port on the spot. Now it works like brand-new.

Honestly this sounds like a bad cable. A dirty in port in the phone. Or a wet connection. Try using rubbing alcohol and qtips or smaller cleaners. Give it a couple minutes to evaporate when done. If that doesn't fix it your phone has internal issues. Stock. Triangle away. Ask for a replacement. Will be fulfilled. Especially if problem is provable.

I apologize for the delayed reply. I waited for the phone to do its charging fit at home before taking it to AT&T....twice...I went to two separate stores because both are so close to me, and BOTH times the phone did not do it while charging in their store. I told them I have been using the Samsung charging cable and block, along with some other from different android phones, and all were giving the either stop / start charge with freeze, or the stop/start charge, "dock is connected," freeze. They told me it must be a bad block, and that the other chargers I am using aren't providing enough amps, hence why the phone gets crazy. I just thought to myself, you've got to be kidding me. So I went back, stopped using the block I got with the phone, I found my girlfriends usb power adapters from one of her old Apple devices (...I know right..) and used that along with the Samsung cable. So far, I haven't had a problem with it. I also tried my neighbor's charger from her S3, and that worked fine when I tried it. The phone does still do the described problem when it's plugged into other chargers, even my car charger. I might try cleaning the port itself as suggested and see if that does anything. Also was suggested by the AT&T rep to get a charger that's "high amp," so I'll give that a try as well. It just doesn't seem normal to have to go through all of that trouble though, I don't think Samsung would make their phone not be compatible with other micro usb charger devices?

[Q] Brickd hard or soft

Hey not really a noob, been flashing rooms since I had my vibrant. Flashing this morning ran into an issue. Was using Odin, said passed, disconnected my phone and its been completely unresponsive since. No charge no recovery, no download. I just think I'm doing something wrong, anyone have precise steps to check to see if it will enter download mode from this state so I can flash back to stock at least?

Feel free to move or link to a thread with the answer.

try removing your battery sim card and micro sd card for 5 min then then plug the wire back to phone while holding both volume buttons then put all your sim sd and battery back (OR JUST YOUR BATTERY IS FINE)and see if it reads it now ?

So the wire should be plugged in the wall or computer?

Still nothing. Just hoping I don't have to get rid of it

The wire should be plugged into the computer assuming you have all the Odin files you need to flash it back
Sent from my SGH-T989 using xda app-developers app

Yeah it didn't work. Still unresponsive, a jig should work no? I just need to get into download mode, flashing back is the easy part

yes a jig will most certainly work get one on here this is the one i have http://www.amazon.com/SainSonic-Don...id=1365710755&sr=8-1&keywords=samsung+usb+jig works like a charm takes 2/3 days and your good to go hit the thanks if i helped

If the phone is completely dead after unplugging in the middle of odin then the phone will most likely not boot up even after using a jig...the reason i say this is because the same thing happened to me and i tried the jig but nothing your best bet might be to claim the warranty if you still have it (usually lasts for 1 year or more if you have their plan) and act stupid when you go to tmobile...
