Hi all, I had rooted my wife's phone months ago and off and on she started having usb problems... I finally got fed up with messing with it. (Computer would not recognize it off and on, would not charge when plugged in intermittently, would think it was plugged in when it wasn't)..the biggest thing was it would randomly go into dock mode..
So I went back to sfhubs rooted stock el29.. decided the best bet was to accept the ota to make sure it wasn't a software issue. Now her phone is in a limbo of no root access but still has Su and mobile Odin as system apps but i can not gain su access and they can't be UN installed I would like to either regain root or get back to stock the phone is under warranty and the bad usb is a known issue that doesn't rear it's ugly head until the ics update. Is there any way to fix this since I can't connect it to a computer?
Also it will not boot into Odin mode just does a regular reboot. I can get into stock recovery though..
Thanks for any help.

Bad USB connector
Many people have experienced this problem. It seems to be related to a dirty or corroded USB connector. Symptoms could include:
- loss of USB connection,
- "Charging paused, Voltage too high" alert,
- charging led on, even when disconnected.
- battery does not fully charge, although it indicates 100% charge,
- phone won't boot unless connected to power (charger/PC),
- Car mode activates on its own
Took my Epic Touch 4G to Sprint Store for repairs under Asurion warranty. Upon disassembly and inspection, they found traces of corrosion in the USB connector, and marked its as water damaged, even though the moisture sensor labels were Ok, This unit has never been immersed or close to a wet environment. My best guess is that the corrosion could have been caused by condensation on a poorly constructed connector.
The bottom line is that to get it replaced under warranty, I will have to pay the $100 deductible to Asurion for a refurbished unit.
To try to fix it yourself, google android central Epic 4G Touch corrosion charging port post for some suggestions (sorry, cannot post link).I did try most but was not able to get rid of the problem, but some people have.
If you still have problems and feel like attempting the repair yourself, you can purchase the USB Power Connector Board for approx $ 27 at cellphone-repair-shop dot com and search for touch-4g-micro-sd-pcb-reader-assembly-and-flex-cable (sorry again, cannot post link)
The third option would be to fork over $ 100 to Asurion,
Good luck
What about this? Power off the phone and remove the battery. Hold the power button down for a few seconds. Get some rubbing alcohol and a toothbrush with soft bristles. Pour some alcohol onto the toothbrush then give it a light shake so it's not dripping wet. Lightly brush the inside of the USB port at all angles. Don't be really rough with it. After you're done, closely blow into the port with some effort. After that, let the phone air dry for an hour before replacing the battery and powering up. Rubbing alcohol evaporates quickly but an hour is playing it safe. Don't pour it into the phone, just get the brush wet but not dripping wet.
I had the same problem...use >>> DeoxIT D100 <<< it fixed my usb port issues for good.

I was installing a full body shield on my phone today ( the kind where you have to wet the phone) and I think maybe I got some water into the phone, probably the charging port.
I left the battery out of the device for about an hour and put it back in and every thing was good. But then I connected it to the comp via usb and the comp recognized it, then didnt recognize it, endless cycle. I thought woah. Took out the battery, blow dried the charging port, left the battery out for a while. I connected again back to the computer and it seems fine.
Now I try to charge it.. weird stuff happening. I connect and let it charge for a while its fine.. then I disconnect and it still thinks its charging. After playing with the phone for a bit in battery settings it realizes its not charging fine. After a while I connect it to the charger, shows not charging, after a while shows charging via USB. Now again its not reconizing the charger.
I'm scared as **** and just took out the battery.. what do I do?

Have you tried the rice trick?
Sent from my SAMSUNG-SGH-I727 using Tapatalk
some people say put battery in rice for 48 hrs to take away all water. Plus there is like a small litmus paper on battery, it usually is pink w stripes and changes color when it comes in contact w water. If the color hasnt changed you can still get the phone exchanged, but try the rice trick.
this phone doesnt have the liquid stickers.
here's the thing, it was such small amounts of water being used I don;t think rice would work. Like rice just waits for the water to come out and dries it so the phone is fine before you use it.
I'm pretty sure the water is already out, I'm stuck with a problem.
Can I Flash to stock, lock the bootloader and send for warranty.. or will they know there was water involved?
The (insert charger) popup keeps coming up as well. Repeatedly
Odds are, you ruined it the minute you put the battery back in and turned it on. You can try taking the battery out and putting it in rice, but odds are that the damage has already been done.
I'm pretty sure that all of the instructions for the wet application protectors tell you to leave the battery out for at least 12 hrs, preferably a full day, before putting it back in and turning it on, and that is pretty much the reason why. If water gets anywhere it's not supposed to be, it can cause damage to the components. Live and learn I guess.

This phone has 4 liquid stickers. I just found all of them. They all work.
One ON the battery, one above the battery by the gold power contacts and two under the plastic cover.

I just updated my post above because I realized it could be helpful ^
Good luck to you as well!
...and now it's being laggy. I'm guessing this is due to the device always seeing anf not seeing a usb input.
I;m going to replace the charging jack tmrw from a technician I know.. hopefully that would fix the problem.
I gave it to one of my tech's. He's gonna open it up and try to clean any water damage and see if the stickers are good.
I have 3 ways to proceed:
Send it to my carrier, they'll give me a new/refurb phone. Cons: 35$ fee, may get a refurb phone, need to unroot phone, if water damage found, im stuck with a bill for a new phone.
Send it to Samsung, they'll repair it. Cons: I'll have no phone for a while it takes them a week or two to repair it. Need to unroot. If water damage found, they'll send it back unrepaired.
Get my tech to repair it by changing the chargin jack flex cable. Cons: Gotta pay him a fee probably $50-60. If something else goes wrong with the water damage later on, I'm screwed.
Not sure what to do right now.
Phone recently keeps saying it's charging even though it's not plugged into anything. When the phone enters the charging state the LCD turns on.
This intermittent problem, when bad can keep the LCD screen on for hours.
Anyone else experiencing this?

I tried doing a factory reset, I'm running stock ROM and haven't even unlocked the boot loader.
Sounds like maybe it's a hardware problem. To make sure, flash a stock rom using the GNex Toolkit and see if it improves. If not, re-lock the bootloader and send it in for warrantee.
Any other ideas?
i had this happen to a focus s. no matter what i did, i couldn't get rid of it. i think it's a short in the usb slot on the device. i had to rma my focus s and replace it.
Sounds like a damaged or dirty USB connector. Had this happen on a couple of phones. Clean the phone's USB input connector with either compressed air and or a soft tooth brush dabbed (not soaked) with some electrical contact cleaner or 99% alcohol and let it dry. Power off and remove the battery before trying either method. Is the phone water damaged or has it been in subjected to a damp area (sweaty pocket) for any length of time?
Hopefully it's just dirty and not damaged.
My phone has started doing this recently too. I haven't tried electrical cleaner, but I have attempted to blow it out with compressed air and clean it out with a pin. I can't seem to fix the issue, but I have found a good workaround...
After charging the phone (or having a USB cable attached for syncing) and removing the cable, if the the phone still thinks that it's charging, I simply power it off and remove the battery for a second. Re-insert the battery and power the phone back on... that's it... my phone will no longer be stuck in charging mode. Simply power cycling the phone doesn't work, I have to physically remove the battery for a second.
I had this issue with mine too, also when plugged in it would show charging, buy battery starts said "not charging." Sent it to Samsung for warranty repair, they claimed it was overheating and had to replace a part. Free repair though!

Hi Guys, long time lurker and flasher, first time poster.
I've had a Galaxy Nexus for a few months, and love it. Flashed a million different roms, all is generally well.
Starting a few days ago, my phone started beeping and waking up. Upon closer inspection, it's because it thinks it is being plugged in and unplugged, up to twice a second. If phone is locked in my pocket, it wakes it up and annhilates my battery D:
Do I have a faulty motherboard/charge IC/socket? I've tried a wipe/reflash of the rom I was using, as well as a few others, and the issue persists.
It's also extremely intermittent. One minute it's spamming the plug/unplug messages, then it'll be fine for a few hours, then it'll wake up randomly, then nothing again.
Anyone else had any similar issues or have I got a dead phone? It's still under warranty, so that's good.
THANKS
A similar problem with mine started yesterday. At random times, the lock screen says it is charging when it's not plugged in. Plugging it in sometimes causes it to stop displaying "charging" and unplugging it makes it say charging again. Reboots and reflashes don't help. When I get home, I'm going to switch batteries and see if that helps, otherwise i'm thinking it's a hardware problem.

I changed batteries and it worked for several hours, but then I plugged the phone into a charger and the problem came back. I cleaned out the USB port with a brush and now the problem is gone for now, but it could easily come back later. Turns out this is a common problem and there are many thing that may help, but it may just need replaced. Some things to try:
battery pull
sim card pull
use only the "official" samsung charger
let battery drain to 0% then full charge
clean usb port with brush and/or compressed air and/or denatured alcohol on a brush with phone turned off
carefully bend the tab in the usb port upward
clear dalvik/cache etc
factory reset
repair/replacement
from most of the posts that i have read about this it seems that its most likely down one of 2 things:
1: There being dirt inside the usb post - possible solution try cleaning out with a toothbrush/ cotton bud VERY CAREFULLY
2: The pins inside of the ubs socket being bent and touching, this makes the phone think that its charging. - possible solution VERY CAREFULLY try bending the pins back into the standard position, so they aren't touching.
Hope this helps.
I've noticed this is a typical Samsung issue might gf s2 does exactly the same ....

Thanks for the tips guys, I'll give them a shot and let you know. I've got a heap of air dusters at work, and some really fine gentle toothbrushes, so hopefully it'll be all good.
I really don't want to deal with warranty claims if it's a faulty phone :'(
My problem came back last night after brushing the usb port. I looked inside the port with a magnifier and it looked like a birds nest in there. I took a dental pic and spent 20 minutes digging out gunk, spraying electric contact cleaner on a brush and brushing it out, blowing it out, and repeating. That deep cleaning seems to have worked.

That worked for me too. I used a toothpick soaked in rubbing alcohol and a can of air pulled out lots of black gunk on the contacts as well as lint. I have had plenty of android devices but surely none have ever had a problem like this. Glad to find a solution thanks.
Get a replacement!
Had the same thing happen to me unfortunately I wasn't covered under warranty.
Tried every thing and it always came back!
Got a new phone (this time nothing but the stock usb charger) and no problems yet.

I want to mention this first: The, USB-connector is FINE. There is nothing wrong with it. I have cleaned it, USB fits tight and wiggling the plug does nothing. The contacts on the connector and the cable looks fine, not bent or anything. I have taken the phone apart and I checked the connector and nearby components with multimeter, it pushes 5V to the components near the connector, without the battery connected.
The problem is that when I insert the USB-cable to the phone, the battery goes to 0% and the phone shuts down. Then the phone shows an image of a battery + exclamation mark in yellow triangle. If I turn the phone on and insert the USB-cable on the GIO-screen, it will not shut down until I remove the cable or reinsert it (it depends). At that stage the USB-connection is fully working, removable drive, tethering, adb, etc. It will not charge though.
I checked the voltage on the battery connecor, it was under 2V. On my Galaxy Y and my sisters Galaxy Trend, it was around 4-5V. This could mean, that this is an hardware issue? Is there anywhere a diagram of the circuit, so I know what to check? Basically on the front side, everything I checked near the USB-connector was around 4-5V, but on the back side, it was under 2V.
The warranty has been expired about an year ago, so I cannot send it to warranty repair.
EDIT: I solved it! But I did not manage to locate the problem though. It was an hardware issue, for sure. I put the phone in oven for 5 minutes to reflow everything. Apparently there was a cracked solder joint somewhere.
Hello everyone,
I have a major issue regarding battery.
Here is a rundown of what has happened.
1. There was moisture detected at first by the sensor and there was in fact moisture there after I plugged in my usb charger in and saw water around the usb-c connector. This was due to humidity most likely as I live in NJ.
2. I cleaned it out with a cue tip at first and nothing changed. Plugged my usb charger back in to see if water was around it which it was not obviously.
3. Left my phone on overnight and then the Icon went away but, I could not charge my phone anymore despite their being no notification showing me that the phone was incapable of being charged because of "x" reason. I also made sure to use a shop vacuum to remove any other residue inside the phone.
4. Turned my phone off and then I was finally able to charge it.
5. Turned it back on and then the issue I have now is happening along with the fact, when I use my charger that came with the phone, I get a notification that I should use the charger that came with phone if I want it to charge faster....
Not only that but, to get it to charge occassionally I had to turn airplane mode on and THEN it would charge. This is spotty because it works sometimes, sometimes it doesn't.
Today I hit a breakthrough. After doing a factory reset (that literally did not change anything at all. Same problem, despite everyone at reddit suggesting a factory reset) I loaded my back up file that I created before the factory reset and *poof* the issues described above vanished.
However. When I put my phone into airplane mode and turned it off (tried to mimic the most successful variables that allowed me to use the phone without issue) and then plugged a my usb cable in, it charged no problem. Then when I turned the phone back on, the evil bleeping and screen dimmer of death came back on.
I am not up for a loaner phone and I can not wait 2 weeks for a new phone seeing as I work and people are always calling me.
Recommendations?
What do I do if no one responds?
Bump?
Not sure what else you can do. Sounds like the port got shorted out partially. I suggest grabbing a Qi charger and going that route in the interim, that should work without issue, unless the circuit on the board is the issue and not the USB port. I assume you are using a different chable/charger than the one that was wet?

Try leaving your phone all night in Rice. The rice absorbs moisture from the phones when they fall into the water.
