Big issue with USB

Hi everybody. I have had some strange issue. It is like if the usb entry wasn't working. The phone doesn't connect to the computer.
- If I plug it, it doesn't appear as connected.
- If I charge it it doesn't charge.
But here there is the thing... When the phone is completely powered off, if I connect the phone to the computer, the phone powers on, shows the bootlogo (in my case DoomKernel) and then powers off (without charging)
It is like If the USB entry was broken or something like that... I cannot flash other fw or kernel and I can charge it because I own a broken arc. I change batteries, charge, and rechange batteries.
Any help would be appreciated
Cheers

Have you got any Nandroid backups you could try restoring from when it worked?

I think it is a hardware issue. I would try that, but my nandroids are from other android version.
Currently I am using DoomKernel v22. If I restore a CM9 nandroid it would bootloop...
I have contacted with the service centre, and the warranty covers this, but I would be a month and a half without phone... I am trying to repair it myself.

That's a hardware problem. Probably with bq24185 chip. Without charger or usb cable connected, you can reboot your phone and check (via BBS) for a constant kernel wakelock called bq24185_watchdog_lock.
I don't know about Spain, but in my country, they gave me a new Arc S (they couldn't fix it) when this issue happened to me 6 months ago. Don't forget to flash stock FTF and relock bootloader (even if it doesn't restore the DRM keys) if you used official unlock method.

Yes, but I cant connect the phone to the pc
It is like if the cable entry was broken. Anything detects the phone: charger, pc...
I cannot enter fastboot or flashmode because the phone enter this modes when is CONNECTED to a pc pressing several keys. In this case, it never gets connected...

It occured the same problem with me, but in my case I was able to flash via flashmode. I can only guess that your phone have more things with problem.

I bet your using a Laptop.

I was in a hotel and only took my laptop a cable and my phone. then i had the exact same problem you are having. Turns out laptops usually only have 1 usb port inside. it hits a usb hub and then gets extended out to the ports you see on the outside of your laptop.
Laptops are all about saving battery life. so the hub takes some then after its all split up there isnt much to give your phone. so it never even recognises it. I was so mad. I thought it was the cable the whole time then i get home and the cable is fine. i went 3 days with no phone because it would not charge off the laptop.
Good luck.

The problem IS NOT in the laptop. My phone isn't recognizing ANYTHING. I plugged it to my charger but anything.. I don't know if I am explaining myself correctly.

Yes... that's why I think it is a hardware issue in the usb entrance to the phone...
EDIT: I have noticed, that when I try to get into flashmode, I unplug the phone, I press back key, I connect it and the green light appears for a milisecond, but I can't make it stand.... I can't get in any of the modes...
EDIT: The same with fastboot. I plug the phone while pressing menu key, blue light appears but suddently it goes.
EDIT3: I downloaded the rom I was using from the phone using wifi. I moved it to /sdcard. I rebooted into recovery and after wiping, I flashed it. I still cannot get in fastboot or flashmode...

[Q] Won't Turn On. Tried Everything

My phone won't turn on. I own a samsung galaxy nexus (verizon). I've had it for 16 months. I was talking on my phone then ended the call. Had it charging to the wall. Set my alarm for the morning. When I woke up my phone was off. I tried to turn it on. No luck. I did the 10 second volume down plus power button. Still nothing. I pulled the battery and did the wall charger no luck. I plugged it into my computer with the usb. It doesn't register it. The phone has no lights on it. The screen doesn't light up notifying me of it charging. The little flasher light on the bottom doesn't light up. Please help I'm out of options. I called verizon and they said i'm off warranty. I have no other options that I know of besides to get a new phone. I love my phone. I unlocked and rooted it. I have everything on it. I need to get it back on. Any and every idea will be tried. Thank you!!!!
Micah

Question: Did you use the same USB cable from the wall charger to the computer?
Could be a couple of things...if the answer is YES, I would change USB cables and see if that fixes it.
If the answer is NO, you could try to clean out the microUSB port. It's possible that some dust got into it, causing a small shunt or keeping the pins from connecting. I know my previous Galaxy Nexus had this issue...found out I had a piece of lint that somehow got into the MicroUSB port and kept the USB plug from seating correctly.

reply to tkirton
tkirton,
I used a different charger than the micro usb cable. in fact i used multiple different chargers. I also blew out my usb ports and cable. I tried again and again, using different usb ports as well. it didn't work. My computer just doesn't seem to identify the cable or phone like it use to.

If you have exhausted all possible means then the last resort for you is to try the USB jig. Usually it can wake the device up and put it to ODIN mode. If that fails too, then its a possible major hardware failure.

Question , when you connect the charger, does it light up the battery symbol ?
Have u tryed to "center "the phone usb port with a needle or something like that ??
if not plz try this :
1) turn the phone off and take the battery out
2) take a toothpick, knife , pin or whatever will fit into the micro USB slot of the galaxy nexus.
3) VERY VERY slowly make it so that the little shelf like connector is in the middle.
4) connect ur phone and hope it gets back to life

When i connect my charger i get nothing. no symbol no lights no response. and the centering of the usb charger didn't work either. my phone has such a tight fit i couldn't even fit a thumb tack pin into it.
I've done lots or research on the USB jig. I'm going to try it. or find someone that has one. wish me luck!

Good luck. USB Jig might be your last resort before you send it to repair.

[Q] a BRAND NEW kind of charging problem

Before everyone starts accusing me of not running a simple search, take it easy, been done. And yet, nothing to help me on the matter.
So here's the thing:
Her phone won't charge. Not when plugged into the wall, BUT when I plug her phone into the computer it is recognized and allows file transfer and everything, but just that - it still won't charge.
Here's what I've found out so far:
- Not a problem with the charger: I'm using the original charger, and it works flawlessly on my own Gnex running PA 4.4
- Nothing wrong with the battery: swap batteries between phones, my phone works fine with her battery, her phone still won't charge.
- When her phone is completely OFF and I plug it in to my PC, it plays the sound of connecting and disconnecting a device, and prompts that it doesn't recognize the USB device. If I tap the power button for a second while it's off (not holding it long enough for it to turn on), it does the same thing connecting-then-disconnecting sounds and "doesn't recognize the USB device".
So - has anyone ever run into this problem before? Know how to fix it? I know the chances are it's just a hardware malfunction, but it's weird because of the ability to transfer files- usually the problem is the reverse.
In the meantime we're using my phone as a charger for both batteries untill we get the spares and wall charger we ordered, but it's a real pain.
Just trying to find a better solution than taking apart the phone and try and fix it or just ordering a new Nexus 5 (which is tempting, but don't really have the money to spend on it...)

Its the micro USB port the pins are bent homie.
Some pins allow charging some allow data transfer. The ones for charging are damaged in your case.
Sorry to bring bad news.

Yup. Just this moment after a really really really close examination of the port and comparing it to my own phone, one tiny half a millimeter peice of metal is bent out of place and broken. Gotta order a new port ASAP and try and change it.
Thanks mate!
But hey, look at the bright side... a fun home project to immerse myself in instead of prepare for my finals! :laugh:

Back with worse news. Just replaced my wife's micro USB port on her i9250 GNex, and.... same thing. Still won't charge, computer recognizes it. Now I'm completely baffled. Thought for a moment that maybe I had been such a fool as to have put back in the old port, but unfortunately, it wasn't my stupidity.
Ideas, anyone?

My Note 8 won't charge, not sure if flex issues because it recognizes a otg cable

(Not a native english speaker, sorry for any bad writing) Good Afternoon, first post made in this forum and I'm very desperate to find out why my tablet is not charging, I have tryed with 2 different charges and 3 usb cables but nothing, but when i connect a OTG cable with or without a USB pendrive in it, this will be recognized so i'm not not sure what the problem may be.
It is the chargers?
The Micro USB cables?
Or the Power Source?
Plz help me. Thank you.
Edit: Forgot to add, it will occasionally after several Hours to start charging back, but if i move it just a little bit it will stop charging.

This is your problem: loose USB charging port. Search Ebay for this part, may be cheaper if from China
Be aware that a defective USB port can read data but not charging or vice versa.
http://www.ebay.com/itm/ORIG-New-US...108?pt=LH_DefaultDomain_0&hash=item5d5a6ac87c
Replace this one is easy, just need taking the back cover off, remove two screws from this USB flex FPCB. Make sure search YouTube how to open the rear cover. Open the wrong way, you'll permanent damage it. Don't ever use metal prying tool to open the case.
This one is just an example:

TYPE C PORT broken?

Hi everyone,
Two weeks ago I charged my nexus 5x in my car via an 12v car adapter, the cable was USB-A to USB C, after about 5 minutes my phone reboot automatically then stucked at "Google" logo and fail to boot into marshmellow animation. Then I tried rebooting by pressing down the power button for about 20 second, but nothing changed (Still stuck at google). Then I pressed power button and volumn key down to enter the bootload mode, and choose power off. After that I could not start my phone or get it charged (with the original cable and adapter). My phone is never unlocked or rooted.
I finally resolved the issue by opening the back cover and unplug the battery, After the battery was pluged in again it finally come back to live.
Everything works OK until recently I want to copy some videos from my PC to nexus 5x, but nothing happen when I connect the phone to my PC (It works before), I could tell the driver is correct and the USB port work well as my Nexus 7 could be recognized just like normal. the USB configuration is MTP in developer options, but there just nothing change in device manager when the nexus 5x is connected. I've tried different PCs and other cables, the situation is the same.
Now I am suspecting the type C port is no longer able to transfer data but charging. I am planing to visit the nearest apple store and try if the original type C cable could work (I don't have any other PCs with typec port available).
Will update....

You took your phone apart? Wtf. Pretty sure you voided your warranty with that..

Actually I did not expect any warranty as I am using the phone in China, but nexus is never officially sold here.

I had my 5x turn off on me in the middle of the night while charging and refuse to turn on the next morning.
I had it unlocked, rooted running pure nexus ROM and had the surround sound and EIS mod though.
I tried other cables that I knew worked in the past too.
Maybe I had the same problem?
The phone was completely "dead" there was no red led indicator when holding the power button.
But software could be an issue I guess. I was running all of those mods for about 2 weeks however. No major drops or water damage.

Sounds quite similar!
So how is your phone now? Are you able to connect to PC as MTP?
Maybe I should try a factory reset first? But if the reset does not solve the problem it will be painful to transfer the data back from PC.

OP, does the cable you were using in the car have the proper 56k resistor? It might have partially killed your charging port if it doesn't and there happened to be a current spike.

I never got the phone to work, I got Google to RMA the phone, just sent back the old one, I'm hoping they cover it under warranty. I was using the charger that came with the phone too.

I'm wondering if you meant 12 W, not Volt. Either way, I think I"m in the same boat. Been using an approved USBC-A cable with a 12w charger in the car, and now I've noticed that the USB debugging options will randomly show up in the notification shade when the phone is NOT plugged in. The only way to dismiss the notification is to plug the phone in. Additionally, the OEM charger no longer says "charging rapidly". I'm thinking the USB C port has taken a hit.
Any thoughts?
