I have this USB C to USB A cable from best buy, and when I plug into my G5 the phone freaks out. It's like I'm pluging the cable in out several times a second sort of thing, and only when I plug the cable in with the brand name facing upwards. It did work before I factory reset the phone, but it's been awile sense I've used it. I tried factory reseting again, and same issue.

Today i found out my SGS2 have problems charging the phone, not only that. i also have problems with USB file mode, and keis mode. and if the phone is turned off. i only once got it to charge without booting. else when i connect the USB it boot the OS.
What weird thing is, that ODIN works without problem every time!
The problem appeared after upgraded to Darky Rom KG6 with jkay mod. but don´t think it has anything to do with that.
I reflashed to a Stock KG6 (still same problem)
From OS restore to default, and format (still same problem)
tried to flash back to KE2 stock. an but on CWM, and clear battery stat, and system cache.
flashed backup with a KE2 Kernel (still had the same problem)
What i found out is that, when i disconnected the wall plug charger, the phone still was in a state of charging. and it don´t give the sound notify when attaching the USB. but when touch the USB cable it suddenly charge and give the sound. but it can also go in MTP mode. or start Voice recognize.
Could the be a faulty USB port on the phone, or can Battery State and kernel updates have something to do with this problem?
im now pretty sure this has something to do with the USB port. when i just spoke on the phone. it suddenly began to change between Car mode a normal.
i than tried an alternative why to deal with the problem. I tried with a hairdryer after taken out the battery, sim and sd card, and carefully heat the back of the phone.
for 5 hour there has not been any problem. both the desk dock, and wall charger is working.
got a dejavu from the xbox days and RROD.
I have the same issue. I think the USB port is faulty.
The phone reacts to different electrical resistor values on some pins of usb port that triggers car mode, desk mode, etc. So, somthing is faulty in the usb board that reports to the system that has something connected to it: charger, car dock, desk dock, usb jig, etc.
I can't find any solution on the forum, I tried with several roms and got nothing.
So... I'm waiting for a USB Jig to reset counter, back to stock rom and send it back to store for warranty
My problem seems to be fixed by using the hairdryer on the usb port. I think the problem appear from the why you hold the phone and if your hånd become sweaty. Because there are nothing to protection the usb port like the sgs1.

Did you really fixed just cleaning?
Yes it happening two times and it fixed it both times. So there is a pattern
hey guys... I posted something that worked for me...
see my post in the other thread here:

I hope this could work for you too
Last month I bought an LG Optimus Hub and I have several problems. The first is that the USB port doesn't seem to work. When I plug in the USB cable (any cable) it starts charging but when I remove it, the phone thinks the cable is still plugged and charging all the time. It's the same with the data cable and any charge cable (sans data pins). The phone also would not recognize the data cable plugged, nor does the PC. I know the port does not work but this might still a sw problem. Is there a way to root the phone via WiFi or Bluetooth? If I can do that, I won't mind if the USB port does not work. Else I'll take it to tech repair -and I'm scared of those guys as hell! They don't know anything and keep sending back the same phone with the same problem saying it's either "repaired" or "mobo changed".
Having a strange problem with my phone atm.
The other day I tried connecting to my PC (Win 7) to try and root my phone, only to find that my computer wouldn't recognize the phone. I've had this problem once before with my old Droid X, and that was due to me accidentally reversing the power lines on a homemade USB Host cable, which ultimately fried the USB port.
I thought maybe something similar had happened, as i've been using another homemade Host cable for charging the phone lately. This cable had never given me problems in the past, but I thought maybe something came lose and shorted. However, using that same cable, I can connect a mouse or a keyboard to my phone no problem, so I know that the USB port is still working. Because of this, i'm under the impression that the phone is maybe stuck in host mode?
I thought it might be the cable I was using, but I just bought a fresh one and it's doing the same thing: I'll hear the Win 7 device connected tone go off twice, but it won't show up with the rest of my drives, and the USB connection icon won't show up in the status bar on the phone, although the phone charges fine.
Tried factory reset, didn't help.
Also tried it on two different computers, and no dice. All the computers have the Motorola Device Manager installed.
Any ideas?
EDIT: ****! Wrong section
EDIT: Dunno if this is "progress", but after cleaning the port out with rubbing alcohol, and reinstalling the motorolla device manager, I now get a "USB device not recognized" error every time I plug the thing in... Mouse still works fine though.
Fixed it, for anybody who actually is reading this.
First, since my phone worked fine as a USB host, I tried taking one of my cables and grounding pin 4 to turn it into a Host cable.
No dice. I noticed a resistor on pin 4 though, which I thought was kinda weird for something that's supposed to be floating.
Then I read up about the whole "motorola factory cable" thing. Took the same cable, undid the Host mod, and then pulled out the resistor. Voila! Problem solved.
I guess the "Universal" in "Universal Serial Bus" was just a joke, right?
I have a Samsung Galaxy S Wifi 5.0, and lately it won't charge naturally (it doesn't charge when you just plug the USB cable to the port and to the wall), but you need to charge it a certain angle (eg move it until you hear the charging sound but afterwards it won't charge when you remove it!)
I have the original Samsung adapter that came with the SGP Box, but I replaced the original USB cable with another one because of the charge-at-a-certain-angle problem. I changed my USB cable thrice now, but the problem persists.
The weird thing is, it charges perfectly on a BLACKBERRY CHARGER. Although the problem is still there when I charge it with the BB charger, it never got to the point where I had to apply so much pressure on my tablet.
I just want to know what is causing this problem and a solution. I can't always use the BB charger since my sister brings it with her to school everyday. -_-
I had the same problem with my Galaxy SI. I was forced to place a book directly under the usb cable so that the phone sloped downwards. I had different luck with different usp cables. My girlfriends usb cable -that was relatively new worked fine as it sat quite snuggly/tight. Others, new or old, that did not sit as tight did not work.
Take you phone to a PC hardware store and test a few.
Hopefully you will find that it is the usb cable that is worn and not the inside of the phone.
Thanks, I'll try that out!
Hi.
I left phone with charger plugged in and went shopping.
When I came back to my crib I found out that phone didn't charge at all.
I found it strange, so I plugged the other charger, but it didn't work as well.
Then I plugged the other phone into the chargers. Both worked well.
I tried to plug USB into PC and it didn't work either. I made a factory reset and tried all steps again, but still no result.
It looks like USB port died itself...everything in port looks good, nothing broken or moving inside of it.
I wouldn't mind if I could reapply my drm keys, so I could update OTA Lollipop or Install ftf. I could just charge phone by magnetic port. But now I'm stuck with nothing.
What to do?
Hello,
Tried one other USB cable ?
If not OK with other USB cable, you can try installing Flashtool and drivers for your phone, power OFF phone and connect it in fastboot mode or the other (I don't remember the name) to see if the USB are really dead. No reset needed for that and this test call the 1 level hardware of the phone.
Mine not working aswell. The port seem to be loosen and only certain angle my pc would detect it. After a month of trying to get the right angle i think it broke. Went to my local phone shop they recommend me to have sony replace the usb port. Its gonna cost me so for now im using magnetic charger. Tried open it up to see if anything i could do but the port is tight sealed so im guessing a visit to Sony service center is inevitable.
