when I connect the USB cable onto the computer the USB notification fails to appear and the charge indicator doesnt work. The USB cable works as I had just unlocked the bootloader but now the USB does not work and I cannot charge!
Anyone ever come across this problem? RSD still detects though so I guess there may be hope
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".
My phone didnt charging with USB anymore... 3 times ago i turned off the phone em plug USB and try to charge, it started the phone normally but no charging... And now, trying any method and any USB works
My usb was bricked??? There is a way to know about it?? Ah log or a app that shows if a hardware are working??
Or any solution???
is your computer recognizing the phone when you connect it ?
if it is and charging is not working means that the charging pins of usb might be broken
I think the inner pins of a usb cable are for charging , they might be damaged .
Try using another usb cable
Sent from my GT-S5670 using xda premium
I used any other usb cable in other phones it works, but in my phone didnt USB cable neither recharger works i think it is my phone
crying!!
It all began when I was trying to transfer a file to my windows 10 Dell Laptop. I connected my phone using an original usb cable. The computer recognized the phone for a few seconds and the usb connection dialogue appeared on my phone, but then the computer said it had gotten disconnected so I had to transfer the files via Bluetooth. Since then it will only charged plugged to that computer or to a MacBook charger. It won’t recognize the original charger. It would only charge either if connected to my PCs USB port or connected to a MAcBook pro charger. I’ve tried several regular phone chargers and cables, including the original ones and they won’t work.
I thought the USB port had gotten wet because it was giving me that message when I tried plugging it to a regular Samsung charger, but when I plugged it to the Mac book charger which uses also a C Type cable it worked and the moisture detection notification disappeared.
I’ve already tried doing a soft reset and wiping out the cache...
Please advice.
It say unknown device when i plug the device in
What i tried:
- Reinstall adb and lg driver, try 3 version of lg driver (4.5, 4.1, 4.4), pretty sure i work fine because i can connect with my G7
- Try plug in another port, and i notice if i plug it to my USB Root Hub (3.0), it not get recognized, but if i plug it to a Generic USB 2.0 Hub, nothing happened, it only charging (no error appear and no device appear) - I used usbtreeview to see it
- Tried with different cable, and i bought new 2.0 cable, but it still not work
- Tried buy a 2.0 USB Hub, but it get the same error as i say above, the device just charging, nothing happen, no sound of new device plug or anything appear in device manager
- Tried change the mode of usb config to MTP, PTP , then connect each mode with usb 2.0, usb 3.0 port, same problems
your V30's usb port might be going bad.
try and see if cleaning it with a wooden toothpick helps. Don't use anything metallic or conducting

I will try it! Also do you know why it throw error at when connect to usb 3.0 port of pc but nothing happen with usb 2.0 port ? (just charging),
also when try some cord, i notice that if i use my lg g7 cable and samsung cordand charge directly, it not even charge, but if i use that cord and plug to pc, it does charge ._. , and if i use my oneplus 8 cord, it work for both charge directly and plug to pc, which is really weird since all of them is usb 2.0 cord i think
