I search all the topics, but couldn't find the same problem.
My xt910 can not recognize USB cable and couldn't connect to PC and couldn't recognize charger.
If I reboot the system, USB is working for a short time . In this short time period if I connect to PC it can stay connected forever.
Same problem is also happening at charging. when I plug the charger, nothing happens to the battery indicator. However battery percentage is increasing.
If I connect to PC in Fastboot mode, it says USB connected, no problem.
I tried the following actions but nothing is changed:
-try different cable, PC or charger.
-factory reset.
-flashing with RSD lite to 4.0.4
-OTA update from 4.0.4 to 4.1.2
-4.4.4 kitkat Liquidsmooth Rom with BMM(system 2).
I couldn't find the reason and I'm not sure whether it is SW problem or hardware problem.

Hi all... i got my V for a month and now it is not charging anymore. neither from the ac adapter nor my computer usb..and my computer couldnt detect my phone is plug to the USB port....just nothing pops out. The debugging mode status icon, and the storage icon is not shown on my phone.
basically... i tried everything i found on Google...
reboot my phone, pop out the battery, change cable[from other optimus V], changed battery, different ports on my computer, different computer, different AC adapter, different SD card, format my SD card, factory reset, and the last thing i tried is to rooted my phone and flash with a I.H.O CM7.1 ROM.
no hope at all; however, when i plugged to the usb port or the ac adapter, then i take out the battery.. the phone does power up and say required battery....
so, if anyone had this problem before and solved it.. please help me out. between, i cant return the phone anymore.. it is over a month.
forgot to mention... it is the second time this charging issue happened. the first time, it fixed itself after i plugged into the PC, windows recognized it, and installed the drivers. [well, i already installed the driver before this happened, because i was doing some coding and debugging]
this time.... windows is doing nothing, no message pop out, no new driver found.. just nothing. and my phone doesn't shows the debugging icon on the status bar even thought i ticked the debugged mode On, and connected to the usb.
sorry for my bad grammar =[
maybe see if your pc recognizes it while rebooted into recovery.
you could also try removing all the lg and Android drivers in device manager (select show hidden devices to get at them) and then plugging the phone into the pc again.
or use a Ubuntu "live cd" to check the connectability... micro$oftware is uppity, my kid's windoze computer doesn't like my v, although it used to see it fine.
I've also read that toggling debugging, disconnecting and reconnecting the cable, then toggling usb debugging again can help.
also, froyo roms are supposed to go to a charge mode when turned off but still plugged in.
Hi dears
I have some problem about charging. First of all I am using neatrom lite + jeboo v1f rebase. The problem is when I plug in my phone for charging my phone detects it few minutes later and same when I unplug the phone. Another thing is connecting the phone to computer by usb cable. Sometimes I can see my phone in my computer but sometimes my pc give error that unknown device connected.
What do u think about this? What could be the main problem for that. In my opinion my phone's plug area.

You could try and re-install the Samsung USB Drivers.
If that doesn't work then try to completely wipe KIES and the installed drivers from your computer and then re-instlling it from samsung.com.
That should work since Kies has had an update, but if it doesn't, then indeed it's the USB inserter in your phone (don't know what it's called ) which is the problem.
I have been running on Cooks I777UCMD8 rom for about 2 months now and have had multiple powering issues. Have tried all the basic trouble shooting, not sure if its the Rom causing the issues or the AJK noswap Kernel, but nothing has been tweaked, running as is. The booting issue is when connecting a USB cable while the phone is powered off, if you try to turn the phone on while the USB cable is still attached you get a POWER RESET OR UNKNOWN UPLOAD MODE error message, only way to avoid it is to remove the usb cable and hold power button then it powers up normally.
now the problem with the USB cable, and i feel these two are possibly related, my phone no longer recognizes when its attached to a computer usb hub, it charges, but dose not enter into mass storage mode, nor does the computer recognize that the phone is attached, i have tried on multiple computers with same results, and yes all drivers are downloaded on computers. Further information; Before this problem began accruing, I would get error messages after attaching the phone to a pc VIA usb cable saying ( ONE OF THE USB DEVICES ATTACHED TO THIS COMPUTER HAVE MALFUNCTIONED, AND WINDOWS DOES NOT RECOGNIZE IT ) also, after plugging in the usb cable and windows attempted to download the drivers this error also appeared ( DEVICE SOFTWARE WAS NOT SUCCESSFULLY INSTALLED, CONSULT WITH YOUR DEVICE MANUFACTURER FOR ASSISTANCE ) it later resolved itself for a short time ( couple days ) but now when i connect the phone, nothing happens... i'm hoping somebody has had similar USB problems after flashing a new rom and knows whats going on.
additional information:
- i have two Galaxy S2 phones both running cooks-i777ucmd8 rom and both phones have had the exact same issues.
- previous problems also include boot looping, and frozen lock screen upon powering up the phone. has not happen in a while.
I was having issues with the charging the phone (slow charge in AC) and connecting it to PC through original charger/data cable. So after changing the data cable (in warranty), it solved both of the problem. But now after 1-2 days, charging is okay but I can't connect the cell with PC at all. It just charges the phone but by showing the error 'device not recognized'. I tried multiple PC/laptop but in vain. Also when I connect my phone in to fastboot mode, it just flashes the device and gets disconnected. If I try to flash twrp via fastboot it shows me 'failed: too many links' error. I'm on latest OOS 3.1.2 rooted with Xposed.
So anybody can tell me what to do?
P.S. also tried changing ROMs but no help.
Hello!
I've been having this problem out of the blue with my BQ Aquaris E5 phone: it does not respond to any USB connection (either to the PC or charger) if the phone is on. If I keep the cable connected and then restart, it will charge without problems. Once the cable is removed, it won't charge if I connect it again (until next reboot). If I restart the device without cable and then connect one, it won't work either. I did a factory reset, which did not do the trick; and even flashed the device with the latest ROM, also without effect.
Any idea of what could be the problem? I have not found anyone having the same problem, and solutions such as modifying the USB profile in the developers mode or clearing the cache partition has not done the trick.
I have this problem on a Leagoo Kiicaa MIX and tried the same things before I found this post. Did you figure it out?
