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.
So when i try to connect my galaxy to the computer nothing happens. i plug it in and it will start to charge but the phone will not have recognized the fact that it is connected to the computer and the computer doesnt even say "unrecognized device" how do i get the phone and omputer to recognize each other?
Did you install drivers for the phone? What operating system are you on?
yes i have. ive tried both osx and windows 7 and i have made sure to download teh drivers for each
Have you tried to connect it in usb debugging mode? (goto settings, applications, devlopment, check debugging mode?
(I dont know of it will help, but it would be the next thing I would try)
And try different usb ports. I have heard before that it can help.
yeah ive tried all of that it and still nothing, the switching usb ports too
Did you restart the computer after you installed drivers?
I would try installing Samsung Kies (from samsung website, GS2 support page). It also installs drivers and fixed a problem I had with connection.
If all these don't work, I don't know what to tell you. Sorry. I am sure someone here with more experience will be able to help.
yeah haha ive done all of these unfortunately and still nothing, thank you for you suggestions though
Kies had an update within the hour of New years (Pacific).
I discovered this morning that USB debugging mode MUST BE OFF for Kies to recognize and connect to the phone. I'm currently backing up my device in this mode right now.
"Kies Air" also works well, without having to worry about any USB issues.
"Droid Explorer" connects fine with debugging turned on. I have to wait until backup is complete to see if it works with debugging turned off.
I'm having USB port issues right now, so your mileage may vary.
Hope this helps.
So the ota screwed up my phone. I was able to connect and intstall the stock eoh3 for xda the phone now starts up but I am unable to connect USB to root or flash any new rooms with Odin I can only connect Odin if the phone is booted up and debug and mock locations are on. If I pull the battery and put it in download mode it will not connect to the pc it just shows as an unknown device. I have reloaded drivers ect but not getting anywhere. Any ideas?
Try another cable if you have one, and try putting the drivers on another PC. For reasons I still haven't figured out, my home desktop PC quit connecting a couple of ROM's ago, and it won't even let me reinstall the drivers. I have a laptop that works fine (so I haven't gone into major troubleshooting) and my work PC also connects fine.
If the same issue repeats on other PC's and cables, there may be something wrong with your mini USB port. I had to have mine replaced a few months back.
Hi guys, was having a few problems with my phone and decided that I'd flash the stock ROM again.
Went into ODIN as you do, and as I was flashing the stock ROM, for some reason or another I heard the disconnect/reconnect noise that Windows makes when you remove a device then FAIL came up in ODIN.
Now my phone's stuck with a phone connecting to a computer on the charge screen, it can't go into recovery mode but it can go into download mode.
Tried connecting it to my PC in download mode, and even though I've got the Samsung USB Drivers installed I get the 'USB Device Not Recognized' message, which means I can't flash the stock ROM in ODIN anymore.
Does anyone have any advice? Thank you.

I have it installed, and I installed the USB drivers from the soft bricked sticky in this section. Neither have helped.
Hi!
Hi, you guys install ADB on your system? And also USB debugging mode on the phone?
Should be turned on which can be done by going to Settings>Applications>Development and select USB debugging.
Try this, for me its works

I can't even turn the phone on at the moment. Only thing I can do is go into Download mode.

Try this, take out the battery, then press and hold the ON button for 7-10 seconds (the longer the better). Reinsert the battery, then press ON button to start it. This is a soft reset, and wipes the temporary memory and empties all remaining power in the circuits. This helps on many phones and even laptops that won't start properly or show anything on screen.
If this does not work, try the next step. Again, do as above. But after inserting the battery, do not turn the phone on, but press and hold the ON button and the HOME button at the same time for 7-10 seconds. This is a hard reset, and works best if done after a soft reset. Just be sure the battery has at least some juice in it and isn't empty. If possible, try with another battery if this does not work.
Hope this helps!
Try going to device manager, you will probably find your device as an unrecognized device, uninstall the drivers, unplug and then plug it again and see.
if the prblm is hard then do a fresh installation of kies,device etec etc.....but if u have ur device in the device list on pc then first uninstall it...if possible try recovery mode and reset...
I tried everything you guys have suggested and none of that worked. Anyone else got any ideas?
Try everything (and I mean everything) on the following list. Given the problems you've had & that you've already tried some of these things, I'd try another PC. And if it doesn't work first go on another PC, then go thru the list & try everything on the 2nd PC.
*Ensure Kies & it's processes aren't running in Windoze task manager. Kill them if they are.
*Try different USB ports; you must be using a 'powered' or mainboard port.
*Try different USB cables (particularly the cable that came with the phone if you're not using it now)
*Try different versions of Odin (search on here/Google)
*Uninstall Kies, reboot, redownload & reinstall it, reboot, try the flash again. Also run Windoze Update.
*And if all this fails, try a different PC.
Tried all the above and a different PC.
It didn't work. I could fix the phone if the computer would pick up that the phone's connected - it just doesn't.
Total Removal of KIES including registry entries .
Reboot PC install a new copy of Kies .
Phone backup data and factory reset .
Set phone to USB storage mode using the Samsung cable connect to PC and wait for Windows to find USB drivers .Remove cable reboot phone .
Start Kies connect with cable wait for Kies to find the phone .
Note USB Debugging OFF and cable connects to a direct motherboard port only .
Nothing then only further suggestion would be to Format the PC and start over with a clean Windows install .

I can't turn the phone on, it's stuck on the phone, triangle, PC screen.
I've tried fresh installs on three different PC's.

That's a forced download mode.
Try a blind flash to a stock firmware from Odin while connected to your computer with the phone on this screen. Even if Odin doesn't seem to register that it's connected. I've heard of at least one person this worked for.
At this point, you really have nothing to lose by trying this.
Bit of an update, I plugged it in again and it installed some drivers and ODIN picked it up. Only for it to disconnect a few moments later, now it keeps disconnecting and reconnecting over and over but ODIN's not picking it up.

I know you said you tried a different cable, but that sounds suspiciously like a bad cable.
It's not the cable, thanks any way.
Update 2: I managed to get it to connect long enough to flash the stock Kernel. Still didn't reboot. Then I connected it again and flashed the stock ROM, which bricked it again. Then I flashed the stock kernel and it works!
However, there is a problem:
When the phone gets turned off, it constantly shows the charging battery icon with warning triangle and a thermostat next to it. I can't turn the phone on because of this unless I go into Recovery mode and reboot system.
Any ideas? Thanks.

Now this sounds like a faulty/dirty/bad usb port.

This was my original thought and my reasoning for flashing a stock ROM in the first place!

I in no way recommend this, and not sure I would do it if I ever started having this issue...
BUT - I have heard that some people faced with this condition have fixed it by physically moving the small wafer board inside the USB port with a precision screwdriver (gently!) to a more "centered" position.
If that doesn't work, look at replacing that part. Either via warranty service if you still have it, or a service center.
I thought I would share this. I am kind of answering my own question but I am not really sure how I got into the state that I did.
Today I realized that I could no longer connect via USB to my PC. My phone has DietICS ROM. I tried the following:
New Cable
New USB port
Cache wipe
Dalvik wipe
Factory Reset
Rolling back to a previous nandroid that I knew worked
Reinstalling USB drivers
I still couldn't connect the phone as a media device and nothing was reported in Device Manager.
I ended up trying to put the phone in download mode and firing up Odin (to see if it would show as connected) and whalla. It saw the phone. I shut the phone down and rebooted it again and everything was working as it should.
If anyone has any insight on this, it would be appreciated. I am still not sure if it was the PC or the phone that had the hiccup.
Did you try rebooting the PC? I don't see that on your list.
Occasionally I have issues with Windows 7 (and 8) where it doesn't see that a USB device was unplugged, and if I try to use that same USB port for something else it just never detects anything.
It's rare in my case, but maybe something similar happened on your end and just having a different device ID show up (download mode shows up as a different device) kicked Windows in the pants and got your USB drivers working properly again?

bah, yes. Rebooting the PC was one of the first things. I missed that on my list.
Weird... happened again.
1.) connected device to USB. Got the double beep and charging but no "MTP" connection message on phone and nothing detected in windows.
2.) Booted phone into download mode. Connected phone and windows saw it.
3.) Rebooted phone again and everything works fine
Happened again (updating this thread for no apparent reason).
Fully powering down the phone and then booting it back up (cold boot) seems to be fixing it.

Ok, I download all roms and mods directly from phone browser so don't usually have it plugged into computer but have been having issue when trying to charge it with the factory plug. If phone is hot i have to reboot or it says "not charging" in stats. Might not even be related but i found out the battery also has an nfc inside it. Maybe it's something in the connection or the chip in battery between the port and battery..? Because when hooked to computer it also tries to charge right?
