2.3.4 - unlocked/rooted
Tried several PCs/Macbook. Tried several cables...
Plug the phone into USB and it charges but isn't recognised by the PC/Mac and phone does not recognise it's connected to USB.
Also, power off phone when it's connected to USB it hangs just before powerdown. Progress stops spinning and it sits hung. Unplug USB at this hung point and it powers down immediately.
Boot into recovery mode (Power/Volume up) and connect to USB - Reboot bootloader still not recognised by PC.
In recovery choose Power off whilst USB connected, again it just hangs - 'POWER OFF' highlighted in blue to confirm selection, but phone just hangs at that point unti USB disconnected, at which point it powers down immediately. It will reboot if you choose reboot option from recovery menu...
My phone won't transfer data but charges too. Except mines is a hardware issue. Dropped the phone on its USB port while plugged in. All loose now
Sent from my Nexus S 4G using xda premium
Installed cyan rom. No difference.
Phone still won't shutdown when USB plugged in. As soon as you remove USB down she goes immediately, so as I suspected it's deeper than a ROM issue.
Boot phone into standard recovery mode with USB plugged in, Choose reboot bootloader, info messages displayed
USB Control Init
USB Control Init End
Top line shows 'FASTBOOT MODE'
Still not recognised by PC/Mac.
'ADB devices' shows no devices.
'fastboot devices' shows no devices
Searching around this seems to be a 'known' issue, but the fixes I've seen documented say power down phone whilst plugged into USB, which obviously I can't do as it hangs.
PITA this as I use it as an app development phone

Whenever I plug my Vibrant in my computer makes the usb sound to let you know it's connected. However when I go to check the removable hardware, the Drive "I" that showed up when I plugged my phone in says "please insert etc..etc"
I'm trying to transfer movies and songs on the internal instead of the tiny 2gb card.
Oh yeah, and when I check on device manager, it shows Samsung SGH on there...
I'm confused, can somebody please help
Try and put the phone in download mode, both up and down volume buttons and power button, hold both until vibrant screen flashes twice then let go as soon as second vibrant screen appears. Plug USB into phone while phone is in recovery mode, it should automatically install correct drivers while in this mode.
mine did this yesterday. WOuld show connected on my phone, id click mount, but nothing happened. So I restarted phone and computer. All is well now..
Go to Settings > About Phone > USB Settings > and turn on Mass Storage.
Hi.
Last week I noticed that my I9000 running CM9 has no charging symbol on the indicator. Then I tried to shut down the phone and just charge it turned off, but it immediately booted itself to OS when I connected the cable. When I connected it to computer it just charged without charging symbol and nothing happened. Computer didn't detect it, and the phone also did not detect the computer.
Then I tried to wipe everything (data, cache, dalvik cache) and flashing a new CM10 rom (I had to transfer .zip to phone via bluetooth ) . I also cleaned the connector with alcohol and checked the leads on PCB and everything seems fine. But it still doesn't work.
This morning when I connected it to computer it recognized it and phone asked me to choose USB mass storage. But after few seconds the computer reported malfunctioning USB device. After I disconnected the cable charging symbol remained on like it's still connected. Then I rebooted the phone and again there is no charging symbol and no communication with computer. I also tried few other USB cables (another samsung, SE, nokia...)
Is there anything else I can try or should I start saving the money for a new phone?

If you connect it to your pc in download mode, does Odin recognize it?

No. Nothing happens. I also can't find it in device manager.
Sounds like it might be borked alright. Though if it's still charging then at least you won't have to rush out and by a new phone. Try removing your microsd card and formatting your internal storage, before you connect it. Long shot, but it might work :-/
I haven't connected the phone to pc in quite a while tbh, I usually just download the latest version of Cyanogenmod straight from the browser to update, and use dropbox to send any files I need from my PC. e.g. new songs, videos etc. Though obviously if I was reloading all my music/videos I'd need the usb connection to work.
Hi guys,
I have a Nexus 7 2012 which has become almost completely unresponsive.
Possible cause:
Last thing I remember is that I had it in my pocket and when I looked at it later - it was in bootloader mode. I pressed the power button and since then I have not been able to wake it up.
The device does not charge because I cannot feel the battery to be warm after a whole night of charging. I cannot turn it on no matter how long I keep the power button presses. I have tries two minutes on the clock. I cannot enter into bootloader by pressing power and volume down, even though I keep pressing them for two minutes also on the clock.
So I removed the back cover and pulled out the battery connector. Reconnected but there has been no change in condition.
The device shows the following signs of life.
When the battery plug is pulled out I connect it to my Windows 8 PC via the USB cable and I push on the Power button for about 10 seconds, I get in the Windows Device Manager in Other Devices a new(unrecognized) device named APX. When I pull out the USB cable the I hear the windows usb disconnect sound and the device disappears.
When I connect the battery, I connect the USB to my PC. I don't push any buttons and after 15 or so seconds I get a message USB device not recognized in the USB controllers section of the Windows Device Manager. When I press and hold the Power button (or Power and volume down buttons), after 10 sec The unrecognized device is moved to the Other Devices section and again is called APX.
I cannot turn it on. I cannon boot into bootloader. I have tried almost any approached listed here an on Google (about 10 different step by step guides) and I remain in this position.
Please help me bring it back to life. Hope it's possible. What should I try. I am fairly technical and can understand most instructions.
Had same problem,the only solution found charging via dock station.My 5 years old child broke usb port trying insert cable.
Was plugging in my G2 to charge it and suddenly it had this screen. "Firmware Update. Do not unplug the USB connection until the process is complete."
How do I exit safely? Will I corrupt any data or damage anything? I was only plugging in my phone to a wall socket, so I don't know why there would be such a screen. Help anyone? >.<
Someone knows how I can exit safely? >< Please?
That sounds like its in download mode, which you get to by turning off the phone, then plugging in a usb cable while holding vol up. I always assumed the usb cable needed to be connected to a computer for that to happen, but maybe it works if it just senses power.
Anyway, if the bar isn't going anywhere (and it shouldn't be since its not connected to anything feeding it data) then you should be okay unplugging it and turning the phone off, then back on.
Edit: Just tried it with my phone - turned off, then connected USB cable/wall charger while holding vol up and sure enough it went into download mode. I unplugged the cable, then held the power button until the phone restarted. Booted as normal.
My Lg ls740 prompted me to do a system update 3days ago and has not came back om since. It just keeps flashing from LG logo and the android man...i have tried taking battery out...factory reset...and everything above . Can anyone help?!?!
Hey guys, I'm really at a loss here. I have a Dev edition Note 4. It is rooted with a custom rom running. Randomly, the phone stopped connecting to computers via MTP to transfer files, I could not transfer any data between the phone and any computer via USB. I tried different cables and different computers. The phone still charged, but did not connect via USB. Then, the phone also stopped charging via USB, I was just getting a blinking gray battery icon when the phone was completely powered off and plugged in to the wall. I read online something about holding Volume Up, Power and Home when the gray battery icon appears and it will start charging again. This worked! However still no Data, but at least it would charge. I read something else online about holding this same combination of keys in Download/Odin mode which I tried, and this disabled charging again! WTF! Now I cannot get it to re-enable. I am at a loss here, is sending the phone back to Samsung really my only option?
I've tried: Different Cables, Different Computers, going in to USB Service Menu with *#0808# and selecting MTP and MTP+ADB, nothing works. I am positive something can affect USB settings in Download mode, but I am at my wits end trying to figure it out.
Any ideas?

Why not try wiping data/cache from recovery and install an official ROM from Samsung)either 4.4.4 or lollipop)
Bad USB port
