When i connect my G2 phone to the computer it use to have a notification to tell me it was connected to a computer and let me turn on usb storage mode. When i plug it in to my computer it does nothing just sits there charging like it was plugged in to a wall charger no option to go to usb drive mode. I am using CryogenMod 6.1.1 any ideas?
I tried 2 different cables and computers...
You might not have the proper drivers installed on your computer.

I don't think its a driver issue because it comes up as a removable disk no matter what computer i am on. It seems like it's on the phones side there is no notification like there used to be. This all started today. was working perfectly before. I have not clue what could of done this I haven't made any drastic changes on my phone or anything.
I don't know what happen i restored it back to another restore point i had it started working again! i don't know how or what happen.

You've probably got usb debugging enabled. Disconnect your phone from the computer, disable usb debugging and then connect it again.

The phone was always on debugging mode, and I still always got the USB connected notification. I think it was an Ap I downloaded that messed with the startup programs. I am not completely sure it is that but was the only major change in my phone since this started happening. So IDK glad its resolved through the restore and backup.
I've scoured the forum to an answer to my problem but I've not yet found any so hopefully you guys can help.
Somehow I managed to soft-brick my Epic 4g, just been having all sorts of problems. Anyway I'm able to get in download mode just fine so I should be able to restore my phone no problem right? Wrong.
The problem I'm having is that my computer won't freaking recognize my phone when it's plugged in. Here's what I'm doing:
1) Start Odin, have phone ready in Download Mode
2) Load up the PDA file
3) Plug USB cord in to Phone
Once I plug the cord in to the phone my computer says that it does not recognize the device (or that it's malfunctioned or some such thing).
I've tried everything to fix this! Here's a weird bit of success though:
This morning I turned on my phone, did the 3-button combo to get to clockwork recovery then plugged my phone in. The phone was recognized!! I rebooted, went to download mode and Odin recognized it! At this point I tried flashing my stock kernel and it failed. Now I'm no longer able to get in to recovery using the 3 button combo and my computer no longer recognizes my USB connection again in download mode.
Am I totally screwed here? What's up with the USB??
OH! Just wanted to add: I'm using Windows 7 x64 and I do have the correct USB drivers installed.
hmmm
Have u tried redownloading the samsung drivers? They really ***** out sometimes...
I have. I've actually gone through and tried the x86 and x64 drivers listed on the forums as well as the official samsung drivers.
Usually when Windows says the device is unrecognized or has malfunctioned it has to do with the USB port you're using not having enough power. The stock Epic USB cable also sucks because its long and skinny which leads to more power drop. Try using a better quality USB cable (I always use a blackberry cable when flashing) and connect it to a USB port on the back panel of the computer that comes directly off of the motherboard.
Some USB ports may work better than others - for instance on my Dell E series laptops I can't flash when using the USB ports on the left side of the machine, but the ones on the right work perfectly. The left side ones just don't deliver as much juice and this phone is a power hungry little guy.
Alright I got it working. I do think it had something to do with the cable. I kept swtiching back and forth between Samsungs and my old Motorola one. After a few reboots and reinstalls of drivers the Motorola one finally worked
I have had that same thing happen, tried an old moment cable and problem solved. After that went on ebay and bought some extras just to have on hand just in case. Also thanks about the usb port explanation, makes sense.

Long story short, I get the phone-!-computer icon when I power-up. So I put the phone into download mode, fire up odin, and plug the phone into the computer. Except the computer doesn't make the new hardware detected sound, and odin doesn't show the phone. It also doesn't appear in the device manager under USB devices, so I can't try uninstalling and re-installing the drivers.
I've tried 3 computers (Vista 64, Vista 32, and XP Pro), all the USB ports on each computer, and 4 different USB cables (only one was stock Samsung). I've tried leaving the battery out overnight, going into d/l mode without the battery in, holding down the power button without the battery for 1 minute. None of that would get the phone to show up.
If it makes a difference, right before this happened, I was attempting to flash back to stock with Odin because I just flashed a new rom with CWM and it was acting weird. The first time I put it into d/l mode and ran Odin, it detected fine and began flashing, but odin froze and the phone turned black.
I rebooted the phone into download mode, and restarted Odin, and tried again. Then it froze again at a different point and screen turned black again, so I rebooted into download mode again, and that's when it wouldn't detect the phone anymore.
If you can get your phone into download mode then you're not bricked. It seems like you're having issues with the drivers for the phone and possible usb cable problems. The stock samsung cable causes issues. I bought a new usb cable and haven't had issues since

Well its weird that he tried 4 different cables and three computers, all different OSs and it still wont show.......
You said that you took the battery out over night...... did you hold the power button down while the battery was out to discharge the circuits?
LOL... well I looked at the port on the phone under a big magnifying lens, and saw there was a small hair stuck in there. After much effort, I was able to get it out and now the computer is at least detecting it and saying "unknown device". I'm gonna try re-installing the drivers to see if that gets it to work.

Oops i guess I missed that part about the extra cables. You can uninstall and reinstall the drivers. The drivers are what allows the computer to interact with the phone but you're wording makes it seem like you think the drivers get downloaded into the phone (which they don't).

No, I knew that. The issue was the computer wasn't detecting the phone and so it wasn't showing up in device manager at all, so I had no way to uninstall the drivers. But it turned out to be the goddamn hair, so I'm up and running again

I'm actually having this same issue, mine boots to the Samsung screen and makes the booting noises and everything but stays at the Samsung screen.
I've tried uninstalling and re-installing the USB drivers and have all the correct files for Odin but when I put it into Download mode and plug it in to the computer Odin doesn't recognize it and neither does my computer.
Well mine was definitely caused by a hair in the usb port. You might want to try using some electronics contact cleaner (available at radio shack or lowes in the US) to clean the contacts on the usb port if there's nothing visible preventing a good connection.
Hi guy's, I would just like to start off by saying that XDA is a wonderful site full of amazing information. It just so happens that the problem I'm having isn't anywhere on this website which leads me to think if I'm the only one who has this sort of situation. Basically what's going on is that I would like to root my T989, mainly to get rid of carrier bloatware, so I looked around the internet and YouTube videos and learned how to do it, the only problem is that I am failing at the first step of it which is getting it in download mode. I downloaded Odin3 v1.85, then while running Odin I held the volume up+down buttons and at the same time plugged in the USB cable, as soon as I do that the phone boots into a screen that is showing the battery being charged instead of going to the warning screen and Windows says that the device was not recognized and the USB has malfunctioned. I did install the Samsung ADB drivers for the phone, I also turned USB debugging on, and I tried three different computers all with the same results. Oh and if anyone wants to know, I am running Android 2.3.6. Can anyone please help me? I would really appreciate it if you guys could help me find a solution to this.
BTW this is my first thread on XDA

I would remove the battery 1st and let it chill for a sec. Replace the battery, and hold vol - & + and then connect your USB cable. Do this in that exact order and you should have no issues.
Also if your PC isn't recognizing your phone I'd try a different USB cable. Sometimes that works.

I had the same problem with my previous sgs2, i tried everything from uninstalling and reinstalling the drivers, used a different usb cable, tried a different laptop and nothing fixed it, if your computer wont recognize the phone after trying everything you can think of, then do what i did and get a warranty exchange, after that my new sgs2 connected perfectly

remember that **** well lol.
TO OP:
There are a couple things you can still try, but chances are slim since you did try 3 different computers. It might have been possible that the installation of the drivers (when you plug in your phone) was interrupted somehow and it left an incomplete installation. You would need to download usbdeview and remove/delete/uninstall (forgot what term was used) everything android/samsung related.
Plug in your phone when it's on in the homescreen or something.. let it sit for like 5-10 mins for it to install everything.. there is like 5 things or so. Now try to go into download mode.
If that doesn't work, make sure you're using the t989 drivers.
if that doesn't work, then install kies
Try to mix and match USB wires and USB ports on the computer.

Hopefully you guys can help me out. I'm suddenly having issues with my phone not being detected by my PCs when it is connected via USB.
When i plug my phone into my PC, i receive the error message: "UBS Device not Recognized One of the USB devices attached to this computer has malfunctioned, and windowes does not recognize it." from my Windows XP PC. My Windows 7 PC is unable to recognize the device plugged in.
The strange thing is that even though my phone is not being recognized by the PCs, the phone will still charge.
The phone is not in USB Debugging Mode, and I've gone ahead and flashed 2 separate Kernals on my phone, but i still am having this issue. I have tested this out with 3 USB cables, on 3 separate computers (Work (win xp), Home (win7), and friends(win7)).
2 Days ago the USB worked fine for me as i was able to flash Franco Kernal and JB onto my Gnex, but suddenly it's not being recognized by my computer anymore.
Stumped.....Hoping that this isn't a hardware issue and something that i can fix without having any downtime away from my phone.
Any thoughts?
Try other USB port and other USB cable.
Sounds like you're missing some drivers... Remove the device completely in Device Manager & plug it again. For MTP, Windows 7 should find the drivers online by itself. If you need fastboot access, you'll have to download the seperate drivers for that. I'd recommend the GNex Toolkit in that case since it comes with the drivers included (you'll still need to install them of course )

Thx for the reply,
Yes, I have been using the GNEX tool kit, though not the 7.3 version that was released today. The 7.2 version was being used at home and on my work PC. I usually install the drivers from the toolkit then plug my phone in when done. The drivers have been recognizing my phone but not since 2 days go.
I'm currently trying to find the MTP checkbox in the phone Settings to double check if it's checked, but im having problems locating it.

Ah yes, that is where it was hiding....But unfortunately the checkbox is checked.
This seems like a hardware issue, but I'm not certain since the phone still recharges when plugged in

Could be... Charging doesn't necessary have anything to do with data transfer AFAIK... Do you see something in the Device Manager when you plug it? You might have to right click & do a re-scan to force detection.

Device Managers shows "Samsung Galaxy Nexus ADB Interface". The drivers look to be installed.
Also another odd thing, is that after i charge my phone and unplug it from my PC, it will continue to show that it is charging on the lock screen and in the top right corner of my phone. However if i go into Settings ---> about phone. It shows Battery Status : Not Charging.

You get that when the phone is running normally? I think for me that one only shows up when I put it in bootloader mode. In MTP mode it's just a media device like any other AFAIK... I'll check tomorrow when I'm back on my Windows laptop to be sure . Have you tried putting it in PTP mode? If so do you see the device as a camera or is it the same issue?

Google galaxy nexus nfc battery. either the battery or the port is shot. People having issues.
And get your drivers from Samsung and Android sdk. Qbking77 has a YouTube video on how to set it up.

Basically the way the Nexus One talked to other systems through USB is completely different from the way the Galaxy Nexus does. The GN uses a new protocol called MTP. Your car stereo probably can't read the files on your phone because it doesn't have MTP support.
Phantom Charging Issue
So I've gone ahead and Fiddled around with my phone for the past day trying to fix my USB issue, and I've discovered that this issue may not be due to USB issues.
Throughout the day when i was playing around and trying to fix my USB recognizing issue, it miraculously started working again. Now I am able to connect to my PCs and transfer the desired files.
Upon this issue being resolved, i noticed that periodically the screen would turn on, on it's own while being off in the locked state. I observed this issue to see what may be causing this, and it is turning on due to my phone thinking that i plugged my micro USB cable in to charge it. The charging indicator on the batter flips on, and even the USB Debugger / MTP Notification is present in the notification drawer.
Apparently this is a known issue with the Battery or charging port with Gnex's. (See below the 2 youtube clips for more details for problem/fix.)

I believe my warranty is void since this phone was purchased in a different country and has had the bootload locked/unlocked a million times. Anyone else have this problem that they have been able to fix manually? Or am I going to have to cross my fingers, ship my phone to get it fixed, and hope the post man doesn't f**k up?
