A few weeks after rooting and installing CM10 on my GS3, it stopped recognizing any form of USB data connection. It still charges from both computer and wall adapter, but I cannot initiate a data transfer or recognize my device using ADB.
I have tried:
three different OEM Samsung cables (from SG3/SG4 phones)
all the ports on two different Win 7 laptops
all the ports on an Ubuntu desktop
enabling or disabling USB debugging
with different combinations each time. No "USB connection" dialog has shown up on the phone, and no "new device" dialog has shown up on any of the computers. I know that I can get ADB working with a different Android phone (HTC Inspire 4G) so I know that my main laptop has USB ports that work and the cables I've tried work as well, so I'm left to assume that the issue is with the GS3. External visual inspection does not suggest the USB port on the phone is damaged, and the phone is only a year old, so I don't believe that is the cause.
Is there a system setting that I may have modified on the GS3 that would disable all forms of USB communication?
(The end goal is to get at least ADB working so I can try and recover some deleted files from the internal memory; I haven't found a reliable method that does not require ADB so I'm trying to get that to work. I know that transferring files on or off can be accomplished with the external SD card or over Wifi but that is not what I'm looking for)
Any suggestions from anyone?
I am not sure. Could be a software issue. I would try backing up your current cm ROM and try installing a fresh touchwiz ROM to see of that works, to rule out software issues. This could also be a android 4.3 issue. Could try stickmount or a similar otg app from the market.

I don't think any OTG app like stickmount will help; I'm not trying to connect devices to my phone. I'm trying to get my computer to recognize my phone (and vice versa) in order to get ADB working.
If I can avoid flashing a RAM I'd like to, because I'm still interested in recovering those deleted files. If that is the only thing that would help, though, then I'll do it. Any other suggestions?
Install Kies and that should get the drivers for the pc in place. Odin should recognize the device when it is in the download mode. If that works, then the pc to phone connection is OK and I'd look to software instead of hardware.
Or, if you boot into your custom recovery, either CWM or TWRP, you should be able to get ADB to recognize the device and issue commands including pulling the files on Internal storage. TWRP also has a file browser built in that might be useful.
I have tried uninstalling any Samsung drivers then using the SGS3 toolkit to install the official drivers, but that didn't change anything on the PC end.
Additionally, I tried finding my device while it was in recovery using ADB and there was no connection indication either.
I currently have CWM installed, but I didn't see a mounting option like I've seen for TWRP. Can I flash TWRP without a computer?
Or try this out: Download mode>Connect via USB>Let Windows download and update all drivers until the notification in the bottom right says it's ready to use>Unplug>Battery Pull>Boot normally>connect again. Voila! It works every time when it's being wonky and its a simple way that doesn't require a bunch of downloads!
installing insecure adb might help
Rebooting into download mode does nothing.
I believe rooting and installing CM10 means I already have insecure adb?
thanks
thanks
what next?

I have installed and reinstalled the samsung windows drivers about four times.
My phone has not yet been activated and I'm not sure I'm going to attach it to service for the foreseeable future instead of possibly using it as an ipod touch with a keyboard.
I have connected the phone to my laptop one time. I feel asleep with the phone searching for drivers (the drivers had already been installed but the status bar message said it was searching anyway) and when I woke up it seemed fully connected. I was able to cwm3 root the phone but bricked it I think by putting an ext4 filesystem on without moving immediately to an ext4 rom.
I've restored it to stock and through wifi updated it over the air to ec05
Ever since then I have never been able to connect using any of the usb ports, trying two different usb cables, the oem and a generic micro-usb cable and using either windows vista or ubuntu on this computer.
Clockworkmod reports that the phone is not connected and I am not able to see the phone as a hard drive when I set it to mass transfer mode.
In download mode, odin is able to communicate with the phone reliably.
I've repeatedly tried all ##8778# settings and I've set debugging mode off and on. Device manager shows that the phone is connected to port COM7.
Is it possible that the activation program is preventing the USB connection? I would think not because the activation status has not changed since the one time it did connect, but I'm at a total loss for any explanation.
My next step is to try another computer but I don't have one handy.
Is it possible to root a phone only through odin, or to put a file onto the sd card that can root without the use of the computer?

Thanks. I'm on ec05 now, so I'm OK with that. I'd like to root either with or without resolving the usb connection issue.
Is that possible at all?

While it isn't JUST a root that you are doing, as stated by budderocks, you can flash the pre-rooted EC05 tar file through Odin, although it will require you to reinstall any apps you currently have. This will start you out with either a stock(ish) setup, with root already included (not sure about Clockwork though), or you can use the one modified for the ext4 filesystem with CWM 3.0.0.6 included which will convert it to ext4 the first time you boot into recovery.

I have been through this myself and came short of beating my head against a wall before reading that it "may" be a cable issue.
Well, after tyring everything else, (because it couldn't be something as simple as changing to a different cable, right??!!) I pulled out an old cable from my Blackberry days and BAM - my laptop searched for and loaded the needed drivers and sees my phone everytime I plug it in now. I have also used a cable from a friends phone (not a Blackberry) and my laptop still sees the phone so I'm not advocating for Blackberry cables specifically.
Bottom line is - the Samsung cable is a piece of crap. It may work for a day or a month, but it will soon (for 98% of Epic owners) become nothing more than a charging cable before long.
Try using a different cable (not a Samsung model ) and see if that works. If so, then ODIN/one-clicks become your best friend(s)!!
Hope this helps!

I'm new and I hope I'm not posting this in the wrong place or re-posting an old question, but I have been searching on this and other sites for days and haven't been able to find anything pertaining to my question, so sorry in advance If I'm not posting this correctly.
I have a rooted epic touch with rogue boot loader installed and UnNamed rom installed. I really liked the way it was running until I had some kind of malfunction happened and now the battery charge light won't shut off and the battery drains within a couple hours of standby time. the phone is only a couple months old and would like to take it to the sprint store as I'm assuming this is an obvious hardware issue. My problem is that my pc doesn't recognize my phone anymore so I can't flash back to stock and get rid of root, voiding my warranty. I have tried uninstalling and reinstalling kies and stand alone drivers multiple times with no avail. I've tried with the battery and sd card removed and have also tried on multiple pc's (2 win7 and and xp machine). every time it says the drivers weren't installed successfully and to replace the device being connected.
My question: Is there a way to revert to stock off of the internal memory of the phone? I know there are zip roms you can flash from the boot loader but I was wondering if there was a way to flash a rom from zip and install the original boot loader as well as get rid of root? Any help I can get would be extremely appreciated and again I apologize if I am wasting anyone's time by asking in the wrong place or re-asking a question.
Ok so I downloaded the Calkin's_Stock_Rooted_EK02_ROM_v1.0 and got it on my sd card via dropbox. Flashed and now have a stock rom on it which I think is a step in the right direction.
The only thing is now I have clockwork boot loader and still rooted. and still not recognizing on pc. anyone know of an unrooted zip with original boot loader?
I couldn't get my PC to recognize either of my 2 E4GT's, each due to a different reason, both issues were resolved by going through each step in sfhub's debugging checklist:
sfhub said:
This post is for the FAQ section:
Why is the install stuck waiting for device to be connected?
Your phone isn't being recognized by your PC as an Android device.
When the drivers are installed and the phone is properly recognized, you should see the following in start->run->devmgmt.msc
Code:
Android Phone
SAMSUNG Android ADB Interface
Modem
SAMSUNG Mobile USB Modem
Until you get the SAMSUNG Android ADB Interface to show up, neither ADB nor this script will work.
Here is a debugging checklist:
1) dial ##UPST# (##8778#) in the dialer and verify AP (or ALL) is checked (if CP is checked, phone won't be recognized as an Android device)
2) restart the ADB server (choose Option G to stop the server, it'll get started automatically by the script)
3) verify USB Debugging is ENABLED
4) verify USB drivers are installed (Win7-64bit see below)
5) try a different usb cable
If you are in Win7-64bit try changing the default install location for the drivers:
If you see an error like this:
Try running the CMD prompt (or e4gtauto-sfx.exe) as Administrator. Right-click on the CMD icon (or e4gtauto-sfx.exe) and select "Run As", then select Administrator.
If that doesn't work, try disabling windows firewall.

I went down that list and everything seemed to be in order but still no recognition by pc. I kept uninstalling and reinstalling the drivers and switching usb ports and it finally installed the drivers successfully long enough for odin to recognize it and to flash back to stock. As soon as it was done the machine stopped recognizing it again. Lucky break I guess. So I can now return it to sprint and deal with the hardware issue.
I would still like to find a zip file like the tar that I flashed that installs stock recovery and non rooted ek02 rom and kernel from cwm, if that's even possible.
Thanks Godswrath, for helping me out.
You could use wifi explorer to get files on to sd card and mobile Odin to flash the tar file back to stock....

They make a mobile Odin? That would have saved my like 4 hours....
My AT&T Samsung Galaxy Note II cannot be seen by my computer if I put it into Download mode?
I have installed the Samsung usb drivers several times. Even tried the latest drivers. My computer can see the phone just fine until I put it into Download Mode and connect the usb cable. Then it sees nothing!
I have a dual boot Win 7 64 bit system, and I have installed the drivers on both partitions with the same results. I've rebooted the computer and the phone many times as well, but it does not work.
Any ideas would be helpful..

simple MTP is working well?
What is MTP? Does that mean mount the phone?
I can connect the phone to my computer anytime and see it just fine. I see the internal storage and also the SD card.
MTP - Media Transfer Protocol
That standard Phone to PC mode you can select after plugging it in.
Do you have USB debugging selected in the developer options menu?
Yes debugging is on. And I can normally transfer files. I've copied tons of music and a few movies.
I've found that these phones just don't get along well with some computers, and their usb connectivity is very inconsistent between phones. I have 2 GS3's and a Note 2. One my home laptop, one of the GS3's works fine, while the other will rarely even be recognized unless I swap the plug to another port a few times. After it's recognized, it frequently stalls on file transfers, and it crashed trying to update to JB. The Note 2 always is recognized, but similarly, large file transfers fail.
All three of these phones work flawlessly when connected to my work computer, using the same cable. I had a Focus that behaved similarly, so I think it's a Samsung issue. I've never had this problem with other brands.
Use version 1.8 of SGS3 Easy UMS app from here http://forum.xda-developers.com/showthread.php?t=1711009

That thread says it only makes the SDCard available. If I am rooting, I need the internal as well, right? So, that doesn't sound like it will help for what I am doing.

I used to have an HTC Android Incredible, so it didn't call it that. But I just looked, and yes that MTP thing is on by default when I plug it into my computers.

Thanks All!

By download mode I assume you are trying to flash something in ODIN, correct ? If yes, then make sure you are using the USB the phone came with. If you are not seeing a COM reading on ODIN, try a different USB port on the PC/Laptop. I know my USB 3.0 port always gives me problems with connectivity to bootloaders and such. Attached is a pic of what the phone looks like in download mode and what ODIN should show when it recognizes the phone. Hope this helps.

I finally did get it to work on a different computer. Yes, I was trying to root using the Toolkit, and when it got to ODIN it could not see the phone when it booted into download mode.
When the Toolkit did boot it into Download mode though, it did not show that small text in the upper/left corner on the phone screen. I could only get that text when I booted manually into Download mode. I'm not sure what the difference is....
So far, I have it rooted and am going to try and flash the NOTEorious Prime ROM. It says to backup my APNs first, which I did with APN Backup & Restore app. But it cannot restore them in JB 4.1. I read somewhere to tell Titanium Backup to make APN B&R a 'System App', which I did, but that still will not restore APNs. So, now I am wondering that if I installed the NOTEorious Prime ROM, will that 'let me' restore APNs? Or since it is JB it won't still..
Thanks for the reply BTW..
May be you can use the old fashioned way. ..use a pen and paper to write the apn and details somewhere and if you lose them on the rom. ..you can enter them manually

I still find MTP a less than optimal solution, coming from HTC devices which are recognized as external drives when connected.
Guys, Please remember that MTP is only applicable when the device is switched on. This is for internal "Virtual SdCard" and external Sd Card.
Download mode opens up the other storage on the device, "mmcblk0p*" for flashing reasons with Odin.
I've been running CyanogenMod 10.2 on my rooted HTC One for a good long while now. Since the ROM worked so well, I never had the need to connect the phone to a computer via USB in quite some time. A few months ago, when I attempted to transfer some photos, I ran into a weird and frustrating road block; my phone is simply not being recognized by any computer <see here>
I have updated all drivers
I have enabled debugging in Developer Options
I have tried rebooting Fastboot in bootloader
I have tried using the toolkits
I have tried everything I think I know
The weird part is that the phone charges via USB connected to the computer.
Since it didn't effect much, I just figured it was a glitch and I never ran into a problem again--that is, until today. I hadn't used my MHL adapter with the HTC One (only my GNexus), but after reviewing an intended installation of a Pioneer Appradio, I wanted to ensure that my One would work with the MHL. Hooking up my One to the Samsung MHL adapter (and power supply of course), I get no display on my television.
I am now beginning to wonder if the USB port is damaged. Visual inspection doesn't reveal anything, but I am curious if anyone has had this problem and would appreciate any help. Is there any way to test if I've fouled up the port?

Have you tried adb with a different rom or stock via ruu? If it still dosent work then, either your usb port or your cable is messed up.

I'm currenty transferring my TWRP backup via WiFi.
I planned on switching to CM11 and see if I can't get it to work after that.
So I saw that Samsung had pushed out the Lollipop updates a while back. I thought I'd do an upgrade. I've rooted, which I assume is the reason(or Knox - or both) that I can't do the OTA. So I figure I'll plug in and find out how to push the update...at which point I learn that although I am able to charge fine, my tablet is not connecting to any PCs. I've tried 3 different computers, 2 running Windows 8.1, and one running WIndows 7. No luck. The Windows 7 machine initially said it loaded an unknown USB device, but after I installed the Samsung drivers, it does the same thing as all the others, acts like it doesn't see anything. No device in device manager.
So, I'm not sure how to proceed. I feel like I should get USB functioning before trying to update? I can still boot recovery and try stuff from the SD card as well. Regardless, I'm not sure what I should do first, I'm concerned that USB connectivity appears to be broken.
Thanks!
Does mtp work? Can you see your internal storage and sd card?
You may have disabled mtp in your recovery on accident or on purpose and forgot you did. I would check that first.

You can't disable mtp in stock recovery and even if you could it wouldn't affect download mode.
