All of a sudden phone will not connect to pc.

Alright I am running cm9 and have been for weeks with no issues. I got the new galaxy s3 and installed the drivers on my pc to root it and all that. I want to change roms on my E4GT though so I go to plug it in and it charges but will not connect so I figured I had to reinstall the usb drivers for my e4gt so I did and still nothing. I am in no way a newb i have flashed tons of roms and I know I did not do anything wrong. I believe I am just missing a driver. Can someone point me in the right direction? I have the latest version of kies installed and the drivers straight from samsungs website.

Made a little progress but not much. I realized I didnt have usb debugging enabled so I enabled that but now when I plug it in it just says usb debugging enabled instead of asking if I want to mount as storage device I have tried rebooting phone and pc several times. I am running out of ideas.

Did you get the drivers by installing Samsung Kies?
I ran into a similar issue once. I removed all Samsung software with all devices disconnected, did a reboot, re-installed a new copy of Kies, and when I plugged in the device, I opened the notification and told it to skip searching Windows Update.
Also, make sure you are plugging it into a powered USB port, so one on the back of your computer. Sometimes laptops don;t provide enough power either. My girlfriend's OG Epic refused to flash on my MacBook Pro, but worked fine on a desktop.
Latest version of Samsung Kies: http://org.downloadcenter.samsung.com/content/SW/201105/20110512115717796/Kies_2.3.2.12054_20_1.exe

Thank you very much i will give it a try and report back.

Actually no i did not get the drivers by installing kies because I already had it i got the sprint sph d710 usb drivers. Should I uninstall those and just install kies?

Well this is a rediculus problem that I am having now.. I cant install kies because it is saying I am not connected to the internet and I clearly am as I am posting this on the same pc that I am trying to install on.. I have tried rebooting the pc that does nothing.

Alright I got kies to install but still the same thing when I plug the phone in it says usb debugging enabled i really have no idea what is going on.

have you tried different ports on your computer, also have you maybe tried a different computer. If not it could be phone issue I fried my usb board on mine. best bet to try that is to flash another rom if possible and see if it you can connect to computer

I have tried different ports but not a different comp. Ya I am gonna flash a new rom and see if that helps. How could I have fried the usb board though? I havent touched the phone in days since I got the gs3.

Yup Just flashed the new Super Nova rom and now everything is working again, thank you very much for all the help and if anyone hasnt checked out that rom yet they need to its awesome!

[Q] USB/Computer connection issue

Hello XDA!
I don't want to post a wall of text (not that tall of a wall, at least), so, I'll try to get to the point quickly. And yes, I have done a lot of searching, both on XDA and Google, and that will be proved soon enough with the solutions that I've tried so far.
The problem I'm currently experiencing is when I connect my phone to my computer, it charges but it isn't recognized. There is no USB notifications, no phone in My Computer, and no Windows pop up, whether it's a pop up asking me to install drivers or an unknown device has been connected, nothing. Mind you, everything has been working flawlessly, this just randomly, and I really do mean randomly, started happening. The phone has never been dropped and there is no water damage. I'm still using the USB cable that came with the phone. And, if it matters, I'm rooted, running the leaked LI8 JB ROM, stock kernel, and UVLEM baseband.
Here's a list of said solutions that I've tried so far:
Using a thin paint brush, wet the tip a little with alcohol and tried cleaning out the USB port
Connecting to a different computer, connecting with a different cable, connecting to any other USB ports on the computer
After making Nandroid backup: Data wipe/factory reset, flashing a different ROM
Remove Samsung USB drivers and reinstalling, also tried installing Samsung Kies
Uncheck USB debugging and restarting, checking USB debugging and restarting
Dialled *#7284#, select Modem, then reselect PDA, changing Qualcomm USB settings and changing it back to MTP + ADB
Turn off phone, remove battery for 30 sec, reinsert and boot up (soft reset to reset internal circuitry as described by a Samsung live chat service tech)
I might've left out a couple, but please do enlighten me of methods that you might know, I'll be sure to try it or let you know if it's already been attempted.
..also, when connected to my PC, under Settings > Battery, it shows "Charging (AC)" IIRC, this should be showing "Charging (USB)".
This next attempt stood out to me. I decided I would try and go back to the stock firmware, one where I would have to use Odin3. So, I put the phone in Download Mode, open up Odin3, connect the phone, and I get a pop up in Windows! It's trying to install drivers, and fails. I can't flash the stock Samsung firmware if I wanted to, even for warranty purposes. I do currently have the USB drivers installed, but my PC hasn't gone through the driver installation for when the phone is connected to the computer. So, I'm assuming that is why this is failing? I'm not entirely sure. But, when I saw this, I unplug the phone and plug it back in numerous times, to rule out that this might be a hardware problem. And, every time I plug it back in, it tries to install the drivers but fails. So, it's detecting my phone in Download Mode. I reboot and hope that it will detect normally, but no, it doesn't...
As a last resort, I went to Samsung.com and chatted with a service tech, he runs me through two procedures that I haven't done, the 'soft reset' and a 'master reset', which is done through Settings > Back up and Reset > Factory Data Reset. Neither worked, so, he then checks my IMEI and finds that I am still under the 1 year warranty and files a ticket for repair service. I asked him if there is a replacement warranty and he says that is done through my service provider (T-Mobile) with the Premium Handset Protection service, which I didn't add. Not because I didn't want to, but I can explain in later posts if someone is interested in why it wasn't added. So, now I have the return label in my inbox ready to be printed, taped onto a box containing my phone, and sent out. But, I can't go through with this because I have a custom ROM on the phone. There is no counter because I've already used Triangle Away, AFTER this started happening.
I am completely stumped... Any information is greatly appreciated!
EDIT: Also, I've disassembled the phone to check the MicroUSB port to see if any pins or prongs might've came loose. Everything is in tact.. I also wanted to see if the MicroUSB port was replaceable because I was able to find a spare MicroUSB ports on a website. But, it seems that the port isn't easily replaceable. It doesn't look removable, and I'm uncertain if it can be de-soldered to solder a replacement one on. Also, some thing caught my eye when I had it disassembled. There were two components of the phone that had SGH-I747 imprinted on them. I wasn't able to take pictures as I was in a rush to get it put back together, but thought it was of interest to bring up.

How do you have a custom ROM if you flashed the stock one? I'm confused..
Try installing drivers through the toolkit.

If windows recognized it in Download Mode, keep trying to unplug and replug the cable in the same and different ports until it installs?
This happened once on my Galaxy S 4G.

Uninstall all related drivers, kies, etc. Restart pc and download and install these drivers. (Should be latest)
http://d-h.st/zya
Or download and install latest version of kies. Drivers included.
Try connecting again.

I was never able to flash the stock firmware because my computer fails to install drivers for it. I've also tried using the drivers from the toolkit and it gave me no results.

I just hopped on right now after trying the different USB ports on my computer while in Download Mode. Same deal, it detects, tries to install drivers, then fails. It's coming up as an Unknown Device.

I currently have the latest Kies installed. I'm going to uninstall and give that link a shot, though. Hopefully, Odin3 will be able to detect it, at least, so I can get the stock firmware back on this thing...

Thank you for your input, but I doubt this would work in my situation. Ive tried connecting it to my laptop and another computer in the house and they both do not detect the phone. However, i would consider going that route as a last resort if there arent any other ideas.. i just need Odin3 to recognize it so i can revert and send it back in..
Any other suggestions, XDA? And thank you to those that responded!

SGS3 failure during odin flash; stuck

So I somehow during my flashing adventures got to the point where my sgs3 would no longer recieve 4g/3g signal but only 2g. I reverted to stock rom, still had the issue (4.0.4), and it wouldn't let me upgrade to jelly bean, it told me "unable to connect to network" when I tried system update. So i took to the fixing my imei number, which apparently did something as I was then able to connect to the server and upgrade to jelly bean, with one problem; I was still getting 2g. I continued to try to use the rest of the guide (http://forum.xda-developers.com/showthread.php?t=1801997) but on jelly bean my computer would no longer recognize my phone through odin or qpst, etc, but I could view the files. I could do nothing to get it to bring up a port I could connect to. I downloaded/installed/uninstalled/installed the driver many times and still couldn't get it to connect. Like an idiot I tried through odin to flash back down to 4.0.4 so I could reestablish connection and continue fixing my 2g signal, but it quit halfway through and said "Can't open the serial(com) port" and didn't flash, so whenever I tried to turn on my phone i got the firmware upgrade error and telling me to connect to kies and use recovery mode, which I did. However, Kies wouldn't recognize my phone through it. It's drivers never connected, and it just sits there saying connecting. Samsung's help/support over the phone was literally WORTHLESS ("indian accent" Take da battery out ov your phone, sir. Wait 10 seconds. Put it back in..... They literally told me at one point "Go into menu, settings..." me-" In my phone?" him "Yes that is correct" me "Thats my problem dude, I CANT TURN IT ON") and I currently have a ups label to ship it in to get repaired, but I want to know if there is anything I can do before sending it in and waiting 5-7 days without a cell phone. Thanks in advance to help

Odin the stock4.1.1 software pre rooted or not.. My phone froze at samsung screen but just reboot and it will be fine
Sent from my SGH-T999 using xda premium

Did you even read the post...? haha it's not that simple, or otherwise I would've fixed it.

make sure you are using the samsung cable that came with your phone.

I don't have the cable that came with my phone, but that has never stopped me before and I don't see why It would affect my computers ability to recognize my phone if it was perfectly capable of doing such before.

So, the system won't detect anything when you plug it in, not even after a reboot?
Well, there are a couple things you can try.
First, uninstall Kies and the Samsung USB drivers.
Reboot.
Install the drivers in my signature (they are older ones, but stable - unlike the newer ones).
If that doesn't work, try a new cable and USB port on your system.
If that doesn't work, it's bad hardware.
This will end with you flashing a stock image, probably.

Glad you got the problem solved. The reason I said to use the samsung cable is that I was able to root and flash my first rom with a non samsung cable then after that it wouldn't work unless I used the samsung cable.

[Q] Problem regarding super user and USB connection

Dear All,
I have encountered a problem with my note 2 that unfortunately closes a lot of doors for me to fix. I thought about asking you guys and hopefully this has not been asked before. Ok so my problem is that I had rooted phone ages ago and i had SuperSU installed with the root. Later on some official update came out and I let it update. After that I might have lost my root there and then not sure though. When I try to do something in root it won't let me, also it fails when trying to change super user app. What is killing me mostly is that any computer I connect using different cables, won't recognise my phone, as if it was not even connected although it charges normally. At first it was sometimes charging and not, sometimes freezing if connected to the USB. It might be hardware related but I want to try to fix this issue first to be sure. I can't even use Odin since it's not being detected so unrooting and going back to the seller is out of question.
Can anyone help me please? I am thinking of trying custom firmware through sdcard installation but i cant even install CWM and when using official recovery the package is not accepted. (signature issues). There may be some easy workaround I do not know of hence me asking you experienced guys.
Big thanks for reading this and hopefully helping me.

So you mean odin is not detecting phone in download mode ?
Try connecting the phone and see if adb works but I don't really think it would work. Try another cable. Could be that usb port is damaged.
Try another recovery.

No, Odin is not detecting the phone although it starts charging like normal. I will check adb later tonight when I am on my home pc. I have tried in total 4 different cables same result. I have used 3 different operating systems on different computers, still not detected. Usb port might be damaged but I don't think they will be happy seeing its rooted.(they being the store i bought it from, that is why I have not gone to them yet.

I have a similar issue since 4.1.2 however my phone is recognized by computer and odin in download mode, are you sure you tried it on download mode?

Yes I have tried download mode, that's why this problem is killing me :/ The root access is completely unusable and not working too.

[Q] USB Device Not Recognized

I bought a Korean Note II (SHV-E250S) and my computer wasn't able to recognize it from the get-go. Now, I installed a rom that caused my phone to be stuck at the first screen and I can't connect my phone in download mode to restore it. I tried a different cord (supposedly OEM), reinstalling kies, downgrading kies, installing just Samsung USB drivers, uninstalling the unknown device driver, shutting down the computer, installing updates, reupdating kies, emergency software recovery/upgrade, switching USB ports, USB debugging on/off (when the phone still worked). I'm literally out of things to try. Any help will be appreciated.

No. Sorry. I made a back up in clockwork recovery but I get an error MD5 mismatch.

Device Descriptor Request Failed (Code 43)
The phone is now soft bricked and I get Device Descriptor Request Failed (Code 43 I sold it to someone with a T-Mobile rom and N7100 clockworkrecovery. They updated clockworkrecovery and now the phone just boots into recovery and then restarts. I cannot get the phone to connect to the computer at all. I get an error. I have tried talking with support but they tell me to try everything that I have already done, such as; different usb ports, cords, computers, had the usb port replaced, reinstalling software (all of them), and restarting download mode.

any development?
I have the same problem, device descriptor request failed.
Luckily, im not bricking the phone yet.

Nothing

Some search on google told me that we need to fix the usb pin.
Im not yet trying it. Im afraid it will cause another problem. So i leave the phone as it. Even though i cant do anything to update the phone. (Maybe i do have change to update the phone, but it will take a risk)
Try to fix your usb port pin.

On the phone? I had the pins on the USB port replaced and I bought a new USB port from China with no help. I also tried 5 different computers (both mac and pc) as well as different oem USB cords.
