No pc connectivity at all - EVO 4G Q&A, Help & Troubleshooting

When I connect my phone to my pc it will charge, but nothing else. No connecting sound or notification on either the phone or pc. What's strange is it was working just days ago. Anyone have an idea?

What of are you running and did you enable debugging

The last rom I flashed was the rc version of cm6 and I had no problems for a few days afterward. And yes debugging is enabled

Wow, did you try a different USB port on the PC? Also did you tried connecting the ph to a different pc? My guess is may be the Rom but try a different USB port and pc first to confirm that...

If you are using the piece of crap USB cable that came with the phone, try a different cable. Seriously.

My phone refuses to connect to computers.

I've tried 3 different cables on 3 different computers and it hasn't worked on any of them.. 2 cables are Samsung and 1 was a blackberry cable. All 3 computers are windows XP. Could that be the problem?

No I don't think its XP. Did you find the epic drivers and install them?

Are you plugging the cable into just any USB port?
Computers usually have like 6 or more usb ports... Usually only two of them are the primary. The rest are technically a USB hub.
On a normal desktop tower, you want to plug your phone into one of the USB ports immediately adjacent to the network port. They are usually side by side, Network jack, and 2 usb next to it.
You may have to look up how to clean uninstall the samsung driver, then reinstall it before you ever plug your phone into your computer. Then you want to always plug it in the same spot. USB ports often act like individual devices. Even though the driver is installed, and your phone may work on 1 usb port, moving it to another port, it may fail to recognize it.
This may be a setting on your phone, or it may be a setting on the pc. Also, when mounting and unmounting your phone, make sure you use Windows XP safely remove hardware, or the unmount option from your phone to prevent it from failing to recognize at a later date.
Wow ill have to try that later, thank you for the info.

If that still doesn't work, I rebooted the comp while still in usb storage on my phone, which finaly made it recognize... good luck to you though!

Make sure your USB debugging is off I had to turn it off for some ROM's I don't know why but I did. Also If that don't work go to the market and download "Multi Mount SD-Card Lite" This worked like a charm for me especially the widget, but for the free version you can't have Ad Blocking on.
Same thing happened to my Hero back when I was first learning how to root the thing. Outside of computer and cable problems, it has to be your phone. I have to ask though, is it at least charging when you plug it in?

USB debugging problem

I plugged my phone into my computer today, and noticed that my USB debugging didn't come up on my phone. I'm not sure what happened, I can't figure it out. My computer doesn't recognize my phone and my phone doesn't start running USB debugging. Its checked on my phone but maybe my drivers are screwed up somehow. Anyone got any tips?

usb connection to computer
What is it that you are trying to do? If all you want is to see the phone from windows and transfer files, you want debugging off. USB debugging is for using adb commands, or tools that use them, like for rooting.
If you are sure that it is not software problem with your PC (it worked some time ago, you didn't change anything, etc.), than try to clean USB port with soft tooth brush. The USB can have some problems due to oxidation.
I'm trying to go from AOKP 31 to something newer. But my computer used to show me my phone but now it doesn't do anything.

Galaxy s2 will not connect to any pc

I just bought a galaxy s2 running stock gb on ebay and whenever I plug it in any pc it only charges. There is no usb notification nor does computer play a sound when the phone is connected. The phone makes a sound and just charges no matter what I do, I have tried usb debugging on/off and nothing. When I go into wifi/connection settings and select usb mode it says to connect a cable when the usb cable is already connected. I have tried many usb cables including the original samsung one.
Did I just buy a defective phone or am I missing something?
You need the drivers, either Google it or wait for someone to post a link, your call.

Try all usb ports as well! Even without the drivers you should still be able to use it as mass storage device

Are you using a data cable and not just a regular charging cable? You still see the option to connect mount the SD card evn without the drivers.

I'm not sure if this works on stock gb buy try going to settings/storage. Then press menu and if another settings option comes up then go there and see if there is an option to mount as mass storage device

Having the same issue, can it be that I am using a backed up ROM? I know that there are times when having a backed up ROM changes your system to R/O instead of R/W

MY PC basically does three quick beeps, like the ones it would make when connecting to the phone.... the only difference is when properly connected it would make one beep. I have 6 USB ports and have used all of them. In Root Explorer it states "Cannot detect SD card" that happened after i clicked on SD card to see what files were there.
I did a fresh flash of a ROM and now I am not having issues connecting to PC.
similar problem
I have the same problem of my gs2 not connecting to the computer. The only difference is that it isn't new, and I've been connecting to the computer using the exact same cord for a while.
I'm not really sure what the problem could be, it was working fine as recently as yesterday
Had the same issue I had to send it in for repairs USB port on the phone was effed up

Install moboro on ur PC, make sure developer options is enabled, and debugging is ticked, moboro will install needed drivers for phone to be seen, check to see if the phone is rooted y downloading root checker from play store, if it is rooted it may be an issue with the rom, try downloading Odin and putting the phone in download mode, Odin should see the device and say "added", if so go to sammobile.com find ur devices newest firmware and DL the file, use odin to flash the firmware on the phone, should solve all issue, u can also use Odin without being rooted too so, if u need more info, links or whatever, just let me know

WARNING
I had the same problem about a month ago. I had sent it to Samsung and they replaced the USB part of my phone. So if nothing works, DON'T PREFORM A FACTORY RESET IF YOU'RE ON STOCK! THAT CAN MAKE YOU STUCK ON A BOOT LOOP! but if you're lucky then everything will work fine. I only say this because it happened to me.

[Q] Not recognizing when plugged in

Long time lurker, finally joined up. Had realized this was a problem for a bit. But, I would like to root my phone and with it not recognizing, I'm not seeing how it's possible. Tried all the normal things, restarted computer (MBP 17") restored phone to factory settings, tried different cables, played with all the different default connection settings, turned usb debugging on and off. The phone just charges, nothing shows up to choose connection type like it used to. The GF's Evo3d works fine. Tried doing some research to see if there are different drivers for the mac on the regular evo4g vs the 3d, and it doesn't appear to be. Kinda at a loss of what is going on. It is possible that the pins inside the usb on the phone are damaged?
Any direction would be appreciated.
Thanks
Steve
If there's no way for me to figure out how to make it recognize, is there a way to root and install a custom rom or ICS without manually connecting it...ie wifi?
Just as a basic troubleshooting step, you might consider trying to connect it to a different computer.Or test using a different cable.
And yes, USB ports do fail on Evos sometimes.

Tried multiple cables with my laptop and GFs...starting to think it's the actual micro usb connector in the phone. Her Evo3d works on both computers and with several cables...mine doesn't with any. May try to complete it by accessing the files through bluetooth...not sure if that's a good idea or not though

Unable to install drivers Help

I hope I posted this in the right subsection.
I used to be able to connect my s3 to my computer just fine. Now When I try to connect it, it randomly connects and then disconnects after a few seconds going back and forth like that. My computer doesn't have enough time to install the drivers for it since it disconnects on its own like that.
This is not my computers problem since it wont connect to my other computers. I even tried reinstalling the os on my pc for new set of drivers, but no luck.
Im sure it has something to do with my phone. My phone is rooted, so if any fixes include being rooted, Im good with that.
I tried changing from mtp to ptp connections, removing the battery, trying different usb ports and cables.Tried with usb debugging on and off too.
Im at my wits end here. please help!
Your usb port may be going bad. Check the port for any built up lint or other crap. Also check the pins, make sure they are all there and straight.
I tried another USB cable and it worked
