Have you tried another phone? Or device with micro usb? And does device manager recognize it at all? Even as an unknown device?

Have you tried connecting other devices? Is it micro USB A or B?

Just for starters why don't you turn off your phone and plug it in and then turn it back on. See if your computer recognizes a device while booting up. That's a start.

Have you taken the cable to another computer? Do you have access to another computer?

Computer doesn't recongnize mass storage and Kies cannot recognize phone either

Apparently, when I plug my phone in computer to put some files, pictures to phone, my computer doesn't recognize the phone's mass storage and neither do Kies
The message from the computer is : USB Device Not Recognized. One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message.
I thought there was something wrong with rom i installed, and tried unroot the phone, restored it to orignial rom. However, the problem is still there.
Please help me . Thank you for reading.

Did you use the USB cable that came with the phone? I noticed mine doesn't come up on the pc unless I use the cable that came with it, otherwise with any other cable is just charges and nothing more.

I would suggest buying a new cable and trying that. Seems a lot of users are encountering this lately. The wires that carry data fail, but the wires that carry power still function. It doesn't have to be a Samsung branded cable, but one specifically for charging/data for the SGH-T989. It happened to me both on this phone, and my Transformer. Both times it was solved by using a new cable.
Your local electronics store should carry what you need. Good luck!

I tried it. No help :/. I think it is the phone's usb port that makes this problem. Probably I'll send it to samsung company to have it fixed.

Before u diagnose the phone as the issue i would check and try plugging it to another pc besides the one that doesnt detect it because i have the same issue with my main pc. When i plug it it opens up as an unreadable drive, it wount open or anything, but when i plug it to my laptop it works perfect.
kind of wierd but it works. i also tried installing kies and didnt help at all. now it it still doesnt work than yea probably the phone.

Yah, it's probably the phone. I tried plug it in my brother's laptop and computer (Kies installed) and still nothing happens.

Allgamer had a similar problem. Turns out it was his cable

Try the free wifi explorer from the marketplace.

Also remove sim, sd card, and battery for a bit then replace. Also, get the most "official" cable you can. I'm working with an old evo cable and an old g2 cable. Some of the car charging ones/generics won't play nice. Try blowing (light laughing allowed) into the port.

Finally!!
Ok here is what i did:
1-enable EHCI on your computer from device manage >> http://www.intel.com/technology/usb/ehcispec.htm
2-took a portable toothbrush with isoprop (swabbing alcohol)
3-took my phone to the gas station ...25c air and dried the crap out of it
4-wipe/reset my phone from fast boot menu (not android menu)
5-got an LG "B" data cable...
voila monsieur !!!! i dont know which was the silverbullet but i aint complainin.
However, it was still nice to know that Samsung is a no questions asked manufacturer.
Someone was having the same issues as mine in russia, and he said ICS 4.0 did it and is waaaaaaaaaaay better for this phone. Im gonna give this to a friend and WILL NOT touch these till ICS 4 officially comes out here. Tooo much hassle and ive got too much info riding on it (phone). <<personal opinion

[Q] USB doesn't work with computers, only charging. How to flash ROM?

for some reason Sony Thailand couldn't declassified, been like this since the first day. Going back and forth to service center tons of times and they COULDN'T FIX IT. My dad's Xperia Play won't connect to ANY computer, no bing-bong sound when plugging no nothing, not see anything on the phone except that it's charging, it's like the computers aren't existed, only the power gets through.
Now Sony still not fixing this problem, so for this old phone how can I unlock it and flash ROMs without a connection to PC? By any means.
Thank you!!

Have you tried changing usb cable? Maybe it is broken (mine got broken after a week or so, and it was the original one come with the phone of course), since it's impossible that they sold you a device with damaged micro-usb port.
Or maybe it is the usb port you're connecting it to: some PCs have a lower voltage in front usb ports, so you must connect the Play to the rear ones installed on the motherboard of the PC

I think they sold my dad a faulty device and when he tried to claim it after a week they didn't want to replace the phone so they told him they could't fix it. This country's Sony is known to sell faulty devices, my last Xmini was also broken...
and yes I did try other cables, Sammy, LG and some chinese made, nothing works. They did work with my Nokia N8 and S3, however. All the ports in my PC have failed, also.
so I can do nothing, stuck with RAM hungry 2.3 bloated ROM without any solution to make it faster.

You can enter fastboot mode by keeping pressing the search button while connecting the Play to the PC.
If it's into fastboot mode, the led goes blue.

Unlocking bootloader and custom recovery without PC?

So my computer doesn't support USB C.
I tried to get a USB C to USB A cable, but I read all kinds of warnings on the internet about how these cables can damage the device.
And since I can't find first party accessories in the place that I live, I hesitate about buying alternatives.
Is there any solution? I only want to unlock the bootloader and flash a custom recovery.

Some USB A > C cables can cause problems, but there's a list of cables that have been tested to work here: https://docs.google.com/spreadsheets/d/1wJwqv3rTNmORXz-XJsQaXK1dl8I91V4-eP_sfNVNzbA/edit#gid=0. Look for approved cables with "Benson" in the Method column. I have a Cambond and a Choetech cable, both work fine.

I snagged a USB 3.1 card for my PC from newegg. Works flawlessly and even allows for quick charge through my PC.

Thanks guys, I will look into your suggestions and pick one.
I take it as there is no way to unlock the bootloader without a PC?

Correct, however if money is limited and you don't want to wait on shipping and can get an OTG type C you can use my recommendation. Although it won't charge it does allow for data transfer, so unlocking bootloader and flashing twrp.

Can you not buy from the google store online? I thought they shipped everywhere.
I know its kinda expensive but its where I got mine from and knew it would be a good cable from them. (Tested and it was).
Also picked up a spare charger at the same time.
