How can I tell if my USB port is busted or my phone is corrupted? Only charges now.

Charging over USB works fine no matter the cable or the connection but it no longer will show up in Windows on any PC as a device. I tried flashing roms, changing cables, and doing the usb fix with Terminal listed in the sticky but it doesnt connect or will it know it's connected to a PC.
Can the port be broken so data no longer works but charging does?

its not the phone its the computer, try another computer

I have tried 3 which is why I wonder if my phone is broken, but it charges fine.
On all PCs the charge light comes on the phone with no problems but with all of them none of them detect a USB device being plugged in.,
Even in recovery if I do a USB-MS mount nothing happens.
Can the usb port break so that it charges with no issue but wont connect to a PC?

Does the phone recognize your sdcard?

I think the solution to your problem can be found in this fix

The USB port on my Evo 4G will charge but won't show up as as a device on my laptop. If I hold the USB cable at an angle, though, it does show up. I think mine is busted, maybe that's the case for yours.

Yup. Last night I completely wiped it and had the phone format and set it up fresh.

Do you think the cable is busted or the phone? I have tried multiple cables on multiple PCs and nothing happens.
So then it is possible for the phone to be unable to connect but still charge fine?

Have you tried mounting when in Recovery?
It really sounds like your cable is weird. The power lanes are on the edges for USB, meaning that the port on the phone is probably physically fine. The cable, however, is vulnerable to damage on any one of the four wires.
If nothing works, then perhaps something internal is busted. What do you need to transfer from your computer? Perhaps you can do it by connecting to your computer through WiFi for mounting the SD card and adb?

Its your USB port on you phone, theres 2 pins or smoething broken inside your phone thats causing the problem. I had the same problem on my Evo were it wouldnt connect as a storage device and would go into car dock mode. I took it to sprint and showed them the problem and they replaced my phone. As long as you dont have any physical damage such as the screen being cracked you should be fine and they should replace it free of cost.

Make sure that your cable is not one of those charge only, car charger type cables. Typical car charging cables don't transfer data.

Yeah, that's pretty much it. If I wiggle it just the right way the computer will see something but it will go away as fast as it shows up. Doubt Sprint will do anything as the phone is a few years old, I dropped the protection plan, and it's rooted to heck.
I'll just keep it running until this fall and upgrade when the new Nexus line comes out.
Hopefully.

[Q] [Help]. Strange issue with micro USB port.

:crying:
I got my problem yesterday. My phone (GSM version) suddenly didn't charge when I plug with charger.
I try to connect it with PC, PC not recognized it, still not charging.
Reboot to bootloader, all fastboot command work fine (this thing is what make me believe my microUSB port doesn't die). So I flash stock 4.2.2 with Gnex toolkit.
Now the phone charge, adb and mtp work fine when I connect it with PC, and with wall charger nothing happen when plug it in. I did try some charger, it's same, still not charging.
Please help!
p/s: Sorry for my bad english but I hope you can understand what I mean.

There have been issues with the MicroUSB port in some Galaxy Nexus phones. I know this because I was involved with a thread over on the Android project forums having to do with very strange issues of the screen coming on all the time. The discussion is here: http://code.google.com/p/android/issues/detail?id=39625
We finally seem to have resolved the issue by very gently bending the tiny pins inside the phone's MicroUSB port upwards towards the screen.
You have not mentioned the same issue, but I can imagine that all sorts of strange activity could be attributed to a faulty MicroUSB port. You should have a look at comment number 161 in that thread and think about trying that. Be very careful! Be very gentle. If you break it, it;s not our fault! ;=)

Lost usb connection and quick charge after rom update

Hi guys,
I had a xiaomi.eu beta rom installed from feb/18 and i decided do update to the last beta available 8.4.28 through twrp. After that i lost quick charge and my usb connection. My pc (or any) dont recognize my phone, when i plug the usb into my pc nothing happens, nothing new in the device manager. I tried different cables and charges. Cleaned my phone usb type c port with isoprophyl alcohol and a electronic contact cleaner, didnt fix. I decided to do a full wipe, installing a Global stable 9.5.2 do see if it would fix my problem, but it didnt workout. After that i foundout thay i lost my twrp and a generic recorery from xiaomi was instaled. Yesterday i got a update via OTA to 9.5.4, didnt fix it. Now i have a phone with slow charge, no usb connection, no twrp, no root. My only solution now is to find an APk that root my phone so i can install twrp using flashify and try the rom from february i was usong before all of this. Does anyone have/had this issue?

Does this also happen when connecting with other computers?

Yes, i tested with my laptop and my computer at work. Also, my otg doesnt work. I can reboot to Fastboot mode, but i my pc doesnt regognize this way too.

i have the same problem. currently i am on V9.6.1.0.NAGCNFD. and i lost my USB connection to my pc. as well on all QC chargers i have, i cannot charge my device any more. it starts to charge for 2-3 seconds and then stops charging. slow charging via regular usb ports/chargers is the only function left on the built in usb-c port.
i tried various pc's, cables & chargers.

I fixed it on my mi5s. it was actually a hardware problem . after changing the lower board containing the USB-C connector inside of my phone, it all is working again.
the board is available for a couple of USD on aliexpress.

Just wondering - did you manage to fix this problem? I have the same issue - but AliExpress USB-C module replacement didn` help.

Mine is working fine since i replaced that module.

Your USB port is fried.

Question {SOLVED] Cannot connect ZFold 3 to PC via USB (only charges/no transfer options)

When I plug phone via USB into PC running Windows 11 the phone will only charge.I don't get any options on the phone for file transfer and the PC doesn't detect it. Any tips. It's usually pretty straightforward.

maybe a driver problem?

It came down to the cables I was using.
The Huawei cable I use for the 65W charger didn't work. The Huawei cable for the 15W Wireless Charger didn't work. Found another cable in my cupboard (don't know what or where it comes from) but it now works and I get the options for transfer on the Fold and it shows up in PC's file manager.

Thanks for replying. It was a cable problem.Doesn't seem to like Huawei cables.Very strange.

So the Huawei cable ends are Purple and Orange in colour. Both cables don't work for transfer but only charge when plugging into your PC. The cable end which is White works fine.
Just in case someone else runs into this problem since the phone doesn't come with a charger and cable and you might use your Huawei cables and find you can't connect to your PC to transfer files but only charge.

That isn't new. Samsung had before issue where if you used non Samsung cable the Samsung phone will nag about port was wet, when it wasn't. But now it seems Samsung finally got rid of that limit so charging with any USB C works now. But it seems you need to use original cable for phone when it comes to transfer of files.
