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 ME!!!

My Galaxy Nexus isn't charging or connecting to my computer. I've tried different USB ports, wall adapters, and USB cords and nothing. I don't really want to replace the charging port. What can I do?
Thanks in advance.

Delete this thread!
I accidentally put this in the wrong section! Thanks!

Check the charging port for Lent and stuff with a little pin or something..
That's what happened to me in the past
I cleaned it out and start to work again

Of what cujo said didn't work you have no option but to replace the port or buy an external battery charger.

In a pinch you can rig up a temporary charger using the POGO pins on the right side of the phone. Just wire the corresponding red/black wires from a cut up USB cable to the correct pins (you can find the pinouts online). The trick is getting the wires to stay on the pins - you can try packing tape. I know this is kind of a dirty solution, but it will work in an emergency until you can replace the usb port.

Can you link me to the part I need to replace! And a video of how? And how expensive is the part in question? My Galaxy Nexus isn't my main phone but I just wanted it working again.

Well, there is no guarantee that it is the USB board - but you can purchase one on ebay for under $10. The part includes a usb jack as well as a ribbon connector that connects the jack to the main board. There is, however, a chance that you have a faulty main board, in which case, replacing the USB port is not going to fix your problem but the only way to really test that is to buy the part and try it out.

That's for a Verizon Galaxy Nexus, I don't remember which one you said you had but you'll want to be sure to get the right one.

Are you using the original charger that came with the phone? It's the only thing i have luck with.

I ordered the new port! But I tried the pogo port charging and it didn't seem to work.

Problems with USB connection

I had been somewhat unlucky and while charging my beloved FLO something went puf (literally). After that I don't have any USB connectivity. Charging my N7 works (very slowly), but no USB OTG or USB ADB. OK Fine and dandy if I wouldn't be total idiot and wipe system while trying to install new ROM before transferring ROM image to internal storage.
Now I have FLO paper clip able to go to TWRP but can't install nothing. As far I understand there's no way to enable wifi in TWRP.
Any ideas what would needed to be replaced to make my FLO work again so I can put some ROM on it and make it work again.
I'm not sure if USB daughter board would suffice and solve my problem. Any suggestions?

Either the USB port developed "dry joints" or the wide silver cable (LCM) needs to be re-seated on both connectors.
Disconnect the battery before fixing LCM cable. Here is advice on USB port repair.
Replacing the daughterboard PCB should be the last resort because it is unlikely that the touch function will work 100%. It would work if we had access to the touch calibration software - the problems are described here https://forum.xda-developers.com/ne...rivers-to-calibrate-touch-screen-usb-t3334898

I doubt re-seating would help or cleaning USB port, since it was something electrical happening with that *puf*. If my memory serves me right there was a smell of burnt electronics. I doubt that some shortage disconnected any cables.

Sounds like you need a new charging port and board. Easy to fit but difficult to get hold of one. Maybe purchase a broken Flo on eBay and extract the charging port board

Even tho charging works? The only problem is data part of USB connection. USB OTG will not work neither will it connect to a PC for file transfer/adb. But if connected to PC or plug device charges. I believe it will not charge past 80 or 90%.

Can't connect to PC except for charging

Hi. I wanted to flash Oreo RUU and root but I cannot connect the phone to my laptop except for charging. I get a message saying "USB device not recognised". I've tried 2 cables (HTC and anker) 3usb ports but to no avail. I've tried installing drivers through HTC sync but it doesn't work. I've tried to connect in bootloader, recovery, and download mode but same problem. Can anyone kindly help me? Thanks.

may be due to faulty c type connector on phone

Any way to test that?

If it does not recognize in PC try with an otg cable and pendrive. If it also doesn't work then it could be the connector.

is fast charge still working? on my htc10 the usb connector died after 15months and it started with fast charge not working and the pc connection was very unstable. In my case it was warranty and got repaired.

Firestick 2.gen, no HDMI signal, is it dead?

I've got firestick 2.gen and it's not working.
I've plugged it to working HDMI port in my TV and apply power to micro usb port, but there's no signal on tv. Tried on other TV but it's the same. Stick is hot after couple of minutes.
Is it hardware failure?

Have you tried unlocking it before this occurred? Mine did the exact same thing that I literally had to buy one. It appears there's a hardware revision with the tank that clearly prevents people from unlocking and maybe the clk component Amazon revised makes it hard brick? For some reason while unlocking it, it wouldn't get passed the "waiting for bootrom" after I tried countless number of times unlocking it with foil, some jump wire, and a wrapper. I would recommend just buying the 4k mantis instead the tank. That's what I did and its much faster.

I didn't try anything, it came to me like this so I don't know what happened.
Is there anything I can try to unbick it?

Idk if it helps for hdmi problems, but the unbrick thread is here:
https://forum.xda-developers.com/fire-tv/development/unlock-fire-tv-stick-2nd-gen-tank-t3907002

I tried that, with live Debian, but PC won't recognise the stick at all when I plug it with USB cable and shorting CLK and GROUND.
Is that means it's a hardware failure?

In lsusb you should get the mediatek phone message, in case you short correct and steady.
Besides that, if its a new stick, lets say up to a half year old, it could be one of the bootrom patched sticks.
What messages in lsusb showed up without a short?

There is no message at all, like I did not connect anything.

There isn't a message at all, even if you don't short the stick? The CLK resistor is fine?
You said it gets hot after a few minutes, so it should say something I guess.
Maybe check for cold joints at the usb port and measure the power level somewhere near the emmc (1,8v).
If you have an USB to TTL Serial adapter, you can take an UART serial console log. The UART pads are mentioned in the unbrick thread, see the picture.

Short or no short, no message at all, CLK is fine.
It gets very hot after few minutes.
I have USB to TTL serial adapter, have seen the pads and will try to connect that way and see what will happen.

Ok. As you know, connect RX->TX and TX->RX.
A power connection isn't needed, GND is enough.
Baudrate bootrom is 115200.
After bootrom the boot process switches to a higher rate, I would try 921600.

I just connected the stick to TTL adapter, but there is no log at all. Double check connections but no log, done this before so I know how to do it.
I think this means it's dead beyond repair.

If you like, you can use the stick for read/write tests with your e-MMC adapter...

Haha, you're right, will try that, thanks ?

Take a look here , in order to find DAT0 and CMD on the board.
You can desolder the whole e-MMC chip with hotair from the board too.

Ok, thanks.

I wonder if you could do that and solder in a new e-MMC chip with more storage? Is there anything hardcoded about the 8gb internal storage limit, or the type of chip that can be used? Though I lack the tools needed to accomplish such a job

Maybe some things gets checked at boot, like the Disk identifier (GUID), idk. Technically it should work. May be a bit undue for such a cheap device^^
