Phone not Mounting on PC

So my phone was mounting fine on my pc, and then all of a sudden it wasn't. My Nexus 7 still mounts properly and accepts developer commands, but the m8 won't (yes developer settings is on).
I tried wiping and flashing a rom clean and it still doesn't work, charges fine though. Any advice?

You might try a different cord.
Open Device Manager in Windows and then plug the phone in. Do you see it in the list with a little yellow triangle? Do you see Android USB Devices listed?

OP after literally messing with various driver files, 8 usb ports and 2 laptops, I dug out my old box of cables and found a taped up, on its last limb OEM HTC EVO 4g (not lte the original) cable. This thing has been through the ringer. But its exactly what It needed. I figured with the 3 cable I had already tried this wasn't the issue, but have you tried using an OEM cable? I guess that is all that works. Good Luck

Still trying to get it to work, have tried 4 cables myself. I might just end up having to return the phone.... Fastboot works in bootloader

Uninstall all HTC drivers and HTC Sync. Then connect the phone. DO NOT choose the option to automatically install any drivers.
Open Device Manager, find the phone. Select the option to manually pick the driver, and select the generic MTP device driver.
This is what worked for me, after countless attempts at re-installing various HTC drivers, different cables and ports, etc.

Bump. Still looking for answer to this. I have RUU'ed both to Sense and Google Phone editions and the problem still persists, the phone does not detect its connected to a computer and change to mtp accordingly. Only way I was able to get the RUU in there was through fastboot, which is again the only time I can access the phone through usb. Adb is no luck in either android or recovery.

Have you tried revoking the USB debugging authorization and then accepting the RSA fingerprint key again when connecting to PC?
Obviously it can't be an USB cable problem if you can connect to it in bootloader mode and use fastboot commands.

To clarify, the phone just charges when connected, it does not detect that it is connected to PC so debugging doesn't even trigger, neither does mtp. I don't even get the slow charging notification

Does it do the same when you plug it in and reboot the computer to "pick up" during boot up process? Or if you run a live CD? I never had an issue like that with my phone but I did have a similar problem with the USB external blu ray drive I bought some time ago. The pc just didn't detect it at all not on any of the ports until I rebooted my PC with the drive already plugged it and for some reason it picked it up. <Not a solution as I don't know what caused it to not be detected in the first place but still...
Not sure if it's an issue with the device(Phone for you, blu ray drive for me) or if it's a problem with the PC even though other things might still work for you as it definitely did for me(phone, headset, mouse, keyboard, usb extender + all the external hard-drives connected to it)...

Problem exists in all computers, Mac, pc, linux

Did you try what I suggest in Post #6 above?
This worked for me when I had the same issue. adb and fastboot would work, but it would not mount MTP.
And just in the last day or 2 I helped someone else with the same issue and fix.

The phone doesn't show up in device manager.

Have you modify the Kernel? (Applying some settings for example)
I browsed over the web for this issue and found some people with the same problems. They solved by removing the settings applied on the kernel or flashing a new one.

I've flashed various kernels and ruu, still same result

HTC One m8 (Android 6.0) not connecting to computer

Hi,
So I got fairly sick of HTC's Android 6 update (Crazy amount of bugs) and decided to install CM-13.
A problem arose then when I tried to unlock my bootloader, the computer wouldn't detect my the one m8 in fastboot mode even with android studio and usb drivers installed or standard mode.
I installed HTC sync manager and still no good.
I tried different cables and different computers (one win 10 the other win 7).
When the phone is in standard mode and connected to the computer the usb symbol comes up and says charging only,
if i click on this and select file transfer mode the screen just greys out and stays like that until i click home/back.
This option comes up only once (I need to reboot to get it again).
I found another thread that says to install "AndroidHtcsync2.apk" I tried this and it didn't work.
Thanks

Maybe, like me, you have a broken USB port that will still allow charging but no data connection

That might be it, only thing is i was able to send files no problem a month or two ago before the update.

You need to be in bootloader-fastboot mode for fastboot commands; they won't work booted in OS or in bootloader (I think one of those is what you mean by "standard mode"?).
Other than that, Win7 is more reliable. And USB 3.0 is known to cause issues with USB connectivity on this phone, as well.

Sorry that wasn't clear. I was actually in fastboot mode when sending the commands.
The windows 7 computer I tried it in had USB 3.0 ports as well so that might be it.
However I wiped the phone after failing to flash CM and it fixed most of the bugs I was having trouble with so I might just leave it this way.
Thanks for the help

Oneplus 3 does not connect to pc

my oneplus 3 does not connect to my pc. I have tried turning on and off developer options, turn off and on oem unlocking and usb debugging. I change the usb connection to mtp from charging but does not change. Also does not recognize it when i connect to pc. Also does not pop up on status bar and i checked portable devices. I also tried installing the oneplus drivers. i am on Android 7.0 freedomos-2.5. Any way to fix this issue? i might try to update freedomos because im on a old version of it.:crying:

Windows? If, yes windows drivers are the problem.
Try to other pc, to see if it works., first.

I have tried it on both my PC and laptop with both windows 10. Does not work. My PC also has windows 7 still seems to not work. Are there any other drivers i might be missing?

i have also done some research that you should update your drivers from device manager. I dont see anything related to my device. i went to portable devices nothing and i dont have a other devices section in device manager. Any help?

What recovery?
Try to flash latest twrp. I use blu-spark by eng-stk. You can fla**** thru recovery or Flashify app.

i am on the latest twrp. will blu-spark help fix it?

ive also found out theres no kedcom driver when i go to fastboot. i even reinstalled adb drivers to insure its there but it does not pop up.

You'll need to remove drivers reboot, install correct drivers, reboot and then be nice to everyone you ever meet and it'll show up. It's a real pain but you can get there. XDA tutorial all the way there!

I once have kind of youre problem connecting to my laptop (win.10). But, at work, on that laptop, connection was ok (win.7).
I reinstal windows 10 and connection works fine, since.
I allways use latest TWRP & version of rom. I can't tell for sure what it's goin on with youre phone.
If i was in youre situation i format my phone (this will erase ALL in youre phone). And if PC still does not see the phone reinstall windows.

Also: Try a different cable.
A cheap cable could have a charging pin layout but lack data pins connections.
9 out of 10 issues with connecting to PC and getting odd behaviours is due to a bad/wrong cable.

What are the driver links if you have? I already installed the OnePlus drivers.

I used the OnePlus cable and another cable.

Driver issues win 10
Find the excellent tutorial here on drivers.
For some reason my phone didn't show up but was able to receive commands. It was frustrating because I wanted to use the all in one XDA product but couldn't.
Even if you installed drivers they can be broken!
Do drivers from scratch per xda tutorial. Don't forget reboot!
Try different cables and usb ports! My front ones never seem to work!
Don't just try fastboot commands also try adb. Like I said mine wasn't seen properly yet it took the commands.
Unless your windows is a years old install it shouldn't require reinstall.
Factory phone reset might help.
Best of luck!

Question Phone not connecting via USB

My first Poco F3 is completely unlocked and running a custom rom, still able to connect to PC even now.
I have a second Poco F3 that I was able to originally connect to my PC to debloat, hadn't needed to connect it to a PC till now. Today was the day I could unlock it but when I connect it via USB cable, original or otherwise, no usb options appear on phone and nothing shows on PC. I can use the same cable on my first Poco F3 and everything works fine. I've tried multiple cables, reinstalling drivers, restarting phone and PC, trying a different PC, enabling debugging tools, etc.
Nothing shows in "My Computer"
Nothing shows in Device Manager
No usb options on phone (default is set to File Transfer)
Nothing shows in CMD with "adb devices"
Charging still works
Is there anything I can do to at the very least unlock the bootloader? Or is this not fixable?

long shot... check the usb C port for dirt/dust/fluff blocking connection...

Most probably u debloated an app responsable for media transfer. If u can, revert what u debloated.

Did a factory reset thinking that may have been the case, still no good.
Tried cleaning out the port and still no good either

I still think it's Windows. Please can you try putting Ubuntu (or another Linux distro) on a USB, booting from that, installing platform tools (ADB/fastboot etc) and then running ADB devices. Windows is very finiky sometimes.
Edit: when you plug in your phone to the PC do you get a notification saying charging? Or is there no notification? Also does it start charging the phone?

There is a delay before it begins charging and the charging animation plays but yes it does. But then there is no usb notification. Will try ubuntu and report back

Booting into Ubuntu, before installing platform tools the first phone that I knew worked showed up and showed up in adb devices when platform tools was used. The second still didn't show up, exactly the same as on windows

Try downloading the installed stock miui rom from the update menu in the miui update menu and re-install it on the phone

Unfortunately reinstalling latest package didn't help

Can't think of anything else to suggest. Sorry

If the usb connection continues to be nonexistent, is there any way to at least unlock the bootloader without using the Xiaomi Unlock tool on the PC?

Are you sure the USB cable you're using support transfert file?

Hmmmmm.....strange! I'm running out of ideas....try different USB ports on PC. Maybe it's a faulty USB-C port on phone after all.

do you have a type c usb-otg?
If yes then see if it is detected by the phone

Yes. Used 4 different cables, 1 of which is the cable that comes with the phone. None work on this phone but do on the first phone.

Tried different ports across 2 PCs. I'm starting to think it is a faulty port, though it worked fine a week ago.

Try to use this version of Mi FLash Tool (only for drivers) : https://xiaomiflashtool.com/download/xiaomi-flash-tool-20210226
Extract and launch the executable then drivers install

Something like this. You can plug in any usb stick and see if it is detected. Another way to check whether the port on the phone is working for data as well

I don't have anything like this but that reminded me of the usb-c to headphone adapter and that also doesn't work. Sound just plays out of the speakers.
Trying with Android Auto in the car, the car doesn't register a device connecting at all either.
Either the data transfer portion is somehow disabled on the device itself (which I would love to know how to enable it again if that's the case) or it's a damaged usb port. Just strange that it worked a week ago.
Something I forgot to mention, when I went to unlock the bootloader yesterday the phone did not show up anywhere except for in the ADBFastbootTools to debloat the software as a OnePlus device but then never showed up again.

I have the same problem, did you solve it ? I replaced the usb board of the phone, still not working.

I need Hardware ids for Redmi Note 5 Pro in fastboot mode when the Android Bootloader Interface driver is loaded

To provide you with some context, I messed up a custom ROM install on my Redmi Note 5 Pro/Whyred Global version/ where the phone starts up and get stuck on the Orangefox Recover logo screen.
I thought I could just reinstall Orangefox via fastboot and format the phone to start fresh but the phone is refusing to be recognized by Windows in fastboot. It's the same Windows 10 PC that I used to unlock the bootloader on this phone and flash a custom recovery a year ago, and now it refuses to recognize my phone altogether.
Its giving me the USB Device Descriptor Request Failed error.
The drivers are not the issue here on my PC, I recently used this PC to unlock my Poco F3 and the procedure on that went flawlessly. But now it's refusing to recognize this phone. To rule out the little stuff, i changed cables, changed and tried different PCs, decided to use a USB 2.0 port on my PC thinking that might be the problem but still no luck.
I was planning to try this guide, but for that, I would need the hardware ids for the phone when its in fastboot mode. So if anyone has the phone, please I beg you give me the hardware Ids. I really want to fix this phone and give it another life.
Just in cast this fails, my last option would be to get the micro USB port replaced. I have gotten the USB port on this phone replaced twice as it used to cause problem when charging, so my final doubts are going to this.
My only evidence against a borked USB port is that the phone used to fast charge fine with this port. And since fast charging utilizes the data cables to negotiate with the fast charger, but I might be wrong about this.
So if anyone can help me regarding this issue, I would highly appreciate it.

That's an indication of basic USB enumeration failing.
It could be bad cable, bad port or your device has failed initializing USB.
It's not an indication of anything to do with Windows drivers (at this point).

I have also tried swapping cables, the micro USB fault might just be faulty on the phone.
