[Q] PC Not Recognizing USB as Mass Storage

I'm currently on DK28 and anytime I plug my phone into my computer via USB cord it just shows that it's charging. This is an issue since I would like to switch to EB13 and I need to be able to use Odin for the EB13 modem. I've tried uninstalling and reinstalling the Samsung drivers several times and not just on this computer, on two others that I have. I've also tried multiple usb cords and it's all the same thing. I've Googled the problem and everything I've tried has been useless to me, including the PDANet thing. So my question is is there any other way for me to be able to update to an EB13 rom without having to connect via USB? Or does anyone have any other ideas as to how I can fix this? I've been just using a microSD card adapter to put things on my SD for awhile now so that's never been a problem but I can't use Odin unless my computer recognizes my phone I guess.
HELP!!

Have you gone into settings, applications, development and unchecked USB Debugging?
I also have read numerous times where people have found the USB connector on the phone had something bent and was preventing a full good connection.
Good luck

You have got to be missing something drivers can be 32 or 64 bit make sure you have the right one for your computer. Is usb debugging checked in settings/app/development. Randy Shear has alot of step by step stuff for on youtube that might help

Yeah I have USB debugging checked and my computer is 64 bit which is also what my drivers are.

Turn off anti virus and dl driver again thats what I had to do. Reboot both devices also

UN checked?? if it is checked, you can't use mass storage

Tried that too and apparently that wasn't the problem. :\

I read where one person who was having something like this was told to turn their computer off; plug in the phone to the usb and turn the computer on and it worked.
Maybe try that?

I've had this problem, got real annoying after a while. I ended up reinstalling the drivers and turning off usb debugging and it would go into mass storage. Re enabled and tried again, and it continues to work.

Thanks for trying to help guys but unfortunately neither of those things worked either.

I had this problem. I flashed a different ROM (try downloading a new ROM from the phone) then flash it after following the appropriate instructions.
The ROM I had that problem with was Nebula ROM, I fixed it by flashing Bonsai v2.0.

Well I have now tried that as well and even that didn't work. This is so ****ing annoying.

Try flashing another ROM instead of Bonsai. I hate that you're stuck, but I'd try a few more ROMs before giving it to a Sprint Store.

I had this problem as well and did everthing mentioned here as well to no avail.
Now here's what worked for me.
First, install drivers on another pc (ensure that you connect, wait for drivers to load, disconnect and reconnect your phone at least twice..sometimes a takes a couple of connects to install the drivers fully).
Next use odin to flash DK18 stock firmware. When you connect your phone..suddenly mass storage will be back again. You can then load whatever firmware you wish.
This has worked on my phone and a friend's with the same issue.

I had this happen to me on 2 different machines:
- First time: A restart fixed it
- Second time: My phone didn't like the usb ports on my work laptop's docking station. The cable would only work with the actual laptop's usb port.

USB problem

I'm running cyanogenmod 7 on my evo 4g and when I plug it into a computer it only charges and never prompts me if I want to connect as a disk drive. It used to but now it just stopped. I had a backup of my rom so I put it on my girlfriends evo and hers still connected to the pc like normal but mine will not give me the option to hook up through USB. My computer says unknown device. Any help would be great. I can provide more info if you need.

More info. It gives me code 43 in windows 7. I was able to hook it up in xp but when I tried doing anything it no longer was able to detect the phone. I did a factory reset and it still doesn't work. I'm at a complete loss. I feel the only thing left to do is revert completely back to stock losing root and starting from scratch.

perhaps try completely uninstalling the device from windows in Device Manager. Then plug it in again and let it re-install the drivers

I've tried that on two different computers with windows 7. My gfs fone reads fine with the exact same rom but mine wont.

It seems like the drivers on the phone are corrupted or something. At one point I found a forum that suggested to turn off bluetooth and a few other things. I decided to see if turning off my wifi would do anything and finally my phone showed the usb debugging notification and the mount as usb notification but it wouldn't mount so I restarted my phone and now it's back to doing nothing but charge the phone.

The only difference between the two phones is the rom then? Perhaps make a backup and flash a different rom or re-flash your current rom to see if that helps

I actually took a backup of my rom and put it on my gfs phone and hers worked. we had the exact same rom. I will try installing a different rom however and i'll let you know what happens.

Okay so I had a back up of sinister rom so I restored it and now it asks me if I want to connect as a usb device and so I do and my computer still says usb device not recognized or whatever.

Wow so I tried a backup of sinister rom that I had and suddenly it asked if i wanted to connect as a disk drive but windows was still saying usb device not recognized. I reverted all the way back to stock losing root privileges and it still doesn't work. It appears to me that it is a hardware problem. I don't know what else to do.

ok, so I hooked my phone up to a computer with ubuntu on it and my phone showed up but then when I went to explore the sd card it said permission denied. Then I hooked it up in windows 7 and it showed unknown device under universal serial bus controllers(as usual) but it also had it under modem, which is what I want.

Okay, got it working on this computer. After plugging the phone in several times it still said device not recognized. I have also been pushing ##data# and it was saying the same thing. I decided to shut my phone off one last time and when I hooked it up i pushed ##diag# and now it works. ****ing stupid. Glad it's working now.
UPDATE: Now all of the drivers install when I plug the phone in except the HTC DIAG doesn't appear even when i enter diag mode on the phone. this is the only driver i need installed but i can't install it because the computer isn't picking up that part of the device....This is getting irritating.

Turns out my port is ****ed up. I'm gonna have to order a new one and replace it.

[Q] USB Problems

Hey guys,
Now, my Galaxy Note 2 was rooted. When I connected it with the USB cable to my PC the PC didn't recognize it (it used too, but then suddenly it stopped connecting). It still charges but no new device is detected. No Kies, no MTP, no Odin.
I didn't worry too much, because being rooted I could still do everything using the external sd card.
However then the ROM for Android 4.3 was leaked I stupidly installed the stock version. So, no root, and no capability to mess around with the phone.. I also have no viewable option in Settings to set the device connection to MTP, or PTP mode as usual, but maybe that's because of Android 4.3
I have bought a new USB flex part, opened it and replaced it but it still didn't work.
I download a version of phoneutils.apk and installed (because the one on Android 4.3 didn't have Qualcomm USB settings option) and choose the correct options, but still nothing.
Do you have any idea what may have gone wrong? Or what I can try to do?
I desperately want to root the thing.
Thank you very much! I appreciate any suggestion and reply.

Hi!
This might sound stupid but... have you tried a different USB cable? Or USB port? Sometimes this can solve these kind of issues. Take a look in your computer's Device Manager and see if you have any problems with the USB hub driver. Also try to connect using a different PC and see if that works.
You can try and boot in Download mode (Vol down + Home + Power) and see if ODIN sees the phone. If so, you can flash another stock firmware and see if your USB works then.

Yea tried all that! No success. /:
Phone goes into download mode but Odin does not recognize it..

[Q] usb/debugging not found

I've been running CyanogenMod 10.2 on my rooted HTC One for a good long while now. Since the ROM worked so well, I never had the need to connect the phone to a computer via USB in quite some time. A few months ago, when I attempted to transfer some photos, I ran into a weird and frustrating road block; my phone is simply not being recognized by any computer <see here>
I have updated all drivers
I have enabled debugging in Developer Options
I have tried rebooting Fastboot in bootloader
I have tried using the toolkits
I have tried everything I think I know
The weird part is that the phone charges via USB connected to the computer.
Since it didn't effect much, I just figured it was a glitch and I never ran into a problem again--that is, until today. I hadn't used my MHL adapter with the HTC One (only my GNexus), but after reviewing an intended installation of a Pioneer Appradio, I wanted to ensure that my One would work with the MHL. Hooking up my One to the Samsung MHL adapter (and power supply of course), I get no display on my television.
I am now beginning to wonder if the USB port is damaged. Visual inspection doesn't reveal anything, but I am curious if anyone has had this problem and would appreciate any help. Is there any way to test if I've fouled up the port?

Does the phone recognize that it is connected to a pc? Can you access the phones storage from your pc?

No and no

I installed Flashify and did install CWM 6.0.4.7 to see if it would help, but to no avail

Have you tried adb with a different rom or stock via ruu? If it still dosent work then, either your usb port or your cable is messed up.

I have tried adb, but the device never is recognized.
I'm currenty transferring my TWRP backup via WiFi.
I planned on switching to CM11 and see if I can't get it to work after that.

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?

Nope

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.

I honestly don't know if any of my cables are usb-otg, how would I check?

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.
