I was attempting to flash my phone with a custom ROM and only got as far as booting in recovery mode. when I selected 'Apply SDCARD:update.zip' for ClockworkMod I got a message saying that file verification had failed, so I rebooted the device.
Now though, I cannot access the device over USB and the USB settings option (Settings -> About Phone -> USB Settings) is no longer present in the device!
I've rebooted the phone but it makes no difference. I get the audible alert when I connect the cable, but nothing on the device or my computer.
Has anyone seen this before and knows how to resolve it?
Thanks

Hello all,
A bit strange problem. I was trying to adapt MoDaCo custom rom to my Vega from 1,09 FW. Everything was ok until ticking the USB debug mode. Until that time, the device was normal APX mode, but as I switched to USB debug mode, my PC (with Win7 x64) reconized it as "NVidia Tegra 2 USB Device" under disk drivers. So, I cannot go further steps, since windows doesn't recognise device as "android phone"
Anyway, to overcome this I tried to uninstall-reinstall but it didn't work. After every re-install, win7 recognised as same. No change.
Then I tried to change the drivers to right one but this was not possible since when I attempted to do so, the msg I got "You have already the most updated driver"... Then close.
Finally I tried to erase some "tegra2" entries from regedit. Some I could, some not but this was also dead end. Everytime the tabled was recognised as "usb device"
The important thing is I cannot go back to "APX mode" again.
Any advises about this issue?
Many thanks in advance.
The usb switcher is currently not compatible with v1.09. You can try going to software tool in settings and selecting "erase all content and settings"
I'm not sure when this problem first appeared. For whatever reason, my phone doesn't show up at all when connected to either of my two PCs. It must have when I first rooted the phone (to load ChainSU) but I'm not sure if the problem is recent or occurred immediately thereafter.
USB debugging is disabled. When I plug my phone into a computer, it attempts to install the MTP Driver and fails. When I uninstall my device, it disappears and I'm unable to manually install the driver's I've downloaded from other threads. When I load into the Bootloader, my device is recognized by Fastboot.
I'm hesitant to factory reset as this will leave me unable to root if the problem persists, which is important to me as I can get rid of the yellow tint on this screen.
Any thoughts?

Are you definitely sure usb debugging is disabled? The phone should install as a portable device on your pc. Also ensure to enter your password onto your phone when connected otherwise the phone will not show up its contents.
Make sure for windows media player to be updated to the latest, for the windows mtp driver.

There are a few things you can try. Have you tried uninstalling the drivers completely then reinstalling from the toolkit? In the past, I've had issues where the phone wouldn't be accessible in some way on one computer but would be fine on another, so maybe try a different computer to try to narrow down the problem as to whether it's an issue with the phone or the computer? Also, this may sound a bit ridiculous, but simply switching USB cables and / or ports has fixed detection issues for me in the past as well--something to consider.

Remove any existing drivers (while phone is connected), do the same for other android devices if you have any, then reboot and install Universal Naked Drivers. Have always had success with this driver pack.

100% sure on both counts.
I have this same issue with my rooted nexus 4, I've tried 3 different computers and several cables and it never connects to the PC and only charges the phone. It doesn't even give me option to choose media files.
I've had this issue before, my Nexus/Computer was acting in complete stupidity. When connecting the phone to your computer you will see a notification saying "Connected as a media device" on your phone, just touch it, and change it to "Camera (PTP)". It might access the camera for you, but It actually accessed the storage for me.

Thats not the problem, it doesn't give any option. It doesn't show up on the computer at all and only charges. It's the same for every computer.

I'm thinking we've screwed something up with the phone's side of the MTP protocol - mine is totally independent of the cord/computer used. All the correct drivers installed.
Have you tried Factory Resetting? I'm really hoping this is a workable option.
If you have a recovery back up the current Rom and flash stock and see if it's working

if the phone is locked with a pin/password/pattern unlock it.
I had same problem on my pc yesterday. Even if the drivers installer showed up that installation was successful, somehow for a mtp mode system was using some other Microsoft driver. Correct one was only used in ptp mode. So when I connected n4 in mtp mode storage wasn't available, when I switched to ptp mode everything was fine. Turn on your usb debug, switch on mtp and connect. Go to device manager in system, find your nexus there and rmb on it and manually reinstall driver. After this my n4 is visible in system in mtp mode again.

The problem is that even if I switch between MTP and PTP it still does nothing, I have tried multiple cables, computers and have reflashed the ROM and wiped the device but it still does not connect with the PC. This is frustrating.

Is yours able to connect during Bootloader/Recovery? Fastboot/ADB have no trouble recognizing my device.
It's really odd that if these things work, meaning your USB connection is fine, replacing the all of software fixed nothing... unless MTP occurs at a much lower level of the OS (maybe kernel is corrupted?)
I've got a similar problem that others have posted - PCs not detecting my N4. I got it last Friday (2/1) from Google and after the registering process and updating to 4.2.1, I connected it to my Win7 laptop and it showed on the PC as a drive. But since I couldn't copy/paste Office docs to that drive and had to do that through Dropbox, I didn't bother trying to reconnect until Monday, at which time the PC didn't detect it. Neither will one other Win7 nor two XP (both with WMP10) PCs. Have tried multiple cables, all of which work with other Android devices (pre 3.0). I've seen several suggestions on this and other threads, but one major issue I'm having is that some of the fixes require enabling USB Debugging. For the life of me I can't find that option in the N4's Settings. Unlike my other phones, there is no Applications subcategory under Settings on my N4 (4.2.1, Build JOP40D). Can anyone help me find that option? TIA.
Edit - Found answer. Click on Build in About Phone setting 7 times. That activated Developer options. Now to try the fixes which require USB Debugging mode turned on.
Hey all,
I have tried to google and figure this out but my phone doesn't show up in device manager in windows or in android file transfer on mac EXCEPT when in download mode or when the phone is off/charging via my computers USB port.
So when in download mode, the phone shows up in device manager....
When my device is off and charging via USB port, it shows up in device manager...
I have tried USB debugging mode no change...
Charges just fine. No usb port issues because it connects during download mode etc...
During these times, i obviously can't access the SDcard.... but as soon as the device boots, it disconnects and disappears from device manager even though its still charging etc...
This only happened after the last OTA update.
I assume i will have to restore to defaults as its probably an issue with the kernel and usb protocol but I dont have the phone rooted and i don't want to root it at this time... I am hoping there might be a quick fix and/or setting i am missing.
Thanks!

You do have to have USB debugging mode checked. If you don't have the developer option enabled in settings, go to about phone, find your build number and tap on it rapidly until it says your developer option is enabled. Back out and you should see a developer tab. Click it and make sure USB debugging is checked. If that doesn't work you might reinstall the latest USB drivers.
i did both of those. the odd part is when in download mode windows chimes that my device it attached.. no problems right? but anytime the android OS is running no chimes at all no recognition at all on any computer... its almost like back in my linux days when the kernal had a usb module failed to load... i swear its as if the kernal turned off usb data communication... power is fine... just wont communicate unless in download mode or in a power off state.... totally weird...
When you plug it into the computer, pull down your notification drawer, make sure USB setting is set to MTP. It usually is set to installer, or charge only by default.
Also I'd say completely wipe out your phone drivers on the computer, and reinstall all new ones.
Possibly reinstall ADB as well.

Hi,
Redmi 3s, MIUI 8 Global 6.11.3
bootloader unlocked, rooted, TWRP recovery
developer options - USB configuration - MTP selected
now, every time I connect my phone to (any) PC by USB, a notification pops up "USB charging only" for a few seconds. If I catch it, tap it, and select MTP, everything works as planned.
when I toggle the USB configuration in developer options between charging only and MTP, the next time I USB connect the phone, it will connect in MTP mode. But only once. Unplug the USB, replug, and I am back at the "USB charging only" popup. MTP is still selected in developer options.
Obviously, I must be missing some related setting to make, or this issue would affect a lot more users.... Does anybody have an idea how to make MTP the permanent default when connecting USB?
thanks
tdklaus
I'm facing the same issue!
May be, any Xposed Mod fix it, anybody know?

The issue persists after switching to xiaomi.eu 8.0.10 stable. Now the "USB charging only" at least stays in the list of notifications and can be tapped there even if I miss it in the first few seconds. Still annoying, though....
