[Q] Nexus4 wont show up connected to a computer.

When I plug in my nexus4 to a computer it wont show up...most of the time.
I've used 3 different cables.
4 different computers, running, linux mint, win7 and XP.
I installed clocwork mod recovery today and then it showed up as a new device on a XP copmuter but then it would never show up again.
I'm rooted, running carbon ROM, usually with TWRP recovery but switched today.
I've tried it in MTP and PTP modes, debugging on and off.
it charges just fine from a PC.
any ideas are appreciated.

Have you installed the drivers properly?

For some of the computers. Today I'm at work and I don't have the drivers installed. I keep my phone plugged in to charge. In the past the PC, running windows XP, always pops up the new device found notification. It won't even do that except for the 1 time mentioned earlier.
it it possible for the recovery image to affect things?

Mine won't show up in my PC (windows 8) If USB debugging is off. I'm fairy certain this behavior started at some point during the rooting process because I had a hell of a time getting the files to the phone.

From what I noticed, when you use a lockscreen with some kind of protection the device memory will not show up if it hasnt't been unlocked in the past few minutes or before connected. This is mostly for security reasons to make sure you are the one accesing the device..
I am not sure if this is the source of the problem you are mentioning but just to let you know

That's not it, I'm doing this with it right in front of me, unlocked

Have your nexus connected and disable developer settings and delete your adb driver. Then select mtp mode while connected and you should be able to connect now.

FWIW, I have encountered odd connection issues with my Nexus 4 running bone-stock Android.
As I recall, it won't connect to ADB in MTP mode. In PTP mode, it usually works. Personally, I just said "screw it" and starting using MyPhoneExplorer for everything.

Enable USB debugging in your phone. Nuff said.

nothing works, PTP, debugging on/off, etc.

well I finally got a hold of my wife N4, it connects just fine. so I think it's definitely a hardware issue.
Ifixit shows how to replace the daughter board.....but I'd rather send it to LG for warranty replacement but I have it rooted.
If I could just get it to connect once more I would flash it back to stock.

[Q] Computer no longer recognizes Nexus on USB

For some reason, I can no longer get any computer to recognize my Nexus 4 when connected by USB. I can charge but cannot get the phone recognized.
A couple weeks ago, everything was working fine. I was running Cataclysm (November build based on 4.3). I upgraded to the Nexus 5 and decided to give the Nexus 4 to my daughter. I was able to connect the Nexus 4 to the computer and move all my photos and music etc off of the phone. After moving my files off and doing a Titanium backup and Nandroid just in case, I did a complete wipe on CMW (6.0.3.5). Everything fired up fine and I had no reason at the time to test the USB.
However, last week, my daughter was complaining about bad battery life and I decided to take a look and go ahead and update the phone to the latest (Dec. 12) Cataclysm build based on 4.4.2. Before flashing the new build, I connected the phone to the computer by USB but could not get the computer to recognize the phone. The phone charges, but is not recognized in device manager and does not connect.
I've done everything I can think of to troubleshoot the issue - all without luck - including:
Turned USB debugging on and off. No luck.
Changed the USB storage mode from MTP to PTP and back. No luck.
Confirmed fast charging isn't somehow enabled. It isn't.
Tried several different USB cables. No luck.
Tried a different Nexus 4 and my Nexus 5 on the same computer. They work.
Tried the subject phone on a different computer running Windows. No luck.
Tried the subject phone on a computer running Mac OS. No luck.
I did go ahead and flash the latest Cataclsym build (I did a full wipe again) but sill no change. I don't see any evidence of physical damage to the micro USB port but I took a small toothrush and gently cleaned the contacts with rubbing alcohol.
At this point, I believe the problem is either the a) the port is bad or b) somehow, the phone software/ROM is screwed up.
Is there any way to determine whether the physical port is bad? Any other ideas. I'm kind of at the end of my capability here.

can adb recognize it?

adb devices

I don't think so. I'll have to check tonight when I get home. I tried to get Wug's toolkit to recognize the phone with no luck but haven't tried that command on its own.

No luck. I attached the Nexus 4 to the computer, entered a command prompt to navigate to the platform tools director that has the adb files and entered the "adb devices" command. The response was "List of devices attached" with no phone (or anything else) listed.

I have that issue too. I´m on windows 8 and to root and being able to recognize by the pc I changed it to PTP. It only works in PTP and I have to pass all the data to the camera folder to send info

I don't think I've got the same issue. I cannot get any computer to recognize the phone under any mode (storage, photo, debugging on, debugging off). Nada. At this point, I'm pretty sure it's the port gone bad. I just wiped the phone again and clean flashed the stock 4.4.2 ROM, radio and bootloader. Still no connection.
Argh.

can you try going to recovery, then type adb devices?

I had this problem and i found away to fix it. Plugin your phone to a computer. Start > right click on my computer > properties > device manager. Look for Samsung > expanded it you will find Nexus 4. Right click on it and choose uninstall and check uninstall driver. Unplug your phone and restart the computer. Re-plug the phone and wait for the drivers to install.

[Q] Nexus 4 won't connect to PC

Hi, I can't get my computer, Lenovo y410p running Windows 8.1 to recognize my Nexus 4 in the file explorer. The Nexus Root Toolkit also will say "no fastboot device connected" when it is plugged in via USB port. However,
Stock Nexus 4
4.4.2
Kernel 3.4
Build number kot49h
Computer won’t recognize phone in file explorer.
Enabling USB debugging has no effect.
Enabling and disabling MTP has no effect either.
However, when I am connected in MTP mode my comp recognizes the phone in the “safely remove hardware and eject media” in the notification area of the taskbar.
I can connect in Camera (PTP) mode – my computer will show my phone in the file explorer.
I’m using a Lenovo y410p running windows 8.1
I’ve used the Nexus root toolkit to uninstall and reinstall the drivers and this hasn’t fixed the problem.
I’ve also used the device manager to uninstall all drivers and this hasn’t fixed the problem.
I’ve tried 3 different USB cables – this hasn’t fixed the problem.
I don’t have a fast charge app installed.
I want to root the phone so that I can use Button Remapper to assign one of my volume buttons to be my power button. My power button is currently broken, forcing me to use Awesome On to turn my phone’s screen on and off. I’d also like to be able to load music on to my phone.
If anybody has any idea wtf is wrong with my phone I’d love for some help. Thanks.

Is your phone in bootloader mode when the pop-up says "No fastboot device connected"?

No, at the moment its in fastboot mode. (secure state enabled, and lock state - locked)

Does the driver state "adb interface" under device manager?
Did you also try the command "fastboot devices" on command prompt?

i just did a factory reset and my comp still won't recognize my phone in MTP mode with USB debugging enabled or disabled. However, when I connect in camera PTP mode, my computer will recognize my phone when debugging is enabled, but will not recognize it when it is disabled.

Sounds like you are missing the CORRECT USB drivers, (note the windows ones don't always work) try PDAnet for an easy installation of them, then check ADB drivers, as said above the command "fastboit devices" is a good guide to your connection.

Nexus 10 Recovery - USB not enabled

Hi,
When entering recovery mode on the Nexus 10 (Android 4.4.3), when I connect the tablet up the a computer it does not detect a USB device. This is not the usual driver related issue - nothing shows up in device manager - it is as though the USB cable isn't even connected. The usual sound from Windows when you connect a device does not sound.
I can connect fine when the Nexus 10 is booted, and I can call "adb reboot recovery" and the tablet reboots to recovery, but then there is no USB connection.
To reiterate - there are no driver issues as I'm not even getting as far as loading a driver! I've tried two different computers (Windows 8.1 and Windows 7) and two different USB cables.
Anyone seen this before? Why is USB disabled when in recovery?
Thanks,
Gary.

I was unaware that the stock recovery had adb..
Let me look into this..
Thx Josh

Figured this out thanks - turns out "adb reboot recovery" doesn't put the device into a state of waiting for a sideload - you have to do a further press of POWER+VolUp to bring up the menu then select sideload via ADB - the USB then kicks in! Doh.

Nexus Player not showing in Device manager after Flashing Marshmallow!!

I Flashed the latest version of android 6.0 from the google's factory images website, and now want to root my NP.
However, I'm don't see the device in the device manager anymore (I've enabled usb debugging).
"adb devices" returns nothing neither on my mac or windows laptop.
Please help!!!!

OK, got it sorted out
so I left the NP connected to my windows laptop, and played around with the usb debugging,
turned it on and off for 3-4 times and suddenly my laptop recognized it and I started seeing it in the device manager.
but "adb devices" was still returning nothing!!!
so unplugged the usb cable plugged it back in, and suddenly I got the message on my NP to trust the device that was connected to it
after I checked that, now I "adb devices" returns my device.

If you have any issues with Computer not detecting Nexus Player it is the driver. Very easy to sort. Keep the drivers in a safe place and just reinstall by doing driver update and point towards it manually. This worked for me on all roms without any issues.
