[Q] PLEASE HELP!!! Cannot connect to computer!!! - Nexus 4 Q&A, Help & Troubleshooting

Hey everyone, thanks in advance for the help. I just got a nexus 4 yesterday, that was already updated to 4.3 when I got it. My problem is when I go to unlock the boot loader, it won't recognize the phone. It says "list of devices attached" but doesn't give a serial number. Also, before this, it was giving a serial number, but was saying it was offline. So I uninstalled and reinstalled the drivers. Any help is most appreciated.

You might need updated adb/fastboot exe/dll's. Grab them from a toolkit, that's what I did.

I completely upgraded the whole SDK. Still no good.

Try this... When you're connected to the PC , toggle USB debugging off and on.. It might ask for authorisation of ur PC in your phone.. Give yes.. Then do adb devices .. You might fight the offline thing gone

I did that, got it to boot into boot loader through adb, then my fastboot drivers wouldn't install. So I uninstalled everything and started from scratch and now I can't even get the serial number to come up.

Hmm.. doesn't it get shown as Android devices under device manager?
I too had a similar kind of problem with adb. I uninstalled the drivers manually and installed it again using Koush's Universal ADB (Android Debug Bridge) Driver for Windows. It has fastboot thing also. It worked for me.

You can also try someone else's PC or something. Install the drivers using the above link and just fastboot. Sorry, if that is of not much help. I'm new, both to this place and to this Nexus 4 device as well. All the best.

[Q]Computer won't recognize phone?

When I plug my wife's phone into my computer it doesn't recognize it as a media device. It does recognize it as an adb device though so I was able to unlock the bootloader and root it. She wants me transfer music and can't, any ideas? Also when I plug in my nexus 4 it appears as a media device.

when you first put it in, did it download any drivers? if it didnt then go to lgs website and download them.
I got the same effing problem and haven't been able to figure out how to fix it. Every time I uninstall the phones drivers stupid windows will install it right back as adb device...

I have a similar problem with my wife's N4. Hers does not recognize as a MTP device nor as an ADB device. In device manager it shows it, but adb devices never lists it and it never shows up in Computer when I disable USB debugging. My N4 has no problems with either. I've uninstalled and reinstalled the drivers and can't figure it out!
Weird thing though, it detects it in fastboot mode.
I just got off the phone with Google Play Devices support and explained the issue. They are assisting in getting an exchange.

I had this same problem, and it was the lack of drivers. Uninstall in device manager what you have, restart, then install the 4.2 Google SDK drivers. This works in Windows 8 without any extra procedures. I have the SDK installed, and directed the 'have disk' driver search to the SDK directory/extras/google. There were three adb drivers, and I installed them all. I really don't know what I'm doing, but that solved the problem.

Dude it's not the phone lol. It's the computer. When I plug my phone into my dad's computer it detects it fine. It happened on mine because I installed those adb drivers

What worked for me was uninstalling my old Motorola drivers and then using http://forum.xda-developers.com/showthread.php?t=1995688 to uninstall the SDK drivers for the Nexus 4 that I had originally installed when I got the phone. Then I installed the drivers provided with the Nexus 4 Toolkit and everything works great. MTP, ADB, Fastboot, and the phone is recognized within CWM/TWRP.

I can uninstall the drivers just fine but when I plug in the nexus it automatically installs the adb drivers again..

have kind of a similar problem, but a bit different
my computer was able to detect the phone in mtp, adb and fastboot mode, installed the drivers, unlocked bootloader, and everything was fine
this morning the computer no longer able to detect the phone, but it still charges when i plug in the usb cable to the computer; cant transfer files, adb and fastboot list no devices, even device manager doesnt show the phone being plugged in
UPDATE: just tried on another computer, nothing... not even asking for drivers, and the phone doesnt even show it is connected in MTP mode like before... im screwed
I have a similar problem too..
My Nexus 4 works fine when I plug it into the computer, it shows the device just fine. But, when I plug my brother's Nexus 4 into my computer, it does not recognize it, it installed the drivers but I can't see the device in My Computer. In device manager, it shows up. With my brother's phone, I can mount it as Camera (PTP) and I can go into it, but it cannot detect it as a Media device (MTP)

Perhaps, in device manager, select the adb driver, right click to update, direct the update to have disk....SDK Google extras location?

In my case anyway, its definitely not the computer. I have two identical, brand new Nexus 4 16GB phones. One is recognized with the appropriate drivers on my computer and the other is as well, however the second one does not show in My Computer nor get listed with ADB devices - unlike the first. The only difference between the two scenarios is the physical phone that is plugged into the computer.
Same with me, my phone works fine but when I plug my wife's in.. Nothing.

I haven't been able to fix it by the suggested methods.. When it's on the other mode for camera pics it works fine and in device manager I get under " portable device" nexus 4 showing up.. But when I switch it to MTP all I get is android adb interface in device manager and no nexus 4

Need some help installing drivers

So I got my n4 last week and I've been trying to unlock and root it to no avail. I've tried using the toolkit as well as using the method indicated in another thread on xda. I keep getting errors when trying to install the drivers.
I've been able to get the adb driver installed on win 7, but not the fastboot driver (using the toolkit).
I've even tried installing the drivers using the toolkit on a VM running xp without any luck.
Could someone please help me out with this? I remember having similar issues when rouoting my captivate, but I was able to use my work laptop to install the drivers (I don't have admin rights anymore).

A) Proofread.
B) Reboot into recovery and plug the phone into the computer. Go to device manager on your computer, look for the USB device with the yellow exclamation point, update the driver. Reboot your computer.

A) Wow that was bad, corrected
B) No devices were displayed in device manager when I booted to recovery. By the way, when I tried to update the drivers in fastboot mode, I kept getting errors.
Perhaps an earlier driver needs uninstalled? Check this thread: http://forum.xda-developers.com/showthread.php?t=1992345
I tried that driver, that is the driver I referenced in the OP, sorry for boy linking.

Trouble with adb can't find device

I'm newbie, I accidently formatted everything. My nexus 4 now has no OS, and I don't have rom inside my phone. I watched many video how SDK and adb to sideload rom to the phone, but it keep saying the device is not found. I even went to buy USB flash adapter to plugged phone but it can't read zip file. Please help.
I think device drivers are not properly installed in your PC.. Follow efrant's guide for installing the drivers and flashing the device

[Q] Fastboot Doesn't Work

I'm not able to use fastboot at all on my nexus 4
I always get:
< waiting for device >
adb works fine, I can shell and view all the files etc. and "adb devices" lists my phone there and doesn't say offline. I've done all the normal stuff like changing USB ports (2.0 and 3.0) and I've tried different versions of ADB and the driver, clearing the RSA keys on the device. The phone is totally stock, no root and running 4.3 / JWR66Y and this has been happening before the latest OTA (JWR66Y) update (first OTA of 4.3)
Here's my bootloader info
Command line: console=ttyHSL0,115200,n8 androidboot.hardware=mako lpj=67677 uart
_console=enable lcd_maker_id=primary lge.hreset=off lge.reset=mode_reset gpt=ena
ble lge.kcal=0|0|0|x lge.rev=rev_10 androidboot.emmc=true androidboot.serialno=0
0475fbe14129674 androidboot.bootloader=MAKOZ20i androidboot.baseband=mdm bootrea
son=reboot
and I'm currently using the "Android Composite ADB Interface" Rev8 driver from the SDK on Windows 7 x64 along with the 18.0.1 version of the platform tools.
Did you download the fastboot.zip and place it in platform-tools of the android SDK?
Sent from my Nexus 4
Try the SDK package ..

I'm using the fastboot binary from the SDK as stated in the OP
I know this may seem obvious but covering the basics. You installed the fastboot driver? Is phone seen at all via device manager?

Do you mean the ADB driver or something else, I've tried the naked ADB driver and the SDK ADB driver, both give the same result, ADB.exe connects, I can open a shell and see the files etc., but fastboot.exe just hangs on waiting for device
When you plug in phone and its in fastboot is it recognized by device manager? Do you see an exclamation point next to it. If so you have to click and choose update driver(I used sdks version)

No problem there. I don't think ADB would work if the driver weren't working would it?
It would still work. Technically the driver is installed twice even though its the same. Once while phone is booted up and once while in bootloader.
Have you tried reinstalling the driver? after updating to 4.3 I had issues with adb and fast boot. I had to reinstall the drivers and all went back to normal

Yes I've reinstalled the driver a few times and tried different drivers. I've tried the universal naked 0.72.the rev8 from the SDK and Koushes, all 3 work with adb and none worked with fastboot

Which driver did you use in the end? I've tried just about everything, I even grabbed another nexus 4 and I'm having the same issue with that one (which is on the earlier 4.3 OTA update btw)
Download the fastboot.zip and place it inside platform tools, even though SDK shows fastboot download fastboot again and place it inside

Download from where? Which files do you suspect are missing?
I used the one from the SDK. When booted up device manager shows adb composite and when in boot loader device manager shows android boot loader interface.
When you are reinstalling the drivers did you uninstall them first. That's what I usually do. Once helped someone who had the driver installed several times, so they were conflicting . I would uninstall drivers and delete any mention of them. Reboot PC. When plug in phone I ignore it trying to search and install boot loader driver. And install it manually

Do you have basic knowledge of ADB and fastboot? If yes, you can download factory images and then flash them in fastboot.
If you can get into the bootloader screen you can use fastboot to restore the factory image to your phone, follow the instruction in the links in my signature. There are probably youtube videos as well that can guide you through the process.

Just Google wug's nexus tool. I think it's version 1.74 or something now. Install it and follow directions. I forget if you need factory images already installed for it to work.
I got out of a similar jam earlier. You may have to flash everything thorough fastboot manually though.

Use the Universal Naked Driver in my signature, you might need to disable driver signature checking before installing it. If you can't get it to install, try the Google USB driver.
It looks like the bootloader is damaged for your device, this is your last hope at recovering it: http://forum.xda-developers.com/showthread.php?t=2347060

I try to use many unbrick methods
like the unbrick method with the download mode (can't acces to download mode)
the unbrick method with the fastboot (can't acces to fastboot)
tried the unbrick method with Nexus root Toolkit (in the mode softbricked/bootloop) but doesnt work need fastboot (can't enter in fastboot)
Can't use ADB !!
determinated all unbrick methods need fastboot, download mode, adb or something but NOTHING WORKS !!!
just the unique thing is my computer detect as QHUSB_DLOAD (qualcom driver or something like that) apparently is using the port COM5 but not sure :crying:
Any ideas would be appreciated or any tut :crying::crying: im desesperated and now hate a lot my EXgf yes now is EX !!!
I've already post above the link to restore your device using download mode, try it. Try using a different PC to get the device detected.
I think you should sort your personal life first if you break up with someone due to a careless mistake on a relatively cheap device.
