When I turn my n7 on all I get is the android with the red triangle over it and underneath it says no command. I'm unable to do anything with it. When I press power & volume up all it does is dim the screen/undim it.
From what I've been reading, I think I need to load a recovery image, but when I try to load it, I'll either get a DLL error, or in command prompt it'll give me an error saying the image can't be loaded.
The DLL error is something like adbwin.dll & its frustrating because its in the sdk\tools folder, I can see it & I've tried setting environmental variables in control panel/system to the DLL path & I still can't get my system to see it. Any help would be appreciated.
I'm using windows 8 and the recovery image I tried was twrp 2.2.1. I'm missing a step somewhere I'm thinking.
No suggestions? Uggghhhh
Is there anyway to install drivers without enabling USB debugging?
Look up Wugfresh's Nexus Root Tool Kit.
Once you install all of the drivers it'll be a breeze....

Tried this already too just last night. I've tried using samsungs mobile phone drivers, asus', and the naked drivers. I can't get this thing to be recognized. its not even charging when plugged in to my PC. I've also tried it on a w8 PC & win 7 PC.
That's an entirely different issue then. Try a different cable?

Tried a few. The original stock cable, a cable from my cell phone & a diffferent phone. I also tried different USB ports lol. I've tried everything I can think of. Thanks for the suggestions though. Open to more.

Have you tried to do something simple at the error screen with fastboot? For instance just do a fastboot devices? Does it return anything? Have you properly configured your PC to run adb and fastboot? Are you trying to run fastboot/adb from the directory all the files are stored in? I know this may be basic stuff to some, not sure of your level of skill, but even still professionals still can overlook something.
Here is the latest Android Composite ADB Interface Driver straight from SDK.

If you can get into bootloader then you can erase your existing partitons then flash all the images from the Nexus Factory Images package to restore your device to stock.

I tried running cmd to check for fast boot devices but nothing came up. Tried root kit to detect & nothing is detected either. All my files are located in C:\ which is where I had fast boot pointed to.
I'd say I'm pretty noob at this. It was originally rooted & no orobs till this instant. I'm pretty positive adb/fast boot is installed correctly.

USB debugging is not needed to use Fastboot.
Have you tried power and down? That's how you get into recovery. I just reread the first post and you stated that you're pushing power and up volume.

I have a Google Nexus 4, bought direct from Google, I rooted it and it was working well for a while. Then the battery started draining super fast. A friend recommended resetting, so I did and it seemed to fix it for a while. Then the battery issue came up again, so I reset again, expecting the same outcome....however, I wiped the phone completely. It turns on and displays Google, and that's it.. My computer does not recognize the phone when I plug it in, and I cannot get the USB Debugging to even be an option. Every resolution I have found for this situation needs me to enable the USB Debugging mode. Is there any other way to get all the OS files back on this phone or is it bricked?
When I plug it into the PC it tells me to look up drivers, and this is how it sees my phone: Unidentified Device USB\VID_0CF3&PID_3000&REV_0200.
It isn't recognized as a phone at all. It tells me to download Atheros Drivers.
I have searched for days trying to find the solution to this. Any help would be so very appreciated by this noob
Did you try to manually delete drivers from the device manager? Ticking the option that permanently delete the driver from PC.
And after doing this...trying Windows Update for driver installation?
PS: also try to manually flash with Fastboot all the latest Factory Image from Google....

Yes, I've done that, there are currently no drivers on my PC. When the phone is plugged into the PC, it tells me to find drivers because it is an unrecognized device.

Hold volume up/down and power until it reboots into boot loader mode. Download the factory images from the Google website (search nexus stock images on Google) and plug your phone into the computer and use fastboot to flash the OS back.
Rember, as long as you can get the phone to turn on you can fix whatever other issue your having providing its software related.
To fastboot flash,
You need the android SDK, use Google to figure out how to install it but its not hard.
Run the flash-all bat found in the archive file you downloaded, or manullay flash each partition like this.

Download the toolkit and install the drivers
Sent from my Nexus 4 @1.944 GHz on Stock 4.2.2
yea download Google Nexus 4 ToolKit install drivers then you can factory restore using the toolkit to restore
i think i chose option 9 and it downloaded the need restore image
Tried it all
I have tried all those ideas and all have failed. I can never get the computer to see my device. All it says is unknown device. When I click update drivers and direct it to the sdk driver I download it still gives me no connection through fastboot or adb. I have tried selecting various general Android drivers through the update drivers screen, Found some from Google Inc. that specify Nexus 4 bootloader interface and adb interface. Nothing is working. I think I need to have a working Nexus 4 to install to correct drivers first and then I might be able to piggy back off those and use my phone to flash through fastboot or push adb. I have worked with both command lines with reasonable success before rooting samsung tablets and phones and htc's. I am familiar with the process and have read numerous ideas none of which seem to work in this case. Made it all the way to Google search page 12. Anyone know a way to force install the Nexus 4 drivers without having a working phone present? I am thinking I just need to go buy a new one and return it after I plug it in to install drivers. Don't want to have to pay the re-stock fee though. Any other ideas are very welcome.
And I have tried to use the toolkit as well and it does nothing either. I have the stock rom ready to go just need a way to get it onto the phone.
I took the OTA to 4.3 on my Nexus 7. It was previously unlocked and rooted, but had no kernels, etc changed. After the update ran, I lost root as expected, however, in trying to get it back, I've discovered I'm having a couple of other issues.
First, the device is no longer working properly via USB on my PCs. On both my Win 7 and Win 8 PCs, the device won't properly connect to where I can browse files or anything else. On the Win 8 computer, I see a Nexus 7 device in Device manager, but drivers won't install. I downloaded the drivers from the Asus site, but trying to manually install them doesn't work on the Win 7 machine, and on the Win 8 machine, they install but don't seem to be working with the Nexus 7 as it still shows a problem in Device Manager.
The tablet also will not boot into recovery mode. I can power it up into fastboot mode, but if I select "Recovery Mode" and hit the power button, I just got the Android with the red triangle for a few minutes before it boots back into the OS. After doing some searching, I saw where you might need to have it plugged into a PC to get it to go into recovery, but that doesn't work, either (might be tied to the USB problem).
Ideas?
Did you turn on developer options, and USB debugging? Have you tried USB connection type PTP instead of MTP?
If you have the stock recovery, the red triangle and Android are normal. You can bring up a blue options menu by pressing the power and volume up buttons from the red triangle Android.

I was using the stock drivers off the Asus page. I'll look around for the two you mention. I assume they're posted on here somewhere.
And about the recovery just try flashing another recovery from fastboot

Without USB access? That's my dilemma.
OK, I'm getting closer. I got TWRP installed and rerooted it. I had to do the "Revoke USB debugging authorizations" on the Dev Options screen. Then it would work via ADB.
Still not browsing files yet on my desktop, but at least I know I'm talking to it. So now I'll play with the driver installation a bit.
EDIT: Well, drivers reinstalled for about the 4th time, and it's still not allowing me to browse files from my desktop. Galaxy S4 works fine as soon as I plug it in, even if I also uninstall it's drivers. Ideas? I obviously have it working over USB because I can give it commands and reboot it via the PC.
OK, try this one. Plug in your tablet to pc, go to hardware manager, find your Android Device then choose Uninstall (choose Remove all drivers for this device), unplug and plug in your tablet again. Your Windows should discover few new devices (mine has discovered three) and download drivers for them then you should see Android ADB Interface in Android Devices and Nexus 7 in Mobile Devices.

After you plug your nexus in have you unlocked the screen to see if it is asking you to authorize the tablet?
What other steps have you taken? Have you installed proper drivers? Have you manually chosen to update drivers with the sdk drivers if in device manager is showing the nexus? Have you tried the drivers from Asus?

I personally did all of those things. After having the Nexus "forget" all the other PC authorizations on the dev screen, I finally got it to accept ADB commands, just not to properly install drivers that would allow me to browse files like it had done on 4.2.

Try turning off usb debugging. My tablet cannot connect to pc but with usb debugging off it at least recognises tablet as a media device and this enables me to view its files
.but still the problem of not being able to root
hello,
I have recently been playing with roms and stuff on my n4. (did it on other devices, and never had any problem i couldnt fix)
but right now I kinda screwed up so bad, that I need some help.
I kinda wiped all the data on my phone from the cwm recovery.
and I'm stuck with this situation:
I can boot to bootloader + recovery
I can't boot to any rom (because there is none)
I can't connect to any pc because they won't recognize he's there (forever alone... ) (and yes i've tried all kinds of drivers)
I can't connect with adb because I can't turn on usb debugging mode.
So right now I'm stuck
I've come to the conclusion that i probably need to use fastboot fix this, but like I said before, no computer will recognize my n4. (not showing up in device manager)
also tried about 6 different usb cables - no luck
different computers ( ubuntu - mac - windows) - no luck
So is there any smart guy out there who can help me?
greetings, Julian

I apologise for potentially getting your hopes up, but I am in the exact same situation. I am very much interested in this thread.
Google 15 second adb drivers xda. You probably need to get adb and fastboot setup for the pc to recognize your device. In order to fix it you'll meet to use fastboot or adb commands

You need to delete all your driver files from your pc and start over.
There is no reason for you to not be able to connect via fastboot.
Find a clean win7 machine and start over, installing the fastboot drivers before connecting your phone.

I've tried installing the drivers but whilst the drivers claim to have installed correctly, my phone is still not recognised by my computer in Device manager. I've tried uninstalling all previous drivers before trying this.
Before we go on - should I be trying to connect my phone to the computer when turned off, in bootloader or in recovery?

Is fastboot essentially bootloader? I've tried in the initial bootloader menu and I've tried having clicked 'start' from the bootloader.
In the bootloader it tells me fastboot is enabled, btw.

When you're in the bootloader you can run fastboot commands. With your device plugged into the pc, from a command prompt opened on the same folder as fastboot.exe, run the command fastboot devices. Does fastboot return your device info? If so you're good to go running fastboot and flashing a factory image

Brief update - I think. My computer began installing the drivers again, but told me the device suddenly 'disconnected'. I think it's a hardware issue and that the port isn't seated properly. I'm going to replace the USB port and see if that helps.

Did you do a clean install?
Have you used a different USB cable? Some cables are charging-only, with no indication otherwise. Internally damaged cables can also turn into charging only cables. Ironically, I just replaced one hooked into my daughter's phone today that would only charge intermittently.
There is no reason that wiping partitions in recovery would prevent your phone from being recognized by your PC at all.
Try a clean install of the drivers on a fresh pc with a different cable.

This is typical when you connected the phone to the PC before installing the drivers. Windows will sometimes install a generic driver when you hook up the phone, preventing it from detecting the need for adb and fastboot drivers

I tried uninstalling all drivers, including in USBDeview before running 15 second drivers then trying to connect my phone in fastboot/bootloader mode, with various cables and various ports. Nothing happened!
I've bought another USB cable which should be arriving soon. I've also bought a new charging/USB port to replace that inside the phone.
If it Works with that cable please give me a headsup

Well, I had similar issues when I bought this phone (coming from a HTC one s) connecting to fastboot.
What I did was:
Delete all drivers related to adb/fastboot/android (use a software to completely clean the files).
Booted my phone into fastboot mode.
Connect to PC and wait for windows to show the new hardware dialog.
Install the correct drivers (which i had downloaded and extracted) using the dialog box.
Profit.

A brief update
I remembered I have a second Android phone knocking around. I plugged this in with one of the cables from earlier - perfect installation with all drivers, etc. This has further convinced me that the hardware of the USB port on the phone is the issue.
Thanks for all help - I'll update again if the hardware change works, or doesn't.
ok, ive installed a new windows and installed all the drivers and then i connected the phone.
Nothing.
i'm getting desperate here..
My Nexus 4 LCD cracked upon impact today and the digitizer is damaged. I want to backup my phone before I repair the LCD, currently it is:
- Rooted
- USB Debugging is enabled from settings
- Device is set as "Camera" and not "MTP"
I want to use the tool http://forum.xda-developers.com/showthread.php?t=2786395
But I cannot tick the box for USB Debugging when using the tool, so I used the following in ADB in Recovery (TWRP)
Adb shell
echo "persist.service.adb.enable=1" >>/system/build.prop
echo "persist.service.debuggable=1" >>/system/build.prop
echo "persist.sys.usb.config=mass_storage,adb" >>/system/build.prop"
reboot

However, the device doesn't show up. In device Manager (Control Panel) and while I'm in recovery I get "mako" with a yellow triangle
for which I cannot install any driver (I downloaded them through SDK).
I think it's a driver issue and I want to get sorted to have access to my phone, any ideas or experiences would be welcome!!
Thanks!
It's probably not showing up because camera is selected instead of MTP, but my question is why do you want to back it up.... just Repair Lcd and it should be just like it was before lcd broke....

I have a business repairing phones.. nothing is going to happen when you disconnect the lcd and reconnect the new lcd... But if your phone has a frame I would Repair the whole frame and lcd together... Its much easier then just repairing the lcd alone

I use either Amazon or ebay mostly Amazon because they have prime which means you get shipping free and some items you get in 2 days so if you order it on a Friday it comes on Sunday... Its free for a month and then $99 after that or you can keep making a new email every month to beat the system

Is there any other way to get to my files on the N4? or at least control the device with the cracked LCD?

Is your bootloader unlocked? If so flash twrp using fastboot. Then boot into twrp and you'll be able to copy and paste files from your device to your pc. If you can't see anything on your screen it might be a little hit and miss but it should be possible.

Yup bootloader is unlocked, I have twrp already but how do I choose the options in twrp? The screen doesn't respond! Also how do I copy files using twrp?

You don't need to choose any options (assuming you have one of the newer versions). All you have to do is boot into it. Boot into the bootloader, hit vol down twice and then power. Let it boot and plug your device into your usb cable. The device should show up on your pc.

That's the problem though, I had set it on Camera instead of MTP, so now I only get access to files like DCIM and NOT the rest of the files. Is there any way to circumvent this and have access to all the folders?

Have you tried booting into twrp? Twrp defaults to mtp mode so I don't think it matters what you set the device to.

I got into twrp, but again i had "mako" in the control panel device manager, so neither Camera nor MTP worked BUT then:
- I installed some drivers from the N4 Toolkit, namely the samsung drivers, and they worked. NOT MTP though, I am able to get into recovery and use ADB Pull commands but again for some files transfer is interrupted by "No such file or directory" that cancels the operation - so I need to somehow transfer directories/subdirectories individually..anyone can help out here?
- Other thing, though drivers are now installed correctly now, I still can't get to MTP and I think that might due to the fact that ive enabled USB Debugging. From my experience on N4 and N6 if I disable USB debugging I can use the device as MTP, if I enable it I cannot, I can only use Camera if it is enabled - so second question: can I disable USB Debugging through ADB somehow?
Thank u all!

Ok, I don't know the status of your device. I know with the latest twrp you can boot into it and access your device through mtp. Adb pull is a pita if you don't know the specific location and name of files. Here's what I'd do:
1. Google 15 second adb install xda. That'll install the usb drivers and fastboot with system variables set so you don't need to worry about the path to fastboot.exe.
2. Download the latest twrp image from here http://techerrata.com/browse/twrp2/mako. Rename it twrp for simplicity.
3. Boot into your bootloader and open a command window in the same folder as twrp.img is in.
4. Run the command
fastboot boot twrp.img
5. You'll be booted into twrp and with your device connected to your pc you should see nexus4. From there it is as easy as copying and pasting files from your device to your pc.
When booted into recovery it makes no difference if you have usb debugging checked you not

DUDE THIS WORKED!
One thing. The screen goes black, doesn't go to twrp but Nexus 4 shows up on my PC as MTP. Files are accessible. When I restart the device, TWRP is back to the old version I had.
Not important. Thanks a million buddy. God Speed!

Glad you got it working. Twrp is your old twrp because I just had you boot into it. Not flash it. If you want to flash it, fastboot flash recovery twrp.img

Hi All,
I bought a Nexus 4 on eBay thinking I could fix it but I am really struggling.
The nexus 4 has TWRP 2.8.6.0 but that is all.
I cannot enable USB debugging as I don't have any rom installed.
I have tried a USB OTG cable with power, but have learned that the phone still cannot output the right power? The light on my usb stick comes on but TWRP does not list any USB OTG.
This phone does not have an SD card slot, so I cannot load anthing this way.
Is it impossible to get this phone working?
Kind Regards,

how can i connect a phone with just TWPR to my PC, could this be using MTP?

Have a look at this thread ..
http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312
(Read the thread thoroughly, and take notes, its real easy to get lost in the middle of the procedure and mess it up, and having to start again).
Flashing the stock rom is done entirely via fastboot, so you shouldnt need to worry about adb.
If you can boot into bootloader you should be able to flash stock image, once you get the windows drivers sorted. Luckily I'm on a Mac, so drivers haven't been an issue. I had a similar scenario sometime ago, and after flashing stock, all was good in the world again. I may be wrong, but you'll probably need the latest platform-tools (which contains fastboot) if you're flashing the latest stock images. (Someone correct me if I'm wrong on that one).

This is good information, but I cannot get any further that plugging the phone into the PC, I have tried 4 different usb cables and with them all windows 7 and XP says "unknown device".
I wasn't sent the original cable from the owner which I am asking to do if they have it, but it may be a long shot for them to still have it.
Looks like I need the original usb cable?

I don't think the cable needs to be original, I've used a Motorola cable on my N4 to flash stock, with no problems.
Is the phone in fastboot mode when you connect to pc?
Have you tried these drivers?

For information I am using a cable from a usb cable that came from a Nexus 5.
When the phone is connected to the PC it had an android lying down with an open chest.
When pointing to the android developer sdk drivers as above it does it's usual thing of saying it is already up to date below that still saying unknown device. I'm so frustrated right now.

Can you reboot to the main bootloader screen?
The reason i ask is .. When you see the android lying down is there a list below showing the phone stats? If not, possibly this is why windows is reporting an unknown device.
You should try to get back into fastboot
This has the info to get to bootloader if youre not sure how..

Underneath the android lying down it has:

Above the android lying down I can use the hardware buttons to toggle between "Start | Restart bootloader | Recovery mode | Power off"

Sounds like youre in the right mode. The problem would likely be on the pc/driver side.
P.S. in fastboot mode, you only need to use fastboot on pc .

The driver issue is a massive stumbling block.
I'm still not sure if the cable will work.
I understand I can use fastboot after the PC recognises the nexus 4.
I have a Lubuntu PC this may help me but I have no idea where to start in terms of the drivers.

I use a mac, so im no use when it comes to linux variants etc.
Depending on the power of your pc, you could try using a virtual machine (i.e. virtualbox running windows xp if you have xp disk, or even windows 7). Ive done this before on the mac (xp virtual machine) and it works. This way you can install the correct drivers on a fresh install of windows, without messing with the host OS.
Otherwise, best bet is to uninstall any drivers in your current windows, and install divers from google link i posted earlier.

just outta curiosity, when you plug the phone in (in bootloader mode) change dir to the one with fastboot.exe in and type (in command prompt):
fastboot devices
what output do you get?

Just to check I am doing it correctly, I launch cmd in windows, change the directory to the location where fastboot is and type "fastboot devices". The result of this is it just gives the directory name again waiting for another command.
I hope I'm not coming across as ungrateful, I assure you this is not the case.
