Nexus 4 not detected on PC - Need to lock bootloader - Nexus 4 Q&A, Help & Troubleshooting

So I've been having some SERIOUS issues with my battery and have requested an RMA. Last night after a ton of issues (and at one where I soft-bricked pretty badly) I managed to unroot + load stock 4.2.2. It was late at night, so I decided I would re-lock the bootloader later.
Fastforward to today, I enable usb-debugging mode, plug in the phone and Windows 7 gives me an error. It says there's an issue. I go to device manager and it shows up with the yellow logo. I figure it's a driver issue so I uninstall drivers, and re-install naked drivers .72. Restart, plug it in and the same issue.
I go to a different computer and try it, same pop (this is Windows XP) saying device not recognized.
I also noticed my device no longer charges from the computer, when I plug it in it charges for a second, then stops.
How do I lock the bootloader if I cannot connect my Nexus 4 to the computer?? I tried going to bootloader and connecting the device, but nothing happens at all there. SOMEONE HELP!
EDIT: Here's the error message in Windows under the device manager: "windows has stopped this device because it has reported problems. (code 43)". Getting panicked now.

Search for BootUnlocker in the play store. Never tried it myself but by the reviews it seems to work. Good luck.
Edit: just saw that you have to be rooted. Sorry.

Yep saw that one too.
I'm pretty much stuck. There's literally nothing I can do except hope it somehow magically works later on...
Would Google accept the phone as under warranty if the bootloader is unlocked? The battery is SHOT, like it drains 1% every min while under use + like forever to charge. My hope is that the thing never boots when they get it so they can't actually see that it's unlocked.

Try using a different usb cord and I'm not sure if Google will accept it.

Have already tried using 2 different cords. I'm going to try out another computer tomorrow that's brand new and see if it works there. Will also try charging fully but I don't see how that would affect it.
Still leaning towards them not being able to turn it on as a pass. That's the best possible case scenario for me.

I had same issue but try to update drivers of or PC
And install an app on or n4 called sdscan it will fix this issue

Tried it, doesn't work. Also, the issue isn't with the SD card since it mounts just fine on the phone itself. Issue comes up only when connected to a PC.
It doesn't even charge from the PC USB port.

I had this problem. Here is how I fixed it. I deleted all Android phone and USB storage drivers from my computer. Then I plugged in the phone to USB. Then I quickly removed the USB from the phone while the computer was looking for drivers. Then everything worked fine again.

If it's just for wiping why don't u do a format USB?
Oh I guess u wanna backup too... if u have wifi just connect via wifi and copy files... u can access ur comp from es file explorer on wifi
Wow I had this same problem about a week and a half ago. I never did find a solution. I tried multiple computers. I couldnt even unroot it because the computer did not detect it even in fastboot mode. I ended up sending it back to samsung to be repaired.

What data are you trying to backup? I would go into recovery, wipe data/cache, reflash the ROM, then test it.
You can backup apps/settings with titanium backup before you wipe.

Fixed mine with some serious cleaning of the USB port. I also tried buying a new cable, downloading drivers, etc. in the end, it was just a bad connection.

I've tried many cables, almost positive mine is a pure driver issue.

I've tried absolutely everything in this thread. Lost USB connectivity completely on my phone. Doesn't matter what machine, what OS, or what cable, or what drivers are installed. I'm assuming it must be a hardware issue at this point. Doesn't even work in bootloader.
For those updating OTA to 2.3.6 via OTA and needing to re-root their phones, make sure you're not having this issue. Being stuck without root is a pain in the ass!
Clean your USB port on your nexus! Clean it well.

Good advice actually. Scrubbing it with a dry toothbrush + using a a brand new 3 inch USB cable made the sucker finally connect.
Must have been a combination of bad cables and poor USB port hygiene
Yep, had to take a knife, brush, and alcohol swabby to mine.

Curious... Did Odin work for you with the old cord? Or transferring files to the sd card? I ask because ADB doesn't work for me since upgrading from Win 7 32 to 64. I can get a little bit of logcat to run sometimes and it hangs but Odin works flawlessly. Have tried several cords (that also work on an old Windows XP machine I have) with no luck. I guess I could try a new cord but that doesn't make sense to me

That's one way of fixing it. I also had the same issue, resolved first removing all the drivers for the phone, updated chipset drivers, reboot, re-installed the phone drivers, reboot then plugging in the phone.
Just in case someone else has the same issue and doesn't want to re-install windows

[Q] nexus died while data transfer

Hey, so my nexus died while it was connected to a PC. I was sending a movie to nexus but the transfer was frozen so I decided to pull out the cable/don't judge me/. After that I realised that its off and doesn't react at all.
If I connect it to PC it tries to install apx driver without success.
It doesn't boot/adb won't find device.
Any chance to wake it up? Guess I should use warranty.

Have you tried holding the power button for 20-30 seconds?

Of course that was first thing I did also with hard reset.

Hi, margaretiak...
Some questions....
What do you see when you plug the Nexus 7 into the charger?
Do you see the WHITE-ON-BLACK battery charging animation?
Do you see anything on the screen at all? Any hint of illumination?
Sorry for all the the questions.... just trying to better understand your situation.
Have you tried these various button combinations?

If you're PC is trying to install APX drivers, that, unfortunately, is not a good sign, as it's suggestive of a dead bootloader. APX drivers are typically used for nvFlashing, amongst other things, bootloaders. Unfortunately, nvFlash in APX mode, for the Nexus 7, is a mystery that thus far, nobody yet has been able to crack.
If you do have a dead bootloader, there's really not much that can be done, other than an RMA under warranty.
Very unusual, though, for a file transfer to cause this kind of problem...
Rgrds,
Ged.
Yep,it's totally dead. Display is off. Well I havnt lost anything important guess/got tib in PC/ so I'll get new one nexus. Hope they can't find out that it's rooted/modified.
And few days ago I had also problem with nexus. Guess also while I was transfering files..but via USB otg. I lost connection to HDD and then nexus has turned off. When I tried to turn it on, nexus was blinking/flashing. After some time I managed to boot into recovery so I deleted caches and it worked.
Sent from my Galaxy Nexus using XDA Premium 4 mobile app
The HDD removal crash is a bug in the kernel. But it shouldn't kill your device completely like that.
Shouldn't but it did. Running slim ROM 4.2 without any kernel based modification.
Well I'm not desperate since it has the screen lifting from the begin. I just hope I'll get new one or repaired..at least I can add screen lifting to issues.
Sent from my Galaxy Nexus using XDA Premium 4 mobile app
Just to know..they replaced motherboard but in service they made few scratches on my n7 so I returned it with this and also screen lifting (that i forgot to add before)

My phone its not pushing drivers to computer.

Does any body knows why my phone wont push drivers to my computer? It just does it ones in a blue moon. Im on Icerom deodex, i think, because it was unlock which broke the usb drivers command.. i try different roms, port, and usb cable i event reset my computer and install lg divers but it will still not work. The computer doesn't even make a connection sound, and my phone say its charging.

I've been using Airdroid to transfer ROMS to my phone. https://play.google.com/store/apps/details?id=com.sand.airdroid
I have several different drivers, on my Win 7 laptop and Win 8 desktop and nothing has worked. I've tried different cables too. it's also not recognized in ADB at all ever.
I would LOOVE an answer to this. I have no idea what is happening. It's baffling.
OK so I think not sure(something got burn cause I left my phone charging in recovery mode and I felt to sleep and when I woke up in was burning hot?) So I'm wondering if that was the problem ? I'm freaking out cause I'm paying for insurance and I don't wanna brick my phone and not fix it. At least lg tool was able to reset the root counter so I can return it for a new one but now I can't! Now what ?

When you connect the phone to your computer, do you get an RSA security message on your phone allowing the computer to access your phone? I'm asking because I didn't notice the message on mine at first. Once I clicked yes, it was fine from that point forward.
no,nothing...i can just make it charge thats it....even with different leads
Wow, that's a mystery to me. Maybe the usb port is defective?
