[Q] USB and recovery problems after OTA upgrade to 4.3

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.

Yes.

Try another driver source. Wugfresh's installation is a lot tougher than Skipsoft's, but try the other guy 's system.

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.

I've solved my issue

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.

Nexus doesn`t appears in device manager. At all. It starts to charage, but no reaction in device manager, no any reaction(except charging) at nexus. On computer it looks like i didn`t connect anything. I`ve trying to intall drivers as legasy hardware, but nothing changes. Sorry for my english.

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

Cannot install drivers to make adb work

Hello. I'm trying to make adb work in Windows 7 x64 SP1 (updated) with my Nexus 4.
I enabled USB debugging and it shows up as "Nexus 4" under "Other devices" in Windows' Device Manager. I tried installing Google's drivers from the Android SDK, but it can't find any drivers. Same results with the "Universal Naked Driver".
The device ID it shows is USB\VID_18D1&PID_D002&REV_0228 (see attachment), which I couldn't find anywhere. Is this normal?
Thanks.

You have to right click on the other drivers folder and then update drivers. But you have to have the adb drivers download for it. The only thing is that you need the drivers. Try to search for nexus 4 adb driver download.

What do you mean? I right clicked "Nexus 4" in the Device Manager, selected Update Driver Software, chose the sdk\extras\google\usb_driver folder, but nothing. Please see the attachments. Is that what you meant?
Same thing happens with the "naked" drivers. None of them has the VID_18D1&PID_D002&REV_0228 device ID.

That's right update driver but you need the adb drivers. Go to Google and search for nexus 4 adb drivers download.
Have you tried turning off your phone and then plugging the phone to your computer? That should automatically download the drivers but someone's you get errors. I could not do it done I soft bricked my phone and only the LG logo came on with security error. I flashed the prada adb drivers to get into fastboot.

the easiest way to install the drivers, imo, is reboot to the bootloader, then plug the usb cable in. it should automatically trigger them to be installed.

Thank you, So Much, spent about 30 mins trying to figure this out.

[FIXED] PTP works, MTP doesn't work. Why?

So I got another Nexus 4 for my sister. My computer didn't have a Nexus 4 toolkit, so I thought I didn't install any drivers on my comp, so I downloaded Nexus 4 Toolkit and installed the drivers. I connect her phone to my comp. It installs the adb driver and says device is ready. I go to My Computers and I don't see it there. I uncheck MTP. Computer proceeds to try and install and random driver and said it failed. I check PTP. Computer successfully installed driver and ADB works. ADB doesn't work for MTP.
So I uninstalled all the drivers thru device manager and through Wug's toolkit. I rebooted my computer. I reinstalled all the drivers. I connect my sister's phone. Same issue. I connect my phone. Same issue.
I go install the drivers again on another computer in my house that guarantee has no drivers before. Same problem arises. I tried my phone too, and it doesn't work. I am not running stock. I am running SpeedX ROM.
Help please?
[THE FIX]
1. Download Wug's toolkit
2. Use his Full Driver Installation guide to uninstall all drivers.
3. Install PdaNet Drivers, following the instructions given (Pick LG instead of "others")
4. After installation, turn off usb debugging, and open device managers.
5. Connect phone, making sure it's in MTP mode.
6. Observe in device managers that something popped up (Should be something something subbranch Nexus 4 with a yellow triangle)
7. Right click> Update driver
8. Browse my computer for driver software
9. Let me pick from device on computer
10. Pick the MTP USB Device
11. Let it install.
12 Done!

ADB doesn't work

When I plug in my phone to my PC the only thing that happens is it begins charging. Doesn't show signs of adb working, only thing that happens beside charging is my pc says it's an Unknown Device.
I tried all sorts of things, like USB Debugging on and off, MTP on and off, PTP on and off, I think even fastboot doesn't work. I tried to install all kinds of drivers (official, unofficial, uninstalling them afterwards if they didn't work ofc), I tried Wug's toolkit, nothing. I tried killing adb server then restarting it - nope. I even tried all of my USB ports, both 2.0 and 3.0. Also tried 3 different roms/kernels (L dev preview, Purity and Mahdi), didn't work aswell.
Things seem pretty hopeless at this point :/

Download wugfresh toolkit... look In the section of driver installation... They'll help you out

driver installation...

As I said, I already tried the driver thing in Wug's Toolkit. Also my Windows allows unsigned drivers.

Bump :/

If it still says Unknown Device on your PC, its a driver issue. Personally I use the Google usb driver, that page also has instructions on how to install the driver. Try uninstalling whatever drivers you have installed right now, then install Google usb driver carefully following instructions. Fastboot needs bootloader mode, so make sure your phone is in that mode before trying a fastboot command. I use the Minimal adb installer to install adb/ fastboot tools.

Fastboot actually works, only ADB doesn't. I use the Android SDK to install adb/fastboot and I tried Google USB drivers and also Universal ADB. I tried the drivers from Wug's Nexus Toolkit and then LG drivers, same old story :/
Edit: I upgraded from Windows 8 to Windows 8.1 using clean install, still same problem.

Might be windows 8/8.1 giving you driver signature grief. Try the Universal adb drivers:

Nexus 4 will not show up on Computer

Nexus 4 when plugged in with 2 different cables (both capable of transferring MTP as tablet transfers files and connects as MTP just fine) don't do anything and just charge the phone . No "connected as a media device" notification. Checked settings and it's on debugging mode as well as MTP mode but still not being recognised and the same applies for PTP. Phone has been factory reset and still does not get recognised by computer. Device Manager doesn't pick up anything either. No ADB, Nexus 4 name in Device Manager. What's the problem and how can i get it to show up on computer as an MTP device? The phone's not rooted and is Android Version 5.0.1 Lollipop.

Good luck

Had the same issue my USB port on my Nexus 4 was going bad, but it was still charging the phone. I replaced the port and was back in business.

You could try and install ADB drivers . It might help the pc detect.

N4 will not show up as MTP in android
If you want to use MTP, it is supported in TWRP recovery.
Boot into TWRP recovery and you can view and transfer everything in N4 /root via windows explorer on PC.

mine once had MTP work flawlessly until i start to done this and that, now whatever i did only PTP works
boot to TWRP? sadly nothing work ?

If your bootloader is unlocked, you can flash or boot into TWRP recovery, it supports MTP.
If you have any connection problems between PC and TWRP MTP, it is likely driver related.
You will need to look in Device manager on PC while phone is connected.
Download the howto_driver.zip from the "15 seconds ADB Installer thread" and follow the picture tutorial contained in the zip file. This should fix your connectivity issues.
If you are sill having connection issues, You could try and install ADB drivers . It might help the pc detect.

32bit
Then go back through the picture tutorial in the howto_driver.zip
Best of luck

Nexus 4 Update
Took it to phone technician who replaced battery port on phone. He didn't do a good job on the reassembly of the Nexus 4 when replacing phone battery port and fixed it. Drivers install now.
