Hi everybody, 2 months ago I tried to encrypt my nexus using the security settings. When my n4 rebooted the touch stopped working. I couldn't use the recovery becouse the data partition was encrypted, so I used this tutorial (http://forum.xda-developers.com/nexu...ck-n4-t2347060) to reset my phone. Now windows (neither ubuntu) do not recognize the n4. I tried to follow any kind of guide or tutorial i found but uselessly. I'm desperate, the recovery doesn't work, if i try ,it stop on android logo saying "no command". Entering in windows device manager (after i formatted my pc) the nexus is seen as "full jellybean on mako", i tested this driver (http://forum.xda-developers.com/nexu...stall-t2411201) but the situation has not changed. I hope someone can help me.

Does your phone boot?


BTW, if you need only driver download from this thread: http://forum.xda-developers.com/nexu...ndows-t1992345

Boot into bootloader and flash stock rom from here :https://developers.google.com/android/nexus/images

BTW, did you enable developer options?

Sorry, I misread your answer. "It works perfectly" means that i can use it to call or whatever. Using the key combo (vol up+vol dw+power) it doesn't boot in download mode. I think it isn't a driver problem, something in my n4 went wrong. It boot only in fastboot mode and the recovery doesn't work.

If it boots into Fast-boot/boot-loader then problem is solved right. Does your PC recognise your phone when it boots into fastboot mode? If yes then open up terminal and type:
Code:
fastboot oem unlock
Then open the downloaded image from here https://developers.google.com/android/nexus/images and Execute the flash-all script. This script installs the necessary bootloader, firmware,and system. Wait for a couple of minutes and then phone will reboot itself. After phone boots enable developer options in the phone and enable USB debugging.

If you are still not able to mount the storage in Ubuntu, you can install the mtpfs tool for Ubuntu.
Code:
sudo apt-get install mtp-tools mtpfs
sudo gedit /etc/udev/rules.d/51-android.rules
and in the 51-android.rules write the following:
Code:
#LG – Nexus 4
SUBSYSTEM==”usb”, ATTR{idVendor}==”1004?, MODE=”0666?
Then do:
Code:
sudo chmod +x /etc/udev/rules.d/51-android.rules
sudo service udev restart
sudo mkdir /media/nexus4
chmod 755 /media/nexus4
sudo mtpfs -o allow_other /media/nexus4
This should get it working. This thread tells everything in much more detail if you still didn't get it to work.

If no pc will recognize it it's probably your pc port on the device. Have you tried different cables too? It's pretty easy to replace or have replaced.

Seems like something going wrong with drivers, open the device manager on windows, plug in your phone (in fastboot) and uninstall the driver. Then use this http://www.koushikdutta.com/post/universal-adb-driver

Dunno what that full JB driver is about but it doesn't seem right.

You might have to repeat this process when phone is booted normally too if it won't connect via MTP
