Something went wrong when I updated my Nexus 4 (Mako) with Paranoid Android 6 via TWRP 2.8.

I formated the phone in Recovery Mode but now I unable to connect to adb to transfer new OS image in the internal memory. So, I'm stuck with a phone without operating system.

The battery loads well when connected to my debian but I can't see anything related to the phone with lsusb.

I'm definetly not an expert with TWRP, but I noticed an error when I try to start adb sideload : E:Unable to mount /usb-otg.

I'm also considering to open the device but from informations I found there is no way to extract the internal memory to flash it from my debian.

How can I debug that ? Alternatively, what are my options to send a new image to my phone ?

UPDATE 1: When I enter in fastboot mode (the screen with the android picture) I see:

FASTBOOT MODE
VARIANT - mako 8GB
HW VERSION - rev 11
BOOTLOADER VERSION - MAKOZ10o
BASEBAND VERSION - M9615A-CEFWMAZM-2.0.1700.48
CARRIER INFO - None
SIGNING - production
SECURE BOOT - enabled
LOCK STATE - unlocked

In this mode I still have nothing on lsusb or fastboot devices -l.

UPDATE 2: Here is what I see in dmesg -w | grep usb when I connect the phone :

  • Are you in fastboot mode? Don't restrict yourself inside TWRP.

  • I updated my comment with information relative to fastboot mode. I'm definetly new with android, but don't you think I should see something in lsusb whatever mode I use ?

Reset to default

It turned out that the communication problem on the USB bus came from a "loose" connection of in the micro USB. I succeeded to reset a factory image just leaving the phone and the connector in a particular position to keep the contact.
