I am in the following situation after an OTA (I was root).
Stuck on the LG Logo, with the LED going from green to BLUE.
No Recovery Mode, No Download Mode, No Fastboot, No ADB shell.
When I plug in Linux I get:
[84488.776042] usb 1-4: new high-speed USB device number 17 using ehci-pci
[84488.908859] usb 1-4: New USB device found, idVendor=1004, idProduct=61f1
