Having read this thread and trying everything here plus other things, I still have a bricked LG V410.
I'm using Linux. Doing lsusb shows the device, but thats about as far as it goes.
from lsusb: Bus 001 Device 012: ID 1004:61f1 LG Electronics, Inc.
from adb devices: List of devices attached
from mtp-detect: libmtp version: 1.1.8
Listing raw device(s)
Device 0 (VID=1004 and PID=61f1) is a LG Electronics Inc. Android phone (ID1).
Found 1 device(s):
LG Electronics Inc.: Android phone (ID1) (1004:61f1) @ bus 1, dev 12
Attempting to connect device(s)
PTP_ERROR_IO: failed to open session, trying again after resetting USB interface
LIBMTP libusb: Attempt to reset device
LIBMTP PANIC: failed to open session on second attempt
Unable to open raw device 0
OK.
So, it appears as though Linux can see the device, but that's about it. Interestingly, if I put the device into Download mode (holding down the Up Vol while plugging in the USB cable), Linux will not see the device.
I can also put it into Factory Reset mode using the combination of keys, but that just get it stuck at Factory Resetting on the screen. I've even left it like that overnight and it's still sitting like that the next day.
I'm open to any ideas you folks may have.
