solution
The way in which I solve it:
Get off the "LGMobile Support Tool"
-start The program
'I take out the battery to cel and after about 5 seconds to put the volves
- Mantenes tight volume + and connect to PC via USB (if you do not recognize the cel instead of volume + got to hold down volume + and volume - the idea is you enter the download because otherwise the program will not recognize the cel mode)
-A See that you recognized in the program you additional> Error Recovery Features actualisacion
- Seguis the step that gives the cel and ready restarts (the only thing is I lost the root to do this, but other cell was the same as before)
I hope it helps someone, Greetings
