Not trying to be mean but some people aren't as nice as me. So I'm only going to say this once search the thread. Better yet look at the stickied posts and go through them with your peepers and omg I think there is a thread about a brick recovery. It's kind of a pain in the ass but once you have all the nessasry tools and files create a folder where you keep all of your phone stuff on your desktop. Then create a folder called Lg Optimus f7 full flash recovery. Save the tools and the original firmware zv4 file in that folder. And read the folllowing tut from one of our other lovely members who beat me to the punch on writing a hard brick recovery guide. About a year ago... Lol. Here it is:

This guide is intended for windows users. There is no way to unbrick this phone unless you are on windows due to the software being used for flashing only made for windows.
Put your LG in download mode:
While powered off, volume up + plug in USB (thanks sortoh85). Connect a trustworthy USB cable
Open up LG Flash Tool
Tick "Select Manual Mode"
The DLL selected is called "LG870_20130528_LGFLASHv151.dll", find where you extracted that to
Select Add, choose the tot file you downloaded.
Press ok.
Let me know if I can assist you any further.
