LG Tool Flash error: upgrade stopped due to an error

Hello I'm having trouble installing the ROM on my LG E467F device, the device is not turning, it hangs on the logo of LG, I first downloaded the LGmobile Support Tool but when I click Recovery Upgrade appears "to upgrade items to fix," then I tried to update the LG Flash Tools 2014 but when arrive in installing the ROM hangs in 4% and sometimes up to 5% with the error: "upgrade stopped due to an error" then click on Retry several times, and the error persists , is there any solution for this? Depending on the phone and I can not afford to buy another :(
