LG G Stylo authentication fail #9 - Android Q&A, Help & Troubleshooting

I recently just bought a new LG G Stylo with MetroPCS. this is my first time being with android so i took it upon my self to root the phone and see what all i could do with it. Everything worked fine for a couple of days then i tried to reset my phone and when it tried to come back on the lg logo cane up and it said Authentication fail #9. I try to factory reset the phone but it goes back to the same screen. I can not put the phone in download mode and my computer does not detect that there is a phone there. If there is anyone who can help me please it will be greatly appreciated.

I bricked my rooted Lg optimus F6 please help!!!

Ok so I rooted my LG Optimus F6 yesterday, I used root uninstaller to get rid of stock apps but by accident or careless I must have deleted LG setup wizard.. I later on that day Master Reset the phone and Now I can't get my phone to load up.. It turns on and brings me to LG setup wizard but says it unexpectedly stopped, I've tried hard resetting and I've went into safe mode and it brings up the message at the home screen, Home screen has unexpectedly stopped. Is there anything I can do to restore my phone back or somehow download setup wizard and install on to my phone from the PC. Also my PC isn't recognizing my phone so I can't even get into the files from the PC.. PLz help me out with this and let me know if theres anythin I can do.

If you have a custom recovery installed than you can just flash the stock rom LG has provided for the public.
This happened to me not to long ago. The LG support tool is the software you'll be looking for. Download, install, connect device while holding up and use the tool to do the rest.

Need Help with mostly dead LG Volt

My LG Volt had been freezing frequently and I would have to restart the phone .The last time it froze it would only turn on to the LG logo. I can get in to recovery and did a factory reset , a couple of times, but that did not help. I have looked at a number of forums at various sites trying to find a way to root this and hopefully restore the phone. One problem is that the computer does not recognize it. Any help would be greatly appreciated ! This LG Volt is running android 4.2 . It came with it . I was sent a replacement phone last Feb. but I know it was still android 4. . :crying:
