Root [Virgin Mobile/Sprint] LS720ZV7 update killed my root ... Optimus LG F3

You could try this. I've used this method on every phone i rooted even this one at first then i went and did it using saferoot.

Saferoot doesn't work with LS720ZV7. You will need to use towelroot

Check the Psycho Billy rom thread for directions. It's in the second post.

 

Try factory resetting your phone and then re-installing and re-running towelroot.

I was already rooted with saferoot on v6 before running the upgrade. All I needed to do run towelroot as SuperSU was already installed on my phone.

 

I don't know how to help you.

 

Use the unbrick guide to roll back.

 

It does. Just need root...

 

Today while checking my gmail on my phone I seen there what a update. I try to apply the update but it kept failing cause I was running V6 rooted. So I had to do the unbrick on my F3 and then apply the V7 update.

Now my F3 is running the V7 update and is rooted again. I used TowelRoot to root my F3 phone of course.

 

After installing super user, open it and update the binary. Then open busybox and install the recommended option. Then try again...

 

Search for a app name vroot in ur browser and down it and it should root ur lg f3

 

having issues also. I cant even get superSU to work now

"There is no SU binary installed, and SuperSU cannot install it. This is a problem!"

I go to remove and reinstall it, but only get the option to uninstall the update in system/app. Play store only gives option to update or open.

 

Did you run towelroot?

 

I need superSU 1st I thought?

 

You need to root before the superSU app can work. You can install superSU but it won't do any good until you root with towelroot.

 

guess I have no idea what I'm doing on this one. I open the towelroot page on my phone and click on the icon correct? It just opens a new page, the same page, over and over and over until I stop it myself.

 

Use your computer to visit the page. Download the app and then copy it onto your phone

 

clicking on the icon on my computer just opens a page full of code.

 

I don't think you should root your phone. I don't think it's for you.

 

lol, I just copy the code in a text and make an apk with it?

I already had it rooted fine before v7. Now Im having all different issues.
