Late but not least
I've been searching the web for how to root LG Optimus F3 for VM, I found nothing. I tried looking on how to root any Jellybean device all I got was a reboot and nothing. After upgrading from a Kyocera Event and having it root, I've missed all the features and it has just been one day. Can someone please share any information they have, on how possibly I can root my device.
Thanks!
Ok so i am now rooted thanks to myself only got out dated answers this worked for me with my LG ls-720v7 (4.1.2 - jb)
First step download. SManager from market
Then get towleroot.apk link below
towelroot com/tr.apk
Then install the apk find it in your download directory but first make sure you allow unknown sources in settings_security after thats installed run it download su and busybox from market and then use root checker to see if you are now rooted.
O cant figure out how to swap internal with ext. Try this it also worked for me. Download Uni-init v1.0.apk from the market install it run it Click on Activate and allow with super user Click on Verify to make sure init.d is enabled Reboot your device Download any Root Browser you like from the play store or use smanager if you still have it Download 11extsd2internalsd from below
www mediafire com/view/8pwu65zzd10ow5z/11extsd2internalsd
copy it to your sd card Open Root Browser and copy 11extsd2internalsd and paste it /system/etc/init.d folder Hold click 11extsd2internalsd and set permissions and make sure everything is checked as far as Read, Write, and Execute. Open smanager and allow with root access Go to /system/etc/init.d and click on 11extsd2internalsd Click at the top where it has Su (lil android head) and Boot icons and hit save and then exit Reboot your device and your all done!
