I have an LG Optimus Fuel (LG L34C) from Straightalk running Android 4.4. This phone is (as far as I know) the same as the LG Optimus Zone 2 from Verizon Prepaid.
I couldn't find a halfway decent manual for the LG L34C so I followed the LG Optimus Zone 2 Manual to enter Recovery mode. When I held the buttons on the L34C, it would boot, show the LG logo, then shut off, show the LG logo, and do it again. As long as the buttons were held in would loop.
So I downloaded the ADB and tried to do it from there.
"adb reboot recovery" brings up the classic "No Command".
"adb reboot bootloader" just reboots it.
"adb reboot download" just reboots it.
"adb reboot fastboot" just reboots it.
What the heck is going on! I'm going crazy trying to figure this out. Why can't I access any of the special menus?
Oh, and TowelRoot didn't work to root the phone either.
