Hi there !
You do not need usb debugging for adb sideload for LG G Flex. If your ROM was fully installed before the kitkat update,
1. Send the update.zip file via adb sideload.
2. In recovery menu "Apply update from ADB" the update.zip file is sent to your usb-connected phone.
For the installation of LG Kikat update you must send the update file three times via adb sideload. Don't reboot system before you have sent it three times. Unzipping and installation take place in well ordered ranges and will complete after you have sent the file three times 100%.
