BEFORE beginning the Unlock Bootloader process your product requires that you update the ROM to the version listed in the table below first, then download the RUU next to it to enable the unlocking capability.

NOTE: If you do not find your ROM version in the table below, and your ROM version is newer, then your device does not require the RUU. Please bypass these steps and continue to the next page.
