Fire up your device in Fastboot mode (Volume Up + Power).
Download this file (I'm assuming you have the I9020T or I9023. This file will NOT work for the I9020A): https://dl.google.com/dl/android/aosp/soju-imm76d-factory-ca4ae9ee.tgz
Extract the .img (there are 6 total) files to an easy location (preferably your Fastboot folder).
Fire up a command prompt and cd your way to your Fastboot folder then do this:
fastboot flash bootloader bootloader.img
fastboot flash radio radio.img
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot erase cache
This will bring you back to stock everything with an unlocked bootloader. If your bootloader isn't already unlocked, you'll have to do a "fastboot oem unlock" before it'll let you flash anything.
If you want to lock the bootloader back up and go back to a 100% fresh out of the box config, do "fastboot oem lock" at the end.
