Need to Update to 4.2 bootloader

[HellRaiser9101]

Hi guys , I'm currently on Nightlies 4.1.2 JB (unlocked and rooted) and I want to install a 4.3 JB rom onto my tf300t. BUT I need to update my bootloader to 4.2 as stated by the instructions . How do I go about this? I've looked at multiple threads but cant seem to find a SOLID answer/procedure to do so.

Thank you for your time.
