Bootloader CN to US

Hi there, can someone help teach me how to update the bootloader entry from CN to US for GL-SFT1200 and AXT1800? I bought these in Hong Kong (I am Hong Kong based) but the seller probably parallel imported them from mainland so there is no VPN. Thanks!

If you are in Hong Kong, bring the router to our Hong Kong office and we will do it for you.

Sciene Park? Just walk in? Can you pm me the contact person, and I will bring them in this week. Thank you!

Pls contact via email: cs at gl-inet.com

Thank you, alzhao. Just emailed. Many thanks for your guidance.
