Model :

Hardware Version : V1 US?? I'm not so sure

Firmware Version : 1.2.9 Build 151026 Rel. 75883n

ISP :

I bought the device in the Philippines but my Hardware v1 is US. Back of device says (US)/1.1 so I figured this is US. See screenshot https://www.evernote.com/l/AAmSdbOVr6hCApoyOZfwhF7lWlkLqoMizVQ


However, the firmware upgrade versions seems to be all EU. Tp-link website says I have to make sure because firmwares for US and EU versions are different. (See below firmware available to me in the Philippines)


Questions:
1. Is my first interpretation correct that I indeed have the US version?
2. If so, why am I getting EU versions in the Philippine website where I bought the device?
3. Is there a sequence to installing version upgrades or can I just install the latest one?
