Given above is a picture of the back of my Deco M4 (Hardware V2.0). I am on Firmware Version 1.4.3 (as mentioned above). I am from India and the latest firmware version has not been released on the TP-Link India website. I would like to know whether it is safe to upgrade the firmware from:

the TP-Link UK Site: Deco M4(EU)_V2_1.5.0_20210511 (Multi-language)

or

the TP-Link US Site: Deco M4(US)_V2_1.5.0_20210511 (English).

If it is safe to upgrade, kindly advise which firmware I should use.

Thanks and regards
