 Is there a way how i can check if the sonoff basic has its original firmware after buying from ebay reseller?

I see that sonoff can be easily modified, so i am afraid if the reseller could hack the sonoff to be able to gain access to my network.
Thats why i would like to be sure that there has nothing been modified on the firmware.

Is there a way to check or to reflash the firmware to be sure?

THanks

just buy from Itead or a registered reseller ...

For next time ok, but i already bought from someone in my country to not have to wait 30 days for delivery.
Is there a way how to check if firmware is not modified or reflash it with original to be sure?

 

no

DHL delivers in 4 days worldwide ... if time is an issue ...
