I am also very confused, why they are not even replying anymore. Today I tried calling directly to Smartron customer care but they repeatedly cut my call without speaking to me ones. This is making me nervous regarding the fate of users. Since this is a startup, I don't blame them if they are not able to get funding. It's really hard to be a hardware startup in India. But I really hope they survive.
My guess is that the brand and company is alive and well, maybe the forum is not on the priority list anymore.
