Not able to update firmware

I am unable to update the firmware on my strip, it is stuck on version 1.4.1_34 and i think newer version is _51.

Also the led strip does not turn on, only the controller does after the update already mentioned

Can i get any help?

Hi, the latest firmware version we has released is 1.4.1_34, where have you got the update info, could you post a screenshot here?

Can not control the light with app, right? could you double check your network of the strip ?
