Mechanism for reaction of enol ether with HBr

[![the question with my mechanism](https://i.stack.imgur.com/XkPYX.jpg)](https://i.stack.imgur.com/XkPYX.jpg)


Please refer to the image for the question. I tried two different mechanisms for the reaction (1 and 2) and ended up with two different products. Now I can't decide which of the two mechanisms would give the major product. 


I think that mechanism 1 should give the major product as it involves the formation of a double bond between $\ce{C}$ and $\ce{O}$ atom which is thermodynamically favorable. Is this reasoning correct? 


The answer to the question had given product of mechanism 2 as major product. But I don't know if it is really correct or not.
