The major product in the given reaction is

In first step of the reaction ${\mathrm{H}}^{+}$ will attack on the lone pairs of electrons of the oxygen atom. Which will get dehydrated forming carbocation intermediate. On this carbocation pi bond will attack forming a five membered cyclic ring. In last step ${\mathrm{Br}}^{-}$ will combine with carbocation forming final product according to the following reactions.
