SOLUTION:

Rearrangement of the primary to secondary carbocation.
The carbocation moves to a tertiary position by methyl rearrangement.
Carbocation rearrangement from secondary to tertiary position.
Carbocation rearrangement from secondary to tertiary position.
Ethyl rearrangement that manages to stabilize the carbocation, taking it to a tertiary position.
