Because Chernomorets Pomorie did not receive a licence to play in the A PFG, Etar competed in the promotion playoff, but lost 3–1 to Svetkavitsa Targovishte.

А streak of good form in the second half of the season ensured promotion to the A PFG on 23 May 2012 with 1–0 home win against Nesebar.

As a result, the second half of the 2012-13 A PFG season saw a huge turnover in player and managerial personnel[2] (Tsvetanov had already been replaced by Serdar Dayat).

Despite a bright start to the spring season, the increasing financial uncertainty continued to plague the team and Etar relocated to Sliven, in part due to a conflict of interest with the Veliko Tarnovo supporter groups and the municipality, which contributed to the club remaining in the relegation zone.

In May 2013, the team was practically dissolved and Etar's remaining A PFG opponents were awarded 3:0 wins by default until the end of the season.
