Concerned for her son Venkata, Queen Mother Varadamba sought the help of Ibrahim Adil Shah I of Bijapur promising great wealth in return.

Rama Raya and his lieutenant, Hande Hanumappa Nayaka, successful in repelling Ibrahim's forces, with a substantial bribe from Achyuta's brother also contributing to Bijapur's retreat.

Horrified by his tyranny, the remaining nobles fled to their provinces and sought the aid of Rama Raya and Ibrahim Adil Shah Ito overthrow Tirumala and end his oppressive rule.

[7] Rama Raya recounted Salaka Tirumala's misdeeds and urged their cooperation, promising substantial rewards and titles for their success in defeating the enemy.

Honoring his pledge of loyalty, Timma Nayudu sheltered Rama Raya despite pressure from Vijayanagar nobles, who arrived with large army demanding his surrender.

[7][8] Rama Raya's victorious army advanced northward into the Kandanavōlu (Kurnool) province, likely to confront enemy forces stationed in the strategic strongholds of Betamcharla and Juturu.

Akkaya Cina Timma Nayaka, a cousin of the Gandikota captain, played a prominent role in the campaign, distinguishing himself in several engagements and contributing to the army's successes.

[8][7][6][3] Adavani, the last significant stronghold in the region still under Salakarāju Tirumala Raya's control, was entrusted to a skilled Muhammadan officer, Sanjar Khan, for its defense.

[8][1] Rama Raya avoided open conflict with combined army of Ibrahim Adil Shah I and Salakamraju Tirumala and resorted to diplomacy.

Through persuasive letters, he expressed repentance and highlighted the dangers of inviting Muslim forces into their Empire including the defilement of temples and loss of sovereignty.

Convinced by these arguments and Rama's pledge of loyalty, Tirumala dismissed the Bijapur forces after paying the promised subsidy of 50 lakhs of hoons and lavish gifts.

The remaining Pedda Tirumala, consumed by despair,[5][6][11] inflicted havoc in his final moments blinding the royal elephants, mutilating the horses, and destroying the kingdom's priceless treasures.

With the unanimous support of all factions,[1][12][2] Sadasiva Raya the son of Achyuta's brother Ranga, was recognized as the rightful heir and ascended the throne of Vijayanagar Empire.
