After Michael's death, Synadenos became one of the earliest and most important adherents of Michael IX's son, the young
Andronikos III (r. 1328–1341). Andronikos had been disinherited by the old emperor,
Andronikos II (r. 1282–1328), after Michael's death. Along with the fellow aristocrats
John Kantakouzenos and
Syrgiannes Palaiologos, Theodore formed the leading "triumvirate" of the younger Andronikos's supporters, to which the "

. Throughout the conflict, Synadenos was among the most radical and uncompromising supporters of the younger Andronikos, favouring the eventual deposition of Andronikos II.
During the course of the war, Synadenos defeated loyalist forces under
Constantine Asen,
and in the final round of the civil war, in 1327–28, he served as governor in Thrace.

, switched over to Andronikos III's camp, Synadenos along with Kantakouzenos urged Andronikos III to march on Constantinople and depose his grandfather outright. On the night of 13 May 1328, the three men led their army through a gate after bribing its guard, taking possession of the imperial capital without resistance. Andronikos II was forced to resign the throne and retire to a monastery, with his grandson succeeding him as sole emperor.
For his services, Synadenos was promoted to ''
protostrator'' sometime during the civil war, perhaps as early as 1321.
After the war, Theodore Synadenos was rewarded by being made
governor of Constantinople, Apokaukos became head of the imperial secretariat, Kantakouzenos remained Andronikos III's principal advisor as ''

In late 1338, however, a revolt broke out in Epirus in favour of
Nikephoros II Orsini, the last descendant of the Epirote ruling dynasty. Synadenos was taken captive in the capital,
Arta by the rebels, and remained a prisoner until 1340, when Andronikos III and Kantakouzenos campaigned against the rebels and recovered the region.
John Angelos, a relative of Kantakouzenos, was installed as the new governor, while Synadenos was moved to the governorship of Thessalonica.
Renewed civil war and death

In June 1341, Andronikos III died suddenly, and a power struggle developed between Kantakouzenos, who initially assumed the powers of regency over Andronikos's underage son

John V Palaiologos or Palaeologus (; 18 June 1332 – 16 February 1391) was Byzantine emperor from 1341 to 1391, with interruptions. His long reign was marked by constant civil war, the spread of the Black Death and several military defea ...

and Thrace. The common people, impoverished by an exploitative and over-powerful aristocracy, viewed Kantakouzenos as a representative of the hated aristocrats and rallied behind the legitimate Palaiologos line and one by one, the cities were seized in the name of the Constantinopolitan regency.
[Bartusis (1997), p. 95] Thessalonica at first remained tranquil, and Synadenos contacted his old friend Kantakouzenos with the intention of surrendering the city to him. Such a move might well prove decisive, as possession of Thessalonica would enable Kantakouzenos to control Macedonia,

Apokaukos with a fleet came to reinforce the new regime, and one of his sons was installed as its new governor.
Driven from Thessalonica, with Kantakouzenos's cause seemingly in ruins—he was soon forced to seek refuge in the court of the Serbian king,
Stefan Dushan—and with his family back in Constantinople in the regency's hands, Synadenos made terms with Apokaukos.
He was rewarded with the high rank of ''

[Guilland (1967), p. 486] A year later, in February 1347, Kantakouzenos entered Constantinople as the victor of the civil war, which had left the Byzantine state in ruins: its human and military resources exhausted, over half of its territory lost, bankrupt and indebted to foreigners, with a war-weary and unenthusiastic populace.

Some time before 1320, Theodore married Eudokia Doukaina Komnene Palaiologina Synadene, daughter of the ''
