We show that the Weakly Interacting Massive Particle scenario ofproton-philic spin-dependent inelastic Dark Matter (pSIDM) can still provide aviable explanation of the observed DAMA modulation amplitude in compliance withthe constraints from other experiments after the release of theDAMA/LIBRA-phase2 data and including the recent bound from COSINE-100, thatuses the same $NaI$ target of DAMA. The pSIDM scenario provided a viableexplanation of DAMA/LIBRA--phase1 both for a Maxwellian WIMP velocitydistribution and in a halo-independent approach. At variance withDAMA/LIBRA-phase1, for which the modulation amplitudes showed an isolatedmaximum at low energy, the DAMA/LIBRA-phase2 spectrum is compatible to amonotonically decreasing one. Moreover, due to its lower threshold, it issensitive to WIMP-iodine interactions at low WIMP masses. Due to thecombination of these two effects pSIDM can now explain the yearly modulationobserved by DAMA/LIBRA only when the WIMP velocity distribution departs from astandard Maxwellian. In this case the WIMP mass $m_{\chi}$ and mass splitting$\delta$ fall in the approximate ranges 7 GeV $\lesssim m_{\chi}\lesssim$ 17GeV and 18 keV$\lesssim\delta\lesssim$29 keV. The recent COSINE-100 bound isnaturally evaded in the pSDIM scenario due to its large expected modulationfractions.
