We study the information paradox of four-dimensional covariant black holes inspired by loop quantum gravity (LQG) with two well motivated solutions. We first prepare the spacetime in the Hartle-Hawking state, compute the radiation entropy, and recover a linear growth at late time. When considering the mass loss and incorporating graybody factors, we show that for Metric 1 the LQG parameter $\zeta$ leaves temperature and Planckian factor of the spectrum unchanged but enhances the near-horizon barrier, leading to a faster evaporation rate as $M$ decreases. This behavior contrasts sharply with Metric 2, which has slow evaporation rate at small $M$ and admits a nonsingular continuation suggestive of a remnant or a black-to-white-hole transition. We then apply the island prescription on the eternal background and find that quantum extremal surfaces exist in Metric 1 geometries; $\zeta$ gives a larger island and the island suppresses the late-time entropy growth, preserving unitarity. Our results highlight that covariance-respecting LQG black hole do not exhibit a universal late-time behavior.
