Every soul is already omniscient.
Not potentially — actually, and buried. The soul in its own nature has infinite knowledge, infinite perception, infinite bliss and infinite energy, and karma is the dirt on the lamp. Nothing is added by the path; something is removed.
The Jain account of the soul is unusual in being entirely positive about what is already there. Every jiva possesses ananta jnana, ananta darshana, ananta sukha and ananta virya — infinite knowledge, perception, bliss and energy — as its intrinsic nature, not as a potential to be developed. What obscures them is karmic matter, and the four ghatiya or destructive karmas specifically block those four attributes. The standard image is a lamp inside a pot, or a mirror under dirt: nothing is added by the spiritual path, something is subtracted. This has two consequences worth noticing. It makes the tradition radically egalitarian at the level of metaphysics — the soul of an insect and the soul of a Tirthankara are identical in nature and differ only in what is stuck to them — and it makes grace structurally impossible, because there is nothing anyone could give you that you do not already have.
