I fear that if all the leaves are squishy and clear then the plant is done for. The fact that you said it had barely any roots means that any water would probably only have made it worse and it sounds like you watered it. If the plant has little or not roots, it is has hard time taking up the water, so it is better to leave those pretty much dry. Wetness around these kind of plants that are in distress usually gets them - as I can attest from my own many Aloe failures. In my case it is usually late night summer heat (90F plus) and too much water, but it kills them nonetheless.
My advice would be to get a new one rather than keep messing with this one, which is done for.
