Internal Storage issue topic

Hello all, is there a trick to accessing the full amount of storage after several ROM flashes? My p3113 is low on storage, but the numbers just don't add up. The total space says 4.59GB (assuming system eats up the rest of the 8GB) but when I add up the usage stats its only roughly 2.8GB. And it is telling me only 516MB available? Any help would be much appreciated.Attachment 2589937
