I experienced this issue on 2 of my Android phones, namely Nexus 5 and Galaxy S9 Plus. That’s to say, if your Galaxy device has 512GB of internal storage, you may only be able to see and use only 256 or 128 GB of storage space. A wrong PIT file might configure your device’s internal storage improperly.If your Samsung Galaxy device is stuck in a boot loop or it is not getting past the Samsung logo, you’ll need a PIT file.
You are supposed to flash a PIT to fix things. The partitions on your device may get messed up while installing the stock ROM.
Odin requires Partition Information Table to map and allocate different partitions on your device.‘ Hidden.img‘ error while flashing firmware in Odin.
