Help application installation error

[Alexiousnign]

I have been having some trouble with installing applications onto my device for a few weeks now.
I have 1.2 gb free space on my device/ internal sd
(not sure wich because this ****** phone is confusing)
anyway, I was trying to create a second partition for app2sd; I believe that is when I made a mistake.
I don't want to factory reset my device.
My device is rooted with basic superuser permission.
Any assistance would be greatly appreciated.

If you changed partitions in internal storage, you're probably going to have to flash a PT file. But go to a Best Buy store, ask where the Samsung desk is and see if the Samsung people can help you - even if all they can do is tell you what to do.
