It can be re-flashed. Might have the "Programmable code protection" on it. If is brand new, it's normal to show that 3FFFs.

knwn good r-tuned pic is full of zeros. so maybe encrypted shows as zeros?

Better wait for an more experienced user. My knowledge on PICs is quite limited.

either empty or protected, anyway. It could be erased and re programmed if there are known good dumps.

The following programmer settings should be used.

Oscillator: HS
WDTE (watchdog) disabled.
PWRTE (power up timer) enabled.
Code Protect: All protected
MCLRE should be set to internal also called "disabled"
BOREN/BODEN (brown-out reset) disabled.
LVP (low-voltage programming) enabled.
CPD should be 0, meaning that data code protection is on
This should give a config word of: 0x1e82
