Data recovery from bricked and encrypted device after factory reset possible?

[swfjvh]

Hi

let's say a mistake happened, caused to brick the tablet which resulted in the need to flash the stock rom.
Is there a way to recover data from this device that was previously encrypted?
I can still see the files (at least on the SD-card) but I'm unable to open them after this event.
The data on the memory from the tablet itself is 'gone'.

I suppose that recovery was an option if it was NOT encrypted, yet impossible now?
