Default [Q] MTN Steppa - BYD SP355AWG - Firmware Needed

Hi Everyone,

Desperately looking for the firmware for the MTN STEPPA (BYD SP355AWG) phone.
The guys at the MTN repair center aren't very helpful, only saying that the cannot/are not allowed give it to the general public/customers/owners of the MTN Steppa (BYD SP355AWG) phones.

At any rate, any one who might have any idea as to where/how obtain this firmware somewhere, would be invaluably appreciated..
Many Many Tx.
