Looking for MR5.3

Looking for MR5.3, someone that may help? It has to be 020

[580-Gabor]

There is two MR5.3:
R6C.298.02 from Jul.2005, FVN5308E
and
R6C.303.01 from Oct.2005, FVN5308F

FW for both was: 5431.
It is pre CPS plus, so you need the .z19 firmware file and it is model specific.
There is different .z19 FW file for the MTH800 and for the MTP850 etc.
It is very old and TEA2 too, so nearliy inpossible to find.
Upgarde your terminal to CPS Plus compatible FW and done.

Is there newer than R13.020.8467?
