PS2 psx desr firmware update

[knikio]

hello
Is it possible to update the firmware of my PSX In case I don't have an original disc.
I managed to download this file "DESR-7000-DESR-5000-DESR-7100-DESR-5100 Senyou - PSX Update Disc Ver. 1.31 (Japan)" and I want to know if it is possible to use this file for updating the firmware.

thanks

Two options

1. MechaPWN and Burnt disc masterpatched.
2. Cr4ck3d installed, wich runs from HDD.
