Mitsubishi L200 2015 neef DPF off and how to write ECU

[fluorescent]

Hi all have a good day .
Need some help here,have a Mitsubishi L200 2015 with dpf problem, 1L oil level increase in one weak by bad regeneration.
So i decide to make DPF off.I have Galletto 4 reworked by myself until now all is fine.
MY ecu info:

DENSO 4D56
1860C184
MA275700-3672
MCU inside is R4F70580SV
car year 2015

I manage to read ecu by RENESAS_JTAG but choosing MITSUBISHI RA6 4N1X:
all read 100%.
Now i want to know how i write back the modified file?
I see in that manual RENESAS_TOOL BOOT my MCU is listed.
Can i give a try or i can get a broken ECU?
Do i need to make checksum calc? and ho i do it?
I see tha dpf remover software support my ecu and recognize my file, but i am not sure is ok this soft, i see that software is not so good.
Here my ori file readed by jtag_renesas, is some good soul make DPF OFF and calculate checksum.
