AVIC-MRZ99 Custom Firmware / Testmode
Hi,
sorry for posting in the wrong Subforum, but I didn't find a M-Series Subforum.
I bought a Pioneer Carrozzeria AVIC-MRZ99 on eBay.
It's a japanese Unit from an imported Car.
The Problem is, you can't change the language to english... you can't change it generally :/
Does anyone know if I can install another firmware to this device?
Maybe this device was sold in EU or USA with another Name.
Hard to find some infos about it, all in japanese language :/
I tried sev
Hi,
OK, here is the step-by-step manual:
Step 1: Take out the FW, see here
Step 2: Get the file named "PS140PLT.PRG". For RZ09 it is in folder NAVIVUP\AVICRZ09\PLATFORM\
Cut out 0x200 bytes from the start of the file: its header. I used the SFK-tool:
sfk195x64.exe partcopy PS140PLT.PRG -allfrom 0x200 output.nb0 -yes
When you need to extract file output.nb0 by the dumpromx.exe tool (easy to find it on this forum):
mkdir DUMP
dumpromx.exe -d DUMP -v -5 output.nb0 >
