Firmware 1.06 and testmode/developer mode codes

Recommended Posts

Looking to see why the testmode key and/or developdbg on doesn't work with firmware 1.06.  I need to use testmode_A key but the headunit doesn't recognize the file, doesn't enter testmode and just says "file is undreadable".

anything i can do to work around this?b i am attempting to access test mode on pioneer nex 4201 with firmware 1.06 installed .  Is there a way to roll back the software to 1.05?
