I have received a new SL300 radio from Motorola and tried to downgrade the firmware to v2.09 in order to be able to program it using CPS v16. The problem is that v16 cannot access the radio, and I get the error Codeplug Not Supported, so I cannot do the Device > Upgrade procedure.
I also tried by setting the radio into flashzap mode by pressing PTT and side button on power up, the screen says "BOOT", but the CPS 16 can still not see the radio (no valid device error).
Radio is only readable with CPS v2.110.120.0, but not with earlier V2 versions.
BTW I installed the MOTOTRBO_SL_R0209000001_140013_Portable.exe file before attempting the FW downgrade so the necessary files would be available to the CPS.
What am I doing wrong? I'm pretty new to FW changes.
Or did Motorola close the possibility of downgrading for newer production radios to use CPS 16?
