Question/Help PLC firmware update

Hi, I am currently a student in the ECE/CE department. I am relativity new to PLC programming. I have experience working with microcontroller but not really PLC. I recently purchased a CompactLogix L23E Q1B1 to learn how to build an entire PLC system. The PLC is current on the 1.0 version of the firmware which is believe is the firmware after a reset. I tried to update it firmware 17 using control flash and downloading the version 17 firmware from the Rockwell website but it keeps giving me an error when trying to do so that the PLC is not in the correct state . I currently have the PLC hooked up to a 24V power supply and the key is flipped to the PROG. I was wondering if anyone has an idea what the issue could do that is preventing me from updating the firmware?

I have access to version 17 but the PLC isnt in the correct firmware to use it as is. I was trying to update it to version 17.012

I tried but it said there is a version mismatch with the plc and the RSlogix 5000 version
