Doesnt activates swap codes on MST2

[Zassistent]

I have the next issue, have the Seat FR 2016 with MST2_EU_SE_ZR_P0245T, had installed Toolbox with cpu replacing with old GEM 3,5, then did applied patch Swap EL through toolbox, it says patch is ok and restart unit, after i did this the new swap codes doesnt become active, so i have decided to update head unit with , after update i did install the toolbox and applied patch again, and still nothing, no new FECs had added, so i have made dump, probably someone could help me to figure it out. In supported codes i see 00600900 and 00600800 that means Head unit supports carplay, but installed codes doesnt show that after patch proceed.

I have an Amundsen MIB2 in a 2020 Skoda Karoq. My unit had CarPlay and Android Auto from the beginning (these are probably the codes you provided) and I wanted to add those that can be installed. Before uploading the toolbox and after generating the SWAP code and uploading it by Car Scanner, the FEC codes appeared in the installed section but as invalid. Only after uploading the Toolbox and removing (code generator) invalid FC, I could suggest and upload them again and then they were valid and functionality appeared. Maybe you need to delete the invalid code at the beginning and add it again. After the whole operation, you need to reset the unit
