:::info There are following known ways to pass the CID check:\na. Find some old Samsung EVO/EVO+ SD card and change the CID like described here.\nb. Order "Custom CID" SD card from AliExpress. Note: those cards are low quality and die soon.
c. Patch CID check ("MIBST" PNM) in CPU_HMI.EXE.
::: 2. To have FECs 00040100 (Navigation) and 022000ee (lifetime EU maps) as allowed in "Activation keys" of RED menu:
:::info You can install Actvator by Enthusiast to enable all FECs
