Need intermediate firmware links for Octavia Mk4 (MEN3_EU_SK38X_P0393L to P3265L)

Hello everyone,

I have a June 2021 Skoda Octavia Mk4 (A8) equipped with the 8.25-inch MIB3 Swing/Bolero infotainment unit.

My current software train version is: MEN3_EU_SK38X_P0393L (MU 1315). As you know, this early version is unstable.

I managed to find the final target firmware MEN3_EU_SK38X_P3265L (MU 1805), but I know that updating directly from P0393L to P3265L is extremely dangerous and can brick the unit.

To safely perform the step-by-step update path, I urgently need the intermediate firmware versions:

- MEN3_EU_SK38X_P1560L (MU 1560)

- MEN3_EU_SK38X_P2340L (MU 1790)

Could anyone please share valid download links (Mega, Google Drive, OneDrive, etc.) for these files?

Thank you very much in advance for your help!
