Hi everyone, I have a Seat Leon III 5F (2016) with a Harman MIB2 High system (ref.: 5F0 035 043, hardware H28.28.210_HIGH2_EU). Original factory firmware: MHI2_ER_SKG11_P0257_MU0123 With this firmware, everything worked perfectly: Seat skin/branding, OPS/PDC visual display, ringtones, navigation, and all Seat-specific functions. After installing SKG11_K3343_1_AIO_MU1433: All seat configurations were replaced by Skoda default settings. I lost: OPS/PDC visual display (parking sensor beeps still work) Navigation (no map database recognized) Phone ringtones Seat skin replaced by Skoda skin Android Auto not working (SmartLink error) What I've tried: Added FEC code 0730004c to addFecs.txt ✓ SVM fix via mib_aio ✓ Navigation coding = ON, EU ✓ GPS antenna OK (3D fix confirmed) ✓ Brand = Seat confirmed in GEM ✓ Module 76 coding correct for OPS ✓ 5F Long Coding: 04 73 80 01 FF 0A 00 00 11 11 00 01 00 08 08 00 2F 01 01 C4 01 20 01 07 5E My questions: Is it safe to install firmware SEG11_P4709_1_AIO_MU1447 on my SKG11 head unit to restore the original Seat configuration? I read that some bootloaders only accept Skoda firmware. If SEG11 is too risky, can I first revert to SKG11_P2104_MU0318 (an older bootloader) and then try SEG11? Is there another way to restore the Seat configuration (OPS, Android Auto, ringtones) while staying on SKG11_K3343? Thanks
