Istep upgrade - non OEM FSC rejected - solved

[prisco1975]

Hello all.
Time ago I enabled carplay, full screen, apps, lifetime maps, etc via Feature Installer on my oem NBT evo ID5

Last days I had Istep upgraded by delear (due a recent recall).
Delear asked me to confirm the upgrade and sayd I would have problems with options I activated because non OEM; I sayd yes thiking operation wiped the fake FSCs and I could restore it.

My car is back and navigation won't start (delear told me)
On ISTA all fake FSCs are still there and "rejected".

How to proceed to do a correct job?
a - simply use F.I. apply the patch to re-enabling carplay & co;
b - use F.I. to revert to the orginal situation and then apply the patch?
c - delete the fake FSCs before via Esys in some way and then use F.I.
d - revert to original using my OEM FSCs repair pack?

All informations will be appreciate

Just use feature installer and install patch again

Just use feature installer and install patch again

Worked like a charm.

Used FI again and all FSC were accepted.
Thank you.
