Software token?

[shatty]

Just got G87 2024. Tried to use ista to upgrade ecus and modules to latest istep.  Saying it needs software tokens?  Read that ista needs access to bmw to pull certificates to talk to car now. Any fix for this?  Also can I open flaps with any software besides BimmerLink?  It says function not available when I tried. Can esys or ista open them?  I saw in insta that u can put them in install mode but doesn’t open all the way. Was going to do a fuse  pull.
