[Xiaomi Mi 5 ROMs, Kernels, Recoveries, & Other Dev] i23098:
I've done it, after the reboot it's showing the lineage symbol boot animation for quite a while now :( how long is it normal to wait for the first boot? :confused: Getting a bit worried...

Did a logcat, it's in boot loop :(

I used lineage-17.1-20200621-nightly-gemini-signed.zip and open_gapps-arm64-10.0-nano-20200621.zip

Trying to do the upgrade steps again...

Did again the exact same steps and it seems to be working :victory: :fingers-crossed: Apps are still installed, haven't tested them yet but hopefully all is ok.

Thanks for the great work :highfive: :good:
