Since I haven't been following your work until now, I wanted to ask a possibly stupid question…Experimental new build with September 05th, 2021 security patches available
This build is to be considered alpha as it is lacking two patches from July as can be read on Gerrit. The patches from August and September have been included, but no updated patch level. It still reports July 5th, 2021, but as it is lacking the two patches from July from the "not implemented" section, it really should read June 05th. There are problems backporting these patches :-(
I've got it installed and running on my own device, but as of now only for a couple minutes.
As always, these builds don't contain any patches to closed source drivers, as those would have to be supplied by Lenovo. Who have long since stopped supporting this device.
Builds prior to May 8th, 2021 have been deleted from my dropbox to mitigate space constraints.
Use at your own risk!
Can't speak for navigation, but no problems using fingerprint lock on my end with this build
Requires nougat stock firmware

I don't use Google play services with this ROM, but I do use UnifiedNlp (com.google.android.gms, install via adb) in combination with WLAN Standortdienst (org.fitchyfamily.android.wifi_backend), GSM Standortdienst (org.fitchyfamily.android.gsmlocation) and Deja Vu (org.fitchyfamily.android.dejavu). Use SatStat (com.vonglasow.michael.satstat) to visualize the quality of the different provided locations.
