Since I installed CM14.1 on my OP3, many things have changed.
Cyanogen shut down all services and LineageOS development started.
Today I wanted to get a refresh on my system, so I tried to flash the new LineageOS Nightly build, but I got into some problems.
First of all I installed the latest TWRP recovery available here.
Then I tried to install the latest nightly build from the Lineage OS official page, but I got always an error like:
Error-Message: assert failed: oppo.verify_trustzone(“TZ.BF.4.0.1-85373”) == “1”
Updater process ended with ERROR: 7
After some googling and 1 hour spent trying different solutions I got to the right solution:
- install original Oxygen 4.0.3 image for OP3 from oneplus.net site
- reboot and load OxygenOS (without doing all the first configuration process)
- reboot again to recovery
- install LineageOS image
- install GApps for 7.1.1
- reboot and woila!
Now I can run LineageOS on my OnePlus3 whithout any issue!
