Is it possible to upgrade from (latest) official nightly v15.1 to official nightly v16 without wiping data?
I've tried an early build which in the end forced me to reinstall everything (because of bootloop) and would like to avoid doing that over again.
TIA.
In recovery mode :
- install the highly recommended TWRP (https://androidfilehost.com/?fid=1395089523397907195)
- boot to recovery
- wipe the two caches and format system
- install lineage-16.0-20190306-nightly-oneplus3-signed.zip, GApp and then SU addon (if you want)
- boot to system, wait and enjoy ... Perhaps!
