I really don’t know why the /e/ team can’t give a list of the device who need to go back to stock ROM.
It would be much appreciated.
From what I understand, this is especially true for recent phones with manufacturer updates offering the android version (let’s say T) in Stock ROM. But in fact I don’t really know…
I regard this as “generic” advice. Yours is a 2019 Moto. Hopefully when you first installed /e/OS you ensured you were on the latest vendor firmware release … so I would assume you should have no further need for any further use of stock ROM for an upgrade. Personal judgement only.
As firmware is released for say a 2 year old device, the person who built with the latest available firmware cannot say for certain at that point that firmware upgrades have ceased.
We can take as guide that most manufacturers (notably different Fairphone) only generally continue firmware upgrades for 18 months to 3 years. There will be many exclusions from this over simplification
We each have to do research the latest vendor firmware upgrade before installing /e/OS on our device.
What if users were to share the Vendor SPL (security patch level) of their researched and correctly running /e/OS device. Settings > About phone > Android version > Vendor Security Patch Level.
