My free advice:Thanks for the update and your work on this.
May I ask what you mean by updating to a caf compatible kernel Vs the original ROM you made?
Do you think in the future you can pass safetynet without magisk?
What's the best advice for updating from original ROM posted?
I wonder why they don't release an official ROM for our phone, I thought it was popular!
If you want a rom without SafetyNet issue, try its Pixelish sister. (Test return fail but it is because the path to Google PLay is bloqued, so no resukt, but it was OK 3 days ago)
You can dirty flash the rom in order to test.
-You are right, any OFFICIAL rom for this phone because it is no more popular. lol
