[mojoe]

Hello,

Please advise hot to update my Huawei P10 Plus VKY-L09CO2B102 to OREO.

Currently Stock Rooted EMUI 5.1 - Android 7.0 - TWRP 3.1.0-0 - root Superuser Koushik.

Did not update since purchase in June 2017. No security updates as well. I deactivated the updater.

Now I would like to update to OREO, update TWRP, and root.

Please advice how to.
