No worries, recovery is also updated with this package.
Managed to make it work. Looks like there was some issue with mind gapps. Did a fresh install again with nikgapps stock SL package and its working flawlessly now.
All went well. (Had to just ignore error warnings) Thank you very much.
The antenna for NFC is usually in the camera part of the smartphone (because of the aluminum back cover)Have to correct my initial statement: It works! But the "reading zone" of the OnePlus 5 is extremely narrow compared to my currently used OnePlus 7T. For the OnePlus 5, you have to use the very top back part and be a bit patient.
Thank you to the other two positive observations making me doubt my initial test!
And no, issue 1 is NOT gone.I have two observations which are odd but not really an issue:
ADDITION 26.5.: Just wanted to add two more pictures of issue 1 ... but it is gone. Maybe linked to the fact that I deactivated the developer options incl. USB debug mode while it was hidden before I did so. New to me but nice feature - developer options are re-hidden upon deactivating them. Just the right thing for a phone that is supposed to go to a "regular user".
- The battery usage trend has gaps (the previous day) or missing that one if running less than two days. Below is an example with the gap (left) and without (right) which you get after reboot. I resolved the gap or missing part now reproducible twice by reboot.
- Is it normal that the USB debug mode is active in this build? Receiving the notification when connecting to a PC. I haven't changed it for sure since clean flash the official build incl. recovery as I don't have developer options unlocked. And I can't recall having had developer options unlocked and active (required for activating USB debug mode) on the unofficial LOS 19.1 before. And it wouldn't be persistent across clean flash, right?
