BLUF: This RR version is my daily driver from now on. Running simply excellently without any issues. Thanks very much to rodman01 and @p.a.n. for a fantastic job and ROM. Well done!:good:

Clean flash. Wiped dalvik, cache, system and data; flashed RR. Booted into system. Back into TWRP and flashed Nanomod microG; booted into system. Back to TWRP. Flashed Nanomod patcher. Flashed the very small update.zip created with Titanium Backup Pro (TB) that only contained three essential applications I wanted to have installed from the very beginning e.g. SD Maid Pro and AFWall+. Flashed Greenify4Magisk. Booted back into system.

The very first reboot (after flashing of RR) took slightly longer as expected. All other reboots without any issues; no bootloops etc. Baseband (XXUFOA1) and SIM available from the very beginning. No SIM lock.

In the next step, I manually reestablished all my desired RR settings (what obviously took quite a while as usually after a clean installation). Set SELinux to permissive/moderate (was at strict after initial flash of RR). Restored my contacts and calendar entries from TB. Restore my AFWall+ settings and rules. Activated AdAway with my black and white lists. Modified the APNs to my need. Connected to home network via WiFi, and setup the fixed IP address and DNS servers. Created my Google account. Restored all user applications by TB. Modified a few kernel settings by Kernel Adiutor Pro e.g. governor to zzmoove, max CPU to 1000 etc. Still require to set the profile to battery yank. Via MyAndroidTools Pro went through all services and broadcast receivers of all user applications and a few designated system application (e.g. Google Play Store) and disabled the services and receivers of my desire. Rechecked with SD Maid Pro that auto-start at boot was disabled for dedicated applications.

Settings of the hardware buttons stick and work (see screenshot).

Radio/baseband/modem/RIL working. Good and very clear phone calls; mobile network working (was only able to test this on 2G due to the rural environment); SMS working. MMS not (yet) tested.

EDIT (2017-07-10): Today, I was positively able to also test 3G/4G mobile data connection. All working as advertised.

No issues with the dialer UI; working as advertised (see screenshot).

GPS working, got the fix extremely fast.

Magnetic compass now working perfectly (thanks very much for that fix).

Bluetooth working.

Good charging times.

Finally, and please refer to the attached BBS idle dump (nearly idle but that makes the result even better) and enjoy with me a battery drainage of only 0.4% per hour. The ROM inherent kernel seems to be great; really excellent kernel wakelocks. Currently no need for me to change to a custom kernel.

What wasn't tested:

Due to the large amount of customisation features of RR certainly some settings that I haven't used yet and that I won't use.

Some of the RR inherent applications like Browser, Email, SMS/MMS, Camera, file manager, calculator, Pixel launcher, Trebuchet, weather provider and weather service. I freeze these items from the very beginning and am using custom alternatives.

Maybe I forgot or missed something above? Just let me know.

EDIT: On our second i9305, dirty flashed RR-N-v5.8.3-20170706-i9305-Official over RR-N-v5.8.3-20170605-i9305-Official-HWC. No issues at all. If I'd known it would have saved me a bit of time.
