Magisk will hide rooted status from specified apps; the author always
seems to be one step ahead of Safetynet (the part of the OS that detects
root) but no guarantee that will continue for ever ...

Isn't the real question not how to do it and get away with it under
normal circumstances but whether, if your mobile banking goes itspu
and you lose all your dosh, your bank will still pay you compo?

In which case, go back to them and get one that does work.

I don't think you need to root a phone to replace the OS, just unlock
the bootloader.

Ditto in that I'm an ex-IT guy and the Android and Linux guys
sometimes may as well be speaking Klingon and I wonder how they got to
that point.

Of course it's these same guys that write these systems which probably
explains a lot. I did root an old Android 4 phone which allowed me to
free up memory so I could actually run some apps that I wanted,
nothing spectacular. It was no big deal but if I'd lost the phone it
wouldn't have mattered that much.

But if you don't want to fiddle then you are stuck with standard fare
so just go back to factory settings. If you got your apps from
playstore I suspect they'll re-install anyway.

Back in the days of android 2.x and to a lesser degree 4.x I did put 3rd
party firmware on my phones/tablets, to get round restrictions of under
1GB flash and 1GB ram, but I haven't bothered recently. I generally
give a big fat warning when pointing people towards XDA.

Why do you want to root it?

You can root the existing Touchwiz (Android 6) install:
https://www.youtube.com/watch?v=k2oOvf5tOCY

but of itself it doesn't change very much, it just means you can run some
apps that require root. It also makes your phone more vulnerable if you
give root to apps you don't trust.

If you're into custom ROMs these work reasonably well on my Note 4:
https://forum.xda-developers.com/not...-16-0-t3900807
(I most recently tried the 2019-10-17 build - there are definitely better
and worse builds - read the end of the thread for what people recommend)
https://forum.xda-developers.com/not...7-0-0-t3899186
(2019-04-24 build)

and this video gives the procedu
https://www.youtube.com/watch?v=hQoHApohbDk

(with a different ROM, but that's just flashing a different downloaded .zip file)

The main annoying bit is installing TWRP which you only do once, once that's
done it's fairly simple to flash a new ROM from an SD card.

Be aware that generally it's a good idea to wipe data before reflashing, so
you might have to reload apps etc. There are backup apps like
TitaniumBackup and Migrate to help with that.

It's probably better not to do it to your daily driver unless you have
another phone you can use if you mess up. Generally, a full wipe and
reinstall fixes most issues, but no good if you miss that urgent call while
doing so.

I'm considering whether it's worth the time/pain/risk of rooting because
I've read that it allows the bloat-ware to be removed and that some ROMs
are faster than the standard Samsung ROM - but I'm in the difficult
situation of not knowing what I don't know about the subject. The more I
delve, the more I'm tempted not to bother.

That is the question. For most people they have no requirment to have
a rooted phone. Changing or upgrading the ROM however can give
benefits like giving life back to an old phone/tablet.

It seems complex but it's not really. A lot of the apparent
complexity comes from the fact that the software tools and version(s)
of the firmware(s) required vary with the hardware you are trying to
upgrade.

Basically you use Odin on a PC to replace the phones bootloader with
TWRP (device specific) over a USB connection. Then boot into TWRP on
the phone to replace the ROM (device specific) from an SD card in the
phone.

In summary, you need:

Odin, to flash the bootloader:
https://odindownload.com/
if you aren't on Windows there's also Heimdall:
https://glassechidna.com.au/heimdall/

A version of TWRP for your phone. I assume you have SM-N910F model (that's
the European Note 4, with a Qualcomm Snapdragon CPU):
https://twrp.me/samsung/samsunggalaxynote4qualcomm.html

A ROM .zip file (see the XDA links I posted earlier).
It seems the ResurrectionRemix builds work slightly better - eg
RR-P-v7.0.2-20190920-trlte-Official.zip
from
https://forum.xda-developers.com/not...7-0-0-t3899186

If you want the Google apps (Maps, Play Store, etc) you need Opengapps
https://opengapps.org/
Pick 'ARM', the version of Android you're using (9 probably), 'nano' - this
will install the Play Store, and you can then install whatever apps you
want when you've set up your Google account.

If you want root (you probably don't, to begin with), you need Magisk:
https://forum.xda-developers.com/app...mless-t3473445

The procedure is:
1. Install Odin on a Windows machine
2. Use Odin to flash TWRP (requires holding Power+Home+VolumeDown buttons at
power up to enter download mode, then connect to PC via a USB cable)
3. Put RR, Magisk and OpenGapps .zip files onto a micro SD card
4. Boot into TWRP (from off, hold Power+Home+VolumeUp)
5. Wipe system partition and cache via the touch menus
6. Install the ROM .zip then the Gapps and Magisk .zips via the touch menus
7. Reboot into your new OS (first boot may take a while)
8. Set up your 'new' phone

Like anything, it's a bit slower the first time but a lot quicker second
time around, especially since you don't need steps 1-2 again (although you
can use Odin to reinstall the Samsung firmware[1] if you don't like your custom
ROM). It's worth following a video on how to use Odin since the UI isn't
terribly obvious (it's an internal Samsung tool that's leaked onto the net).

Once you've done this, it's like having a new phone for about 15 mins work.
