Downgrade from Oreo to Lollipop

[Stacey Beswick]

I want to downgrade my current android version as it is not connecting properly with my Garmin watch. I have exhausted all channels and advice and have come to realise that it is an oreo glitch. Any help or advice would be greatly appreciated

Downgrading your OS is not very easy. It will generally require you to root your device first after identifying whether there is a downloadable lollipop package available for your phone and carrier.

Failing that you need to find a ROM that is running lollipop for your device and even then there is no guarantee it will fix your problem.

It would be better to try and fix the issue. What is it that is going wrong?

The S7 was first released running Marshmallow, there apparently is no stock (official) ROM available for Lollipop.

Yea the answer is 'Rooting'.
But you must remember that rooted device can be hacked easily!

Maybe reset the Garmin? Gotta be able to factory reset Bluetooth devices too or they'd only be able to connect to one device.. ever. Reset your Garmin watch and try again..?? As for downgrading an Android OS? Don't do it, or you'll end up with a paperweight

Needs to be clarified that when flashing a stock ROM, that does not require rooting. That applies only with custom, third-party ROMs.
The issue in this instance is flashing an older version ROM is typically not recommended and will most likely be problematic.
If there is an actual, working Lollipop ROM for a Galaxy S7, please post where it can be obtained.

Would/could you explain what you mean by rooted and why it would make the phone easier to hack.

ROOTING means breaking your phonr bound
with rooting you can make ur device more faster and more slower change every software aspect of your device and make it be a real or a fake device and also with rooting hackers can also change your imei number and steal your info easily thays why is recommended not to put sensitive files in a rooted phone unless you are sure is protected with an antivirys that can block root access like mine

"Rooting" means modifying the phone software so that user-installed apps can be given administrator privileges ("root" is the name of the Linux administrator account, and Android is derived from Linux, hence the name). It allows you to modify things that you couldn't otherwise, but it also means that if you install some malware or your Google account is hacked and used to push malware to the phone that malware can also do the same.

Anyway, this is a distraction. Rooting by itself will not fix your problem. It will allow you to make changes to the system, but unless you know what the problem is and what needs changing that doesn't help you.

The picture you showed in the first post looks like a standard boilerplate "you are going to grant this app a lot of access, are you sure you want to do it?" warning. I presume you pressed "allow"? What exactly is the problem? If you explained what isn't working properly there's a chance that someone will have an idea.

Just want to emphasize what @Hadron stated, rooting is not going to fix your specific problem. A lot of people mistakenly assume rooting is a magical solution to fix any phone problem. It is not. So if you were to root your phone, that does not automatically give you the knowledge and skill set to do anything more than before. Playing with your phone's operating system and just randomly changing settings and deleting files 'might' work, but it's also a likely way to soft-brick your phone, and that forces you to flash your phone with a stock ROM to restore it into working condition again.
Don't worry about rooting your phone, instead focus on your actual problem.

Getting back to that Garmin watch issue, assuming you were using the standard Garmin Connect app:
https://play.google.com/store/apps/details?id=com.garmin.android.apps.connectmobile&hl=en_US
try this:
-- Go into your phone's Settings >> Apps menu, find the Garmin app, open it, tap on 'Force stop', then find 'Clear data', and then tap on 'Uninstall'
-- Reinstall the app from the Play Store, paying special attention on any permissions prompt(s) that may pop up during the install process, and see if pairing your phone and watch works out better this time.
Basically this is just re-doing the set up steps again from scratch. Perhaps the problem before was just some glitchy issue relative to some settings/config file prior to the Oreo upgrade.
