[Q] Restoring to iOS 10.3.3 while preserving data

Here are some things to know about backups:
-They backup your installed apps and all of their data.
-Some information stored in iCloud can be restored without a backup.
-You can only restore backups from certain versions (generally older ones) and you cannot restore an iOS 11 backup to iOS 10.
If you want to keep at least most of your information you'll need an iOS 10 backup.
If you have an iTunes backup it can restore apps without redownloading, however they removed this feature in the latest version of iTunes.
Why don’t you back it up on your laptop? And while setting it up as a new device you can choose to install the apps from iTunes.
really?!
If you’re talking about the app memory usage on your device then that includes app specific downloaded file as well, which may not be the actual app code.
Eg : the memory usage of Spotify would include the downloaded tracks for offline viewing as well. When you back up the app, it doesn’t include those files.
You'll need itunes on a MAC or PC for this
1. Download the full ipsw for your phone (google is your friend)
2. Create a local backup in itunes that is encrpyted
3. While holding shift (on PC, not sure what key on mac) click update, and a window will open asking for the IPSW
4. Leave the iphone connected and than restore the local backup from itunes
You'll need to setup touch ID again, but you'll be back on the iOS version of your choice.
EDIT: Misread the post, I stand corrected, you cannot restore backups from difference versions of iOS

Yep, they only want apps managed through the App Store now.Wowreally?!
You're right, the apps themselves are separate from the backup. Only their data is stored. iTunes used to store the app files separately but this was removed.
You don't have to set everything up from scratch if you've got the right backup file. Unless things have changed, you can't restore a backup that was created with a later version of iOS to a device running an earlier version. And, in general, newer backups overwrite older backups in iTunes. Also IIRC, the only really complete backup is an encrypted local backup, which stores most but not all app data.
So what I believe you would need is an archived, encrypted local backup made while the machine was on iOS 10.x. Restore the device using the 10.3.3 .ipsw file (before Apple stops signing it), then restore an encrypted local backup. I've done this twice in a week with my two iPads and it works.
If you don't have a recent backup, Whatsapp can be backed up and restored from iCloud individually, so that shouldn't be a problem: https://faq.whatsapp.com/en/iphone/20888066
