At first tried connecting the phone to a MacBook (Big Sur OS) for the restore, but for some reason the Finder wouldn't recognize the phone. So instead, I connected the phone (while in Recovery Mode) to an iMac running iTunes in El Capitan. This time the computer recognized the phone, downloaded the restore software package, "extracted" the software, started to install it, and then -- got the error message in the title: "The iPhone 'iPhone' could not be restored. An unknown error occurred (10)."
Subsequently, also as noted in the title, when I now simply turn on the iPhone, it now automatically goes into the "Recovery Mode" screen, even if I simply press the power button without doing the up/down volume button trick.
Problem is, the Big Sur MacBook still won't recognize the existence of the phone, and the El Capitan iMac can't update it, and the phone's iOS is apparently messed up due to being only partly installed, so all I can get is the Recovery mode screen, so I can't restore just using the iPhone itself.
Well, I finally got the iPhone restored, but only after multiple attempts, restarts, and aborted software downloads and installations. Even though I was ultimately successful, I still don't know what the problem was. I disabled all security software, was using Apple cables and connectors, had the latest updated version of MacOS running on the computer, etc. etc., but for some reason the connection to the iPhone was balky and inconsistent, the software download kept getting interrupted and stalling, the Finder kept freezing up, the extraction and installing of the iOS kept quitting unexpectedly, and so on. I just kept trying over and over for several hours, and EVENTUALLY it all got completed and the iPhone's iOS was restored. So, thank you, although I'll never really know what the actual problem was.
If you see error 10, your iOS device might have a newer version of iOS than is supported by your computer. You'll need to update the software on your Mac or iTunes on Windows before you can update or restore your iOS device.
Thanks for the reply and the video, but it doesn't solve my problem. As I said, at first my MacBook with Big Sur wouldn't even recognize the existence of the iPhone in the Finder. I finally got past that problem by fiddling around with different cables, so now the Big Sur Finder "sees" the iPhone. But now when I click on the "Restore IPhone" button, literally nothing happens. So I'm still stuck. In fact, the Finder window refers to the iPhone as "iOS device," and can't even tell if it's an iPhone or something else -- the phone's iOS must be completely corrupted by now, due to the earlier incomplete attempt at restoring it. So -- still looking for a solution.
Finder will not be able to identify the type of device until it has be restored. Yes, iOS on the phone is corrupted, but that is irrelevant, because restoring does not require that iOS even exist on the phone. It uses a low level ROM kernel to restore.

The backup and restore scenarios are specific to enrollments via Apple Automated Device Enrollment. For information about how to back up, restore, and transfer data for an Apple device, see the following Apple Support documentation:
Device-to-device migration, an option that appears on the Quick Start screen after resetting an iOS device, isn't supported with Apple Business Manager. Quick Start occurs before a Wi-Fi connection is established on the device and before the Apple Business Manager profile downloads. As a result, the Quick Start screen can't be hidden via Apple Business Manager.
If you're using the Microsoft Authenticator app, it's also important to back up your credentials and accounts. For more information, see Back up and recover account credentials in the Authenticator app.
Restoring a backup is only possible during Apple Setup Assistant. This backup is a one-time opportunity. Consider the information in this section to help you prepare and support device users restoring their content from an iCloud or iTunes backup.
Linking an Apple ID in device settings post-setup isn't the same as restoring a backup. While linking the Apple ID does link files and documents, it doesn't typically restore any user data and preferences such as wallpaper, widgets, installed apps, and user preferences. Only a limited set of data, such as iCloud Photo Library and messages, can be restored.
To avoid enrollment issues, tell device users that they shouldn't back up their device when it's enrolled. It's important to avoid backup and restore activities that could impact the management profile and related certificates.
Consider the amount of time elapsed since the last backup, and how the device would be impacted if restored to that time. These scenarios might be less common, but they are worth being aware of, especially if the backup being restored isn't recent:
Typically the MDM enrollment state at the time of backup isn't of any special significance. However, in a migration scenario where you're moving from one MDM vendor to another, it's important to be aware of the device's MDM enrollment state so as not to restore an old management profile. The following steps outline the sequence of events that lead to this scenario and the failed outcome:
Company Portal notifies the user of this conflict by explaining that the new MDM payload doesn't match the old payload. To remediate this error, the device user must remove the management profile belonging to MDM vendor A, and then re-enroll in Company Portal. You can expect the same behavior and outcome when migrating from one Intune tenant to another Intune tenant.
