See if this helps. If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support If you see any error messages when you attempt to update again, provide those error messages. If you made a backup with iTunes, it seems strange that you appear to be trying to update directly from the iPhone. Connect it to the computer and iTunes and update that way.

Do you have the latest version of iTunes for the computer? Are you using a Windows machine or a Mac? Are you able to restore the device to factory, without using a backup? It sounds as if there may be a problem with your iTunes or corrupt data in your backup.

Again, it sounds as if there is an issue with your backup data. If you have attempted from more than one backup and it is not working, then you are going to have to restore the device to factory and set it up as new, without using a backup. From there, you will have to add your content back manually. If your contacts and calendar are in iCloud, just sign back into that iCloud account and turn that back on. Any iTunes content can be downloaded again from the stores.

It is either your content or your device. There really is no other way to troubleshoot it from here. If the backup keeps failing but you are able to set the device up as new, I would have to point at the backups. Something is preventing them from completing. The link I provided you at first is the only one that addresses the inability to restore the phone. And since you do not report any error numbers that appear when the restore fails, there is no other troubleshooting you can try.

I found an old iPhone 6 16GB with iOS 12.4.3 - do back-up restore with my old back-up (which did not work on my iPhone 7) - and it work.

My last back-up do not work, because my old phone is 256GB and no free space on iPhone6

Try to recover to new iOS 13.4.1 on my iPhone 7 and after transfer data from iPhone6 via Bluetooth - same story iPhone reboot and freeze ~~99% (of progress bar)
