Updating macOS on restored Intel MBP keeps failing

Hi,

I have a 2019 Intel MBP which had some stability issues (crashed sometimes), so I tried to update to macOS Sequoia (from Sonoma). That did not work so I reset the MBP via DFU and another Mac. Then I was able to successfully install macOS Catalina (the original version the MBP was shipped with). However, now I cannot update to any other macOS from there. Tried Ventura, Sonoma and Sequoia and all installers return errors:

I also tried to update by launching the Sequoia installer via internet recovery (reboot and press Option + Cmd + R) which also resulted in the same error.

Does anyone have an idea what else I could try?

MacBook Pro (2017 – 2020)

FWIW, if it were mine, I would make sure I had a Time Machine backup, boot into Recovery Mode, erase the drive using Disk Utility, then reinstall the OS from recovery. You can then use Migration Assistant to restore your data.

There are some, who claim signing out of " Find My " application will work

While some others suggest signing out of " iCloud " will work

And still more, suggest using an Ethernet Connection versus wifi will make the upGrades work

Then there is always possible restart in Recovery Mode and choose " install macOS " may or may not present some of the more recent versions of macOS this computer qualifies to run

That last option is a bit of a Good Luck just what version will or will not be offered

I only have created a local account on the MBP and not connected any online accounts. Also I used Ethernet connection to download the updates. I also tried installation via recovery mode and erasing the disk first, with the same result as stated above.
