upgrade to any release except mojave impossible after disc change

crwdns2934249:0crwdne2934249:0:

Hi, how can I upgrade to Sequoia or previous releases an A2115 / 2020 iMac?

I have made this upgrade several times on iMacs easily, but this time I'm getting crazy about this operation.

The new drive is an 870 QVO by Samsung and I have previously split the Fusion drive. (prev. configuration 1TB seagate Hd + 28Gb apple ssd)

I've tried with any OS installers, even with Open Core, but I get the same result: Impossible to verfy the installer, or sometimes installer corrupted...

What can I do? Thanks...
