Can it be we forgetto unplug the battery when swapping the SSDs? It's maybe SSD compatibility? ADATA SU650 not found but is OK in a 2012 A1278..same any other brands...can be something with the EFI? I tried everything, CD bay no luck ... no option at boot for recovery or terminal...stumped. hopefully bumping this someone can shine more light and a fix?

Oh, it was fine before as I had it dosdude patched to catalina... but the SSD was just 100gb and old, needed a larger SSD... I tried with a blank formatted new SSD in APFS and Journaled, and again with a regular catalina install, still the white screen or a no entry sign... EFI maybe? But how to flash that with no way to get to recovery?

Also, my boot EFI is greyed out... there is power getting to the SSD or a HDD so cable is not the issue, Must be the EFI is corrupted? But how can I fresh install that when if I try to use a Snow Leopard DVD nothing happens or a USB of High Sierra the same (No entry sign).... no terminal, no recovery, no options.....
