        Revive/update keeps data, restore wipes data. In case of corruption or damaged SSD, data could already be gone anyway.

          I can't revive device. It does detect MacBook computer. Here are pictures. If I restore firmware, it'll wipe.

            What machine are you running the configurator software on? I had something similar with a 1932 that I restored.

            I know that Apple's information gives a minumum version of software of like Catalina or something similar, and says you can use any machine to run configurator on, but I found I needed a machine that had only USB-C ports, and ran the latest patched version of MacOS available for the machine I was using.

                  What is the history of the unit?

                  Inspect the board to see if there is any liquid damage or damaged parts.

                  20v is good for the adapter voltage. Be sure the adapter is the suitable power rating for use on this unit.

                  Measure the voltage to ground of ppbus_g3h.
