I have this iMac Pro 2017 T2, 1 year agoo I tried to bypass it but I didn't figure it out to bypass it.
2 Days agoo I figure it out to remove account iC whithout test or try to power on my iMac and when I tried to power on I saw it do not power, I go to dfu tried restore/revive but it shows on display for 3 seconds Apple logo with almost full bar and on second macbook shows "Apple Controller" is not booted.

Now I made an mistake, I flashed Memory MX25L4006EZ with an bin founded here on forum "I MAC PRO 820-00967-09 ok.rar", that memory have only 512KB (I found too late it has only bios for USB3 & Disk) but that dump bin has 4MB (I saw too late),

I tried to flash back original backup which has 512KB (I made backup before to flash that 4MB bin) but same now, apple configurator shows only error 9 when try to restore and error 6 when try to revive (that errors are related with disk bios from that memory I think :(( ).
