All tools support, the main problem you need to connect the correct pins.

Hi Finally I managed to remove the chip and programmed it . I could erase or write with medusa so i did it manually with EZP2010. I reprogramed the bios with 820-00244 MB91_0172_B00_no SN. But still stuck on apple logo at 99%

Origianlly I have replaced the CPU on this and after stuck on apple logo at99%. so i thought may be CPU recodnise code encrypted with bios. Any idea?
