Unable to read Eeprom out of circuit

Thanks to your amazing piece of code I managed to successfully read the Eeprom of a v1 Xbox that was and still is corrupted. Checked it first with the LiveInfo program and then via hexeditor. I have another Xbox that has a dead PSU and I attempted to read the Eeprom content in order to flash it into the corrupted Eeprom, effectively cloning the psu faulty Xbox. No matter what I did I was unable to read its Eeprom content since the console does not power on, even with a known working psu. I desoldered the good Eeprom which is a CAT24WC02J, check the pinout diagram and wired it accordingly to the Arduino Pro Micro, Micro pin 2 to pin 5 of Eeprom, Micro pin 3 to pin 6 of Eeprom, Micro pin GND to pin 4 of Eeprom and Micro pin VCC to pin 8 of Eeprom. Every time I run the ArduinoProm.py it gives a read error and says to check connections, despite the fact that I managed to successfully read the Eeprom chip content on the first Eeprom corrupted Xbox using the LPC port. Also tried to hook up the Eeprom chip, pin 8 VCC to external 5v line coming from a spliced USB cable connected to huawei 5v smartphone PSU that is known to work, just to see if perhaps the Micro board was not able to supply the Eeprom enough juice. Well... Same result, any help will be greatly appreciated
