i solder eeprom on adaptor board

any help? could it be bad eeprom?
is there any guide for this?

u did verify data after reading eprom?

Is possible BAD eprom.

Reading all 0000 seems like no 5 volts to the eep. Check for the voltage solely at the IC pin 8 while reading to see if it present!

post a pic of the eeprom on the board

Here is EEPROM on board.
if i filp eeprom the other way, i get read error.

i did not have time to make measurements, can u assume anything from 'voltmeter' tab on screenshot?
thank you guys for your help.
