> reflashing every serial number in flash/EEPROM with 0x00.

It will be an amazing video, but good luck if the device in question has (very likely):

* a mask-ROM / OTP-ROM for a serial number - almost all microcontrollers and EEPROMs sold nowadays has at least one permanent and unchangable UUID for hardware tracking and DRM implementation (security-through-obscurity tricks to prevent rogue competitors from copying your firmware).

* "firmware read-protection" - which means the only way to dump the EEPROM is performing a full-chip erase and destroy the entire firmware, commonly used in embedded systems to stop rogue competitors from copying your firmware.

I just knew that RAM DIMMs usually have a 24 or 93 series chip on them, and figured that could be re-programmed (or replaced with a reprogrammable version if the existing chip is non-compliant).
