M24SR corruption - Possible to restore to factory defaults?

I'm working on a project for simplifying commissioning of networks using NFC.

For a very basic demo I'm using an Arduino communicating over I²C and an NFC enabled smartphone.

Simply put: I read the old value from the NDEF file, next I write the new one. After this is done, the GPO_pin has gone high. Off this flank the Arduino gets an interrupt that reads out the new value over NFC. Now this works for a while, but after a while, I only get empty NDEF messages back over I²C. After this the smartphone doesn't even recognize the tag as an NFC Forum Type 4 tag anymore.

I'm lost on what can cause this corruption? And is there a possible way to fix this?
Any way would be greatly appreciated.
