Question on firmware upgrade

Hi there,
maybe an old question.
Just got my 4120B with A102 firmware and want to try the N0AD firmware which provides the autobitsetting. So my question is that if the firmware upgrade is reversible, like, I flash the N0AD , then if I can switch back to A102, 'cause I don’t wanna void the warranty.
Thank you.


I can’t see any reason why you can’t do this. As was already mentioned in another thread you can flash many times, just make sure you take the usual precautions.

Like drives from other manufacturers, firmware flashing is safe in most situations. It’s easy to switch between A102 and N0AD many times.
