5D4 ERR 70 but now working again.

Hi all.

I was trying to update the firmware on my 400 DO II and when i clicked on updating it, it would just clean the sensor instead of updating. I tried it a couple of times with no luck. But randomly I got a ERROR 70 on my 5D4 when i tried to turn it on. Tried it again and kept getting it.

But I removed the battery and put it in again and now the camera started back up and working normally now.

Is this something I should be worried about going forward? Or just a random event?

Thanks
