How do i remove the writeprotection on my Osmo?

There is no write protection pin on  micro SD card /TF card. If the writeprotection appears when you open it on your PC, please check if the SD card reader wirte protection is on or not.  The SD card reader may have the write protection setting. Or can you provide a photo or screen shot so I can locate the problem. Thanks!

I have a MacBook Pro and any microSD card I mount in the SD slot using an SD adapter is always write protected for some reason.  Perhaps your issue is similar?  If I use a card reader then I can write to the microSD card.

Yes, because the SD card adapter have a write protection switch, you can try to switch it to the other side and see if the protection disappear.
