It’s what they do with most issues
Thanks for that snippet of information, as this was my first dealing direct with DJI repair I wasn’t aware of this.
DJI repackage and heat shrink all their refurbs too. Much like Apple do.
Moved your post to an existing thread on this error code.
Out of interest why don’t you let iOS update automatically? And how do you do it manually - via PC?
iOS does not remove the old version, it just writes the new version over the top.
If I want to update to a newer version I’ll uninstall the old version and do a soft reset to get rid of all the left behinds , then just add the new version through the App Store
