Hi, I have a problem with an iPhone SE. After a restart, it started prompting me with an activation error and it wants to update to the newest iOS version but it has not enough free space to do so. Now I can’t get into the phone to free up space and it won’t start without an update. When connecting to iTunes all the relevant options are greyed out.
There is a free program called 3Utools. It has an activation option there. Also you might be able to clear some space. But remember if you try an update it will likely give you an error 26 which is unrecoverable and you will have to restore losing all your data.
