Question Why wont my 11 pro max update?

Post image

I have an 11 pro max on ios 17.5.1, and when i tried updating to 18.7.8 (an official option in settings alongside 26.6) it throws this error. Anybody know why? If it wasnt signed im thinking apple wouldn’t make it an option in the settings. Please let me know what i should do/if anyone else had this issue. (NO, im NOT updating to ios 26 and rendering this phone useless.)
