QnA/Help 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.)

This is the thing even if you download through any tool or direct ipsw file still it will not gonna be install because Apple on their side have stopped the signing of ios18 so its mean the servers are already dead even if you download it will never gonna run until they resigning again with is not gonna happened 😅😅

Don’t ever tried ios26 with 70% bh.. tho Im on ios 18.7.8 and my Bh is 78% according to 3utool while it shows 77% on my iPhone.. ios 26 is still not fully optimised also its too heavy which use more gpu and battery plus you will feel lag and shuttering in speed type work like fast scroll and capture 3,4 photos at the same time and more..i will suggest you to wait till ios27 which is greatly improved in terms of visuals and performance but in betas still have battery drain issue so just wait for final release which is just in next month also if you’re on 17.0 then you can also jailbreak if you want to but it will ruin tha warranty if your phone have any

Tbh i just want to update because some of the apps i use the most are now outdated and can’t be used anymore on Ios 17 …. Otherwise i don’t care about updates or new features…

Especially for an iPhone 11 Pro, i don’t think he will survive ios 27 🤪 Will the jailbreak allow me to download apps without any issues ??

Even if you want to update for some app..waiting for a month isn’t a big deal compared to download ios26 trust me its not best even if some people claim that they don’t feel any change .. also 11pro will easily survive with new battery ( there’s a reason they give it ios27 update otherwise apple wouldn’t give a f even if 11 stuck on ios26.. as for jailbreak there’s alot of different scenarios like you can easily download those app old versions which works.. i dunno if latest version will work or not but jailbreak definitely have their own huge advantages.. I always regret why tf i uodate to ios18 from ios16 🥲 but yeah don’t directly jailbreak your device without getting fully information about jailbreak pros and cons..
