Best way to un-jailbreak?

[spinedoc77]

Best way to un-jailbreak a 6s+? I was thinking of just updating to 9.1, will that clear jailbreak or will I have issues doing it that way. I'd rather avoid losing apps, or having to set up my phone all over again.

Yep just update with iTunes.

The above poster is wrong.... Backup in itunes, restore to 9.1, then restore to the backup. Updating messes up a jailbroken device and usually doesnt even go through.

I've always updated and never had issues. Do an update first, but if you have problems then restore.

To be on the safe side, backup your iPhone, do a full restore from iTunes, then restore the backup

That's true, but I would update first and do this if you have problems.

Here's why I don't think you need to restore. When you install something with Cydia, it goes into the system partition. When you update or restore, that partition gets completely wiped and replaced. The most tweaks save data and preferences to their own separate location. The only time you'd have issues is if you installed one of the few tweaks that alter app or user data without staying correctly sandboxed like most tweaks.

What's the advantage of update over full restore?

Update is much faster and you don't run into extra problems with things not syncing or restoring.

Edit: of course disadvantages are that it can create more, unidentifiable errors

Thanks guys. Is there any way to just update over the air, right on the phone? I don't have iTunes installed and try to avoid having it on my PC's.

Go to Settings > General > Software Update

I don't think so....OTA update on a jailbroaken phone wont work. Jailbreak prevents it.

Right. There's a good reason for that.

 

[bbrks]

Well, obviously

Nope. OTA updates are disabled when jail broken.

 

[eyoungren]

Well, obviously

I was adding my agreement to your statement and implying a reason as to why that is, LOL.

 

[bbrks]

makes perfect sense

No.
You need to restore with iTunes.

the prefs of cydia tweaks seem to remain even after restoring from a backup. when i jailbreaked again after a while on a different version it still had all the settings of tweaks i had on my last jailbreak so clearly it didnt wipe everything

Yeah it doesn't wipe everything, just the stuff that causes issues. Preferences are just plist files. They won't cause any harm or run code on their own.

Why do you want to un JB? I missed the signing window on my last attempt

I'm old. I do dfu then restore as new w out using backups for 100% purity. Overkill, but who says rebuilding virginity is easy lol.

JB is useless for me, there is nothing that works on a 6s plus. I haven't jailbroken in quite some time so was surprised at how many JB apps are not around anymore in general. But even the JB apps which are still around don't work with the 6s series.

Really? It's got to be some other issue.

I have about 20+ or so of my normal 60+ tweaks working. I have a 128GB iPhone 6S+. There are a few I am waiting on updates for, some that require some finesse, a few I no longer need and a few that aren't working as expected. But in general the ones I have installed are working.

Like??? The ones you don't see anymore is because Apple has implemented a similar thing into the os
