After the iphone is upgraded to 2 2 15H11, can it still be used?

Are you a machine from the Hong Kong version? I don't know what you mean when you say it can't be used, why can't it be used, is there no signal? If you're not the Hong Kong version of the unlocking machine,It's the American version, the European version, the Australian version of the locked machine,Then the person who repaired it is right.,You can only wait for the next version to crack.,Devteam will definitely not crack it.,As for when Apple will release the next version.,As for when Devteam can crack it after it is released, it's unknown.,1 year、Even 2 years later, it's possible.,Before that, you can inquire about the card that you don't have.,But the signal with the card will be very, very, very poor., Be mentally prepared.

In addition, I heard that some maintenance can be downgraded, you can inquire, but you have to keep an eye on the maintenance to disassemble the machine, there are too many js, don't let him replace your parts. There's really no way to use it as mp4.,It's good.,Didn't the buddies who mistakenly upgraded their phones and bricked them survive? Blame yourself for ignorance and take it for granted.

Take a look at forums like Weifeng.,You'll have a lot of gains.,I'm the same as you at first.,I don't understand anything (but the hand is not as fast as you = =!.), all of them are learning while watching, I wish you to save your little i :) as soon as possible

In reply to your adding: Of course there is.

It's that the signal will be bad, especially when changing the base station or switching on and off, the signal will not be found or the line will be disconnected, but it can be regarded as a solution, and it will be used.

It depends on whether there is a lock or an unlocked version, and the card that can be bought if there is a lock. Of course, the unlocked version can be used.

Once upgraded, you won't need a sticker!

Re-flash the machine!

On the ** network, now a lot of pulling. You can go on.

Look for a lot of them, or in some blogs, I sell iPhones, there must be.

It is clear that the iPhone 6 can be upgraded to iOS 11, and it will not become a brick move, but there is a certain premise for this. Only rumors on the Internet show that machines involving damaged fingerprints, overhauled phones, and phones that have upgraded their internal storage may not activate after upgrading to iOS 11.

In this case, simply put, because the internal components have been replaced, they are not the original products, and the system cannot be activated when the machine is turned on for the first time after flashing, so the system cannot be activated. In addition, if the OTA is upgraded to iOS 11, this problem will not occur in theory, and the user can activate it normally. If you use DFU mode to fully upgrade, you will not be able to activate it.

And it should be noted that this situation is not only on the iPhone 6, but also on the iPhone 6 6 Plus 6S 6S Plus, which has been repaired and replaced by a third party.

Finally, when it comes to the question of whether iPhone 6 should be upgraded to iOS 11, the simplest answer is not to upgrade. Someone has done a survey, participating in the survey has upgraded iOS 11 iPhone 5s, iPad mini 2, iPhone 6, iPhone 6 plus, iPhone 6s and iPhone 7, etc., in addition to iPhone 6s and iPhone 7 users, the rest of the users who participated in the survey said that after upgrading iOS 11, the system has an obvious sense of lag, and even software crashes, etc., and iPhone 6s and iPhone 7 This is rarely the case.

It is said that after the upgrade, it is already very hot to check the route with the map, not to mention the heat of playing games with a mobile phone. At this point, iOS 11 is not enough for old phones, and it may be difficult for old hardware to run new systems. If you care more about the user experience, the iPhone 6 should never upgrade to the iOS 11 system, and it is very good to use under iOS 10, and the process is smooth.
