How to fix iphone could not be activated because the activation server cannot be reached

Hello goodnight everyone, this time I will share my experience after walking, watching videos and joining idevice forums.

In fact, there are lots of apple devices, especially iPhone and iPad that have problems during the activation process after clean install or OTA upgrade from iOS 10 to iOS 11.

On the internet there are many inconveniences that come from their iPhone and iPad users which cannot be activated, with the following error message:

“Your iphone could not be activated because the activation server cannot be reached.”

Basically, I advise you not to just give up, meaning you have to try everything from easy to difficult even to solve this problem.

The easy things that you should try first are as follows:

• Activation via iTunes, plug your iPhone / iPad into a Mac or Windows computer that already has iTunes updated, try activating from there.
• Log out first at icloud.com/find, log out on your icloud then try activation again.

If you have tried the steps above and did not succeed, then please refer to the statements below that I got from several forums and websites why your iPhone / iPad can not be activated.

• Your iPhone / iPad is refurbish, please googling the meaning of the word iPhone refurbish.
• Your iPhone / iPad replacement (replacement of some parts that are not original).

Upon activation, the iPhone / iPad will match the mac address of WiFi, Bluetooth and SN IC NAND (flash memory) to the Apple server, if the three do not match the Apple database then the activation process cannot be continued.

The most possible way to overcome this problem is to replace / rewrite some of these parts (usually the NAND IC will be rewrite_ so that it can be likened to an Apple server. This method can be done using software and hardware IC programmers. both of these tools.

And for the iPhone 5s it seems that no one wants to take the fix, I don’t know whether it’s not worth it to work on an iPhone under 6 because of the cost factor or indeed the possibility of failure is greater.

Please leave a comment if there is anything that needs to be added related to the activation of iOS 11 in the comments column.
