How to upgrade iPhone 6 to iOS 13

The same goes for iPhone 6 owners. Although you can find photos of the dark design of iOS 13 iPhone 6 on the web, it was actually a joke.

We are talking about a post in the popular hacker NighttigerFTW, who claimed that he was able to bypass Apple’s blocking. However, he could not tell how he managed to install iOS 13 on the iPhone 6, and after a series of critical comments from colleagues, he said that it was a joke.

The same photo of iOS 13 on iPhone 6, posted in

Note! Many users believe that Apple has also discontinued support for 6S and 6S Plus, but this is not the case.

How to access iOS 13 Beta profile

The principle of activating the iOS 13 beta profile is similar to a simple firmware update using a PC on MAC X OS, which was mentioned above. But there is a small amendment. this also requires an Apple computer, but additionally with a beta version of the operating system. According to the official instructions, you need either beta macOS 10.15 Catalina, or or Xcode 11. But if neither one nor the other, you can use special driver programs. For this, the familiar MobileDevice or any other analogue is suitable for many. The utility still needs a PC with an Apple operating system.

  • the aforementioned PC with the corresponding OS or program;
  • installed the latest iTunes or Finder (if there is a version of Catalina);
  • USB cable;
  • downloaded iOS 13 beta (easy to find on the Internet);
  • iPhone starting from the seventh generation or SE (which is not a shame).

Note! If any beta version of iOS is already installed on your smartphone, you need to uninstall it by going to the settings, section “General” and in the item “Profile”.

  • Install a pre-downloaded utility (if the required OS version is not available).
  • Launch iTunes or Finder.
  • Connect iPhone via USB.
  • Wait for synchronization.
  • In iTunes or Finder (the utility must be the most recent), click on the device icon and go to the “Overview” section in the left menu.
  • Then click in the new field on “Update”, while you need to hold down the “Options” button, it is “Shift”, and in the pop-up window select the pre-downloaded beta firmware.
  • Wait for iPhone to finish updating.
  • Quit iTunes and turn off your phone.

If everything is done correctly, developer rights will be activated, and the user gets something like Root rights in Android.

How to install iOS 13 on iPhone 5s

In fact, back in 2019, Apple announced that with the release of the 11th generation of the legendary smartphone and the new version of iOS, it would stop supporting the frankly outdated iPhones 6 and older. Therefore, the owners of the 5S model did not receive a notification about the release of a fresh update.

The new version of Apple’s software is popular due to the presence of night mode

Unfortunately, the efforts of third-party developers and fighters against the capitalists from Cupertino also came to nothing. There are no keys to installing iOS 13 on unsupported iPhones today.

Note! In fact, it makes no sense to install the thirteenth version of the firmware on 5 S, since due to the high requirements, the characteristics of the phone will not pull the normal operation of the software.

What is iOS 13 Developer Profile

After the presentation in September, Apple offered licensed IT professionals to download the iOS 13 developer profile. In principle, this is a standard procedure, but with the release of the new firmware it became more difficult to do this.

For starters, it’s worth mentioning that the developer profile is such a feature for those who are involved in creating applications on the iOS platform. Simply put, by activating it, programmers and IT studios can test their product before the official release.

And if earlier anyone could install iOS 13 beta, now, as Apple representatives say, “beta firmware was created for developers and nothing more.” Nevertheless, with the help of some loopholes, it is still possible to activate the mode without a license.

The firmware information will indicate that this is a beta version

Important! If you put it in beta, many mobile apps like social media or online banking might not work. In principle, this mode should be used on the gadget that you do not mind.

Can’t update iPhone. what to do and what to do?

Hello everyone! Most recently, I faced such a problem. my iPhone categorically refused to update to the new firmware version, both through iTunes and through iCloud. I just displayed the inscription. “Failed to install the software update. An error occurred while loading iOS. ” Although, in fact, the update was not only available, but already downloaded to the device. A riddle? Even some! But the “answer” was successfully found by me and now my iPhone is running the latest mobile axis.

And, of course, I could not help but share this joy and wrote detailed instructions on how to successfully solve the problems associated with installing new firmware versions on Apple devices. Wow, how bent! 🙂 Let’s go!

The first thing you should pay attention to is whether your device supports the version of the software that you are trying to install. For example, iOS 14 (as well as its modifications) can be “installed” on:

  • iPad mini 4th generation, iPad Air 2nd generation, iPad 5th generation, iPad Pro and older.
  • iPhone 6S and all subsequent devices in Apple’s smartphone lineup.
  • iPod touch 7th generation.

Have you checked? Does your technique fit this list? If the answer is yes, then we proceed as follows.

In the main menu, go to settings. basic. profile (at the very end of the list).

By the way, it was this method that helped me, for some reason it interfered with the update. “iOS beta Software Profile”. Apparently because I often install test firmware and get access to new functions before anyone else 🙂 Do you want it too? Read. How to Install iOS Betas.

After removing it, everything went “like clockwork” and took a fairly small amount of time (about 20 minutes).

In any case, here are a few more points that may prevent the installation of new software and it makes sense to pay close attention to them:

  • Check the charge level, it should be more than 50% or simply connected to the mains charger (Important! It is recommended to use the charger from the outlet!).
  • It may well happen that Apple’s servers are overloaded. this often happens on the days of presentations and the release of new versions of iOS. How to check their status at the moment. read here. In this case, it remains only to wait, usually not much (from 1 hour to a day).
  • A trivial thing. check if the Internet is functioning normally, if the connection is poor, the update process can take a long time.
  • If the update cannot be performed directly from the device, then you can and should use iTunes for this operation. Make sure that the version of the program is the latest (how to do it?). Almost always, when you connect your iPhone or iPad to your computer, iTunes itself will offer to install a new version of the software. If this does not happen, then we will install the update forcibly. To do this, we use this instruction for restoring the software (Attention! Create a backup copy so as not to lose all data).
  • Changing the USB port, Lighting cable, Wi-Fi hotspot, computer in the end can also help troubleshoot problems.

As you can see, there is nothing complicated. all the tips are quite simple and easy to do at home. But, at the same time, their implementation will almost 100% help to put the fresh version of the software on your iPhone. So we need to act!

Addition! Updating over Wi-Fi may be interfering with an inoperative fingerprint reader. Is the fingerprint sensor not functioning on your device for some reason? Installing a new firmware version is possible only through iTunes. And one more thing. if you are faced with the error “Unable to check for iOS update”, then this instruction will suit you. Wow, I don’t seem to have forgotten anything 🙂

After all the manipulations, the iPhone still does not want to be updated or does it get incomprehensible errors? Write in the comments. we will figure it out together!
