There are pros and cons to upgrading, depending on which one you prefer.

The so-called computer upgrade is just a software flashing of the vehicle ECU.

First of all, we must know that the car OTA refers to the upgrade of the system, and its advantage is that it can be improved, fix vulnerabilities, or get more functions and performance improvements, or improve the visual effect. This is also the reason why some 4S stores want to upgrade for free.

Introduction to Car Upgrades

OTA refers to the automatic update package and upgrade according to the Internet. The current vehicle OTA can be divided into two types, one is to be able to change the vehicle's automatic control system in many ways, the rechargeable battery intelligent management system, and the main performance of its repair and upgrade vehicle characteristics, and even according to the preset hardware configuration, according to the middle and late OTA slowly open to the outside of some new roles.

There is also another one that is applied to traditional gasoline vehicles, because the attributes of its Kailu system are different, and the characteristics of the car cannot be improved according to the OTA, and it is only applicable to the upgrade of the car on the multi-**, which is relatively concise, such as the goodwill head GKUI system software.

4S is recommended to upgrade to the system version of ios8.

iOS 8 brings a new flat vision and support for third-party input methods.

The upgrade operation is:

Step 2: Connect your iPhone4s to your computer with a data cable.

Step 3: On the summary page, click "Check for Updates" and follow the iTunes instructions to upgrade the system version.

Upgrading to the latest version feels pretty good, and now it's convenient to jailbreak if you want to jailbreak like perfect jailbreak.

There must be.,Can't turn it on.,Upgrade.,You can still jailbreak.,It's okay.,Upgrade to the latest compatibility.。

I upgraded it two days ago, and the new feature is that the camera can be directly launched by pushing up on the locked interface. There is also an improved battery life. Personally, I don't think it's much use, it's still the same thing when I play more.

It didn't help much. Then there is Siri's support for Japanese. I'm patriotic so I ignore it.

When upgrading, you only need to use a thumb to do it, iTunes will complete the upgrade for you, and it will not have any impact on the ** things that are separated, and the software is there. So it's recommended to prepare for a jailbreak, don't upgrade.,Even if you're not ready to jailbreak, don't rush to upgrade.,Now it seems that you can't downgrade.,I drank too much that day.,I'm very sorry.。。。

No, the new system is not stable.

First of all, now is an excellent time for iPhone 4S to try the iOS 9 beta. After a period of testing, iOS 9 is very stable, just like the previous system, and although it has some minor problems, it is not very serious.

The iPhone 4S won't get all the features of iOS 9, but there are still a lot of things that are compatible with Apple's latest system. Although many netizens reported that the phone was still stuck after updating to ios 9 beta, we should not forget that now we are only installing the beta version, and after the official version of ios 9 is released, perhaps these problems will be improved.

Second, if your iPhone 4S is a 16 GB version, then you can safely upgrade your phone to iOS 9. You must know that last year, Apple's 16 GB version of the device updated the iOS 8 system was extremely difficult, because the new system took up more than 4 GB of space on your phone, but this year you only need to use the remaining space to complete the installation of iOS 9. iOS 9 can bring a lot of new features to our phones, so if you really want to give iOS 9 a try, your iPhone 4S shouldn't be struggling.

Thirdly, compared to the upcoming iPhone 6S 6S Plus, the iPhone 4S updated with iOS 9 will obviously not be equipped with all the new features, after all, it is limited by its own hardware and performance, as for what iOS 9 can bring to the iPhone 4S, next month, we will naturally see, I think many iPhone 4S users will be happy to try it.

Finally, iOS 9 is likely to be the last major update for the iPhone 4s, and this classic phone will last until the release of iOS 10 next year, and it has already done a lot of wonders. The iPhone 4S should definitely miss out on iOS 10, so we upgraded the iPhone 4S to iOS 9, which is also a tribute to Apple's classic, after all, it represents an era, and it is said that the iPhone 4S will get every version of iOS 9 updates, such as the rumored iOS.

Many friends have replaced the new iPhone, but the iPhone 4S still has a special meaning for them, even if your iPhone 4S has not been used for a long, long time, if you are not too troublesome, if you really love it, then you might as well wipe off the dust on it, let it burn the last light, run the latest system for a run!
