iPhone 8 Stuck In Apple Icon When We Try To Power On

Being different from the former editions, iPhone 8 has a built-in hardware detection for booting process. The moment Touch ID gets malfunctioned, the iPhone 8 gets stuck in Apple logo during start-up and can’t move on pass it to the home screen. What’s more, the other iPhone features become inaccessible.





Traditional solutions for iPhone stuck in Apple logo issue can be diverse. Since iPhone 8 is the latest product of Apple, the situation can be much more complicated. In this article, I will tell you a completely new solution about how to solve the iPhone 8 stuck in Apple logo problem.

Troubleshooting :

--Power on the problematic iPhone 8, Apple icon displays correctly. But a few seconds later, we can see that the Apple icon still remain in screen.

--Connect the phone to computer and restore though iTunes. Then insert a SIM card and activate the iPhone.

--The Home Button turns unresponsive with returning function and the phone fails to be activated completely.

--Disassemble the phone by screwdriver and disconnect the battery. Then remove the display assembly.

--Measure the power supply voltage of Home Button. The measurement voltage value is 3.3V, 1.8V and 2.75V. The three measured voltage value are normal. Check whether the 3D flex cable of the display assembly is damaged or not. The 3D flex cable is in a normal situation.

--Detach the Home Button and check whether the home button flex cable is damaged. The home button flex cable is in normal status.

--It is connected to logic board with flex cable on the display assembly, to further confirm the fault point, replace with a new display assembly.



--Get the Home Button mounted on the new display assembly. Buckle the new display assembly to the logic board. Then power on.

--The phone still gets stuck in Apple logo and can’t boot up completely.

--Remove the display assembly. Switch to diode mode and measure the resistance between J5800 pins and grounding. We get a normal resistance value. There are obviously repairing marks on J5800 under the Fix 7-45X Trinocular Stereo Zoom Microscope . So we can have the connector J5800 replaced for a try.

--Take out the logic board and attach it to PCB Phone Holder. Stick connectors next to J5800 with high temperature adhesive tape.

--Apply some BGA paste flux to the bonding pad and take down J5800 with Hot Air Gun at 320℃.

--Then Solder tins with Soldering Iron. Which is helpful to the subsequent soldering process. Clean with PCB Cleaner afterwards.

--Apply some BGA paste flux to the bonding pad. Align the new connector to the right place. Then solder the new connector with Hot Air Gun at 320℃.



--Wait for the logic board to cool for 3 minutes and then clean with PCB Cleaner. Check again to confirm soldering status.

--Get the logic board assembled and connect to the battery. Buckle the display assembly and power on. The phone gets access to the activating interface normally.

--Insert the SIM card and activate the phone. The Home Button gets responsive with returning function. Yet Touch ID failed.

--So we need to restore again via iTunes. Once finished, activate the phone again. Touch ID back to normal this time.

--With a carrier lock built into the phone, take out the SIM card after the activating process. Only in this way can we move to subsequent function test.

--Do a the function test. We find all are going well. Malfunction are cleared.

2 What is Jailbreaking?

 

Jailbreaking is about freeing your IOS device, you can install any app you want. But if your device is a non-jailbroken, maybe you will be restricted by the IOS system. Anotherboard ,jailbreaking is a process which apple company allows, but it just don't claimed by official, you just ned to run a unsigned code, it is easier process, but if you are not a professional repair man, maybe you have no chance to get this code. 

 

3 What you can get through jailbreaking?

 

The directly benefit is to have the rights to install third-party applications. More and more app comes here, but not all of them can be used in IOS, if your phone hase jailbreaked, you don't need to worry about it.

 

Sametime, jailbreaking also can give you access to tweak, mods and extensions, it can bring subtle improvements to the way your IOS device operates. According to our ever repair experience, a lot of peoeple will choose jailbreak their IOS to unlock it for a different working way. If you want to unlock your iPhone, no matter whether you are a professional repair man, you need to jailbreak.

 

4 Is Jailbreaking Legal?

 

So, i want to ask you a question, if you know it is illegal, will you choose non-jailbroken? I guess the answer will be the same. As we know, jailbreaking is legal in US the hometown of iphone CEO, though there eixst a period of time the jailbreaking was considered illegal by US goverment as of copyright litigation. 

 

And people all over the world have chosen jailbreaking since 2007, no matter which country you are in. 

 

5 Does Jailbreaking Void my Warranty?

 

The answer is certainly, yes. If your phone happens some fault in warranty, you can send it to the factory, you will enjoy the free repair. But if you have a jailbroken in your iPhone, you will be told you can't receive the customer suppoer because you voided your warranty.

 

And we will share a dialogue about jailbreaking in customer supporting:
“Apple strongly cautions against installing any software that hacks the iOS. It is also important to note that unauthorized modification of the iOS is a violation of the iPhone end-user license agreement and because of this, Apple may deny service for an iPhone, iPad, or iPod touch that has installed any unauthorized software.”

If you really have to take your iOS device to an Apple store, you can always restore it to its factory settings in iTunes. This will bring your iOS device back to the way it was when you first bought it, and Apple will have no way of telling that you ever jailbroke.

 

So if you can ensure you can protect your phone well in its warranty, you can try to jailbreak it. But if you can't do it, we advise you had btter not do like this, or you will have to afford the extra pay in a phone accident

 

6 Whether it will be a brick if i jailbreak

 

I want to tell that it will be impossible now, a few years ago, maybe it could happen, but for now IOS system has updatede though it still can't allow the jailbreak official, but it can make sure your phone runs stability.

 

And if you jailbreak it, the worst thing is your phone become unresponsive, for now you need to keep calm, if you can ensure it just was caused by the jailbreak failure, you just need to back to its original state. Or you need to check it carefully, find the soures fault with professionl phone repair tool.

 

7 Is Jailbreaking the Same as Unlocking?

 

No, jailbreaking and unlocking are two different things totally, you must jailbreak first if you want to unlock your phone, so that is the relation between them. jailbreaking let you install third party application  while unlocking allows you to use your iPhone on a different carrier.

 

8 Will happen some change after jailbreaking?

 

It won't cause any change in your device, you can continue useing the iTunes and the App Store, The only change is there will be a new application on your device called Cydia. Sametime, it won't prevent you from updating IOS, no any other changes will happen.

 

9 What is Cydia?

 

In short, Cydia is like the App Store of jailbreak applications. Just like the App Store, you can browse Cydia for apps, tweaks, and mods. Just like the App Store, you can download and install Cydia apps effortlessly. Most apps and tweaks in Cydia are free, but it is not unusual for a jailbreak app to sell for a few dollars.

 

10 Three types of jailbreak

 

There exist three types of jailbreaks in market: tethered, semi tethered and untethered, if you are interested in it, you can search some related info in google searching

 

11 Is jailbreaking easy?

 

Like we have talked about, you just need to download a software which can burn the code into your computer, then transfer it to your phone, the jailbreak can be done, no other specific knowledge or skill required. But do remember, find the right and safety code, or you will be attacked by hacker.

 

12 Does it cost anything to jailbreak?

 

No. You should never pay for a jailbreak. But maybe you need a jailbreak tool for this operation.

 

Maybe you will have a new know about jailbreak through this article, jailbreak will provide an another playing joy, but you also need to remember that you will have to afforded the cost if the phone happens some fault thouth it still is in warranty.
