iPhone 7 / 7 Plus No Service Problem

We repaired so many iPhone 7 and iPhone 7 Plus that having No Service problem.

iPhone 7 Plus No Service
If you try to restore it, you will end up like this. Unable to activate the iPhone.
When you stuck in this menu,
Click the "!" exclamation mark at the bottom right.
You can see there is only Serial Number and No IMEI. Then it's confirmed you have a hardware problem.

This problem we called it "baseband" problem

Baseband iPhone 7
The same iPhone above is repaired.
A healthy working iPhone would be like this. MEID, SN, and IMEI.

Why can't activate?
Because Apple needs to verify is the device Serial Number, and IMEI number match with their server or not. Server won't let you activate if the S/N or IMEI missing or not match with their list.

Why No Service?
It is a motherboard issue that one of chipset called Baseband is not working.

Why baseband is not working?
Baseband power circuit shorted due to water damaged.
Solder joint broken caused by heavy drop but the 
problem won't occur immediately, usually happen later.
The red circle is Baseband ic. To repair this, the technician must be very well trained. If not, they'll accidentally kill the A10 CPU which is next on it. Overheated and causing unable to power on.
 Solution and price?
Sorry, we need to open up and check before repair or quote you a price. Because it can be many reasons causing baseband failure.
  • Some just need reball and rebuild the broken tracks/pads.
  • Some are shorted BB PMU (baseband power ic) or components around it. 
  • Some are because some shop attempted to repair another problem but created this problem. We need to fix their mess.
So the price varies. We need to check first.

Last year I wrote an article about this repair.

iPhone 6 Plus Touch IC problem - Why? How?

Now still countless people to ask changing the touch IC...
The most frequent question from the customer that wanted to repair touch ic problem.

Is the price of repair including to replace a "new" Touch IC?

It depends on the condition. If we changed the Touch IC and it's still not working then how? Ask you to pay more?

My answer is it's doesn't matter new or old touch ic. The most important is we solve the problem no matter what it takes.

Someone might be misleading you saying they replace new Touch IC which seems good. 

A real professional won't blindly replace anything. We must find out the source of the problem.  
Not just google and end up a conclusion to change it.
(Please don't expect the Google has every answer. Professional knowledge is hard to get from internet. 
You can't really expect to learn surgical doctor skills by googling.)

A lot of amateurs have the tools and don't have the knowledge or training. They just simply apply the solution that found from the internet and don't even know what's it for.

Sometimes it's not the same source of the problem.

Long-time ago I made a video in 2016 - iP6 Plus Touch IC repair

Now I make a new video at below is to explain why. 


  1. So please stop telling people to change the touch ic. You might mislead the shop to do that.
    What if they can't solve the problem after that and still ask you to pay? 
    Or the same problem reoccurs later?
  2. Be sure to ask the technician to check your LCD first.
    We don't want to have an LCD problem and Touch IC problem together. Or maybe it's just an LCD screen problem.

    They must put the LCD  into another iPhone to test. 
  3. Be sure send to professional to repair the motherboard.

How do I know they are professional?

Professional is able to offer the terms on below
  1. Repair it within 2 hours in the same shop.
  2. Guarantee your iPhone won't be a brick or dead. Anything else happened, they fixed it back no matter what and you won't need to pay extra.
  3. Warranty period is long. (We provide one year warranty)

Advice for beginner technician:

Don't simply apply a solution without a reason. Read the schematic to know why.
If you don't know how to read then join my academy.

iPhone 7 audio ic check test
Three iPhone 7 Audio IC that we repaired at the same hour.
After repaired,
Just go to the Voice Memo test again. It's good if the recording starts.
How to repair this? Why this happening to me? 
I wrote an article and a video here before.

Always send it to a real professional for repairing this issue.

"Having the tools to repair doesn't mean having precise surgical skills and experience."

Send to the wrong shop you will end up having more problems in your iPhone. I saw a lot of customers ended with the problem of "no service". I repaired the mess they created at a higher cost.

Some even shorted the CPU and the iPhone unable to power on.
It is very dangerous by just watching YouTube try to fix it without properly trained.

Send it to our shop for instant repair and collect it on the same day.

We provide ONE year warranty
But not valid if the board been "repaired" by others.
and also not for water damaged.
