iPhone X Logic Board Repair
The iPhone X logic board is a whole new animal. All of the iPhone logic boards prior to the iPhone X were one piece:The iPhone X logic board on the other hand is made up of two pieces held together by a middle connector ring, which is soldered to both separate logic boards.
It’s obvious that Apple’s design was to save space within the iPhone housing, so that they could make the battery capacity bigger, since the battery takes up more than half of the real estate in the housing.
The one thing that has been causing most of the logic board problems on the different iPhones is the fact that housing bends most of the time. The logic board is held into place with screws tightened to the housing, so any bending of the housing also causes bending to the logic board.
The picture above is an image of the two logic boards and the middle connector ring. Notice that the three pieces are separated from each other near the middle. This means that the solder joints have disconnected from each other.
As you can see in the picture below, when the two logic boards have disconnected from the middle ring, you’ll often see missing pads. In this case, there are many missing pads.
All of the black/brown spots are supposed to be silver and shiny like the other ones on each side. There are hundreds of these pads, which connect the two logic boards.In order to fix the logic board, one would need to desolder the two logic boards along with the middle ring, fix the missing pads by running jumpers for each necessary pad, THEN put everything back together and hope it works. As you can imagine, repairing the iPhone X may not be the most feasible thing to do. Especially when a lot of these pads run under other chips:
Unfortunately, there is no easy way to run a jumper under a chip to a missing pad. One option would be to transfer the wifi chip (UWLAN_W) and the baseband chip (cell service) to another donor logic board, but doing that itself is no easy task. And the last thing is, how could anyone warranty this type of repair? If a repaired iPhone X comes back in as a warranty repair, it would most likely take a few hours to try to fix again. With all things considered, I don’t see an easy way to repair the iPhone X. However, data recovery is a different story.
iPhone X Data Recovery
The bad thing about the iPhone X is that repairing the logic board is going to be very difficult. The good thing is that the success rate for data recovery should be pretty good. The reason being, the iPhone will still boot with another bottom logic board from another iPhone X. So, the typical data recovery will go as follows:
- Disassemble the logic board.
- Separate the top logic board from the middle ring and bottom logic board.
- Place a known good bottom logic board/middle ring into an iPhone X jig (e.g. iSocket, JC TX-BAS) and then attach the top logic board.
- Boot up the phone with a known good screen, charge port, and battery.
- Do a backup into iTunes.
This is what an iPhone X jig looks like:
Using a different bottom logic board prevents the wifi and cell service to work since the original cell service and wifi chips have to be used in order for them to work, which is why you see the triangle icon at the top right and no wifi networks to connect to.
Unlike previous versions of the iPhone, the path to data recovery on the iPhone X is actually easier than repairing the logic board. In terms of repair, at this point, I don’t see a feasible solution to repairing the iPhone X due to the amount of time that it would take to diagnose and repair. And I don’t think anyone would logically want to warranty any type of repair on the iPhone X.
If you would like to your data recovered on the iPhone X, then please contact us using the request a quote form. If you want your iPhone X repaired, then you can still contact us, but understand that data is the only thing that we would be able to guarantee.

One problem that we’ve been seeing with the Nintendo Switch is a broken charging port. What happens is that with frequent use, the charge port becomes loose pulling away from the logic board inside. When this happens, the Switch eventually loses power when the battery runs out or you need to wiggle the charging cable in order for the Nintendo to charge properly.
The Nintendo Switch uses a usb-c charging connector that looks like this:
If you look at the port, then you’ll notice that there are actually two rows of pins on the bottom that attach to the logic board, which makes it a very difficult repair because there is no way to access the inside pins with a soldering iron. The only way to solder a new charging port on is to use heat. The problem with heat is that there is plastic on the connector as well and plastic melts. So, to put a new charging port on, we need to use heat, but not too much of it. You can see a video of our repair here:

We’ve been seeing a lot of these lately. Usually what happens is that the screen on these Samsungs will go black one day, either for no reason at all or after a drop or perhaps after having a cracked screen for a little while. It seems as though the culprit for this problem is a little chip on the logic board called MAX77838. It’s the display IC. This chip handles all of the logic required to power the display and show an image on the screen. Without it, the display goes completely black with no image at all and no backlight. Here’s what the chip looks like:
Unfortunately, the only way to fix this problem is to take this chip off via microsoldering and replace it with a new one. You can watch a video on this repair here:
We’ve also fixed this problem in on a Samsung S7 and Samsung S8. I’m not sure if they use the same chip on the Samsung S9 and S9+ or not, but if you’re having display problems, then it’s most likely this chip that is the problem.
If you don’t have the tools to fix it yourself, then we can definitely help you out. Just fill out the quote request form and we’ll back to you right away.
We’re starting common problem with these iPad Pro 9.7 tablets after a screen repair. It seems as though Apple decided to hold the logic board in place with some pretty sticky adhesive, which makes it very hard to isolate the battery during a screen repair. Ultimately, the technician sticks a guitar pick underneath the battery connector, like they’ve been taught all of these years, but damages the battery connector pins.
Some of the common symptoms are as follows:
- No Charging
- No Power
- Battery Stuck at 1%
Inspecting the battery connector under a microscope, you can see that the 5 pins have a ridge on them, which makes it even more prone to damage.
Depending on which pin or pins are damaged, then you will see one of the problems specified above.
The repair process is as follows.
- Disassemble the logic board. The hardest part in this step is removing the top part of the logic board without damaging the flex below it. The whole thing is held in place with some very strong adhesive and the adhesive sticks to logic board flex and the flex below. It’s awful.
- Remove the black tape from the bottom of the battery connector and desolder the 9 solder joints with the help of some low melt solder. Use your tweezers to push down on the solder joints.
- Resolder the new battery connector. This should be simple through hole soldering. Just make sure that you use ample flux.
