Product Description
The Samsung Galaxy S25 Ultra relies on internal ribbon cables to connect the motherboard to its other components. This main motherboard connector ribbon flex cable is a replacement made for the S25 Ultra, for when the existing ribbon has been torn or damaged.
It is reached by opening the phone, so expect to use heat and careful prying, and handle the ribbon gently once it is exposed. Compare the new cable with the old one before fitting, so the routing and connector ends look alike on your Galaxy S25 Ultra.

Compatibility
- Samsung Galaxy S25 Ultra
Signs Your Flex Cable Needs Replacing
- A function linked to the flex (such as display signal, charging, buttons, signal or sensors) stops working or cuts in and out.
- The fault appears after a drop, liquid exposure or a previous repair.
- The flex is visibly torn, creased or has a damaged connector.
- The problem changes when the phone is pressed or flexed.
- Before replacing, reseat the connectors — a loose connector can cause the same symptoms.
How to Check Your Model Number
On the phone or tablet go to Settings › About phone (or About tablet). The model number starts with SM- (for example SM-A145R). It is also printed on the box the phone came in.

Frequently Asked Questions
What does the Galaxy S25 Ultra main motherboard flex cable connect?
It links the motherboard of the Samsung Galaxy S25 Ultra to other critical internal parts, so a damaged ribbon can interrupt those connections.
Is this motherboard flex only for the S25 Ultra?
Yes. It is listed for the Samsung Galaxy S25 Ultra. The S25 and S25 Plus are different models, so confirm your exact phone before ordering.
Does the Galaxy S25 Ultra have to be opened to change this flex?
Yes. The S25 Ultra needs to be opened with heat and prying, and disconnecting the battery first is sensible before you touch the ribbon.
Are tools included with the S25 Ultra motherboard connector cable?
No. Only the ribbon flex cable is listed for the S25 Ultra, so you will need your own tools.
Should I get a technician to fit the S25 Ultra motherboard flex?
Professional installation is recommended for the Galaxy S25 Ultra to avoid damaging the ribbon or nearby parts.
