Have you ever seen the 'Important Display Message' on iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max devices after third-party display repairs? The notice states, “it’s important for certified technicians who use genuine Apple display parts to repair it.” And those certified technicians include Apple, Authorized Service Providers, and Independent Repair Providers who have been approved by Apple to perform repairs using OEM parts and tools.
How to fix the iPhone 11 Non-Genuine screen issue? Today we'll bring you the only solution that currently works! The first thing we should know is the 'Important Display Message' will appear after third-party display repairs, and has nothing to do with the replacement screen whether it’s an aftermarket screen or an OEM screen. Why the Display Repair Warning for iPhone 11 series appear? As the system will verify the touch module data during start-up, screen replacement can result in a mismatch between the touch module data and the phone since the touch module is located on the back of the screen.
The only workable solution by now is to solder the touch module of the original screen onto the new replacement screen. Here's how we do it.
Step1: Grinding the touch module on the new screen
Since the touch module is located on the back of the screen, traditional desoldering tools can easily damage it. We recommend using a new chip grinding tool for this process. For details on grinding operations, check out our YouTube videos to learn! It's important to note that we should not damage the flex cables nearby during the grinding.
Step2: Solder the former touch module onto the replacement screen
Firstly, we should remove the touch module on the original screen.
Remove the earpiece speaker and sensor flex cable on the original screen.
Heat with Hot Air Gun.
Pry up the touch module on the original screen.
Clean residual solder paste and black adhesive.
Get the touch module reballed.
Second, solder the reballing-finished touch module onto the replacement screen
Insert a metal plate and paper which is used here for heat insulation.
Get the touch module in the right position, then heat with Hot Air Gun.
Next, we just need to assemble the phone and test. Please note that professional motherboard repair techniques and handwork skills are required during the process, screen replacement beginners are not recommended to imitate the operation. Otherwise, you might damage the screen. Start your learning journey with REWA ACADEMY now!
