    • Why the Display Repair Warning for iPhone 11 series appears? The system will verify the touch module data during start up. Since the touch module is located on the back of the screen, screen replacement can result in a mismatch between the touch module data and the phone.

    • The only workable solution by now is to solder the touch module of the original screen onto the new replacement screen.

    • Also, since the touch module is located on the back of the screen, traditional desoldering tools can easily damage the screen. We will adopt a new chip grinding tool today.

    • Stick high-temperature tape around the touch module on the replacement screen. Then wrap the screen with protective film.

    • Now we will grind the touch module with the electric chip grinding tool.

    • Be patient during the grinding. Start with the top layer then move on to the next layer. Also, be careful not to damage flex cables nearby.

    • With solder joints coming out, stop the grinding work. Clean the bonding pad with PCB Cleaner soaked cotton swap afterwards.

    • Then apply low-temp solder paste to the touch module. Heat with Soldering Iron at 365℃ to clean residual solder paste and black adhesive. Clean thoroughly with Solder Wick afterwards. Then clean with PCB Cleaner.

If we change it by an original display, we must change the touch ic?

Augusto Luz - 답글

Or you must buy a board that copy the data from the old screen to the new.

Do you know where to buy the board which can copy data from original screen onto new screen?

Cazzate, il problema si presenta anche se cambi con un display originale (provato personalmente a spostere un display originale tra due iphone 11)

Hai letto per bene la guida? C’è scritto che il messaggio non dipende dall’originalità dello schermo, ma dal modulo touch, che deve essere trasferito dal vecchio pannello del telefono a quello nuovo. Oppure è possibile acquistare delle schede che copiano i dati dal modulo e li sovrascrivono sul nuovo.
