简介
这是专业级维修，需要特殊的工具和技能。
更换 iPhone 11、11 Pro 或 11 Pro Max 上的显示屏并非易事。 Apple 的软件和硬件紧密集成，这意味着只有授权技术人员使用 Apple 工具和部件安装的显示器才能完全正常运行。 您可能在第三方维修店或在售后市场更换屏幕后遇到过可怕的“重要显示消息”。
当 Apple 的诊断软件检测到非正品显示屏时，此错误本质上会禁用自动亮度和 True Tone 等某些功能。 绕过这一限制需要先进的技术技能，打开手机，并对微控制器芯片重新编程。
本指南将逐步介绍安装新显示器并同时保留完整功能的过程。 我们将介绍：
- 访问 EEPROM 芯片所需的工具，如 SPI 闪存器和烙铁
- 安全拆卸手机而不损坏
- 读取并备份原始EEPROM数据
- 刷新微控制器以重新启用 True Tone
- 重新排列旧屏幕的显示组件
- 保护和测试新显示器的连接
这是一个复杂的过程，但遵循本维修手册，即使是未经认证的技术人员也可以更换 iPhone 11 系列屏幕，同时保留原始校准和功能。 准备好开始了吗？ 让我们首先收集必要的工具和零件。

视频概述

为什么 iPhone 11 系列手机的会显示维修警告？系统会在启动后，验证触控模块的数据。由于触控模块在屏幕背面，更换屏幕会让触控模块的数据发生改变，从而与手机上的原有数据不匹配。
-
目前为止，唯一的解决方案是将原屏幕上的触控模块重新焊接到新的屏幕上来。
-
此外，由于触控模块位于屏幕背面，传统脱焊工具会很容易损坏屏幕，因此，我们今天将会采用一种新的芯片打磨工具。
-
-
-
-
在被更换的旧屏幕上的触控模块周围贴上耐高温胶布，然后用保护膜包裹屏幕。
-
现在我们将要使用电动芯片打磨工具把触控模块从屏幕上取下来。
-
当焊点露出来的时候停止打磨。用 PCB Cleaner 浸湿的棉花清洁焊盘。
ciao ho provato a fare questa molatura ma il mio display acquistato e diverso ce un coperchio e sotto un chip con delle resistenze a fianco forse devo acquistare un display specifico ? mi fai capire per favore questa cosa grazie

现在我们需要取下原装屏幕上的触控组件，然后将它装到新的屏幕上。
-
断开原装屏幕上的听筒、扬声器排线和传感器排线，然后在触摸排线下放一张纸。用热风枪加热，然后取下触控模块。
-
在触控模块上镀低温焊锡。用电烙铁以 365℃ 加热，去除残留的锡和胶。用吸锡带彻底清洁焊盘，然后用 PCB 清洗剂清洗。
-
用相同的方法清洗触控模块，并为其重新上锡。
This is a very incomplete guide. There are no instructions on how to properly reball the IC after you have removed it.

-
现在我们需要把植锡后的触摸模块焊接到新的屏幕上。
-
在焊接之前，将一个金属撬片放在触摸排线下。也可以在这里涂一些酒精，这里的金属薄片和纸是用来隔热的，这样焊接时的高温就不会损坏屏幕。
-
在焊盘上涂抹助焊剂，将芯片防放在正确的位置，使用热风枪进行焊接，直到它归位。
You have mentioned using the protective film in the Step 3. For al viewers in this page, Protective Film is called "Kapton Tape" which is High Temperature Tape Protection from heat absorption. This is safer to use than inserting a paper in between flex cable and metal back frame. Paper will easily get burned (the author knew it). And , you might burned your LCD using the technique written in here. Unless, you are a proffesional Technician you can do the risk that the author is telling.

If we change it by an original display, we must change the touch ic?
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.
Wow, this is a great write-up. Thanks so much for the help! That said, I don’t do customer repairs, but I refurbish and resell. Things like this are why I have left the iPhone scene. Not worth it for me because I can choose to not get involved.
We used a programmer (JCID V1S) to rewrite the data on the new replacement screen (original used) and the problem still persists. We really dont want to solder a new IC on the screen, is there anything else we can try with a programmer? Will an update to V3 help? Cheers
I have the same issue, despite using JCID Wifi. I programmed the new one with the data of the old display. Have still this warning message though. Did you solve that issue?

hello congratulations for the video I tried to make this project on my iphone but I have a problem IC of the display purchased after scratching it there are no pins of the original ic but a chip with resistors maybe not all the displays purchased have the same ic? sorry my english
Si infatti nella guida c’è ben descritto che il problema è legato al modulo e non dall’origine del display. La domanda è : vorrei acquistare un programmatore della jcid , sono un appassionato fai da te con un po’ di esperienza, copiando i dati del vecchio display originale e copiandoli sul nuovo OEM , funziona 100% e nn si verifica più l’errore? In attesa di un vostro riscontro distinti saluti
quello che mi stavo chiedendo anche io, seguo la discussione.

I swapped the oem ic but was to to copy truetone function on my iphone 12 pro max after that i changed the display ic also i thought that the truetone data is stored in the display ic but after changing the display ic i got the imporatant display message back ! I dont understand how is this possible i have tried everything to remove the message again i also reballed the oem touch ic again but no sucss can anyone please help me how is this possible ?
I've seen there's a way to restore True Tone for iPhone 11 using iCopy Plus device, which also has interface for iPhone 12 / pro / max, but I haven't tried myself.
