Use this guide to replace a cracked or broken screen on your Xiaomi Mi 9T Pro.
If the frame is deformed, it's important to replace it to make sure the new screen will mount correctly and won’t suffer damage from uneven pressure.
If your battery is swollen, take appropriate precautions. Before disassembling your device, discharge the battery below 25%. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged.
Note: This guide instructs you to replace only the screen while leaving the original frame and motherboard in place. However, some replacement screens for this phone come pre-installed in a new frame (a.k.a. chassis), which requires a very different procedure. Make sure you have the correct part before starting this guide.
Before you begin this procedure, be sure to have a set of replacement adhesives for both the rear glass and the screen.

Wer wie ich vor der Herausforderung steht, ein Display inklusive Rahmen zu wechseln, dann wird man schnell feststellen, dass man den Akku ausbauen muss, welcher verklebt ist, was sehr gut funktioniert ist, das gesamte Telefon zu erhitzen, ich nutze dafür meinen 3d Drucker mit Platte auf 50°C.
Lasse das Handy dann einfach drauf und sobald der Akku warm ist (35-40° heißer würde ich definitiv nicht empfehlen - vielleicht noch 45) kann man den Akku ohne zerstörung, ohne großen Aufwand problemlos entfernen, dazu auf der rechten Seite die 3 Klebestreifen lösen und auf der linken Seite ebenfalls, rechts dann am mittleren Element ziehen da bei 1 und 2 der kleber befestigt ist, an 3 nur der Akku, die Kraft ist schwer zu beschreiben, aber wirklich nur ganz leicht ziehen.
Dann kann man den Akku durchaus nochmal benutzen. Wenn der Akku irgendwie beschädigt werden sollte, verbogen etc, auf keinen Fall weiternutzen, nur wenn der wirklich unbeschädigt ist.

Hallo Dominik,
ich habe deine Anleitung befolgt und stehe nun vor einem nahezu perfekten Endergebnis. Nahezu perfekt, weil irgendwie nur meine obere Hälfte des Displays reagiert. Was könnte ich bei der Reparatur falsch gemacht haben? Einen Pin von einem Stecker zerstört? Oder ist das neue Display schon fehlerhaft bei mir angeliefert worden? Hast du da schon Erfahrungen gemacht? Grüße Mats
Could you make a tutorial for replacement of only the front glass?
