Use this guide to replace a cracked or broken screen on your Xiaomi Redmi Note 8T.
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.
Before disassembling your phone, 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.
You’ll need replacement adhesive to reattach components when reassembling the device.

If possible, turn on your device and test your repair before installing new adhesive and resealing.
Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.
To reassemble your device, follow these instructions in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
The best way to secure the new screen is to apply a sheet of custom-cut double-sided tape to the back of the screen.
Take your e-waste to an R2 or e-Stewards certified recycler.

Hervorande Anleitung !
Bonjour, c'est grâce à ce tuto que je suis fier de vous dire avoir réussi à changer mon écran seul sans payer un réparateur.
Pour enlever l ‘écran je n ai pas réussi à soulever l’écran avec une ventouse en chauffant avec un sèche cheveux ( alors que ça a bien fonctionné pour la vitre arrière).
J ai improvisé alors j ai du élargir une fissure avec un petit tournevis pour soulever l’écran du châssis et ainsi insérer le mediator comme prévu
Merci pour ce tuto…
