Use this guide to replace a broken or defective AMOLED & Digitizer in your Xiaomi Mi 9.
Due to the phone’s design, you must remove the lithium-ion battery to access the display cables. Reusing a deformed or bent battery after it has forcefully been removed, is a potential safety hazard. Replace it with a new battery in this case.
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.

Doppeltes Klebeband. Gibts auch amazon passgenau oder du bastelt dir selbst wad
il manque la partie ou on enlève la batterie (via les petit scotch. de plus la première étape devait être d’enlever le tiroir pour la carte sim
Bonjour Mathieu, merci de votre attention et de votre remarque. La partie du retrait de la batterie a été ajoutée. Par contre, la carte SIM qui se trouve derrière la carte mère ne dérange pas la procédure. Il n’est donc pas nécessaire de commencer par la retirer. J’espère que vous avez à présent toutes les infos pour effectuer la réparation. Bonne continuation !
