Use this guide to replace a cracked or broken screen on your Xiaomi Redmi Note 7.
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.
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.

This guide is just WRONG and useless.
He disconnect the battery cable and nothing else: if you try this, at step 18 you will just pull a flex cable that is still screwed. The correct ribbon is not the one near the battery connector shown in step 10, but the one on the left under the camera.
Guide shows he removes 3 screews, and these are just to disconnect the battery. After this, it is necessary to remove more screws and actually disconnect the display flex: 1 to free the small metal cover blocking the ribbon (similar to step 9) and 8 more screws on the bottom of the phone to free and remove the loudspeaker, which otherwise will block the display ribbon even if it was disconnected and the first screw I mentioned removed.
Hi A M,
thank you for your feedback. You're completely right. Some prereq guides for the screen guide were set to private and because of that not visible. I made them public and the full display removal procedure should be correct now. If you notice anything else that is wrong or I missed something, please let me know.
