Before you begin

Can I use these instructions without repair experience?

Software settings are written for regular users. In disassembly materials, separately consider tools, warranty, and the risk of damaging parts.

What should I do before a reset or firmware change?

Save photos, contacts, documents, and account access. For important data, keep a separate copy on a computer or in cloud storage.

Do the materials work for HyperOS and MIUI?

The guide includes instructions for both shells. If a menu item name differs, look for the section with the same function.
