Shared repair archive covering the Xiaomi Mi A3, code name laurel, and the Mi CC9e, code name laurus, packed as a 2.22 MB RAR. The two phones are closely related, which is why one set of documents is offered for both, but the name does not say what files are inside. Extract it to check for schematics or layout drawings, which help trace rails, locate test points and identify components. Confirm which variant you are repairing, since small differences between the Android One and China models may exist.
