Prerequisites

Before starting the flash, ensure that:

• The phone battery is charged to at least 60–70 %.​

• A Windows PC (64‑bit) is available with Nothing Flash Tool installed.

• All Nothing/MTK/Qualcomm drivers are properly installed.​

• You have downloaded the correct firmware such as CMF_Phone_1_OS_3.0_20250111.zip from a trusted site like gsmxr.in

• Take a full backup, since flashing wipes all user data.
