2. Download a firmware package explicitly labeled for Huawei LUAL02 / MT6735M. Prefer vendor/official or well-known community sources.
3. Verify package integrity: compare MD5/SHA1 if provided. Open archive and confirm presence of:
   • scatter.txt (MT6735M scatter)
   • preloader (or preloader_xxx.bin)
   • lk or boot.img
   • recovery.img
   • system.img
   • persist/efs files (if included)
