A. Flashing stock firmware (MTK scatter-based):

  1. Install proper MTK drivers and connect device in Download/Preloader mode (powered off, USB cable connected while holding volume key per device).
  2. In MRT, choose “MTK” or “Flash” module and click “Load Scatter.”
  3. Select the scatter.txt file from the firmware package.
  4. Choose partitions to write (for full flash, select all except preloader in some cases; preloader only if necessary).
  5. Click “Start” (or “Download”), connect phone if not already, and monitor progress.
  6. Wait for success confirmation and reboot device.

B. Backup and restore NV/IMEI:

  1. Use the “Readback” or “Backup” function to dump NVRAM/persistent partitions.
  2. Save the dump securely.
  3. To restore, use “Write” or “Restore” and point to the NVRAM backup file.
  4. Reboot and verify IMEI via *#06# or Settings > About.

C. Removing screen locks / FRP (general approach):

  1. Boot device into appropriate mode (recovery/fastboot/EDL) as per chipset.
  2. Use the unlock module suited to the chipset (MTK/Spreadtrum).
  3. Follow prompts; some operations will format userdata—warn customers about data loss.
  4. Reboot and verify lock removal.

D. Unbricking via Format + Flash:

  1. If device stuck in boot loop after failed flash, use “Format + Download” (where tool formats certain partitions then flashes).
  2. If formatting preloader is risky; prefer targeted formatting of userdata/cache unless instructed by advanced guides.
  3. After successful write, perform factory reset if required.
