First part of a scatter firmware dump for model A055F, a 1.91 GB RAR paired with part2. The name does not list a binary revision or Android version, so compatibility should be checked before flashing. Scatter dumps contain raw partition images plus a map file used by SP Flash Tool or a service box to rewrite a device that will not boot. Since dumps come from another unit, back up your NVRAM, IMEI and calibration data first and avoid overwriting them where possible.
