Single RAR archive of 864 MB with an auto-patch scatter package for model A013F, binary revision U5, Android 10 (OS10). The name says it performs a reset without losing network, which suggests the modem and NV data are preserved during the flash. Scatter files are the MediaTek partition map read by SP Flash Tool and service boxes. Since patched packages modify stock partitions, test on a known unit first, make sure the device bootloader is U5, and back up NVRAM in case IMEI or signal is affected.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @mrepairo. Enginerys does not host this file.
