First volume of a three-part RAR set with Android 13 scatter firmware for model A346E, bootloader binary U2, intended for dead boot repair. Technicians use such packages to rewrite every partition on a phone stuck with a black screen or bootloop after corruption. The scatter text file tells SP Flash Tool or a service box where each image lives in storage. Extract from this volume once parts 2 and 3 sit beside it, then confirm the U2 level on the device, since the name gives no exact build string.
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.
