1. Download: your Stock Firmware from https://samfw.com/

Extract it with zip util.

[ note: I used only old Firmware-T225XXU1CWA2, cause it can downgrade from A13 to A11 for my DJI-Drone .)

2. [Download : KSU boot.img ] + Patch_recovery_for fastbootD.img + Patch_vbmeta.img

Note: how2 patch Sam recovery here. https://github.com/Johx22/Patch-Recovery

create 3in1.tar for flash with USERDATA Slot.

( you should make recovery-vbmeta patch by yourself.)

7. Debloat (delete its from system by..Root FileManager about 600M.)

*** Trick..if you can not delete it directly then move it to another partition such as sdcard before permanent deletion.

***( You can make it RW again when you finished Factory Format this ROM.)
