I am trying to write a custom recovery (TWRP) using SP_Flash_Tool but I get a Status_preloader_invalid error. The device is "OPPO F1S" with chipset MT6755.
Here is a screenshot of the error and the scatter file I am using. https://drive.google.com/drive/u/0/folders/1nyQQKPbYot_YxWwHN5lScNAEq84h-o3A
I tried to create the scatter file using Mtk_Droid_Tool but the creation button was greyed out (MT67xx is not supported) so I found a scatter file online
