MTK CPU based phones have bootconfig depended where is preloader placed: if preloader write to ROM2 boot config is: Boot configuration [179] / Boot Bus Config [177] / H/W Reset Function [162]: 0x48 / 0x00 / 0x01 if preloader write to ROM3 boot config is: Boot configuration [179] / Boot Bus Config [177] / H/W Reset Function [162]: 0x50 / 0x00 / 0x01 there is no difference where the preloader is. it is important that the bootconfig points to it you can write ROM2 as backup of ROM2 at first page (eMMC general) - Select ROM to access, select file, write binary file you can write preloader file to ROM from FlashTool firmware - you need open firmware at "Write by vendor" tab, select Mediatek, choose scatter file, select partititon to write, write it Last edited by layder; 01-14-2019 at 18:57. | |

If you phone not connect as "MTK VCOM port", you need to desolder eMMC and check it, and write correct preloader from firmware using "Write by vendor" Tab at EasyJTAG plus software, also know as "eMMC Tool Shuite" | |
