please someone suggest how to repair the above emmc, step by step?

Mediatek phone simply flashing via Flashtool software from PC
You can flash only correct preloader via EasyJTAG Plus software from Write By Vendor - Mediatek tab

Unable to flash with flash tool, giving error, that's why I flashed scatter file with easy jtag by vender, flashing successful but still it's showing in logs "warning- health report is very BAD", instead of showing partition, any way to repair that?

Change eMMC (blank with writed boot config) and flash phone via Flashtool from PC

rehot power ic prob. solve.
