Mtk simply Easy way
 

I m new with easy jtag.
I have a phone with mtk chip.
While I was flashing with sp flash tool. It's not writing userdata.
Now phone is detected buy USB but not power on.

With easy jtag what is simple way.
I remove emmc. I got emmc socket.
I want to know complete procedure to make it alive.
I have scatter file.
Any video or step by step.

if you device have non-sign firmware, you can write in at EasyJTAG Plus software via Write by Vendor - Mediatek

1-read rom2 , rom3 , and extcsd if you have not formated it
2-check emmc smart report if it is abnormal or read only than make gp partition
3-full erase
4-write rom2 ,rom3 and extcsd
5-select write by vender select MTK and write scatter firmware
