you emmc may be dead, run "random verify" test, check it
you have error at one address - it may be bad NAND sells

MTK base, don't use usb for vcc and vccq if you are flashing, cpu reset after awhile then loose connection on vcc and vccq..check device manager

Operation: Random verify eMMC ...

If your restore data error occurs - the original data can be found in a folder:
\Backups\RandomVerify\GD6BMB_B60AA813_20191010_135 250

eMMC switching to ROM1
