How to downgrade mtk ufs firmware with easy jtag plus

After Downgrade
How to downgrade mtk ufs firmware with easy jtag plus.
for example i have selected vivo v23 5g phone.
you may know that easy jtag plus ufs doesn't support scatter file,
even it doesn't show preloader partition when you scan chip.
otherwise you will notice that ufs chip mtk firmware shows two preloader.
as many technicians know that...
only preloader pertition exists in lun0 & preloader_xxxx_64 in lun1 part.
if anyone...
directly write prealoader in lun0 & prealoader_xxxx_64 in lun1 part it's totally wrong,
so you must have backup downgrade dump (lun0 & lun1).
