emmc is bad.
you can try repair . but Emmc can dead fully.

Repair 0000 to vtum done Many time, before my emmc shows 0000 now after repair it's shows VTUM but rom2 boot partition 0kb ,I guess I done something wrong while I was making boot partition bootable I was confuse to do 0x1 and 0x48 how to do that.

no need touch partition. just do repair excsd for make bootable partition.
in your case problem with partition size. and from our experience this cant be solved at this moment.

Done

I changed emmc configuration boot1 and boot 2 size =2mb
RPMB partition size =2mb

And now it's writing both rom1 and rom2 perfectly.

Now after repair it's giving me error while flashing there is no pit partition ???

how u write extcsd from working phone?
couse some time after change boot partition the device either not goes to download mode or stock on logo and cant flash.
due to my experience write extcds from working phone if not solve change emmc

mostly phone's from 10 out of 8 done via mmc dump after. phone goes in download mode flash with pit and any flash file phone alive ,very rare easyjatg need for boot repair..that's my experience,done nearly 25 phones .22 with mmc dump and 3 with easy jtag.

Remember there is certain pit file working
You have to check one by one which is working one ,
This is the only secret is right pit file for flashing to make your phone alive again good luck everyone.
