Hello @amankumbhaniumar Gond​ 

Can you provide more details about the problem (flash the code): symptoms? how to reproduce it, is it systematic or random?

What do you mean STM32F439NIH6 VQ3 and VQ4?

Likely different die out of the VQ fab ?

>>Anyone have Same Issue..

How would anyone know? The description of the problem / issue is incredibly vague.

Assume no one here was involved in the design and coding for your board.

You get an error from a programming application? What program, what error?

STM32 Cube Programmer is the currently maintained application for programming via the ST-LINK pods.

Hello @amankumbhaniumar Gond​,

I suggest using the System loader via ST Link (SWD or JTAG port) for programming and erasing the flash memory. If you could describe the steps to reproduce the issue.
