How to recover data on a recovered flash drive?

Question

USB flash drives

I had a dead flash drive lying on the shelf, which the computer does not recognize.
I decided to reflash it and reflashed it, but now there is such a problem, the data on the flash drive was lost, the flash drive is completely empty, I tried a bunch of software, but it does not find anything.
Is there any way to get the files back from the flash drive, or are they completely deleted?

Answer 1

When restoring, NAND is usually overwritten, so there is nothing to restore there. There is a utility from Transcend, which has the option to restore the flash drive firmware without formatting. If you used service utilities for the controller to restore, then most likely nothing can be restored without disassembling and removing the dump from the chip.

If there is at least something, then it will pull out, if not, then that's it.
