KSG60ZMV256G TC58NC1000 - rebranded Phison PS3110

For this model chip-off is possible.

Thank you, that could be another way to explore

The only thing that occurs to me is that you could try to find the NAND R/B pin(s) and short one of them to ground during power-on. These pins are open drain, so no damage should result.

Thank you.

You mean 4 GB DDR 3 or the two Toshiba NAND?

I expect that each NAND would have an R/B pin, perhaps shared, and this pin would be pulled up to 1.8V via a resistor.

I don't know what would happen if you were to "defeat" the SDRAM.

OK, I'll investiage each possibility and see what I can do. If I have success recovering data, I'll update this post.

Chip-off - no result. Device was encrypted with Bitlocker. Game Over.

Well,
Chip off possible in PS3110 , Its interesting to know ,If you can built a file system try UFS pro to decrypt bitlocked partitions ,If the key is somewhere they do this on the fly i just had a case of a Kingston A400 BTW .
