Dead SKHynix NVME SSD Need Recovery

So i got this NVME SSD that died on me recently
I've searched through PC3000 Support and found out that SK controllers haven't been supported yet

I think the only way to recover it is to swap NAND or whatever components that broke on it

I wanted to know if it is possible to do that???

Its the SK Hynix PC401 NVMe 512Gb
Main controller edged info: 88SS1093 BTB2 113N700 05JW 1812 B1P (Marvell)

Lots of Thanks!

Have you tried the other 1093 utilities ? If it's going into safe mode then nand swaps are pretty much pointless. Have you done the basic checks electrically?

H9CCNNN8JTBL is an SDRAM, not a controller.

I can show you the power supply test points if you can upload a better photo.

Looks like the controller may also encrypt the files, so again, swapping NAND chips will not work.

Hello Everyone!

I have a similar NvMe that won't get recognized and I would appreciate any help. I want to get data off it.

So far I have checked for major voltages on the inductors and they seem present for some time and then they dissapear. While the voltages are present the circled chip is getting a bit worm along with the controller.
Then it seems to cut off power.

What do you guys think?

Measure the resistance between ground and each of the inductors.

Does the 1.7V (1.8V ?) supply disappear too? If so, then there may be an e-fuse or current limited load switch near the 3.3V input which is shutting down due to overload. Can you tell us the markings on the e-fuse?

Can you tell us the markings on the circled ICs?

Resistance on the inductors is normal, After 30 seconds of plugging the disk all voltages including the 1.8 dissapear.

Please check images for the markings. Thanks for your time.

"1A" is a MOSFET, not an e-fuse. There should be 3.3V on both Drain and Source.

Thank you! Cannot find anything wrong with the above chips. They seem to work normally for the time the voltages are supplied.
You are totally correct for the 1A. I wrongly assumed its an efuse based on its location and my limited experience with the normal SSDs.

Well, i can't see anything else looking like an efuse. What about the chip that is getting warm marked with MAY?
Plugged to an amp meter the disk consumption is like 400mAmps till the voltages disappear and fall to 0.

"MAY" is probably being overloaded by the controller. I expect that the drop-out is due to an overloaded 5V-to-3.3V DC-DC converter on your adaptor PCB, in which case you should see this voltage disappear from the "1A" MOSFET.
