SKhynix M+B mSATA SSD not recognized

[canebaycomputers]

SKhynix SC300 M.2 2280 512 GB. There is no doubt this is not working. I've tried plugging it into a PCIe adapter card, USB adapter and now a SATA adapter. In the thermal the SH878104AA chip just gets a little warm. I tested all caps for any shorts and see no issues there. No missing components. No corrosion. My only guess is that this is a controller chip and would need to be replaced? I did already order a duplicate SSD that has that same chip. Not sure if that even works? Does it hold TRIM data? Just not sure on this. I realize this is a M+B key mSATA and I have plugged it up properly into the correct adapters that support it. I do run a professional computer and mobile repair shop but I'm limited on advanced data recovery. I don't have much experience and don't have pro tools. Willing to learn and invest. Any help or advice very much appreciated. Thank you in advance.

Plugged it into Linux box with an adapter.

Controller is not supported by PC3000 for firmware fixes. Linux is only talking to the Jmicron controller in the USB bridge being used.

Probably best to send out to a data recovery professional with tools and experience to handle it, if it is even recoverable at all.

did it get warm when it was in the adapter or you added some voltage somewhere and which ones are the caps to test on a ssd?
does pc3k support those samsung evo and pro disks or which tools should be used to run some hardware tests on it without any harm for the data?
