Jmicron JMS-583 NVMe/USB 3.1 Controller Latest Tools + Firmware

SUCCESS (partly)
I used an older version of the FwUpdateTool (File version 1.19.16.49) and was able to flash JMS583_00.02.01.04_Bus_Power
Note: it took SIGNIFICANTLY LONGER (maybe 10 seconds or more) for the process to complete, eg. show the "Power off and on" message

After re-powering, this version show the following info:

• UASP DISK:
  <<UASP>> JMicron Generic
• Firmware Ver.:
  00.02.01.04
  before it was "65.02.01.04")
• Flash Type:
  PUYA

Also, the enclosure presents itself as "JMicron Generic SCSI Disk Device" in Device Manager

When I run the previews FwUpdateTool (File version 1.19.17.6) instead, it shows the same info.
 

SUCCESSFUL (fully)

Re-did the flashing with the older tool and my initial backup - only took a smooth second (as I had previously experienced) and was successful
The Firmware Ver. is back to where it was (65.01.00.02)

Still, the device is not recognized AT ALL by my MacBookPro - sigh!

I think now it is the right time to return this piece of broken hardware and try to get it replaced with the RTL version of it

THANKS A TON @Shonk, @Laroldski and @dw999
If only there was something I could do for you guys in return - let me know
 

Sounds like VBS + Secure boot was causing the issues with the flash
VBS stops direct hardware access that some tools dont like

If that was true, why was the tool able to successfully (I actually restored the enclosure from this file) create a backup AND perform a flash (although that led to the issues) at first?
Also, why was I able to perform multiple flash attempts with the other tool?

No, I highly doubt that VBS and/or SB had any influence in my case.
I prefer to believe that these JMicron devices are simply of low quality.

If only I hadn't reassemble the darn thing I would probably try and disable VBS.
 

@Andrew77 Check your private message's I sent you a few suggestions to a few enclosure's that I use that have the RTL9210 and RTL9220,I can also supply you with the correct firmware and configure files for them.
