NVME USB drives Realtek RTL9210/RTL9220 Firmware Version 1.xx

after the firmware update unplug the disk if still nothing this is weird

After long time spent on googling any info about serials I haven't found a single word about it, but I finally figured it out myself. I am using 9210B-CG box and it has 2 different serials - UUID (which was zeros) and serial from config which does not appear anywhere but in flashing tool (that is probably the same for other 92xx series devices but not sure).

1. It is possible to make config serial to appear as disk drive serial in different disk info tools such as CrystalDiskInfo. Edit your config by adding parameter CUSTOMIZED_DISK_IDENTIFY = 0x1 and reflash - after that any software on PC will show config serial as disk drive serial, also if you have SCSI_PRODUCT and SCSI_VENDOR parameters defined they will also show up as disk vendor and disk product name (previously those were also shown only in flashing tool and in WMIC). Useful if you want to somehow hide your real disk info.

2. However, config serial will not appear in WMIC - if you run wmic diskdrive get name,size,model,SerialNumber command in Windows cmd, it will still show "0000000000000000" as drive serial. It is device UUID which is not possible to be changed in firmware config, but there is a way around - you can hex edit the firmware itself. UTHSB MPTool Lite ver. 1.14.8.0610 or below is required - newer versions have CRC32 check for firmware file and if you try to flash modified file it will semi-brick your device (does not work but can be reflashed without shorting pins). Save somewhere original .bin as backup, open your firmware.bin (not the GD one, you don't need to touch that at all) file in hex editor and find those 16 zeros in it - for example RTL9210B 1.32.49 firmware file has them at address 00004ea0. Replace them with anything you want (just in case better keep it the same length 16 symbols so you won't break anything else in firmware). Save, choose edited firmware file in MPTool, flash. That's it - device UUID changed and WMIC will show your new UUID if you run the command. Dump from MPTool will still show UUID as "n/a" though, that is normal.

Hope it will be useful for users who are facing the same problem as me.

thanks for the information 

Hi, I bought this ssd case www.orico.shop/en/usb32-gen2-usb-c-m2-nv...ual-p-138852713.html should have the Realtek RTL9210b chip, currently connected to usb type C the speed does not exceed 460mbs, I wanted to update the firmware to see if the speed increases, which firmware should I use? Thank you

Hi

Check already if you are well connected to a USB 3.2 port (see above)
After also checking that you have a Realtek RTL9210B with the utility provided with the firmware
