ORICO are one of the manufacturers that change their chipsets without changing the products model number, so I can't say for sure if it'll work.
I know that some popular enclosures from UGREEN, POSUGEAR, and ORICO are currently using the RTL9201, ASM225CM, and ASM235CM chipsets, and all of them seem to have issues. So that might be something I'll look into further over the next month.
Yeah, you could just call it a day, since the loader shouldn't randomly become unresponsive when running under a cIOS.
The difference is the base IOS. For cIOS 251, that's IOS 58, meaning it's a customised version of IOS 58.
