Yes - in theory.
But to put in perspective - the ums-loader is close to max size for IRAM - so we are very limited in what we can run there.
Also - without being able to mount the emmc we can't do a backup from there.
I presume your GPP, BOOT0 & BOOT1 menu items are grey in ums-loader?
(which means there was a problem connecting to the emmc).
I'm currently working on converting ums-loader to a bit of a diagnostics tool - so that those of us that have this problem might be able to get some more information.

That screenshot looks just like mine - the app is unable to mount the emmc.

I like your train of thought.
As a test I put in a code snippet for starting the DRAM - that seems to work ok... but I didn't think to actually run a read/write DRAM test. I'll add that to my list for the changes I'm making to ums-loader
I can read and write the nand with that payload.
I already did a backup, and restore the boot0/1 before that i flash erista boot without being notice about it.
