I have the the new X3 II.
I made a mistake on the flash drive. I meant a micro SD card that I inserted in the X3 II. It is 8gb I only see one slot on this player.
The file I downloaded from Vortex was: X3ii_v1.0_9970b2e-181013.zip, which included: readme.txt & update.upt

Got it.
So the thread you would want to ask the question is located here: https://www.head-fi.org/threads/new-xduoo-x-serie-dap-x20-x10-x3-xduoo-are-on-fire.867522/\
That thread covers all of the new xduoo models, including your X3ii.
This thread is actually for Rockbox on the old (original) X3. That's why I asked about the 2 slots and I didn't recognize update.upt.
Sorry for the confusion.
