I have a Miyoo mini plus Version 202303262339(im going to assume this version is up to date) I brought a new reader and micro usb 256 card that i formatted using my laptop....no special program. I downloaded Onion OS 4.2.0 unto my laptop then transferred the six files to my usb card. I transferred my USB card to my Mini plus, and turned it on, the new OS isnt loading, I continue to get the default OS that came with the Mini Plus. Any help will be greatly appreciated.
