Hello, I foolishly tried to update from 10.1.0 to 12.0.3 on sxos v3.1.0, using choixdujour, Now I have caused a booting problem. The sd card I used will no longer boot. However, a duplicate card made before updating will boot, although the machine now takes much longer to finally turn on. I reformatted the disfunctional sd card and created a new emuNand, the same way I have done before, but it will still not boot. I can get into RCM mode and into hekate with this sd card, but no further than that. When using the original duplicate sd card, it will launch into firmware 10.1.0. I have a backup Nand, in case...I plan to take the machine to a professional for help, because I dont want to make it worse, but any advice or insight would be greatly valued. Thank you.
