I've recently updated my firmware to fix the battery charging issue, everything went good updating the controller as well. I'm unsure if this is related but 2 days later when I power on the controller the screen stays blank and the fan speed at 100%. The controller will not power off, i just get a buzz when I push it.

Anyone else seen something like this? Hopefully it's not bricked...

Never seen that one and I'm the 5.11 firmware.  My RC is on ver 04.00.0110 with aircraft at 04.00.0111.  I would pull all power including the usb-c charged bottom and power it up with a Wb37 and see if that makes a difference.

I am having the same issue. Stuck on 99%. Rebooting doesn't help.  I am scared to do a firmware refresh since other than the charging thing the SC functions well.  Just received it as a replacement to a malfunctioning SC today.  Any thoughts?
