I have tried so far:
- Recovery mode
- ADB
- Fastboot
Recovery mode won't boot and ADB and fastboot don't show it connected.
It is outputting at 4096x3840 24p and the TV is showing an input but no luck so far.
I tried the manual update method to update to a beta that may fix the issue but I can't tell if it's installing from the USB or just sitting there. The recovery menu has popped up in the past hour but I could not select anything because when I pressed down to select factory reset the box went to power off and I didn't notice and pressed ok.
Any help will be appreciated. Thanks!
Edit: I already contacted Xiaomi support a while back and after a couple of months they said that they are still working on it.
Edit 2: Thanks to everyone who helped fix it. I used a powered USB hub with a keyboard holding A + B and then it booted into Android from there I used a USB male to male cable to boot into recovery. Next I installed the 1035 update file using the Xiaomi_update file. After that everything works perfectly!
Afaik nougat bootloader needs a keyboard to select anything in recovery. To me it sounds like you installed nougat, the bootloader took, but not the full rom and now it's broke because of that.
You can put 1560 on a USB with a file that will install the firmware when recovery detects it, no keyboard needed. Marshmallow recovery works fine with the remote.
