My Xbox One (original) boots to the troubleshooting screen; if I select "continue" it just reboots to the troubleshooting screen.
Selecting the factory reset option (either keep games option or complete reset) also just boots to the troubleshooting screen.
The only thing that works is doing a power reset (ie unplugging and leaving off for a few minutes) and then factory reset using USB. This works flawlessly and the Xbox works fine (albeit I have to start from scratch including re-installing all my games!).
If I use the "instant on" option then I am able to use the Xbox without any issues. But if it decides to do a complete shutdown for whatever reason, or I use the power saving start-up option then it just boots to the troubleshooting screen again and I have to go through the whole factory reset using USB procedure again.
Pretty sure I've tried all "hard reset" suggestions I've found searching the internet. Thinking of selling it as faulty and getting an S, but before I go down that road (will probably talk myself into an X I can't really afford!) I thought I'd try here. If anyone has any ideas or has had the same problem would appreciate any input.
Many thanks!
