I think there is something wrong on your usb stick
Hallelujah! We have a fix & Jeff Buckley is singing it to me and I can see he's singing it to me on my A/V receiver projecting on my screen .... Phew!!
So Xiaomi have come back to me with a fix that I'm about to paste below. Before I do let me share my experience.
I executed the steps the first time, the projector went into update, rebooted, told me that I had the USB device connected I'd used to trigger the update and asked if I'd like to use as storage or exit. I chose exit. Ran the setup, went to HDMI and .... oh sh!t it didn't work ... same problem ... bummer! Was half way through emailing support again when I thought what if it's that darn USB connection. Ran the update again but this time as the projector rebooted I removed the USB drive. Hallelujah .... the projector went straight into setup and once done I was able to see all my beautiful HDMI devices again
Hey man, did you ever find time to document some kind of guide on how you replaced the fans? I'm very interested in trying this myselfI finally changed all 3 fans to NoisBlockers M8-S3. Top things:
- overall noise seriously decreased, most annoying vibration noise which came from hard contact between fans and chassis completely gone.
NoiseBlocker fans have rubber edges which removes all vibrations coming from the fan. So only natural air noise left.
- when the chassis is opened - I can barely hear the noise. But when I close the chassis - the noise increasing 3-5x. Lots of noise come from the chassis grills when air goes through them. If you'd like to decrease the noise further - need to replace the existing grills with metallic grills. I will probably do it.
- You will 100% lose warranty during fans replacements.
- For all who care about the projector noise - fans replacement is 100% recommended.
p.s. I didn't have time to write detailed post, hope to find 30 mins near future to share photos and important details of the process.
The bottom black part is a rubber ribbon. Can be removed but I left it there.
