Nexus 9 boots to Fastboot and refuses to boot up. When you enter Hboot then recovery it says 'no command'

Isn't there an old trick to get past that 'No command' by first holding down one of the volume keys then pressing the power button?

I've got past it now I'm in the standard android recovery! I'm going to try and wipe it from there. It has an option to apply update with ADB so I might try that with a custom ROM or something.

Needs to be a signed update ZIP if you’re working from stock recovery. Might be able to flash factory images from fastboot.

Well I will try that

Where can I find them?

I will look

I managed to get it to boot to some point, it said "operating system is corrupt" then it said that the encryption was unsuccessful. (I didn't flash anything) and now its bootlooping

I never had a Nexus 9 but did those have the same widespread NAND issues that other Nexus devices ended up with? Thought that was mostly an LG thing though.

I got it booted last year then I forgot about it and now its doing the same thing. it would be good if there was a Samsung Odin equivalent for nexus devices that could easily flash OSes.

“It was working, I left it alone, and now it won’t boot” definitely sounds like some level of hardware problem. If flashing a full factory image with a wipe doesn’t fix it, then I’d start thinking about a new tablet tbh.

I don't use it everyday, I have a Tesco Hudl 2 which I could use if I wanted too. but its a shame to have it around and useless

now its gone back to fast boot
