It says we can flash via recovery. However, I am having trouble finding the Ubuntu recovery and .img files for flashing. Anyone have a link to these files?

Thanks!

Thanks again. Still not working for me. It says it's booting recovery, and boots to the OnePlus screen. I also let it sit for over an hour just to try, and when I reboot (hold down the power key) it boots to a OnePlus screen (presumably trying to reboot recovery again) and hangs. I let that sit for over an hour and reboot (hold the power key again) and it boots to Android.

I am not sure how it worked for you without booting into Ubuntu recovery to install. I understand it did work, just not sure how it's possible.

Edit: This is resolved for me. I reinstalled twrp and formatted my internal storage aka sd. Once done, installation succeeded without issue.

Ok, so I did it for like a fourth time, and this time when I manually rebooted it booted into ubuntu!

Thanks for this thread. I am having the same issue. While the push does wipe the current recovery on the device, it will not boot Ubuntu recovery to install and just hangs on the OnePlus boot screen. A reboot boots to Android.
