@yug said: 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. I tried it. erase all, and it's work
