Some weeks back I installed the latest version of LineageO S: 14.1-20170209-UNOFFICIAL-onyx on my One Plus X phone. After playing around with it, there were a lot of issues in the new build. So I decided to uninstall it by opening the Developer Options and tapping 7 times on the build number, but nothing comes up.

Below are the things which are not working in the new build:

  • Tapping build number 7 times doesn't unlock Developer Options
  • No notifications at all. I can hear the sounds but no success to show notifications
  • Google Play Store updates & installation suddenly stopped
  • Reset everything option not working

How to open Developer Options so that I can activate the bootloader & install the stable ROM?

    Can't you just use adb reboot-bootloader from a PC?

We have a potential XY problem here...

Instead of trying your utmost to get into developer options, just power off the phone fully, then use the key combo POWER + VOLUME_UP to boot into bootloader, from which you can start tackling the problem in ways you'd like.
