    The service center is very close from my place. I have no idea about oneplus website, do contact the chat support, there is a possibility that they can do it remotely.

    Hi, I was experiencing high battery drain also my device is the KB2000 which was on the global software KB05AA I'm in the UK, so I flashed the European version KB05BA & it's running much much better.
    What part of the world are you in?

    Hi not at the moment, you can only update your version from KB05AA to KB05BA or any other build version you might be on to an higher software version, as you're on 11.0.6.8 OnePlus will only let you update to an higher software version like 11.0.6.9 from their software support page, I've tried it myself.

    Are you leaving all the applications open in the background?

    That's strange, did you miss something? I done it & it only took about ten minutes for the whole process.
    Make sure you haven't missed anything out.

    No I did all the steps that the process required, first downloaded the file from official page of 1+, second moved to root folder, change de extension .jar and installed due local upgrade and always get stuck at 93%.

    I didn't change the extension.jar, all I did was download the update, moved it to the root folder then went to local update.
