So I bought my Nexus 4 last month expecting that it'll have a 4.3 OS version. However, my sister accidentally updated the version.

Now, I would like to downgrade my OS version. Following this guide:


what might be the possible failing scenarios and what am I going to do if that happens.

    I am curious why you want to do this? The bugs mentioned in that article have been addressed in the update from 4.4 to 4.4.2. Feb 7, 2014 at 4:58
  • That is not correct. I have 4.4.2 and I am suffering from all the bluetooth related bugs (service crash and bluetooth disconnect/reconnect crazyness). Plus on top of everything the new dialer and few other things quite suck. Big time. For the first time ever, I am planning to downgrade Android.

  • Well that guide seems right, just reflash stock nexus 4 rom and you will be fine. However there is a possibility that you may enter boot loop/softbrick but thats easy to solve and very rare. I recommend you following this guide it's from google tho : developers.google.com/android/nexus/images Sorry for my bad English if I made some mistakes, becouse English is not my mother tongue.

Once you unlock the bootloader, the only major risk you may face is bricking the phone when loading the aosp images of a previous android version.
