How to fix the 100% CPU Usage Bug in a rooted Android 4.3 device

nexusae0_wm_Screenshot_2013-07-25-16-02-41Alright folks, if you have recently updated to Android 4.3 in any way (either by an OTA update or flashing it manually) and rooted it then this article is definitely for you. For your information the file you used to root your device comes from Chainfire and is called Chainfire’s SuperSU which kind of just works around the restrictions placed by Google in the recent update.

Anyhow, as it turns out the Chainfire SuperSU was causing problems for many users as it often causes the CPU of the phone to spike and eat up 100% of its resources. Normally, we would had advised you to revert back to your previous ROM but apparently this time around (and after a week of delay or so) Chainfire has come up with a solution to this problem by providing a simple .zip file which you can flash manually to your phone to remove the whole problem.

The whole procedure is really easy (especially if you are someone who has rooted his phone) and doesn’t really take long. So our advice to you would be to flash the file (included in the link at the end of this article) as soon as you can. For those of you who aren’t really quite sure what to do, here is a short and sweet guide on what to do.

  • Download the .zip file from this link
  • Reboot into Recovery (either by using your computer via adb, “adb reboot recovery” or by the manual method)
  • Depending upon your custom recovery mod, flash the file. (For TWRP put your recovery in sideload mode and adb sideload UPDATE-SuperSU-v1.43.zip, you can do a similar process for CWM Recovery as well)
  • That’s it you are rooted and this time around there won’t be any extreme CPU consumption to worry about.

Disclaimer: As always we take no responsibility for any damages that might be done to your device during or after this process. Happy Rooting Everybody.
