How to: Verizon Galaxy S3 Android 4.3 root (ML1 software update from OTA)

Verizon Samsung Galaxy S3 (SCH-I535) is getting old, this smartphone was introduced nearly two years ago but it’s still widely used although not as popular as when it was released, maybe that’s why Samsung still provides an OS upgrade to Android 4.3 with I535VRUCML1 software version, which could be the last update.


For Android enthusiast, the OTA update could be new challenge, since it brings new bootloader and KNOX security features that will make the S3 a bit more challenging to get root on Verizon Galaxy S3 running ML1 (Android 4.3 Jelly Bean).

Fortunately, a fortune seems to still be on our side, because we can still have superuser access on VZW Galaxy S3 running ML1 software from the OTA update. Thanks to k1mu, a dev from xda who found the exploit, he built a tool called “Saferoot” which allows us to regain root after taking the Android 4.3 software update. Although it originally created specifically for the Verizon Galaxy S4 but it can also work great on an older device, including the S3.


  1. In order to have working adb connectivity, we have to enable USB Debugging on our smartphone.
  2. If you are using an older KIES to setup the drivers, it seems you have to install the new KIES 3, it is required by Samsung device running Android 4.3 firmware.
  3. Grab the Saferoot exploit here by k1mu.

      You should Odin back it to stock, with ML1 firmware. Or simply use SuperSU’s full unroot feature.
