How to Update Verizon Galaxy S3 to VRBLK1 Android 4.1.1 Firmware We will not be held responsible if anything goes wrong. The methods and procedures discussed here are considered risky, so try them out at your own risk, and make sure to read each step carefully before attempting anything. Do not try it on any other device, not even on other variants of the same device. The procedure described below is only for the Verizon Galaxy S3. Read the step-by-step guide below to flash the new VRBLK1 Android 4.1.1 firmware on your Verizon Galaxy S3. Also, you might need to wipe the data on the phone in order to make the firmware boot up, though chances of that are highly unlikely and the data can be backed and restored if necessary. Keep in mind that since this is a pre-release firmware, there can be some bugs and issues present, so you shouldn’t be flashing the firmware if you aren’t okay with testing out beta software. This is the latest in the string of leaked firmware, and since it is an official firmware, it won’t increase the flash counter on the device either. However, we’ve seen multiple pre-final firmware get leaked for the phone which have let people get a taste of what’s coming in Android 4.1, and now a newer firmware has come out, with build number VRBLK1. But then again, Verizon isn’t exactly known for being timely with such major updates, so it isn’t really surprising that people are still waiting for Jelly Bean.

The Android 4.1.1 Jelly Bean update for the Verizon Galaxy S3 was rumored to be set for a rollout by November 16th, but unfortunately, that day came and went without any word on the update from either Samsung or Verizon.
