A lot of devices have been receiving the Android 4.3 goodness during the past few weeks far before its official release. It was just last week that the Google Play Edition Galaxy S4 (GT-I9505) received a leaked Android 4.3 ROM (build JWR66N) and it didn’t take much time for XDA recognized developer Chainfire to release a root method for this build. This ROM being an early build, was pretty basic and had some issues. Now we have a newer, improved Android 4.3 build leaked in the wild (with build ID: JWR66V) for the very same device from XDA member karoolus (system dump alone). And another XDA member, friedrich420 made a flashable zip out of it for others to enjoy.

Most of the users had problem with the first build while unlocking the SIM, but the developer, in this new ROM has managed to bring up a solution for that and we’ll be coming to it at the installation steps. The ROM is fully stock, pre-rooted (with chainfire’s method for the previously leaked Android 4.3 build), deodexed with busybox installed and all .apk’s zipaligned.

For those who prefers to have an untouched version of the build, head over to this thread on XDA for the odexed and unrooted basic build which can be flashed through TWRP/CWM. If you have any questions using CWM, move over to our post on it. The flashing is very simple, it just involves doing a backup, wiping the data and cache , flashing the ROM, flashing loki-doki (for AT&T model) and rebooting.
