Android 4.3 Update For Sony Xperia TX Leaked?

The EXR (Extraordinary Xperia Romer Group) on XDA-Developers posted something unusual hours back that looks like the OTA update for the Sony Xperia TX LT29i and has the build number 9.2.A.1.131.

Also, any Android 4.3 firmware for this build number is not listed on PTCRB website. However, users who installed this ROM have claimed that the ROM works pretty well on their Xperia TX.

Users have reported that the ROM has Sony’s Smart Social camera and Xperia Themes which have been seen in the recently leaked Android 4.3 firmware for the Xperia T and Xperia SP.
