PTCRB finally posted a newly certified Android 4.4 KitKat firmware for Sony Xperia ZR with build number 10.5.A.0.230. The 10.5.A.0.230 firmware build version is now the official upcoming update for Xperia Z, ZL, ZR and Tablet Z expected to be released in mid-May.
Sony Xperia ZR New Firmware
PTCRB certified a new Android 4.4 KitKat firmware for Sony Xperia ZR with build version 10.5.A.0.230. It is the exact firmware build version for Xperia Z, Xperia ZL and Xperia Tablet Z which was certified few days ago.
PTCRB certified the new firmware in May 7th as an incremental upgrade to the unreleased 10.5.A.0.227 build version that was certified in April 29th. It is compatible with Sony Xperia ZR C5502 and C5503 models.
Android KitKat 10.5.A.0.230 Build
In May 6th, PTCRB certified 10.5.A.0.230 for Sony Xperia Z, Xperia ZL and Xperia Tablet Z which is also coming to the Xperia ZR smartphone. It succeeds the previous and unreleased 10.5.A.0.227 Android KitKat firmware version for all four Xperia devices and contains incremental upgrades due to the slight change on the firmware numeral.
Moreover, 10.5.A.0.227 to 10.5.A.0.230 certification may indicate several issues and could be the primary reason why Sony Mobile did not release the earlier firmware version. According to XDA forum member DooMLoRD, 10.5.A.0.227 suffers from certain lags once installed on Xperia Z unless you tweak something inside the Developer Options.
DooMLoRD managed to boot the 10.5.A.0.227 firmware on a commercial Xperia Z model even though it is only designed for ?brown devices? or developer models. The said firmware is under testing stage and likely to feature several changes that may or may not be present on the final version.
Since PTCRB already certified a new firmware for Xperia Z, Xperia ZL, Xperia ZR and Xperia Tablet Z, we can expect several improvements from the earlier build and upcoming rollout as early as mid-May.
