Available now via PC Companion and, for the first time ime, an OTA update. The OS version is still 4.4.4 but the kernel is updated along with some pre-installed apps. Newer is better, right? n.b. updating will result in loss of root access. Re-root as per .283 firmware instructions i.e. downgrade kernel, root, reflash current kernel. Rooting via FlashTool 0.9.18.x verified.
