New update is not getting installed on low storage devices as it requires whopping 740MB free space on phone memory. With System taking along 2.67G and another 300M with system apps this much space is impossible. I think in previous GDR1 update MS allowed updates to be installed through SD card. Now the phone is in cyclic process of installing update causing battery drain. (it stops installing for sometime and after a phone restart process starts again). I don't want to perform the hard reset..
