cannot Update to OTA Update

[solai_4]

Hi,

i using stock recovery only and i rooted my device. but now i cant able to update to the OTA update while it updating it show warining icon and few sec later it restart

[nick]

I am unable to complete the offered OTA update also. My phone is not rooted.
This morning it offered me the update so I accepted - then I got a message that the update could not complete because the phone was USB charging. I disconnected the phone and tried again but no luck. Have tried rebooting and also manually checking for the update. Each time I am told 'no update is available'. I am 100% sure that the update did not complete the first time. Have tried rolling the date forward a few days, no change. Any ideas anyone? Thx
