i'm unable manually force l830 recovery mode (power + volume button), phone reboots before enter recovery mode.

what do? can send in service?

* moved mobile devices

turn phone off, hold 'volume up' , press start button. lightning bolt , gear icon should show on screen shortly, release 'volume up' button. phone in state can use windows device recovery tool.
