Stuck in Stock Recovery WITHOUT use of power button

Recently went about flashing custom rom to phone and ended up in the Stock recovery menu, of coarse without the use of buttons i cant get anywhere... also as battery is internal cannot remove. so at the moment is essentially a brick. I recall being able to use a ADB command or something to reboot from recovery but cannot recall what i was or from where it came... any help would be appreciated.
Also on a side note: is TWRP compatible with P7?? or alternatives???
