Somebody please help me!! i have an acer iconia a500 and the power button is stuck and i want to send it back to acer so they can fix it...there is only one BIG BIG BIG problem...i had it rooted and installed a 3.2 rom then the power button got stuck and i was stupid and used iconia root to unroot it not thinking of the rom on it..now i am not rooted and have the basic recovery image(because i was stupid and flashed it back to the orignal with another app) and i cant find a way to get the rom back to stock..all the ways require the power button i have yet to find a way to do this via adb because i have the original recovery...someone please help me!!! thank you
