Sure when you receive the cable all you need to do is plug it in, and it should boot up just as if you powered it on.also im not the most knowledgeable my self but i have had so many people on this forum to help me I'm just trying to return the favor. If just plugging it in doesn't work try power + vol down method and or power +both vol buttons down,to see if you can get it to power on any kinda way.hopefully its just the battery and you plug the cable in and it comes right on.i think it would be very strange for you to have the same problem that i had and have a bad motherboard, but it's possible. Aslo if the charge port is damaged the cable probably won't work,so make sure to look at it.if it the charge port is damaged and the phone wont come on with the cable you will need to manually charge the battery,or find someone with a RAZR that wont mind you removing their battery to put in yours, but good luck with that lol.lots of people think you cant remove the battery but you can.it's just a little more trouble than popping off a cover and lifting out the battery like on a dx.if you have to remove the battery you will need to have a t3 or t5 torks bit to remove the small screws at the bottom of the battery, then just lift out the battery.the battery has a tab on it that says remove battery pull it and don't be scared to tug hard cuz it will be stuck in with some type of sticky tape,just make sure not to damage it.also i didn't ask if the phone is still under warranty? If so of course the battery removal will void your warranty.
