I need to restore my phone to stock!!!

view story

http://androidforums.com – The micro usb input on my phone is broken, so I can't charge it and it is completely dead. My warranty is still intact, so I wanna take it back and get a replacement, but my phone is rooted and has a custom rom installed, so they won't take it back unless I revert it to stock. I have the backup on my USB card, and I know how to do it and everything, but as mentioned before, the battery is completely dead. I thought I'd have at least a little bit of juice left to try and revert it, but my phone shut off about halfway through the restoration process. Any way I can get a little bit of charge int (General)
