i had rooted my r2d2 droid2 with the z4 and played around with some of the things you can do to a rooted phone. and well, i decided i didnt like it and wanted back to plain old r2, and well, i didnt make the original back up image or whatever so i dont have my original os. and in the process of trying to following the "help" on here about putting froyo back on my phone, i know not the same as r2d2, but i cant find the r2d2 reboot. but any way, now all my phone does when i turn it on it say "bootloader, d2.37, code corrupt, battery low, cannot program." i cant get it to charge anywhere. if pluged in to the usb, the little light is on, but its been plugged up for 2 hours and no change. can i fix it?
