today I f'ed up.
I was trying to flash recovery from my phone and "su flash_image recovery /sdcard/recovery.img" wasn't working.
So I googled around, and stumbled upon this instruction: "dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p18"
of course, being the idiot I am, I followed the instruction... and to my great dismay, the direction was for verizon S3
So... I went to the correct forum and stumbled upon this: "dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p20"
and now that I got CM10.2 booted up, I have NO signal whatsoever.... I tried ruu flashing the radio files to no avail... help
