Phone Bricked/Won't Turn On topic

I've been trying to partition my External SD card so I can use it for Link2SD. I don't have an SD card reader so I tried using the adb + parted command. I was following this tutorial but then I realised that /dev/block/mmcblk0 was my Internal Storage and not my external SD. I deleted the first 5 partitions on there and my phone isn't charging nor turning on even though it's fully charged. Have I completely broken my phone?
