[Q] really need some help please. totally borked my new moto x dev edition

[chnacat]

just got my brand new developer edition moto x. successfully unlocked the bootloader, successfully installed TWRP recovery, successfully installed SuperSU, rebooted the phone and stupidly tried to update the software through the phone's system software update, got stuck in a reboot loop, and then attempted to flash a ROM. realized i bricked it. now i can't sideload a ROM and every time i try, i reboot to recovery, use the adb sideload, it looks like it's loading, phone says successful, asks if i want to reboot and then tells me that there is no OS.

i am brand new to this, and i've clearly effed it up, but really not sure how to fix it.

i attempted to follow the instructions here http://forum.xda-developers.com/moto-x/general/guide-moto-x-return-to-100-stock-using-t2446515 but using the step two method but got to fastboot flash partition gpt.bin and got an error in terminal (i'm on a mac)

i would be most grateful for any help at all. i'm really stuck.

thanks in advance.

First... Boot the phone into Fastboot/Bootloader mode.

What is the version listed on the second line?

Next, you'll want to flash the rom that matches that bootloader version using a slight variation of Option 2 on that link... For example, if the bootloader on your phone is 30.B4 then fash the stock 4.4.2 SBF, if 30.B7 flash 4.4.4.

Start the steps with....

mfastboot getvar max-download-size
mfastboot flash partition gpt.bin
mfastboot flash motoboot motoboot.img
mfastboot reboot-bootloader

then use the rest of those commands AS they are written. yes, you'll be repeating the flashing of GPT.Bin and Motoboot.img, and that is intentional!

When you get back to stock, I suggest you take a few minutes/hours to read and familiarize yourself with what has been written.. Like don't take an OTA unless you have the STOCK recovery. If you have a 3rd party recovery and take an OTA you'll be stuck in a boot loop (to get out, boot the phone in fastboot and from the PC.. fastboot erase cache followed by fastboot reboot will stop the loop, then you can flash stock recovery back on there to take the OTA. Never DOWNGRADE the rom on your phone once you have 4.4.2 and up or you will brick, etc.
