Did something stupid. gpt.bin

Hi,

I think i did something stupid.
I want to sell my moto x and therefore i tried to relock it.
Somehow i was a little drunk and flashed 4.4.4 on my moto with 5.1.1. Unfortunately i used some instructions which also included flashing gpt.bin. During the process i realized that this might be a bad thing. Now all i can boot is TWRP.

Any hint how to get a proper Lollipop running on the phone to sell it?

Can´t find any 5.1.1 gpt.bin and the other files needed to flash with fastboot...

thank you very much in advance!

Stupid question, sorry, but I bricked my phone and I'm stumped...

So I followed the instructions here i found on google by searching "how to how to root s6 edge plus", second link down... and it was a bad idea. Now my phone will boot, and show the lock screen for a second or two, and then just reboot. So I'm stuck in a bootloop. I'm fairly new to the android rooting scene (I've been jailbreaking iPhones sice 2007). What do I do? I tried restoring the default firmware in Odin but it didn't work. HELP!
