[Nexus 5 General] @GrayFox2154:
Guys i need help here...

Hello everyone, if you are reading this thanks for spending your time helping me out, i will do my very best to pay it back :)

So, my brother's Nexus 5 just got bricked last week for apparently no reason,when he went to sleep and left his phone charging it got stuck into what i believe is a bootloop ( keeps stuck on that flying colors animation for more than 7 hrs. ) So he handed it over to me for trying to fiz it but i've been throw a huge list of problems here...

First of all is that i can't enable USB Debuguing from the developer options since i can't boot up the phone,and i know that one of the very first steps to flash a factory image is to enable it.. My question here is if there is a Linux command that i can run on terminal so that i can enable it... (NOTE: I do already have TWRP installed + obvious unlocked bootloader).

Another problem that i've faced when trying to flash CYANOGEN 12.1 ( which also gets stuck on boot animation ) is that when i flashed it, TWRP displayed some kind of error saying : "E: Unable to mount "/persist' " and i don't have a great feeling about it,i think that this my be the cause for all this mess..

So could someone PLEASEEE guide me thorugh this, i really want to fix it but i am kind of new to this "part" of the android world.. If you help me,just say what you want in the reply that i will do my best to pay it back ;)

PS: Sorry for any misspelled words,i am from Brazil...
