Can the LG 870 be fixed?

[AC Question]

A coworker gave me his boost mobile lg870 phone to fix cuz its stuck in a bootloop. i went to xda website and when i type in lg870 it doesnt show up. so i go to all lg devices and i still cant find it. is there another compatible rom that i can use? Also i tried using lg support tool thats not working as well. i tried using lg flash tool that didnt work. i put the freedom F7zv5 on an sd card and went into android recovery and tried to apply the update from the sdcard and it didnt even show up. what else is there to do to try and get the phone out from the bootloop?
