Help How to Repair LG870 Boot Loop Using Apple MacMini or Samsung Chromebook Laptop?

[LG870 Boot Loop]

My phone is stuck in a "Boot Loop" and all I see is the Boost Mobile animation and 4GLTE logo in a continuous loop. My only recall of what I was doing before this happened is I was making a backup of my photos and videos to an external hard drive connected to my MacMini (I backup often so I have most all my device content saved). After that I turned the phone on and it began the Boot Loop. My phone is not rooted, it is "as is" from the carrier, no mods or anything. I have reset the phone and wiped all the data and cache using recovery mode. I have not done anything else yet.

I have researched this online and all I found were solutions for:

• Phones that are "Rooted"
  
• Users on Windows PCs

I am:

• Using a MacMini Computer (I have a Samsung Chromebook Laptop also, not sure if this can be used for repair or not?)
• My LG870 is in great condition (no damage, in protective case with screen shield)
• I do not have access to a Windows PC
• I have MicroSD Card I can load file on and insert into LG870

With that being said, is there any way I can repair my LG870 using my MacMini or Chromebook? If so, can someone direct me to where I can find this information.

Thanks!
