Pantech Breakout/Jellybean.zip??

You should think about a newer phone if possible.

 

Was the ROM on some free sharing site like RapidShare or something? Those usually expire and will be deleted after a while, like six months. All you can hope for, is that someone reading this still has the file and can kindly upload it, or send it to you.

 

There's one right here on AF from 2012, but the free MediaFire download link has long expired.

There's probably just not the developer and community interest in a rather old budget device like that these days. So I think all you can hope for, is that a user somewhere actually still has the file you need. That's happened before, someone was asking for a "long lost" custom ROM for a device, and a few weeks later someone else reading the thread, replied and did still have it.
