Killed My Phone

So just now I wanted to install a custom rom since mine was bugging out. By mistake I wiped the phone(including System), so stuck in bootloader I tried to flash a rom which failed, then trying to get back in recovery I pressed up volume, and now I'm stuck in boot loop.
Also a Few Facts- I broke my Volume Down Button(That means I can't get back into bootloader)
Any Suggestions? Pls :(
