HTC Butterfly 901s SOFT BRICKED

Guys I need your help

My phone wont start-up because its stuck in a boot-loop.
I can go into bootloader just fine but cant seem to be able to access recovery though I have flashed the correct custom recovery for this phone. When trying to enter recovery mode it hangs first and after a minute or so it restarts itself. also it has a red message at the bottom "This build is for development purposes only... ***"
The phone came with jellybean 4.2.2 and i wanted to upgrade to lollipop because the phone had been infected with a malware

if ya'll could help me find the correct RUU or boot.img for this phone i'd be grateful... or rather still tell me how to I can flash a new OS to this phone using a PC tool or get into recovery mode.
