I am helping a friend of mine who's machine has been infected with GANDCRAB V5.1. Ransome payment is $1200 USD which is rediculous.
Are the any decryption tool to decrypt file?
Did you try tool for v.5 ?

Ask forensics@bitdefender.com for help
It was not working because 5.1 tool was made available weeks later. The thing is that currently there is a 5.2 version where not tools available.
There is a working tool for 5.1:
