I dunno if it helps, but I never got to 7. Tried it but lost 22.214.171.124 and then found support on another post and now successfully installed 126.96.36.199. I can't upgrade to 6.2 now, but everythings working fine. Guess I'll have to wait for 7.0.0.xxx here.. If your BBM has disappeared and you need to downgrade, try these..
