well, this is weird, you are the second user in a weeks time to report this kind of issue. Maybe nokia has released some kind of something that won't allow this hacking method anymore...
theres nothing else I can do, probably some of your system folders are messed up. Hard reset should fix this, but you will loose everything on ur phone
If RP+ gives you error "E:/sys/bin/patcher*. LDD not found!" then you have used wrong QuarantineDrivers from first step. Go back, and start all over again with the correct drivers copied!
@sabiin, either move the installserver.exe to E:/sys/bin or take a look at this tutorial (better description, almost the same method (different antivirus)):
well, if that particular installserver you copied didnt work, try other one. Also maybe you should restart phone in order for RP+ to notice any changes
