1. Run dumper.exe (in case of Unsafeshit 2.51 click OK or hit enter after message appears)
2. Browse the HD and select the Safediscv2 protected file (99.999% of all cases its the main .exe, experts say)
3. Click Open
4. wait about 10 to 60 seconds until message appears that .data.bin was sucessfully created and click/enter it away
5. Run Rebuilder.exe (Unsafediscv2)/ 2_51_Rebuilder.exe (Unsafeshit 2.51)
6. Select the data.bin file ( <name of .exe>.data.bin ) and click open
7. wait until message appears and click/enter (yep, yet once again) it away
8. Your .exe is now ready. Its named sdv2.testme.exe. Rename it to the name of the original .exe and test it.
This is how you do it. Hope it helps.
