Hi all.I'm new to android central but i've done roots (on my droid x) and am familiar with android in general.Here's my problem.I bought a new Razr HD it has stock jb 4.1.2 version 9.18.94 now to root my phone I believe ( correct me if I'm wrong) I must have at latest,version 9.18.79 to use motochopper 1.3 to root...unfortunately I don't know if it's possible to rollback my version to 9.18.79. Please let me know if it's possible.
