[Saferoot] worked for Razr M Xt905

works for my 98.21.7.XT905.Retail.en.AU version too.

I can't get the root method at pinned thread worked on my Razr M JB 4.1.2 (98.21.7.XT905.Telstra.en.AU)
the following root method works for my Razr M
[ROOT] Saferoot: Root for VRUEMJ7, MK2, and Android 4.3 :
p/s: appreciated if anyone can update that thread that Razr M with 98.21.7 also works :)
