Hi My Razr XT912 will not update from version 2.3.5 the system version is 6.11.910.XT912. When I try a system update the message says my device is up to date. Contacted Motorola and they say my phone should be on JB and they pushed an update to my phone but it does not work. Will the all in one utility posted on this forum let me update to JB from my version? Thanks for your help.
