Trying to root my thunderbolt after .9 update. I have already downgraded to the. 5 but stll are unable to root. Revolutionary even said root was achieved, but root checker said my phone wasn't rooted. Also tried tb autoroot and it keeps failing also. Says inappropriate iotcl for device and tells me to pull battery and try again. Any advice?? Phone is from insurance, don't know if that matters?
