Actually, just see my sig.
is the rom. I am on T999 (T-Mobiles S3) using ATT service. The rom was based off verizons, that has been since ported for multi carrier use. The only thing that could never be removed it seems is the "Backup assistant" thing. However now that I removed all the samsung account, push service and cloud stuff. The "Cloud" also stays stuck in settings now too.
But yea, just got done using battery stats log and found out (Hopefully) what was causing horrible battery life..
is my log file from that, which was all related to the push service constantly waking my device. So after 5 hours, I was already at 50% of my battery.
But yea, those were 2 things not in your installer to remove, the Samsung account (and I dont know if the Samsung Setup should be removed?) and the samsung push service.
Also I dont know if you had this one either.
I came across it too when avast told me it was installed with this rom. So I removed that too.
