ok, I checked that thread and now have additional question for anyone who can have a time and knowledge to answer. obviously there is a new stock rom 12.0.A.2.245 for our bellowed SP. now, I have that older version 12.0.A.1.257 and though I tried updating device firmware I receive message that my phone is up to date. so I assumed this is probably due to some drug deal sony have with my operator ( the one the phone came from) and now for some reason sony would not let me update firmware (yet). so my question is next, actually there are several questions:
A. am I'm going to brick my phone if I manually download and update new firmware via flashtool regardless of sony saying my device is up to date?
B. Is this new firmware 12.0.A.2.245 so much better that is actually worth updating? (this should be A)
C. if i root this old firmware and perhaps install CW as well, and than update to the new one, am I'm going to loose both root and CW, or perhaps only CW after updating? or i will get to keep root and CW?
D. is it better to update and than root, or root and than update?
i hope this is not too much. thanks!
ps. i forgot to say, though my phone came from an operator, it is not sim locked and boot unlock status is YES
