That may not work as modified software will be detected you may need to manually flash your phone with a .ftf firmware file using Flashtools

Even if bootloader is not unlocked and no custom ROM installed?

Did you flash custom ROM or not? Follow Thommo's advice and flash official ftf.

Even if you flash an older firmware - once you connect it back to PC Companion you will be offered the latest upgrade available - For Alex, Rooting changes the kernal and if the kernal has been changed then it will be detected as modified software

Ok Thommo,but I remember people being rooted and when they were offered an update,it could be done but the rooting was gone.Where is the difference?

I have tried this and is does fail or it will say could not verify - When updating manually via Flashtools they would untick a box but Root would still be lost - Now we use .ftf files that have been deodexed which allows root to remain

Yes you will but if your bootloader is unlocked then you will also need to relock it again you can use Flashtools for this by clicking on BLU and then follow the instructions to relock it
