Do I need to relock the bootloader to use PC Companion for latest stock?

I want to go back to stock for now Xperia J, and do I need to relock the bootloader or just use SEUS/PC Companion to flash latest stock?
Thanks in advance.
If you are on a custom rom then you need to download the stock ftf file and flash it using flashtool to get PC Companion or SEUS to work.
You don't need to unlock bootloader.
Yes you need

I'm asking about re-locking it, it is already unlocked. Can I have more opinions? I don't want to brick the phone.
download the ICS ftf, flash, then relock bootloader.

Sony PC companion requires locked bootloader to work bro.
Since you are already on unlocked bootloader, you can just download the ftf file you want and flash it using flashtool. Using flashtool you can flash firmwares on both locked and unlocked bootloaders
You need a locked bootloader and any stock ROM to update through PC companion.

You dont need to unlock your bootloader,just find a ftf and flash it with flashtool...there are many guides on the internet
Thanks for the info, can you provide me a link where I can find official Sony ftf files?
How secure is to use random ftf file from the internet? I use online banking on my phone, so I want to be sure that is secure.

There are no "official" ftf's...You can make one by using xperifirm (i doubt the kitkat files are still in the servers)
ftf in xda are trustworthy most of the time
Thanks, can you or someone else send me the theme where I can download the ftf file for my Xperia from xda?
Don't think there is any KK ftf's left on expirifirm Sony usually remove them pretty quickly. There's bound to be one on here somewhere. I think I've still got a pre-rooted KK zip somewhere for the D2303 lte, also I don't know who told you that you need to unlock your Bootloader to downgrade/use flashtool, you don't it'll work on totally stock unrooted devices. You must however wipe user data+cache+appslog when downgrading from lollipop to KK and when Updating from KK to lollipop via flashtool.
