I'm on ihackers 2.1 ROM android 4.3
rooted
unlocked bootloader

I wanted to go back to stock to C6902_14.2.A.0.290
I found the method but I'm not sure if this is the right way http://lionking853.blogspot.co.uk/20...rmware-on.html

and if it is the right way, after going back to stock ROM, will my phone unroot and relock again?

Can I just go ahead and do this or must I relock bootloader first?

please help me since I never done this before, only rooted and unlock that I did.

Thank you so much folks

Restore your TA backup.
That will relock your bootloader, of course.
Then just flash official ftf (you have almost all region here on XDA to download).

Flash 136, don't go to 534.

But remember : flashing ftf through flashtool will wipe everything.(and it should)

So backup all your files.

If you want this only for updating to 136, as I can see, many guys just flashed NUT stock deodexed 136 without wiping anything and it's working.

Well it depends on what you want to do! If you want to keep root on stock rom follow this guide

And if you just want to move back to stock rom, unroot and relock your bootloader, use flashtool to relock your bootloader and flash stock ftf of your choice from here
