if i flash stock rom will the phone go back as if i just got it from the shop and re locked
Well, what I can say is, yesterday I used an official update tool from ZTE Portugal, the one for Optimus Barcelona (it's a ZTE P736E) listed here, and my phone got back to "out of the box" state. No root, no recovery, etc.
When I downloaded that tool, and while running the application, it downloaded me a zip file. Inside that zip the stock rom should exist in order to flash it other way besides that tool. If I knew what to look for, I would gladly post the rom here. It's quite recent -> 28-12-2012.
