Why would you do that? If it's working, don't f(%@ with it. From what I've read, all the new firmware contains the "clone Kill" code which will brick a clone on or after the 10th boot. You'll find out soon enough if you have a clone.
And is Shenzhen Yojia Technology Co., Ltd. the actual manufacturer? Could be they're just another Manufacturers Rep. The About Us page has an exterior picture of a building, sure, BUT THERE'S NO NAME ON THE BUILDING. NO LOGO, NOTHING. There's some type of logo on a sign, but it doesn't resemble the bird on the website. Could be the local clinic for all we know. If they are the originator of the openbox, and wanted to enable someone to see if their openbox did, or did not, originate at their factory, wouldn't you think that they would post the "Clone Check" software on their site?? I have 3 chinese sites in my bookmarks, all claiming to be the "original manufactory" of the openbox, and numerous other brand names. And none of them has posted this "Clone Check" software. So this brings up another good question: who wrote and released this "Clone Check" software?? If your afraid of getting a clone, and want only to "get the real thing", deal ONLY with reputable dealers. There's some listed on the top of the page.
