Unhappy Need zte v768 (tmobile concord) stock rom!

I need help, i rooted my t-mobile a few months ago and i wanted to tweak the boring ui of the phone by deleting the launcher and installing a third-party launcher, among tweaking other apps. Without even thinking, I factory resetted the phone and when i turned it on it was missing many major ui apps for my phone to fully function. So i tried installing a custom rom onto the device, which only made the problem worse. Now when i turn it on it hangs on the android logo and then shuts off. Does someone have a system dump of the ROM, or even the stock ROM itself? If you do can you upload it here? Or can you give me the weblink to where the rom is on ZTE website? It would be greatly appreciated.
