I'm stuck in a boot loop on my ZTE Avid Plus Z828 MetroPCS Phone and I factory restored in recovery but unable to boot. I can go into FTM mode but it won't stay in FTM mode. Does anyone know where I can get a stock ROM for this phone? Support for this phone is extremely limited! I'm getting ready to chuck this thing in the trash. I ended up with this problem after trying to permanently root this phone following a thread. I was able to temporary root it with kingo root but when I reboot, I lose root. But now can boot up at all. I contacted ZTE, but they won't do anything if factory restoring it doesn't work. I can't afford to send it to them and have them fix it.
