I need detailed instruction on how to recover a ZTE z828tl from soft brick caused by Kingo root!

I bought this “simple mobile ZTE Midnight pro LTE” off eBay, and simple won't unlock it, so I can use it with anyone else, so I was playing with KingoRoot trying to root it, the computer version said root complete please donate, the phone rebooted into boot loop, I can access the stock recovery screen, but can't do a factory reset, and I can get to ftn!!!

Please help, I am a newbie to android, cell phones, but have messed with tablets for years, and usually can get a factory ROM restore for flashing, but this time I've searched all over without any luck..

I did the same thing as you and ended up in a boot loop but then I wiped the cache when I entered recovery And then restarted phone, let it boot up for a while then it restarted on its own. I immediately did the button combo for recovery again and then did a factory reset. I downloaded SuperSU and was still rooted. Hope this works for you. Please let us know.

  • so basically MTND G you did a factory reset installed SU right after and you was good?

  • To be more precise. No. I wiped the cache. Then let phone bootloop a few times and THEN did a factory reset. Phone booted normally then I downloaded and installed SU and all was good.

Try installing ADB and then going to FASTBOOT MODE inside of your phone or tablet. Please download the the .img file for your version of android and device specific.

------Commands------ fastboot oem unlock fastboot flash (.img file location) fastboot reboot

that should fix it just setup your phone again!
