Hello all, i have a device that i am in desperate need of the stock firmware or ota update for. Its an older device ZTE GRAND X z777. If anyone has either of the files please message me or share them here. I have the device and the boot seems boinked but stock recovery is still functional so i can flash signed images. If anyone can help, i greatly appreciate it. (Iv looked all over the internet, hoping a user who has the device sees this)
