Good day

I have an issue with the recovery of the ZTE Grand X max Z787.

I recieved this phone and when I boot it up I got this message on the recovery and it doesnt boot properly.

Can you please tell me or help on to get the tooll to repair this boot issue and also where I can get the drivers of this phone?
One time I had the same issue with a LG Optimus LS970 when I made a bad root and I was able to repair it with some LG Tools and I think this can be resolved
