Hello, excuse me
Model: sprd ZP5_101P
CPU: Unisoc UD710

I want to root this device and used the tutorial: https://forum.hovatek.com/thread-32678.html
I unlocked the device according to the tutorial: https://forum.hovatek.com/thread-32287.html and it can be opened normally，I think success。
But according to the tutorial: https://forum.hovatek.com/thread-32664.html, I used rsa4096_vbmeta.pem to generate vbmeta-sign-custom.img

fastboot flash vbmeta vbmeta-sign-custom.img

target didn't report max-download-size

sending 'vbmeta' (1024 KB)...

OKAY [ 0.033s]

writing 'vbmeta'...

OKAY [ 0.192s]

finished. total time: 0.224s


The device restarts, but I cannot turn on my device anymore.
Unisoc UD710 device，can not connect fastboot，what do I do？

you're unable to boot to homescreen? if yes, then flash back your stock vbmeta or firmware using research download tool
then confirm if you are able to boot into homescreen
also attach the info_image contents of your stock vbmeta
