Moto G5 Plus(XT1686) Soft Bricked|| Not Flashing || Stuck in bootloop || CID: 0xDEAD

My Moto G5 Plus(XT1686) suddenly stuck in bootloop, i tried to flash it with latest firmware available (lolinet mirrors - firmware, software, iso etc.) but nothing happen, it is not recovering from bootloop.

After some troubleshooting, i discover the CID:0xDEAD is showing while running getvar all command.
Does CID:0xDEAD is the reason for flashing faiiure? If so, then kindly help me to recover CID partition back to normal.

I don't want to loose my userdata, i have some important file in there(messages, photos).
Kindly help BROTHERS.......:(
