[HELP] Need Moto Z XT1650-05 Sheridan Stock ROM - Stuck in a Bootloop!

Hello all,

I currently have a Moto Z XT1650-05 SHERIDAN Dual Sim from China. I tried to install TWRP and root it but messed it all up. Now I am stuck in a bootloop. I tried to flash the stock rom in mfastboot using the XT1650-05 GRIFFIN China Stock ROM but it gets to the "Erasing" screen with a droid and keeps looping from there.

Have tried to google all over for a "SHERIDAN" ROM but not able to find one either. Could any kind soul here point me in the right direction to save my device?

Thanks so much in advance!
