Greetings and welcome to assist. Unfortunately I can not find any firmware for your device on xda, I'm pretty sure flashing the wrong recovery has affected your partition table. If you try asking here
https://forum.xda-developers.com/android/help
hopefully someone will upload the firmware for you
Good Luck
