Showing IMEI=0 after "fastboot erase all" (by mistake)

during flashing custom ROM, by mistake i run command "fastboot erase all"

after this its showing IMEI=0 and sv=06

My Moto X Play is dual sim variant, and its showing same for both IMEI.

I was searching from last 1 month and I cant able to fix it,

I tried to contact Motorola Service Center for this issue, they told "i cant do anything as your bootloader is unlocked."

for alternate solution they told "we will change motherboard to fix it".

its costs around 7000.

and its very hard for me to pay this much amount .

please help me if there is any solution for this issue.
