need unbrick LG K371


I killed this phone by downgrading it from 11n to 10b
Now, phone is stuck at 9008 mode.

I cant access it using CM2QLM, looks like Loaders issue...

and LGS only accepts connections using Download Mode (which I cant access)

I have a backup of the original Firmware before the brick, Read with LGS

MSM8909__LG-K371__K37111n__V11n__AOSv6.0__LGK371AT-00-V11n-ATT-US-SEP-29-2016-ARB01+0

Is there any way to unbrick the phone ?

Hello

not a driver issue.
I said 9008 mode because it is the mode everyone knows... but it is in care suite emergency mode drivers
