Update 17.04.8 Error

I wanted to update my FP2 to 17.04.8. The FP2 was rooted.
EMMC… has unexpected contends
(status 7)
Installation aborted.
Factory reset, wipe cache, installed FP2-gms75-1.12.0-ota.zip
It is working.
Install FP2-gms-17.04.8-ota-from-1.13.0.zip. The same error.
You can clean up the EMMC?
I do not know how to continue.
