update failed : "your system was damaged wireless update is disabled "

Hello .
I have serious problem with my GT1 ULTIMATE with fw GT1_311M0 and serial G912GSFG40617 32G.
In Update/Backup app found on-line update (OTA ) i think 20170509 about 20mb .
I choose to on-line update and show me this message :your system was damaged wireless update is disabled !!!!
I read in the net many people have this problem or bricked the device with this update .
Beelink do not say anything for reply .......
What happened ?
What can i do ?
