I just received an update on my S10E and now my screen is locked up with a aqua color background and a big downloading symbol in the middle.
It says:
Partition recover
Reson recover: Error verifying vbmeta image: invalid vbmeta header (6)
CUSTOM recovery
VBMETA G970USQU3DTC9, 29998301R
I have tried to force reboot, but it just comes right back to the same screen. I also tried to force shutdown, but it will not work. the power is staying on and the phone is staying on the same screen no matter what I do.
