Can not S-OFF via PowerAdapter.
And FRP remove via server failed.
How fix it?

1. FRP failed with error, or went OK but FRP is still on?
2. You can use TrustedReboot and then do a factory reset.

FRP show ok,but still on.
OK~I will try it.
thx lot

I try trustedreboot then do a factory reset, but got this error.
