Good day,

I tried to unlock Zte Blade A51 but failed
the log:

Engine version 1.0.0.5343
Searching phone;
For an successful connection do the following:
1. Connect the phone powered off with the battery inside to the usb cable
Phone detected (@oem267.inf,%usbcomm_dl%;SPRD U2S Diag) (Driver version: 4.19.38.135)
Preparing to sync;
Port opened [COM34];
Entering diagnostic mode;
ERROR: SCI USB2Serial port open failed;

Any help?
Thanks in advance
Regards
