Flash the security backup (that was created during the unlock operation) back to this phone.

@ ionut5663,

ZTE Z835 phone model is not supported for the unlock purposes by SigmaKey, at the moment.
Currently this phone model is supported for the FRP Remove operation, only.

Before servicing phone, please check whether required phone is supported and what operations are supported for it by following this link.
