I factory reset my S5 using the recovery menu to try and fix battery drain issues after upgrading to Marshmallow, however after reset it asked me to enter my Samsung account details due to "Abnormal factory reset" to prove I was the device owner.
After entering the correct details, it then gives me the message "Processing failed" and won't continue.
My account details are definitely correct (changing the password by one character gives a different message), and I've never logged into the phone using any other Samsung account. I've had the phone since new.
Is there any way to regain entry? I can log into the Samsung portal on my computer.
