Not a duplicate as per other threads, due to the final step,
Go to Backup and Reset and do a Factory Data Reset. As per my other answer, this will remove FRP from the device. The FRP lock is still there in my issue.
I have tried the methods listed here: How to bypass "Verify your account" (Factory Reset Protection)
FRP lock on Samsung S5 Neo
Have full(ish) access to device
Using various methods, 5.1 Samsung camera download trick in this instance, I have access to Settings, and the rest of the phone. This is the 2nd time I have got to this stage as the first time, I followed the tutorial and did
Settings > Backup and reset > Factory reset > Erase everything; but the FRP lock was still on!! Even though it isn't in the videos.
I have now got to a stage again where I have device access, but this time I wanted to enable Developer options to enable ADB and force the change in the settings/secure Content Provider, however enabling dev options tapping Build Number doesn't work!!
