Did you perform a factory reset after flashing the new firmware?
This often is not necessary. But when you find that something is broken that can fix it.
I have used various strategies to handle these circumstances, they all start with making a backup of my current settings. (The reasons for that will become clearer later.) Then I try things in this order:
- flash the new firmware and continue as before
If that does not work, then:
- flash the new firmware (if you've done that already you can skip this step)
- reset to factory settings
- reload backup of current settings
If that works, great. But if not:
- flash the new firmware (if you've done that already you can skip this step)
- reset to factory settings
- reconfigure things manually
Most people warn against reloading a backup after a reset because it may restore something that conflicts with the new firmware. But that may not always be the case, hence it may work trying that as a strategy. It all depends on what has changed in the firmware.
Of course, you can't be really sure if loading the old settings does not leave behind some residual nasty that you haven't spotted, but if you have a complicated configuration, it can save time.
Who said these things were scientific?
