Warning: Before following these instructions please ensure that the device is currently using Android 9 firmware.
If the vendor provided multiple updates for that version, e.g. security updates, make sure you are on the latest!
If your current installation is newer or older than Android 9, please upgrade or downgrade to the required version before proceeding (guides can be found on the internet!).
While this may be a generic message, it is likely accurate (unles you find otherwise). My judgement would be that is is much better use of time to try to find the update, than to fix the phone after a failed install!
I’m sure you’re right. It would be prudent to install Android 9. The problem is that 9 was never offered as an upgrade for this phone. Android 8 was and is installed. I need to get an original ROM and the links so far are either bogus or dead. Will contact Motorola maybe as the links you kindly supplied seem to be dead. I have dropped a message on XDA maybe some one will know.
