So, I've seen some posts concerning this and, at this point, I'm ready to purchase and replace the motherboard.

My daughter recently acquired a used Moto X4 (running Android 9 "pie") from a friend and she wants it de-Googled. I can get the unlock data to unlock the bootloader but Motorola says that the phone is unlockable - that would be because the phone had been purchased from Amazon (software variant / channel = "amz"). I think that if the ROM and bootloader could be replaced with stock (which, apparently could be done if the phone were on a lower Android version), I'd be in business but everywhere I've looked says that this is impossible - Motorola must do an amazing job of locking down their phones!

Since I'm just about ready to purchase a new motherboard ($60+ at cellspare), any "dangerous" suggestions are welcome since she refuses to use the phone as-is - can't say that I blame her.

You could try to flash the phone with the stock ROM of the google FI variant, but whether or not that works would be anybodys guess as I don't believe the IMEI would be changed. If you are planning to get a new device anyway, it couldn't hurt to try it and see before you buy another phone. I have the google Fi variant, and I know for a fact that the bootloader can be unlocked on it.

I have tried loading different ROMs onto a locked Motorola phone in the past - the bootloader will not permit itself to be overwritten without being unlocked. As I understand it, there's a hidden partition where a copy of the bootloader resides and, with the locked bit set, any attempt to overwrite the boot partition will trigger a check against the hidden partition and will prevent the overwrite.
