[Moto Z2 Force  Questions & Answers] NewPoow:
I bought the device of a friend, used.

The device was locked, original, netflix did not work, I installed different versions and always the same error message.

Resolving to install another ROM to see if the problem would disappear, was when I unlocked the bootloader, and installed a downloaded version as taught in this post. I downloaded the RETAIL version and installed TWRP, so far everything works.

The problem persisted, resolving to return to stock and send for assistance, here the problem occurred:

- I did not notice my variant.

- I used RETAIL itself to lock and lock the bootloader.

- The TWRP's gone, normal.

- Flash failed to appear.

The wifi was corrupted, it only worked bluetooth, the mobile network also stopped.

Trying to solve the problem:

- I tried to enable the OEM through development.

- always gray, I waited 7 days with the appliance on.

- I tried to use the internet via bluetooth to see if I enabled OEM, nothing.

- I added my Google account, nothing.

- I tried RSD Lite, nothing.

- I tried Lenovo Moto Smart Assistant, it displays "Failed to match the connected device. Please plug it out, and try again." it's nothing.

- reset factory reset, worsened, the device is now disabled with DEBUG in the FRP screen, and it does not go away.
