- find out device code: https://support.mogaanywhere.com/hc/en-us/articles/201302920-How-do-I-find-my-Android-device-s-model-number-
- find out if there is TWRP for the device code: https://twrp.me/Devices/

Liberating your device from google voids the warranty.
If it fails and your backup does not work correctly, you risk that contacts or data are not available anymore.
If you have to use unofficial LineageOS or TWRP builds, because the device is not supported, the installation can fail. Then you'll have to flash the stock rom, and restore the backup. It's a nasty effort.
If you have to flash the stock rom, you can only login and use the phone, when you log into a Google account, that already was logged into the phone before you flashed it. Be wary if you bought the phone second hand/online.
