Channel: retapac

Storage/RAM: 64GB/4GB

Use the Download links, not the Source. The Source URLs can only be accessed when the Motorola Update Service is downloading the same version (different version might be OK, I didn't test). When the Motorola Update Service is downloading, the OTA server temporarily authorizes your (Internet) IP, so you can download it from your desktop or other devices (that shares the same IP). Otherwise, you would get HTTP ERROR 403. The links were accessible previously when my phone is updating, which was how I download the OTA zips (using my desktop browser).

ADB sideload or unlocked bootloader probably won't work. Other variants/channels/storage/RAM might work (not tested). As always, flash at your own risk.

When in doubt, check the metadata.json inside the zip. Earlier ZIPs are not available, I forgot to capture them.
