Need Help Can't Unlock BootLoader XT1700

[sfreddy15]

Hi guys, I will appreciate if someone can help me. The things is:
I erase system.img from recovery and I backup from XT1706. After I found a site with stock XT1700 rom I downloaded last version which is the S503 I used SP Flash Tools and everything goes well. But when I tried to unlock Bootloader again adb windows said: This operation is not allowed. I tried everything but I wasn't able to unlock Bootloader again. So I downloaded the first version (S116) and surprisingly I could unlock Bootloader. But I get no notification of OTA updates it says that phone has the last version which is not true. Any ideas of what could be happening here? Thanks of hand for you help.

If you downloaded the ROMs from http://motorolastockrom.com/motorola-moto-e3-xt1700 then I suspect the problem is the ROMs have locked boot loaders. I tried installing the S503 version and the S302 version and had the same problem as you. In the end I ended up installing an XT1706 firmware and was able to unlock the bootloader, but sadly it is the same release date and adroid patch version as the XT1700 ROM I was on to begin with (S124)
