I have a tracfone moto e as well and i am getting the same exact error at the moment. After doing some research i discovered that tracfone registers each device with other anouther company. In my case they registered my phone with verison wireless(which is good when it comes to signal but not good for rooting as they dont allow it, like u said). I found out exactly who my cell was registered to by doing a reserse phone number lookup on my cell. It told me my number was registered with verizon which makes sense. also, i contacted motorola and they said that they do not support unlocking the phone. One last thing, some person emailed me claiming they were from tracfone saying that all i need to do is contact tracfone to have them unlock it. i may try this in a few days. Hope this helps somewhat even though i didnt solve your problem.
thankyou very much for the tutorial. I started it but when i finally obtained the long string of numbers, and requested an unlock key, I got an error messege saying that your device is not elegeble for bootloader unlocking.Could this really be or is it a mistake. I have service through trakphone if that makes any difference. I have allready tried unlinking my google acount to motorola Id an using different browsers and a different computer and sighning in with a different account. I double checked the numbers were properly copied with no spaces. Could trakphone be preventing bootloader unlocking? I know verizon does but i didnt find anything about trackphone. anyway thanks for your help.
